1:10 scale radio-controlled car. ( Saab Sonett II) A radio-controlled model (or RC model) is a model that is steerable with the use of radio control (RC). All types of model vehicles have had RC systems installed in them, including ground vehicles, boats, planes, helicopters and even submarines and scale railway locomotives.
Radio control (often abbreviated to RC) is the use of control signals transmitted by radio to remotely operate a device. Examples of simple radio control systems are garage door openers and keyless entry systems for vehicles, in which a small handheld radio transmitter unlocks or opens doors. Radio control is also used for control of model ...
Radio-controlled boat. A mass-produced radio-controlled yacht. In 1898, Tesla demonstrated a radio-controlled boat ( U.S. patent 613,809 — Method of an Apparatus for Controlling Mechanism of Moving Vehicle or Vehicles ). A radio-controlled boat is a boat or ship model controlled remotely with radio control equipment.
The servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.
Graupner/SJ GmbH is a radio control equipment manufacturing company founded in 1930 by Johannes Graupner in Stuttgart-Wangen. Taken over in 1953 by son Hans, the company became the leading designer and producer of aircraft and boat radio-controlled models. Providing the world RC market with RC radios and on board sensor equipment, it was ...
One common application with these channel characteristics, first used in the early 1960s with top-end HF (as low as 27 MHz) frequencies into the low-end VHF band frequencies (30 MHz to 75 MHz for RC use depending on location), is the radio control of model aircraft, boats and cars, originally known as "digital proportional" radio control. PPM ...
Mechanical or "wind vane" self-steering started out as a way to keep model sail boats on course. Before the advent of radio control, model yacht racing (started before WW1) was typically contested on long narrow ponds, and the number of stops along the banks was counted as a penalty in the final result. Initially a system of counterweight on ...
Kraft Systems, Inc., was an American electronics company based in San Diego County, California, and active from 1962 to 1994. The company was founded by Philip O. Kraft and began as a manufacturer of transmitters for radio-controlled models, namely RC aircraft. In 1972, the company was acquired by the Carlisle Corporation of Cincinnati, Ohio ...
