speeds... 35 ish??
temps ... 100-120 on the components
foc and center diff w/300k, and not locked(no reverse this way) and mechanical brakes
close ratio really helps the small motor run this truck as well as keeping the 2 spd.(makes it easy on the motor when starting from a dead stop)
wheelies.... no , not even on b-top, but i had the ext. chassis and ext. rear arms and a center diff. which allowed alot of the power to be lost through the frt. tires(diffed out)

center diff may be ok for racing but i didnt take much time to test it much (5ook+ may be better), i got a g3r instead, and sold off the stock chassis version
