I like it. It seems to fly well. Have you a plan to share with us?

Dave, this is a rendition of the Snowy Owl, [Snowy Owl: Forward-swept Flying Wing Glider for Park and Backyard Flying ] Scratch Built Foamies forum.
It generally follows his design with addition of 2 skins separated by a spar and a full airfoil formed by the spar. Scale the dimensions shown and you are on the way. My plans are sketched on the Fan Fold sheets used to make the plane.

How have a couple of dozen flights. Conventional wisdom suggests tip stalls likely. Quite the opposite so far. Sharp banked tight turns at speed or slow are rock solid. Half-pipes with stall turns at the tops are quite predictable. Stalls are a quick bob with straight ahead recovery. Glide is unusually flat and clean. Power off and back stick increases the rate of sink with no unusual fall-off to either side. No slope time yet, but it gives every indication of being a usable moderate lift ship. The one unusual tendency is slight climb during turns. Comments at the field "It's flying backwards."
