Japan Radio
Japan Remote Control Co., Ltd. (日本遠隔制御株式会社; ''Nippon Enkaku Seigyo Kabushiki Gaisha'') (commonly called source Propo, source Racing, or hum) was a Japanese manufacturer of popular radio control devices including transmitters, receivers, servos, electronics, programmable robots and model aircraft. JR has ceased production of RC equipment. Overview Unique to JR Propo's radios is the company's patented ABC&W technology, or Automatic Blocking Circuit with Window. Simply put, this system rapidly reroutes incoming signals through a series of ever-smaller electronic "windows," effectively blocking out spurious signals which cause radio "glitching". Any signal that does get through the system is filtered before being sent to the servos all without noticeable lag or delay. If the signal is unable to be processed, it is rejected, again without noticeable reaction. Competing brands of radio control systems include, Spektrum RC, Sanwa, Futaba, Hitec, KO Propo, Je ...

Radio Control
Radio control (often abbreviated to RC) is the use of control signals transmitted by radio to remotely control 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 vehicles from a hand-held radio transmitter. Industrial, military, and scientific research organizations make use of radio-controlled vehicles as well. A rapidly growing application is control of unmanned aerial vehicles (UAVs or drones) for both civilian and military uses, although these have more sophisticated control systems than traditional applications. History The idea of controlling unmanned vehicles (for the most part in an attempt to improve the accuracy of torpedoes for military purposes) predates the invention of radio. The latter half of the 1800s saw development of many such devices, connected to an operator by wires, inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna (radio), antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for Communication engineering, communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heatin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receiver (radio)
In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves of radio frequency) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation. Radio receivers are essential components of all systems that use radio. The information produced by the receiver may be in the form of sound, video (television), or digital data. A radio receiver may be a separate piece of electronic equipment, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servomechanism
In control engineering a servomechanism, usually shortened to servo, is an automatic device that uses error-sensing negative feedback to correct the action of a mechanism. On displacement-controlled applications, it usually includes a built-in encoder or other position feedback mechanism to ensure the output is achieving the desired effect. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position, speed, attitude or any other measurable variables. For example, an automotive power window control is not a servomechanism, as there is no automatic feedback that controls position—the operator does this by observation. By contrast a car's cruise control uses closed-loop feedback, which classifies it as a servomechanism. Applications Position control A common type of servo provides ''position control''. Commonly, servos are electric, hydraulic, or pneumatic. They operate on the principle of negative feedback, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model Aircraft
A model aircraft is a small unmanned aircraft. Many are replicas of real aircraft. 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. Static models range from mass-produced toys in white metal or plastic to highly accurate and detailed models produced for museum display and requiring thousands of hours of work. Many are available in kits, typically made of injection-moulded polystyrene or resin. Flying models range from simple toy gliders made of sheets of paper, balsa, card stock or foam polystyrene to powered scale models built up from balsa, bamboo sticks, plastic, (including both moulded or sheet polystyrene, and styrofoam), metal, synthetic resin, either alone or with carbon fibr ...

Spektrum RC
Spektrum is a brand of radio control systems designed for use with hobby radio-controlled cars and aircraft. Spektrum is a division of Horizon Hobby. The R/C hobby in the United States, Japan, and Europe typically used to employ FM radio control in HF and VHF bands such as 27 MHz, 35 MHz, 49 MHz, and 72 MHz. Most manufacturers of radio gear (all non-toy manufacturers) now use the 2.4 GHz band for their transmitters and receivers. Spektrum systems are distinguished in that they use direct-sequence spread spectrum (DSSS) technology on the 2.4 GHz ISM band. Spektrum refers to their technology as "Digital Spectrum Modulation." Each transmitter has a globally unique identifier (GUID), to which receivers can be bound, ensuring that no transmitter will interfere with other nearby Spektrum DSMx systems. The Spektrum system is also one of the manufacturers which offers "Model Match" in which the receiver in a particular model can be bound to one and only one ...

Sanwa Electronic
, widely known as Sanwa, is a brand of wireless equipment best known for its high end radio-control gear for scale modelling use. The company have been a subsidiary of the SMC Group since 1965 and began to diversify into the manufacturing of radio-control equipment (transmitters and the devices which they control) in 1974 and remote control devices for home and industrial use since 1985. In North America, Sanwa transmitters were marketed as Airtronics up until early 2016, which began as an independent company producing model airplanes. History Sanwa, originally as part of Sansei Electric Industry, specialized in the research and development of remote control devices in 1959. It merged with Sanwa Denki Manufacturing in 1965 and then became part of the SMC Group. In January 1974, Sanwa entered production and sales of transmitters for radio-controlled models and in December, became a member of the Japan Radio Control Model Industrial Association (JRM). In 1975, Sanwa became a divis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
