These two pictures show the whole wing with all but the root ribs installed.  The second picture shows the wing turned around and squared up. The aft root rib must be installed with the wing squared up so that it will fit properly.

      These pictures show the squared up wing in more detail.  The first picture highlights one mistake I made in laying out the rear spar.  The predrilled holes in the rear spar did not match the holes in the rib.  I didn’t notice that I had drilled the hole wrong place until after I went to enlarge it.  It is the only hole in both rear spars that did not match perfectly.  I added a hole in between because the misalignment is quite large.  I will add a backing strip to the rivet in the bad hole.
