NOT FOR SUPER BEE!!!
Add the Buzzer to enable the audible alarm feature of the Killer Bee. The Buzzer will sound when you have left the receiver power on and turned transmitter power off, which will keep you from damaging servo's by leaving the receiver in failsafe mode. The Buzzer will also sound when the engine is killed, reminding you to flip the 3rd channel switch on your transmitter. Not compatible with the Super Bee.
