As I have some micro servos on the shelf, I am thinking about installing ailerons on a "Gentle Lady like" 80" glider.
For simplicity, I would like to use the upper or lower surface of the wing as the the hinge line (adhesive tape for hinges)
I am wondering, what hinge line would be preferable from an aerodynamic point of view?
I will also flatten out the "wing ears" e.g. make a single dihedral wing
