ah......that would explain the extreme torque and not so 57mph top speed, but should i keep it in 1st? my gearing is very high (66t spur 21t (i think) pinion)
i would go in the opposite direction and lock it in 2nd, but gear down. waaaaaaay down. i found novak's recommendation of 70/12 or 70/13 tops (on 7 cells) to be about perfect at keeping motor, esc and battery temps all within the right range. with your gearing, i'm really surprised it hasn't thermalled yet. :036:
