I have a "crash beeper" from my LHS. Ive used it on my old 72mhz tx/rx. In the event of a crash...after 1 minute of inactivity from the tx or signal loss, the beeper goes off nice and loud so we can trace where it went. Well now that ive switched to 2.4....it doesnt seem to work the same. Anyone have any experience with making these things work on 2.4ghz. Would we have to plug it into a channel and activate with a switch? If so how do I that?
