I dunno man, that thing looks like it flys as well as a set of car keys.
No power (well not enough to speak of)
Flys like a Gooney Bird (ass backwards)
How do they stall test it? Spin test (HINT: Don't even think of spinning this thing-looks like it takes to flat spins like a duck takes to water).
It's a neat idea, I like the concept. But the actual flying of the thing I'd leave until it's been in the air for 10 years and the ADs are all out there.
Does it have a built in parachute like the Cirrus? Solve a LOT of problems if it did.
