I used half the normal dihedral. I cut away about half the trailing edge where the ailerons would go. I started the ailerons about 1 inch from the wingtip and ended about 1.5 Inches from the center of the full wing. If I were to do it again, I'd start the aileron about 3 inches from the wingtip.

I used 3/4" aileron stock, and hinged with normal flat nylon hinges. It's tricky to make sure they are all in-line. If they aren't the aileron tends to bend as it moves up and down. I can only guess this would be bad in-flight!

For the linkage, I used a Dubro 1/2A Aileron Linkage.

They are controlled by a single servo. I'm using an FMA S-100.

Servo is installed in the bottom of the wing. Torque rod "bushings" are embedded in the remaining part of the trailing edge.

One half of the wing shown. You can get an idea of how long I made the ailerons. I've been told not to extend the ailerons all the way to the tip, as the aileron could cause a tip-stall. If I were to do it again, I'd start the aileron about 3 inches from the wingtip.

A view straight at the bottom of the wing. You can see how far the ailerons extend behind the original trailing edge. I don't know if this has any impact on performance. In it's role as a trainer, it's still as gentle as always. It does look a little wierd though.
