I tried both links given by you tube, neither worked so I gave up. Here's how it should work. I click the you tube link on this site to put the you tube link into my post. Then I go to the you tube movie and click share. I copy and paste that link into this post. That doesn't work.
As for my mount I used the helmet mount supplied with the camera. That mount is curved. I had a buddy fill in the curved part with something like an epoxy so it was flat on the bottom. I drilled a couple holes thru the mount to match up with the screw holes that attach my wing tips to the wing. Rock solid. The mount can stay on the plane and the camera snaps on and off easily.
