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.

Failure to follow these instructions will be considered as abuse and/or neglect.

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 short­circuits, 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.

QUALITY CERTIFICATE

XRAY MODEL RACING CARS uses only the highest quality materials, the best
compounds for molded parts and the most sophisticated manufacturing processes
of TQM (Total Quality Management). We guarantee that all parts of a newly­purchased kit are manufactured with the highest regard to quality. However, due
to the many factors inherent in model racecar competition, we cannot guarantee

any parts once you start racing the car. Products which have been worn out,
abused, neglected or improperly operated will not be covered under warranty.
We wish you enjoyment of this high-quality and high-performance RC car and
wish you best success on the track!

In line with our policy of continuous product development, the exact specifications of the kit may
vary. In the unlikely event of any problems with your new kit, you should contact the model shop
where you purchased it, quoting the part number.
We do reserve all rights to change any specification without prior notice. All rights reserved.

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.

All three bushings MUST have same orientation.
These bushings adjust the front CASTER:

These eccentric bushings adjust the front CASTER.
MORE caster angle = better cornering speed, increased traction rolling.
Use on big, open tracks where cornering speed is needed.
LESS caster angle = more reactive steering. Use on technical tracks where
a lot of steering response is needed.

The more camber angle, the more steering there is. However, it makes the car
more sensitive and more difficult to drive.
Use LESS camber angle for carpet and other high-traction tracks.
Use MORE camber on asphalt and low-traction tracks.

The number of the shims affects
the front ride height. Determine
the proper amount of shimming
based on tire diameter.

After assembling the steering block, loosen

then use your other fingers to pull up the
steering block. Then tighten the set-screw.
