Mini Racer 95,

No problems.

Jim,

Are you purchasing your 3Racing tyres as prebuilt units? Or are you assembling them with your own inserts.

Regards,

Calvin.

Austin, stick with the Tamiya diffs. They work and they're "legal."

Calvin, I'm buying the loose tires. They come with a cheap, soft foam insert that seems to work well enough. It would be interesting to see how they work with different inserts though.

Jim

Perhaps the balls get flat spots when they tensioned down. This is using only the balls provided in the ball diffs.

I am trialling a tight gear diff for now. This appears to remain smooth after many runs.

I did work experience at school with Titan motorsport. They make car performance parts and when i was there i found that normally its the other way round. The system will run better after being run not when brand new because there are machining tolerances when things are made. When the parts are assembled they may be 0.1mm too big which may not seem like alot of difference but with car parts and all the tolerances adding up it can be quite a difference. When the parts are run a couple of hundred revs such as when you start the engine the parts will wear themselves out and fit perfectly and run smoother. Perhaps on this smaller scale they dont wear and run in properly compared to full size cars and almost jam up a bit. I dont know much about mini racing but maybe if you continue to run your rougher diffs they might smooth out again as they wear down.

Does anyone know the part number for the larger cone washers in the TA03 ball diff?

I find this to be true of my gear diff, as the part wear into each other it really smooths out.

But in a ball diff for any RC car, it seems to get grittier over time and loose it's smooth action. this may be because a any small grit can get into the ball diff. and even a .001 mm difference could be felt.

The plastic MO5 knuckle is of a completely new design and has the arm located towards the top of the knuckle.

hey calvin,

Jim,

Thanks for the info on the three racing tyres. Might have to try a set for carpet.

edwintklee,

Yes they are the same knuckle. The extra parts in the packet are different. The MO3R front knuckles come with steering linkages, the MO5 do not.

Mini Racer 95,

Yes 3Racing make an aluminium front and rear lower arm for a MO3. Part numbers: MO3M-03/LB Front: MO3M-10/LB Rear.

Or you can get Spice/Tech Racing one piece plastic arms: Spice Part No SPT-303. This comes with two front and two rear arms.

The only consideration is that some events will not let you run these parts as they are not made by Tamiya as a Hop up.

Regards,

Calvin.

Default Carpet tyre question

On carpet I use the Tamiya radial S-Grip (front #50684) & M-Grip (rear #53254) with success.
I'm curious to know how the Tamiya slicks perform on carpet because I happen to have a set of Tamiya Super Slicks (#53222), 60D slicks Type-A (#53340) & a set of slicks which look smaller in diameter #53215.

Can someone tell me please if they have had any luck on carpet with these slicks and maybe if they are perhaps similar to the above mentioned radials I use?

John
