This motor is a beast! I dropped in a 13T on a 54T spur with the rear differential upgrade. Also, big giant trenchers. I got a couple runs out of the motor and then the 13T snapped! I'm thinking the trenchers might have been a wee bit too much. BUT! I ordered hardened Pinions and now it does wheelies!!! wow... BEAST of a motor... OH, you're going to want get some 6000mah batteries.
