KO PROPO is a brand of radio control equipment and humanoid robot (KHR-1) by Kondo Kagaku, established in Tokyo, Japan in 1945.
In 1982 KO PROPO introduced the Expert EX-1, reported to have been the first to integrate a pistol grip into a transmitter device with a gun trigger to act as the throttle, which later became a popular fixture in radio controlled transmitters.
As of 2016 [update] the company had won 32 IFMAR World titles.
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In amplitude modulation, the amplitude of the carrier wave is varied in proportion to that of the message signal being transmitted. The message signal is, for example, a function of the sound to be reproduced by a loudspeaker, or the light intensity of pixels of a television screen. This technique contrasts with frequency modulation, in which the frequency of the carrier signal is varied, and phase modulation, in which its phase is varied.
Radio-controlled cars are miniature model cars or trucks that can be controlled from a distance using a specialized transmitter or remote. The term "RC" has been used to mean both "remote controlled" and "radio controlled", where "remote controlled" includes vehicles that are controlled by radio, infrared or a physical wire connection. Common use of "RC" today usually refers only to vehicles controlled by radio, and this article focuses on radio-controlled vehicles only.
A radio-controlled model is a model that is steerable with the use of radio control. All types of model vehicles have had RC systems installed in them, including cars, boats, planes, and even helicopters and scale railway locomotives.
In electronics, a remote control or clicker is an electronic device used to operate another device from a distance, usually wirelessly. For example, in consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other home appliance, from a short distance. A remote control is primarily a convenience feature for the user, and can allow operation of devices that are out of convenient reach for direct operation of controls. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside or when a Digital Light Processing projector that is mounted on a high ceiling is controlled by a person from the floor level.
Radio control 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 for both civilian and military uses, although these have more sophisticated control systems than traditional applications.
Japan Remote Control Co., Ltd. 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.
A radio-controlled aircraft is a small flying machine that is controlled remotely by an operator on the ground using a hand-held radio transmitter. The transmitter communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on the position of joysticks on the transmitter. The control surfaces, in turn, affect the orientation of the plane.
A radio-controlled 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 are more maneuverable than others. The more maneuverable designs are often harder to fly, but benefit from greater aerobatic capabilities.
Buddy box or buddy boxing is a colloquialism referring to two R/C aircraft radio systems joined together for pilot training purposes.
Masami Hirosaka is a Japanese radio controlled car driver who is considered to be the world's most successful with a record fourteen IFMAR World Championships in 1/12 scale electric, 1/10 scale Pan, 1/10 scale 2WD off road and 1/10 scale 4WD, all electric. Hirosaka's peers have nicknamed him "Master Masami". He was considered to be one of the highest paid drivers in RC racing, until he retired from the activity. His last IFMAR race was the 2008 world championship in Thailand. His retirement ceremony was on May 3, 2009.
Multiplex Modellsport GmbH & Co. KG of Bretten-Gölshausen, Germany is a manufacturer of hobby-grade radio control electronics, electric radio-controlled airplanes and electric helicopters.
WPHM is a News/Talk/Sports radio station licensed to Port Huron, Michigan at 1380 kHz on the AM dial, with a power output of 5,000 watts. The station is owned by Radio First. WPHM is an affiliate of ABC Radio, Bloomberg Radio, SB Nation Radio, Brownfield Ag News, and the Michigan News Network.
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.
WVTF is the National Public Radio affiliate serving most of southwestern Virginia. The station is licensed to Roanoke, Virginia, and owned by Virginia Polytechnic Institute and State University through its fundraising arm, the Virginia Tech Foundation. It airs a format of news and talk programming from NPR, BBC World Service, Public Radio International and other outlets.
KFTK was a commercial radio station that was licensed to East St. Louis, Illinois at 1490 AM, and broadcast from 1972 to 2020. KFTK's transmitter was located in East St. Louis. From 2016 to 2020, KFTK and low-power translator K254CR were operated by both Emmis Communications and Entercom as a full-time simulcast of KFTK-FM (97.1).
The AN/MRN-1 was an instrument approach localizer used by the Army Air Force during and after World War II. It was standardized on 3 July 1942. It replaced the SCR-241, and was a component of SCS-51.
Servos are small, cheap, mass-produced servomotors or other actuators used for radio control and small-scale robotics.
The IFMAR World Championship for 1:10th Electric Off-Road Cars, is a world championship radio controlled car race hosted by the International Federation of Model Auto Racing (IFMAR). It takes place biennially on odd years since 1987 in its current format but inaugurated in 1985 as a championship for Stock and Modified class It is considered by the radio-controlled modelling industry to be the most prestigious event in the calendar that a number of mainstream hobby and toy brands have fielded factory entries.
Sanwa Electronic Instrument Co., Ltd., widely known as Sanwa, is a brand of wireless equipment best known for its high end radio-controlled transmitters 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-controlled transmitters in 1974 and remote control devices for home and industrial use since 1985.
Clifton Bradley Lett is an American retired radio-controlled racer and the current president of Associated Electrics, where he began his R/C career in 1985. A former motorcross mechanic for Yamaha, he won seven ROAR National Championships, three NORRCA National Championships and the 1991 IFMAR World Championship and was one of the foremost drivers of the 1980s. Lett, known as "the Buggymaster", helped refine the Associated RC10 and other models in the range. He was the first driver to exceed 100 miles per hour (160 km/h) with a radio-controlled car, recorded by Guinness World Records at 111 miles per hour (179 km/h) in 2001.
