Motor still getting hot and cutting out early different prop same battery. I'll go back to 850 75c which has worked so far. Don't think prop choice is causing it. This is either battery choice or the motor is faulty. It does seem to have a touch of odd noise. It has run good so far till now though. Update: same story with 850. I have one spare 1806 laying around. My last attempt until I replace it I cut some venting voles for better flow to the ESC. If that doesn't fix the problem, I think I have to replace the motor.
