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.

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.

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
on the king pin; it is important that the
steering block moves freely but without
excessive play. If the king pin 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. Fewer shims will
decrease preload and increase droop.

of shims based on tire diameter
and desired droop.
RIDE HEIGHT AND DROOP ADJUSTMENT SHIMS:
Ride height is adjusted with the supplied long shims (silver, black,
gold) that can be placed under the arms. I recommend using
the lowest possible ride height, unless the track surface is very
bumpy or rough. In that case, the car can benefit from having a
slightly higher ride height which will help to increase stability and
improve handling over bumps.
The front axle height can be adjusted with shims under the
steering block. You cannot change the roll center at the front
of the X10’22 because there is no upper arm. Adding shims
under the steering block – which raises the steering block – will
raise the front axle height, and at the same time will decrease
bump steer. Removing shims will lower the steering block and
increase bump steer. For more information about Ackermann &
Bumpsteer, see PAGE 23 (servo mounting).
I recommend using the kit shimming for the front steering block
as a good basic setting for most conditions.

ROLL CENTER ADJUSTMENT
The roll center can be adjusted by adding or
removing shims from beneath the aluminum pivot
mounts.
LOWER ROLL CENTER
(INITIAL SETTING - NO SHIMS) will give more
traction and increase chassis roll.
HIGHER ROLL CENTER
(adding shims) will increase steering by making
the car rotate more on-and off-power
IMPORTANT! Always use same shim thickness on
both sides of BOTH aluminum holders
Do not use shims for

REARWARD: (INITIAL SETTING)
Pivot mounted in rearward chassis holes, and 1mm shim used under the pivot ball.
The rearward pivot mounting position gives the most steering and most free rear end.
Recommended for high-traction conditions such as US black carpet.
FORWARD:
Pivot mounted in forward chassis holes, with 3mm shims under the pivot ball. The
forward pivot mounting position gives a good balance between front and rear traction.
Ensure free,
smooth movement
Tighten the screw enough
to remove excess play, while
ensuring that the pod plate can

To set track-width, use the hole in the pod lower plate as the centre point; this hole should
always be centred between the two rear wheels once overall track-width is set. To set the
track-width more easily, set the car on a ruler or use a digital vernier caliper.
Rear track-width is directly affected by wheel offsets, which can vary depending on tire brand.
