Howdy,
Very nice indeed :clap: :clap:
That remind me of the "boucle tranche" experiments done a while back.
Saw a Toon almost performing one (I'm sure there is a video / report somewhere), and on top of my head, I think Pierre Rondel did it with a Voltij, but he might be able to confirm.
Another cool thing that came from these trials, is the "Falling Knife Edge", where you put the glider on the KE, and fall vertically
As demonstrated in this Exca" Vs Voltij video (somewhere near the end)
