I've ran a Mamba 5700kv in mine with a 2s lipo with no problems:

A 5700kv still might be too much though. I'd stay around 4600 or lower just to be safe :wink: Only thing I reccomend for the tranny is the newer idler gear. It's made of delrin and can take more abuse. Same part#.

Yes:
LRP = 4700kv
Losi = 4800kv
Venom = 5200kv

There might be more but those are the ones I know of. I've never looked but there is a way to convert the Kv rating to a turn#.

Brusheless motors are rated in KV. You can get a Traxxas VXL System (esc & motor) for $149 at tower hobbies. Thats the cheapest "name brand" Brushless set-up I've seen. It's a 3500KV motor.
