S7 Group intends to conduct tests of the APD-520 "Leader" aviation piston engine of its own design in the summer of 2025. The amount of investment has not been disclosed at this time.
In the first year, S7 plans to produce at least 30 engines, which will be used to equip four-seater Tango light aircraft. Production of the aircraft themselves is scheduled for the end of 2026 – beginning of 2027.
The APD-520 engine was developed by the S7 Group design bureau based on the classic design of a six-cylinder internal combustion engine with air cooling. Power is 200 hp, time between overhauls is 1500 hours with the potential to increase to 2000, and working volume is 5.2 liters.
The Tango aircraft is being developed as a training aircraft, designed for the training of civilian pilots. The take-off weight is 1200 kg, and the aircraft can reach speeds of up to 241 km/h with a maximum flight range of up to 1100 km.
According to an S7 representative, government agencies and flight schools are interested in the aircraft, especially in regions with difficult transport accessibility.
