The Ekolot JK 01A Elf is a Polish mid-wing, single-seat motor glider, designed by Jerzy Krawczyk, produced by Ekolot of Krosno and provided as a complete ready-to-fly aircraft or as a kit for amateur construction.[1]

Design and development

The JK 01A Elf was designed by Krawczyk, based on the earlier work of American designer Alex Strojnikun. It features cantilever wings, a single-seat enclosed cockpit under a bubble canopy, fixed landing gear and a single engine in pusher configuration.[1]

The aircraft is made from composites. Its 11.12 m (36.5 ft) span wing has an area of 10.80 m2 (116.3 sq ft), flaperons and provides a glide ratio of 26:1. The standard engine used was a 20 hp (15 kW) JPX D-320 two-stroke, but this engine is no longer available and any small horizontally-opposed engine in the 20 hp (15 kW) range can be used. An engine of this power provides a takeoff run of 150 m (492.1 ft). The propeller used has a folding design to reduce drag and the fuel tank fitted has a volume of 15 litres (3.3 imp gal; 4.0 US gal). The landing gear uses dual, close-set mainwheels and a smaller nosewheel, with no wingtip wheels[1]

The company provides complete ready-to-fly aircraft and kits which offer the aircraft in various states of completion.[1]

The first flight was made on 8 July 2006. There is no evidence of production beyond 2007/8.[2]
