Mugen MBX5 Buggy Forum v1.0

[speedydave]

I use the Ofna blue 1/8 box with the single, high-torque motor. Turns my engine over with ease, even when it's cold.

[jmm]

I use a heavy duty (12v) Ofna starter box...works pretty well..

Many of you cite bumpsteer due to the Ackerman.. How can you notice bumpsteer on the track? What are the symptoms?

[masshybrid]

Push down the front end of the car and watch your front end go from 0 degrees toe out to about 10-15 degrees toe out when the chassis bottoms out. I never noticed it on the track, but it certainly doesn't hurt to fix the problem. I made a new ackerman plate, that is .25 thick, but also alleviates the bump steer problem. Due to the beautiful weather here in New England, I have yet to test it out.

[needinpower]

I also use the blue ofna box. It takes some time aligning the car correctly so the starter wheel doesn't touch the chassis but the benefits outweigh this drawback.

[Lil-Boy]

Just finished the kit today. I I have left the bumpsteer in for now until I try it out on the track. It has some of my tires from the mbx4xr on right now saving the new tires for my first race. diff setup is 5000 front 7000 center and 1000 rear with no o-rings. I have the O.S .21 VZ-B with the 2050 pipe so I hope it will be a good combo for the track in my area. Here is a pic of the car. Still need to paint the body though.

[royfan33]

Mudvayne, if you don't want to spend $25 or so for a aftermarket ackerman link. Just stack 2.5mm of washers between the link and the bellcranks. It will take out the bump steer. Some of the aftermarkets links have the 2.5 built in, others(Mugen Option parts) don't. I like the color of the Mugen stuff so thats what I'm running, and I have the washers under there.

[masshybrid]

I posted in the "wanted" forum, but no replies. So here goes: does anyone have a spare body and wing?

[Toiffel]

Hey guys I wanted to know what after market air filters were being used?? I just ruined a brand spanking new WS7II, my x5 had a THS two stage filter installed, I guess because it was such a tight fit, when I put the body on, somehow it squished the air filter creating a gap, it sucked sooo much dirt, at the least I'll have to replace piston and sleeve.
So I installed a S7, with the Mugen air filter.

[royfan33]

I'm running the RB filter set. I put the elbow from the Mugen filter on it though. It's alittle shorter on the filter side. I going to check it out w/the Rb neck. I like it because its a fairly rigid rubber that doesn't flex and kink like some necks.

[cpittmx]

looking for a 2 speed set-up for my X5. Any suggestions?

[MBX4RR]

never seen a 2 speed mbx5 before, dont know if there is such a thing :confused:

[speedydave]

Don't think anyone makes a 2-speed for the MBX5. Why do you want a 2-speed, anyway? This thing is already plenty fast. :)

I don't know about aftermarket filters...I just use the Mugen filter. The OS filter looks pretty nice, though, as does the RB. But, the Mugen is cheap, and it works, so I'm not going to mess with it.

[cpittmx]

Just went to a new track on Saturday and they have some wicked long straights. I went up to a 16t on the clutch bell and was still topped out at less than 1/2 way down the straight. I know someone that has an XR works with a 2 speed just not sure what it is. I also know ofna makes a 2 speed for their hyper 7 but not sure if it would work on the X5 or not.

[MBX4RR]

perhaps your friend made a few modification. As for the hyper 7 searched alittle and didnt find anything for a Hyper. Actually i've never heard of a 2-speed buggy in my life befor this.

I like the O.S. air filters they do the job for me. :)

[OldskoolGT]

I went up to a 16t on the clutch bell and was still topped out at less than 1/2 way down the straight. .

Good grief??!! How long is that straight, 600 feet? :)


OFNA did recently start making a 2-speed transmission for their Hyper 7. I think there is also a 2 speed for the Kyosho Landmax, which is based on the 7.5 buggy.


Toiffel,

Sorry to hear about your engine. I like to use the Mugen airfilters with a homemade pre-filter stuck over it.

[Toiffel]

Thanks Olds.....
I checked and the Mugen elbow is shorter on the filter side, there's about a 3/4" difference, I should have used the Mugen elbow.....
I was trying to get the air filter foams, but I cant find the mugen ones, where can I get them, they didn't come uo when I did a search on ACE Hobbies wuth the part number.

[MBX4RR]

here is just the foam http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXNL66&P=7

here is the whole set of elbow and all http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXNL65&P=7

Hey oldshool... I remember you saying of some aluminum (i think) lower shock shaft plastic pieces that hold up better then the stock ones. Can you point me in the right direction to buy them??? I have the X5 shocks on my Mutant Maxx and those pieces keep stretching. :rolleyes:

thx

[OldskoolGT]

I can get them locally, so I am not sure which stores sell them. Those alloy shock ends are made by Racer's Edge, so you might try a place like Ace Hobbbies.

Or maybe try to make some droop limiting straps for your truck. :)

[s14det]

I was wondering if using the XR rear swaybar would allow for sharper cornering. I race on a 1/10 track the has a few sharp turn and was wondering if it would allow me to go around then in a shorter turn. I ran 35wt in front and 30wt in back...then 5000frt, 7000ctr, 1000bck. I ran the track with the factory rear swaybar and seems like it did not turn has sharp has my XR used to.

[royfan33]

Try black bars frt/rear, and 1-2deg toe out. Works for me.

You can also go with less castor.

[s14det]

I was able to make it better with less castor. What are the Black bars you speak of? What car are they from? has anybody tried to make their own sway bars? i am going to the track this sat so i will be abel to try some thing out. also when I was driving last time it was dry has a mofo. When racing it will be watered down so I am sure that will help with turning.

[royfan33]

The black bars are from the XR. They are listed on your X5 parts list. C1067a 2.1mm front, and C0183 2.6mm rear. Seems like the stock set up may be alittle more suited for European style wide open tracks w/wide sweepers ect.

[rc10gtisthebest]

What shock weights you guys recommend for my X5? I run on a long straight away track with moderatley tight corners..

Thanks!

[thndrchckn93]

What do you guys think of the Hyper 8 Port Race engine? I just ordered one from my LHS to put in my X5. I hope its good.

[MBX4RR]

spec wise it looks pretty good

[royfan33]

I had a 8 port race I ran in a Hyper7. Its a great engine for the $. It lacked alittle bottom so I ran w/1.1 springs and mugen black shoes drilled. Has a good top end.

[MBX4RR]

im thinking about selling my O.S. Max RZ (http://www.msnusers.com/gascars/shoebox.msnw?action=ShowPhoto&PhotoID=13), i was hoping you guys could tell about how much i could get for it before i put it up for sale. Thanks for any help. oh and it hasnt been used.

