Kyosho Lazer ZX, ZXS, ZXR, Alpha

[YR4Dude]

Hi,

I didn't see a thread on the Lazers so I thought I would start one. I know you guys are out there because theres plenty of responses to the auctions I have on E-bay as well as other Lazer items I see that get bid on.

Anyways theres quite a bit to talk about since there were many different versions out there. So any off you guys looking at this, post about what car you have and talk about the hop-ups or features your Lazer has. I would like to hear from you guys out there because there's still alot I don't know about on Lazers.

Just to start off. I have two Lazers. A ZXR and a ZX. I also have an Optima Mid long wheel base converted to Lazer suspension.

I look forward to seeing some posts on the subject soon.:)

BTW, my name is YR4Dude because I also have a collection of various versions of Yokomo YR4s.:cool:

[Zod]

i still have my lazer ZX-R after 10 years and i still love it , i have race it against losi XX4 and it still is competitive after all these years , i will try to post some picture of my car soon ,

PS: YR4dude , i have ordered some special parts for my lazer , i will receive them at the end of this week , you will be surprised by those , can't say more , you will see, if you can can you post some pics of your cars, see ya

[fabolousRC]

Zod...if you are looking for some wierd parts for your ZX-R, YR4 dude is the guy to seek.

Anyway...I haven't had a chance to build my car yet cuz I've been very busy at work. I'm in the process of getting all the electronics first then move on to build it (damn..I kept making excuses for not building the car lolz)

Plus, I'm waiting for a Lazer ZX-Sport that's coming in the mail.

Oh..btw Roge...is there anyone interested of buying Turbo Optima rolling chassis? I have two and was going to fix it up...but I ended up with so little to mess around with it. If someone want it, LMK through my e-mail.

[YR4Dude]

fabulous, are you talking about a turbo optima mid? Or the old school chain drive turbo optima?

I've been looking to get my ZXR back on track. Its complete but missing electronics because I squandered all my electronics on my fleet of touring sedans. When it is more than three it is a fleet!

Anyways, my local track lately has regroomed the track to be 4wd friendly. It must be from the urging of the Team Losi guys who have been using the track to test their new XXX-4. So I'll sacrifice a sedan to run the ZXR. Do you think a Novak Atom can handle a D4 9triple?

Also, I am curious about this reverse oneway for the rear drive. I am suspecting that its the opposite of the front oneway thereby giving brakes to front instead of back. I'll let you guys know when I find out.

[fabolousRC]

one is complete rolling chassis of Optima Pro with gold chassis conversion and the other one is for parts only

Mine too..I'm concentrating on my tourings for now...I have about 6 total (just sold one..and might sold another by tuesday..but adding one by tuesday too lolz)

[fabolousRC]

I hope you receive that link, Roger..let me know what should I get.

[YR4Dude]

I got it. The link to the picture gave me nothing. So you'll have to e-mail me the pic. I want you to know that I don't have the axles or diffs, no susp. arms but I think I have plenty of the susp. arm pins among the other parts in my bin.

Send that pic and I'll have a look at it again.

[fabolousRC]

No axles? :( No diffs? :( no universal shafts? :(

[Albertt]

And was actually thinking about running it again. Right now, it's sitting underneath a desk (where it has been doing so for 7 years now). I didn't mod that much, added a slipper clutch, diff kit (to use Associated rings and balls), A&L motor plate and a body that makes it look like Schumachers ProCat. Otherwise, everything else is original.

My latest idea was to slap on stadium truck wheels on to give it added ground clearance, but I'm too afraid of breaking parts and having to deal with the hassle of replacement. Anyone is the same boat as me?

[Zod]

Hey albert , do you remember who made that diff kit, i remember a while back when Rc caraction made the review of some Kyosho models talking about that , i wounder if it's still available somewhere ?? :confused:

[Albertt]

I believe that MIP was the company that made the conversion kit. I don't even remember what it came with. All I do remember is that it allowed me to use Stealth diff balls and rings which were readily available at the time.

[adam lancia]

hi all,

i have 1 lazer and 1 turbo optima mid se. the optima is complete with lazer front and rear shock towers but i am missing the original spur gear. anyone know if the online shops stock these anymore?? the lazer is about fifty percent complete. i'm waiting on some parts from a local hobby shop to finish the kit. it's really good to see that there are still some guys out there that remember these kist. the optima was my first kit. it's still my favorite over my b3 and xx4. does anyone out there have any good lines on parts for these kits from hobby shops?? thanks,

adam

[Zod]

:p this is one of my first upgrade i made i while back for my lazer ZX-R it's an Heat sink motor plate

[Zod]

;) here it's back shot of the same piece but now you can see that i have another heat sink (this one helps a lot to cool down my modified motor)

[Zod]

These are new pieces that i just bought recently , i'm gonna install them this week-end
the two pieces that you see is the rear arm lock set and the piece standing in the middle sub chassi mount :D

[Zod]

and the last new parts is one of my favorites is the rear sub chassis mount ;)

[Albertt]

AdamLancia: Sorry, can't help ya with the Mid SE's spur gear. My neighbor has a Mid SE, but I don't think he has any spare parts. His is totally stock except for a 14turn motor, wheels and tires.

Zod: I have a A&L finned motor plate on my Lazer. It looks the same as yours, except that it is not anodized blue. I actually thought about buying the Litespeed motor heatsink back then. I also remember seeing the aluminum chassis pieces back then, but I wasn't interested. I also noticed that you have the slipper clutch and 100 tooth spur as well...so do I.

[fabolousRC]

I want those cool motor plates!!! See Roge, i wasn't crazy when I told you about those heat sink stuff!! :D :D :D

[adam lancia]

do any of the kyosho guys out there know of a company that makes 100t 48p spurs?? preferrably with the standard (current offroad) hole spacing for mounting them on a slipper. also, where could i find a motor mount?? i have hacked up a lazer alpha motor mount to kind of fit.....it looks pretty hack and i'm not sure if it actually lines up perfectly. thanks in advance for any help,

adam

[Albertt]

I believe that Kyosho put out a 48 pitch 100 tooth spur gear for the Lazer. I don't know the part number though.

[RichieRich]

The Kyosho Triumph uses the same 100 tooth spur/slipper combo. I have a part number but not with me at the moment. I can get it later.

[adam lancia]

thanks richie and albert!! i appreciate the help,

adam

[RichieRich]

Adam - The part number for the 100 tooth spur is TM-7. It's used for both the Lazer and Triumph. The spur gear is Kyosho specific. I don't think any other gear manufacturer made a 100 tooth spur compatible with the Lazer/Triumph. Good luck finding one. I think they are exceedingly rare. :eek:

[YR4Dude]

Adam,

If you're looking for a motor mount for the ZXR, I have them. Send me an e-mail. On the gears, you may want to try Robinson Racing. They made many parts for the Kyosho Mid as well as the Lazer so you might find it there.

[adam lancia]

YR4dude,

thanks yr4!! i am interested in the motor mounts. i'm interested in getting 2 of them. i tried to get your email through your profile, but it wouldn't let me. email me at tango4_4@hotmail.com and we can talk price and all that fun stuff. are these the original motor mounts?? thanks again,

adam

[YR4Dude]

Believe it or not, I do not have an instruction manual to any of the Lazers. So here is my question and possibly one of you can answer this from your manual.

On the Lazer ZX, the main gear has diff balls and plates that actuate the gears to the front and rear diff. It almost looks as if the main gear is acting as a center differential. Is this true? Also the center oneway seems adjustable but doesn't seem to stay on adjustment, is there supposed to be a spring of some sort on the adjusting side?

Thanks to anyone who can help.

[Albertt]

You are correct. THe Lazer ZX had a center differential, but Kyosho decided to do away with this feature in the ZX-R (which is what I have) and put in a slipper clutch and a one way bearing on the shaft in it's place.

[YR4Dude]

Thanks Albert. Maybe you could answer another question. I have two different oneway drives for the ZXR. One is the regular drive that freewheels the front and another says "Reverse Oneway" what is that supposed to do? Is it the reverse effect? Does this means it freewheels the rear instead of the front. If so does this mean front wheel braking instead of rea wheel braking? I haven't tried it yet but I want to know before I do.

[Albertt]

Sorry dude, don't know what a reverse one-way does for the ZX-R. What does it look like? Where and how does it install? If you have some pics of it, and where it's supposed to go, I might be able to figure it out.

[Albertt]

http://www.rcmaniax.com/offmani/images/rcrlazer.jpg

and don't hold me to this, but I think it was a version sold only in Europe and Asia...basically a team modified ZX-R. I remembering hearing that it had a more optimized chassis, thinner belts, different shock towers, hard-anodized shocks the usual factory race team goodies.

[YR4Dude]

So how do we get a hold of one or at least the parts for one to upgrade our current Lazers?

Do you know any sites that would have more info about this car?:confused:

[YR4Dude]

XX-4 may be a good car if you have an unlimited supply of front suspension arms. The truth is, most of us don't. This is why 4WD is dead. However, the Lazer is tough in the front end dept so breakage like the XX4 is not a problem. Its just a matter of finding the right parts to make it work.

Keep in mind, the XX4 is wide. It is almost .75in wider than my Lazer ZXR. However, the only wheels I could find for it has a positive offset so if I could find wheels to fit that has a more negative offset, I might be able to meet the width of a XX4. This would help in stabilizing the handling of the car. Anyone know where I could find those rims?

[Albertt]

The Lazer...great car...efficient drivetrain...a little top heavy...weak front bulkhead.

The XX-4...fast because it was light...handled great...innovative belt drive design...the lightweight suspension components meant a lightweight wallet unless you "never" crashed.

Schumacher ProCat...great suspension design...interesting belt drive configuration...expensive to replace parts...and you had to wait a year to get them.

Yokomo YZ-10...oldest design...great drivetrain layout with the low beltline...indestructable suspension components...weak magnesium bulkheads that were improved upon when swapped for aluminum pieces.

I started off racing a Tamiya Thundershot...got dusted by a few Yokomos and Lazers and realized that I needed a new car. When the ZX-R came out...I gravitated towards it because a buddy of mine had an Optima MidSE and was always raving about how great Kyosho was. After about a year of racing...and having tried out all the cars I mentioned above, I realized that I should have bought the ProCat. I had got out of RC by the time the XX-4 came out...but that same buddy of mine went out and bought one...it was fast...but it broke frequently. Also, the XX-4 lacked that certain something the YZ, Lazer and ProCat had...it lacked soul (kind of like comparing the driving feel of a BMW M3 to a Ford Mustang Cobra).

[raptorcls]

heeeyyyyyyy!!!!!!!111:D

[raptorcls]

heeyyy!!!!:D

[CalmCyclone]

I remember the YZ-10 ... it was the car that got me interested in 4WD. My buddy had one and I drove it a few times. I couldn't afford one myself though.

I wonder how that beast would do today...

Hey ... wasn't the YZ-10 picked up by Associated for a while? I seem to remember looking at a Tower catalog way back when and seeing an ad for an Associated YZ-10.

Roge, HPI used to make them..it's called SupaStar *j/k*...HPI Superstar for Kyosho 4WD 2.2s fronts and rears. I had them on my old and sold ZXR...(if I could only get it back...*sigh*)

Lazer weak front bulkhead? It was weak front shock tower to me and I do mean I crashed a lot too :D

I started and ended my early racing career with a stock Boomerang. I forgot that I have a Technigold at home cuz I could've gotten decent lap on the car. Ball bearing was REALLY EXPENSIVE back in the days...I wish I can have the access to parts (and money) back in the days...the story would've different

I just recently bought another ZXR kit which I haven't had the time to build it and a couple of old school Optima chassis that I'm trying to revive. Too bad...there aren't any close local offroad track around here anymore...the closest one is an hour away and I have a tight schedule to get around it.

[YR4Dude]

Okay, heres another idea.

Does anyone know if the HPI MT suspension arms fit the Lazer??

Keep in mind, HPI's chief designer used to design cars for Kyosho.

If it does, then you're guaranteed a good supply of spare parts at any hobby store. Not to mention the MIP CVDs that are also available. Now that would be something worth trying.

[Albertt]

JG made a conversion kit for the Lazer to make it a race truck. THe kit came with rims, body mounts and a Ford truck body.

I don't think the Lazer needs new suspension arms...but stronger bulkheads.

