may result in property damage and serious injury. The
precautions outlined in this manual should be strictly
followed to help ensure safe operation. You alone must
see that the instructions are followed and the precautions
are adhered to.
Important Points to Remember
• Your model is not intended for use on public roads or
congested areas where its operation can conict with or
disrupt pedestrian or vehicular trafc.
• Never, under any circumstances, operate the model in
crowds of people. Your model is fast and could cause
injury if allowed to collide with anyone.
• Because your model is controlled by radio, it is subject
to radio interference from many sources that are
beyond your control. Since radio interference can cause
momentary losses of radio control, always allow a safety
margin in all directions around the model in order to
prevent collisions.
• The motor and battery can become hot during use.
Be careful to avoid getting burned.
• Don’t operate your model at night, or anytime your line
of sight to the model may be obstructed or impaired in
any way.
• Most importantly, use good common sense at all times.
Speed Control
• Disconnect the Battery: Always disconnect the battery
from the model when not in use.
• Transmitter on First: Switch on your transmitter rst
before switching on the speed control to prevent
runaways and erratic performance.
• Don’t Get Burned: The motor can become extremely hot
during use, so be careful not to touch it until it is cool.
Make sure there is adequate airow to the motor.
• Use the Factory-Installed Connectors: Do not change
the battery connector. Improper wiring can cause re or
damage to the ESC. Please note that modied speed
controls can be subject to a rewiring fee when returned
for service.
• Insulate the Wires: Always insulate exposed or damaged
wiring with heat shrink tubing to prevent short circuits.
• No Reverse Voltage: The speed control is not protected
against reverse polarity voltage. When changing the
battery, be sure to install the same type of connectors
to avoid reverse polarity damage to the speed control.
Removing the battery connectors on the speed control
or using the same-gender connectors on the speed
control will void the product’s warranty.
• No Schottky Diodes: External Schottky diodes are
not compatible with reversing speed controls. Using a
Schottky diode will damage the ESC and void the 30-
day warranty.

tab and sliding the door open.
2. Install the batteries in the correct orientation, as
indicated in the battery compartment.
3. Reinstall the battery compartment door and snap it
closed.
4. Turn on the transmitter and check the status LED for a
solid green light.
If the status LED ashes red, the transmitter batteries may
be weak, discharged, or possibly installed incorrectly.
Replace with new or freshly charged batteries. The status
LED does not indicate the charge level of the battery
pack installed in the model. Refer to the Troubleshooting
section on page 11 for more information on the transmitter
status LED codes.
If the status LED doesn’t light green on the
transmitter, check the polarity of the batteries.
Check rechargeable batteries for a full charge. If you see
any other ashing signal from the LED, refer to the chart
on page 11 to identify the code.
CHARGING THE BATTERY PACK
Your model includes a
12-volt DC charger that
will charge the supplied
battery in about 35 minutes.
Plug the charger into an
automotive auxiliary power
socket. The charger is
compatible with 12-volt
automotive auxiliary power
sockets only. The LED
on the charger will glow
red. Plug the battery into
the charger. The LED will
blink green, indicating the
battery is charging. When
charging is complete
(indicated by a solid green
LED), unplug the battery
from the charger, and
unplug the charger from
the power socket. Never leave a battery unattended
while charging.
INSTALLING THE BATTERY PACK

