Only buy this is your radio system lets you set failsafe positions. As other people have mentioned, if you lose radio control signal you will be unable to turn the alarm on. If you have a failsafe you can set the switch position to turn on the alarm if signal is lost. ( I will set up mine so that the alarm is triggered at the same time as my RTH). If you do not have a failsafe, you can buy another version that you connect in line with one of your servos. If no movement is detected after a minute this activates the alarm.

So I was told this can work on a PPM signal. But which channel would this be on by default to assign a switch to? Thanks

Achtung, der HobbyKing®* Discovery Buzzer funktioniert nur bis max 5,8 Volt!! Attention, the HobbyKing®* Discovery Buzzer only works to max 5.8 volts !! Wird er mit einer hö*heren Spannung betrieben, gibt er bei aktivierten Kanal kein Signal. If it is operated at a higher voltage , it outputs no signal when enabled channel .

I can confirm that, I switched to 5 cell Nimh pack for receiver and the buzzer no longer worked

This thing is useless if you lose a model because of radio signal failure, you won't be able to trigger it with your transmitter. Recently lost a 250 mini quad in some forest because the radio gear failed and would not activate the buzzer. Certainly not a fail-safe way of finding a lost aircraft.

I haven't tried this but you could probably put a relay on this that is held open by a channel on the transmitter, and closes if signal is lost.

Configure either your controller or your RX to send signal to the buzzer in case of signal loss.

Good idea tankd0g, unfortunately Morla I am using the stock Turnigy 9x Tx and Rx which does not have a settable failsafe feature. In the future I'll be using a standard 5v buzzer connected to my Naze32 which will become activated when the Naze senses that the Rx is no longer receiving signal.

2 thumbs up!
Adding only 9g to the plane. This is a worthy insurance to finding your plane should it go down. Can use any spare channel. Good product. Hope I will never have to use it.... but you never know!

Exellent makes Airplanes easy to find after a landing.

I found another nice way of using this little thing... Put it on your Car or Truck and POOF!! Instant car horn!! did it myself and it works nice, specially with guys with a good sense of humor.

I further improvements. Remove the buzzer and let him there instead of the FET transistor. Want a cheap RC switch. Excellent ....
