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 ngers or any objects inside rotating and moving parts, as this may cause damage or
serious injury as your 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, 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.

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 lter is clean and oiled.
• Never run your engine without an air 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 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 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 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 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 recti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 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 re.

Products may potentially have small amounts of corrosion on them. This may be caused by variances in
weather during different times of the year, humidity in the shop or during shipping, and other contributing
factors. Even though we have taken all precautions and protection methods to prevent corrosion, these small
amounts of corrosion (if present) are unavoidable and considered to be acceptable.

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 difculty 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 re
or explosion, and ruin your engine.
• Nitro fuel is highly inammable, explosive, and poisonous. Never use fuel indoors or in places with open
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 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 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 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 res or explosions.
• Do not dispose of fuel or empty fuel containers in a re. There is danger of explosion.

During initial assembly, tighten each composite hex nut until the pivot
ball starts to bind, then loosen slightly.
Verify that the pivot balls move freely.
Tighten composite hex nuts
using HUDY

Follow the TECH TIP on page
31 to install the pivot balls
When you use INNER position on the
upright, use SHORTER ball joint.
