I unwisely flew a Zagi in a windstorm in Malibu a few years ago. Wind kept pulling it further and further away, even though I was trying to lose alt, so I decided to firewall my controls so it couldn't turn into a kite. It accelerated into a descending loop and disapeared into a tree in front of a house. Two seconds later (which was weird, it should have been much quicker) is appeared at the bottom of the tree, pulled up (the servos were stripped at this point, I determined) and blasted across their yard about three feet off the ground, probably doing about 30-40 mph (seemed faster at the time, so I'm slowing it down to account for the excitement of the moment) out of the yard, across the street, and slammed into the side of my (at the time) girlfriends car (denting it) and bounced into a construction dumpster next to the car.
I retrieved it. The nose was a little dented, but other then some crumpled ultrakote at the nose and the stripped servo gears (easilly replaced), it was fine. I've flown that Zagi many times since.
Zagi's are cool.
