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 RC 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.

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 newly-purchased 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.

FRONT WHEELBASE ADJUSTMENT
Longer wheelbase is recommended for bigger tracks
with longer sweepers. Makes the car more stable and
easier to drive.
Shorter wheelbase allows the car to rotate better in corner
to maintain cornering speed. Recommended for tight,
technical tracks or tracks with numerous 180° hairpin
corners.
CASTER ADJUSTMENT SETTING
Caster is adjusted by the shims placed

FORWARD POSITION (INITIAL SETTING)
Initial setting for most tracks provides a neutral steering
feel similar to that of the old X12. Provides a good
balance between initial response and cornering speed.
REARWARD POSITION
Makes the car freer because of increased Ackermann
(less steering lock on the outer wheel in relation to the
inner). Recommended for medium- to high-traction
tracks.

CAMBER ADJUSTMENT
EU Edition kits include the 1.5º kingpins; US
Edition kits include the 1.0º kingpins. These are
the recommended start points for low to medium
grip (EU) or high grip (US) conditions. Optional
kingpins are available to adjust camber if needed.
DECREASING THE CAMBER ANGLE
will decrease the steering which will make the car easier
to drive and also helps to prevent traction rolling.

The front suspension parts were updated
to eliminate play to ensure better steering
performance. The updated holes in the
steering blocks may cause a tighter fit
of the kingpin in the steering block; it is
important that the steering block moves
freely but without excessive play. If the
kingpin does not insert into the steering
block easily, use a 4mm Arm Reamer
to enlarge the hole. Be very careful to
remove only enough material so you can
insert the kingpin without a lot of force.

SOFTER SPRINGS
Makes the car easier to drive over bumps and
increases steering as it makes the car roll more,
especially in the middle of a corner.
HARDER SPRINGS
Makes the car more responsive and increases initial
steering. Recommended for high-traction and flat
tracks.
MORE DROOP
will make the car initially less responsive, but it will give the car more front grip,
especially in the middle of the corner. The car will be less precise and more difficult to drive, because of
increased roll. More droop is best suited for low- to medium-traction carpet, or asphalt.
LESS DROOP
will decrease roll but the car will change direction quicker. Less droop is best suited
for high-traction surfaces such as US black carpet, especially when traction rolling is an issue (and
particularly when a rear solid axle is used).
FRONT DROOP
Front droop is adjusted by the preload of the front spring.
More shims between the steering block and the spring will
increase preload - and decrease droop. Removing shims will
have the opposite effect.

FRONT DAMPING with different oils.
TRACK CONDITIONS
Thinner oil is recommended for low-traction
tracks, while thicker oil is recommended for
high-traction tracks.
DAMPING
Using thicker oil on the king pin axle makes
the car less responsive but easier to drive.
Thicker oil oil also increases stability but
decreases cornering speed.
LOW traction & bumpy track
7K ~ 10K cSt
HIGH traction & smooth track
15K ~ 30K cSt
OIL
The thickness of the shims used
affects the ride height and
droop of the front suspension, so
determine the proper amount
of shims based on tire diameter
and desired droop.
RIDE HEIGHT AND DROOP ADJUSTMENT SHIMS:
The ride height is adjusted with the supplied long shims that can
be fitted under the arms (silver/black/gold). I recommend using
as low of a ride height as you possibly can, unless you race on a
bumpy or rough surface, then the car can benefit from having a
slightly higher ride height, to increase stability, and improve the
handling over bumps.
The front axle height can be adjusted with shims under the
steering block. You can‘t change the roll center on the front end
of the X12, simply because there is no upper arm. Adding shims
under the steering block (raising the steering block) will raise the
front axle height, and at the same time, decrease bump steer.
Removing shims will lower the steering block, and increase bump
steer. For more information about Ackermann & Bumpsteer, see
PAGE 27 (servo mounting).
I recommend using the kit shimming for the front steering block -
this will be a good basic setting for most conditions.
