The aircraft is now equipped with the APD-520 Lider engine developed by S7 Group. Before its first flight, the engine underwent a series of ground tests to verify its reliability, the accuracy of its operating parameters, and other characteristics.
At the same time, the Spectra PV-10 Tango demonstration aircraft made its first flight two years ago. At the time, the aircraft was powered by a 200-horsepower, six-cylinder ULPower 520iS engine developed by Belgian company ULPower. However, plans were already underway to replace it with a domestically developed engine, which was undergoing testing at the time.
According to russian sources, the engine is essentially a copy of the Belgian model, developed through reverse engineering and featuring identical specifications.
The Spectra PV-10 Tango is a four-seat training aircraft designed for the initial training of civil and general aviation pilots, as well as private flying. It is not intended for military use.
This aircraft has a maximum takeoff weight of 1,150 kg and a range of 1,100 km. It is 8.2 m long and has a wingspan of 12 m. It can reach a speed of 245 km/h.
