A radio-controlled helicopter (also RC helicopter) is model aircraft which is distinct from a RC airplane because of the differences in construction, aerodynamics, and flight training. Several basic designs of RC helicopters exist, of which some (such as those with collective pitch control) are more maneuverable than others.
The prototype of the one-man open framework homebuilt helicopter powered by a 34 hp (25 kW) Triumph motorcycle engine. Hobbycopter 101 Production version of the XH-1 offered as a kit for $900, or as plans for $35 to homebuilders. Hobbycopter 102 Strengthened Model 101 with 34 hp (25 kW) Triumph and a fibre-glass cockpit enclosure.
Model aircraft are divided into two basic groups: flying and non-flying. Non-flying models are also termed static, display, or shelf models. Aircraft manufacturers and researchers make wind tunnel models for testing aerodynamic properties, for basic research, or for the development of new designs. Sometimes only part of the aircraft is modelled.
The subsequent Model 30 helicopter of 1943 showed the design's simplicity and ease of use. The Model 30 was developed into the Bell 47 of 1945, which became the first helicopter certified for civilian use in the United States (March 1946). Produced in several countries, the Bell 47 was the most popular helicopter model for nearly 30 years.
Non-RC. Engine powered a small rotor which lifted the model up; a larger free-wheeling rotor auto-rotated the model down when the fuel ran out. Location of touchdown at the mercy of prevailing winds. Different fuselage kits by German RC helicopters manufacturer Vario [22] with optional functional retractable machine guns (firing blanks).
