Tamiya TT02 Thread
#122
I've tried to mount 50T pinion on a 90T spur (ratio of 4.68) and it does fit, but this is absolutely the biggest pinion you can mount.
Gear mesh is a perfect fit.
You even need to use a dremel to get some extra free space directly above the pinion, but this modification is done in a few minutes and it's very easy.
So when you need to use tamiya spur/pinions this is the maximum ratio you can use on the TT-02.

Seems that 46/47 is the last pinion with 0,4 module that fits under the gear cover without touching.
50 needs already quite a good amount of dremeling I guess?
I got my Yeah racing motor mount today,
and installed the longest combo I had: 80t spur gear with 51 pinion in module 0,4. Ratio is 4,08 then. But fitting the gear cover is not possible. Nearly 2mm uplift for the cover. Guess using the dremel would make a hole in the cover.
But with a bit of ABS and glue, this hole can be closed easily.

Maybe I have to try that mod the next days...

It is possible to mount a 48T pinion without any modifications needed to the cover.
I didn't had to use the dremel that much, i guess less then 0.5mm.
The problem you've mentioned about the cover is the shape that doesn't allow the motor to be moved a lot towards the center of the car.
Cause in that case you need to modify the cover a lot more then i did.
I haven't used the yeah racing motor mount yet, but i will do that in the next weeks.

I have no rubbing with my rw racing 49t pinion. The motor cover can warp if you screw it down too much.

I'm loving the TT02 atm with my 17.5 and this FDR it's rapid.
I have a big update on the blog soon I have one more outside race to do first

Hi guys,
Got my TT-02 kit, read a bit of the manual, and will be building it during weekend, just wanna know your setups while building, in the manual there's a 'short' and 'wide' setup, and i'm just planning to go 'wide' and all 'standard' for the rest. Will it be ok or should i go 'standard' all around? And with the 'wide' setup, will the four wheels be too wide for the body shell and looks akward?
Also, is there anything i should know before the build?
I'm just new with this on road thing and this is gonna be my first build.
Thanks a lot for any help i can get.

The manual will tell you what to do to fit with your shell. If you want to use std shells do the standard setting
here is a build review which covers all the steps

Stage one shows where to look in the manual

My little girl drove the TT-02 a week ago in a junior race and she did break 2 steering blocks, luckely i was able to fix them but this is really a spare part you need to have.
They are indeed very weak.
I've also build an extra bridge at the front of the steering arms, this will reduce a lot of steering slob.

ahhh, experience this several times, even on light impact with other car. what i did before changing to alums is i added anti wear grease. So the twist and friction is quite draggy but smooth. added shims on the upper arms so the knuckles doenst wobble on turns. and tightly screwed the bottom part of the knuckle and a .2 or .3mm extra screw space on top.
