From my experiments, the in-flight flap reflex position is a function of required CL which in turn is related to weight, TAS, and density altitude. I can change my flap reflex position by 2 deg. which will change TAS by 3mph; I've done this over and over. This is due to the relationship between parasite CD and camber of the NLF1 0215F airfoil. Use maximum reflex when fast, light, and low, and reduce it when slower, heavy, and high!

You Bet, Paul.

 

There are not too many airplanes that give one such interesting control over the performance by changes the shape of the wing thru flap positions (uh, this includes trimming for ugly CG problems). Other flapper-doodles are only designed to assist in the Cl at approach/landing speeds.

 

We are lucky to be flying one of the more interesting wings extant.
