BIG question..... what did you use for attaching the wing sheeting? I ordered another wing from Bob Sealy because I had so many problems with the Dave Brown product. I could use wood glue.. ir thinned down epoxy, but I need to keep it light.... suggestions anybody... just no dave brown junk.
==============
I used 3M contact adhesive for my wing. First time I have used it for the whole wing. If you use the right stuff, it works great, works fast, and is about the lightest thing you can use. I posted a pic of the can way back. It is white and you can get it at auto body supply places. I don't think I've ever seen this at Wal Mart or Lowes. If you need another pic, I'll take another one and send it. This is the first wing I have used this on exclusively since I got back into the hobby in 99. I had been using Elmers Pro Bond, and it works great, gives you time to position the sheeting, but takes at least 4 hours to set, and must be heavily weighted in the core shucks while drying. (or use the bagging method which I have never tried.) The ProBond will add some weight, but if will definitely bond the balsa to the wing and fill any holes between the sheeting and wing. Can be a messy operation though. I also suggest using full 4' sheeting at least on the bottom of the center section of wing for strength. I did this plus added carbon fiber strands across the span of the center section.
I check my pics on the stab and wing and send you something useful shortly. You're right on the stab, it's a little flimsy the way it is. Mine was sort of concaved in on one side. A couple stiffners will do the trick.
