I have no doubt that "down" ailerons helped in your case, but I've had the opposite results. Drooping ailerons have lead to erratic pitching on some of my planes, raising the ailerons has resulted in a more solid feel in the air and a reduction in aileron flutter problems. I've also noticed less of a tendancy to tip stall. But I'm willing to believe that some planes and some airfoils may act differently.