It's worth a shot though...a 4WD truck that can compete against a RS4MT. Unfortunately, I don't have any plans for my Lazer...just purchased a TB01 and will run that rally style...

[YR4Dude]

Ah Rally. It was a fun class while it lasted. My car was a converted Yokomo M2 Pro. Anyways it was hard to get the car the car to stretch towards the 200mm width to gain stability. Plus saddle pack batteries on Velcro straps does not hold well in an offroad environment. I don't know what your rally track is like but we were running ours with the offroaders.(i.e. double jumps, table tops, etc) The best one I saw was Tony Phalen's pre TC3 rally.

Anyhow, still got rally wheels, tires and an unused painted Ford Focus body in case I decide to do it again.

BTW, I was thinking of using the NMT arms to extend the width of the buggy to compete XX4's not to convert to truck.

Here's another thing, Lazer parts are still alive at Tower except under another name. Diffs, belts, and pulleys are still available as TF parts. Also, wheels and swing shafts from the TR15 have always been compatible.

We all know that the Lazer 2000 is another car but, a close look at the bulkheads show that it may be compatible. I am not so sure on this one. So perhaps someone can confirm this. However, if it is compatible, it may solve the problem of finding the front bulkheads everyone is talking about that breaks. Perhaps, maybe, that Kyosho molded the new front bulkheads in a softer material so that it is more durable.

Something to think about. Lets hear your feedback on this guys.

[fabolousRC]

I know that HPI RS4 pro2 suspension arms fits TB01 :eek: :eek: :eek: (but you didn't hear that from me though)

[Albertt]

This is OT, but who cares... :D

I know that HPI RS4 pro2 suspension arms fits TB01

Really? But why would I want to put Pro2 arms on my TB01. They don't appear to be much longer and the TB01 arms are indestructable (and heavy). There is the LSA kit for the TB01...but I don't plan on getting that.

Sorry dude, I just have no interest in bringing out my Lazer anymore...if I decide to off-road again, I'll probably buy a stadium truck.

This Lazer 2000...what does the chassis look like?

Stadium trucks are a dime-a-dozen!! I got myself a used T3 for $50 with parts enough to build another one. Just about everyone is offroading with a truck. Take a look at the entries for truck vs. the entries for buggy.

Thats not why we are here in this forum. Also notice on your own previous post on the Lazer, that it is still basically unchanged!!! Either that is a statement of the enduring design of the car or a larger statement about 4WD offroad not being worthy of any further development.

Do you think Losi will spend the money to develop another 4WD buggy just to compete against themselves??

Sure its more economical to run truck than 4WD. I can appreciate that, but its even more economical if you don't run anything at all!! You either are for running 4WD or against it. Obviously, the 4WD trucks didn't catch on, hence RS4MT.

This thread is not just about the Lazer but it is also about the 4WD class. All of us have had the same cars sometime before and they were all 4WD. I've had a Thundershot, Boomerang, Optima Mid, YZ10, and even a PB Mustang.

My interest in the Lazer is that it is the most durable with the best handling of them all. I am sure there are ways to re-enforce the bulkhead to make it more durable. So thats why I am here and thats why I am trying to make suggestions for anyone else interested in running 4WD with the Lazer.

[Radzactine]

Hi,

Lazers really are good 4 wheel drive buggies.
I have 3 of them 2 of which I run now. They are so tuff. If I only had some video of the huge crashes I've had, and so far nothing has broken yet.:) My first lazer (all of which are ZXR'S) I found on ebay Australia and got for $250 Australian, only about 6 to 7 months ago. This was NIB brand new from a bloke that calls him self oz,rc. He has lots of classic kyosho new in box even old option house hop up parts. He may still have some lazer kits including the ZXR. And I am pretty sure he ships internationally. My second and third car I bought off ebay.au also they came with alot of spares. All my cars ars stock, I run a orion pro bb stock motor and a orion 15 turn x2 rush motor.
Gearing is a real problem for these cars I have found that the rear bulk head is to close for larger pinions, and finding spurs of different sizes or even stock ones is almost impossible. The manual states lots of pinion sizes to use but the stock one is the biggest I can fit and the car seems to be under geared. The problem is that on the track my car with 15x2 motor is not much faster than a losi 2wd buggy with a stock motor Imagine what a hot xx4 would be like against it :(. I can still beat them no worries through the tight stuff hehe.

Has any one really got these cars to fly? What combination of motor, gearing ect. did you use?

Also as my lazers came with manuals, feel free to ask me any questions for part no. ect. and I will try to help.:D

[fabolousRC]

If any one dose I do, I'm the 'L' in A&L, I'll take a look and get back to you.

OZ RC is one hella good guy, bro.

About your spur gear problem, as far as I can remember, Kyosho built Lazer ZXR to address ZX's problem with spur and pinion combinations (read: Limited) if I can remember it correctly when the car came out and was being reviewed by RC Car Action mag back in 91-92, the slipper clutch mechanism was being design to accept standard 48 pitch spur and pinion gears as well as 64 standard pitch combination.

I just acquired some of these spur and pinion combination and do have a ZX Sport readily available to be my guinea pig. Hopefully, I am right...otherwise, I'm stuck with 25 Tooth metric 48 pitch :(

[Albertt]

So thats why I am here and thats why I am trying to make suggestions for anyone else interested in running 4WD with the Lazer.

If I ever get the urges to off-road again...I'll slap on some HPI stadium truck rims on my Lazer...and bring it back from the dead.

Fabulous,

Daryl has been around in the RC business for the past 7-10 years under the name of Factory Works (http://www.factoryworks.com/index2.htm) . They have been supplying the Volvo bodies for sedans before it became popular with other mfg. Of course, he still has some parts for the Lazer and Mid. I have an A&L trailing arm chassis for my mid with Lazer front arms. Its a truck because the buggy rims don't fit the trailing arms. So if you're considering something different, you may want to consider an A&L conversion.;)

[Zod]

I have to say that YR4Dude is right the lazer is still a competitive car to race , many racers that see my lazer ZX-R perform at the
track understands why , i ran an 9 to 12 turns motor in my car depending of the track and it's a real blast , i recently installed two front shock tower back to back to improve rigidity in the front , maybe i will do the same thing in the rear but not for now . 4wd electric cars are a blast to drive and i hope that this class will rise even more when losi releases the new XXX-4 , Then maybe i'll switch to the Special edition of XXX-4 , but for me i didn't see the point of changing my LAZER ZX-R for a XX-4 (not the world edition) these cars broke two many parts for my taste.

Happy 4wd racing for ALL:D

[Radzactine]

Hi

Reply to fabolousRC:

Yes oz rc is one hell of a good guy .
He got my lazer kit to me in 2 days (turns out we live close)
cool.
With the spur / pinion gear thing,from memory I am certian the manual states that the are different pitch combinations available and, supplied in different pitches, to different places around the world, I think. There is a small table in the manual with all the factory combinations that were (are?) available. I can copy this table if you dont have. All my stuff is packed away at the moment waiting for my house to get built, but I can still get to it no worries. I cant remember what pitch my gears are will have to have a look at that. It is fairly fine I think.

Hey Guys,

The point of this thread is not just about 4WD offroad but 4-wheeling with the Lazer specifically. This was a car that was somewhat ahead of its time is some ways and if it hadn't be distributed so poorly, it would have proliferated throughout the industry in after market hop-ups as well.

Given the offerings currently available, the Lazer is still a considerable choice because of its handling capabilities on rough tracks and its durability. Yea, the front bulkhead is a problem but that can be fixed easily. However front arms that snaps easily can only be remedied if you have access to some sophisticated machinery to make them out of more durable materials.

So, you ask, how can we fix the front bulkhead problem? First of all, you all have to understand that this is a hobby. So finding "creative" solutions to simple problems is part of the fun.

Okay, my suggestion is to get some small blocks of nylon or polypropelleyn plastic about 3/4" square and about 1/2" thick.

Cut it in half diagonally with a Dremel or hobby knife(patience is a virtue). These diagonal blocks will act as further support for the shock tower which will be bolted through the top plate.

Now these blocks need to be fitted and holes need to be drilled.

Take the triangular block and put it along side where it is to be mounted. Note that there are things to be cleared before it can be mounted flush. Using a Sharpee marker roughly draw where clearanced need to be made to help it mount to the shock tower and top plate flush. Also check the angle because it is not exactly 90 deg at all. So you may have to cut the block again to achieve the proper angle. Using a dremel with a fine or med tip end cutter, cut out portions or the block to make clearance according to the markings from the marker.

After you're done, check the fit. If it does not fit check where you need to remove more material and adjust accordingly.

Once you get a fairly flush fit between the top-plate and the shock tower, you need to drill the holes for mounting. Mark the position for the top-plate screw and drill accordingly.

Using a knife or Dremel again, cut a notch where the top-plate screw goes such that the screw head would have a flat surface to sit on.

Now at this point you can stop or choose to go one and drill additional holes in the shock tower onto the block/wedge to fasten it to the shock tower. Mounting it to the shock tower is better but would require removing the top-plate screws to access the front diff. Not bolting to the wedge would only support the front shock tower and bulkhead from anything pushing it but would not provide any further strength if something were to pull the front shock tower away from the car.

Now you have a bulkhead that is fully supported. Provided that you are using a bumper to protect the lower front portion of the bulkhead.

So all we Lazer enthusiasts now need is a wheel with a deeper offset so that we could gain that cm of width to keep up with the XX-4's width.;)

any of you lazer guys interested in a freshly built lazer zx-r with some aftermarket stuff?? if so, drop me an email at tango4_4@hotmail.com. make me an offer,

It will be a little while before I post step by step pictures of the brace.

The above post on the brace was figured just from looking at my Lazer ZXR.

I will try to get you pictures of my brace once I get the chance to implement it, but you guys should have enough imagination to figure a brace of your own based on what I have described.

Anyhow, there's still the problem of extending the width of the Lazer by another 5-7mm on each side.

Hi folks!

Just discovered this thread (actually I was looking for a brushless motor thread I was reading when my PC rebooted suddenly...
didn't find it yet :( )

After 15 years of abstinence (sp?) I bought at ebay a used Lazer ZX - it came out it's an ZX-RR I tuned up with some alu and I have also this heat-sink for the motor - I also put in a carbon-fibre chassis!

It's not on this pic here, my ZX-RR looked like this when I got it...

http://mike-high.bei.t-online.de/pictures/PIC00001.jpg

Well I got hooked up then on the Tenth Technologies Predator and I own a Yokomo MX-4 - which is my favorite buggy - too.

Mike

[Micha_MX4]

well - I meant abstinence from RC-Cars - NOT alcohol ;-)

Does anybody own a Lazer ZX-S Evo. I mean the car the Kyosho team drivers race with...

Dang the Lazer looks sweet. Especially the Evo...drool. :) It's really too bad that I can't get Kyosho parts at any of the lhs's.

[Micha_MX4]

i think almost one year ago, I got two sets of CVD's from
Kyosho, which I thought could fit my Lazer ZX-RR.

well, today i built them and tried if they would fit - and they did!

while adding the CVD's I rebuilt the front alu hub carriers, I made
a mistake the last time...

thanks to the alu conversion in the rear i could add the CVD's there too...

(and yes, I cleaned the shocks too - after the photos...)

Cheers,
Mike

oops I forgot to post the Kyosho partnumber of the CVD's
(that fit in the front of ZX, ZX-R, ZX-RR !

"Team Kyosho, CVD GP10, #57453"

[YR4Dude]

Micha - Nice car!! However, those shocks don't look like any Kyosho shocks I have ever seen before. Are you sure they're Kyosho units? They maybe some other brand.

[Micha_MX4]

hmmm - let me check the manual...

these are the original ZX-RR shocks wich are different to the ZX-R
shocks. there is just a small booklet for the specific parts of
the ZX-RR (i.e. hocks and ball-diffs).

if you want to know more - please ask!

Hello, here are some pictures of my 1996 Lazer ZX-S. This is the original S model, not the new 2002 "Evolution". From the pictures you can see that it came from the factory with Team Losi shock absorbers and very cool 4 bolt wheel hubs similar to Yokomo's. The aluminum hubs are also wider which pushes the ZX-S's wheels out to the same width as a XX4. The front kick-up has also been molded into the carbon fiber chassis. Besides the suspension arms the S is almost a completely different design compared to the original Lazers. The front bulkhead and shock tower have been redesigned so breakage in that area is no longer a concern. From what I can see the new Lazer Evolution is almost identical, except for the carbon fiber shock towers and Kyosho shock absorbers. It would be great if Kyosho would sell the Evolution in the United States. It is definitely more durable than some American 4wd cars I know of LOL, and it has a superior motor/battery layout compared with any other 4wd car available now.

first time I see pics of a Lazer ZX-S...

