I used a Black & White 1/3 inch CAM 3.7mmm bullet camera
(V-1212-BNC) from Marshall Electronics
( http://www.mars-cam.com/optical.html ) to inspect
the spar on my Discus CS. It fit very easily through
the airbrake opening on top of the wings. I also ordered
a fish eye lens which gave very good close ups (2.1mm
F2.0 6-element Miniature Lens (V-4301). This enabled
the inspection without cutting any inspection holes
in the wings.

Connecting this camera to the 'video in' on the VHS
player enabled a tape recording to be made of the inspection
too.

and the
specific instrument you used.
Thanks in advance.
