This shows the chordwise pressure distribution of a typical airfoil with a slotted flap retracted, at 10, 20 and 30deg, at both constant lift and at constant angle of attack. Deploying flaps changes the lift distribution across the entire chord of the wing. Ailerons have the same effect.


Twelve radians is nearly two full turns -- per second! I've got a couple hundred hours of stick time in R/C, ranging from two-channel sailplanes to four-channel mildly aerobatic sport models. The most aerobatic models I ever had, a Swizzle Stick and a Terrier, had a lower roll rate than you propose; few pattern aerobatic models have higher (maybe a Zlin or ...
