    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.

      | Phenomena 
 | Reasons 
 | Resolution 
 | 
     
      | The motor don't turn after connecting electricity | 1.There is something wrong with the plug of the 
      electricity 2.The battery's voltage is too low, circuit protection
 3.Transmitter rod isn't in the lowest position, circuit 
      protection
 
 | 1.Reinserting the plug of the electricity or changing a 
      new one 2.Charge the battery fully.
 3.Push the transmitter rod to the lowest position.
 
 | 
     
      | Motor running reversed 
 | 1.Connection the three output ports not correctly to the 
      suitable three input ports of the brushless motor. | 1.Exchanging the two of the three lines and it will be 
      OK. 
 | 
     
      | Stopping in midway 
 | 1.The battery voltage is too low, circuit protection. 2.There is something wrong with the pin, cutting 
      electricity.
 3.The output ports and motor not connect well.
 4.Receiving signals break off.
 
 | 1.Charge the battery fully. 2.Reinsert the plug of the electricity or change a new 
      one.
 3.Check the transmitting and receiving; repair the 
      signals to communicate normally.
 
 | 
     
      | Hear a "beep" sound but the motor not running | 1.Transmitter rod is not in the lowest position, circuit 
      protection. 2.The output ports not connecting well with the motor.
 
 | 1.Push the transmitter rod to the lowest position. 2.Reinsert the plug of the electricity or change a new 
      one.