[cpittmx]

Had my engine screaming wide open on track the other day cuz i crashed hard and it turned the switch off. luckily a marshal shut it down before it grenaded. to eliminate the switch i'm assuming you can just plug the battery into the receiver. Does this cause any problems I should be aware of?

instead of doing that you could keep the switch and do what i did, with a small piece of lexan. Just turn it and the switch cant be pushed back. Got it from RCCA :) : http://www.msnusers.com/gascars/shoebox.msnw?action=ShowPhoto&PhotoID=15

[rc10gtisthebest]

You'll probably wear out the connections if you unplug and plug in the wires all the time. And you'll have to open up the case alot..

-Todd

Can't wait! my x5 gets here Wed. (but season starts Fri Night... Gunna be tight)

[thndrchckn93]

What starter box should I get to start a Hyper 8 Port race engine?

[cpittmx]

hmmm...not a bad idea I might do that. thanks for the idea.

[royfan33]

thndrchcken, one thing I can tell you about the Hyper 8 is that it was the initially the tightest engine I've ever broken in. Make sure to preheat it as much as possible before starting. I just use a hair dryer, and can get it upto around 170 or so.

There are a bunch of good starter boxes out there. I prefer one motor direct drive boxes. I've had some that had two motor, belt drive ect. that are ok, but just more to go wrong on them. It also depends if you are going to use it to start more than one ride with it(ie. offroad buggy and touring sedan.) Some are convertable to start either.

[s14det]

Found a good setup for small tracks with very tight corners. Use XR rear swaybar, no front swaybar. 35wt in front, 30 in rear, full ackerman setting, 5000 frt, 7000ctr, 1000r then go here http://www.twf8.ws/new/tech/car/mugen/mbx5/mbx5build/mbx5-performance.html

and do the shaving of the front of the pillow balls....the car freaking turns like a mofo. I race on a 1/10 track and it takes the sharp turns with ease. Raced yesterday (Sat) with the new settings and was running circles around the other 1/8 scale's(hyper 7's, 9.5 violater, cheap ofnas (they do not count), another X5 with stock setup. If you need some more steering I would give this a try!!!

The track has small to medium jumps, smooth surface, watered...

[muswagon]

Can someone tell me what parts, if any, off the X5 will fit an X4RR?

[s14det]

Shock, diffs, wheels/tires, wing, wheel hubs..pretty much all the small stuff should fit..

[Toiffel]

I'm running a S7II with white clutch shoes and 1.1 springs.
I'm almost 100 % positive that I had some clutch issues this past weekend racing.
The motor was running great, not too hot, but towards the end of the day, I noticed that a couple of times when I started it, and left off the gas it would die, and the same thing happened a couple of times on the track. During the main, I came in to refuel, and I noticed that the engine was struggling to gain RPM, especially from a stand still or coming out of a tight corner, I checked the temp after 10 minute main and it was 240, just in case did the spit test and evaportaed after 5 sec. aprox.
Took the engine out of the buggy, because I noticed that when I tried to spin the clutch bell it would spin the flywheel, inspected it and noticed that the white shoes were almost black, but not deformed or anything, springs were in place, put it back together and tried to spin the clutch bell with my finger, and it moved freely.
The clutch shoes have seen aprox. 14 tanks, what's the cleaning process?? how often do I replace them?? did I overlook something??
Any tips and help much appreciated.
Sorry for the long post.........

Im still on the stock clutch shoes and springs with also a WS7II and man it still runs like a bat out of hell.... I have approx. 3 gallons on this set up. BARELY last weeknd my car stalled.... and the same thing, my clutch bell turned my flywheel. I took it apart and the edges of all three shoes had a small lip that hung them up. I just took them off and shaved off the lips on the shoes, and shes running like a champ again.

I dont know if this is normal but im getting a LOT of life out of my clutch shoes...

I clean my shoes and clutch bell with denatured alcohol....

[masshybrid]

I'd guess it all depends on the track your running on. If your running on a big track with sweeping turns, and are constantly on the gas, your clutch is engaged most of the time. If you run on a tight track with lots of turns and are constantly slowing down disengaging/engaging the clutch , your shoes will see more wear as well as heat buildup.

[windellmc]

I don't use switches anymore because the sometimes fail intermittantly. What I have done is run the battery plug outside the receiver box next to the throttle servo. I then bought a short aileron extension and plugged it into the receiver. I ran that wire out by the throttle servo. Now I just connect the battery to the aileron extension and I've got power. You might want to zip tie or somehow attach the wires to something so they don't move around.

[karl kobernus]

I am not getting much "life" out of my clutch shoes at all either. I am using the mugen alum. shoes and they only last me about 3 race weekends. I am going to try the fioroni slide clutch set up and see if that makes any difference in durability.

i too was thinking about switching too fioroni, i only here good things about the clutch, i read it last longer

[cpittmx]

I've seen the fioroni sliding clutch in magazines but have not been able to find it for sale anywhere. when i go to the fioroni website, actually gs i think, i do not see the sliding clutch there anywhere. I see that horizon is going to be selling a sliding clutch under the sport werks name or something like that. It says made in italy on it so I'm wondering if it is the same as the fioroni unit.

[MBX4RR]

www.fioroni.com has all there parts but shipping is mad crazy expensive like $27 for standard shipping(comes from Europe) :rolleyes:

[karl kobernus]

I ordered the Fioroni slide clutch set up from www.rc-nation.com . For both kinds of shoes,carbon and the teflon, and the flywheel and shipping was about $85. I don't think that the price for that was too bad at all. Considering that I was going through a set of alum. shoes every 3 race weekends @ $20 per set.

Okay now for the next issue with the buggy.

I am turning much better to the right than the left at speed. When testing the slow speed turn, the turn radius is the same to the left and right. I also made sure that my front track width is centered to the chassis, replaced the bearings, replaced pillow balls and the hub carriers.

Basically, how can I get rid of a mid to high speed push? And I know I could slow down, but to me that's not good for winning.

[Toiffel]

After a succesfull weekend of racing 1st place, I was doing the scheduled maintenance when I noticed that I had no front diff action, took it apart and 1st suprise, the lower front brace broken, opened the diff case and no fluid at all, put the diff back together, and still, boh wheels turning at the same time, what has happened is that the cup joint is seized, can't get it out of the conical gear......
Any thoughts what to do??? I tried giving it some light hits with the hammer, but nothing, tried WD40, same thing.....

[penggoy]

I need an aftermarket lower front brace to replace the stock part (E0112). Should I buy mugen (E0119) or do you guys have other manufacturer in mind and how much is it? thnx in advance

[MBX4RR]

you should check out and see if Fioroni makes one.

[OldskoolGT]

I've seen several of the E0119 parts break. I suggest just keeping an extra stock part on hand.

[Mudvayne]

I decided that I am going to upgrade to a better steering ackerman for my mbx5. I've heard of the one from Ratza's and also the one from Racer's edge. Which one should I get? Is one better than the other? Thanks in advance.

[OldskoolGT]

Both parts have a similar design, so the choice is up to you.

[rc10gtisthebest]

Finally finished my x5. Need an engine now. while building my kit i noticed the Right Front upper arm has a stress crack on it. I was wonder if any of you have seen anything like that before from the factory? I was thinking of the Fantom .21 for the X5 anyone have any experience with it?