THE 2.4GHz RADIO SYSTEM
THE 2.4GHz RADIO SYSTEM
Your model includes a 2.4GHz transmitter. When powered
on, the transmitter will automatically locate and lock onto an
available frequency, allowing multiple models to be raced
together without frequency conicts. The included radio
system has been programmed for your model at the factory
and does not require adjustment, but it does have settings
you may need to access to maintain proper operation of
your model. The detailed instructions (page 9) included
in this manual will help you understand and operate the
functions of the radio system. For additional information and
how-to videos, visit LaTrax.com.
RADIO AND POWER
SYSTEM TERMINOLOGY
Please take a moment to familiarize yourself with these
radio and power system terms. They will be used
throughout this manual.
2.4GHz Spread Spectrum – This model is equipped with
the latest R/C technology. Unlike AM and FM systems
that require frequency crystals and are prone to frequency
conicts, the 2.4GHz radio system automatically selects
and locks onto an open frequency, offering superior
resistance to interference and “glitching.”
BEC (Battery Eliminator Circuit) - The BEC can either
be in the receiver or in the ESC. This circuit allows the
receiver and servos to be powered by the main battery
pack in an electric model. This eliminates the need to
carry a separate pack of 4 AA batteries to power the radio
equipment.
Current - Current is a measure of power ow through the
electronics, usually measured in amps. If you look at wire
like a garden hose, current is a measure of how much
water is owing through the hose.
Electronic Speed Control (ESC) - An electronic speed
control is the electronic motor control inside the model.
ESCs use power more efciently than mechanical speed
controls so that the battery runs longer. An ESC also has
circuitry that prevents loss of steering and throttle control
as the battery loses its charge.
Frequency band - The radio frequency used by the
transmitter to send signals to your model. This model
operates on the 2.4GHz direct-sequence spread
spectrum.
mAh – Abbreviation for milliamp hour, a measure of the
capacity of the battery pack. The higher the number, the
longer the battery will last between recharges.
Neutral position - The standing position that the servos
seek when the transmitter controls are at the neutral
setting.
NiMH - Abbreviation for nickel-metal hydride.
Rechargeable NiMH batteries offer high current handling
and much greater resistance to the “memory” effect.
NiMH batteries generally allow higher capacity than
NiCad batteries. They can last up to 500 charge cycles. A
peak charger designed for NiMH batteries is required for
optimal performance.
Receiver - The radio unit inside your model that receives
signals from the transmitter and relays them to the servos.
Resistance - In an electrical sense, resistance is a
measure of how an object resists or obstructs the ow
of current through it. When ow is constricted, energy
is converted to heat and is lost. The power system is
optimized to reduce electrical resistance and the resulting
power-robbing heat.
Servo - Small motor unit in your model that operates the
steering mechanism.
Transmitter - The hand-held radio unit that sends throttle
and steering instructions to your model.
Trim - The ne-tuning adjustment of the neutral position
of the servos, made by adjusting the steering trim knob on
the face of the transmitter.
Thermal Shutdown Protection - Temperature sensing
electronics used in the ESC detect overloading and
overheating of the transistor circuitry. If excessive
temperature is detected, the unit automatically shuts
down to prevent damage to the electronics.
2-channel radio system - The 2.4GHz radio system,
consisting of the receiver, the transmitter, and the servos.
The system uses two channels: one to operate the throttle
and one to operate the steering.
Voltage - Voltage is a measure of the electrical potential
difference between two points, such as between the
positive battery terminal and ground. Using the analogy
of the garden hose, while current is the quantity of water
ow in the hose, voltage corresponds to the pressure that
is forcing the water through the hose.

RADIO SYSTEM RULES
• The 2.4GHz transmitter has a directional antenna.
For maximum range, hold the transmitter upright and
pointed in the direction of the model. Pointing the
transmitter away from the model will reduce radio range.
• Always turn your transmitter on rst and off last. This
procedure will help to prevent your model from receiving
stray signals from another transmitter, or other source,
and running out of control. Your model has electronic
failsafes to prevent this type of malfunction, but the rst,
best defense against a runaway model is to always turn
the transmitter on rst and off last.
• Always use new or freshly charged batteries for the
radio system. Weak batteries will limit the radio signal
between the receiver and the transmitter. Loss of the
radio signal can cause you to lose control of your model.
• In order for the transmitter and receiver to bind to one
another, the receiver in the model must be turned on
within 20 seconds of turning on the transmitter. The
transmitter LED will ash fast red, indicating a failure to
link. If you miss it, simply turn off the transmitter and
start over.
• DO NOT CUT any part of the receiver’s antenna wire.
Cutting the antenna will reduce range.

