Jane Zhanf of Silk Wings Aviation (see note), an aircraft consulting firm, commented on an earlier post about the RX1E, an airplane designed by Shenyang University students and demonstrated at two airshows over the last two years.  Similar to the Yuneec (GreenWings) E430, it is a totally different design. “CAAC (Civil Aviation Administration of China) just awarded[a]TDA (Type Design Approval) to them! “By the way, Yuneec E430 is not widely known in China, not an excuse for the wrong claim of being #1 from China though.  (Editor’s Note: The E430 is being developed by GreenWings, now based in California.  It uses a Yuneec motor.) “Given FAA and EASA don’t support electric SLSA (Special Light Sport Aircraft – allowed to be used …

Shanghai-based Yuneec, already promoting a line of electric paramotors, an electric trike, the two-seat E430, unveiled at last year’s AirVenture, and a series of motor/controller/battery combinations, has added to their offerings at AirVenture 2010.  New craft include two aircraft, the Apis 2 and Viva from Martin Wezel Flugzeugtechnik, a German designer and purveyor of sailplanes and light sport aircraft.   The Apis 2 is a derivation of the Silent electric sailplane, and in this application will be powered by a Yuneec motor system.  The Viva, a two-seat motorglider, was designed originally for an HKS-700E two-cylinder engine of about 60 horsepower, and will be converted, like the Apis, to Yuneec power. Spanning 15 meters (49.2 feet), the Apis 2 has a best lift-to-drag …

 Last year, we knew Yuneec for its tidy power package for paramotors, the 10 kW EPac.  We were awaiting developments on the EP200, a twin-motored, single-place ultralight that looked as though it would be powered by two EPac units.  Springtime, 2009 brought the news that a two-seater was under development, and summer brought surprise after surprise.  The 40 kW (54 horsepower) E430 made its first flights on June 12, 2009, followed by further testing on June 20.  Test pilot Sun Xun managed two flights of 15 minutes, achieving a top speed of 150 kilometers per hour (93 mph) a climb rate of 7 meters per second (1,377 feet per minute), and a maximum altitude of 300 meters (960 feet).  Sun …
