Aircraft overview

The Ekolot KR-030 Topaz is a Polish two-seat ultralight and light sport type produced by Ekolot, a manufacturer known for composite sport aircraft. Introduced in the early 2000s, it is a high-wing, strut-braced aircraft intended for private touring, flight training and economical recreational flying. The KR-030 Topaz matters in the used market because it combines a conventional cockpit layout and predictable handling with a modern composite airframe, placing it among European microlights that can serve as practical cross-country aircraft rather than purely local flyers.

Performance & specifications

Typical KR-030 Topaz examples are powered by the Rotax 912 series, most commonly the 80 hp Rotax 912 UL or 100 hp Rotax 912 ULS, driving a fixed-pitch or ground-adjustable propeller. Published figures vary by national certification, equipment and weight category, but representative performance includes a cruise speed around 95 to 100 knots, range in the region of 500 nautical miles with reserve and a service ceiling of about 13,000 feet. Maximum takeoff weight is commonly listed in the 450 kg to 472.5 kg ultralight class, so useful load should be checked carefully against installed options, fuel capacity and local operating rules.

Cabin & avionics

The KR-030 Topaz seats two side by side under a high wing, with good downward and lateral visibility compared with many low-wing sport aircraft. The cabin is simple and compact, with baggage capacity suited to light touring rather than heavy travel loads. Avionics are aircraft-specific, since the type was not normally delivered with integrated suites such as Garmin Perspective or Garmin G1000. Used examples are more likely to have analog flight instruments, a basic engine monitor, VHF radio, transponder, portable or panel-mounted GPS and, on later or upgraded aircraft, a small EFIS suited to VFR operations.

Buying & value

Buyers should verify the exact regulatory category, weight limit and paperwork for the country of registration, as these points strongly affect operating flexibility and resale value. Important inspection areas include composite structure condition, landing gear attachments, control system play, canopy and door fit, fuel system condition and evidence of proper Rotax maintenance. Engine logbooks, gearbox service, carburetor synchronization and rubber component replacement history are particularly relevant. Common value drivers include the 100 hp Rotax 912 ULS, modern radio and transponder equipment, a clean composite finish, ballistic parachute installation where approved and documented factory support. In the used market, the Ekolot KR-030 Topaz generally sits as a practical European ultralight tourer, priced against types such as the Remos, Eurostar and other Rotax-powered two-seat composite aircraft.
