The McCulloch MC-4 helicopter was developed by the US aircraft manufacturer as a promising aircraft for use in the US Armed Forces, in particular the Navy. The helicopter had to perform various tasks related to reconnaissance, enemy detection, search operations, etc., however, despite its shape and the presence of two rotors, the aircraft of this model could not be used as a transport airplane, since the maximum take-off The weight of the aircraft was very much limited, to a greater extent using a low-power power plant.

Despite the relatively small size of the helicopter, the aircraft has a very low maneuverability, which was due to poor aerodynamics, because the actual beginning of the era of helicopter industry, as well as the presence of a helicopter two screws that have hampered the implementation of complex maneuvers.

His first ascent into the air helicopter model McCulloch MC-4 has made in 1951 year, however, the first test of the aircraft pointed to a number of shortcomings, unaccounted for at the design stage, and therefore, before going into mass production, the helicopter has undergone a number of important design and technical changes.

Depending on the modification of the aircraft model McCulloch MC-4, on board a helicopter can accommodate from two to 4 people, including some versions of the aircraft have been optimized for the transportation of small cargoes, however, a condition that has been compliance with the size and exceeding of the maximum take-off the mass of the helicopter is about 900 kg.
