Camera Shutter Speed Matches Helicopter's Rotor

Camera Shutter Speed Matches Helicopter's Rotor. Strange and funny helicopter that flies also if the rotor seems stationary. The main rotor of this helicopter seems motionless but the helicopter still takeoff and fly. This is very strange and funny and it is caused by the number of frame per seconds of the videocamera are syncronized with the rotation speed of the main rotor of the helicopter.
