The following pictures show how ailerons were installed based upon the taffeta hinge.

Heavy duty aileron rods are used.

Drill 3/16" holes to route the rods to the other side.

Use a Dremel tool with cut off disk to cut a slot for the ailerons.

Use a file or sanding block to widen the slot to about 3/32".

Use a razor saw to free up the ends and adjust the slot to allow about 5/16" throw each way.
