Max, As long as the ailerons aren't sloppy, you're probably over thinking this a bit. Ideal is to have your ailerons match the trailing edge of the wing, but I have flight tested a number of configurations with reflexing the ailerons up and down a bit. That effectively changes the angle of incidence of your wing and changes the deck angle of your view from the cockpit. It also has some effect on the speeds of your plane by cleaning up drag by making minor adjustment to the angle your fuselage is moving through the air at a given speed. Of course getting them too much out of whack will also affect the drag of the wings. At any rate, having your ailerons slightly out of line with the trailing edge of the wing isn't going to make a significant impact to the handling of the plane and is something you can play with at a later date if you want to try to trim your plane up a bit. But typically, there are much draggier dragons to be slayed. :o)
