Well, not sure the camera is going in the cockpit much of the time.
The camera arrived recently along with an additional 25' AV extension
cable, which added $14 to the cost, so it was hard to pass up.
Otherwise I plan also use my second Ram-Mount as a camera mount inside
the cockpit and occassionally through the slider window.
http://www.ram-mount.com/ has a lot of attachment gadgetry, including
standard camera mounts.

For some specialized video, I'm looking a some external mount points.
The camera has digital pan/tilt/3X zoom, but I haven't tested that yet.

There is a difference in the input voltage between the Archos V500 and
the V700. The V500 requires 5V which 4 * NiMH 1.2V 2500mAH cells
provide. The V700 requires 6V input which means building up a custom
holder. I'm ordering a 10-cell AA holder to modify into a 6V 2.5AH
supply for the recorder. Want to keep it self contained for use in a
variety of gliders also.

Wish the taxes were done;^(
