I agree with johnbuckner. If the wing is already built: LEAVE IT ALONE
If it is not built, I would build the B wing and use ailerons. But, I would build it as designed with the single aileron servo. On this plane I do not believe there is any advantage to dual servos. The setup delivered in the kit requires less work, saves weight, saves money, and works fine.
I found on the first one I built that there can be a problem with the control arms getting caught inside the fuse, so I modified my second one to have two servos in the wing. For the extra $20 it cost I think it is worth it, it also makes the plane a bit easier to trim in my opinion.
I set up the plane so that the servos are close to the end of the ailerons, it is about 2 or 3 bays in from the fuse.
