Designing a model helicopter Kaman K-1125 started by American aircraft manufacturers of the company «Kaman Aircraft» in 1959 year. A certain success of the aircraft model Kaman HH-43 Huskie, has led to the popular belief aircraft manufacturers manuals that on the basis of a military aircraft, is required to develop a civilian model helicopter that can perform a carriage on its occupants and cargo transportation.

Draft helicopter Kaman K-1125 was developed in just one year, and in the year 1960, aeronautical engineer embarked on the immediate creation of the first prototype, which was held very successfully tested in 1962, the first rising into the air. However, in actual mass production of the aircraft Kaman K-1125 it was not sent, and the main reason for this was the absence of direct orders from buyers, who believed that the helicopter has no prospects for its further use.

To the greatest extent, the purchase of helicopters models Kaman K-1125 interested in American military commanders, who believe that the aircraft can be used for the transport of troops on its board and to transport loads up to 2 tons. However, the final contract for the supply of transport helicopters in the armed forces of the United States was signed with another American aircraft manufacturer, and therefore, the release of the model Kaman K-1125 did not take place.

The Kaman K-1125 helicopter received a more modernized fuselage and became more maneuverable due to improved aerodynamic performance. On board the Kaman K-1125 aircraft can accommodate from 8 to 14 people, including two crew members, which depends mainly on the layout of the cabin, which would allow the helicopter to be used in its commercial operation, however, due to the above reasons, this And did not happen. Due to the large amount of free space on board the helicopter, the aircraft can also carry cargoes with a total mass of up to 2050 kilogram, while the presence of the rear door provided unimpeded loading of even large objects.
