Flawless work and some ingenious methods, too. I really like your idea of using 1/32 ply tabs and rubber cement to hold the ailerons in place. The ailerons appear to be part of the airfoil itself. One thing I didn't like about the Kaos I built was that the ailerons were just balsa strips attached onto the trailing edge of the wing and not really part of the airfoil contour. Have you weighed your wing at it's current state with the retracts and servos in place? I'd be really curious to know where it's at before covering.