I admit that I started thinking the "ZX-S" is a short form for
"Lazer ZX-Sport" which doesn't even come close to a ZX
from the tech side.

I like how they reduced the rear diff housing to two carbon
plates - probably kills you while trying to clean it ;)

How much had you actually to pay for it at your LHS?

My ZX-RR had a list price of about 750$...

One thing - would it be possible for you to post the
manual (or send it via email to me)? I could try to do
some hop-ups to my ZX-RR with ZX-S parts...

My Lazer ZX-RR from -94 (got one of the few that were sold in Sweden)

I really miss it now!

[Bappe]

[Bappe]

My Lazer ZX-Sport from 93, it had custom made shock towers that were lowered do handle bodies like the one on the picture. It also had ball bearings and a slipper clutch attached...

[Micha_MX4]

bappe:

did you run them just indoors?

what happended to your ZX-R?

Micha

[Bappe]

I sold them both...
Yes, i ran them indoors, before the touringcars came we raced the buggies indoors in the winter here in Sweden. It was really fun to run them with foams on carpet, especially the 2wd buggies were really fast! but the indoor class died when the touringcars came.

[cwginkc]

Hi Micha, I will try to post some pics of the manual for you. They may not look that good though, because I do not have a scanner.

I only saw the ZX-S for sale through Tower Hobbies for a short time in '96. It cost $630 back then! The new Evolution has a retail price of 38,000 yen, which is around $300.

I think you are correct. Maintanance on this car probably would be a hassle. Although I do not know for sure, because I have never driven it. It is just a show piece along with my Avante, Works '93, Yz-10 '95, and Turbo Optima Mid Special. The last Lazer I drove was a ZX-R back in 1991.

[Micha_MX4]

Wow, thanks for taking the pics of your manual!

Unfortunately the pics are to small in size to be sharp

As I have DSL and some webspace could you mail me the pics
(size about 200kb jpg each pic is good) I will upload them to the
net and show them here, if that's okay with you. (like the
ZX-RR sheets some posts before)

Others might be interested too in the design details of your baby... :)

Again thank you!

I didn't print them out yet, just had a short look at them
while processing them.

converting a ZX-RR to a ZX-S looks possible - diff housings,
chassis (not sure), upper front wishbones and suspension
bridges, top plate.

Probably less expensive to buy a ZX-S...

Somehow the front suspension reminds me of the 8th scale
buggies. Why did they do that? You can't change caster - 'coz
of the C-hubs - through changing the position of the upper wishbones.
:confused:

Thanx,
Mike

Hey Micha...You still racing that Lazer of yours?....i gotta say that your bodyshell (optima Mid) looks sexy dude!! :D

Ohh where might i get hold of any spares and where can i get that rear end setup that you got with regards to the rear diff housing made out of 2 plates of CF stuff..How that looks awesome!!

[Micha_MX4]

Hi John,

I got all my stuff (including my ZX-RR) from eBay.

Honestly I prefer my Yokomo MX-4 right now for driving,
my wife takes the ZX-RR if she's into it (she takes more
care...).

The carbon rear end is the Lazer ZX-S of cwginkc...

Micha

[JohnSheridan]

Guys....I got some Breaking news for ya..

But i dont think its approporiate to post it on this thread.
I think the new Kyosho 4wd yes you heard right a new 4wd from kyosho has been shown. I have some exclusive pictures thanks to my sidekick (Cronoman) who knows im a kyosho fan and brought it to my attention!!!..

So hows about it?..We need a moderator to make a new Thread, there i will gladly share witih you the exciting new project to have come from the Japanese shores...

[Micha_MX4]

don't hesitate - post it here and now!!! :)

PPLLLLEEEEEAAAAAAAASSSSSSSSSSEEEEEEEE!

[JohnSheridan]

Heheeh sorry Micha...To put this new 4wd car from kyosho in the same boat as the old lazers is really not fair..

We should respect the Lazer and also this new car that has been shown......Get one of the Moderators to make a new thread and ill post it without delay :)

[Micha_MX4]

Okay okay :D

I asked a moderator to open a new thread called

"Kyosho 4WD Offroad"

I'm really curious: belt or shaft driven?

Mike

[JohnSheridan]

Still belt but it sure damn look SEXY!!!!...I was droooling for ever staring at it..I hope this is a start for a Kyosho revival!!

Strap yourselves in boys..This can get overexciting..Soon as that thread becomes available i will post the new PICS :)

[JohnSheridan]

OK Doesnt look like they will take on my request for a new thread on this New 4WD Kyosho Car so i made a new thread in the "ELECTRIC" Forum for you lot to see the new car..Enjoy fellas..... Joe

[Micha_MX4]

got an aluminium ball raced steering and an aluminium
chassis post (wording?) at ebay.

I'll post the pics when the stuff ist mounted, which could take a while, coz' I'm totally hiped with my Mugen MBX-4 XR right now...

[crashnrun]

Hey all. I can't believe there are actually other people out there that enjoy the Lazers. I thought they were dead. I know that this is not the place to sell cars, but I wanted to see if any of you are interested in a new Lazer ZXS? It is the one with Losi shocks (the original ZXS.) I have one that is brand new, it has been built, but never ran. I never even installed electroics. It looks so nice I didn't want to mess it up. It has been a shelf queen for years. But, I am trying to make room for something new. So I am selling the ZXS. I have the Yokomo wheel adapters, the original box and instructions for it too. It currently has ProLine Holeshots all the way around. Oh yea the body, wing and underpan are unpainted still. I would like to get $250 out of it. I have way more in it but what the heck. I would also consider trades. I would like a B4, a Elec TC3 Team or the new Yokomo ETC.

[cwginkc]

Hi Crashnrun,

I am interested in your ZX-S. Please contact me. cwginkc@hotmail.com

[cwginkc]

Hi Crashnrun,

Do you still have the Lazer ZX-S owners card that came with the kit? Where do you live?

Regards,

Chris

[cwginkc]

Crashnrun,

I don't have any cars to trade you for your Lazer. Just good old cash. Let me know how you want to work this out as far as payment and shipping is concerned. Do you accept Paypal? Please send your reply to my regular email address shown above.

Chris

[cwginkc]

Hello everyone,

Just wanted to show off my new baby. A Lazer ZX-S Evolution. I will post more pictures after I assemble it.

Chris

[Micha_MX4]

very nice....

where did you get it and how much did you have to spend?

I hope you are finished with building soon ;-)

Micha

[cwginkc]

Thanks Micha,

It may be awhile before I build it. I am working on an older ZX-S now. I found the Evolution in Japan, and it probably cost more than it was worth. After obtaining the Evo I realized that the older ZX-S is actually a better car. The original ZX-S has a thicker one piece bottom chassis and includes the aluminum 4 bolt wheel hubs. Plus the Losi shocks are easier to find different pistons and springs for. However, the Evolution does have some nice upgraded parts, such as different rear axle carriers, a much improved bellcrank steering mechanism and thicker carbon fiber shock towers.

I was wondering where you located the CVD's for your Lazer ZX-RR? I have not been able to find them anywhere.

Chris

[Micha_MX4]

the zx-s evo is probably much lighter than the zx-s?

I got the CVD's from eBay for little money. It was a guess
that they fit, 'coz they are not Lazer parts but of a
1/10 fuel car. I think I postet their Kyosho part number.

I got a ball raced alu steering and an alu post for the upper
plate which I now have to add, 'coz I saw your ZX-S Evo ;)

Micha

[minijosh]

where can i get a new belt for a zx? mine is about 20 years old and it slips like it is on a banana peel. no roosters even with a mod motor.

[minijosh]

oh one more question, will the lazer 2000 body shell fit the zx or does someone have a extra just laying around? I need the body and wing plz.

[Micha_MX4]

my only source for Lazer Parts is eBay - I made good deals
and not-so-good deals...

You have to check often!

The Kyosho part number for the CVD's (they fit only in the
front or in the rear with the special rear hubs)
Team Kyosho #57453 "CVD GP10" Price looks like 3800 Yen - then

Have fun!
Micha

[minijosh]

I found that Dahm's make a shell for the Lazer. I think it looks sweet and for only 17 dollars with a wing, I might have a runner. Plus they sell a underbody for it too.

[Micha_MX4]

Hi,

Dahm's? (I live in Germany)

Do they sell online? Could you post the url?

17$ is a great price!

Thanks,
Micha

[cwginkc]

Hi Micha,

I took a look at the Dahm's website.

www.dahms-intl.com/d150.html

Not a very attractive body in my opinion.

I have been trying to find some CVD's using the part #'s you posted, but nobody seems to have them anymore.

You also stated the CVD's are longer than the stock rear universals, and cannot be used without the aftermarket aluminum axle carriers. I dug out my old ZXR, and the front and rear universals where the same length. I am wondering if the ZX-RR has more differences than I was aware of. I measured the length of my ZXR's front and rear universal's from pin to pin and they are 63mm. If it is not to much trouble, would you mind measuring your CVD's from pivot pin to pivot pin and letting me know how long they are. I am just very curious if the RR has the longer front suspension like the ZXS.

Since you live in Germany I have one more question for you Micha, could you tell me if LRP ever made a wheel for the Yokomo YZ-10 that was larger than the 2.2" IFMAR maximum? The black wheels on my ZXS are 2.26" in diamater. A salesman from Yokomo told me that LRP used to make BBS style wheels for the old YZ-10. I am trying to figure out what brand of wheels these are on my ZXS.

Take a look at the custom titanium hinge pins I made for the ZXS.

I bought a titanium hinge pin kit for the Traxxas Tmaxx and cut them down to the proper length for the Lazer, milled in new E-clip grooves, then gold anodized them.

Regards,

Chris

[V-one R Finland]

There is a ZX-S for sale at ebay.

[Micha_MX4]

but some parts are missing...

Did you see the Lazer that is in US eBay for 2000$?

@cwginkc:
Did you start building you Evo?

Micha

[cwginkc]

Hi Micha,

I haven't touched the EVO yet. I am still doing a lot of little things to the old ZX-S, like the custom hinge pins. I also learned how to anodize aluminum, so I am thinking about blue anodizing the motor plate.

Yeah, what's up with all of these ridiculous Lazer prices on ebay. So you have an old ZXR that won the 91 U.S. ROAR nationals. Big deal! Now if you had one of Masami's World champion Yokomo Yz-10's, that may be a different story.

$99 dollars for an instruction manual that you can get a copy of from Great Planes for $8 is ridiculous!

I guess I better keep my mouth shut until the end of the auction though, somebody out there may be silly enough to pay that much.

Micha, do you buy most of your Lazer parts from the German Ebay?

Chris

[Micha_MX4]

Hi Chris,

yepp German eBay is my main source...
I got nice alu parts at the German eBay.
My Yokomo MX-4 parts I get mostly at the US eBay.
Even if I pay the "at once" price it's less then a third
of the German price

I just checked the CVD's - the length is the same.
Sorry I have to correct me. 63mm's are both
the old cardans and the new CVD's.
It looks like the alu rear hub carrier stretches the track
by about 5 to 6 mm's.

I'll post pics soon today.

Chris,

attached you'll find the pic of the pack's label the CVD's were
in (a pair in each pack)

I was happy to find a "reverse one way" LAW-4 rear drive hub

Is this a part of the ZX-S Evo???

What's a "reverse one way" anyway?

Micha

[Micha_MX4]

i'll get it soon...

[cwginkc]

Thanks for measuring your CVD's Micha. That clears up a lot of my questions. Unfortunately I need some 66mm CVD's for the ZX-S.

I really am not quite sure what your "reverse oneway" is. The
ZX-S uses a different style oneway bearing.

Your reverse oneway looks just like a ZX-R oneway with a large aluminum flange on it. Does the package say it is for a Lazer?

Did you see the new pictures of the ZX-S on ebay? It looks like it has seen better days.