Thanks

[HIRISK]

Hi Guys,

I am new to this forum, so G'Day from Australia.

I have just purchased my first Mugen MBX5. I bought it from a guy who races in Texas over their in the States and had it shipped over here to me. I had a call from Customs today and it is there waiting to be picked up!! Yay!!

It has some nice mods.....
ported WS7 II
Racers Edge Front and Rear Shock Towers
Racers Edge Front and Rear Chassis Braces
Racers Edge Centre Diff Plate
Racers Edge Ackerman Plate
Fioroni Hinge Pins
Fioroni Chassis
TRC Atomix Tires
Kyosho 10 Spoke Wheels

As soon as I get it home I will take some pictures and post them here.

I am sure I will be back here for advice and set up tips sooner rather than later.

Cheers,
Shaun.

[savagepicco26]

okay, so i've been thinking of getting an MBX5 for a month or so now. i currently race my Savage in the monster truck class and turn lap times a couple seconds slower than 1/8th scale buggies on a 36sec ave (for the buggies) lap time track (it's a huge track). i have a contact that can get me a new MBX5 kit, P5 motor, and the Mugen starter box (PRO STARTER BII) all for about $760. i have heard mostly good things about the MBX5 and i'm pretty sure that i want one. the most common problem is with the diffs leaking fluid out. has anyone figured out why they do it? i have a savage and run 7000/3000 wt oil in that and my diffs have never leaked. i'm just wondering what's different about the construction that allows the MBX5's to leak. are there any other common problems with these cars? what about any needed immediate upgrades? this car is going to be strickly for the track. i've got my savage for bashing. any help would be appreciated.

[rc10gtisthebest]

the diff problem is because the o-rings that seal it are a tick on the thin side. If you can find some thicker ones and replace them they will not leak. I have only driven my X5 10 times (HARD!) and I bent the Ackerman link. I would suggest replacing that.

-todd

[cpittmx]

people are selling the o-rings on ebay. I haven't bought them or used them so i cant say for sure if they are a fix or not.

[jmm]

I'm selling sets of the aftermarket o-rings on Ebay, as well as directly.. Rebuilt my diffs with them, and diffs are much more consistent.. Selling in sets of 8 (enough to rebuild car, plus 2 spares).

[savagepicco26]

links? price?

How many people here plan on going to the r/c pro series 2nd round in Charlotte, NC @ Lance's track?? I'll be there. Hopefully I'll do better than 64th place this time.

[penggoy]

I just finished rebuilding the front universal and I noticed the front and back lower arms have some play is this normal and wont affect the handling etc. of the car. Or should I put caster clips on them? The manual doesnt say anything about it.
I put associated green slime on the cup joints and also inside the diff where the o rings are placed. I hope this will fix the leaking if not ill buy the o rings on ebay.

my Hitec 645MG just died yesterday, my car just stopped steering. Took it apart and none of the gears(metal) are bad, power gets to it because I can here a buzz when I try to turn it. I guess it just died :(
Anyway what servo should I get,i really would like to get the Airtronics 94358Z but it cost $104 :mad:

if the Hitec is less than 2 years old, and you have the receipt, send it back to Hitec. They'll fix it. i had one in my Savage that i didn't readjust my end points on my radio and it stripped out the metal gears. Hitec fixed it, no questions asked. go to http://www.hitecrcd.com/ and then Support, and then "Service and Repair" kind of a pain, but it's better than buying a new servo. took about 1.5 weeks from the time i sent it out.

[rc10gtisthebest]

actually a 1.5 week turn around is actually very good. I've heard places like Traxxas, Ofna etc have a really slow turn-around, about a month or so..

The main reason I'm sticking with Hitec is for that Warranty.. I've had my 5945 replaced 3 times.. No questions asked.

[rc10gtisthebest]

Anyways, Right now I have my CMB LSI from my RR in my X5 and this thing flies! I really need a different engine for it so that my GF can use the RR w/cmb as her buggy setup. I was wondering about venturing into a WS7II. Can anyone show me the cheapest place to pick one up? Also what pipe would you guys recommend?

Thanks!

yeah, Hitec sent this card saying they had received the servo and had listed a work order for me and that i should expect to hear something within 2 weeks. 2 days later, the servo showed up! Ofna had to fix my Picco 26 for a backplate recall and it took about a full month for turnaround.

[thndrchckn93]

Im gonna start to race my X5 this summer, first race is May 16th. Just a local track. Some of the other guys there have X5's. One is running with a Top SBK01, the other has a REX P5. I have a Hyper 8port race. There is also another Hyper 7 with the P5. This will be my first year of racing. What should I do to get my buggy prepared for racing? It's totally stock, just got done building it about 3 weeks ago and Im still not done breaking in the engine. I have heard about problems with the diffs leaking, is it all of them that leak or mainly just one? What should I do to fix it, silicone seal around it? Are there any other problems I should know about before I race? Thanks

The o-rings on the outdrives leak rather easily. You can replace them with thicker ones. As for upgrades: front lower hinge pin brace, ackerman plate, and a rear chassis brace. That should be it. My buggy has been to hell and back a dozen times and these are the only things I've had problems with( my fault of course).
I've been running mine quite a bit ( 2 gallons so far this year), actually it's all I'm driving right now, and it gets better each time.

[Toiffel]

OK my Speed II clutch is coming in tomorrow, any tips or recomendations??
My current clutch set up is :
white mugen shoes, 1.1 springs with a S7II, going to change it with the new clutch, so any help or tips much appreciated!!!!

ordered another Hitec 645mg today because my old one stopped working a few days ago. I put the old one back together today and it worked just fine :rolleyes: I have no clue what happened, but now i think im going to put the new one in my xxx-nt :D

I have had very bad luck with the 645mg servo. hitec is always good about repairing them but that doesn't help much while at the track.

[winning edge designs]

Well, even with a bad servo your car will look great with a JConcepts MBX5 Illuzion body on it!!! Have you checked them out yet?......Jim

[MBX4RR]

you wouldnt happen to be the guy Jim who is the designer/painter of the illuzion bodies would you :rolleyes:

[rc10gtisthebest]

MBX4, Hmm looks that way to mee to.. LOL both from same area and everything.. LOL

The Illuzion bodies do look better then sotck though...

[Toiffel]

New body, what do u guys think???

