Here is a video of a BO-105 getting put through its paces. I remember seeing the German Army every once in a while flying these. They are pretty cool little helicopters. This is pretty close to the UH-72 (EC-145) that we are in the process of replacing the OH-58 with. Rigid rotors are pretty sweet. http://www.glumbert.com/media/flash/player.swf?file=aerobatics&autosta There are a couple of notable moments I think. The first is when they put this inverted and do a downward spiral on the rotor. The other is what looks to be a sort of rolling knife edge. It definitely is a plus to have the camera angles from inside the cockpit at the same time. Enjoy!
