I have always worried about this, if it was a helicoprer I think it would not have ended so well..... http://youtu.be/YcjeM017rl8?hd=1&t=4m15s 4:15 is just before it happens......
Great video! Agree also. A Helicopter most likely wouldn't have been able to tolerate a encounter with a power line. This guy's quad handled it pretty well.
