New DIY Electric Airplane Takes Flight | Wired
The number of flying electric airplanes (and pilots) increased by one with the first flight of John Monnett’s Waiex in Oshkosh, Wisconsin. The Waiex is one of several models of kit-built aircraft designed and produced by Monnett’s company, Sonex, and the electric version has been in development for several years.
The airplane is a standard Waiex kit aircraft modified with the electric power system. The airplane currently has a 54-kilowatt brushless DC motor and a 14.5-kilowatt-hour lithium polymer battery system. In addition the company has also developed its own battery-management system, motor controller and cockpit instrumentation.
I think this is really interesting despite the limitations with the current battery setup (Aprox. 14 minutes at full power).
