RE: sorry
I had that problem with one of my wings too... I pulled the fiberglass tube all the way out of the wing and put a light coat of polyurethane glue on the tube then slid it back home. It seems to be holding just fine.
I don't know if you'll ever get rid of all the wing slop...??? [&:] My Sig SE did the same thing. Just my opinion, but I think the 2 wing half on a tube design is just bound to get sloppy over time (unfortunate, 'cause I love flying this plane). [:@]
