Rick,
I have flown an Aeromaster with both wings short, swept and four ailerons with two servos in the bottom wing. The plane I flew also has a Saito 100 in it. I really loved the way the plane flew. It was very acrobatic which you would expect with four ailerons and the Saito was a perfect match for it. Also, the man who built the one I flew made a slightly oversized cowl out of laminated balsa to help conceal the motor. He said it was quite a bit of extra work, but it turned out looking fantastic !
Good luck with your plane. You're doing a great job so far......
