Yes Roy was the one who bellyed in at OSH. The failure of Roy's doors had little or nothing to do with aerodynamic forces. His doors were alum panels sliding in alum channel. The problem was that the cable used to move the doors was attached at the corners of the panel instead of the middle. The panel, being pulled unevenly from the side, became cocked sideways slightly. This caused it to become wedged in the channel and would no longer slide. It worked fine for him in his many trials at home. But if failed after his cross country to Oshkosh. Jim

saying. The big thing I
worry about with this design is the aerodynamic forces pushing on the
door, making the friction to high to move it. I believe that is what
happened to Roy? Snip |
