July 30, 2007 With rising oil prices threatening to put sports aviation out of reach of the average enthusiast, innovators are looking at how the sport might be preserved for the next generation. Sonex and Aeroconversions are two such innovators and in partnership the two companies unveiled their three-prong e-Flight strategy at the recent AirVenture OshKosh trade show. An ethanol conversion of Aeroconversions’ AeroVee powerplant and efficiency enhancements for the engine took a back seat to the prototype electric Waiex aircraft introduced to an appreciative crowd. With lithium and lithium-polymer-based battery technologies advancing by the day - gaining power, reliability, endurance and efficiency while constantly shedding size and weight - the partners believe the time is ripe to adapt the brushless electric engine for sports aviation use. The AeroConversions electric motor and battery boxes should end up roughly the size of the petrol engine currently installed in the Waiex with a 130mph top speed and 1 hour flight duration expected for the production model.
