Instruction manual

IMPORTANT: There are multiple radio frequencies that are used on RC vehicles. Make 100% sure that before
you switch on your radio, that there are no other RC vehicles being operated in the area. By switching on your
radio while another vehicle is being operated on the same frequency can cause damage to that vehicle or injury
to others in the area. When 2 radios are being operated on the same frequency and within range,the vehicle
will not know which radio is controlling it and usually causes the vehicle to run out of control.
N OTE: Always turn the remote control power on before the vehicle.
Precaution: If your vehicle glitches (a sporadic movement of the vehicle without any use of the remote
control) you should first make sure that nobody else is on the same frequency as you. If no others were on
the same frequency, you should take the vehicle to a clear area or field where they are no electrical power
lines. Power lines, cell towers and other things can cause interference with your vehicle and you should
always test your vehicle prior to running to make sure these things don't exist.

combustion chamber in the middle of the Head. An element inside of it glows red hot when a current is put
through it, which sparks the fuel. This element is powered by your glow igniter. If this element burns out,
the engine will not start. This will be the most replaced part on your vehicle.
Carburetor- The carburetor is what controls the speed of your motor. It intakes air and fuel into the Engine.
The carburetors main job is to control the mixture of air and fuel as it enters the engine.You control this
mixture through the needle adjustments on the carburetor. The optimal air and fuel ratio rarely changes,
however changes in Temperature, Altitude, and Humidity all can effect this mixture. For example, when it is
cold outside there are more air molecules per square inch than there are when its warmer out. To correct this
you would need to adjust your mixture so that it allows more fuel to counter the increase in air molecules. In
order to do this you would richen your needle. Some people call richening, “Fattening.” If
High Speed Needle (HSN) - The High Speed Needle is used to control the mixture of fuel and air when the
carburetor is open from partial throttle to Full throttle.
Low Speed Needle (LSN) - The Low Speed Needle is used to control the mixture of fuel and air when the
carburetor is at idle to partial throttle.
Idle Screw- The idle screw controls how much fuel and air the carburetor lets into the engine while you are
in neutral. You want to set this as low as possible while still allowing the engine to idle for a good amount
of time.
Air Filter Housing - This houses the air filter and funnels air into the carburetor.
Air Filter- This protects your engine from dust and harmful debris. It should be cleaned and oiled, or replaced
often. Any dirt or fine dust entering the engine can cause performance loss or irreversible damageThe air filter.
can look clean to the eye, but still contain harmful microscopic dust that can harm the engine. Err on the side
caution when deciding when to clean your air filter. It can be oiled using air filter oil from a hobby shop. Air
of filter oil for off-road motorcycles and ATVs will also work,and can be purchased from most Motorcycle
and ATV stores.

The radio receiver is located in the receiver box
on the car.There are usually 3 outlets that
connections are plugged into.These are labeled
as Channel 1,Channel 2 and Battery.Make
sure all are seated correctly and firmly in place.
The receiver also houses a crystal.The crytal frequency will match to the
crystal in your remote.You can always change these with another frequency
if you have another car on the same one.
Cylinder Head - This sits on top of the case, and helps to dissipate heat.
Case- Houses all the internal components of the engine.
Crankshaft- The crankshaft is connected to the connecting rod and piston, and gets spun by the up and
down movement of the piston. The flywheel and clutch bell sit on the crankshaft and all of them spinning
together is what turn the gears of the transmission.
- The piston is precisely fitted with the sleeve of the motor to create compression needed for the
fuel to combust. It moves up and down inside the sleeve, turning the crankshaft.
Connecting Rod - This is what connects the piston to the crankshaft.
Glow Plug - This is what is used to start the combustion process in your motor. It sits on top of the

B efore you fire up your vehicle and break in your motor, you should familiarize yourself with it.
Understanding your motor and how it works, will make it much easier to tune, maintain, and keep it running
at maximum efficiency for a long time.

smaller or slightly different, but they all work in basically the same way.
