You could use the same slots if you get the nylon hinges with metal pins. I did that with a Sig Somethin Extra aileron and a Sig Kavalier aileron. I will never use CA hinges ever again with torque rods! Think about it- the rod is glued in the aileron at the wing root area. It has to twist the aileron all the way to the wing tip. If any of the CA hinges get brittle you end up warping the aileron up and down because the hinge resists flexing. Just use some epoxy to put the nylon hinges in. Then, drill a small hole through each side of the hinge and epoxy a piece of round toothpick to 'pin' the hinges into the wing and aileron. That keeps them from coming out if you didn't use enough epoxy, from stresses of flight, flutter, etc. You can cut a small piece of covering to cover the 'pin' holes. The best part of this method is that you can use the same slots, and your torque rod system will not suffer from CA hinges getting old, too much CA, or whatever.

Just my .02 worth from experience with what you are going through.....
