5s vid , Q..how do i lower the heat?

temps were better doing speed runs, esc. 185 and motor @ 185, speed est. 40 mph, but bashing when the v was highest was hot, the esc. got up to 265 and the motor was 160, not good enough to rely on for racing, back to 4s i suppose

would gearing down help at`all? i am at 13/48 and i could get rid of the mech. brakes and go to like 11/48

as a side note, i think i puffed another m.a. 5k today