When rechargeable batteries begin to lose their
charge, they will fade much faster than alkaline dry
cells. Stop immediately at the rst sign of weak batteries.
Never turn the transmitter off when the battery pack is
plugged in. The model could run out of control.
Always turn your
transmitter on rst. Plug in the battery. Turn on the model.

RADIO SYSTEM CONTROLS
Using Reverse: While driving, push the throttle
trigger forward to apply brakes. Once stopped,
return the throttle trigger to neutral. Push the throttle
trigger forward again to engage proportional reverse.
USING THE RADIO SYSTEM
The 2.4GHz Radio System has been adjusted at the
factory for correct operation with your model. The
adjustment should be checked before running the model,
in case of movement during shipping. Here’s how:
1. Turn the transmitter switch on. The status LED on the
transmitter should be solid green (not ashing).
2. Elevate the model on a block or a stand so that all the
tires are off the ground. Make sure your hands are clear
of the moving parts of the model.
3. Plug the battery pack connector into the speed control
connector.
4. The on/off switch is integrated into the speed control.
Press and release the EZ-Set button to turn the model
on. The LED will shine RED (see note, below). To turn
the ESC off, press and hold the EZ-Set button until the
LED turns off. Note: If the LED shines green, Low-
Voltage Detection is activated. This may cause poor
performance from the included NiMH battery pack. The
default factory setting is for Low-Voltage Detection to
be disabled (LED shines red). See page 13 for more
information on Low-Voltage Detection.
5. Turn the steering wheel on the transmitter back and
forth and check for rapid operation of the steering
servo. Also, check that the steering mechanism is not
loose or binding. If the steering operates slowly, check
for weak batteries.
6. When looking down at the model, the front wheels
should be pointing straight ahead. If the wheels are
turned slightly to the left or right, slowly adjust the
steering trim control on the transmitter until they are
pointing straight ahead.
7. Gently operate the throttle trigger to ensure that you
have forward and reverse operation, and that the motor
stops when the throttle trigger is at neutral.
8. Once adjustments are made, turn off the receiver on
your model, followed by the hand-held transmitter.
Range-Testing the Radio System
Before each running session with your model, you should
range-test your radio system to ensure that it operates
properly.
1. Turn on the radio system and check its operation, as
described in the previous section.
2. Have a friend hold the model. Make sure hands and
clothing are clear of the wheels and other moving parts
on the model.
3. Walk away from the model with the transmitter until
you reach the farthest distance you plan to operate the
model.
4. Operate the controls on the transmitter once again to
be sure that the model responds correctly.
5. Do not attempt to operate the model if there is
any problem with the radio system or any external
interference with your radio signal at your location.
Higher Speeds Require Greater Distance
The faster you drive your model, the more quickly it will
near the limit of radio range. At top speed, this model can
cover up to 40 feet per second! It’s a thrill, but use caution
to keep your model in range. If you want to see your
model achieve its maximum speed, it is best to position
yourself in the middle of the model’s running area, not
the far end, so you drive the model toward and past your
position. In addition to maximizing the radio’s range, this
technique will keep your model closer to you, making it
easier to see and control.
No matter how fast or far you drive your model,
always leave adequate space between you, the
model, and others. Never drive directly toward
yourself or others.

