I'm afraid I don't quite understand your comment..Fuel injectors and cleaners? what are you talking about?

[Big boys go fas]

Fuel injectors push fuel in so ur car gets power out a that
fuel cleaner keeps fuel clean

[Lost Racer1]

I understand that part..But for R/C?

[altmaster_1]

i have a stock msx3 and i was wanting hop ups. i am wondering could you tell me where you got all of those hop ups for your car? Thanks

[InsaneRc]

The MSX3 is a great car. My wife and I both have one. I know somethings from the MTX-2 will fit and the the 2 speed from the Prime (K0240). Anyone know of a graphite upper deck?

[Y2KSaInT]

R u guys refering to the Mugen - MSX-3 RTP Nitro Touring Car? Is it worth getting? How fast is it stock? It looks pretty good, but I cant decide between it & the RTR TC3 Nitro. :( I'd really appreciate any feedback on the car please! :) Is there a 2 speed transmission upgrade for it & will HPI bodies & rims fit?

Sorry for all the questions!
THANKS!

[InsaneRc]

Ok last weekend was first race. The car runs great is easy to set up. The car hooks up even with out the 2 speed. The stock motor is fast. If you have radio gear get the regullar kit its completely built except for radio,servos!!

My Hop-Ups
- K0240 2 Speed Transmission
- C0308 Graphite Brake
- MOtorsaver Filter
- GS Ball Cups (The stock one really are a pain)

[PrimeAKF11]

1/8 world champion osaka genji drove his MSX-3 (got that, MSX-3, not MTX-2!) on official mugen seiki cup race couple of weeks ago in korea, and placed 1st :)
there were lots of v1r's and impulses

nice work, MSX

just wanted to let you guys know :)

[cow is GOD!]

does anyone else actually have this car?

[ponky_wonky]

nope, most japanese rc manufactureers dont advertise engough in north amercian and europe, only in asia cause people over there are mad rich
latez

[cow is GOD!]

i have this car and i live in england- grate car tho
90% pre-built comes with decent engine and for only £200!

[Lost Racer1]

I still have mine and I live in the U.S. Great car and lots of fun to race. :) I just have to learn to drive ;)

[Akina'sMtx-2]

This car is a good compition car against the RTR3/SS. We have a project MSX, not completely done yet, but it was built to race against the RS4-3 SS. So far we installed:

Mugen 2 speed
graphite disk brake
Mugen 3 pin light weight flywheel
OS rear exhause header(waiting for the nova engine)
Mugen lowered engine mounts
and Zspeed Hump battery pack

It still have the stock MV12 engine, but it's waiting for a rear exhaust to be droped into it. More mods will be install as we continue to build the car. I will post pic as soon as the car is together...

[Akina'sMtx-2]

Hey insane, post pic of your nice msx, and stop showing off your wifes car. :D

[Lost Racer1]

D you guys know if the MSX and prime 12 share the same shocktowers? I cracked my graphite ones :( I can't find any place that has those parts any more.

Which Mugen 2spd did you use? What clucthbell do you need? Anything "special" you had to do to make the 2 spd fit/work?

I'm looking to get the MSX-3 for my son, but I defenitely want a 2 spd tranny and rear exhaust engine in it.

[cow is GOD!]

when you buy the car from your lhs, ask them to recommend a decent .12 rear exhaust engine for it an ask them for a 2 speed tranny (if they dont have it in stock ask them to order it for you) and it should be a straight drop-in mod without you having to do anything else to the car ---- so easy to do even a newb could do it!
also ask them for a new tuned pipe (preferably c-vec_ and a new manifold so the pipe will fit

[tekrsq]

I've got plenty of rear exhaust engines to put in it, that's not the problem. Just not sure which header the car needs. Also, I wasn't aware there was a 2spd designed specifically for the MX3, I haven't been able to find one listed anywhere. However I did find individual parts listed on the Mugen site. I thought these guys were fitting in a tranny from the MTX-2 and was curious what they had to mod to get it to fit. I do have one of those laying around.

[Lost Racer1]

The MSX3 should use the same one as the prime 12 I believe part number MUGKO240. And to use the rear exhaust you'll need the Ofna Header..I'll see if i can find a part number I bought mine a year ago.

EDIT:Hpi's 2-speed clutchbell will work too. Not sure on the spur..
The MTX-2 one wil fit also??

[Akina'sMtx-2]

Sorry for the late reply. As for the header, we're using OS header, part number k0952. Ofna header will work also. The engien mount are from mugen, part number k071a. The regular 2 speed will work, if the clutch bell is too big, use the mtx one, but most likely, everything will bolt right on.

[Lost Racer1]

For the owners of the MSX3's: Where are you getting your hop ups? My prime 12 is getting harder to find parts for exclusively. So I'm looking for alternative parts :)

[tekrsq]

Thanks Guys!!!

I use to have brand new in bag parts, but sold them not too long ago. I still have a set of prime 12 body post, but Im saving them for the msx.

[Lost Racer1]

I've got the extra body posts:p :D

I mean like graphite shoctowers. Things like that. I had a set and cracked them due to a runaway:( I tried to epoxy them;)

[Lost Racer1]

Does anyone know If HPI cva's will work..Or what would be needed to make them work? I have the mugen ones and destroyed one them. The set pin came out an broke the housing for it. So now I'm running 3 cva's and 1 dogbone. :(

[bigdog302]

i have a prime 12 myself,great car.it has the optional 3 mm chassis,aluminum spurgear mount,mugen tuned pipe set and a novarossi cx 12 engine and 2 speed transmission,it hauls ass.

[No Weak Links !]

I have one and so far real pleased with it ... I race mind at a large oval track and this leads me to this question ... with the 2 speed that i have for it ... who sells Pinion gears for it and or Spur gears at the time my hi gear is a 18P Pinion but i need a 19P..20P.. and a 21P to be able to tune my engine ... at the time she screams more than i like .... any help would be nice
Lance

[Lost Racer1]

I'm not sure if another spur will fit. However if you use an MTX-2 or HPI bell I think you can adjust to different pinions.

[Fogeljazz]

Hi Guys!

I have a Prime 12 and I'm really happy with it. Runs great and I think it out-handles my friends fully tuned kyosho pure ten gp spider, Although his is quicker with two speed gear box
and os engine.
What do you think are the first and most essential hop-ups to get? It's completely stock (except for tires =) ).

[Lost Racer1]

I say a 2 speed and different ballends. I can't remember what they're called, but they will NOT pop off in the event of a crash. It is lie a captured ball end EXCEPT a screw goes threw the ball and openeing..I wish I had a pic to show you. Because it probably sounds confusing..I'll see what I can come up with.

[Fogeljazz]

OK, thx!

