Picture of almost complete plane. I changed the method for attaching the bottom wing from a couple of small screws, which were very inaccessable to the "O"ring attached to a couple of cup hooks I made from 10-24 "eye bolts". I removed the MM blind nuts in the wings and replaced them with 10-24's, made the eye bolts, used a 2 inch "O" ring to capture the wings. Should work well.
