About the Aero-Kros KR-030 Topaz

The Aero-Kros KR-030 Topaz is a Czech-built single-engine composite aircraft that straddles the line between ultralight and light-sport categories, designed for European VLA (Very Light Aircraft) certification. Introduced in the early 2000s by the Kunovice-based manufacturer, the Topaz features a distinctive high-wing configuration with a bubble canopy and fixed tricycle gear, optimized for training and recreational flying across Central Europe. Its composite construction keeps empty weight around 650 pounds while accommodating two occupants and a modest fuel load, making it economical to operate on European airfields where landing fees are weight-based.

Powered by a Rotax 912-series engine producing 80-100 horsepower, the Topaz cruises comfortably at 110-120 knots with a range of approximately 500 nautical miles, respectable for an aircraft in this class. The type's relatively low stall speeds and docile handling characteristics have made it popular with flight schools in Slovakia, Poland, and the Czech Republic, though it remains rare outside Central Europe. Its VNE of 162 knots and maximum structural cruising speed of 135 knots place it squarely in the performance envelope of modern LSA designs, offering a balance between efficiency and cross-country capability.
