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

Temperature protection: When the temperature reaches 95 degrees C, the speed controller will slowdown and the output will reduce to 50% and the on board LED will turn on. You must move the throttle stick to idle position to reset the speed controller and will 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.

This allows for a more custom match to your plane and the most economical method of production. We will contact you with any questions about the batch number of your plane to make sure we get an ideal fit for you. The complete process from time of order will take about 8 weeks.
