Sonex Moves Closer to Electric Flight

More electric-powered aircraft are taking wing as battery, motor and controller technology make e-flight possible. Now American homebuilt aircraft manufacturer Sonex is about to join the party as it moves another step closer towards the dream of electric flight.

Revealed for the first time at the 2007 EAA AirVenture fly-in at Oshkosh, Wisconsin, the company continues to make steady progress on their power plant, recently beginning load tests on their electric motor. They report on their web site that their battery pack is slated to be delivered this Spring.

AvWeb visited the Sonex facility and recorded the following demonstration of the company's e-Flight Initiative by company founder John Monnet.

According to the company's AeroConversions web site, the electric Waiev will have an initial top speed of 130 mph. Depending on its flight profile, its endurance will range from 25-45 minutes, "or longer."

More details of on the electric power plant are available on the company web site, including March 17, 2008 video of the first test runs of the 50lbs., 3 phase, 270 volt, 200 amp motor.
