No argument here, Paul, your post is right on! I might only add that besides increasing the drag, and therefore the adverse yaw into the down wing, trying to pick up the down wing with a downwardly deflected aileron increases the angle of attack of that wing. If it ain't stalled, but is very close, when the aileron goes down the increase in AOA for that wing will kick it over the threshold. All the additional aileron in the world after that will only make matters worse. Dan Schaefer
