This Century UK- BSD car is very tough, but it is not indestructible. In common with all R/C
cars, stresses and vibrations cancause screws and fastenings to work loose. It is your
responsibility to carry out regular checks, tighten screws where necessary and generally
maintain the car to ensure optimum performance and reliability.
This high performance radio-controlled car is not a toy. Used incorrectly it is capable of
inflicting serious harm to persons or property. It is not recommended for use by children
under 14 years of age unless supervised by a suitably experienced adult.Please read the
contents of this manualprior to operating. If you are uncertain regarding any aspect of its
safe operation please contact your Century UK - BSD dealer to seek help or advice.
IMPORTANT NOTICE
SAFETY PRECAUTIONS
Features:

Equipment required for operation
1. Tools required for maintenance:
2.Further items required:
Do not use a power screwdriver to remove, install or tighten any screws that locate into
plastic moulded parts. The high operating speed of these tools may cause the threads in
the plastic mouldings to be damaged or stripped.
WARNING!
IMPORTANT!
Regularly check all screws and fasteners are secure before operating this model. We
recommended the application of a small amount of thread-lock to screws that work
loose from metal components.
8 pcs AA alkaline
batteries for transmitter.

Channels : 2
Model Type : Car/Boat
Frequency : 2.4GHz
Power :12V DC (8 x AA batteries)
Charging Port : Built-in (centre pole +)
Low Voltage Warning : Yes (below 9V)
Transmitter Specifications:
The antenna on the receiver must be
positioned vertically to achieve optimum
range(Figure 1).It must be kept away from
any metallic or carbon components.
Note:
Your Century UK-BSD car features a quality 2.4 GHz radio control system. Under normal circumstances it is
virtually immune to interference from other radio controlled models. All 2.4GHz systems are required to
undergo a process called “binding”. This is where a receiver is programmed only to respond to commands
from one unique transmitter. The binding process has already been carried out at the factory by default.
Under certain circumstances it may be necessary for a 2.4GHz system to require a re-bind. In this event,
please refer to the following instructions.
Transmitter Operation:
1. Ensure you have fresh batteries installed in the transmitter.
2. Insert the “bind-plug” into the port on the receiver marked: CH3. (Figure 2).
3. Connect a receiver battery (4.8V DC) to the receiver port marked VCC. The two LEDs on the receiver will flash
rapidly, indicating that it has entered the binding mode.
4. Press and hold the bind button on the transmitter, and simultaneously turn on the power switch.Note: The
bind button is recessed to prevent accidental operation.
5. Continue to hold the bind button. After approx. 5
seconds the receiver LEDs will stop flashing, indicating
that binding has taken place.
6. Release the bind button on the transmitter and remove
the binding plug from the receiver.
7. Connect the steering servo to the receiver and operate
the steering function on the transmitter to test the system.
8. If the test is successful, remove the power supply from
the receiver port marked VCC.
9. The binding process is now complete.
Binding:
When operating the model, always comply
with the following procedure:
1. Turn on the power switch on the transmitter first.
2. Connect the power supply to the receiver.
3. The receiver LED should illuminate without flashing.
4. Follow engine starting procedure.
Turn On:
Bind Button
Bind Plug

1. Stop the engine.
2. Disconnect the receiver power supply.
3. Turn off the transmitter.
Turn Off:
Failure to comply with this procedure could result
in a total loss of control.
Transmitter Functions:
IMPORTANT
The trigger function
controls the speed of the vehicle.
Position the car so the wheels are not touching the ground before starting the engine.
Check before you drive that the model is responding in the correct manner to your
transmitter, i.e. moving the steering wheel to left will result in the car turning to the left.
Check the position of the steering and throttle trims before driving, failure to do so could
result in the car not responding to controls as expected.
Check the power level of your transmitter batteries prior to use. Driving with exhausted
batteries could lead to a loss of control.
ALWAYS:
Never drive it close to other people or property.
Never operate this model on public roads.
Never operate this car in the rain, drive through puddles or wet grass. Water could seriously
damage the electronic systems.
Never touch the motor after the car has been driven, it will get very hot.
NEVER:
The steering function
controls the direction of the model.
Dual Rate DSC FOR SIMULATOR
Keep long hair and loose clothing away from all moving parts of the car.
Look after the car by keeping it clean and free from dust or dirt.

MAIN MIXTURE CONTROL NEEDLE
IDLE STOP SCREW
IDLE STOP
SCREW
MAIN MIXTURE
CONTROL NEEDLE
The main mixture control needle points upwards from the carburettor
(see image). It controls the fuel/air mixture supplied to the engine.
The needle is factory set for runningin, at 2 1/2 turns out (anti-clockwise)
from its fully closed position. Once run in, the main mixture control
needle would typically be set2 and 2-1/2 turns out from fully closed.
You should be aware that the main mixture control needle settings will
require small adjustment dependingon the temperature, humidity and
even the altitude above sea level.
The idle stop screw is located towards the rear of the carburettor
(see image). The purpose of this screw is to set the speed at which
the engine idles or “ticks over”. It has no effect on the mixture control
settings of the engine and has been pre-set at the factory to default
settings. With the air filter removed, you will be able to see the barrel
inside the carburettor. With the throttle set to idle, the gap visible on the
barrel should be around 1mm. Any changes to the idle speed of the engine
will require only very minor adjustment of this screw. We recommend that
the screw is set to allow the engine to idle at the lowest speed possible.
Running the engine with an excessively high idle speed could result in the
centrifugal clutch partially engaging. This could result in premature wear of the brakes or a
complete failure of the clutch assembly. After making any adjustments replace the air filter
immediately. Never operate the car without the air filter fitted to the carburettor.
1. Fill the fuel tank withfresh model “nitro” fuel containing no more than 20% nitromethane.
2. To prime the engine when cool, place your finger over the tuned pipes exhaust exit and
gently pull the pull start several times. You will notice that fuel will travel through the fuel
line towards the carburettor. Be careful not to over-prime. You should stop priming when
the fuel reaches the carburettor.
3. Ensure that your glow start (not included) is fully charged and attach to the glow plug
ituated in the cylinder head of the engine.
4. With the throttle set to idle, start the engine by pulling the recoil starter handle using short,
quick pulls. Do not pull the recoil starter out to its maximum. If you do, it is most likely that
you will weaken the pull start return mechanism and it could fail entirely.This will not be
covered by the warranty on your car.You only need to pull the starter out to a maximum of
around 20cms or 8”. Sometimes when the engine is already hot, it can be easier to start the
engine at a higher throttle setting (1/4 to ½throttle). When the engine starts immediately
return the throttle setting to idle. Failure to do this can cause the engine to over –rev and
cause serious damage.
The radio system must always be switched on and operational when the engine
is started. Never switch off the transmitter or receiver with the engine running.
