You could also have a servo that is binding or going bad and drawing too much juice-check for hot servo and see if all servos have full travel and move freely and see if any linkages are binding.Something is drawing too much juice causing high discharge rate and heating battery.If it was the motor,the motor would be getting hot and ESC would heat up.You could disconnect servos from RX and see if battery still gets hot just running motor-if not,then I would suspect bad servo.
