I tested my vtx10 with a tekin 17.5 today and it was noticeably faster than with the viper 17.5. So I am thinking I got a dud motor. How should I go about replacing that?? Only problem with the tekin though; I kept thermaling the motor. Esc temp protection set at 220*, the can was reading 150*, and it was only 80* outside, I'm scared what will happen when it is 100*. Is there really that much difference between the inside of the motor and the outside?? And what would be the max I should set the cutoff for to ensure the motor doesn't cook??