[MBX4RR]

looks good :) but is it an Illuzion body? ;)

[thndrchckn93]

Well, unfortunatly today I didn't get to practice at the track with my new X5 today due to poor weather. Our racing season starts next Sunday and Ive only practiced on the track once with my GT, because I didn't have the X5 broke in yet. I only have 14 tanks~1/2 gallon on the engine, the engine is a Hyper 8port race. I hope to get another 15-20 tanks on it by next weeks race. Any thing I need to change on this buggy for racing? It is totally stock, I have heard of the diffs leaking, which diffs leak, all of them? I haven't noticed any of them leaking yet using the stock setup. Where do they leak at, maybe I overlooked something? The track will probably have only 9-10 1/8 off-road racers, but most of them have nice buggies and engines, MBX5 w/ P5, MBX5 w/ SBK01, Hyper 7 w/ P5 those are the main ones I saw at last weekends practice, looked pretty fast. So I have some GREAT competition, at least for me, to deal with. This will be my first race ever so I will mainly concentrate on finishing. I just want to set my buggy up so it will last. Any other suggestions? Thanks

[jmm]

Diffs leaking on the MBX5 is a chronic problem.. Causes inconsistent diff action and reduced stopping power when the oil gets on the brake pads/rotors, not to mention having to rebuild them often.

Carolina R/C offers an aftermarket set of Diff O-rings for the MBX-5. They are available on Ebay, or for more information, email CarolinaRC@adelphia.net

[JamminJay]

does anyone know where the cheapest place to purchase an X5 is? Thanks in advance.

[rc10gtisthebest]

Ebay. I've seen them for as low as $508. That's where I bought mine new.

[winning edge designs]

MBX4RR, ya, that's is me.....But I only said it because I meant it. I am honestly really proud of the work Jason and I did on the Illuzion series. They met our expectations and there's more to come!....hope you racers dig em'!....Jim

[OldskoolGT]

Ultimate Hobbies sells X5s for $499 and has free ground shipping.

[karl kobernus]

Hey Jim can you give us a look at one of the Illuzion bodies? If I like it, where could I get one?

[MBX4RR]

them have them on ebay>> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=49214&item=3191707020&rd=1&ssPageName=WDVW

[Toiffel]

New body, what do u guys think???
It's a Proline Crowd Pleazer Body, and the paint job was done by my buddy "The Wicked Clown" Dave

[RCRACER2471]

Hey guys. I was looking to get a Mugen MBX5. The only problem is where to find parts. What places online support Mugen parts and carry a full line of them so if something were to brake I could get it all from one place.....

[Toiffel]

I always get my parts from acehobbies.com and now started with ashfordhobbies.com :)

[Toiffel]

With custom decals....

[rc10gtisthebest]

Toiffel, if those decals were real and not superimposed they'd be pretty sweet. ;) :p

[Toiffel]

lol, they will be real tomorrow when I print them, just finished playing with them........
couldn't resist.....

[thndrchckn93]

Is there any quick fix for the leaky diffs besides buying new thicker o-rings?

[penggoy]

lol, they will be real tomorrow when I print them, just finished playing with them........
couldn't resist.....
where do you race your buggy? westchester NY right?

[Toiffel]

Regularly at Barnstormers in Chester, NY, and sometimes like this weekend coming up at Wolcott, CT, don't forget the East Coast Nitro Challenge at RC Madness Enfield, CT on the 22 and 23rd of may.......
How about u?

[rc10gtisthebest]

Is there any quick fix for the leaky diffs besides buying new thicker o-rings?


Unfortanutly not. But the orings are no more then $5... YOu could grease the hell out of the original ones but that might not work...

-Todd

[thndrchckn93]

Well, I guess I will have to race this weekend with leaky inconsistent diffs and fading brakes, shouldn't be to hard.

[thndrchckn93]

When I take apart the diffs I will probably put in new oils, what weights do you guys recommend for a good setup?

[jmm]

5k, 7k, 2k works well for me.

[savagepicco26]

7-7-3 is what most guys at the big track here run

[evanb]

I am thinking bout getting back into 1/8 Buggy. Which Futaba or Jr servos would be good for steering and throttle, Also which Novarossi Engine/ Pipe combo works well for racing.

[OldskoolGT]

Futaba 9451 digital servos work very nicely in buggies.

9886 pipes or the OS T-2050 pipe works very nicely with with most of the Novarossi/RB engines I have seen.

[MBX4RR]

Regularly at Barnstormers in Chester, NY, and sometimes like this weekend coming up at Wolcott, CT, don't forget the East Coast Nitro Challenge at RC Madness Enfield, CT on the 22 and 23rd of may.......
How about u?

I live about 25 min. from Barnstormers :)

[evanb]

So what would be better a Novi P5 or a RB WS72

[rc10gtisthebest]

I've heard the P5 is more of a Top Speed engine and the WS7II is a balls motor. (Low End). But these are jsut what i've heard..

-Todd

[thndrchckn93]

There are a couple P5's at my track and they seem to have lots of low end, but I havn't seen the WS7II's run so I dont know about them.

[evanb]

I was also trying to find some good digital servos....I like futaba, I will be getting eithr a Futaba digital radio or a JR..I was looking @ the 9451 servos...what is a good buggy servo metal gears for a buggy

[adim_x]

I have a ws7 II motor , it is more a mid to top end, while the p5 is a low to mid range engine, the more ports you have generally the more time it will take a motor to spool up and make power i believe. i am looking for more bottom end, so i am going to be buying a p5. i could make my ws7 have more lowend by putting larger clutch springs on, but i think that causes more clutch wear and tear. if you race on a tighter track i would recommend a p5, or a new rb s5, they are both awesome, and the rb is a little cheaper like 230 at ace hardware hobbies

[rc10gtisthebest]

Does anyone have any extra window-masks and or know where I can get some?

Or does the kit even come with some? Because I'm tired of running my X5 without a body.. LOL..

Thanks,
Todd

[winning edge designs]

Todd, I would avoid running without any body, even if you run a clear or one color spray bomb job to protect the components. Of course you could check out the Illuzion bodies at J Concepts dot net, since they come with window masks and cost about $10 less then the stock body.......We haven't even talked style yet? LOL, shameless plugs again!.....:), Jim

[rc10gtisthebest]

Jim, How many advertisements is that for The Illuzion body? LOL...

Anyways, I know I shouldn't be running without a body but I haven't even given the new engine full throttle yet. Hell not even 75%.. I baby my stuff.. HAHA..

Anyways I plan on picking up an Illuzion body after a new radio.

But I am going to be painting my body and I need to know if the kit came with window masks or not? Because if it Did I have misplaced mine and need to find them. But if it didn't I don't want to tear up my house looking for something I never had. ;)

Thanks,
Todd

[MBX4RR]

^^Jim looks like all the advertising finally paid off :p

[rc10gtisthebest]

lol..

Does anyone have an answer for my question though???????????????????

[winning edge designs]

RC10, the Mugen that I biult didn't have any window mask either, so you'll need some masking tape and a good exacto blade....plus a steady hand, to trim out your own on the body.......Jim

[rc10gtisthebest]

damn... that's what I was afraid of. But It really doesn't bother me.. Thanks for the answer though.

-Todd

[savagepicco26]

you could use liquid mask. i think that's easier to use than tape.

[evanb]

Where is the best place to buy a P5 online? Doe sit matter if I get a Rex, Top, or Novarossi P5?

