Ekolot KR-030 Topaz explained

The Ekolot KR-030 Topaz is a Polish ultralight aircraft, designed and produced by Ekolot of Krosno. It was certified in Poland in February 2010. The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly aircraft.^{[1] [2]}

Design and development

The Topaz is a development of the Ekolot JK-05L Junior and was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever high wing in place of the Junior's strut-braced wing, a two-seats-in-side-by-side configuration enclosed cockpit, fixed tricycle landing gear and a single engine in tractor configuration.^[2]

Like the Junior, the Topaz is made from composites. Its 10.761NaN1 span wing employs an NN-1817 airfoil, has an area of 10.24m2 and flaps. Dual fuel tanks are located behind the seats. A ballistic parachute is an available option. The standard engine available is the 800NaN0 Rotax 912UL four-stroke powerplant.^{[2] [3]}

The use of a one-piece wing without struts gives the Topaz a 201NaN1 higher cruise speed than the Junior, while resulting in the same empty weight.^[2]

The Topaz has been accepted by the US Federal Aviation Administration as a light-sport aircraft.^[4]
