Here are the wing rib patterns and center section balsa ribs. All the patterns have reference marks to locate spars. I have the CF wing tubes and sockets. They are 0.5" O.D. They will be doubled vertically between the spars. They will facilitate connecting the outer panels to the center section.
The elevator is an all moving 'pendulum' type. The mounting has to be robust and fluid with no slop. The stab will be built around a 0.25" CF tube pivot spar. The spar will be an interference fit in aluminum tubes within each stab half. This spar will be carried by a brass tube bushing in the fuselage. The tube ends were de-burred. The CF spar is removable for inspection. The elevator horn is built up from two micarta parts with balsa spacers. I drilled the large hole in each one first then fit them onto the brass bushing. Once satisfied with the fit they were cut to an 'L' shape on the band saw. The other two holes were drilled while the horn were stacked together on the bushing then they were sanded fair relative to each other. I epoxied balsa spacers between the two horns. The reason was I wanted the stab halves to not have any chance of becoming misaligned relative to each other. Probably overkill. I made two fuselage parts from 0.125" marine ply that carry the bushing. A pin from the horn will fit into tubes in the stab. This pin goes through an arc with elevator control input so I used the pin as a stylus via the horn to mark the masking tape on the ply. Then the arc slot was made using drills and small files. The pin will be epoxied in place, later. The pushrod end of the horn has a plastic bushing through which a small wire passes. The pushrod has a fiberglass tube on its end. The plastic bushing is an interference fit on its end. When these parts were assembled then the wire ends were epoxied to the horns.

Here is the end result with measurements. Last picture shows inside of nose. The release will get let into it, next.
