IMPORTANT NOTES – GENERAL

• This product is not suitable for children under 16 years of age without the direct
supervision of a responsible and knowledgeable adult.

• Carefully read all manufacturers warnings and cautions for any parts used in the
construction and use of your model.

• Assemble this kit only in places away from the reach of very small children.

• First-time builders and users should seek advice from people who have building
experience in order to assemble the model correctly and to allow the model to reach
its performance potential.

• Exercise care when using tools and sharp instruments.

• Take care when building, as some parts may have sharp edges.

• Keep small parts out of reach of small children. Children must not be allowed to put
any parts in their mouth, or pull vinyl bag over their head.

• Read and follow instructions supplied with paints and/or cement, if used (not
included in kit).

• Immediately after using your model, do NOT touch equipment on the model such
as the motor and speed controller, because they generate high temperatures. You
may seriously burn yourself seriously touching them.

• Follow the operating instructions for the radio equipment at all times.

• Do not put fi ngers or any objects inside rotating and moving parts, as this may
cause damage or serious injury as your fi nger, hair, clothes, etc. may get caught.

• Be sure that your operating frequency is clear before turning on or running your
model, and never share the same frequency with somebody else at the same time.
Ensure that others are aware of the operating frequency you are using and when
you are using it.

• Use a transmitter designed for ground use with RC cars. Make sure that no one
else is using the same frequency as yours in your operating area. Using the same
frequency at the same time, whether it is driving, fl ying or sailing, can cause loss of
control of the RC model, resulting in a serious accident.

• Always turn on your transmitter before you turn on the receiver in the car. Always
turn off the receiver before turning your transmitter off.

• Keep the wheels of the model off the ground when checking the operation of the
radio equipment.

• Disconnect the battery pack before storing your model.

• Do not use your model:

- Near real cars, animals, or people that are unaware that an RC car is being
driven.

- In places where children and people gather

- In residential districts and parks

- In limited indoor spaces

- In wet conditions

- In the street

- In areas where loud noises can disturb others, such as hospitals and

IMPORTANT NOTES – NITRO ENGINES

• Always test the brakes and the throttle before starting your engine to avoid losing
control of the model.

• Make sure the air fi lter is clean and oiled.

• Never run your engine without an air fi lter. Your engine can be seriously damaged
if dirt and debris get inside the engine.

• For proper engine break-in, please refer to the manual that came with the engine.

• Do not run near open fl ames or smoke while running your model or while handling
fuel.

• Some parts will be hot after operation. Do not touch the exhaust or the engine until
they have cooled. These parts may reach 275°F during operation!

IMPORTANT NOTES – ELECTRICAL

• Insulate any exposed electrical wiring (using heat shrink tubing or electrical tape)
to prevent dangerous short circuits. Take maximum care in wiring, connecting
and insulating cables. Make sure cables are always connected securely. Check
connectors for if they become loose. And if so, reconnect them securely. Never use
R/C models with damaged wires. A damaged wire is extremely dangerous, and can
cause short-circuits resulting in fi re. Please have wires repaired at your local hobby
shop.

• Low battery power will result in loss of control. Loss of control can occur due to a
weak battery in either the transmitter or the receiver. Weak running battery may also
result in an out of control car if your car‘s receiver power is supplied by the running
battery. Stop operation immediately if the car starts to slow down.

• When not using RC model, always disconnect and remove battery.

• Do not disassemble battery or cut battery cables. If the running battery short-circuits,
approximately 300W of electricity can be discharged, leading to fi re or burns. Never
disassemble battery or cut battery cables.

• Use a recommended charger for the receiver and transmitter batteries and follow

the instructions correctly. Over-charging, incorrect charging, or using inferior
chargers can cause the batteries to become dangerously hot. Recharge battery when
necessary. Continual recharging may damage battery and, in the worst case, could
build up heat leading to fi re. If battery becomes extremely hot during recharging,
please ask your local hobby shop for check and/or repair and/or replacement.

