Electric aircraft have flown for the last six years at the big Oshkosh AirVenture airshow.  Randall Fishman started the movement in 2007 showing his ElectraFlyer trike, and then flew his ElectraFlyer C, a single-seater derived from the Moni motorglider the following year.  He won the 2008 Stan Dzik Memorial Award For Design Contribution “for the installation of the Electric-Motor power train” and the Dr. August Raspet Award.   Last year he displayed his ElectricFlyer ULS, a twin-boom pusher with soaring capabilities. Others have followed, with Yuneec cruising overhead in 2010, winning the Lindbergh Electric Aircraft Prize (LEAP) prize for the craft’s “significant commercial potential” and “compelling design.” Dale Kramer, flying his twin-Joby-motored eLazair around the ultralight circuit in 2011, showed the potential for electric motors on an amphibian. Sonex Aircraft showed its Waiex in its e-Flight Initiative area in the Innovation Pavilion, looking essentially the same as over past years. the company has noted several test flights since its late December, …

Electric Waiex Makes First Hop

On Friday, December 3, Sonex Aircraft, LLC achieved a long-sought goal at Wittman Field, Oshkosh, Wisconsin, successfully flying their electric two-seater Waiex.  Unveiling their craft at the 2007 AirVenture on the same field as part of their E-Flight Initiative, the team quietly and with some back-to-the-drawing-board resolve worked for the next three years to solve the many problems that confront any group reaching for that elusive next best thing.  Evidence of this are the version numbers on the motor and controller as noted in Sonex CEO and General Manager Jeremy Monnet’s comment.  “We have also already started our motor v4.0 design and motor controller v12.0 to be integrated on N270DC. Many more great things to come on this project!” Having seen Peter Buck’s video of early testing at the Experimental Soaring Association’s fall workshop in 2008, in which the controller self-immolated (later found to be the classic loose wire scenario) this writer was impressed with the openness of the presentation and the reminder that such developments are never as …
