At this point I installed the 2nd spar. No pics but I installed the spar then used my square to ensure they remained at 90 degrees to the building surface before gluing.

At this point, everything shoulod be fine. However once again, when I look down the TE of the Ail. It is clear that I have a problem. This pic was taken from the first wing I built and I am using it here because I had a real good picture showing the problem. I believe this is the same problem noutssider has. As you can see in the pic. R2 seems to be sitting to low. Actually, when I put the straight edge on the wing, R2 is 3/16" below the straight edge as the pic shows.
