Insane (RC) Flying

The guy operating the remote control in this video is a virtuoso (watch it in high quality if you can). Of course no physical laws are violated - you have a very low-mass, very strong model airplane with a very powerful engine, so flying square corners and such looks weird but is obviously possible (but this would hurt if a human were pulling those G's in a real airplane). But I have to admit that what happens at around 2:00-2:30 in the video is pretty damn freaky. The guy's a helicopter pilot and an airplane pilot. Very cool flying.
