okay.....

both wings stripped and glued together using the aluminum joiner tube. The only thing I would add to this process is to pre-glue (epoxy) the surfaces of both opposing root ribs, let dry and sand with 400 paper. By doing this, you decrease the effect of the epoxy getting soaked up by the wood thus making a stronger wing joint. I also used a larger diameter and longer rear rod than what was supplied in the kit. Once the wing joint had dried, I dry sanded the entire wing using 400 grit paper dry. The wing skins are already very nicely done, but the 400 makes em that much smoother to accept the fiberglass cloth later on....

With the wing sanded, I set about re-enforcing all three joints. Yes, ALL three. The outer wing panels are only held to the main center wing via a plywood doubler spar. The leading edge, trailing edge as well as the wing sheeting is butt-jointed against the center section. For this reason, I used carbon fiber tissue plus polyester resin using a small epoxy/resin brush. Use the brush in a way to force the resin through the carbon fiber into the wood beneath it. For your information, I tested this tissue on some scrap balsa butt joined together and the strength achieved once the resin has cured is phenomenal. As can be seen in the photos, I sanded all three joints, particularly the outer two to create a blended appearance.....