I will buy the 2-speed as soon as the weather gets better.
It's still winter here in Sweden =(

[Akina'sMtx-2]

I found some spares for the prime 12. Email me if any of you guys are interested.

new in package:
3 pack shock towers(f/r)
1 pack joint cup
1 pack 15t clutch bell
1 pack spur gear mount
1 pack rear body post

[Needler56]

that's an incredible msx insanerc. i've recently purchased an MSX and it is very fast out of the box. this is my first nitro car and it was overwhelming for me at first. although, the suspension seems to be soft and it dives everywhere i turn. i've been told to put sway bars. any suggestions? btw, would it be cheaper to order through a hobby store or direct to mugen seiki for msx option parts? thanks!:)

[Akina'sMtx-2]

Is anyone interest in New Hpi SS Header and fuel tank? This will be a great hop up for MSX and prime12, I will sell both for cheap, email me if anyone is interested...

[Needler56]

does anyone have any tips on how to tune the factory MV12 engine? and if anyone uses a starter box and what brand because the opening for the fly wheel on the chassis is relatvely small.

[mustangfreak]

Hi I also have a prime 12 and it came stock with only single speed transmission and I would love to have a two speed and there is no one around that sales this car or any mugen cars any more so could anyone tell me where to get hopups thanks.

[Lost Racer1]

www.nitrohouse.com
give them a call

[rckid11]

I'm trading a Duratrax 1/8 axis buggy for a nice prime 12. Is it a good deal? :confused:

[Lost Racer1]

Depends on how much you like the Axis.
I personally love my prime 12. And it runs great.
I don't know the stipulations of your deal, but
if you have any questions don't hestitate to ask. :)

[rckid11]

sorry i havent told you but i'm not trading or getting a prime 12. mostly because it is hard to get parts for. :D

[Needler56]

does anyone put grease on their gears? i know the car is pretty much ready to run, but i opened up the gear box and there seems to be no grease on the gears.

[Lost Racer1]

I tried silicone diff oil once..hehe..I think I'll try some grease. It couldn't hurt.

[Lost Racer1]

For the prime 12 runners:
Have any of you tried using 4 gears instead of the normal 2 within the diff? I say P12 only because it lookse like the MSX3 already has 4. An would you notice a difference between running the 2 extras?

[me9001]

hi does any of u guys who run msx-3's know of a good tuned pipe and manifold to fit our cars. I've been looking for ages but i can't find one thats specifically made for an msx-3. Talking to the guy that runs my lhs the engine is mounted on the other side of the chassis to most cars. But looking around the net i've noticed that hpi's rs4 is the same as an msx-3. Does anyone know if a manifold from one of them is the same. The mounting holes need to be same dimensions. Let me know what u guys think :)

[Lost Racer1]

tmaxx manifold works also.

[me9001]

well since u guys have put pics of ur pride and joys here's a pic of mine

[me9001]

oh well looks like it didn't work

[Lost Racer1]

What did you try doing?

[me9001]

i tried putting up some pics but files sizes are to large i'll have to do some more at a lower res.. when i get time.

[Lost Racer1]

Here is a couple from mine

[Lost Racer1]

and another

[me9001]

is yours an msx-3 or prime 12 it looks different to my msx-3 i'll try to get my pics up tonite ok

[Lost Racer1]

Prime 12 :)

[Needler56]

that's a very impressive looking car lostracer1. where did you get those shock towers and top plate? i want to custom out my shock towers and top plate on my msx to graphite.

[Lost Racer1]

Hobby ETC. (www.hobbyetc.com)
Top Plate and shocktowers.

Purple Threaded shockbodies on ebay.

I HAD graphite shocktowers. Now I hae aluminum ;) there is a reason. One crash and my graphite towers were shot.

[Needler56]

where did you get the graphite parts at?

[Lost Racer1]

I found them on ebay. You'll have to keep an eye out for them..they pop up everyonce in awhile...

[Temjin006]

Can anyone tell me if i can use the msx3 bumper on the prime 12. My plastic bumper is completely destroy and now i need a new 1.

[Lost Racer1]

the part numbers are differen't between the 2. So I can't really give you a definative answer. The MSX3 number is K0452 and the Prime 12 is K0402. Best I can say to do is to get it and try it. Or jsut order the Prime 12 version. They're not too expensive. The Prime 12 one comes with the front and rear bumper.

[Temjin006]

hey Lost Racer1

I just want to know if the chassis you have on your prime 12 is the optional mugen chassis. If so, are the screws countersunk with the chassis. I am have problems with the button screw scratch to the point that I cant get them out because the head is close to gone. Do you have any suggestion for the suspension? I am trying to get the GPM chassis but I am not able to find it online so far.

[Lost Racer1]

Yes. It is the Mugen chassis. It is countersunk as well. :) I tried getting the gpm one as well, but HobbyEtc said they weren't getting it anymore. :( You can try to order it direct..Chin Ngai (http://www.gpmracing.com.hk/car/page/frame_main.html) I dunno if they even have the stuff still available. They have a graphite one too ;).. Just imagine the shipping costs though!!! If you decide to get more info from them let me know..I'd be inclined to get some stuff too. :)

[Temjin006]

Thanks for answering my qutestion Lost Racer1. I m trying to fix up the Prime 12 for street playing. The current stock chassis scratch the ground too easily with the button screws. This well be the car I will use during work when its boring. Does the chassis include screws because I will be getting stainless steel screws and I need to see it has so I can order with some countersunk screws.

[Lost Racer1]

Yes..It comes with all of the mounting screws. Except for the engine mount screws. But you can pick those up just about anywhere. Yeah, the button head screws do drag a lot. I race mine and use it for fun. Its not a bad competitor at all. Have fun!!!

[Temjin006]

I see you got sway bars on your prime 12. Where did you get them?

[Lost Racer1]

ebay. ;) $5. I got most of the stuff about 1 and a half years ago while people were upgrading to MTX's. My prime 12 runs strong So I have no need for a new car. I just put a new body on and will post pics later today. How long have you had the car?

[Temjin006]

Hey Lost Racer1

I got mine last summer as a gift from my uncle so I can start the hobby. After about a month, I got my self a Nitro TC3 kit and a 5 port turbo engine when I m actually going to a track or when we find a place to setup our own track. Now, I m getting my Prime12 back because I needed a on-road that I can drive on the street without worrying too much about breaking stuff and the power. So far I can alumnium front gear box, alum front shock tower, alum c-hub, alum steering kunckle, and my latest upgrade is a Fantom FR12. It should be the same engine you have. I got it on ebay for 80 bucks brand new. I havent even break-in yet. The prime12 should be a excellent basher for me since the new engine got plenty of power for just street playing. I am looking forward for some alum arms and chassis and rear shock tower but I need a credit card.

[Lost Racer1]

Does that gearbox weigh a lot? I don't think I want to add anymore aluminum to mine accept the BB steering.

