Here is how the WIG with foldable wing is going. The wings are getting better but slowly. I'm back to the smaller scale and am now using the cardstock wing ribs instead styrene supports for the front to back part of the wing support. I've thickened the ribs to 8 ply to get the stiffness and adding an edge strip that covers the hinge wire. The wire is now fixed within the rib so it doesn't rub against the paper and tear it. The rotation of the hinge is between styrene and metal. It no longer has metal rubbing against paper or fabric. The wing has been blackened with a Sharpie. I'm working on the stretchable skin out of nylon socks. I tried laundry starch to stablize it, so I could use a sewing machine. It worked so so. I've now bought water soluble stablizing paper that is normally used for quilting and embroidery. It can be run through a printer. You pin the fabric to the paper, sew through both and then dissolve the paper with water. I'll let you know how it works on my next interation.