[PaulH]

Where is the best place to buy a P5 online? Doe sit matter if I get a Rex, Top, or Novarossi P5?

Novarossi, Rex, and Top are different product lines from the same company. As far as I know, there are no significant differences between the three names.

Try http://www.nitrohouse.com/. I saw the Rex P5 for $320 and the Top P5 for $280.

[cpittmx]

Novarossi, Rex, and Top are different product lines from the same company. As far as I know, there are no significant differences between the three names.

Try http://www.nitrohouse.com/. I saw the Rex P5 for $320 and the Top P5 for $280.

From what I have read Novarossi makes them all, and the better stuff wears their own logo and the rest gets sent out to Rex, and top. I think Novarossi also makes the RB concepts stuff to RB's specs. Have I misunderstood what I have read?

[cpittmx]

I've heard the P5 is more of a Top Speed engine and the WS7II is a balls motor. (Low End). But these are jsut what i've heard..

-Todd

interesting I have heard exactly the opposite and that the WS7II turns on and off like a light switch, doesnt turn on until its on the top end, and is no good for smaller tracks. I'm running the O.S. VZB and think its a good low to mid motor.

I see adim confirmed what I had heard, guess I should have read on before posting...sry.

[Toiffel]

OK this clutch is driving me insane, I had the stock mugen clutch system installed, and 3 times the clutch nut came loose, and pushed everything forward.... then I switched to Speed II clutch, and same thing has happened twice. I haven't used threadlock b/c with my XR never had too.
What could the problem be?? Should I use threadlock??? What about the collet that comes with the kit, is it any different from the one that comes with the engine???
Thanks for your help!!!

[thndrchckn93]

I use threadlock and havn't had a problem yet. The collet that comes with the kit should be the same, but I used the one that came with the engine.

[PaulH]

From what I have read Novarossi makes them all, and the better stuff wears their own logo and the rest gets sent out to Rex, and top. I think Novarossi also makes the RB concepts stuff to RB's specs. Have I misunderstood what I have read?

Novarossi makes engines for several different manufacturers, RB, NovaMEGA, and the newer JP Racing engines included. This is very similar to the semiconductor industry, where IBM actually makes AMD chips, and Texas Instruments has made processors for Sun Microsystems for the past 10+ years. Setting up a new fabrication plant for anything is an expensive proposition. Using existing facilities is far preferable, especially in the small quantities that most of the "specialty" companies (RB, etc.) sell their engines in as compared to Novarossi.

I think the three different product lines from Novarossi are really identical. They're not casting three different engine casings and three different heads and so forth. They cast everything once, then hand-pick the best fitting parts for the Novarossi. The remaining parts go into the Rex and the Top engines. This means the tolerances in the Novarossi-branded engines might be a little better, making it last longer and provided a little more performance, but the for average basher, the Rex or Top engines will be just as good for less money.

[griff]

[QUOTE=rc10gtisthebest]I've heard the P5 is more of a Top Speed engine and the WS7II is a balls motor. (Low End). But these are jsut what i've heard..

p5 has more low end than a ws72 and a ws72 has more top than a p5.
i have both engines and have run side by side.
so small tight tracks p5 .
the ws72 dose have a smother power band due too the low end making it easyer to drive

How do the compare reliability wise and idle wise?

[winning edge designs]

NovaRossi manufactures them, but to each companies requirements. I heard a rumor that Novarossi bought RB, not sure though. Rex and Top usually tweak mass produced engines further, to suit thier own needs, as RB does with it's higher end engines............Jim

[rc10gtisthebest]

Alright I guess i'm wrong...

[evanb]

Does anyone know which JR racing digital servo is best for the mbx r?

[MBX4RR]

best possible JR is probably >>>http://horizon.hobbyshopnow.com/products/description.asp?prod=JRPSZ8550

[evanb]

is it better to run aluminum or plastic servo horns?

[MBX4RR]

You may want to get aluminum for the steering because there is always the chance of the servo horn slipping or just bending due to a crash, even though it is unlilely because of the servo saver, but still possibly. But the you need to get the aluminum for the throttle to match the steering :cool:

Really though I dont think its that important it mostly for looks and only alittle for performance.

[griff]

How do the compare reliability wise and idle wise?
reliability the as good as each other the ws72 dose idle better but this is also down to tunning.
just ordered a novarossi 421b will race it next weekend.
here in the uk this is the new king on the block average 2 mins long on a tank of fuel faster than a ws72 top end more like a c5 and a smoother power band right through the range.
will let you all know the out come

[rc10gtisthebest]

If you get plastic, make sure you get a good quality plastic. I have had many servo horn teeth strip out on me in my X4RR. That's why I only use Aluminum in my X5. Also, if it strips it may take off at WOT if it is the throttle, which has stripped on my serveral times.

-Todd

[OldskoolGT]

I've had good luck with the plastic servo horns that come with Hitec servos. I have run them in 4 buggies without any problems. The drawback of aluminum servo horns is that they will often develp slop in them, unlike plastic.

[uDi_MP75]

I run S9451's in my buggy too and they seem really nice. Comparing to my friends new KO 2344 with a lot more claimed torque, my Futaba seems to match it in torque and blow it away in speed. I can only imagine that the S9350 would be even better.

And for plastic servo arms, i've never had a problem with them.

Ive ordered some blue aluminium ones, just for looks though. They use plastic inserts in them though, so it's not metal on metal on the servo shaft either.

No idea why i'm asking here, but does anyone know how the T-2050 pipe compares to the 063's performance wise? I've got an RB 63 and love how it performs, but it dents easy and I need a new pipe soon, just wondering if the 2050 will match it in performance. Don't really care for the 086 so dont compare to that..

[rc10gtisthebest]

just get the hardcoated Rex 053 I think it is or 054 something like that. It's basically the same a the RB 063 just Rex and Hardcoated.

-Todd

[evanb]

Whats a good receiver hump pack for the Mugen? I am going with digital servos so want a good pack...

[royfan33]

Novarossi/Rex/Top are all in the same. Rex and Top do not "tweak" Nova motors made for them. They are all the same company. Rb and Jp are separate companies w/motors made for them by Novarossi. Same for Medial, the NovaMega line for Serpent and a few others.

Jim Hottinger of Fusion Motor Sports formerly of Paris Racing is the sole importer for the Top line. He himself has worked on hundreds if not thousands of Nova engines says the internals are all identical. Ie. The internals from a Top/Rex/Nova P5 are the same exact thing.

The reason for the Nova/Top/Rex lines has to do with importing and exporting rules, and the fact that one company can claim to be the "sole importer" Rex.
While another has the Top line. Last year Mugen was importing the Rex line, Trinity had the Nova. Mugen is now importing the JP line, and Fusion the Top. No sole importers of the Novarossi name as of now.

