Light multipurpose military helicopter model Bell ARH-70 Arapaho began to be developed in the US aviation specialists 2004 year. To minimize the cost of the project, aircraft manufacturers of the company «Bell Helicopter» persuaded the American military command to use as a base the design of the helicopter model Bell 407, which very successfully established itself in the commercial sphere of its use. Less than 2,5 years of work, American designers are not only able to develop a multipurpose aircraft, but also to have time to produce its initial tests, which however did not lead to the beginning of serial production of the helicopter due to a number of problems discovered during testing.

The main problem of the helicopter model Bell ARH-70 Arapaho was his poor handling, and if in terms of maneuverability of the aircraft did not cause any complaints, then landing on a limited area, the pilot had to have high skills of professionalism, which in fact, is not allowed to use this model in the US regular army, in this connection, the designers of the company «Bell Helicopter» was proposed to improve the model and refine it.

Later, the American aircraft manufacturers have been created three more prototype helicopter Bell ARH-70 Arapaho, but none of them did not have the required aircraft performance parameters, as a consequence. The project was decided to close, however, at the end of the year 2014 appeared anecdotal evidence that the development of the military helicopter Bell ARH-70 Arapaho again continued, however, either by the «Bell Helicopter» manual? either by the American military command, this information is official confirmation was not found.
