I think this looks cool as shit too, but I am Leary of it. wouldn't there be too large of a lag time from pressing a bottom on your phone to make a maneuver to the time that command gets to the aircraft? Also, they make that thing look incredibly stable while in flight. I fly rc helicopters and it's a PITA to keep that level of a track and do some of the thing they did especially over a phone with the aircraft not even in sight.......
It almost looks too good to be true in the videos. I would have to try this thing out before I ever bought one.
