Gray Beard, thanks for the tip. I did find some useful info on the AMA site.

Speed Racer, yes I do fly at the Ione field. It's a great site if you like short, narrow runways! Dick Belden is, to my mind, one of the key assets of the club. He has helped me a lot, especially when I was trying to get a couple of pattern planes sorted out. I did find some articles and a chart based on Peter's work. That's really what I was looking for. As for using knife-edge flight as a test, I have a hard time sorting out what the plane is doing wrong and what I am doing wrong! But I do enjoy the challenge.

For those who think all you need is to balance it at the point on the plans, I have this example to show that is incorrect. I have two WM T-34's that were set up for a disappointing attempt at pylon racing. They have the same engine, prop, etc and were balanced at the same point on the wing, to within less than a 1/16". They have very different flight characteristics. One flies inverted with little down stick, the other needs a lot. One I can get to knife edge, the other will not.

Interesting how a simple question (with a simple answer) has devolved into this thread!
