In 1966, MVZ built a full-scale mockup of the aircraft with a 355 hp Turbomeca "Oredon-III" single-turboshaft engine and tricycle-type landing gear. Later, in 1972, MVZ built another mockup, but with a TBG-11 hp engine type and a skid undercarriage. The helicopter did not attract many customers after the second mock-up and did not replace the Mil Mi-1. Because of this, further development of the aircraft was canceled.
