alright guys I'm having a problem with a couple motors. I have a 7.5 and 7.0 that are acting up, both of them malfunctioned in similar manners, come off a jump kinda sideways, pull the throttle and nothing, so when i went over there to see whats up and i pull the trigger again all you hear is a high pitched sound and then the motor literally smokes. I originally thought it was the sensor board, but after today i don't think it is. A buddy said it sounded like a stator but i haven't learned enough about the motors yet to know. I have switched the sensor board to a different motor and its the sensor because it worked fine. After retesting the 7.5 today just on the table hooked up to an esc no gearing, not moving a car the engine smoked again and it got to 107* in about 40 seconds. One thing i did notice is if felt like there was a slight vibration that i could feel while holding it.
