Yes, I've seen this happen. You may have a damaged chassis where it holds the spur gear assembly in place allowing the input shaft/spur gear assembly to move around too much. Thankfully a replacement plastic chassis is pretty cheap for a TT-01. I've swapped one out in about 1/2 hour.

If that isn't the problem, I've seen a TT-01 have a problem where the plastic black bushing didn't want to seat properly on the spur gear and hold it into place when installed (refer to your instructions). I'm not sure if was a bad spur or if it was the wrong spur. I just replaced it with a new spur from a package of 55t/58t that was labeled for use with the TT-01. Tamiya Part#53665.

The Tamiya F201 spur gears could be used on the TT-01, but have to be slightly modified to fit properly.

The F201 had a 55t or 52t spur, but it should have been obvious that it was the wrong spur because the TT-01 black plastic bushing wouldn't have fit properly.

I tried resurrecting my old tt01r, and I have the same problem. Tried, shimming the input shaft so the spur gear doesn't touch the chassis, but it's impossible, because the entire assembly is "floating". I shaved away about a milimeter of the area where the spur gear touches, and the spur gear didn't melt yet, but there is another problem.

When driven outdoors, rear half of the chassis flexes so much, tiny pebble gets stuck on the spur gear almost every time i drive it. It happens almost every time with high predictability, especially if i drive over a crack on the pavement, so I gave up on the tt01.

Took the car apart this evening and there is a lot of damage around the chassis and spur hub. Something is causing this but hard to tell exactly what. I'm going to replace all the parts and cross my fingers that it gives me the solution.

Okay need some suggestions here guys
I got loads of push when I'm driving on asphalt
What can I do to eliminate it???
I tried a bunch of different stuff, but Im gonna go from scratch with your suggestions
Ive got oil shocks all the way around and run a brushed motor with Tamiya stock tires
That's my limitations for this class (The rules for TCS!)

The TT-01 has a solid rear suspension. The front is play city. Try this:
-install Hard(Blue) Rear Springs
-install Medium(Yellow) Rear Sway-Bar (if you got them)

Good Luck

Thanks! Ive got the springs, Is the sway bars installed on the front or both?

Lopaka208

I think just the front.

GuyIsDamGood

If the chassis is giving you too much Understeer with the harder springs; you can install the Lightest Sway Bar in the Rear(try it).

Hey KA2AEV; I'm gonna try to get to that Staten Island track. But; I/we(my kids and I) can only run on weekdays during the summer. I work during the weekend. I gonna have to take a weekend off; just to race.

I'm looking to upgrade the TT01E with a bearing set. Would I better off buying one of the kit sets or buying the different size bearings needed individually and possibly having spares?

I've never bought bearings for any of my kits before, buying a set for my kit seems simpler. Is buying the individual bearings a better deal, better quality?

Looks like I would need:
5 x 11 x 4 qty 12
8 x 12 x 3.5 qty 4
5 x 8 x 2.5 qty 4

Somewhere like Avidrc.com should have the set pretty cheap. Check there or other bearing sites. The Tamiya set is pricey.

So.. what's the best technique for doing tire gluing? The rollovers at the local black carpet track are frustrating.