[Needler56]

does anyone have a rear exhaust engine mounted on their car? if so, how do you get the starter box wheel to grab the flywheel? did you increase the size of the hole on the chassis, or change the size of the engine mounts and/or flywheel?

[Temjin006]

What BB steering?

[Lost Racer1]

http://www.gpmracing.com.hk/catalogue/ca015.jpg

number PM1248

As far as rear exhaust goes..you'll need the shorter engine mounts so the flywheel will dip through the chassis to meet the starter box. You might need ot change fly wheels..try a larger flywheel. I think they're cheaper than the engine mounts..

[Needler56]

when did the prime 12 come out and when did the msx-3 come out? how soon after did they make these aftermarket parts for the prime 12 when it was released?

[Lost Racer1]

Prime 12 was released first. probably about 4-5 years ago. I'm not sure how long it took for the aftermarket to pick up on it. MSX-3 was released earlier this year. It and the prime 12 do sare some parts, but you can tell by looking at the manual. They can both be found on www.mugenseiki.com

[Temjin006]

Hey Lost Racer1

Why dont you just get bearing for the steering instill of getting that set. Just replace the bushing with bearings unless there are no bushing.

The Prime 12 was release first. The MSX3 is an update version of the car with some changes. MSX3 is just to have new suspension design similar to that of the MTX2. It also has a receiver box built onto the upper deck rather then expose design.

[Lost Racer1]

I don't know why I didn't think of that..I'm gonna strip the car again and take a look.

Hey Lost Racer1

How is the BB steering going?

I got a question. In case my spur gears were destroy, will I be able to use HPI gears as replacement?

[Lost Racer1]

Unfortunately it looks like I'll be buying the BB setup. Oh well. At least I know it will work :)

As far as the spur gears go. I don't see why not. I bought a second gear spur for me jsut recently and am looking to put it on. I'll give it a shot tonight and give you results on saturday..:) I don't see why it wouldn't fit. Have you tried removing the pinion gears at all? They seem like they either don't come off or are just on there extremely tight. You can buy them seperately, thats why I ask.

[Temjin006]

The pinion gears are pretty hard to come off with all the threadlock. I havent taken off the pinion gears on my Prime b4 but i have done it on my TC3. Use a wrench or plier that have teeths similar to the gears and another wrench tat is a bit round for the clutch bell. You dont want to flex the clutch bell out of shape.

For the spurs, I dont know if the way the gears from HPI will mount onto the 2 speed's one way bearing hub.

[Temjin006]

Anyone here know how to remove anodize from aluminum parts?

[Lost Racer1]

Oven cleaner should take the anodizing off.

I'm about to order my BB steering...lol..I should be upgrading my servos instead..

[Temjin006]

Anyone here try rebuilding the diffs before. What weight diff oil do you guys use. And about the gear in the diff. Should I put another 2 or is there 4 already inside the prime12? Need to rebuild the whole car once I got all the alum parts.

Hey Lost Racer1, I got some relatives going back to Hong Kong. I ask them to go to Chin Ngai to see if there are any alum parts left in there inventory. The prices should be a bit cheaper in HK then hobbyetc.

:eek: REALLY!?!? Thats sweet!!

I just rebuilt my diffs and added the 2 extra gears with 3000 fluid. It runs very smooth. and coasts VERY well :) I wanna go to HK :( lol

[Needler56]

how do you know what fluid to add? whats the difference between a higher and lower viscosity? will one run smoother, but harder on the gears and vise versa?

[Temjin006]

With thicker oil, there will be lesser diff action compare to a thinner oil. if you want a stiff diff, you can try auto black grease for cv joints. This stuff is really thick.

[Lost Racer1]

My steering assembly is on the way :)

Temjin: Would you mind finding out about the aluminum chassi for me when your fam goes to HK? I was trying to get that and Hobbyetc said they couldn't order it :(. So if you're able to I'd much appreciate it and let me know the price so I can pay you for it.

Thanks

[Temjin006]

Why you want the GPM chassis when u got the mugen one. I already gave them a list but I dont know when I will know but it should be before August 2nd. I really need a chassis right now. When I run the car now, I see sparks from the screws and that is a little scary.

[Lost Racer1]

The GPM one is lighter. And is machined to be lighter in weight. Yeah change out the screws before they grind down too far. :)
The GPM one is counter sunk as well.

[Temjin006]

What one piece exhaust system or even 2 piece system do u guys recommand. I was thinking of getting this Power Racing pipe with manifold but it looked so cheap. I might get the THS exhaust system for the RTR3 and put that on my prime 12. A lot of the others pipes dont really fit with the stupid pressure nipple being on the bottom once u mount it. I was think about the old tmaxx systems but still dont know. Any better suggestion will help.

[Temjin006]

Hey Lost Racer1

Chin Ngai's store is closed. Dont think I ll be getting the stuff.

Closed?? As in out of business?? :(

back to the drawing board

[Temjin006]

I dont know if it's out of business or new station location. I have my relative check.

[Lost Racer1]

Temjin:Any new developments?

I got the steering stuff in yesterday..It looks to be pretty smooth and solid. I'll probably put it on today.

[Temjin006]

Hey Lost Racer1

THey found the store but most of the prime 12 parts are out of stock. They will have to look. About the chassis, I dont know if it is available now. If it is, I ll let you know.

[Lost Racer1]

Thats cool. Thanks.

[Temjin006]

Lost Racer1

Where did you get your turnbuckle set?

[Lost Racer1]

www.hobbyetc.com
They are GPM, so you may be able to get them out of Hong Kong ;)

[tekrsq]

Is the MV12 a standard or SG crank engine? If it's standard, has anyone put an SG engine in a MSX-3? And if so, what's needed?

[Lost Racer1]

I put an MT12 on my Prime 12 once, but I converted it to a standard crank. I've cut the shaft off an SGshaft .21 before and used a normal pilot shaft. I'm not sure how well that would work on a .12 or .15 though.

[tekrsq]

Thanks for the info. I'm trying to work out a trade to get an MSX-3 for my son. It comes with the MV12, but I'd like to put a better engine in it. The problem is, all my "spare" engines are SG cranks. I guess I'll have to look for a standard crank engine.

[Lost Racer1]

The only reason I swithed cranks was becasue I was having a problem finding a nut back then..I don't see why it wouldn't fit;)

[bbb]

Does anybody know where I can pick a counter sunk chassis for the Prime 12? Or does anybody have one for sale? I just picked one of these off ebay and I like the car except for the chassis.

www.mugenracing.com or you can give Nitrohouse (http://www.nitrohouse.com) a call.

[bbb]

I tried Mugen Racing and they said the chassis is discontinued. I'll try Nitrohouse.

[Lost Racer1]

Post if they have it or not..I may just order another one..

[Temjin006]

Hey Lost Racer1

I just want to post a pic of my new body and also the hop up I got in HK. I wasnt about to get another chassis for you because all the parts had to be custom made to order since they dont carry the parts now and my relative didnt want to wait. I was out of town for a while and when I came back there was the blackout in NY so i couldnt post anything.

