Veeeery poooooor acceleration.

I've tried 6s pack and the cogging went down a bit and motor's rpms greatly increased, but the problem still exist. It still stutterring like crazy! not as crazy as befor, but the controller is still disarming itself again and its getting somewhat hot.
Is it the pinion gear, you think?
I'm using a very heavy, steel 24T pinion to attain some high speeds with big motors, but this pinion's radius is only a few mm less than the 1950's .
Probably that's the problem?
