Castle Creations Arming lockout harness and key with Lanyard

The Castle Creations Arm Lock Key Harness attaches to the AUX LINE (On Phoenix Edge ESCs) and the receiver, and is designed to act as an extra safety measure while operating your RC Heli or Airplane*. When the key is fully seated into the socket, the controller will be incapable of arming. Once the key is removed, the ESC will arm when it receives the low throttle command on the traditional throttle line. If the key is inserted while the motor is running, the ESC will go into the ARM LOCKOUT state stopping the motor from running and preventing the ESC from arming.