:( I wanted that chassis and radio tray. :(
Very nice looking car ;) Congratulations on the parts. Now I have to find someone going there soon and bribe them to wait for the parts :)

I just noticed your fantom engine :) Nice choice!!

[Needler56]

how good is the MV12 engine that comes with the MSX3? i ran about 2.5 quarts through it. nowadays, when i do a first run, it runs like a champ, then the second run, it runs like i'm watching a slow motion instant replay. all the parts seem in good shape and i'm getting good compression. what gives? do these stock engines just die out faster?

How does it sound? Do you have a temp gun? Is it running rich? Do you see smoke when running it? Give us a little more to work with here :) Have you tried tuning it?

[Temjin006]

Hey Lost Racer1

I was wondering how many turns u have on you fantom. Havent I a little problem run too hot. I need some kind of reference as in how many I should do.

[Lost Racer1]

What do you have it set at now? I think I'm close to like 3 turns out, maybe less, I'll have to double check. Does it idle well? And what is your top end set to?

[Temjin006]

Right now i have it at stock setting again. Before I think I have about 2 and 3/4 turns out on high end and maybe 1 and 1/4 on the low end. For me top end isnt that important so i lean the low end a bit to give it more power in the beginning. I dont know which setting caused to overheat.

[Lost Racer1]

try your topend at about 3 out. Your lowend is what usually controls your temp. Your'e suppose to tune your topend first and then your lowend. If you're not to worried about topend speed 3 should be fine. Just listen to it when it gets up there. You can hear when it starts to lean out. How is your idle? it doesn't have to idle all day, but at the same time you want to be able to just go. I'll check mine when I get home tonight to see where I'm sitting.

[Needler56]

lostracer,
the engine sounds fine, but sometimes gives off a "crackle" noise, i don't have a temp gun, and i tuned it(i don't remember the exact settings), but nowadays it seems to cut off at those settings, so now i have it back to factory settings. and why is it i can start it easily the first time, but the second time have the hardest time starting it? thanks
(this is off the topic, but does anyone know how to program a Tekin G10 electronic speed control?)

[Needler56]

by the way, i do see a little bit of smoke from the exhaust header

[Lost Racer1]

Needleer: How old is your engine? It sounds like you may need a rebuild..

[Needler56]

lostracer: my engine is about 7 months old. how do i do a rebuild?

[Lost Racer1]

Piston/sleeve/possibly conrod. If you don't have a temp gauge I would highly suggest getting one. It sounds like your sleeve is worn. WHen cold it starts up fine, but after it gets warm it loses compression when the sleeve expands. Thats what sounds like is happening. However I am few thousand miles away, so you might want to double check with some locals first ;)

[Needler56]

lostracer:i took apart my engine and the wrist pin is bent and cracked. there's little cuts on the conrod and the top of the piston(where the pin goes into) has blisters on the top and there are blisters on the bottom of the cylinder head where i guess the piston meets. what caused this? should those blisters be smoothened out? and what's a good temperature gun to get, how much does it cost? thanks

:eek: :eek: :eek: :eek:

Scratches usually mean some kind of debris got in there, dirt, rock any type of particle. Blisters I can only think maybe running too lean. Overall, time for a rebuild. Something either fell into the chamber from the top or was sucked in if you were running with the filter off.. The stock engine is suppose to be ok..rebuilding it however I'm not so sure on the prices. You may be better off just replacing it..
As far as temp reading goes..There are quite a few options out there now, I have a temp gun. Its good because its a bit more accurate than the looped ones. But also cost a bit more.

[Needler56]

you have to pay to get rebuilds done? what exactly is it that they do to it? yeah, i have an rear exhaust MT12 engine, but i haven't had time to get the pipe and i was just fiddling around with the MV12 for now.

[Lost Racer1]

some shops will do it for you. Is not hard at all. Its pretty much just replacing your internals with new pieces. Along with o-rings and gaskets.

[Needler56]

i got an exhaust system for my MT12 and i was wondering how install the muffler stay. and i have a fuel filter, how do i know when to change/clean the filter?
-aaron

[Lost Racer1]

you got an exhaust for the MT12. what do you mean by "How to install the muffler stay"? Do you mean where to mount it?

You should check your filter for build up to determine whether or not it needs to be cleaned. If you notice the fuel not flowing smoothly, that could be a sign.

[Needler56]

i know where to install the muffler stay, i should have been more clear, but do i coil it? what does that do, or is that even necessary?

[Lost Racer1]

you can try to coil it if its too long I guess.I don't think thats really necessary though. Did your pipe come with a setscrew? Maybe I'm misinterpreting what you're trying to say..:(

[Needler56]

so if the fuel filter is dirty, do i clean it with nitro cleaner? when i install it, do i have to increase the length of the fuel tubing? because i've noticed in your pictures that they're longer.

about the muffler stay, yes, it does come with a set screw. i was just wondering if there is a specific way to bend the muffler stay. hopefully when i get my car together i'll post a picture.

[Lost Racer1]

My fuel tubing is long in case of a roll over. I use to running offroad and somethings just stay with me. :) I could probably shorten it a bit. What kind of pipe did you get? Where is the mount point on your pipe? On the tip, top, or bottom? Any way it may be, you'll want to angle the muffler stay up some, so the pipe doesn't scrape. With the fuel filter yes do that..make sure you see all the crap come out of it :)

[Needler56]

heres the url to the pipe i got: http://www.rdlogics.com/store/p_138.htm
if that doesn't work, the website is rdlogics.com, go to rc products then type in "msx3" on the search. it's a rear exhaust set up, dual chamber, chrome, comes with all the necessary hardware. i bought mine at a hobby shop here in silicon valley in california. are you planning on getting a rear exhaust set up?

I grew up in the Silicon Valley:) Thats a nice looking pipe!! I may just have to get one :) I lived in Sunnyvale most of my life...

[Needler56]

hey thanks, how old are you? i lived in sunnyvale for a year with my aunt, i go to sjsu..

[Lost Racer1]

You've been pm'd ;)

[Needler56]

besides the mugen seiki brand, what flywheels and engine mounts out there can fit the msx? nitrohouse said the mugen seiki brand is discontinued and i tried ordering off mugenseiki.com, but no response.

[Lost Racer1]

hmm..engine mounts I've only found mugen ones to work. Most flywheels will work though. I might have a set of stock mounts i you need them. Let me check my box.

[offroadcrazy01]

just drop by to say whats up lost racer long time no see it's me Jay later man

[cduna]

Ok anyone out there with the Mv 12 and 2 speed in their Msx 3 ?

