Note: The red LED on the controller will light up for two seconds to indicate proper initialization. After the correct throttle impulse is detected (meaning off position), the controller plays a predefined melody. Now it’s ready to fly. If the throttle impulse is not detected for more than 4 seconds (e.g. after disconnecting the receiver battery), the controller will enter standby mode.
