Connect the alarm between the servo and the receiver, i.e. act as a servo extension cord.
Turn on your TX. and you will hear 2 x beep sound.
Do not move any of the control stick on the TX or simply turn off the the TX. You will hear a continuous beep sound after 1 minute. It will stop once u turn on your TX or move the control stick.
If you ignore the continuous beep sound for around 2minutes, the beep sound will change to a louder V sound. (Same as smoke alarm at variable pitches).
MAKE SURE THE CORRECT POLARITY BEFORE TURN ON THE TX

Re: lost plane or helicopter locator
Interesting. I have built my own lost model alarms, and cannot make them that cheap. The most expensive part is the piezo sound maker, about 6 bucks at "The Source". Then there is the hassle of trying to solder all the little bits together on a chunk of Vero board. Older eyes, can't handle it too well.
The older I get, the better I used to be!
