The VL-3 Evolution also called the Aveko VL-3 Sprint is a Czech ultralight aircraft, designed and initially produced by Aveko of Brno. The design is now produced by JMB Aircraft of Choceň. The aircraft was originally supplied by Aveko complete ready-to-fly, but is now owner-completed through a factory assistance program.[2][3][4][5]
Design and development
[edit]The aircraft was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing a two-seats-in-side-by-side configuration enclosed cockpit, fixed or retractable tricycle landing gear and a single engine in tractor configuration.[2][3]
The aircraft is made from composites. Its 8.44 m (27.7 ft) span wing has a small wing area of 9.77 m2 (105.2 sq ft). The standard engine is the 100 hp (75 kW) Rotax 912ULS four-stroke powerplant.[2][3]
A fixed gear version with a larger wing span and area as well as a higher gross weight was developed for the US light-sport aircraft category and was marketed from about 2009 to 2016 by Gobosh Aviation as the Gobosh 800XP.[2][3] By 2016 the Gobosh Aviation company website had been taken down and the company had likely gone out of business.[6]