My problem is I cannot get this thing to shift , tried 2 turns out , 3 turns 3 1/2 .. after tearing the 2 speed apart i noticed the finger clutch was chipped a bit arrgh ! But just the same if someone could share what setting they are using on their 2 speed I would appreciate it ..

Thanks I wanna race this thing against my RS4 With the Traxxas 2.5 .. With one gear i know it wont stand a chance !

Chris

[Lost Racer1]

Try 5 out. I think thats where mine is sitting.

[cduna]

5 turns out is a bit much if i turn it that far the pinion actually sticks out and it will get stuck .

Im ordering a new c2 speed clutch thing .

[Lost Racer1]

whoa..ok..You didn't happen to over tighten it at all did you? I did that to my first one and it would never shift. It pushed the little ball out of the opposite side( i was such a newb) :)

C2 clutch thing?? whats that?

[Needler56]

finally, here are pictures of my msx.

[Needler56]

another one.

[Lost Racer1]

Very nice! Hows it running?

[Needler56]

thanks! i haven't had a chance to run it, i've been extra busy with school, but when i run it, i'll let you know. how's your car doing? you know, i took your advice and got a fly wheel that dips through the chassis so the bump start can grab it and it dips about 1mm through. is that gonna be a problem?

[Lost Racer1]

Shouldn't be a problem if your suspension is set up well. ;)

[Needler56]

i have the out-of-the-box set up, it seems to work the best for asphalt running. suppose something did snag on the fly wheel, whats the worst that can happen?

[Lost Racer1]

The engine will stop.

[cduna]

Does anyone know of Cvds , and swaybars that will work on the Msx 3 ? Ive been looking at the Gpm ones for the prime 12 but wasnt sure if they would actully work - the website didnt mention that they did. So just curious if someone knows .. Thanks im trying to find hop ups for my Msx3 any help would be appreciated .

Chris

[Needler56]

for the dog bones and drive axels on my msx, on each side i put a piece of fuel tubing to eliminate the play. now, are you supposed to allow a small amount of play? will making it too tight cause drag?

[cduna]

Play is backlash this you dont want . That is why Im looking for Cvds as I mentioned in my post ..

Here it is if someone can help :

I'm not sure if they'd fit or not. acutally, what I would do is check mugen's website and the part numbers for the stock parts, and see if they match up. Also check the options parts.

[Lost Racer1]

:( It doesn't look promising..

[cduna]

Thanks for you help Lost Racer and Needler ,

I emailed Rc Nitro ( Magazine) They pretty much told me that the prime 12 parts should be interchangable with the Msx3 the only difference's between the 2 is that Prime 12 came as a kit version , Msx 3 RTR. They also mentioned that there might be slight differences between the 2 but the parts I wanted should work out ok . I contacted Mugen and Gpm and neither helped me as much as Rc Nitro . So im going with it if for some reason if the Cvds and Sway bars dont work would one of you guys or someone else be interested in buying them ?

Also who is the best distributor to get Gpm parts from ?

Thanks
Chris :)

[Lost Racer1]

I got my GPM parts from www.Hobbyetc.com

I hope they work out for you..I do know the MSX 3 has 4 spider gears and sealed diffs. I couldn't match up the cvd part numbers though..I had the mugen ones for my prime 12 and shattered 2 :( I hope the gpm ones fit for you..I also heard of someone frankensteining some MIP ones for the HPI and another car..unfortunately he couldn't give me all of the info on i t:(

[Needler56]

lostracer, my car runs like a maniac! but i guess the screws can't handle it and they loosen up. what kind of loctite do i use, the red or the blue bottle? my mine problem is the clutch assembly unloosens even the crankshaft thread.i know that one of them bonds stronger then the other, but what type of application do you use that for? also, what's a good disc brake to get, mine is warped and its causing drag. lastly, what is everyone using for gear grease/differential gear grease? i want to use a grease that will run the gears more loosly with less drag. how do i read the numbers, the higher the number, the looser? or vise versa?

[Lost Racer1]

USE BLUE!!! Leave the red alone!!! Only do metal to metal contacts and never your engine mount screws. I'm not positive on the grease numerology, but if its like oil then the higher the number, the thicker the grease. Just take the red loctite out of your toolbox :) and you should be fine. I should probably change my disk brake as well, I still have the original:p

[Needler56]

yeah, i JUST got some diff gear silicone oil #1000. it goes up to #7000. i got it from rc unlimited in campbell and according to them, the lower the number the thinner and vise versa. hey, have you ever thought about mounting the steering servo onto the chassis for better weight distribution?

[Needler56]

i actually went ahead and shaved down the disk brake with a dremel to flatten it out a bit, just like they do in real life and it actually works!(=

[PrimeAKF11]

cduna,


I've converted my Prime12 to MSX-3 due to part issues, and let me tell you that most of the parts are NOT interchangable.




Lower Chassis and upper deck - they are different, and altho they look similar, MSX-3 chassis does NOT have same screw holes as Prime12 chassis. non-interchangable.

Suspension - ALL suspension parts are not interchangable. Lower arms, front/rear uprights, streeing knuckles.....NONE. Even the Lower arm pins are different.

You can use Prime12 dogbones, diff. cup joints and axle shafts. MSX-3 DOGBONES DIFFER IN DIAMETER AND WILL NOT PAIR UP WITH PRIME12 JOINTS/SHAFTS. If you want to use Prime12 dogbones, you need prime12 joints/shafts.


Center shafts - same rule applies. MSX-3 uses center shafts with different diameters. and MSX-3 center cup joints DO NOT FIT PRIME12 DISC BRAKES.

Front/Rear gear box cases - not interchangable. does not even look similar.


Front/Rear Diffs - Diff cases are different. Prime12 diff cases do not fit in MSX-3 gear box and MSX-3 diff cases will also not fit in Prime12 gear boxes.


Differential Ring gears, bevel gears, and 4 flathead screws that mount ring gears are same between two cars.

also the MSX-3 has 4 bevel gears while Prime12 has 2. MSX-3 has additional parts such as o-rings and gaskets in its differential, allowing the use of silicon fluids.


Front/Rear bumpers, Front/rear shock stays - they are not interchangable at all.


Front Servo Saver/Linkage kit - NOT INTERCHANGABLE.


Throttle Servo Linkage - they are also different.... but you can use them with slight modifications.



Plus, MSX-3 has additional parts that Prime12 doesnt have, such as suspension arm mounts that can be adjusted.





now the parts that are same...

wheels/ wheel adaptors
ALL THE BEARINGS
shocks
fuel tank
linkages
engine mounts
flywheel/clutch/clutch bell components
center transmission parts
dogbones/cup joints (have to go together)
most of the screws (MSX-3 chassis needs flathead screws)


That list seems complete..... I might be missing some tho. As you can see the conversion was a complicated process but I saved $100 compared to just buying new MSX-3 ;) (and my msx-3 still uses Prime12 dogbones/axles/diff cup joints :D )



If anyone need any information regarding which parts are interchangable between two cars, I'll be more than willing to help you out :)

[Lost Racer1]

Hmm..good run down on the list there. Thats a lot of good info. Thanks a lot. I hardly ever see parts for the MSX-3, for me they're about as common as the Prime 12 parts. Do you have any pics of your car? And how much would you say you spent updating it? Oh! The 2 speed is the same as well.