I will probably start building the EVO next week! :D

[Micha_MX4]

thinks will get clear if I get the oneway (got it for 1 Euro!!!).
It's a Lazer hopup number LAW-2 is the stabilizer set
LAW-3 is the carbon main chassis. The oneway was sold as
a Lazer part.

My ZX-RR has no oneway out of the box...

I didn't see the pic's you're refering to, can you post a link?

Micha

[Micha_MX4]

i mailed him and got the links to the pics (which are very
large so you need a fast internet connection)

I think the car looks "used" I agree with you.

Why did he take it apart?

Micha

PS: IMG_1512.jpg and IMG_1513.jpg are missing....

[cwginkc]

I see you found the pictures of the ZX-S Micha. Did you happen to ask him what his reserve is? I did, $600!:eek:

Wow, I can't believe the ZX-RR did not inlcude a oneway in the kit. Do you plan on installing your reverse oneway?

Chris

[Micha_MX4]

we don't have this reserve thing in Germany.

Is that what he want's for a minimum *LOL*?

A new Yokomo MX-4 is like 530 Euros in Germany
Keil claims to have it, 'coz it's still in his catalog
and -sorry just my opinion- a MX-4 outperforms
a ZX-S by far!

A brandnew Yok MR-4 BC Special ist 500 Euros

I think the car is worth max 150 $ 'coz it's not complete
and used - even that it's rare

HOw much did you pay for your EVO?

Please don't forget to get the weight (tech data sheet?)

Micha

[cwginkc]

Micha,

I just looked at your ZX-RR pictures on page 3. It looks like your RR has a oneway just like the one on my ZXR. There is a small 3mm nut that holds the oneway on the layshaft. If it is tightened down to far it will lock up the oneway. Try loosening that nut a turn or two and see what happen's.

Chris

[cwginkc]

Micha,

Sorry, I don't know the weight of the EVO. It does not have a technical data sheet. I would go out on a limb and say that it is probably one of the lightest 4wd's out there though. I paid $465 for it. Normally I wouldn't pay that much for a car, but I was curious to see how similar it was to a ZX-S, and I think it will probably be the last Kyosho car to carry the Lazer name.

Have you ever driven a ZX-S? It may be faster than you think. I know it looks fast just sitting on my shelf. LOL.

If you want the fastest car, you need to be driving a XX4. Just don't break it. LOL

I am really curious to see what Yokomo will be driving at the IFMAR worlds in a few months. Have you heard anything?

Have you ever owned any schumacher cat's? There not too bad.

We sure do have this Lazer thread going! Seems kind of strange since the Lazer's have been pretty much non existant in the West for almost a decade.

Chris

[Micha_MX4]

tried it right now and it doesn't loosen up.

I checked the manual and you are right LA-7 should have the
oneway clutch.

I got new spares and checked the front drive hub
and it has a needle bearing (lit. translated from German) in
it maybe it's just old...

the reverse oneway is a part that replaces the rear drive hub
LA-56. I hope that it will fit to my ZX-RR slipper.

I will replace my front drive hub this weekend (the manual
shows the setup but doesn't mention the oneway functionality...

[Micha_MX4]

oops I was to fast...

the pic shows the alu bulkhead I mentioned a time ago.

The next pic shows the alu bellcranks (ball raced) which
are not worth the money 'Coz they show low quality
(GPM is the manufactorer)

I just added them for the looks...

Micha

[Micha_MX4]

well Losi --- hmmm

everyone is driving it - I like more the exots (sp?)

I have some predators to build up again ;-) (four plus
one offroad in parts plus one touringcar in parts...)

Do you know that the MX-4 was world champion?

mine is fully carbon plus lightweight motor mount.

My alu CVD's (MIP made some rear one's especially for me
this spring ;-) ) are not build in yet, but this car accelerates
with my GM Evo3 12x4 like hell...

The only thing missing so far are titanium screws and
turnbuckels. But I think I stay with stainless steel screws
and the standard turnbuckles...

The cool thing about the Lazer is that it developed
so far from a "standard tamiya class" to a "race class"
car to compete with the best of the world (ZX-S Evo)

The pic shows not my MX-4 (mine has the new MR-4 BC Special
threaded shocks)....



Micha ;)

[V-one R Finland]

Hey guys, don't say bad things about my car ;)

You never know who are reading this forum......

I'll give you some answers.

The reason I took the car apart reflects to the time when I quitted off-road racing. Since then I have took parts for my projects (steering etc.). I also had TI -tierods in it from the beginning and those too are gone to another projects. I just recently noticed that this baby could be worth something :D

I know that the car looks like a wreck, but I will put it together again.

About the reserve: I don't necessarily have to sell this car and I sure didn't know it's value. Now I know. If it's not more than 190 $ I sure won't sell it yet. Hopefully I can get the front bulkhead to it from Kyosho Slotcar.

The missing pictures are now on-line. They were left out because of a mistake. Didn't notice it before Micha asked about them.

Hey, ZX-RR should have had a one-way out of the box. What did it have instead? The Lazer has had a oneway since the very first ZX-model (I have had it).

Have a nice day guys :)

PS. I'll tell you if I get lucky with the parts hunting. Maybe you wan't to buy it when it's put back together....

[cwginkc]

Sorry V-One R, Did not mean to hurt you Lazer's feelings.

So what is a ZX-S like to race? How would you say it compares to a MX4?

Chris

[Micha_MX4]

sorry V-one R!

first the car doesn't look like a wreck, I noticed after
my post that you put out the turnbuckles and therefore
the axles looked kind of weired.

I have just second hand Lazer's, where the oneway
obviously doesn't work as fine as in my MX-4
(or Predator). 'Coz of Chris I checked the manual and found
that there should be a oneway in it.
I apology hereby! ;)

BTW I payed 140 Euros for my MX-4 and it was like
NIB ! I know that I was lucky but the hustle to get
the bulkhead....

It's already difficult in Germany to get MX-4 parts
(I order them in England that's faster and cheaper !!!)
it should be even more difficult to get Lazer ZX-S parts
as they are so rare.

BUT THE LAZER ZX-S IS A REALLY SWEET CAR!!!

just wanted to point that out :D

How about the temperatures in Finnland?

Micha,

Thanks for posting details from your instruction manual. I have been out of this thread for some time. Been busy adding another little one to my family. Chances are, you probably picked-up your reverse oneway from me when I last sold items on E-bay. Anyways, I still don't know how it works myself either. I would guess it works in reverse of a regular oneway for the front wheels. In other words, the reverse oneway would give oneway action to the rear wheels instead of the front. If this is so, then this would shift the braking action towards the front rather than the rear as in typical front oneway scenarios. So instead of spinning out upon braking the car would have more controlled stops.

Give it a try and see how it works and let me know.

What I am really interested about your ZX-S Evo is the track width. Does it come with longer suspension arms and universals? If you compare the Lazer with the other 4WD you would notice that the track width is narrower by about 10 - 15mm which is significant. Please advise on the forum about that.

Its great to see you all in this thread that I started some time ago. I knew that I wasn't the only one out there still interested in the Kyosho Lazer.:cool: Keep posting and please keep this thread going. Thanks guys.

[cwginkc]

Yr4Dude,

The ZX-S uses the same A-arms as all the other Lazers, except they are the "graphite" versions. To make the front of the car wider they used different C-hubs combined with longer universals and wider wheel hubs. In the rear they only used the alumium wheel hubs to increase the width. With these additions the ZX-S is as wide as a XX4.
So far the only complaint I have about the ZX-S is how difficult they are to work on. I have owned virtually every 4wd buggy since the mid 80's and this one takes the cake for being the most difficult to maintain. Front and rear diff removal is a nightmare!

Chris

[YR4Dude]

cwginkc,

Thanks!! That really helps. In regards to the diff access issue, are you sure? Because the big difference between the Lazer and its predecessor; the Optima Mid, was that the Lazer had improved access due to the redesigned two-piece diff housing/bulkheads. Still not easy but better than dismantling the whole chassis like in the Mid.

Anyways can you help me please?????? Where can I find an online seller for a Lazer ZX-S like your? Either that or an Evo. I've looked all over the internet and only found a gallery showing the cars with great paint jobs. Also, there was one picture of a Lazer Proto. What is that???

It seems that the Lazer is still alive and well in Japan but strangely there is absolutely nothing about it on the Kyosho website. What's going on? Is this a Japan market only car? And all the big secrecy?

If you can shed some light on this, I would greatly appreciate this.

:confused:

[cwginkc]

Hi YR4DUDE,

Forget everything you Know about the Lazer ZXR's and Optima's. The Lazer ZXS is almost a completely different car. The only parts that are similar are the diffs (ZXRR diffs) and the A-arms, with the exception that they are made of the stronger graphite material. If you would like some close up pictures of my ZXS just give me your email address. You will have an easier time seeing all of the differences that way.

Actually taking out the diffs isn't to bad. It is putting them back in that is the hard part. I would describe the process to you, but it is probably more than you want to read, and definitely more than I feel like typing. LOL.

Sorry, but I can't think of any other suggestions to help you find a ZXS. You are doing pretty much what I did to find one. Just search the internet and check ebay. I got my first ZXS on ebay a couple of years ago. I got it for a good price because not many People in the U.S. are familiar with the Lazers anymore, especially the ZXS. I only gave $200 for it. The second one, I aquired here on this very forum. I got my EVO through a friend that was in Japan. I think I have enough of them now, LOL, so if I run across another one I will let you know.

The Lazer Proto is the newest version I believe. It is a lot different from the EVO if I am correct. Although, I do not think it is as good, because it has all its batteries on one side of the car and the motor on the other. Kind of like a XXXS. In my opinion this creates an undesirable distribution of weight out on the edges of the car.

Yeah, I wish Kyosho would have marketed the ZXS around the world too, because it is a very nice car that could have been very competitive in the right hands. I heard that the EVO was a limited production vehicle for Japan only, and was only produced after individuals and hobby shops put in advanced special orders for them. If you look around on Japanese websites it appears to be a very popular 4wd car over there. I am contemplating racing my EVO, but have not made up my mind if I want to risk breaking a limited production car, that would be next to impossible to find replacemant parts for. I will propably just get a Yokomo Mr4bc special to race instead. Sounds safer to me. LOL

Chris

[YR4Dude]

CWGINKC,

The whole idea behind my interest in the Lazer is that its a great handling 4WD that is not fragile like the Losi or the Yokomo. So are you saying that the later improvements to the Lazer has made it less durable??? Say it aint so.:(

Anyhow, from what you say of the Lazer Proto, could it be that they adapted the KX-One chassis to offroad? Also are the hubs taper fit or are they clamping hubs? One last question, which car's universals can I use to extend the width on the Lazer. I've looked at the Inferno 15's but they seem to be the same length. Is there another Kyosho car's axle I can use to do the same?

Thanks for the reply. Look forward to hearing from you again.

[cwginkc]

Hi YR4Dude,

I have never driven the ZXS, so I could not say if it is a very durable car with absolute certainty. Although, I have had several older Lazers, and the ZXS seems like a tank compared to them.

On my ZXR's, the front bulkhead and shock tower where the only weak parts in my opinion. The ZXS front tower and bulkhead seem to be very much improved in regards to strength.

One of the reasons I have considered racing the ZXS, is because I have a gut feeling it would be the toughest car on the track (Watch out XXX4's, I might hack you if I can't beat you). LOL.

I don't think the Proto shares much or any of its design with the Kx1. It would have been neat to see an off road version of the Kx1 though.

Yes, the ZXS still uses the tapered hubs. I think the longer universals might have been used in one of the older Ultima's. I don't remember which one though. Maybe the Ultima Pro XL?

W-5063 is the Kyosho part #. They are 3mm longer than the standard Lazer universals.

Do you still run a Lazer? What model is it?

Chris

[YR4Dude]

CWGINKC,

I've never been blessed to have had a Lazer in kit form. So far my passion for Lazers started from when I first modded an Optima Mid with long wheel base graphite conversion chassis using Lazer suspension conponents.

Afterwhich, I aquired a used Lazer from E-bay that was basterdized into a touring car. The guy had enough parts in the package for me to build two Lazers which I converted back to offroad. In doing my best to figure it out on my own, I was able to get one that I am assuming is a ZXR and another that is a ZX. Both have a graphite chassis(not woven).

Perhaps you could shed some light in what I have.

