Watt-out-put limit: The output is rated at 388 watt. Under this watt, the speed control will work normally. When the watt approximately reaches to 410~420, it will automatically shutdown to prevent the over load to the speed control.

Temperature protection: When the temperature reaches to 95 degree C, the speed control will slowdown and the output will reduce 50% (the on board LED will turn on). You have to move the throttle stick to idle position and then the speed control will re-work once you throttle up again.

DO NOT install a motor which rating is larger than the speed control’s limit to avoid damage or burn down.
