Famed aerobatic pilot and aircraft designer Walter Extra has set a new FAI record for time to climb in an electric airplane. According to Extra and Siemens, the manufacturer of the motor used in the Extra 330LE, the climb was 4:22 to an altitude of 3000 meters (9842 feet). That’s an average climb rate of about 2300 feet per minute. The record is a new C1b class for light landplanes but it doesn’t exceed time to climb performance for piston airplanes in other classes. The record applies to powered electric aircraft with a takeoff weight of 500 to 1000 kg.