Supposed ZXR:

Graphite chassis, one piece graphite top plate, open belt, batteries toward rear close to motor with straps at an angle (not straight),graphite shock towers, front shock tower is angled inword like a bent horshoe.


Supposed ZX:

Graphite chassis, two piece top plate, covered belt, batteries more forward away from motor with straps straight, aluminum shock towers.

I had two transmissions, one with something like a diff on the spur gear and another with a slipper plate & pad.

Recently I aquired a Lazer ZXR on E-bay. It had the one piece top plate and everything like the supposed ZXR but the chassis placed the battery straps straight. It also featured an alum. motor bulkhead brace. It had graphite shock towers but the front one is straight up (like and Ultima) not angled in like the one I had.

One more thing, I also aquired a huge load of parts from someone in Australia some time ago for a very modest price. In the past year, I had sold parts from this package on E-bay. However, the chassis parts plus all the shock towers were made out of FRP. Also there's been several sellers on E-Bay selling ZXR NIB kits but its all made of FRP. I didn't think this was right because why would a topline kit like the ZXR be made in anything other than graphite? Is this some sort of Australian thing only?

It seems like you are the Lazer expert which is why I started this thread to find people like you and to help others who also share the same interest.

Thanks for anything you can contribute.:)

[cwginkc]

Thanks for the compliment Yr4Dud4e,:)

You are correct in identifying your various Lazers.

The Lazer you originally built from parts is what I refer to as an "updated" ZXR. It had the different shock towers, angled battery holders, different chassis bulkhead, transmission brace and various other differences. It is the better of the ZXR's. The original ZX used the diff on the Layshaft, ZXR got a slipper and a oneway bearing.

A couple years later Kyosho released the ZXRR. It had different shock absorbers, diffs, and I believe it included the Kyosho Electronic steering sensor.

The parts you got from Australia sound like they are from a Lazer Sport. It is the only Lazer that had a plastic chassis as far as I know. I have seen the ZXR's on ebay from Australia, I thought they did have the graphite chassis? Did the seller say they where FRP?

Chris

[YR4Dude]

CWGINKC,

If you check the description closely you will notice that it is FRP. I sold a few sets of ZXR FRP from that load of parts. I also have a load of plastic (Kelron) chassis for the ZX-Sport which are absolutely worthless.

That steering sensor you are talking about, is that a gyro? Sometime ago Kyosho did made a car specific gyro similar to those used in helis. GM even made an electronic speed controller that had that built in.

On the ZX-RR what type of shocks and shock tower was it? Did it use long shocks on the front or mediums? Also were they the same old gold ones or something like the old platinums which had adjustable dampening?

[cwginkc]

YR4Dude,

I don't remember the Kyosho Electronic Steering Sensor well enough to say if it was a gyro. It probably was though. I just remember seeing a picture of the RR box, and it saying it contained the unit, along with a small picture of it.

The RR had the same towers as your Lazer but different shocks. I believe Kyosho called them either Equalizer or Ultimate shocks. One of the two. They are more of a dark bronze color and have a black rubber boot at the bottom too wipe the shaft. They did not feature adjustable dampening, and are the medium length up front on the RR.

Can't tell you what is up with the Australian ZXR's. Does the FRP chassis look different from the one on your first ZXR? You know, it seems like every manufacturer has a different name for their chassis material. I just classify them into 3 groups.

1. White fiberglass 2. FRP like stuff, graphite, and 3. Woven Carbon Fiber.

Where do you live and race?

Chris

[YR4Dude]

CWGINKC,

I have a set of the Equilizer shocks but they're black plastic with an alum. cap ring. Is that the same?

Also FRP is also black in color. Here's how I classify it.

1) Fiberglass with whie epoxy resin like the Assoc.
2) FRP Fiber Reinforced Plastic. Black with rough white edge i.e Tamiya
3) Graphite plate. Two pieces of graphite with white foam in between, smooth edge. i.e. Composite Craft
4) Woven graphite

The FRP on the Australian ZXR and the Aussie parts were like #2 FRP. Also did Kyosho supply the kits with their own graphite or was it added in by the distributor? I often suspected that the US spec kits got it graphite from Great Planes where the chassis would be added in the box and then stickered and repackaged indicating that the kit features a graphite chassis. If anyone knows the real story please let us all know.

As for where I am..... I'm in sunny SoCal and when I can get away from my busy sched. I go to SoCal Raceway. 4WD offroad is dead over there but there's always people on practice days that are willing to run them. However 4WD onroad sedans is very much alive. Don't know why one and not the other. Maybe its because onroad has that big foam bumper.

YR4Dude:
I postet pics of my ZX-RR at page 3 (the red one) where you have a nice view at the front and rear shocks.

I also postet the manual with explosive view (you mentioned aboce.. :) )

Micha

[Micha_MX4]

well - "graphite" - I thought this was
referring to "duroplast" (german expression) plastic which is reinforced
by carbon fibers.
this "duroplast" is pressed under heat
and pressure in a mould. It won't become soft under heat like polyamide f.e.

the original chassis plate of my ZX-RR
is made out this material (my opinion)

Micha

[Micha_MX4]

HI guys,

on my ZX-RR chassis plate is a small
extra plate which I thought is for the esc
(not clear why an extra board). Was
that for the special Kyosho esc with
"ESP"?

http://mike-high.bei.t-online.de/pictures/lazer/PIC00051-klein.jpg

when installing the Lazer carbon chassis i put this plate in too 'coz it's nice if you have to work on yout steering servo...

Micha

PS: this esc sucks!!! poor braking - not adjustable. for fun driving okay though 'coz it's waterproof...

[Neon]

I have an old Turbo Optima Mid SE. I always seem to be breaking the Front A-arm's.

Is there anything better I can use from a Lazer or any other car that would take abuse better than the stock ones?

Here's the stock A-arm part number that I seem to like breaking.
KYOC6071 OT-069 SUSPENSION ARM SET

(Why o why they didn't make the fronts similar to the rears with their much sturdier design, I have no idea.)

At any rate if any of you Lazer/Optima Mid guru's have any suggestions, I'd like to hear them.

Aaron

[YR4Dude]

Converting over to Lazer suspension requires more than just the arms, it also requires new longer axles, hub carriers and steering knuckles. I've done the conversion using the mids steering knuckles and that requiered me to Dremel clearances in the are for me to get full extension.

Anyways converting over to Lazer suspension may not be feasible or cost effective to you. You may want to consider replacing it with aftermarket Mid-specific arms like those from A&L aka Factory Works. They may still have many parts avail. for the Mid.

[Neon]

I was hoping for more of a direct fit kind of replacement. Oh well.

I will contact Factory Works and see what they got.

Thanks.

Hey everyone,

I raced the ZX-S for the first time this Saturday. It seems to be pretty close to having a good setup for the track I drive at. I didn't have any luck trying to clear a triple jump, but I think that is because of me. I was just to afraid to really gas it all the way through the jump. (I still have bad Losi memory's) However it flew really nice and level over a big double. It even survived a couple of crashes that would have certainly broken a XXX4.

Chris

[Micha_MX4]

Did you race with some other guys
there? How was the turn in, etc...

Micha

PS: don't know why the post above is double....

[cwginkc]

Hi Micha,

Yeah, there where about 50-60 people racing Saturday night. It was the first race of the season, so I expect it to get busier as winter approaches.

Turn in under power is be pretty good, but it seems to push a little when you let off the throttle, even though it has a one-way. I am going to make a few changes to the setup before next week, which I think will help. Although, I must admit a lot of it is just me having to get used to it. I have not raced off road in a long time and I am used to how wonderfully the XX4 ran. Plus it is kind of hard to find good setup info on a Kyosho cars that is not sold in many parts of the world.

Chris

[rustymccoy]

ok got the buggy yesterday and have some compatibilty questions. the main shaft that holds the spur and turns the belts for the front and back is completely stupid! im mean it rides on a plastic bushing on the spur side and isnt mounted to any thing on the other side! plus the spur is a large 100 somthing tooth molded piece that has about a 1/2 inch piece that slides on to the main shaft. is there any way to replace that shaft and spur with a new slipper system with bearing on both sides? also what arms can i replace the cheap stock ones with? the cvds and cups need to go in back too! ive shimmed them as much as possible and they wont stay in! on a plus note the belt and diffs are great and work perfect. ill be shopping for new towers front and back also. the shocks are pretty short also. it came with some super cheap friction shocks. i tried to put the short front shocks from my rusty on the back but they were way too long. ill measure the stock ones and post some possible replacements soon. the chassis has a lil flex but i think after i replace the towers, spur set up, get a belt tensioner and guard it shoud be fine. any help on this project would be great. i think im going to take my dual bl project apart and make a bunch of CF parts for this ride since it will be more realiable and most likely my prefered racer when im done.

[Micha_MX4]

@ rusty

did I miss a previous post?
Which Lazer did you buy?
I wonder about the friction shocks...

Micha

[rustymccoy]

i believe its a zx but im not sure, i got it off ebay. it looks kinda like your red one a few posts up, but with out the carbon fiber. and the center brace/top plate is slightly differant too. the trany and motor area look the same tho. upon inspecting the shocks more they may have held oil at one time but that time was long ago!lol they are pretty cheap but it dosent matter i have carbon towers now so i can use shocks i already have. id really like some infor on the spur and its shaft.

[cwginkc]

This car is built like a tank and it's FAST. After several weeks of racing I can honestly say this has to be one of the best 4wd off road buggy's, (other than maintenance).

I have broke one rear A-arm, but that was due to hitting a 1" piece of angle iron sticking up out of the track at full speed.

It really is a shame Kyosho didn't price this car more competitivly and market it worldwide.

I am now looking forward to trying out the new BJ4x4 B4.

Chris

[Micha_MX4]

Hi Chris,

do my a favor and get the weight of your car

@rusty
sell the Lazer ZX and get at least a ZX-R so you'll have at least ball diffs.

Sorry for the delay Micha, I have been building a new car.

I picked up an MR4BC 2003 Special a few weeks ago on ebay. Seems like a pretty nice car. I haven't driven it yet, so I don't know how durable it is.

Have you heard about the BJ4x4? Looks like it will be the 4wd to have pretty soon.

hey all,

i have a ZX-RR and have a huge problem with the rear belt skipping and burning up within one battery pack...has anyone else had this problem?? i'm not running ridiculous mod's, just down to 12 turns. i tried rigging up a belt tensioner inside the case but that seemed to make it worse:confused: :confused: in the mean time, i've put the lazer suspension on my optima mid chassis with the optima mid transmission but with lazer diffs. hopefully i won't fry this belt and if i do i'll go nuts. i love the way the car handles...it seems to turn in better than any losi i have ever driven which is why i want to keep it going. i still race it but it has been more of a pain lately with the rear belt problems...very frustrating. any help is greatly appreciated. thanks,

[Lazerfan1]

Hi to all you Lazer fanatics out there My name is Ken and I have a Lazer that started out as a Lazer zx Sport and then I have slowlwy upgraded it to a FRP chassi and top plate and ball bearings and ball differentials and slipperclutch. Just reacently added A&L front and rear shock tower and front chassi support and Finned alumin heat sink motor plate and alumin front hub carriers that are ball bearring supported. and the Lazer ZXR front and rear wider suspension arms with Lunsfords Titaniam steel turnbuckles. I just compared the width to a Losi XXX4 Graphite and it is within 1 to 2 mm of the Losi's width wich is great and all I need to do now is get the alumin front steering Knuckles and rear alumin hubs and mip CVD's and I will be ready to go Losi Hunting at RCmaddness in Einfield CT. I still need to know is there is a belt tensioner out ther to be bought or made?? If anyone has any information about these parts that I need please help!! E-mail me at Rcgeico@aol.com also is anyone has a graphite chassi and top plate I'm ready to buy these parts in order to race this summer.Thanks Ken M.

[NIC]

Hi Ken M !

Is your rear belt skipping now after you have installed the slipper ?

I have raced alot with the Lazer ZX-RR both off-road and on highbite carpet tracks. The only time the rear belt skips are when it has a VERY high mileage on it. When I hear the first skip I change both the small pulleys and the rear belt . After that they will hold up ALONG time untill the next change. The part-number for the pulleys are LA-11 and LA-12 for the rear belt, incase you don´t have the manual. The long belt I have just changed once in 9 years.