RADIO SYSTEM BASIC ADJUSTMENTS
Steering Trim
The steering trim knob located on the face of
the transmitter adjusts the neutral (center) point
of the steering channel. If your model pulls to the right or
left when the steering wheel is centered, turn the knob
until the model drives straight when the steering wheel is
centered.
Channel Reversing
The 2.4GHz transmitter has been programmed with
the correct servo direction settings for your model and
should not require adjustment. These instructions are for
reference and troubleshooting only.
Reversing a channel reverses the direction of the
corresponding servo. For example, if you turn the steering
wheel to the right and the model turns left, Channel 1
would need to be reversed to correct the servo direction.
Use the following procedures to reverse the steering and
throttle channels, if necessary. Servo reversing should
only be required if you accidentally reset the direction
of a channel. Do not reverse the steering or throttle
channels unless necessary.
Steering reversing procedure:
1. Press and hold the SET button on the transmitter for
two seconds. The status LED will ash green.
2. Turn and hold the steering wheel to the full left or full
right position (it does not matter which position you
choose).
3. While holding the steering wheel in position, press the
SET button to reverse the channel.
4. The channel is now reversed. Conrm correct servo
operation before running your model.
Throttle reversing procedure:
Note: Throttle reversing is often times unnecessary on
electric models, as issues with the throttle can usually
be solved by reprogramming the speed control and/
or verifying that the motor is wired correctly. Before
attempting to reverse the throttle channel using the
procedure below, you should rst recalibrate the speed
control. Refer to “ESC Setup Programming” on page 13.
1. Press and hold the SET button on the transmitter for
two seconds. The status LED will ash green.
2. Move and hold the throttle trigger to the full forward or
full brake position (it does not matter which position you
choose).
3. While holding the throttle trigger in position, press the
SET button to reverse the channel.
4. The channel is now reversed. Recalibrate the speed
control and then conrm correct servo operation before
running your model.
Binding Instructions
For proper operation, the transmitter and receiver must
be electronically “bound”. This has been done for you at
the factory. Should you ever need to re-bind the system
or bind to an additional transmitter or receiver, follow
these instructions. Note: The receiver must be connected
to a 4.8-6.0v (nominal) power source for binding and the
transmitter and receiver must be within 5 feet of each other.
1. Press and hold the SET button on the transmitter.
2. Turn on the transmitter and release the SET button.
The status LED will ash red slowly, indicating that the
transmitter is in bind mode.
3. Press and hold the LINK button on the receiver.
4. Turn on the speed control by pressing the EZ-Set
button, and release the LINK button.
5. When the LEDs on both the transmitter and the receiver
turn solid green, the system is bound and ready for use.
Conrm that the steering and throttle operate properly
before driving your model.
Failsafe
The 2.4GHz radio system is equipped with a built-in
failsafe function that returns the throttle to its last saved
neutral position in the event of a signal loss. The LED on the
transmitter and the receiver will rapidly ash red when the
failsafe mode is activated. If failsafe activates while you are
operating your model, determine the reason for signal loss
and resolve the problem before operating your model again.

to guard against overheating caused by excessive
current ow. If the operating temperature exceeds safe
limits, the ESC will automatically shut down. The LED
on the face of the ESC will rapidly blink red, even if
the throttle trigger is moved back and forth. Once the
temperature returns to a safe level, the ESC will once
again function normally.
ESC Setup Programming
(Calibrating your ESC and transmitter)
Read through all of the programming steps before you
begin. If you get lost during programming or receive
unexpected results, simply unplug the battery, wait a few
seconds, plug the battery back in, and start over.
1. Elevate the model on a block or a stand so that all the
tires are off the ground. This is a precaution to prevent
runaway when the speed control in turned on before it
is programmed.
2. Connect a fully charged battery pack to the ESC.
3. Turn on the transmitter (with the throttle at neutral).
4. Press and hold the EZ-
Set button (A). The LED
will rst turn green and
then red. Release the
button.
5. When the LED blinks
RED ONCE, pull the
throttle trigger to the full
throttle position and hold
it there (B).
6. When the LED blinks RED
TWICE, push the throttle
trigger to the full reverse
and hold it there (C).
7. When the LED blinks GREEN ONCE,
programming is complete. The LED will
then shine red, indicating the ESC is on
and at neutral (D).
ESC Battery Settings (Low-Voltage Detection Setting)
The ESC is equipped with a built-in Low-Voltage Detection
feature that constantly monitors the battery voltage when
activated. This feature is not compatible with the NiMH
battery supplied with your model. Low-Voltage Detection
has been DISABLED for best performance with your battery;
however, you should verify that the setting has not been
changed before each use.
Verify that Low-Voltage Detection is DISABLED:
1. Turn on the transmitter (with the throttle at neutral).
2. Connect a fully charged battery pack to the model.
3. Press and release the EZ-Set button
to turn the ESC on. If the LED is solid
red, then the Low-Voltage Detection
is DISABLED. If the LED is solid
green, then Low-Voltage Detection
is ACTIVATED (not safe for use with
NiMH batteries).
To disable Low-Voltage Detection (NiMH setting):
1. Make sure the LED on the ESC is on and GREEN.
2. Press and hold the EZ-Set button (the LED will turn off).
After ten seconds, the motor will beep three times and
the LED will shine RED. Release the button.
3. Low-Voltage Detection is now DISABLED.

