If you're a fan of radio-controlled vehicles, but find standard
RC to be lacking in power and running time, you might want to
consider looking into gas powered RC cars. These cars, which run
on a nitromethane-based fuel that is often referred to as "glow
fuel" or "nitro", offer a level of realism and performance that
you just won't find on battery powered cars. Gas powered RC cars
are also often highly customizable, allowing hobbyists to
utilize a variety of engines and design types... there are even
different types of transmitters available depending upon how you
would prefer your car to work. Below are some of the options
available for gas powered RC cars, giving you an idea of the
level of customization that you can achieve.
Engines Obviously, one of the more important aspects of
gas powered RC cars is the engine. A variety of different engine
models are available for you to choose from, but in general most
cars of this type will have what are commonly referred to as
"glow" engines. A "glow" engine is a 2-cycle internal combustion
engine, creating the power that gas powered RC cars are known
for and adding a bit of realism to the car with the exhaust that
is produced. Instead of the spark plugs that a full-size
automotive engine would have, these engines use a "glow plug"
that is heated by what is known as a "glow starter" This heat is
then held by the plug and is used to fire the engine strokes for
the remainder of the running time.
Fuel As mentioned above, the "gas" used by gas powered RC
cars isn't actually gasoline... it's a special fuel that is
nitromethane-based and formulated for the cars' engines. Special
lubricants are added to the fuel mixture to protect the engine
from excessive heat and wear; the lubricants work in much the
same way as gas-oil mixtures in some chainsaws and other
small-engine equipment. Other fuel accessories may be needed to
go with your car. A pump or special bottle may be used to get
the fuel into the RC car's fuel tank, and filters in the fuel
line may need to be replaced from time to time.
Radio The radio that you use to control your gas powered
RC cars can be the same type that is used to control an electric
model of RC car. A 2-channel radio system. It's important to
keep in mind that just because the car's engine runs on a liquid
fuel doesn't mean that you have no need of batteries. In
addition to the battery that powers the radio controller, you
might find yourself in need of batteries to supply power to the
radio receiver in the car itself. Of course, with some receivers
it may be possible to have the power supplied by the motor of
the car itself. The type of receiver that you use and the power
supply that it needs are one consideration to keep in mind when
comparing different parts or different cars.
Sport vs. Competition A variety of different options and
body styles exist for gas powered RC cars. You can choose from
trucks, sedans, buggies, popular car models, and even stock
cars. Once you've decided upon the body style and layout that's
right for you, however, you may find yourself facing one
additional choice. Many of the car models available commercially
come in two distinct types; a sport version, and a competition
version. Sport cars tend to cost less, and offer basic options
that are popular with beginners and casual hobbyists. For those
who want to race their cars against other dedicated hobbyists,
though, there are the competition cars which tend to have more
power and higher speeds and offer advanced options such as oil
shocks and ball bearings. Competition models may not be a
complete car, however, since they are designed to allow for more
customization... many of these kits require you to get the
engine that you want to go with it separately, as well as the
car body in many cases (since the kit only provides the main
chassis.)
Kits vs. RTR If you've decided that you want to buy gas
powered RC cars, you often have to make a choice between buying
a kit, so that you can build the car yourself, or buying a
ready-to-race car (also known as RTR) that is ready to be fueled
and go right out of the box. RTR cars are good for beginners or
casual hobbyists, but aren't highly customized. Kits, on the
other hand, may require additional work but allow the builder to
decide exactly how they want their car put together. Should you
use a kit, it's important to remember that you'll need to make
sure that you have the engine that you want, paint and basic
tools on hand for assembly and decoration, and additional tools
and parts depending upon the kit that you purchase. Regardless
of the type of car that you buy, though, you're certain to find
yourself amazed at the power and performance of these cars loved
by hobbyists and racers around the world.
