I have seen the little alarms for when batteries get low. Is there anything like that for when your plane goes down and you know the general area, but you can't seem to find it due to tall grass or bushes or such? I am thinking where you would flip a switch on the TX and the buzzer/alarm goes off and you can follow that to the plane. Granted it would only work if the battery did not eject when it crashed. I ask cause I crash alot. I have in the past just used the throttle but would rather not do that.
