Get yourself one of these, they are the dogs..
Works like a G-Cramp that you attach on to which ever piece of the cockpit you like, has a screw thread on top which will screw into your camera tripod mount.
Mine lives in my flight case and along with my casio compact (Z1000) produces excellent videos.
Not sure if it would be man enough to hold a full size vid camera .
