Stearman C3 - American Civil multipurpose biplane, designed and produced by the company «Stearman Aircraft» with 1928 years.

Development of American biplane began aircraft manufacturers of the company «Stearman Aircraft» in 1925 year, at the same time the plane had not only become a very modern aircraft suitable for both private and for commercial exploitation, which subsequently made the aircraft very popular among owners.

aircraft design does not differ from the biplanes of the era, the only unique feature is the only thing that the passenger seats in the aircraft placed in the front part, while the pilot had to control the plane being located at the rear of the aircraft, however, this feature is almost hampered aircraft management as before the pilot had a good overview space, which was very thought out by aviarazrabotchikov.

For the first time in the air plane model Stearman C3 rose in 1927 year, however, the original model was not able to meet all the requirements, which is why the aircraft was still at its completion, and only in the year 1928, the aircraft was formally presented for several months.

Despite the fact that the release of the aircraft Stearnam C3 was conducted from the end of 20-ies of the last century, the plane is highly reliable and has a quite acceptable, even by today's standards, flight performance, in particular, high-speed flight and good maneuverability, and only perhaps vulnerable feature of the aircraft were the wings, which were not always able to withstand high overload, but later the situation was corrected.

The aircraft Stearman C3 cabin can accommodate up to three people - a pilot and two passengers, at the same time, two passenger seats positioned in front of the airplane, and the pilot's seat is in the rear of the aircraft. This arrangement will minimize the size of the aircraft, and to improve the aerodynamic shape of the aircraft, which in turn is very beneficial effect on the maneuverability of the aircraft.

Depending on its modification, the aircraft Stearman C3 can be equipped with radial piston motors from 90 hp to 260 hp, which accordingly affects the maximum speed of the aircraft, which can reach up to 210 km \ h. Quite acceptable indicator of the aircraft Stearman C3 is also the maximum flight range, which, depending on the version and the version can be up to 1005 kilometers.
