What is E-Flight?
In 2006 Sonex, LLC’s research and development team began work on what is now called the “E-Flight Initiative.” E-Flight is a push to explore viable alternative energies for powering sport aircraft and improve the efficiency and performance of current products and technologies to keep aviation affordable for the average pilot, and to keep recreational aviation available to future generations of pilots.
Although E-Flight has been shrouded in strict secrecy to ensure intellectual property protection of its more cutting-edge components, public unveiling of E-Flight at EAA AirVenture Oshkosh 2007 has been a vital key to the Initiative since it’s inception. E-Flight is not only intended as a “push” for the Sonex R&D team, but also to help push the rest of the recreational aviation industry toward similar goals in the interest of preserving the future of our sport.
Development of a proof-of-concept electric motor powerplant, controller, battery pack and charging system with the goal of determining the feasibility of a marketable line of Sonex and AeroConversions products. This project represents the most significant portion of E-Flight, in terms of investment, risks, challenges, and possible gains.
Our endeavor is to not just assemble "off the shelf" components, as others have done before us, to prove that electric flight is possible. Our mission is to develop a truly integrated eco-friendly alternate power system that combines efficiency and safety for our line of existing aircraft, and the future of sport aviation.
