Hey guys - For hinging, I suggest using the covering hinge. This is when you cut some squares, flip one over and iron them to one another:
And you put these in alternating pairs. I like to have a pair right at the control horn, and then a few more pairs along the surface. Why do I suggest these? They allow you to perfectly center the flight surface, and they work really well. A taped hinge is easy, but can lift over time, or allow the control surface to sit a little high or a little low. We really want the aileron to wing joint smooth with this airfoil, giving better roll authority.
One of my glider elfs jumped in and used a simple tape hinge and my hinges are all sitting proud of the wing. I'll do a little surgery to fix them.
