It has been awhile since I have seen anything this advanced and precise with rotors (if ever), watching these aggressive flight tactics for a quadrotor / helicopter is an experience. I would encourage you to check out the vids below and take a look at the rest on YouTube. I need to get my dirty hands on a few of these; by few I mean 20.

PS I'm pretty sure they are self-aware and will soon be taking over the world. Was that a sign that said Skynet? In the corner there?