As for the carbon chassie. Fibrelyte made thoose a few years back but they aren´t that hard at all to make on your own since there isn´t any "kick-up" at the front.
Juat mount a vaccum-cleaner or have a friend hold it for you to suck up all the fine powder. Wear protection for your cloths and always wear a "nosemask" when working with carbonfibre.
A 2,5mm lower and a 2mm upper plate will do the job just fine.

I know from experience that the belts will hold up. I drive with VERY powerful brushless motors in my Lazer. I have measured the topspeed of my Lazer ZX-RR to 71,8 mph (over 115km/h) with a speedtrap used for sprinters.
In that run I drove with a Hacker brushless motor and 12(!) cells with 29 tooth pinion and 72 mm pinkspft foamtires.
I have a small videoclip here when I drive with the same motor and cells but with 27T pinion and 64mm tires.
Speeds are around the 60 mph mark in the video going uphill.

[Lazerfan1]

Hey thanks for all the good information and no my rear belt has not yet begun to slip. Although the one new part that I'm looking for is the front alumin steering knuckles because these plastic ones that I have keep stripping out the screw holes and I loose the screws. So I fugure if I can get the alumin ones then use some red thread locking compound then they will never come out!!!! I'm also looking for some mip cvds that are approxitamitly 3mm longer than the stock drive shafts. Can you help me out in this cattagory?????? Thanks Ken M. Your video and your search for the clip did not work. Looking foward to seeing a Lazer being a TRUE LAZER!!! Later Ken

[welshy40]

Guys I need one of these, any one have one ??? I have posted pics of my ZX on the rc10b4 website under the thread '4wd buggies all welcome' on the last page at the end there are piccys of my lazer. Comments please

[Micha_MX4]

do you want it as an aluminum part?

I'll check if I have a stock spare part.

But I live in Germany though

Micha

[welshy40]

Guys - I cannot add my pictures on this site as they only take certain sizes - pity so go and have a look at ww.rc10b4.com and type in 4wd in the search field - then in the '4wd all welcome' thread on the last page at the end is my ZX, check it out guys, its brand new and for a car that I have raced since it came out I think its probably the best around.

I have redesigned the chassis to use the ZX-S bodyshell, redisigned the front shock tower, redesigned the top deck, and modified the rear shock mount. Plus the Zx steering is better than the ZXR as zero bump steer is required which the ZXR cannot give.

Any more info about what I have done to it just ask.

Oh yes one more thing - some one on this thread mentioned the tub chassis by fibre-lyte, guess who gave them the idea (me) for the ZX. They had designed one for the yokomo in the early days, and I designed one for the ZX (well the internal battery layout - so modified the battery position as I had the holes cut out), and so if you guys wanted the origional design I can get the part number for it from them (the zx chassis tho is different from the ZXRR and some ZXR's) as its in my file and no one else's.

Micha_MX4 - have you had any luck in finding this part??

[Lazerfan1]

Hey Micha Mx-4 if you do find any of those rear alumin subchassi mounts I'm in need of one also that is is you can find them. Later....I understan that they were made by A&L at the time!

[welshy40]

Lazerfan 1 - I think that no one really cares any more on this site, unfortunately for the 2 of us who still race. I think the best option is to find someone who can machine one for you out of alloy.

I doubt if anyone really cares about the ZX or any other on this site - its not on is it, I need this part due to racing really hot motors, and the only way I can win the indoor championships to qualify for the bigger events around the world is to at least try to keep the motor cooler.

[Micha_MX4]

Sorry guys,

I think I posted that i don't have a spare
alu mount.

Just stock plastic.

[YR4Dude]

Hi guys,

I started this thread because of my interest in the Lazer. Back then I didn't think that there were many people with the same interest, maybe just a handful. At first I thought there would be a few guys, mostly the collector type who would talk about restoring an old Lazer but I was really surprised to see that there are many of you who are still actively racing the Lazer.

Please don't give up on this thread only because it is slow. It is guys like you who are able to keep it alive. In fact, if you noticed the thread has gone on to 8 pages. Thats more than some others dedicated to more recently available touring kits. So you could see that the thread is quite strong.

One thing is for certain that we all agree on, is that the Lazer was a great 4WD offroader that is far more durable than the current offerings in this class. Also, if it weren't for the failure of Kyosho to market this product properly, the Lazer would still be viable product and a major contender for 4WD IFMAR title.

So keep up the interest and perhaps Kyosho may listen to our enthusiasm on this thread and bring back the Lazer:)

[Lazerfan1]

Bravo Zulo! Great comments! I would really like to see Kyosho release the New Lazer that they just raced in the world Nationals! It looks like an awsome car with some pretty new innovations. Since I'm in the Navy I will be traveling to Japan in the next year comming and I pray to the great Kyoshyo Gods that I will be able to pick up the New Lazer! Or maby they will just finally release it to the american public and at a reasonable price that will be around its competitiors prices! So to those of you who still have a Lazer RACE ON!!!!!!!! and Lets Kick some Losi ***!!!!!

[welshy40]

Wahey - finally some one is out there, cant fault whats been said either. Lazerfan1 - the chance of getting the ZX-S is zero as the only way you can get it is by ordering it in a Japanese shop and then Kyosho get the order and then they build it - daft isnt it - the only car that beat Masami in the Japanese nationals and they never sold it in the UK - boohoo. However, there is a prototype out there, the front is belt drive, but the rear is a direct gear drive. It is said that it cannot handle anything more than a 15d due to the gear box not being able to withstand any more power - so I doubt if you will see it on the market when in Japan.

Have you checked out my machine yet, as per the link on my previous mails? I have attached a picture of the prototype for you to see what I mean.

[Lazerfan1]

Welshy40, I can't believe that this new lazer can only handle the power of a 15d! Just due to the rear being direct drive but it makes me wonder how they intend to fix this little problem. I believe that they should have taken the KX-1 chassi and drive train to the next level and midified it to be the next off road 4-wheeler. Just like Losi did! I bbeleive that the only reason for this indicision was that I was not in Charge! HA-HA-HA. Just kidding! I did check out your wonderful looking machine and it looks like the one that was for sale on e-bay just a couple of days ago, I can tell you have put a lot of work into you Lazer! It looks like a piece of art. I wish I could get mey hands on the chassi and top plate that you have. Later on for now!!!!!!! and Race on.

[welshy40]

Lazerfan 1 - My lazer is one of two ever made, so most definately not anything like what was on Ebay. However I did design the first tub chassis for the Lazer and owned the first one. My lazer chassis/top deck and front mount are my own design, and designed with the batteries further towards the centre of the chassis and to fit into the Lazer zx-s bodyshell (which I have, and is being sprayed as we talk) When I get a chance I will post a picture when its done.

There are more development pieces on my car than you can see, the steering, the slipper etc

[welshy40]

You can get a chassis and top plate like mine - I designed them

[Lazerfan1]

Ok if you designed this wonderful chassi then how much will it cost me to have you make me one and send it to the states? I really want one. How much in US dollars? and what do you thhink abnout my idea about converting the KX-1 into a off road machine? OR is it possible? weather it is or not it is an interseting concept, do you think? Let me know what you think on this issue. It is too bad that they do not produce the KX-1 anymore :( but that is how Kyosho bounces> Later. Ken

[welshy40]

Lazerfan1 - Well I think the chassis is £50.00, and the top deck is £12.00. But I have got to try mine out first as I think two of the holes may be fractionally out on the chassis and the top deck needs adjusting as well, as I may shorten it fractionally to give more play in the front belt (this makes the car run more efficiently).

All the chassis and top deck are countersunk, but may change the top deck end holes back to normal.

If you need any advice just ask.

[welshy40]

Guys,

Here it is, just got the shell and decided to post it, its all brand new, and I have enough new spares to build 3 more like it.

Let me know what you think

[Micha_MX4]

excellent paintjob!

BTW what's the difference between your chassis and the one from FibreLyte, Welchy?

Micha

[Lazerfan1]

That is an awsome paintjob. I wish I could paint that good! Keep up the good work!!!! And Kick some Losi XXX4 ***!!!!!!!!! :ater......

[welshy40]

Micha - the origional fibre-lyte tub chassis was my design - if any one else says that they have the origional chassis and it has no battery holes cut out of it then they are lying. I came up with the design, and Fibre-lyte built it.

The chassis on my car (pictured) is based on the tub with the batt holes 5mm further forwards than the origional ZX, and also 5mm further inwards towards the centre. I also had the excess cut off making it narrower so it could fit into the ZX-S bodyshell. Fibre - Lyte built it for me, but as alway the design is under my name in my file. Check out my RC10 link on the previous mails above somewhere, you can see the chassis pictures.

The Top deck is designed around the ZX-R but I have made it narrower and redesigned the look of it, plus all the holes are countersunk. I had two of the holes where the steering goes filled in (I use steering poles where the top had E clips at the top so no screws are needed.)

The gearbox brace is carbon fibre, as well as the steering arm (ZX not ZXR, as the ZX gives no bump steer), and the servo holder, all of which I had to send the origionals to FL to get them made up.

The front shock mount uses the same holes as the ZX-R, but I redesigned it to look like the ZX-S, and countersunk the screw holes, also I cut off the lump on the front casing and lowered the bottom brace on the shock mount.

The rear of the front gearbox has been cut away and the left and right sides are the only remaining parts of the front gearbox back part remaining.

The rear shock mount i just had the screw holes counter sunk.

The rear gearbox, I only cut away the section where the front belt come out so there is nothing touching it at all. I also removed the brass bushings from the gearboxes making the belts freely move.

The front steering is from another Kyosho car (some nitro car), and this is used on the ZX-S, its higher than the ZX and ZX-R and stops all bump steer with the ZX steering brace.

The layshaft and slipper are what is on the ZX-S, and has an identical design to the RC10B2 slipper system, 2 screws hold the spur gear on, and is far easier to work with.

I use associated ball joints all over for ease of rebuilds.

The front castor blocks are 7.5 degrees and makes the car steer tight into and out of corners at speed. They are ballraced as well making the steering smoother and faster.

The shocks are Traxxas TRX1 shocks and still are the best ever made. I can use heavier oils and makes the car smooth over all surfaces.

The wishbone braces at the front are as the instructions, but the rear one is upside down giving the rear wishbones some angle making the car better on jumps and bumps and helping the rear end to always follow the front.

I hope this helps. Any questions just ask.

[welshy40]

Oh yes I forgot.

The standard universal Joint driveshafts are W5061, which are used by most all around.

By the W5063 which is 3mm longer and put on the front. The W5061 should only be used for the rear.

Has any one ever wondered why there were two holes on the bottom of the castor block?

Well the furthest hole which is in the instructions is for the W5061.

The innner hole is for the W5063 which makes the car more drivable in the rough and bumpy surfaces. It also make the car more tunable to all surfaces including carpet racing, where you can dial it to oversteer without ever having the back end slide out. the back will always follow the front (it got me 5th in the BRCA Indoor British Carpet Finals).

Team Kyosho world wide used this (and me) when the car was released up until it stopped being made. A worthy investment.

[Lazerfan1]

Hey I really appriciate this information about the drive shafts since both of my front drive shafts broke last night going over a jump! I will be ordering them soon! One more question> I was wondering about how to get the new toplayshaft that you have so that I could put it into this old Lazer ZXR and get rid of this existing one so that I would be able to run different Gear ratios. Since I'm stuck with this 100t spur and 20 tooth pinion gear ratio and I'm unable to find existing spurgears that are in different sizes and able to fit this slipper design. It is the set up that has the 2 red slipper pads on both sides and is Keyed to the Spur gear itself! Do you have one that I would be able to get from you? Also what type of gear ratio and motor combo do you use that beat Massiam down the straightaway???? One more thing you said that the slipper clutch design is the same at the RC10B2 correct! Did you ever try the Robinsions Lightened Slipper clutch in order to reduce the rotating mass on the car? If you did it could add that little bit of extra acceleration that you could be looking for when you come out of the corners or even down the straightaways! Later,!

[welshy40]

Lazerfan1 - right the only layshaft you should be using is the standard - forget the other manufacturers lightend stuff, as its not as good as the origional - I have tried all and none are good. You need the one way to get the car to supreme handling, accelaration difference is not noticable.

