I have just rebuilt my ball diff that came in my Ultima.

To my surprise this ball diff is so crude in its design. Has no polished drive rings and no thrust bearings just rides on washes.

Is this right or have i got a dud diff.

Thank you.

Are the RB5's any good?

so i bought a kyosho alpha it should be here this week and have been told to get a tuned pipe was wondering if this would fit

onto this

and is there any other easy hop ups to make it go better

thankyou for looking

Question for the Kyosho knowledge people. :)

Anyone knows if the hinge pins on the Ultima, Turbo Ultima or even Ultima pro are different in diameter?
The reason I ask is because I replaced the arms of my Turbo Ultima with new ones and now I...

What are the best ni-mh packs to use these days? I heard venom packs are garbage, but every time I'm at the hobby shop the guy is trying to sell me a venom.

I picked up this Turbo Optima Mid Special off a local online auction site for pretty cheap.
It was sound and mostly complete,but still a little rough around the edges.
I'm pretty sure this was originally sold as a complete kit,rather than one of the...

Red one I raced blue one was back-up they were restored and became shelf queens I couldn't find original decal used MP5. Lots of hop-ups. O.S RXB's

Some of you might have seen this on other forums, some may not so I thought I'll post some here, sorry but no video on this, but I once ran it with a 1/8 scale Porsche 356? with Duratrax on road tires I estimated at least 70 mph or more anyways air...

just finished a long term Optima Mid project. I received some used Mid parts in a local lot find (enough to complete about 70% of the car) five years ago and was determined to keep this project on low budget, hence the long time it took me to...

I raced dirt oval back then.

I customize a top plate and shock towers using G-10 added a .21 tank for extended run times.

I used a cut down .21 18 tooth to fit the .12, was fast down the straights. I had better luck with the nylon spur gear...

Guys,

Aside from drilling two holes at the front T-bar attachment point to add tweek screws, how are you supposed to adjust the tweek on the Kyosho Plazma MKIII? I have a copy of hte instructions, but they are only in Japanese.

Any advice would be...

I need one M3 x 45 bind screw to finish putting the motor guard on my Kyosho Turbo Ultima. I had one (but I needed 2) and I have several that are M3 x 40, but I'm missing this one. Any advice on where to get one?
Thanks for the help!

I posted these on the Tamiya Club over the past several weeks, but after finding this site recently I figured I'd share here as well. All three cars were torn down, cleaned up, and refurbished. I placed a few new parts here and there and all three...

So I found some pinions in the 50% off box at the LHS. They are hard ano Kyosho. Question is what pitch are they? I have a 19 tooth 48 pitch pinion, which I assume is US 48 pitch (p/n W0119). There are several others I picked up, but they do not say...