LED Codes and Protection Modes
• Solid Red: ESC power-on light.
• Fast Blinking Red: The ESC is equipped with thermal
shutdown protection to guard against overheating caused by
excessive current ow. If the operating temperature exceeds
safe limits, the ESC will automatically shut down. Let the
ESC cool.
• Slow Blinking Red (with Low-Voltage Detection on):
The ESC has entered Low-Voltage Protection. When the
battery voltage begins to reach the minimum recommended
discharge voltage threshold, the ESC will limit the power
output to 50% throttle. When the battery voltage attempts to
fall below the minimum threshold, the ESC will shut down all
motor output. The LED on the speed control will slowly blink
red, indicating a low-voltage shutdown. The ESC will stay in
this mode until a fully charged battery is connected.
• Fast Blinking Green: The ESC’s LED will blink fast green if
the speed control is not receiving a signal. Make certain the
speed control is properly plugged into the receiver and the
transmitter is switched on.
• Flashing Red and Green: The ESC has entered Over
Voltage Protection. If a battery with too high voltage is used,
the ESC will go into a failsafe mode.

Now it’s time to have some fun! This section contains
instructions on driving and making adjustments to your
model. Before you go on, here are some important
precautions to keep in mind.
• Allow the model to cool for a few minutes between runs.
This is particularly important when using high-capacity
battery packs that allow extended periods of running.
Monitoring temperatures will extend the lives of the
battery and motor.
• Do not continue to operate the model with low batteries
or you could lose control of it. Indications of low battery
power include slow operation and sluggish servos (slow
to return to center). Stop immediately at the rst sign
of weak batteries. When the batteries in the transmitter
become weak, the red power light will begin to ash.
Stop immediately and install new batteries.
• Do not drive the model at night, on public streets, or in
large crowds of people.
• The stock gear combination on each model provides
good overall acceleration and top speed. For 25+mph
top speeds, install the optional high-speed gearing (parts
#7590, 7591, and 7592, sold separately). The optional
high-speed gearing is only intended for high-speed
running on hard surfaces, and is not recommended for
off-road or repetitive starting and stopping or the motor
will be damaged.
•If the model becomes stuck against an object, do not
continue to run the motor. Remove the obstruction
before continuing. Do not push or pull objects with
the model.
• Avoid running your model in tall grass, deep sand,
or other conditions that severely limit the driving
performance of the model. This will strain the power
system and could cause early motor failure.
• Because the model is controlled by radio, it is subject
to radio interference from many sources beyond your
control. Since radio interference can cause momentary
losses of control, allow a safety margin of space in all
directions around the model in order to prevent collisions.
• Use good, common sense whenever you are driving
your model. Intentionally driving in an abusive and rough
manner will only result in poor performance and broken
parts. Take care of your model so that you can enjoy it
for a long time to come.
• High-performance vehicles produce small vibrations that
may loosen hardware over time. Frequently check wheel
bolts and other screws on your vehicle to ensure that all
hardware remains properly tightened.
About Run Time
A large factor affecting run time is the type and condition of
your batteries. The milliamp hour (mAh) rating of the batteries
determines how large their “fuel tank” is. A 2000 mAh battery
pack will theoretically run twice as long as a 1000 mAh pack.
Because of the wide variation in the types of batteries that are
available and the methods with which they can be charged,
it’s impossible to give exact run times for the model. Another
major factor that affects run time is how the model is driven.
Run times may decrease when the model is driven repetitively
from a stop to top-speed and with repetitive hard acceleration.
Tips for Increasing Run Time
• Use batteries with the highest mAh rating you
can purchase.
• Use the included charger or a high-quality
peak-detecting charger.
• Read and follow all maintenance and care instructions
provided by the manufacturer of your batteries and charger.
• Keep the speed control cool.
• Maintain your model. Do not allow dirt or damaged parts
to cause binding in the drivetrain. Keep the motor clean.
mAh Ratings and Power Output
The mAh rating of the battery can affect your top speed
performance. The higher capacity battery packs experience
less voltage drop under heavy load than low mAh rated
packs. The higher voltage potential allows increased speed
until the battery begins to become discharged.
SHOCK MOUNTING POSITIONS
Your model is equipped with adjustable shocks with
variable mounting positions so that you can tune the
suspension. It is designed to handle and perform well
during off-road driving. If you are going to drive on harder
surfaces, move the lower shock to Position 2. The upper
shock position can be adjusted and tuned to nd the best
setup for your driving style.

