RE: the prefect platform for aerial photography
JettPilot,
You have a nice plane there. How are your camera and counterbalance attached to the wing? Velcro? One advantage I can think of to attaching the camera to the center of the wing is the ability to use dowels through the fuselage and to have criss-cross straps to hold the camera on. Straps can't be used as easily out on the wing, because they would interfere with the ailerons. Perhaps I would start by mounting the camera to the center and see how it looks. I could always move to a wing mount setup.