• Regularly check the charger for potential hazards such as damage to the cable,
plug, casing or other defects. Ensure that any damage is rectifi ed before using
the charger again. Modifying the charger may cause short-circuit or overcharging
leading to a serious accident. Therefore do not modify the charger.

• Always unplug charger when recharging is fi nished.

• Do not recharge battery while battery is still warm. After use, battery retains heat.
Wait until it cools down before charging.

• Do not allow any metal part to short circuit the receiver batteries or other electrical/
electronic device on the model.

• Immediately stop running if your RC model gets wet as may cause short circuit.

• Please dispose of batteries responsibly. Never put batteries into fi re.

R/C & BUILDING TIPS

• Make sure all fasteners are properly tightened. Check them periodically.

• Make sure that chassis screws do not protrude from the chassis.

• For the best performance, it is very important that great care is taken to ensure the
free movement of all parts.

• Clean all ball-bearings so they move very easily and freely.

• Tap or pre-thread the plastic parts when threading screws.

• Self-tapping screws cut threads into the parts when being tightened. Do not use
excessive force when tightening the self-tapping screws because you may strip out
the thread in the plastic. We recommended you stop tightening a screw when you
feel some resistance.

• Ask your local hobby shop for any advice.

Please support your local hobby shop. We at XRAY Model Racing Cars support all local
hobby dealers. Therefore we ask you, if at all possible, to purchase XRAY products at
your hobby dealer and give them your support like we do. If you have diffi culty fi nding
XRAY products, please check out www.teamxray.com to get advice, or contact us via
email at [e-mail], or contact the XRAY distributor in your country.

IMPORTANT NOTES – NITRO FUEL

• Handle fuel only outdoors. Never handle nitro fuel indoors, or mix nitro fuel in a
place where ventilation is bad.

• Only use nitro fuel for R/C models. Do not use gasoline or kerosene in R/C models
as it may cause a fi re or explosion, and ruin your engine.

• Nitro fuel is highly infl ammable, explosive, and poisonous. Never use fuel indoors
or in places with open fi res and sources of heat.

• Always keep the fuel container cap tightly shut.

• Always read the warning label on the fuel container for safety information.

• Nitro-powered model engines emit poisonous vapors and gasses. These vapors irritate
eyes and can be highly dangerous to your health. We recommend wearing rubber or vinyl
gloves to avoid direct contact with nitro fuel.

• Nitro fuel for RC model cars is made of the combination of the methyl alcohol,

castor or synthetic oil, nitro methane etc. The fl ammability and volatility of these
elements is very high, so be very careful during handling and storage of nitro fuel.

• Keep nitro fuel away from open fl ame, sources of heat, direct sunlight, high
temperatures, or near batteries.

• Store fuel in a cool, dry, dark, well-ventilated place, away from heating devices,
open fl ames, direct sunlight, or batteries. Keep nitro fuel away from children.

• Do not leave the fuel in the carburetor or fuel tank when the model is not in use.
There is danger that the fuel may leak out.

• Wipe up any spilled fuel with a cloth

• Be aware of spilled or leaking fuel. Fuel leaks can cause fi res or explosions.

• Do not dispose of fuel or empty fuel containers in a fi re. There is danger of
explosion.

Place the pivot ball on the
ball joint and use a screw
to tighten it to an engine
mount or some other part.

In the event that the composite diff bulkhead allows too much diff side play, this may create non-optimal gear mesh between the diff spur gear and the
pinion drive gear. This is easily resolved by inserting 1 or 2 of the included thin shims behind a diff outdrive ball-bearing, depending on how much play
there is.

FRONT & REAR DIFF GEAR MESH ADJUSTMENT

THE LOCATION OF THE SHIM(S) DEPENDS ON WHETHER YOU ARE TRYING TO CLOSE OR OPEN THE GAP:

To close a wide gap: add 1 or 2
shims against diff spur gear

TO CLOSE A WIDE GAP

TO OPEN A NARROW GAP

To open a narrow gap: add 1 or 2
shims on the other side of the diff,
away from spur gear
