what ESC?

What is the purpose of using a torsen for the CD? Since it sends the most torque to the more unloaded end (opposite from a normal CD), wouldn't it function much like a solid center shaft (depending on fluid viscosity of course)?

I want it to lessen wheelies and I run on a tight track and the front wheelspin will help.

Good choice on the motor. You won't need a lot of AMPs for the Mega. Here are some options:

well im leaning toward the quark because it can handle 6s (if i ever decide to go 6s) and its only $125. i know how smooth the quarks are and i liek the free replacement! ill put a fan on it. (would a fan be enough? or would heatsinks be better?)
