If you have ever wanted to make your own foam flyer you have to check out Hotwire Foam Factory’s bow cutters. They come in lengths from 24″ to 48″ and make quick work of hot wire foam cutting. I actually made a 3D plane from scratch using their stuff and it was a blast to create something of my own. Wing shape templates are readily available online and software can be purchased to create CAD drawings of wing profiles.
