When the controller signal lose, it will stop automatically. But it will come back to the former mode at once when it receives the signals. It can be used for electric planes, helicopters. And it can be positive and reverse by adjusting the motor lines. Introduction in using: 1.please insert the signal lines in correct direction to the controlling output port of the controller.

2.please connect well the three output ports of the activator suitably to the three input ports of the brushless motor.

3.please add the relevant voltage to the electricity input port of the activator(please be sure the positive and negative poles are right),and you can hear a sound“beep”.When you push the throttle rod, the motor will turn at once. If the motor turning the reversing direction, you can exchange any two of the three lines and it will be OK.

WARNING: If the using current of the BEC over the rating, we advise you use extra BEC. Or it will damage the activator.