[Needler56]

Do you guys leave some play for the bevel gears that attatch to the main drive shafts? Also, what radios are everyone using? I use an Airtronics Caliber 3PS.

[Needler56]

nevermind, i went ahead and installed some shims.

[No Weak Links !]

If Anyone is interested i have one forsale excellant shape ...if you are interested see the buy/sell forum ..i have pics of it. their

[Needler56]

whats the best disc brake?

[Temjin006]

You can get the mugen fiber disc. One pack comes with two disc. If you want a thicker disc, you can get the hpi one for the rs4s because the shape of the center hole is the same. I prefer you to get the mugen because it's cheaper and you get two.

can I get a part # please?:D my carbon disk from backdrop is getting thinner and thinner....

[Temjin006]

Hey LostRacer,

Do you know if the MSX3 will fit into the Prime12. I want to swap it with a msx3 because that diff can use silicone oil for diff adjustment. If the diff dont fit, do you think the gasket and oring will fit?


Just fitted a tmaxx manifold and a REX pipe on to my Prime 12.

[Needler56]

that z body looks clean! man, i get flexed on by those cars all the time in real life, i don't know why..do you have a picture of the chassis itself?:)

[Temjin006]

Hey Needler,

Just go back a few pages on this forum and you will see my chassis. The car has alum arms f/r, alum shock towers f/r, front alum diff case, two speed, and a countersunk chassis. The car is powered by a Fantom 12FR and I just fitted the engine with a Tmaxx manifold and a REX dual chamber pipe.

This car doesnt come close to my Nitro TC3 that has a Novarossi 5 port but the Prime 12 is way more durable for street use.

[Lost Racer1]

One of the members has gone through thsi one already...The diff parts are not interchangeable :(, however you can try the oring idea...I was thinking the same thing. What rims are those on your Z, thats pretty sick. :D

[Temjin006]

Unfortunately, I alaready put the msx diff house into the prime12. I compare the dimension before i put it in, they the same. The onli difference is the way the bearing are mounted and area allowing the gasket to sit on.

LostRacer, how did you put ur diff oil in your housing. I know I need to put orings on the out drive. But how about gasket in between the diff housing.

The rims came from a Hotbodies Tornado.

[Needler56]

what diff/shock oil wt is everyone using? what's the highest diff/shock wt out there?

[Mugeness]

Hi, does anyone know the default/good setting for tuning the slide carb on the MV12 engine? I bought mine used and it's completely untuned...

Thanks

[Needler56]

(from carb closed) high speed needle is 3.5 turns counter clockwise, low speed needle is 2.5 turns counter clockwise, and idle needle is carb 1mm opened.

after about 10 tanks of running hard(mv12 was my first nitro engine) the conrod snapped, the wrist pin started to crack, and i started to have air leaks.

then i upgraded to a mugen seiki mt12 rear exhaust engine and it was like a dream come true hehe

[Temjin006]

If you said your MT12 was a dream, then my RS12 5 port Novarossi will be heaven. LOL. Maybe it can keep up with my NSR12 5 port Novarossi NTC3on straightaways. I doubt the car will handle as well as my TC3 though.

[Needler56]

LOL!! hey are the MT12 line parts interchangeable with each other?

[Temjin006]

Interchangeable with what? I know the MT12 shares the same carb, head, bearings, button, conrod, wristpin, and maybe piston with the Novarossi RS12 series. The only thing diff might be the crankshaft(timing) and sleeve. My RS12 is cooked after trying to keep up with 8th scales. I am going to send it in to see if they can pinch the sleeve. The process cost 10 bucks. What is there to lose.

[Needler56]

i wanted to put a crankshaft with a "tear drop" port. the mt12 manual also shows the pilot shaft crank with the tear drop port in the exploded view. if i used that particular crank shaft, is there a flywheel/clutch assembly that would be able to mate with the two speed tranny on the drive train?

[Temjin006]

If you use a pilot aka sg shaft, you have to use a cone-like collar and maybe a hpi flywheel. that is the onli way you can use it. I doubt you will gain any noticable power. The turbo crank might be more useful on turbo engine because it crank a bit more air into the engine.

[Mugeness]

Ok, here are some newbie type questions: :)


Firstly, when you said "(from carb closed) high speed needle is 3.5 turns counter clockwise, low speed needle is 2.5 turns counter clockwise, and idle needle is carb 1mm opened."

What does that mean exactly? The needle where to fuel is opened 3.5 turns from completely closed?

And the needle where the linkage is 2.5 turns out from which position? Completely screwed in? Then it seems too much in.. Help :)

Also:


I broke the rear axle that goes into the rear differential.. Do I have to use a Mugen one? Or can I get some other company's that's easier to find? Thanks :)

[Temjin006]

I think you might be able to use those from HPI. You can use any half shaft as long as the length is the same.

[Needler56]

what i meant by carb closed is hold the carb closed and screw in the needle clockwise until you get the first sign of resistance, then thats your starting point.

3.5 turns ccw (counter clockwise) for the hsn (high speed needle)
2.5 turns ccw for the lsn (low speed needle)
1mm open for the idle gear

i didn't know the factory settings so i called mugen seiki and thats what they told me. i hope this helps

btw how did you break the rear axel?

[Mugeness]

I wish I knew how I broke it.. It just.. broke the first time I ran the car.



Just a clarification:

The starting point from when I feel resistence with the carb closed is for the low speed needle that's on the barrel, not the high speed needle that's sticking up, right?

[Needler56]

you do that for all three needles. the purpose of holding down the carb is because if you don't, and you keep on turning, you'll push the carb out not knowing where to stop..

[Mugeness]

Thanks...


Out of curiosity, what do the needles make contact with.. The one on the barrel just seems to hang in mid air

[Needler56]

the needles allow the amount of air/fuel mixture into the carb. turning the needles ccw makes it rich (adding more fuel) and turning it cw makes it lean (adding more air). adding more air adds more rpm's.

[Mugeness]

Any idea which differential axle shaft I can use instead of Mugen's?

It's part K0252 and has been discontinued so I can't even order it through the hobby shop...

I need to know some alternatives...

[Needler56]

did you try nitrohouse.com? they wont have the part listed, but you can call them. they're supposedly (geographically) five miles away from mugen seiki.

other cars that use the two shaft system are the hpi rs4-3 and kyosho fw-05r. i'm not saying that they're interchangeable, but you can try.

for the mean time, you should put the front shaft to the rear so you can try the car rear wheel drive and see how you like it.

