I've started the right wing panel. This is a pretty big plane. Work is going slow due to other distractions like setting up a LAN in my Dad's house, etc.

Anyway, I'm about half way through the right panel. The LE and TE are glued in place, but the ribs have not been glued to the spars. I need to jig it up and get all the ribs parallel and square before gluing those joints. Right now there's a lot of lateral wiggle, but once the center sheeting, tip block and rib/spar joints are glued it will be solid.

I increased the length of the three spar doublers in the center section. And I made the middle doubler out of 1/4" birch ply. I will also add ply doublers behind the LE and in front of the TE after the wing halves are joined. It sounds heavy, but I build light: a carry-over from FF building.

1. Dry trial fitting of the parts.
2. The root rib angled for the dihedral joint. The first four ribs are 3/32 smaller top and bottom to accept the sheeting.
3. The three spar doublers showing the 1/4" birch in the middle.

Next: Jig the panel square and glue the spars in place; carve/sand the tip and sheet the center section.
