The machine is called a Doodlebug. Basically a powered hanglider. No problem with the wing size. He was indeed constantly on the edge of a stall. I think he realises how lucky he was to get away with it and is seeking instruction.
Hi Leigh at el!
The last time I flew one I jumped off Laugna Mountain (4800' +) off for the Salton Sea.
Hit a rotor draft then a down draft... lost 3000+ feet (no altimeter) but only recovered at about 50' above the ground! Really thought I was going to go SPLAT! Then the adventure really began trying to get the ground crew to find me in the middle of the bad-lands!
