A Guide To Gas Powered Rc Cars
By Greg Root, Fri Dec 9th
Gas Powered RC cars offer many realistic features and come in avariety of types and styles. To help you choose what's right foryou, this article covers the main considerations you'll face. If you're a fan of radio-controlled vehicles, but find standardRC to be lacking in power and running time, you might want toconsider looking into gas powered RC cars. These cars, which runon a nitromethane-based fuel that is often referred to as "glowfuel" or "nitro", offer a level of realism and performance thatyou just won't find on battery powered cars. Gas powered RC carsare also often highly customizable, allowing hobbyists toutilize a variety of engines and design types... there are evendifferent types of transmitters available depending upon how youwould prefer your car to work. Below are some of the optionsavailable for gas powered RC cars, giving you an idea of thelevel of customization that you can achieve. Engines Obviously, one of the more important aspects of gaspowered RC cars is the engine. A variety of different enginemodels are available for you to choose from, but in general mostcars of this type will have what are commonly referred to as"glow" engines. A "glow" engine is a 2-cycle internal combustionengine, creating the power that gas powered RC cars are knownfor and adding a bit of realism to the car with the exhaust thatis produced. Instead of the spark plugs that a full-sizeautomotive engine would have, these engines use a "glow plug"that is heated by what is known as a "glow starter" This heat isthen held by the plug and is used to fire the engine strokes forthe remainder of the running time.
Fuel As mentioned above, the "gas" used by gas powered RC carsisn't actually gasoline... it's a special fuel that isnitromethane-based and formulated for the cars' engines. Speciallubricants are added to the fuel mixture to protect the enginefrom excessive heat and wear; the lubricants work in much thesame way as gas-oil mixtures in some chainsaws and othersmall-engine equipment. Other fuel accessories may be needed togo with your car. A pump or special bottle may be used to getthe fuel into the RC car's fuel tank, and filters in the fuelline may need to be replaced from time to time. Radio The radio that you use to control your gas powered RC carscan be the same type that is used to control an electric modelof RC car. A 2-channel radio system. It's important to keep inmind that just because the car's engine runs on a liquid fueldoesn't mean that you have no need of batteries. In addition tothe battery that powers the radio controller, you might findyourself in need of batteries to supply power to the radioreceiver in the car itself. Of course, with some receivers itmay be possible to have the power supplied by the motor of thecar itself. The type of receiver that you use and the powersupply that it needs are one consideration to keep in mind whencomparing different parts or different cars.
Sport vs. Competition A variety of different options and bodystyles exist for gas powered RC cars. You can choose fromtrucks, sedans, buggies, popular car models, and even stockcars. Once you've decided upon the body style and layout that'sright for you, however, you may find yourself facing oneadditional choice. Many of the car models available commerciallycome in two distinct types; a sport version, and a competitionversion. Sport cars tend to cost less, and offer basic optionsthat are popular with beginners and casual hobbyists. For thosewho want to race their cars against other dedicated hobbyists,though, there are the competition cars which tend to have morepower and higher speeds and offer advanced options such as oilshocks and ball bearings. Competition models may not be acomplete car, however, since they are designed to allow for morecustomization... many of these kits require you to get theengine that you want to go with it separately, as well as thecar body in many cases (since the kit only provides the mainchassis.) Kits vs. RTR If you've decided that you want to buy gas poweredRC cars, you often have to make a choice between buying a kit,so that you can build the car yourself, or buying aready-to-race car (also known as RTR) that is ready to be fueledand go right out of the box. RTR cars are good for beginners orcasual hobbyists, but aren't highly customized. Kits, on theother hand, may require additional work but allow the builder todecide exactly how they want their car put together. Should youuse a kit, it's important to remember that you'll need to makesure that you have the engine that you want, paint and basictools on hand for assembly and decoration, and additional toolsand parts depending upon the kit that you purchase. Regardless of the type of car that you buy, though, you'recertain to find yourself amazed at the power and performance ofthese cars loved by hobbyists and racers around the world.
