I got to finally go flying Sun. I used a Hy-bred plane. See "Got my jones off" in the Glider and Sailplane forum. When I got the plane trimmed out I noticed that is was flying best with down elevator ( about 5 degrees of trim). I know this is not aerodynamically clean. Which way should I move the wings incidence and about how much? The elevator is 1 7/16" wide x 22" long.
