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 – NITRO ENGINES
• Always test the brakes and the throttle before starting your engine to avoid losing
control of the model.
• Make sure the air filter is clean and oiled.
• Never run your engine without an air filter. Your engine can be seriously damaged if
dirt and debris get inside the engine.
2
• For proper engine break-in, please refer to the manual that came with the engine.
• Do not run near open flames or smoke while running your model or while handling
fuel.
• Some parts will be hot after operation. Do not touch the exhaust or the engine until
they have cooled. These parts may reach 275°F during operation!
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.
IMPORTANT NOTES – NITRO FUEL
• Handle fuel only outdoors. Never handle nitro fuel indoors, or mix nitro fuel in a
place where ventilation is bad.
• Only use nitro fuel for R/C models. Do not use gasoline or kerosene in R/C models
as it may cause a fire or explosion, and ruin your engine.
• Nitro fuel is highly inflammable, explosive, and poisonous. Never use fuel indoors
or in places with open fires and sources of heat.
• Always keep the fuel container cap tightly shut.
• Always read the warning label on the fuel container for safety information.
• Nitro-powered model engines emit poisonous vapors and gasses. These vapors irritate
eyes and can be highly dangerous to your health. We recommend wearing rubber or vinyl
gloves to avoid direct contact with nitro fuel.
• Nitro fuel for RC model cars is made of the combination of the methyl alcohol, castor
•
•
•
•
•
•
or synthetic oil, nitro methane etc. The flammability and volatility of these elements is
very high, so be very careful during handling and storage of nitro fuel.
Keep nitro fuel away from open flame, sources of heat, direct sunlight, high
temperatures, or near batteries.
Store fuel in a cool, dry, dark, well-ventilated place, away from heating devices,
open flames, direct sunlight, or batteries. Keep nitro fuel away from children.
Do not leave the fuel in the carburetor or fuel tank when the model is not in use.
There is danger that the fuel may leak out.
Wipe up any spilled fuel with a cloth
Be aware of spilled or leaking fuel. Fuel leaks can cause fires or explosions.
Do not dispose of fuel or empty fuel containers in a fire. There is danger of
explosion.
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.

The engine should be installed on the split mounts as
follows:
➌
STEP 1: Attach lower mounts to chassis.
903310
SFH M3x10
STEP 2: Attach upper mounts to lower mounts.
Adjust gear mesh so there is minimal play
between the gears.
STEP 3: Attach engine to upper mounts.
STEP 4: Loosen lower mount screws, adjust gear mesh,
and then retighten lower mount screws.
Too tight gear mesh will put excessive
strain on all parts and damage the parts.
Too loose gear mesh may result in stripped
gears.
After the gear mesh is initially set, you can remove
the engine AND upper mounts as one assembly by
removing the screws holding the upper mounts to the
lower mounts. When re-installing the engine, you will
not have to re-adjust the gear mesh.

SHOCK FILLING
SHOCK
OIL
➊ Fully extend the piston rod so the piston is at the bottom of the shock body.
➋ Hold the shock upright and slightly overfill the shock body with shock oil.
➌ Let the oil settle and allow air bubbles to rise to the top. Slowly move the piston up and down until
no more air bubbles appear. Add shock oil as necessary.
➍ Pull the piston rod most of the way out of the shock body. Let the shock rest for 5 minutes to allow
the air bubbles to escape.
CUTAWAY VIEW
After you insert the membrane ensure
that it sits properly all around the alu
cup properly.
When installing the shock cap assembly on the shock
body, some oil will leak out... this is normal.
Fully tighten the cap and clean off any excess oil.
After the shock is assembled, the shock rod will push itself
out of the shock body fairly quickly.
Follow the next procedure to adjust the rebound.

After the shock is assembled you have to set the Shock Rebound.
1. To set the Shock Rebound, release the shock composite lower cap.
3. After you have set the Rebound Adjustment, re-install the shock lower composite cap.
2. VERY SLOWLY do the following: Fully pull out the shock rod, push it back in fully, and then fully pull
it out once more. Repeat this procedure the following number of times to achieve the desired Shock
Rebound setting:
10 times - approximately 75% rebound (high rebound - suggested for very low traction track)
15 times - approximately 50% rebound (medium rebound - suggested for standard track)
20 times - approximately 25% rebound (low rebound - suggested for very high traction track)
During the Rebound Adjustment procedure shock oil will leak out of the shock body through the O-ring
on the shock rod... this is normal. During the Rebound Adjustment procedure DO NOT open the upper
shock cap.
4. Check the Shock Rebound setting by pushing the shock rod fully into the shock body, releasing it, and
observing how far the shock rod extends by itself:
* 25% out of the shock body (low rebound)
* 50% out of the shock body (medium rebound)
* 75% out of the shock body (high rebound).
If the shock rod rebounds too much, return to Step 1 and repeat the procedure.
If the shock rod does not rebound enough, you will have to refill the shock with shock oil, and then repeat
the bleeding and Shock Rebound procedure.

Shock length adjustment:
It is VERY important that all shocks are equal length.
Fully extend the shock absorber and measure the end-to-end
length; we recommend using digital calipers to give an accurate
measurement. If a shock absorber is shorter or longer than others,
adjust the shock length by tightening or loosening the ball joint on
the shock rod.
Damping adjustment:
If you built the adjustable shocks, fully extend the shock rod and turn it
slightly to lock the piston in the shock body.
Turning the shock rod fully CCW aligns 4 holes in the pistons (softest
damping). Turning the shock rod fully CW aligns 1 hole in the
pistons (hardest damping). The shocks have four settings, each of
which can be felt by a slight "click".

Do not allow carburetor to close to less than 0.5mm.
Turn on transmitter and receiver and set the throttle servo trim to the neutral
position.
Adjust the idle adjustment screw on the carburetor to open approx. 0.5-1mm.
Adjust both collars on the carb and brake linkages accordingly. The carb
linkage must have approximately 0.5mm of preload on the spring at neutral.
DO NOT ADJUST while the engine is running.

FULL THROTTLE
With the engine NOT RUNNING but the receiver turned ON, apply full throttle at
the transmitter.
Adjust the transmitter‘s throttle servo high-end point so that the servo horn fully
opens the carburetor when the transmitter‘s throttle control (e.g., throttle trigger)
is at 95% of full throttle. The servo should not have excessive strain when at full
throttle, or throttle/carb damage will result.
If the transmitter does not have throttle high-end point adjustment, adjust the
throttle linkage pivot position on the servo horn until full throttle is obtained.

COLLAR
Adjust the composite collar on the brake linkage so the brakes work smoothly.
If the brakes apply too much or not enough, adjust the collar accordingly. If your
