History of Radio Controlled Model Helicopters

Although experiments with rotary winged surface of the wing.The helicopter
aircraft may be traced back to Leonardo generates lift by the movement of its
da Vinci, successful flights were not main rotor blades through the air as its
achieved until the 1930s, and it was not rotor turns. The blades have to be moved
until 1941 that the first practical, full at high speed and at a comparatively high
size helicopter was built by lgor angle of attack in order to produce
Sikorsky. Model enthusiasts are notably sufficient lift to raise the model into
quick to emulate full-size aviation the air. Weight is critical and
achievements, but were not as successful experimenters who discovered that their
with rotary wing aircraft, and it was not chosen engine had insufficient power to
until 1968 that the first fully produce the required lift were faced with
controllable R/C model helicopter a vicious circle. Fitting a larger engine
appeared, built by Dr. Dieter Schluter of to increase the available power also
West Germany.Many modellers were meant an increase in the weight to be
convinced that the single rotor autogiro lifted.Bigger engines require more fuel
would be an easier subject to tackle than and more weight! Increasing the angle of
the helicopter and were conducting their the rotor blades in the airflow produces
experiments along these lines, but in more lift, up to a point but this also
fact the first really successful British increases the drag of the blade, which
R/C autogiro, a semi-scale model of the now requires more power to move it at the
Wallace Autogiro, was first flown in required speed. All problems were

appearance of the R/C helicopter. controllable R/C model helicopter had
Designers and manufacturers the world arrived.There were, however, no short

Schluter's success and, In the early gears, rotor blades, control methods, etc
1970s, model helicopter kits were on sale all had to follow a similar design to
in the model shops.In order to appreciate full-size helicopter and be built to the
the reasons for the slow development of same exacting standards or perhaps closer
the model helicopter, at least a few of to the mechanism design of the full-size
the problems which faced the pioneers helicopter.So how difficult is the model
must be considered. These problems were helicopter to control in fight? Well, it
many and complex, for instance in order has been described as similar to
