The fuel used to power the engine is called Model Engine Fuel, a mixture of methanol (70–40%), castor oil (20%) and nitromethane (10–40%). The Cox line of reed valve engines designed prior to 1960 used a rear reed valve induction system.
Cox Models, a former division of Estes Industries of Penrose, Colorado, was a multimillion-dollar hobby company, is one of the hobby industry's oldest companies and is noted for its production of miniature model internal-combustion engines.
An old Cox Golden Bee 0.049 cubic inch (0.8 cubic cm.) reed valve engine disassembled. The weight is two and a quarter ounces with the propeller and large fuel tank, but without fuel.
Glow fuel is a fuel source used in model engines – generally the same or similar fuels can be used in model airplanes, helicopters, cars and boats. [1] Glow fuel can be burned by very simple two-stroke engines or by more complicated four-stroke engines, and these engines can provide impressive amounts of power for their very small size.
A nitro engine generally refers to an engine powered with a fuel that contains some portion (usually between 10% and 40%) of nitromethane mixed with methanol.Nitromethane is a highly combustible substance that is generally only used in very specifically designed engines found in Top Fuel drag racing and in miniature internal combustion engines in radio control, control line and free flight ...
Most methanol-fueled model engines, especially those made outside North America, can easily be run on so-called FAI-specification methanol fuel. Such fuel mixtures can be required by the FAI for certain events in so-called FAI "Class F" international competition, that forbid the use of nitromethane as a glow engine fuel component. In contrast ...
A glow plug engine, or glow engine, is a type of small internal combustion engine [1] typically used in model aircraft, model cars and similar applications. The ignition is accomplished by a combination of heating from compression, heating from a glow plug and the catalytic effect of the platinum within the glow plug on the methanol within the ...
In 1950 Roy ventured into engine manufacturing by teaming up with Mel Anderson to produce the O-Forty-Five Special car. This engine was .045 cubic inch and used some parts from Mel Anderson's Spitzy model airplane engine, however the bulk of the engine was Cox's design. In the same year, Roy had noticed the appeal of model airplanes to young ...
