Recall that Mark's plane has split flaps, so it's physically impossible for
them to reflex upward (assuming a rigid upper skin).

If you think about it, reflexing the control surfaces up is a way of lowering
the incidence of the wing in relation to the fuselage and more importantly, the
horizontal stab. If your incidence is set correctly to begin with, then
reflexing control surfaces up isn't going to help. However, ref
Yep, I've always thought of reflexing ailerons and flaps during cruise as a
band-aid for a poor design, or some other compromise, although I could be
wrong. I guess everything's a compromise though.
Right now my ailerons are relexed a little. On the ground they are pretty
close, but once in t
