The first hovering flight was performed by the Russian modernized Mi-34M1 helicopter, equipped with a VK-650V turboshaft engine manufactured by UEC-Klimov. The Mi-34M1 helicopter is a modernized version of the light helicopter of the Mi-34S family, equipped with piston engines. Serial production of the VK-650V engine, designed for Russian multi-purpose and special helicopters with a takeoff weight of up to 4 tons, is planned to be launched in 2025. A new gearbox was also tested on the helicopter. It is believed that the helicopter will compete with the most popular family of GA helicopters in the world, Robinson.