[Lost Racer1]

Are you guys still able to get parts for your cars..I'm gonna try nitro house again, but the last time Icalled and told them what car I was looking for parts for, I thought I heard laughter in the background :D

[pauliothegreat]

Hey, im a total newbie to rc cars and i cant find my manual for my car, does anyone have a Mugen MSX3 pdf manual? and also running in instructions as the manual isnt very good if i remember correctly.


Thanks Paul

[NEWguy27]

You guys want hop ups? Keep your eyes on Bell Tech R/C. www.belltechrc.com will be up and running soon with ALOT of Titanium 6al4v (air craft grade ti.) parts! They will be competitive with almost EVERYONE'S price! They are going to huge!

[Needler56]

the car action article on the msx recommends 80wt for the front shocks and 50wt for the rear to balance front and rear traction. i don't understand how this works, wouldn't you want the rear to be stiffer than the front so that when the rear clamps, the front wont lift as much??

also, i ran my car with 1,000wt si in the rear diffs and 5,000wt si in the front diffs, stock caster camber set up, and the mugen seiki 1.9 firm springs (white) layed all the way down, with 40 shore foam tires, and the car handles very aggressively! doesn't sweep out on turns, sticks very well. mugen actually recommends 7,000wt in the front, which i haven't tried yet.

lastly, according to the article, the tamiya ta04 rear stabalizer set (item# 53442) fits on both front and rear on the msx.

[oXoreoXo]

sorry im so late joining this forum.....i got out of the R/C scene for a while...

but did the price for the two speed go down darasticly or something??? i finally just got one off EBAY for 20$... it thought i was crazy or something.

[Needler56]

sorry im so late joining this forum.....i got out of the R/C scene for a while...

but did the price for the two speed go down darasticly or something??? i finally just got one off EBAY for 20$... it thought i was crazy or something.

i had a hobby store order mine and it was $60. the car isn't very popular so that's probably why you got it at that price.

[oXoreoXo]

i was just so shocked because my LHS still sells em for 99$.... but yea ur prob right our car is old. it was hard to find stuff for it when it first came out(i got mine 1st week) but yea is there still any sites that sell anything for our cars???

[oXoreoXo]

old pic of my car

yea come to think of it, at first my lhs told me $90, but they sold it to me at $60 for some reason. its hard to find parts for this car, i don't even think mugen seiki carries any parts. you'd have to go on ebay i guess.

[oXoreoXo]

i dont know if u all have been here but this is the only play i can find any type of reinforcements for the MSX.

http://www.rccarinternational.com/shop/en-us/dept_286.html

[Needler56]

wow, where'd you find that site? btw, what happened to your foam bumper? i ordered parts through mugen seiki a while ago off their old site. i got the mtx-2 springs and shocks, two speed, acadamy rc graphite radio tray and shock towers, and an mt12 engine. i want to post another picture, but i'm having trouble doin so hehe

[oXoreoXo]

it took me a while to find that site(2 hours of looking for stuff for our cars)

i cut the bumper because i bought an HPI elise body and i thought the bumer was in the way when it was really the front shock towers(im an idiot)

how much did that mt12 motor cost you? im thinking about getting one, my neighbors MTX-2 is pretty quick(makes me jealous)

since i have 56k i had to make the pictures significantly smaller to make em upload faster.

[Needler56]

the motor costed $179.99. there are better motors out there, but 1298731297864129846123 people suggested that i get the mt12 and its great. like all motors, if you tune it just right, it'll start every time.

[oXoreoXo]

hey im guessing that academy rc doesnt make the graphite parts for our car anymore? i checked it out and didnt find anything on it.

Any lucky uploading ur pics? i wanna see those graphite parts

[oXoreoXo]

im having some issues with my damn car now :mad: :mad:

im going to assume that its an issue with my radio but if i let my car cruise around it will run fine, the second i go about half opened the car will turn all the way to the right and the throttle open up all the way for about a second.....i dont know what could be causing this. it just started recently and i finally got my 2-speed(20$) and header off the HPI(free) and i cant even open my car up all the way

[Needler56]

i don't know if acadamy rc makes the graphite parts anymore, i got mine off ebay.

as for the picture, i don't have any type of photo shop program to reduce the size of the picture, i'll try to get it up as soon as possible.

is your car having steering or throttle problems?

[Temjin006]

you can use windows' paint program to reduce pics.

As for msx3 parts, i can easily get them from my LHS. I know the store pretty well and I get discount. But I dun have a MSX3, I have the prime12 with all alum parts. the prime12 is a older model and it's discontinue.

[oXoreoXo]

u can use paint by going "view" then "sketch skew" then go like 50% in both fields.....

the problem is kind of both fields for my radio...once i go more then half opened throttle the car just pulls all the way to the right and the radio goes full throttle all the way for about a second...it pisses me off because i finaly got my 2-speed and HPI aluminum header installed but i cant test them out yet....

[Needler56]

k hope this works, the only thing different about this picture and the very first picture i posted in the first few pages of the forum is the graphite parts.

[Needler56]

here's the back, just because this picture came out pretty clear. thanks for your help guys.


oXoreoXo: what kind of servo's are you using and what's their conditions?

[oXoreoXo]

i replaced the origional steering servo with a hi-tec hs-625mg super torque servo because the old ones gears got stripped.... they both seem to be in good conditions still...they dont make any noise or anything when being tested and there are no signs of stress... i dont think its the servos though because it would be wierd if they both started acting up at the same time and stopped at the same time only when running the car

[oXoreoXo]

those graphite parts are sooo damn sexy!!!! i want em..especially since my rear shocktowers snap like twigs constantly. nice job on hangin ur exhaust

[oXoreoXo]

OFNA exhaust
cant remember filter
HPI fiber disc brake
HPI springs
medial pro tires
some ugly rims
2-speed tranny--------------\
HPI aluminum header---------/ NOT IN PICTURE

ohhh and yes my left turnbuckle is broken...meeting with those parking spot things

[bigG]

i buying one of these cars later today and by the looks of things i think i am gonna give the local Ntc3 and rs4 a run for there money as soon as i get my i will post pics and what do u think should be my first up grade other than a 2spd?



thanx

[Needler56]

oreo - are your right front bearings clean? if its dirty, maybe that's whats causing it to veer to the right? hows that hpi fiber disc brake doing for you, does it drop right in?

bigG - the msx is pretty much the same car as the rs4. upgrades are kind of scarce, but what i recommend is putting silicon oil in the diffs and different shock weight in the shocks.

[oXoreoXo]

welcome to the boards bigG...a new airfilter and mid/high speed exhaust are the usual first mods for people, oh yea look into a different header too.

The HPI fiber disc brake had to be modded a little because it is too big to fit between the two screws.

i just took my whole car apart and cleaned it all about a week ago so they should still be clean.

