The first flight of the Sigma-7 aircraft took place on October 7, 2020. A complex of ground tests was carried out before the flight at the TsAGI Technopark - strength tests of the wing, tail, landing gear. The flight was performed by a test pilot of the II class of LII Gromova Plaksin Denis Vladimirovich. The flight lasted 15 minutes and was carried out according to the certification test program approved by the Federal Air Transport Agency.

Light two-seat aircraft «Sigma-7» is designed in accordance with European requirements for light sport aircraft.

A specific feature of the aircraft is a "helicopter" view from the cockpit and compact folding of the wing on the sides of the fuselage.

Transportation of the aircraft on a trailer, towing behind a car on a towbar, independent movement on propeller power allow the aircraft to be based near the house, and powerful wing mechanization provides the possibility of off-aerodrome operation of the aircraft from small areas.

The aircraft can be equipped with a ski or amphibious float landing gear.
