You sure do find some awesome stuff! I seriously need to start setting some more money aside so I may get my hands on some of these things!
I imagine it'd be a case of switching modes using a switch on the transmitter, perhaps he stopped just to quickly calibrate the flight controller?
I read some of the stuff on their site and my questions is one of the FAQ, and it does let you do a rolling take off - should be pretty cool, especially if you're brave enough to drive it off a cliff.
So many awesome things you could do with it... I think I'd get a lot of practice with it before attempting to drive it off a cliff though You could probably do a rolling landing like a fixed wing plane!
