I've built a few like this, and have designed a handful that haven't made it out of Fusion 360 yet.

I have a kit by an FPV pilot (Shelby Voll) that consists of a couple of pieces of pre-cut styrofoam, some carbon fiber rods for rigidity, and other various odds and ends. I think I paid $200 for it. I haven't built it yet, but I've flown friends' builds from the same kit and have built similar ones. It'll take about two hours to build with simple hand tools, and is probably the most durable "flying wing" design of which I'm aware.

I'm mostly into FPV quadcopters, but it seems most people who fly them who get into "wings" seem to prefer them.
