CAFEENMAN< THANKS for the geometry lesson. The fact is simple, when I'm on final with my coupled flaps, you can actually see the difference in low speed handling VS a no flaperon landing. I do not subscribe to using a predetermined flap "kick down" via a switch, to be smooth and gentle for all flying conditions nothing beats being coupled.to the elevator. I even saved an airplane with a stripped elevator servo by flying in flaperon mode. I had no pitch control otherwise. With a moderate amount of flap travel you transform a stunt wing into a trainer wing, and that is having the best of both worlds. A well balanced setup can actually be "groovier" in level flight than elevator alone, just ask the controlline stunt guys. The AOA change produces a NOSE DOWN tendency in a properly setup system, the center of lift shifts aft. As far as those of you who fly "REAL" airplanes are concerned, my DAD who flew 84 missions over GERMANY in a P47 and had considerable stick time in a P51 after the war wonders if you move your lips much when you make those ZOOMING noises while you fly your "REAL" planes?
