OK, wing pictures as promised. Basically it just had on missing wing tip trailing edge block, a broken rib and several loose glue joints.

1. To make the new trailing edge block, I looked at the one on the other side. It is basically a balsa block with the grain running parallel to the span with sheeting running perpendicular on both sides.
2. I had a perfect balsa block left over from an old kit or something as well as some scrap 3/32 and 1/16 sheeting.
3. I glued the sheeting to the new block just like the original.
4. The new block gets glued to the wing.
5. After rough carving with an X-Acto and a final sanding to get the shape right, the new wing tip block is in place and as good as or better than the original.
6. This broken rig needs to get fixed.
7. I could have gotten fancy but I just glued the rib back to the shear web and added a piece of 3/32 balsa to fill the gap from the missing chunk of wood. Not necessarily pretty but easy and more than good enough. I also put a little thick CA into the crack near the front of the rib.
8. After hitting all the loose glue joints with CA, the wing is ready for a final sanding and covering.

Now it is on to stripping the covering from the fuselage and fixing whatever I find wrong.<br type="_moz" /><br type="_moz" />
