GreenWing International GW430
The Yuneec International E430 is a Chinese two-seat electric aircraft designed for commercial production by electric model aircraft manufacturer Yuneec International.
The E430 is a two-seat, V tailed, composite aircraft with a high-aspect ratio wing. Take-off speed is 40 mph, cruise speed is 60 mph, and max speed is 95 mph.
The company claims that the battery packs have an expected lifespan of 1500 hours and cost US$7000 each, with the aircraft carrying 3-5 battery packs, giving two to two and half hours endurance. The batteries can be recharged in 3–4 hours from a 220v outlet.
The aircraft was being developed as a kit aircraft for the US market. The development of the E430 was being funded entirely by Yuneec CEO Tian Yu.
The aircraft was first flown on 12 June 2009 from the Yuneec factory near Shanghai, China, and then shipped for further testing to Camarillo, California. On 14 July 2009 the prototype aircraft was registered in the USA as N386CX and on 18 July 2009 it was given a Certificate of Airworthiness by the Federal Aviation Administration and further test flights were carried out, totalling 22 hours. The prototype E430 was then shipped by truck to Wisconsin and displayed at EAA AirVenture Oshkosh in July 2009. It was also on display at that venue in summer of 2010.
In July 2009 the company estimated that the price for a commercially available light sport aircraft production version of the E430 would be US$89,000.
At AirVenture 2010 the company announced that it would start accepting orders for the aircraft after the show. At that date the aircraft was advertised as having an endurance of 2.25 to 2.5 hours with a useful load of 390 lb (177 kg). The E430 was named the winner of the Lindberg prize for electric aircraft at AirVenture in 2010. The Lindbergh Electric Aircraft Prize (LEAP) was awarded by Erik Lindbergh, the grandson of Charles A. Lindbergh and Anne Morrow Lindbergh. In the same year it was named Brit Insurance Design of the Year in the transport category. Deliveries were initially scheduled for late 2011, but by the end of 2012 there was no indication that more than prototypes had been completed.
Yuneec International, created GreenWing International and in June 2013 it was announced that their GW280 (eSypder) and GW430 (e430) airplanes will be produced, marketed and supported by GreenWing International, however that company went out of business in about 2014.
By December 2012 a total of two examples had been registered in the United States with the Federal Aviation Administration. The first one was the initial prototype shipped to the US, registered in the Experimental - Exhibition category on 14 July 2009, although its registration expired on 31 March 2012. The second was registered in the Experimental - Research and Development category on 26 January 2011 to Flying Tian of Monterey Park, California.
