Sorry Michael - couldn't resist! ;-)

But a serious question: opening the link shows a huge color display on the panel. Anyone ever thought about placing a small automotive-style blue-tooth backup camera into the trailing edge of the rudder like the white Nav.-light and providing a momentary switch on the stick which would display the feed from that camera?
This one is a hard-wired one but ....

Automotive back up cameras are too wide angle to work past about 50 ft. We tried one on our 182 towplane that doesn't have the rear window. The problem is that the cameras have over 150 degrees field of view. For the 200 ft. back to the glider, we used a 90 degree lipstick camera.

The automotive mirrors are too convex and you won't see anything past 100 ft. I used bicycle rear view mirrors that have a very mild convex component to them. I wouldn't see the traffic coming up behind me, but when I'm thermalling and I knew that someone was behind me, I could see the other glider that was in my 4-8 o'clock position.
