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.

in RC or unmanned simulations ... we can do alot of things that manned ones cannot do due to safety reasons
also power to weight ratio and other factors ...
having said that ... i am sure todays technology are able to create REAL HELIS that can fly like the RC ones .. but for what purpose ?? cost vs benefit cannot justify .. and 5-10 mins flight time takes u nowhere ... hahahahaa
welcome to the rc heli world ... i am a newbie myself but i am taking the initiative to learn whatever i can
crashes and repairs are part of the hobby .. unless u are god gifted genius with rc helis laa .. hahaahhaaa
do not be afraid to ask ... well .. u will not get much answers here but there are alot of other forums where ppl are more technical and knowledgable and willing to share
LYN is more of a local share share whatever u can place i suppose

good luck and happy flying !! hehehee