[OldskoolGT]

Udi,

The OS T-2050 is comparable to a 9886 pipe. Smooth power on the bottom and an incredible top end when combined with the right engine. The pipe is completely worth the price IMHO because it is incredibly durable and will easily outlast any RB, Novarossi, or OFNA pipe.

rc10gtisthebest,

EFRA sanctioned pipes are numbered in a consistent way among different manufacturers. A Rex 053 pipe will be the same as a RB 053 pipe.

[speedydave]

Hey Jim can you give us a look at one of the Illuzion bodies? If I like it, where could I get one?

I know I'm a bit late, but I haven't been checking the board for a while, so...

I've got a Mugen Illuzion body for my MBX5. I still haven't trimmed it or put decals on it or anything (my MBX5 is in the middle of a rebuild right now), but the guy who painted the body for me took these pics (he hadn't gotten all of the sharpie off of the body yet, so not all of the lines look as crisp as they should). I've got the body in my hands now, though, so once I get my MBX5 rebuilt, get the sharpie off the body, and trim and decal the body, I'll get some mounted pics of it before I dirty it up. :cool: I got my body by ordering direct from JConcepts (http://www.jconcepts.net).

[speedydave]

Yeah...

[evanb]

Are most of you guys running slide or barrel carbs? I just got a P5 and it came with a slide...I used to run barrel...should I return it for a barreL?

[speedydave]

I've never heard of a big block coming with a rotary carb. The buggy's set up to run a slide carb, too (as is every other buggy on the market). What did you used to run rotary (barrel) carbs on?

[savagepicco26]

yeah, i've only seen slide carbs on 21's and up. slide on the S-25 and the Picco .26 that I had for my Savage.

[MBX4RR]

They have .12 & .15 slides too :rolleyes:

[savagepicco26]

They have .12 & .15 slides too :rolleyes:
yeah, but i doubt one of those would move an MBX5 very well. :p

[speedydave]

They have .12 & .15 slides too :rolleyes:

How I interpreted what he said was that he's never seen a rotary carb on a .21+, only slide carbs.

[MBX4RR]

yeah, i've only seen slide carbs on 21's and up. slide on the S-25 and the Picco .26 that I had for my Savage.

yes i now under stand how you can see it in two ways-
1st is- that on .21's hes only seen slides
2nd is- that hes only seen a slidies on .21's and up

[rc10gtisthebest]

No your all wrong they have Rotary .21's !!!! You just have to modify the carb off of a Airplane or Boat. LOL ;) :p

thanks, was hoping you might have some idea how it compares to the 063 though. I did have an RB 086 once, but in two piece setup, and with a cheap brand manifold, so I don't think it ever performed like it was supposed to. So consequently I don't really know how an 086 performs. I've got a one piece rb063 now and I really like how it performs, except it dents when you look at it too hard.

And the durability factor is why I wanted the 2050 in the first place, but i dont wanna buy it until someone compares it to an 063 for me so I don't get it and end up dissapointed :(

both my motors are 7+2+3 ports and quite topened oriented so i need something that'll liven up the bottom, clutch aside.

[evanb]

Where can I buy the 2050 online?

[uDi_MP75]

The cheapest i've seen is from rc-mushroom in hong kong, should still be cheaper than anywhere else after postage costs even.

http://rc-mushroom.com/product_info.php?products_id=372

and obviously tower hobbies if you want that...

http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXBPK8&P=ML

[OldskoolGT]

Udi,

I've never had a 063 pipe so I can't offer a comparison. So far, I have got excellent results with the T-2050 combined with the Picco G1 XP, Rex P5, and WS7.

I like the T-2050 so much due to its durability, I think I might just try to run engines that work with it. I have a 1 year old T-2050 with no dents in it. That's in sharp contrast to the 2 week old Jammin JP-1 pipe that is already dented at the bottom.

[speedydave]

Have any of you guys tried the Fioroni sliding turbo clutch on your buggies? If so, how did it hold up, and how did it perform? Is it worth the money? I want a clutch setup that's as snappy as aluminum shoes w/1.1mm springs, but doesn't require the constant maintenance.

[evanb]

How often are you changing your shoes?

[speedydave]

I'm actually still running the stock shoes, but every other raceday I take my clutch apart and de-burr the shoes and make sure a glaze isn't forming on the shoes/CB.

For whoever was asking about the JConcepts Mugen Illuzion body, I finally got mine mounted up. My buggy's kinda dirty, but here it is...(Paint by Troy Shear, aka TSR6)

[HIRISK]

[evanb]

I just got my kit together..I have a coupel questions.

1) Should the clutch bell be tight or can it have a lil back and forth movement?

2) Are there any test I can do to make sure my diffs went together good...you know like hold one wheel type thing?
- When I rotate each wheel the opposite wheel turns the other way...I assume this is correct? when I turn both rear wheels forward the front do not move..not sure if this is correct..I am running stock diff oil 3k/3k/1k

[samcim]

hi all, 1st post , im from the UK and im buying a MBX-5, WS7II (both new from top options) and ive got a 3PK tranny, .063 pipe, futaba S9402 for the steering and a hitec 625 for throttle. oh and ive got a few hopup's already (ackerman plate, front lower support plate, chassie braces, front & rear shock towers (all mugen option parts) white clutch shoes, 1.1 (shiny) mugen clutch springs and a 14T vented clutch bell) ill be racing manly on grass. anyway, what you guys recommend fot the setup i use and any tips at all would be great!!
cheers guys

sam

[savageP3]

would this be a good combo-
MBX-5
OS RG
Jammin Pipe
True Start starter box
JR XS3 hitec 645 mg steering/ JR 85 oz/in throttle

also what diff and shock oils are good for a tighter track with one 4 ft jump?
what extra parts should i have on hand?
what are some first hop ups i should get?
are there any building tips i should know?

[masshybrid]

Evan- a little play in the clutchbell is good. Sounds like your front brakes are set too tight when you spin both rear wheels.

Sim- Running on grass? I've never done it but I would assume it is comparable to running on carpet with onroad cars in which you have ALOT of traction. My guess is that you would set it up low and stiff( use the droop screws in the a-arms and go with heavy shock and diff oils) . Any others running on grass ????????

Savage-Sounds like a good combo with the exception of the steering servo. I would suggest using the Hitec as the throttle and getting the fastest/most powerfull steering servo you can afford.
My car has been through hell and the only parts I have broken are the ackerman plate and front hinge pin brace. The rear chassis brace is another part that could be upgraded later down the road.
As for building: dont use the little o-rings in the diffs, grind flat spots on the pins in the cvd's, and obviously, use loctite on any metal/metal contact. Plan on setting aside an entire day for the assembly.

[samcim]

grind flat spots on the pins in the cvd's, .what part of it? have you got a picc? and whats it do/for?

cheers for the advise too :)

sam

[OldskoolGT]

Grind a flat spot onto the CVA pin where the setscrew touches it. I'd also reccomend that you clean the CVA parts off with brake cleaner before you use Loctite the setscrew in place. And use red (high strength) Loctite.

[savageP3]

does the kit include fuel filters? if not which ones and how many should i get?

