I would build the wing around al welding rod and 1/8 al rod. But I think at that point I have a heavier wing. Now I thinking about taking a 24" wing span foam and strapping D F motors to it and using the existing radio gear. Listed as good too 100 yards+. And see what I can do. I have to set up a couple of rx for megabyte and set up what I would like back. That will be when I start altering AA's again.
