I think what you mean to say is "use rudder to keep wings level in the approach to a stall", not "use rudder for stall recovery". Stall recovery is release back pressure, add power. Rudder is used in spin recovery to stop rotation. In the case of my KR, and I suspect others built with the same alignment, using rudder input to keep wings level does not work. You have to fly the airplane depending on how it responses to control input. They give us a test period to determine such things. My KR has the 3 1/2 degree washout in the wing, as called for in the plans, and stalls from inboard to outboard where the nose drops with the outer wing (ailerons) still effective. Using rudder at that point (in my KR) to lift a wing only aggravates the situation. It causes the nose to tuck down. Other KR's may fly / respond totally different, depending on their alignment / setup. Also, in my KR, the stall break is not sharp and it does not tend to drop a wing, just drop the nose and fly straight ahead with the release of back pressure. We are all taught in flight training to use rudder to keep wings level in slow flight / stall. How is that done in a "two control" Ercoupe ? :-) Larry Flesner
