Thanks I can eliminate Scratches by opening the window. Flying the plane and
taking pictures at the same time may not be safe but with proper trim settings
It will maintain altitude and heading for several minutes.

[ ONote: Richard, I had a friend (Bob Kelsey, Chatham, MA) who died that way,
here on Cape Cod. I now own his banged up Hasselblads. He was a skilled pilot,
and a fine photographer. Doing both got him in fatal trouble in 1987. Google Bob
Kelsey, Chatham Photographer for more. Meanwhile, keep plenty of air under your
wings!
