Bovan,

I learned this technique from a good friend while trying to get a couple of warbird kits to fly better. They all tended to stall at the root of the wing prior to the tip. The sure way to tell if it is stalling at the root is that the plane will drop 3 to 5 lengths before recovery is possible and control is regained. While if it tip stalls first recovery is usually less then 2 lengths. It won't take much up aileron so work in up aileron slowly and evenly. I now do tnis on almost all of my airplanes. Let me know how it goes.

Good Luck
