Speaking of the above...but keeping it in the R/C realm...
A feature I'd see someone invent for the #11,16 or #18 is a *simple* way to-
1/Power the camera from the flight pack and
2/Somehow be able to get it start/stop recording by using a HK switch using Ch5,6,7,8
That way once you are ready fly, you power up the plane which also powers up the CAM.
Then when ready to record, hit an Aux Channel to start recording.
After landing or the *crash* you can leave it recording for post the mortem until you stop recording by flicking the Aux Ch off.
*Or the recording is stopped by the crash!!*
I know there are already similar ideas floating around some in Tom's Keycam threads, but they are hard to find and complicated to boot.
I might have an try an honest go at creating something when I get the time, and my health improves.
