I decided to fill the aileron cove and use Robart hinges at about 20% of the aileron chord. Using a rounded aileron leading edge. Typical horn on the bottom with "a servo per wing" type set-up. I'm cleaning up all of the construction and with the dings and water spots about all sanded off it looks OK. I'll probably use Stix-It to make sure the cover stays stuck in case something creeps out of the wood's fibres.
Pix later, I promise.
