Slice or remove the covering hinges, then lay the ailerons bottom edge to bottom edge of the wing, leading/trailing flats parallel, and cover them on that way. (Aileron is actually upside down and trailing edge forward at this point.) Then, flip the aileron over as far as it will go, and hold it in that position while you cover the other edges to each other. The pix show it a lot better than I could ever describe it.
This gives you about 2 inches of aileron "up" travel. If you need more than that, you're in the wrong business.
