You're certainly free to build your plane anyway you want, but I've got to say it -- the idea of "thousands" of planes flying around with the fabric simply glued the ribs sends a shiver down my spine. I've heard that the manual in the early kits didn't specify rib stitching but I had no idea that so many people actually skipped it. In the future I'll be inspecting the wing of any Kitfox I ride in!
I took the Polyfiber course last Spring and when the instructor showed us that weird knot, I thought I'd never be able to do it. But then after a few false starts, I was doing it. She gave us an hour to rib stitch two DC-3 stab's and I probably did four ribs myself in that much time. It just wasn't a big deal. It's really hard for me to imagine that someone with the patience to spend years building their own plane would skip attaching the fabric to the wings just to save a few hours work.
I'm no aeronatical engineer, but even I can figure this out -- without the fabric attached to the ribs, the airfoil becomes a simple elliptical arc, with the center of lift about a foot aft of the CG. I seriously doubt that you could fly that airfoil to a survivable crash. And if both wings didn't miraculously come unstuck simultaneously you'd enter an unrecoverable spin, anyway.
My wings will definately be rib-stitched, using the FAA-approved method, and I hope I've convinced anyone else reading this to do the same. This isn't a good place to be "experimental".
