Will bring a copy of the TT02 Gear ratio Chart I have so you can choose what you need. It does depend on where you are intending to race the car. The ratio for indoors is different for the ratio for outdoors. Not sure what spur the TT02S comes with but if it still has the original Tamiya 0.6 module one I would suggest you change it for a normal 48dp spur as this will give you many more gearing options. I will be running the TT02 again on Wednesday so can go through it with you if you want.

Looking at what we are running in our TT02s we have 74t spur and 30t pinion giving an FDR of 6.41 for indoor racing. Both of these are of course 48DP and NOT Tamiya 0.6 module.

If it is a 70t 48DP spur then a 28t pinion would be OK for indoors.
