TL 01 Pinion Gear ?

[chem]

Does anyone know what pitch pinoin gear I can use for a TL-01. I used a 23t 48p but it would'nt fit where it was suppose to, motor mount wise. I tried it on the 21t setting and it stripped the gears.

You can only use Tamiya pinion gears. They are 42-pitch. That's why it will strip the gears.
