Sounds like a good idea. Reviewing the flight visually would be a good reinforcement. I have had my golf swing video taped and the replay gave me a picture of what I was doing wrong, much more clearly than the instructor could describe in words. This knocked 6 strokes off my game, so it paid off. The sme should be true of a cockpit review.

If you have a video camera that can be safely mounted, then forget the wireless camera/receiver/recorder. I have a Sharp camera that will accept video from an external camera -which can be a tiny lipstick camera that can be easily mounted. I assume you want to have the view from inside the a/c, and not attached externally
