Thanks for your reply about the hot ESC’s… it helped me understand how the FC controls the power the ESC’s output to the motors. It must be some kind of variable resistor system in the ESC that restricts the full battery voltage from getting to the motor, and that means the voltage that is not being used by the motor has to be converted to heat, right? Seems there ought to be a way to return it to the battery… but, then again, I’m no engineer so what do I know…
