Designed, built and flight-tested in Pravets, Bulgaria — by a family company that has been shaping metal and composite since 1994. Today, our gyroplanes are flown by dozens of owners around the world.
01The workshop
For thirty years we have shaped metal, composite and wood with obsessive precision. Then we pointed that craft at the sky. Every NIKI gyroplane is built in our own halls, flown by our own test pilot and handed over ready to fly.

Laid by hand.
The cabin is a carbon monocoque. Each shell is laid up, cured and trimmed in our own composite hall.

Finished to your order.
Paint, pinstripe, leather and stitching are chosen by the owner and applied by the people who built the aircraft.
Fig. 04 — Assembly
Assembled in one hall.
Composite shell, metal frame, finishing — produced in our own halls in Pravets, not assembled from a catalogue.
Fig. 05 — Flight test
Flown before it is yours.
Our flight test engineer breaks in every engine and flight-tests every gyroplane before delivery.
