1) The servo on top is for the ailerons.
Ah, didn't see them. But then, if you have ailerons why did you put dihedral ? Especially on such high wings. And why the swept wings ? For such a small and light plane with constant chord, straight wings would greatly simplify (and strengthen) construction.
The dihedral is because I want it to be stable. One goal is for it to be able to fly itself for awhile in case I happen to lose the video feed at any point. It doesn't need ailerons since it has dihedral and sweep, but I enjoy flying planes much more when they have ailerons. I did consider not including them, since it would have made it lighter and simpler, but in the end I decided to go for it.
As for the sweep, originally I had a straight wing, but after making some CG estimates, I realized it would probably be too far back. After that, I moved the wing back by 1/2", swept it like you see here, and also moved the stabilizers farther away from the wing, all of which move the neutral point aft to allow sufficient longitudinal stability without having to add ballast.
