RE: ARG! Control Surface Horns - Help
My personal opinion is do it the easiest way and fly it. The plane is only fifty some inch wingspan. If you are really concerned about the geometry(equal throws each direction, etc.) just compensate through your transmitter set up. On a rebuilt plane(and I've done a few), there are probably going to be other airframe misalignments that affect the plane more than the control surface hinge line being slightly misaligned from the pivot hole of the control horn.
