As of 2026, the PV-10 Tango is under development, with certification expected to be carried out later in the year, and serial production expected by 2027.
Development
In an interview with the newspaper Izvestia, S7 Group founder Vladislav Filev announced the creation of a four-seater composite aircraft, as well as accompanying piston engine.
During the Innoprom-2025 exhibition in July 2025, Spectra Aircraft CEO Alexander Stepanov announced that operational tests were planned to be complete by the end of the year, with certification beginning in 2026.
APD-520 Lider
On 24 December 2025 an updated prototype took flight, where performance and flight characteristics were checked. As a result of design optimisation, this aircraft had improved aerodynamic performance. It was further noted that testing of the APD-520 "Lider" engine was underway.
On 14 July 2026, the first flight of a Tango equipped with a domestically produced APD-520 engine took place, once again piloted by test pilot Vladimir Barsuk.
On 31 August 2026, a third prototype Tango made its first flight. The aircraft was equipped with an APD-520 engine, but differed from the previous aircraft by mounting a variable-pitch propeller.
