Hinge line for ailerons?
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

RE: Hinge line for ailerons?
The hinge line on the top is usually preferred for 2 reasons:
1) This further down the chord the air stream on top is really wanting to separate and any gap introduced would cause it to further separate.. which is bad for several reasons
2) You usually want a smaller down deflection of the aileron than an up (for minimizing adverse yaw)
e=mc2

RE: Hinge line for ailerons?
I've tried ailerons on the GL. Built two wings, one flat, the other with v-dihedral.
The plane flies so slowly the ailerons were less useful than the rudder, so I took them off, and went back to rudder and elevator.
