I'll echo what Minnflyer said, you don't need dual aileron servos on this plane. I built mine with single servo and it is more than adequate for what this airframe is capable of and was meant to do! If you haven't already, make sure you check out the Escapade Arf thread for some other tips. Heres a link incase you haven't.
