how hot are your motors getting

[dodgydiy]

as per title really, how hot are your motors running and on what setup, with what cooling?? i ran my losi8e on 4 cells to give it a try, intending to try six cells now as the 1400kv motor is far more suited to higher voltage, 14 tooth pinion, after ten minutes you could just hold motor, felt very hot so i am a little concerned that motor temperature may get too high with the extra 2 cells on the same gearing. car was too slow on 4 cells, about the same as a tenth buggy on a stock motor
