Running the motor too long is not a problem cause my packs dump at just over 5 mins run time.
In all honesty I don't really have too many worries about the motor being too hot because as i mentioned earlier according to rollout figures I should be pretty spot on with the gearing. I just thought that I would gain some outside opinions on the subject.
My comm is not wearing at an extraordinary rate and the blue on the comm is not very severe at all. It is only a very feint blue and in small streaks. Also there does not seem to be any excessive arcing in fact there is practically no arching until almost full throttle which in my opinion does not seem excessive although I am not sure how much a motor is suppose to arc in normal circumstances.
