These things are something. Sure fun to watch. So maneuverable it hardly seems real.
There is another video somewhere, (can't find it now), of one outdoors, though it is controlled by a person. Looked similar as I remember. The climb rate was impressive. Powerful, too, especially considering its size. They showed it with a 1 liter Coca Cola as a payload, and it didn't slow it down much.
Thanks for the vid, Dave!
