The Mil Mi-30 is a passenger transport convertiplane-type rotorcraft project that started in 1972 and was called the Vintoplan. It was built to replace the Mi-8/Mi-17 helicopters and carry 19 passengers or 2T of cargo. It was expected to use a twin TV3-117 turboshaft engine and a four-bladed propeller rotor on each wing. In 1991, EDO projected three versions of the aircraft: Mi-30S, Mi-30D, and Mi-30L. The only flyable version ever built was a small-scale RC version for testing its flight capabilities.
