The Elio guys sound like Jim Bede and the BD-5!
As for Christmas and his cantilever wings, the original Fokker DR-1 Triplane was to have cantilever wings, but he ended up with the interplane struts because the pilots wouldn't fly it without them.
The Christmas wings look far too thin to be cantilever with the material used and if they were using wing warping for control that means the wings weren't stiff enough to be cantilever. Another crackpot.
