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 fingers or any objects inside rotating and moving parts, as this may cause damage or
serious injury as your finger, 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, flying 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.
• When learning to operate your model, go to an area that has no obstacles that can damage your
model if your model suffers a collision.
• Remove any sand, mud, dirt, grass or water before putting your model away.
• If the model behaves strangely, immediately stop the model, check and clear the problem.
• To prevent any serious personal injury and/or damage to property, be responsible when operating all
remote controlled models.
• The model car is not intended for use on public places and roads or areas where its operation can
conflict with or disrupt pedestrian or vehicular traffic.
• Because the model car is controlled by radio, it is subject to radio interference from many sources that
are beyond your control. Since radio interference can cause momentary loss of control, always allow a
safety margin in all directions around the model in order to prevent collisions.
• 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
residential areas.
- At night or anytime your line of sight to the model may be obstructed or
impaired in any way.
To prevent any serious personal injury and/or damage to property, please be
responsible when operating all remote controlled models.

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 fire. 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 fire 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 fire. 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 rectified 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 finished.
• 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 fire.

and the most sophisticated manufacturing processes of TQM (Total Quality Management). We guarantee
that all parts of a newly-purchased kit are manufactured with the highest regard to quality. However, due

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 difficulty finding 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.

After assembling the steering block, do the following:
1. Loosen the set-screw slightly.
2. Use your thumb to press down on the top of the kingpin, while
using your other fingers to pull up the steering block.
3. Tighten the set-screw.

The angle of the side tubes has a fine effect on car performance.
The angle is adjusted with shims between the pivot ball and the rear
brace and/or upper plate.
The HIGHER the angle, the stiffer it feels and the less it rolls.
The LESS (flatter) the angle, the softer it feels and the more it rolls.
OPTIONAL SIDE SHOCK
#378100 - Optional side shock can be used to improve
traction in low- and medium-traction conditions.
The optional side shock REPLACES the 2 side tubes.

Add oil in each slot of the COMPOSITE side shock tubes.
NOTE:
Add oil only in the slots, not on the whole tube.
After assembling the side tubes, check for smooth operation.
It is very important to re-oil the side tubes, at least once per race day.
You may use different oil thicknesses depending on track conditions.

3x5x0.5mm
The thickness of these shims affects rear ride height, so determine the proper amount
of shimming based on tire diameter.
IMPORTANT: Always use the same thickness of shims on both left & right sides.
For INITIAL SETTING, use (2x) 3x5x0.5mm on both left & right sides.
Optionally included: (4x) 3x5x0.25mm shims for fine tuning.
A SHORTER car rotates harder in slow
corners and has improved forward traction.
A LONGER car is more free in high-speed
corners and will feel more linear, especially
during fast direction changes.
