Mike, several of Red Reinhardt's Flying Wing Stunt models appeared in Minnesota in the mid-'50s. It was a pretty good flyer as I recall; Fox .35 Stunt up front was the norm.
Don Still's Nobody for combat was a personal favorite. I built a couple of wings with basically the same dimensions but modified structure; they were great "wind flyers". I could keep them up for several minutes after the engine quit, sometimes even sitting down in the middle of the circle.
I have plans & copy of the original construction article for the Nobody for those who might want them.
