Thanks for the comments, actually it's not a zagi at all. Its called an X-ITE combat wing. There are more details and photo's on my website.

I don't think you could see how I was standing on the video but I was on a sand dune approx 15ft up. When we get a westerly wind coming of the Irish sea it can get very very strong. You are correct the way I fly in this is to throw her up and then just cut the motor off or turn it right down. She will quite happily hang there in a breeze that strong.
These planes are just awesome and whilst everyone else is sulking I am out getting a fix.
