I was digging around for CAD drawings of my own designs and thought of this one: Wiki- JA5 Walrus. I actually know the designer personally as a colleague, we had lengthy discussions of his creation and its merits and weaknesses. It is similar to the Bede in some ways. He did it as a self-education project. The airplane itself had a lot of bugs but with enough tweaking it could have been a kit plane in the Long E-Z tradition. Not many of my colleagues have both designed AND built their own airplanes like that. It's way harder than it looks.