Z-K/LAW12 Hyper Clutch Lazer ZX-RR (its a whole new designed unit with exception of the one way which you do not get) £53.50 (uk pounds) it was only brought in for the Team, so never got sold, so they should still have a few at - www.Ripmax.com - but be warned I think the only way to get anything is to ring them up (mon to fri 9.30 to 4.30). Check out the web site for their number or email if they have one, otherwise you could send me the money and I could get you it.

Also the slipper pads are available at tower hobbies, but will only be for the hyper clutch. I will have the part numbers within 4 weeks as I am waiting for the part number as its in the post.

How many 100t spurs do you have?? As im in serious need for one.

What other gears do you use, as the only one I can use is a 98 schumacher, but only after modifying. I havent tried a kimbrough 96, but I guess it should fit.

You should at least run the slipper with a fraction of slip not too much. And of course the one way loose.

I used a 13 double against Masami Hirosaka with a 100t and a 23 tooth pinion, and my friend spent 4 hours preparing the motor so it sipped the battery power, but went like a rocket. It was so torquey that I could, and probably did gear up because it just accelarated like it had a rocket attached it.

I normally run a 10double with 100t and 19 or 20 pinion, all depends on the make of motor.

[Lazerfan1]

When I get home after work tonight I will dig deep into my box of old parts to find out how many 100t spur gears that I have and If you e-mail me your address at Rcgeico I will send out what I have to you and thanks for the part numbers on that slipper clutch. If I get this slipper clutch will I be able to use my existing top shaft and My existing 1-way that I already have on there? Because I know that there are two lenghts of these top shafts and I have both of them because I got the other top shaft off of a standard Lazer zx that I bought used for parts. I will look up Ripmax and see if they have these clutches. I'm hoping for the best. Later!!!

[welshy40]

Lazerfan1 - the hyperclutch is the layshaft, the back and front part with slipper pad in between, the coil slipper spring and a thrust bearing with two washer pads, and the spur gear bearing. And a couple of little bits and bobs as well. It looks superb when you build it.

You can totally remove your whole slipper system as this replaces it including the layshaft, but the only thing you need to keep on your car is the one way (ZX or ZXR whatever one you have).

You said two lengths?? The lengths are the same, the only difference between the ZX, ZXR, ZXRR and this one is there are different flat spots in different places, but the lengths should all be the same. Other than that they are all different from one another.

I forgot - the times I gave you are UK times for Ripmax, the web site isnt clever, and I dont think you can order on line.

Try and work out when 9.30 to 4.30 is if you do ring, otherwise im more than happy to help out.

[welshy40]

Does any one on this ZX site have any front gearboxes they want to sell me. If its not being used any more get in contact and i will buy it.

[YR4Dude]

I found some on E-bay last year. Just look around and you might get lucky like I did.

BTW have you any experience with the reverse oneway unit on the top shaft?

Please advise.

[welshy40]

YR4Dude - No I havent, the reverse one way sounds like it makes the car totally 4wd, and makes the car 50/50 instead of 60/40, but if it is true then the one way on it would make it interesting.

I have had a solid layshaft for a couple of events, but found the car slower in and out of the corners, as I didnt have a one way on it, so went back to the standard Kyosho unit with a standard 60/40 one way. If it was 50/50 it may be slightly quicker.

Why?? It sounds interesting, so give the info.

Is there some available and if so where??

[welshy40]

The below was on the second page, and thought it was amusing, as the car pictured is a Lazer ZX-S not an R. The R had the crappy ZXR shell, as the Zx-s Shell is narrower and the chassis wont fit into it.




From the looks of it >>>


and don't hold me to this, but I think it was a version sold only in Europe and Asia...basically a team modified ZX-R. I remembering hearing that it had a more optimized chassis, thinner belts, different shock towers, hard-anodized shocks the usual factory race team goodies

Also just for your info, the graphite wishbones aren't stronger than the origional wishbones, they are lighter. The origional were Kevlar reinforced plastic (bullet proof material) and are stronger than Graphite reinforced.

[welshy40]

YR4Dude - I understand now - the reverse one way is actually the item that goes on a Lazer ZX (its part of the 3rd diff - the back section that the spur sits on, and goes into the gearbox on the layshaft).

It means the bearing is the other way around but rotates the same way as the one way - or makes the layshaft rotate. It makes no difference compared to the ZXR system, which did away the third diff. It just means when you reverse you only have the rear wheels moving under power. Its heavier than the ZXR, and worth changing as it does nothing without the third diff, as its based around the diff technology.

I hope I made sense.

[welshy40]

Micha_MX4 - Im going to get some CVD's and wanted to know about the 57453 GP10 ones you got. You said they were an identical length to the standard ZXR driveshafts (W5061) Yes?? or are they the longer Lazer driveshafts W5063) ??

You see the front can be widened, as all team drivers did this using the second hole on the castor block and wider shafts, which made the car more stable. I have always, since day one had them.

Also is the front section identical to the shape of the normal shafts, so the hex nuts will lock on ??

[welshy40]

.:confused: :( :( :confused: :mad:

[welshy40]

:( :confused: :mad:

[welshy40]

This site needs a major refurbishment, its a joke at the moment, I cant place pictures more than once - daft isnt it, and you cannot delete if you make a mistake - evan more stupid than the first. Im not happy using this site.

[welshy40]

:confused:

I know I have already asked, but Im gonna keep trying. I need one of these, is there any one who wants to sell me one?? If you are not using it any more then give it to a good home (mine), as I will be unable to race a speed without it.

[welshy40]

Right I have calmed down now. Look guys, I have added a few links here for stock in Tower Hobbies, it may and may not make sense, but contact me and will discuss. these items are for our cars, and there is a lot of other stuff, but these dont stand out easily. The steering everyone who has a Lazer needs this...as it gets rid of all bumpsteer, and is the same as on the ZX-S. I use it and is better than standard.

[Micha_MX4]

the MIP CVD have the same length...

I widened the rear to the max as you see in the pics I posted...

Micha

[welshy40]

Micha_MX4 - yes but does this mean that the origional driveshafts were the standard kit ones W5061 or the 3mm longer ones W5063?

[welshy40]

Lazerfan1 - look on page 3 and you will see the slipper clutch Hyper drive. That is what I beleive Ripmax have in stock

[Lazerfan1]

Yes that is exactly what I need! Thanks now I tried to call Ripmax and there was just no getting thru to them. SO Can I buy one of you Clutch systems? How much? and also will I be able to use the existing top shaft that I have right now? Oh by the way I have only one 1 100t spurgear I found uin the box of parts but some of the teeth on it are starting to flatten! Sorry that I can't help you in this department! Oh and thanks for the great list of parts that you posted! My wife is gettint frustrated with me and all thwe parts that I want to buy for my Lazer!!!! Oh well that is how the Cookie crumbles!!!

[Micha_MX4]

when I swaped the original drivshafts with
the CVD's the front were longer, that's what I posted.

I wrote that I could use the front length CVD's only 'coz I used the aluminum rear hub carrier .

rhe GP10 CVD's are the same length as the front Lazer ZX-R driveshafts.

Micha

[YR4Dude]

Welshey,

Are you saying that I could use bits from my Kyosho TF-4R to improve the handling of my ZXR?

Could I use the front hub carrier from the TF-4R with the 3mm longer shafts you mentioned to get a wider front end?

Also, you listed a TF-4R rear hub, could this also be used to widen the rear end again with the same drive shafts?

One last thing, my cars are equiped with the old Gold shocks. They were good during its time but are there better ones out there? Would the new Kyosho units be better? I have heard the Losi ones work very well also. What is your preference?

[welshy40]

Lazerfan1 - the hyperclutch is a whole unit including the layshaft which is totally different from what you are using. I put the price on either page 8 or 9. I will contact Ripmax and see if they have stock. Check out what I said earlier, Micha posted the instructions for his shocks, where there is also the Hyperclutch unit, have a look.

YR4Dude - Im saying that the castor blocks that are with the Lazer have two holes at the bottom (where the castor block connects to the wishbone), the outer hole is whats on the instructions to be used, but the inner hole is the one im using with 3mm longer driveshafts (W5063). This makes the car more stable and alters the handling (it makes it better in and out of the corners). I use the 7 degree blocks for the Lazer, and the hole that pushes the front end out more. I will post some pics when I can.

The rear hubs are what were used on the ZX-S as well, and it uses the same driveshafts (W5061 Rear), so I think that they could be used on our Lazers as well. Im going to get a pair and see, but they look like they will work and be the same width as the origional set. It looks better and has more settings to play with. Try the TF4 part and see if it fits, and the width doesnt change then hey presto we are onto a winner.

The steering however is the item you do need, as this cancels out the bump steer due to being about 3 to 4mm higher. It a must.

Shocks - well the ZXRR shocks were rubbish (the evolution shocks that Micha posted the instructions on), I hated them, mind you Ellis Stafford won a Euros with a set of them so are quite good. But I wasnt keen on the materials used, and the build quality. I rekon a better bet is either using Losi, or Associated shocks - whatever turns you on more between those two.

The items I put from towers are what I could make work on my car and with a bit of imagination everyone could. I just put them on just because they arent always thought of by Lazer drivers and worth mentioning.

I hope I make sense.

[welshy40]

YR4Dude - This is the hole i was on about on the castor block

[welshy40]

Has any one got an MIP diff kit, where you can use associated parts?? If so can you dismantle one diff and take a picture of the changed parts, and post them. I need this as a reference to get it made up over here. Unless someone can get an email address from MIP.

Welshy40 I just went to the Mip webpage and ther was only this phone # thru out the website and no e-mail address in order to contact them. Good luck is you can contact them then maby they can send you a picture of what you need! Later. Oh I'm tyring something I bought a Traxxass spur gear yesterday and it came with a bushing that is approximatily 1mm larger than the top shaft and approxitmatily 3 mm too thick. I'm going to take it to work and see if one of the machinist will be able to to make fabricate me a bronse bushing that will be the same diameter on the outside to fit the traxxas spur gear and the same size as the top shaft itself and then I will be able to use any size trazxxas spur gears all day long with my existing slipper set up or wben the other slipper set up that uses the diff balls and the diff rings! wish me luck and I hope this works, if it does then I will have an endless supply of cheap spur gears that only cost 3.00 apiece!!!!

[welshy40]

YR4Dude - if you still prefer the origional gold shocks just put blue mip seals in the shocks and you will notice the change. Also I have a good set of gold shocks that I no longer require, and would happily trade them for either the MIP diff kit (the parts that make the associated bits fit in the Lazer diff) or the LA31 Upper deck mount - the motor / heatsink section but in metal (as per the picture I attached on page 9).

Lazerfan 1 - you also have another option. Why not get some Kimbrough spurs, or schumacher 98 spurs, and take the front metal part of your slipper off the car, and have two holes drilled in the correct places so you can screw the spur (whatever make you choose) on to the clutch and when built you can change gears without altering the clutch settings. Good luck any way.

[Lazerfan1]

That is a great idea for the slipper so that i may use any gear choice that I wish and it is a great way not to alter theslipper setting. Thanks again!

[welshy40]

Lazerfan1 - no probs, just remember though, that the Hyperclutch is pricey but is still available in the UK. However I have another idea that could be much simpler than doing all that. I think this will fit (I hope anyway, as I have ordered one)

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXVL59&P=7

This would be easier, but you may need the thrust bearings as well for it, as well as a bearing to fit in the centre.

YR4Dude - The Kyosho Linkage Stoppers I listed earlier, I have an idea and when you look at the wishbones on the Lazer you will notice that there is a section on the wishbones (where the rod goes through on the chassis), that is designed for that, to stop the wishbones moving, and then no spacers will be required. Seeing as the wishbone holders are no more, I am going to design something and use the stoppers to stop movement. What do you think?

[welshy40]

Lazerfan1 - Oh sorry I forgot to answer about the KX1 conversion idea.

I dont think its going to be a good idea, mainly due to it being a single belt, so a permanent 4wd wont be drastically good on the corners (60/40 is better especially with a one way). It could be done quite easily though to make it into a 4wd.

Im contemplating getting some flat graphite pieces being made up to replace the wishbone holders (if they ever break), so with the linkage stoppers I can do it.

How much do you reckon I could sell my lazer for (if I ever decide to)??

