E-flight
editAt AirVenture 2007, Sonex Aircraft announced a project to work on innovative technologies in aviation. The E-flight projects includes using an electric motor, ethanol-based fuels, and other power plant alternatives.[10] In December 2010, an all-electric Waiex was test flown from Wittman field in Oshkosh, Wisconsin. The aircraft was flown with a 54 kW (72 hp) brushless DC electric motor, managed by a newly designed controller. Power is from a collection of 14.5 kW-hour lithium polymer batteries, giving the aircraft an endurance of one hour at low-speed cruise or 15 minutes of aerobatics.[11][12] This was the beginning of the development of the Sonex Electric Sport Aircraft.[13]
