Blender, I think you just increased the sales of GoPro HD's from Rotorheads with that photo
Regarding your cord trick, I did that on the car when I tested it up to 100mph with the suction mount.
Now just to find out about the FAR's and mounting it.
I guess I could always wear the head mount like a night light, though I won't get the shots like you have in your video.
I have done some neat flying down coast lines, valleys, country side and the African plains, and it would be great to be able to capture those landscapes, from the outside of the aircraft.
