I gave upon a Canon HG10. I've used a Fuji Finepix and currently a Panasonic Lumix DMC-FT12 compact digital on Movie mode. Yesterday I was using a lightweight tripod set in my flightbag, which was strapped in ther RHS. This seems better than a home made bracket for vibration effects. If you have autofocus or autostabilisation, and the camera is shooting through the prop, you can get weird effects if the prop synchs with the camera sensors. I don't get the prop effect with any of the three, but the Canon stored to a hard disc, and was too sensitive to vibration.
Replace the Instructor in the RHS with a suitably secured flightbag.
