Another link to that glider and several others. Looks like they've
updated the AC-4 which was in the One class competition and lost to
the PW-5, unfortunately. A bunch of AC-4s were sold in the US. I know
as we equipped most of them.
There was a self launch version also. There's one in NZ.
Stumbled across this today:

That's a very cheap single seat trainer aircraft! From my limited research
it seems to be legitimate too.
Some more detail on the hoverboard. It has an autostab system and can
tolerate one engine out.
