Project Started (10th scale tourer ..mph ) hopefully
 

1/10 Scale Tourer- Schumacher
12.6 v LIPO
QUARK 125B controller
Lehner 4200 Basic XL

What other suggestions such as pinions would anyone have for me in comepleting my quest....

Start with 75T spur and 17T pinion. If you can use a 45T 32 pitch spur and 11-12T 32 pitch pinion, that would be much more durable with the 3s lipos you're gonna use. If you find the motor getting hot at that ratio, use a larger pinion or smaller spur.

Good luck.