[samcim]

ahh i get it now :) cheers, hmm red loctite! really?????

thanks!

[OldskoolGT]

Yes, red Loctite. Even with red Loctite, the setscrew will still come out due to vibration.

The X5 kit does not come with any fuel filters, except for the one inside the tank. Kyosho fuel filters are a good choice.

[rc10gtisthebest]

I use the Mugen Fuel Filter on my X5. Works pretty good.

[MBX4RR]

yeah i like I stick with Kyosho,mugen or ofna for my 1/8 engines but for my losi i have a dynamite..dont ask me why :rolleyes:

[savageP3]

is the OS RG a good engine for a 1/8 newb? ive raced MT's but never 1/8

[rc10gtisthebest]

I have the rg in my madforce seems to have decent power. Its very user friendly.

[jmm]

I got the RG as my first nitro engine (and ran it in my MBX5). Easy to tune, forgiving, and has surprising power.. A great first engine to use until you can handle the power...and then move up! :)

hi all, ive just assembeld my diff's in the gear box on my MBX5, and when i turn the CVD it kinda feals like its grinding a little, is this supposed to happen????

it sounds like the crown gear is rubbing on the plastic casing somewhere inside, will this wear out? or shall i strip them :`(

oh and ive shimmed them too

cheers!

I don't shim them when they're new, that might be causing the gear mesh to be a little on the tight side....

[rc10gtisthebest]

Yes that is probably what is happening. To tight of a mesh. It will eventually wear-in to it's self but it would be a a much smarter Idea to take the shims out. That's what I did.

[samcim]

great advise guys cheers!. ive finished with the kit now :D just need to plonk the WS7II in :D

[MBX4RR]

How many car bodies do you guys have? I myself have 4 for my buggy.

If anyone is interested in buying a Futaba 3PJS i am selling one on ebay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5902703429&sspagename=STRK%3AMESE%3AIT&rd=1

[savageP3]

well i have three for my savage

[Mudvayne]

I've been having a venom fail-safe now for a little while but could not find a small enough battery pack for it to fit in the case. So this is how I'm going to do it now in the picture. It is a snug fit but it does not seem to be too tight. I think it will work but is it a good idea? Thanks.

[jmm]

That is exactly how I mount my failsafe in my MBX-5..

-Jon

[savageP3]

is anyone here looking to sell your MBX-5? im in the market.

[evanb]

Did the chassis of your MBX needed to be opened for the starter box to work ? I am starting to setup my starter box and would like to see some pics of your guys starter boxes

[samcim]

i got the BII pro starter box by mugen and i must say it rocks!!!

turned over my brand new WS7II sweet!

[savagepicco26]

where did you get it and how much. i need a new box. i bought a used one that comes with the Ofna Hyper 7 PCR. it was $30, but it came with 2-3000mAh NiMH batteries, brand new. the batteries alone cost $50. guess it just saved me $20 towards a BII.

[savageP3]

the h7 starter box wont work for anything but an h7. also it sucks. the belt drive slips all the time.

[savagepicco26]

the h7 starter box wont work for anything but an h7. also it sucks. the belt drive slips all the time.
yeah, i found that out. but like i said, i saved $20 on the batteries alone, so that's $20 towards the BII. we've got a local Mugen dealer in Charlotte that sells the BII's for $95. I don't know if that's a good price though. the only other place i've seen them is nitrohouse and they're around $120 there if i remember, plus shipping.

This is the rex/Novarossi .21 Inline Pipe and header for a 1/8 scale Buggy , its polished finish and has only been run about 5 tanks. Mint condition

$90 shipped

[SN VipeR]

I would strongly suggest to put the receiver into some foam. This reduces vibrations and the likeness of radio interference. A balloon or two over it help when driving in rain.

Sorry if this has been asked before, but what is the best and cheapest source for an MBX-5 in the US? Looking to buy one since I saw it at my first race this week-end. The car rules!

[OldskoolGT]

When are people gonna learn that Ultimate Hobbies has the best prices in the USA? Call them on the phone to get the "real" prices.

[savageP3]

is $475 a good price for an MBX-5?

[thndrchckn93]

thats what I payed for mine SavageP3.

[Booyah]

Please do tell where you can buy them for 475? Lowest I found is 499

[thndrchckn93]

I got mine from a guy that just bought the X5 but before he could put it together his friend was selling his brand new K3. So the guy bought the K3 and was selling his X5. All he wanted was $475.

[savageP3]

im getting mine NIB from a guy that i race with.

[rc10bob]

Hi, I have a question and would appreciate any information, are putting my mbx-5 together, I was told to put 5-7-2 in the diff and leave out the 4mm o rings , yes or no, and do you get 2000wt for the rear my hobby shop says they don't make it.

[al56ex]

rc10bob, you can go to www.mugenracing.com and click on the set up sheets in order to find out what set up the sponsored racers are using. As to the 2k diff wt, what most people do is mix 1k with 3k in a 1:1 ratio to creat 2k; your kit should come with both.

[rc10bob]

Thanks for the comeback, and the web sight it looks like it will be helpful

[savageP3]

hows this look for hop ups on my X5 when i get it?
http://acehardwarehobbies.com/2.2/catalog/shopping_cart.php

[rc10gtisthebest]

I ordered a full set of Eck-Tec option parts...

[savageP3]

i want mostly fioroni tho cause i like the blue. some things i will get mugen but do i need anything else to fix the weak points?

[rc10gtisthebest]

Umm, the ackerman link, Chassis Braces are the musts. Everything else just helps.

[jmm]

Gents, just got the Eck-Tec new black option parts in for the MBX-5... Awesome stuff.. www.mbx5parts.com launching on Friday..

[rc10gtisthebest]

edit: Meant to say that i PLAN on ordering the Eck-Tec Stuff.......

Jon, sent ya some mail back

[savagepicco26]

i finally got everything squared away. i got an unbelievable deal on a BII starter box. got a used starter box including 2 6-cell packs with GP3300 NiMH cells complete with deans connectors. all for $41 including shipping. starter box works great. almost like brand new. already had it at the track 3 times now. getting a custom body painted from Andy at www.andyscustomgraphics.com too. this car is awesome, i love my MBX5!

[KyoshoKev]

cheers

[rc10bob]

Hey guys, I have a question, I'm doing a conversion to my MBX-5 in two a monster truck I do dirt oval racer it's pretty big here that's why I'm converting my MBX-5 hoping for a edge, question as somebody said to put very heavy oli in the centre diff and grees in the rear. for Oval racer appreciate any help on this matter.

rc10, you know that JT racing has a conversion, don't you?

Anyways, I would stick with 1000 in the back.

kyosho kev, it comes along with the side mudguards.

[OldskoolGT]

The pipe guard # is E0403A

Here's a pic.

[KyoshoKev]

much appreciated...

is it really worth getting to protect the rb pipe stinger? :cool:

[rc10gtisthebest]

it will help so the stinger wont bend, chip, or even break off.

