Bye Aerospace’s electric Sun Flyer 2 successfully completed the first official flight test with a Siemens electric propulsion motor February 8 at Centennial Airport, south of Denver, CO. The Sun Flyer family of aircraft, including the 2-seat Sun Flyer 2 and the 4-seat Sun Flyer 4, aim to be the first FAA-certified, practical, all-electric airplanes to serve the flight training and general aviation markets. Siemens will provide electric propulsion systems for the Sun Flyer 2 airplane—the 57 lb.-SP70D motor with a 90kW peak rating (120 HP), and a continuous power setting of up to 70kW (94 HP). The 50th anniversary of the Boeing 747 will be celebrated at EAA AirVenture Os
