My question is how would you wire this up. Ive got a siren from Radio Shack and plugged it into my receiver and it goes off no matter what position the switch is in and regardless of the % set on that channel in the radio.. any ideas?
But whats wrong with always recording your video downlink with OSD info and if you crash, enter the last known GPS co-ords into ur phone? Then you just walk to the dot on the map. There's also no guarantee if the siren will continue to operate post crash also But interesting thought.
