Hi Eric:

No longer satisfied with the Nikon F duct taped to the wings?

Here is an alternate approach to think about. Buy one or more miniature
television cameras. These things can be tiny and inexpensive (some are no
more than the size of a pencil eraser). Then mount one in the front of the
sailplane and run a cable back to your palm computer and use the palm
computer to record photos. You could have a camera in each wingtip and even
one in the tail. Total weight just a few ounces. Switch cameras with a
switch in the cockpit.

Regarding the polarizing filter, it needs to be rotated for maximum
effectiveness, depending upon the angle of the sun. If the filter is fixed,
you may have to rotate the sailplane for maximum effect. Polarizing
aerobatics, so to speak.
