Quoted from toyotaboy:I can only see that happening if it's a brushed motor and the brushes are severely worn. Some resistors and diodes may help (don't know the values). I know when I was racing r/c cars, they started doing that to get rid of some of the noise because higher RPM motors would actually interfere with the radio
Not a brushed motor. It's a stepper motor.
