A rotation speed of 84 km/h was obtained in 184 m of taxi at power of 35 kW. Level flight was attained at 135 km/h by means of only a fuel cell power setting. A new speed world record of 135 km/h and an endurance of 39 min were established during several flights conducted for the Federation Aeronautique Internationale sporting code category C (airplane). Two and a half hours of effective Hight were obtained during these six tests for a Completa more info path of 237 km. The positive handling qualities and satisfactory here engine performances of these six flight tests have led the team to consider these successful flights as a good starting point for further long endurance high-speed flights.
