We pulled the last of the coax thru the right wing. At this point, its use is not known. Maybe a second nav antenna. If we decide we don't need it, it is easy to pull it out.
We followed the instructions on riveting the bottom skins. Amazingly, it can be done, albeit with some extreme contortions. We riveted both bottom skins. The wings are about ready to go to the hangar along with all the control surfaces.
Trying to rivet on the stand didn't work well
So we went to flat - and finished the job in about 5 hours
