hyper 8 heat problem

Lipo shouldnt heat up too much as its rated for 100 amps constant
You will have less problems on 4 or 5 cells. If it got hot on the road you should also look at gearing but definately get a higher cell count battery.

does the car roll easily with the motor out - spur gear will turn pretty easily even if there is minor binding in the drive train
