hi to all! im new to this and i never had, tried, touched, any of these RC helicopters before, but the one thing that intrigued me the most is, how do these RC choppers maintain its 3D flights? especially flying upside down? i just saw one video of lukas riva flying his trex 700 (http://www.youtube.com/watch?v=4pjjC83PTJQ) and its unbelievable. can anyone enlighten me regarding this please? the physics and aeronautics of it, thanks! i tried googling but only come up with videos and guides where they just teach or ask you to try with simulators but didnt explain why or how, wherelse most would say its impossible to fly a helicopter upside down. but the video showed otherwise.

thanks btw.