[samcim]

yeah it works great! ;)

[karl kobernus]

The plastic piece is definately needed for the RB pipe. I find the RB pipes perform great, but leave a little to be desired in the toughness catagory.

Try the Jammin' pipe. It works well and the stinger is well protected all on it's own, and the plastic piece helps too.

[jmm]

Yeah, that Jammin' pipe is tough! I'm running an RB now, and love it, but will probably try a Jammin next once the RB takes too much abuse..

Hey Guys, When you get the oil in the MBX-5 kit and it says 350wt or 400wt is that the same as 35 weight oil and 40 weight oil Help

[rc10gtisthebest]

Yes it is

[kreidel1]

Hey Guys, When you get the oil in the MBX-5 kit and it says 350wt or 400wt is that the same as 35 weight oil and 40 weight oil Help

Unfortunately not, you figure it would have been easy to keep it all the same but oils differ from manufacturer to manufacturer with only a couple being the same. Mugen oils tend to run slightly heavier than there counter part.

[jmm]

If you keep breaking the front and rear toe blocks, Eck Tec has some awesome aluminum option parts for the MBX-5 that strengthen the area, as well as give you more adjustability options than the stock pieces..

The front piece allows you to adjust the antisquat from from 1° to 3° in .5° increments (1°, 1.5°, 2°, 2.5°, 3°).

http://www.carolinasrc.com/pics/products/Large/c93004.jpg

The rear piece allows you to adjust the rear toe-in from from 1° to 3° in .5° increments (1°, 1.5°, 2°, 2.5°, 3°).

http://www.carolinasrc.com/pics/products/Large/c93003.jpg

Eck Tec options available on www.mbx5parts.com

-Jon

[SN VipeR]

Isn't it called antidive in the front? I thought antisquat was the exact opposite in the rear.
I love those Eck-Tec parts. Might order some once (if?) I get my prospec. Funny thing is they're probably cheaper from across the pond than in my neighbouring country where they're actually made. :)

[dirtbug]

hey guys, i have a quick question. i see that the price of the mbx5 is reduced, because the juiced up version has been released. so, is there another new mugen (mbx6) buggy just over the horizon, or will this platform be up to date for a while? if i get permission to build a track i am definately going to buy a new buggy to replace my hyper 7. that new price for the standard kit is attractive.

[LoSick]

bye bye Kanai, hello Prospec, new world champ!

[jmm]

Probably are...most of my buyers have actually been overseas.. I sell the Eck-Tec stuff under retail..

[OldskoolGT]

The X5 has only been out for around 1 year now. It won the ROAR Nationals and the IFMAR Worlds this year. I am pretty sure it's going to be around for awhile.

[winning edge designs]

It may win the Region 4's next week if I have my way, heh heh heeeeh(sinister laugh?)......:), Jim

[GearHd]

Does anyone know where I can get new o-rings and nylon washers to rebuild the Mugen Big Bore shocks? Mine are starting to leak and im looking for maybe an online shop to order them from. I also need some oil as well. Thanks

[winning edge designs]

This just in, MBX5 wins Region 4 race in Jacksonville florida! Tooting your own horn is so wrong, but someone had to let you know, right?

GearHD, try superior hobbies at thier website using the same name and the dots and coms, etc.....Jim

[mbx5]

hi people


where's the best place to buy mbx5?

and where's the best place to get parts???


thanks!!!

[winning edge designs]

There is probably no "best place" for everybody. But i've had good luck at two places, Superior hobbies in Casselberry Florida, 407-834-9299, or they have a website. Also JR Hobbies in Kissimmee, Fl. don't remember the number off hand, but they have a site as well, you can find them by doing a google search....hope this helps, Jim

[Shakedown]

I'm currently shopping for a steering servo for 1/8 buggy.

What's the minimum torque requirement for one of these and what is fast enough?


Interested in these right now:

Hitec HS 5925 & 5945
KO Propo 2344, 2343, 2174, 2173
Futaba 9350, 9451

Are these good choices for 1/8 buggy competition?

[winning edge designs]

Shakedown, any servo with about 100 oz. or more will be great, for serious racing. But, for less serious club racing, etc., above 85 oz is acceptable. Most racers won't notice the speed difference between .12 and .16, etc. so it isn't as much of a concern.
I use a Airtronics 358 usually and i've had good luck with the JR digital servos as well...not much luck with Hi-tec though, but that's only my opinion, Jim

[mbx5]

thanks winning edge design

i only find Superior Hobbies's web site and can't find JR Hobbies!

i don't race at all! i just bash! sometimes i think it's a waste to use a MBX-5 to bash!

what do you all think?

[SN VipeR]

I agree. I wouldn't even bash a Hyper nowadays.

[2Fast2Fury]

hi people


where's the best place to buy mbx5?

and where's the best place to get parts???


thanks!!!

I got mine at All-Star Hobbies in Atlanta, GA. Check out their website www.allstarhobbies.com ....they have it on Sale even cheaper now from when I bought mine. I am very happy with their service.

[jmm]

www.MBX5Parts.com is a good source for parts and hop-ups.. There's a package deal on there to upgrade to Pro-Spec..

[2Fast2Fury]

Thanks for the link...

[SN VipeR]

Does anyone know whether the bump steer issue has been resolved on the new Prospec respectively its ackermann link?

[rc10gtisthebest]

If it has the 5mm one, then yes it has.

[Breakin2]

I recently bought an MBX5, but haven't opened the box yet. I can still return it and get the Prospec or 777 sp1 or the Xb8 or...... Anyway, my question is - is the MBX5 a real step down from the fully optioned cars that I've mentioned? Would it be in my best interest to bring it back and save up some more for the more expensive cars?

[Booyah]

MBX5 is one awesome car out of the Box! I went between the X5 or the XB8 and I went with the XB8, so I could have a differant brand out there racing. The XB8 is a top notch buggy as well but I dont even have mine yet!! SHould be here this week. Hope I made the right choice between the 2:))

I would keep the X5 and just add a few hopups as you see need and have fun! Heck I paid 650 and you only paid what......469-499 for yours

[Breakin2]

Very good point!

[rc10gtisthebest]

X5 basically innovated alot of the options going on buggies today.. ie; Lay down servo, milled chassis for lower components, etc...

[SN VipeR]

Joining the Mugen fraction...

http://mypage.bluewin.ch/www.snviper.ch.vu/prospec5.jpg

Will be adding more pics and some mods to my site as I finish the car.

Breakin2, you can get the Prospec hopups from www.mbx5parts.com when you feel the need to upgrade them or the stock ones break. I'd say the normal Mugen is just as fast, but the Prospec is a tank.

[VMach]

Anybody running the mugen 2,000wt or 4,000wt diff oil in their diff's now? I just bought some and Have to wait till mid January to get a race in with it. I've changed my oil's to 4/5/2 but have an extra set of diff's all ready to put in the car. I had been running 5/7/1. I'm looking for more off power steering entering the corners.