[Lazerfan1]

#1 Question is why would you even contemplate on thinking of selling such a wonderful machine? And is you did think about it then I would start the bidding at a Miniumn of $500.00 on E-bay and see what it could possibly go for! Just looking at everything that you have into it and knowing what this car is capable of is worth evey cent that someone like me would buy it for if I could begin to afford it! I also think that the KX-1 had a 1-way front diff and I think that the single belt drive system would be great just like the XXX4 if you could possibly add a slipperclutch to the drivetrain! The thought of this is very entertaining is it not??? If you were to sell your Lazer then what would you drive next??? A Schumacher, Yokomo YR4 SuperDog Fighter or the New Durango or the BJ4x4??? OR are you going to retire from the hobby?? Later from Ken.............

[Micha_MX4]

definitely you should go for a Yokomo:

MR4-BC Special :) or

MX-4 like me... :D

http://mike-high.bei.t-online.de/pictures/yokomo/alu-cvd_caps/IMG_0539.JPG

http://mike-high.bei.t-online.de/pictures/yokomo/alu-cvd_caps/IMG_0542.JPG

;)

BTW the shocks are BC-Special, MIP alu CVD'S Fibrelyte carbon, Lunsford Ti and AE Ti turnbuckles....

Micha

[Lazerfan1]

MICHA THAT IS AN AWSOME LOOKING BUGGY! SO THAT IS THE OLD MX-4 CORRECT? SO HOW DOES IT RUN AGAINST THE NEW XXX4 BUGGIES? AND HOW DOES IT COMPARE WITH THE NEW YOKOMO MR4BC? IF I'M CORRECT MASSIAMI H USED IT TO WIN THE WORLDS A FEW YEARS AGO DIDN'T HE? I WOULD LOVE TO SEE A SHOWDOWN BETWEEN YOUR CAR AND WELSHY-40'S LAZER! IT WOULD BE AN INTERESTING RACE I WOULD BELIEVE! AND ACTUALLY CATCH THIS RACE ON TAPE ALSO! DON'T YOU THINK? LATER FROM KEN.............

[Micha_MX4]

well it's sexy...

about the same league as the MR4-BC Sp2

-> kicks XXX-4 butts

http://mike-high.bei.t-online.de/pictures/yokomo/outdoor2/Unbenannt-5.jpg

I don't want to overdo it with Yok pics, but this is one of my favorites...

Micha

BTW... I think the MX-4 is more competitive than any lazer 'coz of the lower COG.

[dave56bug]

Anyone seen this?

http://www.ripmax.com/ProductFrames/C-K30191RSE.html


Kyosho Zaboon, shaft drive 4wd buggy?

Stupid sounding name, but it looks kinda neat.

Dave.

[Lazerfan1]

The Zaboon looks like the Alpha series car with a couple of off road shocks,tires,and body on it! But it still comes stock with the bronze bushings and stock motor and speed control and radio buying this car is probly strictly for the entry level person getting into 4-wheel drive! Not a bad investment for bashing around the backyard but not for the track, but that is just my personal appion> does anybody else share this same feeling about this car? Micha you have a beautiful peice of machinery there and I', glad to here that it kicks XXX4 buts around the track!!! SO what motor and gearing and speed controll do you use? Just curious. Hey what do you think about turnng a KX-1 into a 4-wheel offroader with the single belt drive just like the XXX4 with the inclusion of the slipperclutch? what is your oppion on this interesting concept? Later...............

[welshy40]

Micha - Very nice.

Lazerfan 1 - The Yok against my Lazer hmmmm, well the lower centre of G wouldnt make much of a difference, considering there isnt that much higher than the Yok, but I think the Lazer could keep up easily, if not beat it (especially down the straight). I found the Lazer was superior on high grip surfaces, and on rutty and rough tracks than anything else, and oh yes and the rain (Masami H knows what I mean).

My Lazer - well Im considering calling it a day, I havent decided properly yet, but am considering everything. Im thinking of selling every item separately (as all my spares are brand new) as I would get more cash, unless someone offered me a nice sum for everything.

I do however enjoy making everything perfect on it when I have nothing to do, hence why Im going to make the diffs as sweet as an Associated, and all that is needed to finish and make perfect is the aluminium rear chassis gearbox / mount to get the heat awy from the motor.

Did you check the link out at Tower Hobbies? That may be an easier alternative for your spur gear.

The KX1 - well maybe, but I still dont think it would be that good evan with the one way and slipper. I hear that the one way on this car keeps breaking, and thats from someone who drove the car under the Kyosho banner.

Dave56bug - The Zaboon is a heap of junk - dont waste your time. They come ready built, and the quality is like Tamiya (brittle and cheap looking). Its a copy of the TC3 but poorly copied. I have seen this, and wasnt impressed. Evan the Tamiya ready to run kits are far superior and thats saying a lot.
:p

[Lazerfan1]

Welshy40 I checked out the link and to my suprise I already have that spare clutch system these are the same clutches that are used on the Ultima ST and RB and the Evolution GP line of cars and they do not fit my topshaft at all with the existing setup that I currently have! Thanks though! So I will give my orignial idea a try and see if my machinest will be able to fabricate me some sort of bearing here in the next week or so! So how much for one of your extra Hyperclutch sets? IF my machinest doesnot work out?

[dave56bug]

You know, i've owned numerous Tamiya kits, and not one has been brittle, nor cheap, hmm. Its true their buggies arent up to race standards, seeing as they are primarily basher buggies.

Though the new Gravel Hound looks pretty cool, and hopefully they will release a TRF model with more options.

I only posted the link above, because the Lazers are no longer available, and even ones on ebay are selling for way too much money, I thought maybe the Zaboon could be a valid alternative. Upon closer inspection of the photos I see that the Zaboon is really lame looking. The suspension looks lacklustre.

Dave.

actually I don't race 'coz there are no tracks here around - everyone is racing 1/8th buggies (two permanent race tracks) .

Motor GM Evo 3 13 T and Evo 4 12T
Trinity D5 11T single, 12T single
Reedy Krypton 10T double

ESc Keyence Infinity A01b (very nice 16 Mos Fets!)

GP3300 pushed matched


I don't know the KX-1 so good to rate the conversion but I know that the belt runs
under the chassis that may be difficult in offroad...

The new Prototype Kyosho is interesting...
8th scale type front suspension, weird rear gearing with a funny black think in the drivetrain torque sensing? or just a clutch?

Micha - I posted a picture on page 8 or 9 with the prototype 4wd Kyosho, it cannot handle powerful motors yet, as the gearbox cannot take the power. The black thing - I will let you know when I find out.

Lazerfan1 - the hyperclutch is roughly 56 pounds and thats including postage to my door, then you have to include the postage to your house, so its a bit pricey.

Dave56bug - tamiya compared to any other manufacturer (with exception of Ttech) are the easiest cars to break - hence why I say brittle, and the gearboxes cannot handle very fast motors as the gearboxes melt (I have done that).

The Lazer ZX/ZXR/ZXRR is no longer available, but the ZX-S is apparantly still being made in small numbers in Japan, and the new Lazer prototype when they sort out all the problems then there will be another.

Micha - the black thing is a one way, the slipper is on the other side, and is similar to the ZXRR hyperclutch design. The shocks aren't 1/8th, they are normal size, just redesigned slightly, due to it being a prototype.

The ZXRR evolution shocks were rubbish, so maybe they are developing new ones.

But they are not as big as the Traxxas big bore shocks. Chech out page 8 where I included the picture and you will see the shocks are the same design as the evolution ZXRR ones.

I meant the upper A-Arm design of the front suspension is like 8th scale
not the size but the type...

[welshy40]

Micha - the arms look very much like what was on the 1/10th TR15, and of course the design is copied from Yokomo, but I havent seen it on a 1/8th car, and I owned an inferno 7.5 a while back.

Hey Welshy-40 I have a Navy Machiniest working on a couple of my parts and I'm going to see if he will machine me a duplicate of my A&L Alumin motor mount and the subchassi mount and the top plate and the chassi and the chassi plate also and even the suspension arms! He said it will take him a few weeks to do this but when he does this I will post pictures and show you this wonderful project that I'm working on. It should be a rolling tank after I get done. After that I just may have to go brushless after this just in order to move the car but who knows? Hey if he make me the doubles of the rear Subchassi mount and the motorplate will you consider a trade for the hyperclutch system? if this sounds like a good trade to you let me know! OK :)

[Lazerfan1]

Oh one more thing here is my web page for anyone to see it only has my X-mod and My Lazer so go ahead and check it out at www.picturetrail.com/RCfan1.

Lazerfan1 - Nice car - well I cant trade you a hyperclutch as the price is more than I can afford, but I can do a good trade though. I can supply you with a front shock mount that I doubt you will break (I will post a picture when I can) and a rear shock mount made out of graphite/Carbon Fibre. Its stronger and lighter and looks better, as you have seen on my car. I may also be able to get you an L brace and a steering brace as well as the servo mount all in the same material.

I wouldnt bother with metal wishbones as they can do more damage, as when they break they dont snap, but bend and this breaks more things on the chassis - I have done this once when I was trying them out when they first came out.

The only metal items i am after is on page 9 (I think) and its the top deck holder in front of the motor with the three big screw holes, and the motor mount that you are using.

I do have a few pointers though for you for your car.

1. Change all the ball joints you have to associated, metal balls and plastic ball joints - I think yours are RPM or Losi, and they are not as good.

2. Get the 3mm longer front driveshafts and use the other hole on your front castor blocks to make the front wider, and also use the degree angle as yours is 0 (instruction setting - the outer hole on castor block).

3. You do realise that the rear wishbones are on backwards, if you didnt, swap them around.

4. The steering needs to be changed to the blue items that Tower sell (On that list I posted), and make sure you are using the ZX steering brace.

5. Check your camber, it doesnt look right.

Its a ZX isnt it?? Not a ZXR. The shock mounts are ZX. If its a ZXR what one is it. MK1? Mk2? I cant make out on the pics which one as you have modified the L brace so am not sure. Also I need to check out the spur gear, and slipper, do you have a picture?

[Lazerfan1]

Welshy40, well let me tell you that when I got this car it started out as a ZX Sport with the plastic chassi and the bronze bushings and the steel geared differentials and plastic shocks and steel turnbuckles and stock ball ends with those big huge palstic ball cups open on both sides. Then slowly but surley I kept buying parts from this guy in Austrualia and he told me that what you see were the parts from a ZXR which ended up being the Chassi and top plate and the front and rearball differentials, full ball bearings and the front and rear universial drive shafts and the front suspension arms and the slipperclutch system with the one way top shaft bearing. Since then as you can see I added the A&L front and rear shock towers and the front and rear alumin suspension arm mounts, adn motor heat sink also from A&L and the front A&L Chassi deck support for the front. Then the Dubro 3mm ball ends with the Dubro ball cups all the way around. withe the TT steel turnbuckles. ALso the front alumin hub carrier with Ball bearings and the front alumin knuckles from an old Beagle. so as you can tell I have completley rebuilt the car from the ground up! Also the guy I bought the parts from sent me a photo copy of the instructions of the ZXR that he got the parts from. So tht is the only reason why I call it a ZXR. Oh by the way the rims that I have found for this are by HPI (#3039 Mesh wheel 57x35mm) (2.2 in.) Gold. if you usee this stock number thru tower hobbies then they will come up thru with there current stock number. Oh my L brace above my motor was cut to give me a little bit more clearence above my motor. So I'm really not quite sure wich chassi this guy gave me but I do know that my belt is extremly loose but it runs just fine! Suprising!! Oh the slipppercultch system I will take a better picture when I get the parts back from my friend who is trying to make them out of alumin OK Give me your opion on what you think my car should really be called! Thanks!

[welshy40]

Lazerfan1 - Its a ZX.

I reckon you should get the parts that I have on my car, like two silver bars I have in the centre of my chassis, as this gives you more room on the chassis.

Also the L brace,servo mount, steering brace and both shock mounts from a ZXR are better than the ZX, especially the ones I have. They have more options to dial your car, and it also looks better and is stronger. If the A&L items bends it breaks your front gearbox as well, and trying to get replacements is almost impossible. The carbon fibre shock mounts havent broken on me yet.

If its looks you want as well as performance then the black associated ball joints look superb and do a good job.

But most definately the steering item as it stops all bumps steering and makes the car more driveable and the longer front driveshafts. Once you have all of them then your car should be complete.

Oh yes one more thing, the front belt needs to be stupidly loose, so that you can actually push it through your top deck - the car is more efficient that way, and very free when costing.
