Yuneec E-430 / 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.

Yuneec eSpyder / GreenWing International GW280
The Flightstar is a large family of single and two-seat, high wing, single engined kit aircraft that was produced by Flightstar Sportplanes of South Woodstock, Connecticut. In 2009 the rights, tooling and parts inventory were sold to Yuneec International of China when Flightstar Sportplanes’ business was wound up.
In April 2014 Yuneec International of China debuted its eSpyder electric at the AERO event in Germany. The eSpyder is a reworked Flightstar ultralight from the 1980s. Flight Design USA’s Tom Peghiny, producer of the Flightstar for many years, sold the design to Yuneec but continued helping with development. The eSpyder, has completed Germany’s DULV aviation standard.
In July 2009 a new single seat model was exhibited at EAA AirVenture Oshkosh. The aircraft is intended to be developed into a commercially available kit and forecast to be available for under US$25,000.
The e-Spyder is an electric-powered and beefing up (enlarging and strengthening) version of the Flightstar Spyder. The aircraft replaces the Spyder’s two-stroke engine with a Yuneec Power Drive 20 20 kW / 27 hp electric motor and two 28 lb (13 kg) Lithium polymer battery packs which provide a 40-minute endurance.
The E-Spyder, a single seat electric powered aircraft featuring the PowerDrive 24 propulsion system integrating the Motor, Motor Controller, 75 Volt Battery, and Charger, received the world’s first type certification for an electric aircraft from Deutschen Ultraleichtflugverbandes (DULV) E.V in 2013.
Yuneec International created GreenWing International to further develop and market their GW280 (eSypder) and GW430 (e430) airplanes. GreenWing International went out of business in about 2014.
GreenWing International had announced the release of its first 50 eSpyder single-seat electric planes, which were to be sold as build-it-yourself kits for for under US$40,000.

YumashievYu-1
AB Yumashiev built the Yu-1 glider in Kiev in 1925. Designed as a training glider, it was developed with a view to participating in the competitions that year in Crimea.
The Yumashiev Yu-1 (Russian: Юмашев Ю-1) was conceived as a single-seat training glider. It was conceived as a high-wing cantilever monoplane. The wing, with the Pr-426 profile, had a double spar structure and a trapezoidal shape in the plane.
The fuselage was built with a plywood frame structure and had an aerodynamic wing profile shape (curved at the top and flat at the bottom). The front 2/3s were covered in sheets of plywood. The tail section was covered with fabric.
The Yu-1’s offset rudders featured a rounded shape.
The landing gear featured a conventional wheeled structure, but for record flights they could be concealed within the fuselage. For training flights they were kept exposed.
First flying in September 1925, the Yu-1 glider was entered in the III National Sailing Competitions held in Koktebel in 1925. On September 30, Yumashiev managed to stay in the air in this glider for 1 hour and 30 minutes, which was a national record.
A day later, on October 1, Yumashiev at the controls of the Yu-1 would achieve for the first time in the USSR, a long-distance flight taking advantage of thermal currents. This flight recorded 4800 meters and was considered a national record, because in the competitions the longest flight value would be 24.4 km, reached by the German Nering on his “Consul” glider. For this flight Yumashiev would receive the award for second place in the competition.
