While the 30% is true they've only delivered less than 10 planes so far - they kept having production delays and have over 100 backorders to fill.
It's the third overall crash, and second fatal crash in 6 months, the previous fatal one the pilot was the guy who actually designed the plane. The first fatal crash was ruled pilot error (they flew into a canyon surrounding a lake with only one exit and no room to maneuver - the investigation concluded that the pilot thought it was the next canyon along that had 2 exits).
You don't need a full pilot's licence, or a runway, and you can transport it in a trailer as the wings fold up. It's also much cheaper than a standard plane. Unless this crash ends up being a mechanical fault, as crazy as it sounds, I think the publicity and raised awareness of the plane could help sell more of these things.
