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.
• 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 conict with or disrupt pedestrian or vehicular trafc.
• 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 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.

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.

DO NOT TIGHTEN THE DIFF COMPLETELY
THE DIFF MUST BE BROKEN IN PROPERLY !
 When you build the differential, do not tighten it fully initially; the differential needs to be broken in properly. When you build the diff tighten it very gently.
When you put the diff in the car and complete the assembly, run the car for a few minutes, tighten the diff a little bit, and then recheck the diff. Repeat this process
several times until you have the diff tightened to the point you want it. Final adjustments should ALWAYS be made with the diff in the car and on the track.

Longer drive shafts (52mm) make the car easier to drive because they
give more traction and better stability, mainly in chicanes. However, the
car will understeer more than with shorter (50mm) shafts which give a
lot of steering and impart aggression to the car. You may also combine
different lengths of shafts in front and rear (for example, using long shafts
in the rear and short shafts in the front) depending on track conditions.
Both left & right shafts should ALWAYS be the same length at one end of
the car (front or rear).
52mm shafts are recommended for carpet and big asphalt tracks
50mm shafts are recommended for small-medium tight asphalt tracks
DO NOT use the plastic caps with
composite solid axle included in the kits.
The new #305241 3.5mm plastic caps
are for use ONLY with ALU ball diffs or
the XRAY Multi-Diff™.
ECS shafts are available optionally in both
50mm and 52mm lengths. The ECS drive
shafts were developed to decrease front wheel
vibration when racing with a solid front axle,
thus providing a much smoother and quieter
ride and increased steering.

An optional 1-hole rear upright is
available for fine tuning. This optional
upright may be used on high-traction
tracks or tracks with long sweepers, since
the position of the center hole will allow
faster driving through those corners
because of better cornering speed.

After you tighten the screw
into the upright, pull the
linkage upward so the ball
joint " snaps " onto the pivot
ball. The whole assembly

When the bars are set, verify that both sides move at the same
time. If yes, the bars are set up correctly. If not, make sure that both
downstops are the same and that the bar wire is flat.

The number of shims changes the angle
of the steering linkage. When is no
shim used, car is easy to drive into the
corner. The number of shims increases
in-cornersteering but makes the car more
difficult to drive.

Initial position =  ball
Use the  ball on low-traction tracks (mainly low-traction carpet tracks).
The car will have more traction & more steering, but will be more difficult to drive
because the car will roll more. Recommended on chicane tracks.
Use the  ball on low- to medium-traction tracks (asphalt, carpet). The car
will have a little less rear traction and the car will roll little less which will make it
easier to drive with more cornering speed.
Use the  ball on high-traction tracks (mainly high-traction asphalt tracks).
The car will roll even less which will allow the use of more throttle in the corners,
however the car will have less traction.
