Certifying the new Arrow-Copter gyroplane has taken another milestone with this successful rotor and rotorhead stress test. Rotor diameter is 8,6 m. Required speed: 500 rpm. Vehicle was a 7-series, 12 cylinder, 300 hp BMW. All 300 horses were required to achieve 502 rpm at a vehicle speed of 100 km/h. It wouldn't go any faster.
Yes, there was definitely lift. The front end of the car was much higher up than the rear end as the rotor was pulling up and to the rear.
