Not to hijack your thread but a little different perspective. I fly mostly control line stunt at the moment. The one thing I envy about you RC fliers is that you seem to fly comfortably in wind that gives me problems. My ideal is a 5 mph wind coming from the sun. Most maneuvers are flown down wind, and it is nice if the sun is somewhere else (usually it is not.) If there is no wind you have to take a step or two back between consecutive maneuvers to get out of your own turbulent wake. If you don't do so, the airplane at least gets bounced around and looks ugly. At worst you get bounced into the ground. This has happened twice to me. If the wind is about 20 MPH you can wind fly, launch the airplane, without starting the motor, into the wind, whip it over and there you go. Lazy 8's and loops are easy. I've seen George Aldrich do vertical 8's and overhead 8's wind flying his Nobler.
