Kyosho

Kyosho is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kyosho rather than just read about it. In short: Kyosho Corporation (京商株式会社, Kyōshō Kabushiki Kaisha) is a Japanese company based in Tokyo, which operates internationally under the name KYOSHO. The company's main office is located in Chiyoda, and the production headquarters are located in Atsugi, Kanagawa.

Key takeaways

Kyosho belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kyosho to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kyosho from memory before moving on to harder problems.

Reference excerpt

Kyosho Corporation (京商株式会社, Kyōshō Kabushiki Kaisha) is a Japanese company based in Tokyo, which operates internationally under the name KYOSHO. The company's main office is located in Chiyoda, and the production headquarters are located in Atsugi, Kanagawa. Established in October 1963, Kyosho created its first trademark radio-controlled model car in 1970, being one of the oldest RC makers in Japan, and producing a variety of products, including cars, airplanes, helicopters, and boats. Kyosho also produces die-cast model cars, which production started in 1992. Its major competitor in the RC automobile market is Tamiya. Kyosho has avoided direct competition against Tamiya in the hobby grade RC cars market since the 80s and 90s, where Tamiya was most active, focusing instead on designing professional 1/8 scale racing buggies, Mini-Z series, and RC helicopters. The company is best known for the Inferno, its 1:8 scale competition buggies; Mini-Z series, and RC helicopters, but it also produces remote-controlled bipedal robots in the Manoi series.

R/C Products

Kyosho produces a wider range of RC products than any other RC manufacturer, including racing and ready-to-run cars, trucks, excavators, helicopters, scale, sport and warbird RC planes, and a range of RC boats. Having recently acquired Team Orion, Kyosho now has category-leading products in electric motors (brushed and brushless), Ni-MH and Li-PO batteries and battery chargers. Notable Products

Electric off-road cars During the 1980s, the 1/10 scale electric off-road car (buggy) was immensely popular, leading to the release of several different models. Many of these models have retained popularity, even after going out of production.

DASH 1 Kyosho started selling the DASH 1 in 1970, accepted widely in the industry as the first RC car made in Japan. There were three body styles to be chosen from; the most popular racing machines in the Japanese Grand Prix: the Porsche 917, Lola T70 and McLaren Elva. The bodies were vacuum molded, a totally new innovation in RC cars at the time. The DASH 1 was priced at 23,000 yen, not including the engine. Engines used were still the imported 19-class VECO (West Germany) and K&B (U.S.A.) marine engines with a Perry Carburettor and Kyosho's Fuel Stopper and a car muffler.

DASH 2 In 1971 the DASH 2 targeted at beginners (price: 16,500 Yen) was released. The DASH 1 used a two-piece chassis, but the DASH 2 had a one-piece chassis and the engine was only at a slight front angle. In addition, the SUPER DASH (price: 26,000 Yen) was released as a competition level machine.

DASH 3 The DASH 3 and the DUNE BUGGY were released in 1972, starting the buggy racing phenomenon.

Eleck Peanuts This was the first electric off-road car sold by Kyosho. A motor was placed on the PeanutBuggy, which had previously been sold as an engine car. It was sold for 9,800 yen at the time.

Rally-sports A 2WD off-road car with a RS540 motor in the rear. The frame was that of the Alpine A310. Uses a double wishbone for front suspension, and a semi-streaming arm for rear suspension. The cars aluminum frame and rear design were passed on to the Scorpion. Sold for 16,000 yen at the time.

Worked examples

Example 1 — a first encounter with Kyosho

Start with the simplest possible case. Write down what Kyosho claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kyosho before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kyosho ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kyosho

In research: Kyosho appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kyosho in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kyosho is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1963 establishments in Japan, Kyosho, Manufacturing companies based in Tokyo, so understanding it makes those chapters shorter.
In everyday life: Look for Kyosho outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
