I recently came across a cool video that I am sure quite a few of you have already seen and yet many of you have not. The video is by alishanmao from You Tube and the helicopter concept comes from the movie Avatar. What the helicopter has is a duel set of rotors, and when you have a look at this video you can really see how similar it is in characteristic to a coaxial helicopter. Now just imagine the stability you can have once you have your digital camera attached to it. Anyhow, the idea is not mine but you have to admit that it is really quite awesome. Enjoy the video.
