Ekolot KR-030 Topaz

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.
Like the Junior, the Topaz is made from composites. Its span wing employs an NN-1817 airfoil, has an area of and flaps. Dual fuel tanks are located behind the seats. A ballistic parachute is an available option. The standard engine available is the Rotax 912UL four-stroke powerplant.
The use of a one-piece wing without struts gives the Topaz a higher cruise speed than the Junior, while resulting in the same empty weight.
The Topaz has been accepted by the US Federal Aviation Administration as a light-sport aircraft.
