I glue tri-stock too. For the gP G-202 there is a trailing edge cap for the wing. Replace the square stick with tristock that will be thick enough for the ailerons to line up with the center section of the wing. Replace the leading edge of the aileron in the same fashion. For the tail, just add tri stock, and extend the front of the airbalances to make the leading edge of the surface look right. Good Luck-
