Sportflyr,
I controlled the camera panning with a knob on my 9C. I converted a Futaba S148 server to 180 degree rotation. They're cheap and fairly easy to convert and better than a retract servo because you can't stop a retract servo anywhere in its rotation. I set the end points for the servo in the transmitter (just like you would on a control surface) and hooked it up to the TV to check the positions. I was alone at the flight line while the rest of the guys huddled around the camcorder to watch. I didn't fly-by-video because this plane moves too fast. I have flown my 80" Cub from the video alone. That was cool. Took off and flew around, but landed with my eyes on the plane.
On one of my earlier flights, I was able to follow a fellow club member's B-25 for a few seconds. Its very difficult to get right behind another plane and maintain a safe distance unless you fly-by-video. I'll practice at that. A club member owns a "repaired" Lancair that I am considering buying it as a camera plane. About 8 inches of each wing were broken off and they weren't repaired straight. I might "clip" the wings and see how it flies.

Thanks for the complements, guys.
