For Gas Powered Remote Control Cars
If you are getting started into gas powered
rc cars, this page will explain all the items and accessories you need
to get started.
|Gas Powered Car
First item to buy is the car itself. There are plenty to choose from...
personally I prefer 1/10th scale touring nitro cars.
Touring cars have 4 wheel independent
suspension, 4 wheel drive, and 2-speed transmissions capable of
propelling car to speeds in excess of 50 mph.
Gas powered cars use 2-stroke engines. For 1/8 scale, .21 size engines
are used. For 1/10 scale, .12 size engines are common.
Note that the engines can come either
pull-start (PS) or non-pull start. Pull-start engines have a build in
recoil starter, just pull the wire or rope to turn the engine's
For non-pull start engines, you will need
have a starter. The end of the starter is a rubber wheel, which is
"bumped" against the flywheel of the engine to turn the crankshaft.
Warning: do not use a starter on a
pull-start engine, you may damage the pull-start mechanism.
These are specially blended fuel for rc gas cars. Be careful, the fuel
used for model airplanes is different. Be specific in requesting for
fuel for rc gas cars.
Fuel is also classified according to
content. The higher the nitro content, the more power. I personally use
fuel with only 10% nitro, I find this is good enough to win races, and
is cheaper than fuel with 15 - 20% nitro.
Driver or Igniter
The nitro engines use a glow plug (similar to a spark plug of a real
engine). To start the engine, this glow plug must be heated.
A device called a glow driver or igniter,
powered by a 1.5v battery, is used to heat the glow plug.
The radio control unit is the electronics that control the speed and
direction of the car. A basic radio controller consists of the
c. servos (2)
d. batter holder for the receiver
e. on/off switch
f. servo horns
Batteries and Charger
The transmitter (pictured above) needs 8AA sized batteries to produce
Rechargeable batteries will work, just
that a single rechargeable AA batteries produces only 1.2
volts (alkaline produce 1.5 volts).
Using 8AA rechargeable batteries will
produce 9.6 volts, slightly less voltage than the ideal 12 volts.
Still, most transmitters will work fine with 9.6 volts.
Radio System Setup
This is the basic radio system setup that is
mounted inside a gas car or nitro rc truck. The receiver (1) sends
signals to the servo that controls the speed (3) and the servo that
controls the steering (4).
The receiver is powered by 4-AA sized
batteries (5) with an on/off switch (6).
Item (2) is a Futaba fail safe unit.
Inserted between the servo and receiver, this optional item is very
useful in fast gas powered cars. Basically if there is radio
interference, the fail safe will reset the servo to a specific setting,
for example in the braking position. So if there is any radio
interference, the car will brake instead of going out of control.
Tips: Never, ever, cut the receiver antenna
(wire). I know it is long... but trust me, do not cut it because it
will cause your car to go out of control.
Buy a fail safe unit... it is an inexpensive
option that can save your gas car from damage. (There was a time when
we were playing on the roof deck of a parking lot, 6 floors above
ground level. One of the cars lost control, flew into the air, and fell
6 stories onto the roof of a parked Toyota Corolla. A fail safe unit
could have prevented this from happening).
