Bye Aerospace announced that it is in the process of installing a Siemens motor in the two-seat Sun Flyer 2 proof-of-concept, which first flew in April. The 90kW motor provides the equivalent of 115 hp, which will power the all-electric airplane to 135 knots, said Bye Aerospace’s president and CEO, George Bye. Power is stored in seven massive batteries, five in the nose section and two in the back.
