Thanks brotha that helps. Yeah the thickness of the wing is what had me worried and I was thinking about laying swervo on its side. Figured that way would help with drag a little bit as well. Might just go with one I guess I will just have to see how I feel when I get to it got other projects on the build table right now. I will be using hitec 81's since a that's what I have on hand.jl33fr33 said:All 3 of mine have dual aileron servos. I like it for ease of installation and ability to add in the reflex with programming. The downside is weight of course. The pic shows the different ways I've done it. Since the wing is so thin, the servos have to be shimmed under the mounts. On the orange wing, there are small shims under the mount flanges. On the blue wing, the yellow mounts under the servos are the shims. On the yellow wing, I cut the mounting flanges off of the servos and hot glued them in.
