Control surfaces for the middle wing are hooked up. I used RG60 welding rod for control rods because I had some extra, it doesn't bend like the piano wire does. Use sparingly because it is expensive, I just used scraps left over from a another project that were too short to weld with. The linkages between the wings will be mounted on spare servo horns embedded in each aileron, but I'm not sure what to make the linkage out of because I'm out of RG60.
