Scale Model
A scale model is a physical model which is geometrically similar to an object (known as the prototype). Scale models are generally smaller than large prototypes such as vehicles, buildings, or people; but may be larger than small prototypes such as anatomical structures or subatomic particles. Models built to the same scale as the prototype are called mockups. Scale models are used as tools in engineering design and testing, promotion and sales, filmmaking special effects, military strategy, and hobbies such as rail transport modeling, wargaming and racing; and as toys. Model building is also pursued as a hobby for the sake of artisanship. Scale models are constructed of plastic, wood, or metal. They are usually painted with enamel, lacquer, or acrylics, and decals may be applied for lettering and fine details. They may be built from scratch, or from commercially made kits, either out of the box or modified (known as kitbashing). Model prototypes include all types of v ...

Scale (ratio)
The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. In such cases the scale is dimensionless and exact throughout the model or drawing. The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale. Thus on an architect's drawing one might read 'one centimeter to one meter', 1:100, 1/100, or . A bar scale would also normally appear on the drawing. Colon may also be substituted with a specific, slightly raised ratio symbol , ie. . General representation In general a representation may involve more than one scale at the same time. For example, a drawing showing a new road in elevation might use different horizontal and vertical scales. An elevation of a bridge might be annotated with arrows with a length propor ...

Polar Lights (models)
The Aurora Plastics Corporation was an American toy and hobby manufacturing company. It is known primarily for its production of plastic scale models of cars, airplanes, and TV and movie figures in the 1960s. Its principal competition in modeling were various other plastic modeling firms like Revell and Monogram. Established in 1950, the company was first sold in 1969, being then acquired by other firms until then-parent company Dunbee-Combex-Marx ceased operations in 1980. Since then, the Giammarino family have tried to reintroduce the Aurora brand, but their attempts never carried out. History Aurora Plastics Corporation was founded in March 1950 by engineer Joseph E. Giammarino (1916–1992) and businessman Abe Shikes (1908–1986) in Brooklyn, New York (moving to West Hempstead, Long Island in 1954), as a contract manufacturer of injection molded plastics. With the hiring in 1952 of salesman John Cuomo (1901–1971), the company began the manufacture of its own line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Original Series
''Star Trek'' is an American science fiction television series created by Gene Roddenberry that follows the adventures of the starship and its crew. It later acquired the retronym of ''Star Trek: The Original Series'' (''TOS'') to distinguish the show within the media franchise that it began. The show is set in the Milky Way galaxy, circa 2266–2269. The ship and crew are led by Captain James T. Kirk (William Shatner), First Officer and Science Officer Spock (Leonard Nimoy), and Chief Medical Officer Leonard H. "Bones" McCoy ( DeForest Kelley). Shatner's voice-over introduction during each episode's opening credits stated the starship's purpose: Space: the final frontier. These are the voyages of the starship ''Enterprise''. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before. Norway Productions and Desilu Productions produced the series from September 1966 to December 1967. Par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer-generated Imagery
Computer-generated imagery (CGI) is the use of computer graphics to create or contribute to images in art, printed media, video games, simulators, and visual effects in films, television programs, shorts, commercials, and videos. The images may be static (still images) or dynamic ( moving images), in which case CGI is also called ''computer animation''. CGI may be two-dimensional (2D), although the term "CGI" is most commonly used to refer to the 3-D computer graphics used for creating characters, scenes and special effects in films and television, which is described as "CGI animation". The first feature film to make use of CGI was the 1973 film '' Westworld''. Other early films that incorporated CGI include '' Star Wars'' (1977), ''Tron'' (1982), '' Golgo 13: The Professional'' (1983), ''The Last Starfighter'' (1984), '' Young Sherlock Holmes'' (1985) and ''Flight of the Navigator'' (1986). The first music video to use CGI was Dire Straits' award-winning " Money for No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tungsten Carbide
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering for use in industrial machinery, cutting tools, chisels, abrasives, armor-piercing shells and jewelry. Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530–700 GPa, and is double the density of steel—nearly midway between that of lead and gold. It is comparable with corundum (α-) in hardness and can be polished and finished only with abrasives of superior hardness such as cubic boron nitride and diamond powder, wheels and compounds. Naming Historically referred to as Wolfram, ''Wolf Rahm'', wolframite ore was then later carburized and cemented with a binder creating a composite now called "tungsten carbide". Tungsten is Swedish for "heavy stone". Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cub Scouting (Boy Scouts Of America)
Cub Scouting is part of the Scouting program of the Boy Scouts of America (BSA), available to boys and girls from kindergarten through fifth grade, or 5 to 10 years of age and their families. Its membership is the largest of the five main BSA divisions (Cub Scouting, Scouts BSA, Venturing, Exploring and Sea Scouting). Cub Scouting is part of the worldwide Scouting movement and aims to promote character development, citizenship training, personal fitness, and leadership. Origins As early as 1911, Ernest Thompson Seton had developed a prototype program he named ''Cub Scouts of America'' that was never implemented. James E. West felt that having BSA divisions for younger boys (those under 12; the "younger boy problem") would draw away boys from the core program, which was Scout troops focused on the 12- to 17-year-old age group; thus he opposed such a program for some time. In spite of this, unofficial programs for younger boys started around this time, under names such as ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boy Scouts Of America
The Boy Scouts of America (BSA, colloquially the Boy Scouts) is one of the largest scouting organizations and one of the largest youth organizations in the United States, with about 1.2 million youth participants. The BSA was founded in 1910, and since then, about 110 million Americans have participated in BSA programs. BSA is part of the international Scout Movement and became a founding member organization of the World Organization of the Scout Movement in 1922. The stated mission of the Boy Scouts of America is to "prepare young people to make ethical and moral choices over their lifetimes by instilling in them the values of the Scout Oath and Law." Youth are trained in responsible citizenship, character development, and self-reliance through participation in a wide range of outdoor activities, educational programs, and, at older age levels, career-oriented programs in partnership with community organizations. For younger members, the Scout method is part of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model Engine
A model engine is a small internal combustion engine typically used to power a radio-controlled aircraft, radio-controlled car, radio-controlled boat, free flight, control line aircraft, or ground-running tether car model. Because of the square–cube law, the behaviour of many engines does not always scale up or down at the same rate as the machine's size; usually at best causing a dramatic loss of power or efficiency, and at worst causing them not to work at all. Methanol and nitromethane are common fuels. Overview The fully functional, albeit small, engines vary from the most common single-cylinder two-stroke to the exotic single and multiple-cylinder four-stroke, the latter taking shape in boxer, v-twin, inline and radial form, a few Wankel engine designs are also used. Most model engines run on a blend of methanol, nitromethane, and lubricant (either castor or synthetic oil). Two-stroke model engines, most often designed since 1970 with Schnuerle porting for b ...

Radio-controlled Aircraft
A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is controlled remotely by an operator on the ground using a hand-held radio transmitter. The transmitter continuously 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, directly affect the orientation of the plane. Flying RC aircraft as a hobby grew substantially from the 2000s with improvements in the cost, weight, performance, and capabilities of motors, batteries and electronics. Scientific, government, and military organizations are also using RC aircraft for experiments, gathering weather readings, aerodynamic modeling, and testing. A wide variety of models, parts, and styles is available for the DIY market. Nowadays, distinct from recreational civilian aeromodelling activities, Unmanned aerial vehicle (drones) or spy ...
