I ended up purchasing a cheap $99.00 Aiptek Digital Video Camera that records 70 minutes of 720p video to an SD card.

See: http://www.aiptek.com/

I mounted the 6 oz camera ( weight with batteries ) just in front of the wing on my .60 big stick, using a small light tripod head.

I had thought about putting in another servo to rotate the camera in flight, but I didn't find this was needed.

I disliked the "tearing" caused by shooting forward through the prop, so I later simply mounted the camera on top of an extension tube made for regular cameras, to move it above the prop.

I've flown this setup about six times thus far w/o problems.

The Aiptek camera's only problem is that the camera "door" must remain open for the camera to be powered. It tends to close in flight due to air pressure.

I ended up disabling the door switch to solve this problem.

A cheap solution which works very well, and I still use that little camera for other purposes too.
