IMO, the simple stick is an easy scratch build and a GREAT flyer, very underrated if you ask me. If your lad is even a mildly experienced pilot, he will have no issue handling it, relatively generous wing area and good control authority at a broad speed range with a fat prop and heavy throws. It's my favorite for combat because it recovers from collisions so well, I survived SIX mid-airs in one combat at ff23. Six was it though, seven was too many, it turns out. I mean this thing got spun around like a top and landed on the rails every time.... except the seventh. Anyhow, as far as a scratch build, you can just get an image of the plans and lay it out on the foam with square and straightedge, the geometry is so basic. I bet you could scale it within reason from a photo even

. I made plywood templates and can spit one out in about 90 minutes, less electronics. I built ten for fest last year, maybe 3 made it back. I have no feedback on how it lands.
