As an amateur flying robot builder myself(airship type, search the forums if interested). I have say the video in this link is awesome.

An amateur roboticist got a helicopter 6 seconds in the air autonomously. Most of people cant pilot those things for more then 3 seconds. Nice job. I think I want to build my own now.