[oXoreoXo]

its been rainning here for the past 3 days so i havent been able to run it either :\ so i havent been able to test it....im thinking it may be my batteries...i realized that i have 4 1.3v batteries from an old toy of mine which i didnt realize so the battery pack in the reciever reads only about 10.7 volts instead of a good 12

[bigG]

ok for air filters i plan on getting a K & N air filter this car fits regular 1/10scale rims and bodies right?


thanx

[oXoreoXo]

hahahaha theres no K&N for RC. i was thinking the same thing when i first started too. Everything from real cars applies the same in 1/10 but on different scales and modding your engine in R/C is alot different then real cars.

but yea...all 1/10 scale rims fit our cars but you want 200MM bodies....there are very few 190mm bodies that fit the msx(altezza is all i know that fits with bumper mods).....id watch bodies with hoods that sit low too...i bought a 200mm lotus elise body from HPI and the hood on the car sits too low and rests on my shock towers

[bigG]

yeah they do make air filter for r/c car look at this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=34063&item=3190837136&rd=1 and i am not that new to r/c cars just nitro


thanx

[bigG]

needler56 has one on page 6 of this thread on his msx3.


thanx

[oXoreoXo]

:eek: BUAWHAHAHAHAHAHHAHA I HAVE NEVER SEEN THIS BEFOR!!!! HAHAHAHAHAHAHHAHA. i stand corrected good sir... i didnt even know there were oil based filters for R/C...i am quite shocked to see this.

[oXoreoXo]

i never paid attention...i just recently got back into r/c again like 2 weeks ago and havent looked into air filters so i had no clue that this existed. but its still hilarious.

how much u picking ur msx up for big?

[bigG]

yeah that y i like nitro cars some much they llike a smaller version of a a race car. This might be a rookie question but i never had a nitro car with a two speed i have only had one with a single speed with a 2spd does the car go faster meaning if ur car
avrange of about 45mph and u install a 2spd will it be fast or what?



thanx

[oXoreoXo]

usually with a 2-speed(depending on how its tuned) u will get a higher top speed and help u get through mid to top end speed alot easier due to the extra gear. so yea it will help alot. since i just got mine last thursday and have been having these problems with my radio and such i havent really been able to test it out..only played with 2-speeds on trucks and stuff

[bigG]

ok thanx i can't wait to get my car and get a 2spd

thanx

[oXoreoXo]

racinghobbies sells a few things for the MSX-3 on ebay....instead of paying 70-100$ at your LHS he has a few for 15$+shipping.

when u picking ur car up?

[bigG]

i am paying for it tonight hopefully it will be shipped tomorrow here is a good place for parts to http://www.lightninghobby.com/store/listCategoriesAndProducts.asp?idCategory=258

thanx

[oXoreoXo]

niiiice...i can pick up another muffler and stuff....been meaning too after my original broke.

[Needler56]

there is a lot of speculation about the k&n air filter, but i can tell you right now, through my experience, that it keeps the engine very clean..but you have to clean the air filter everyday.

i just recently put the stock air filter from hpi savage s-25 engine for maintenance convienience.

bigG - pick up some threadlock. the screws that seem to back out on my car are the set screws for the center drive shafts and the engine mounting screws to the chassis.

[oXoreoXo]

yeaaaa i had the same problem with the screws rattling out...same places too....its cool though when u are drivin down the street at night and u hit a sewer cover and sparks fly ALLLL over the place and later u realize that those were screws from the bottom of ur car that fell apart on the road :P

[oXoreoXo]

hey needler how many turns out do u have on ur 2-speed? mines at half a turn out right now.

[bigG]

hey needler where can i get some of those threadlock?



thanx

[oXoreoXo]

you can pick up threadlock at any hardware store or LHS. loctite and tamiya are the only ones i can think of now that make thread lock

[bigG]

alright i will pick some up later this week. Is the handling on this car good?



thanx

[Needler56]

oreo - i think i need to change the set spring on my two speed because i have it dead bottom clock wise.

bigG - i ran my car with the shocks layed all the way down with the 1.9 white springs (stiff) with the upper arms in the factory position. then i added 1,000 weight in the rear diff and 5,000 weight in the front. the car hugs the ground a lot better than the stock set up and it squares out a lot faster. mugen suggests 7,000 wt in the front diff and 50wt for the rear shocks and 80wt for the front, which i haven't tried yet

[oXoreoXo]

i never put anything in any of my diffs....is that a bad thing?

[Needler56]

greasing the diff gears (like using team associated green slime) reduces friction which means less wear on the diff gears. without anything in the diffs will probably cause your car to sweep on turns.

using silicone oil allows u to select various weights to so you can control the diff action. be aware of how much you fill the diff up, u want a lil over half because the silicone will expand under heat and if you top it off, the diffs will "unload."

i think some of the super cars like the serpents allow you to control the diff action by tightening the diffs.

[oXoreoXo]

aite cool...i think i figured out my problem with my radio system too....i was too lazy to go buy new batteries so i used somoe wierd chinese 1.3v 700mah batteries and in my radio it was only reading like 10.1 so i just replaced the batteries and now its at around 12 so hopefully it should be good

[PaulH]

i think some of the super cars like the serpents allow you to control the diff action by tightening the diffs.

The adjustable diffs are actually ball diffs. Most of the cheaper cars, like the Associated product line, you have to pull the dogbone out of the diff outdrive cup to get at the adjustment screw. Serpent and other "super car" brands put the set screw on a collar around the diff so that you can get to it without disassembling anything.

The really high-end 1/8 cars do not use a diff at all; Instead they have a pair of one-way bearings, one on each outdrive cup, on the front axle, and a solid rear axle. These are harder to drive, but easier to tune, simply because there's one less thing to tune.

[oXoreoXo]

so wait if i put grease on in my diffs then it will help stop my cars back end from going out

is there a way to adjust the diffs on the msx? i never worried about the diffs on my car so i wouldnt know

Associated cars arent cheap (I assume you are talking about the NTC3). If you pay some attention to shaft drive cars with one single shaft, they all use ball diff that require dogbones to come off to adjust the diff. The reason for this is because they have diff cases that cover the diffs. You can look at the trendy single shaft electric cars that is in the market right now. Although they are electric, the drivetrain design is much like that of the NTC3/TC3.

All the race stadium trucks use ball diff too for the adjustability. They also require a dogbone to come off for adjusting the diff. Once again, the diff is enclose in a diff case.

As for super cars, I wont use the term super car but rather competitional cars. The NTC3 is up to the task to be a competitional cars. It won many races just like the serpents and mugens. I am saying this not to side with Associated. In my collection of RC cars, I own a few mugens such as the MRX3 and also an Associated NTC3. The NTC3 is just as good as the other cars out there for its class.

[bigG]

hey does anyone know where i can get these replacement for my msx3 front drive cup to the differential and dogbone.
