This video contains some excellent guidance for external mounting of an action camera.

Just got a GoPro Hero 5 Black for Christmas. Still figuring out how to use it but wanted to re-visit this thread and see if anyone has any recent ideas on mounting to my Cessna 182B. I went to "cloudbaseengineering.com" web site and looks like a good option. Anyone have any additional ideas or comments would be much appreciated??

Thanks - Dave

I'm just an uninformed spectator, but the guy who made the video below seemed to have taken a flat gopro mount (pic below), countersunk it in the middle for an #8-32 machine screw, used a hole placed in the center of a inspection panel (who knows how it got there) and then put a washer and nylock nut on the backside of the inspection panel. It could be inferred (from the video) that the inspection panel could then be moved around the plane's many inspection panel locations (7 per wing on a cessna 180), giving many possible video angles. If you were to leave the backing on the adhesive, you could then rotate it around as desired for the perfect angle before tightening the nylock. Or at least that's what it looks like from the video.