SHOCK POSITIONS

RUNNING IN WET CONDITIONS
Your model is designed with water-resistant features to
protect the electronics in the model (receiver, servos,
electronic speed control). This gives you the freedom to
have fun driving your model through puddles and other
wet conditions. Though highly water resistant, the model
should not be treated as though it is submersible or 100%
waterproof. Water resistance applies only to the installed
electronic components. Running in wet conditions requires
additional care and maintenance for the mechanical and
electrical components to prevent corrosion of metal parts and
maintain their proper function.
Precautions
• Without proper care, some parts of your model can be
seriously damaged due to contact with water. Know
that additional maintenance procedures will be required
after running in wet conditions in order to maintain the
performance of your model. Do not run your model
in wet conditions if you are not willing to accept the
additional care and maintenance responsibilities.
• Not all batteries can be used in wet environments.
Consult your battery manufacturer to see if their
batteries can be used in wet conditions.
• The LaTrax 2.4GHz transmitter is not water resistant. Do
not subject it to wet conditions such as rain.
• Do NOT operate your model during a rain storm or other
inclement weather where lightning may be present.
• Do NOT allow your model to come in contact with salt
water (ocean water), brackish water (between fresh
water and ocean water), or other contaminated water.
Salt water is highly conductive and highly corrosive. Use
caution if you plan to run your model on or near a beach.
• Even casual water contact can reduce the life of your
motor. Special care must be taken to modify your
driving style in wet conditions to extend the life of the
motor (details below).
Before Running Your Vehicle in Wet Conditions
1.
Consult the section “After Running Your Vehicle in Wet
Conditions” before proceeding. Make sure you understand
the additional maintenance required with wet running.
2. Conrm that your batteries can be used in wet conditions.
Motor Precautions
Motor life can be greatly reduced in water. If the motor
gets excessively wet or submerged, use very light throttle
(run the motor slowly) until the excess water can run out.
Applying full throttle to a motor full of water can cause rapid
motor failure. Your driving habits will determine motor life
with wet motor. Do not submerge the motor under water.
After Running Your Vehicle in Wet Conditions
1. Remove the battery.
2. Rinse excess dirt off the model with low-pressure
water, such as from a garden hose. DO NOT use a
pressure washer or other high-pressure water. Avoid
directing water into the transmission, differentials, etc.
3. Blow off the model with compressed air (optional,
but recommended). Wear safety glasses when using
compressed air.
4. Remove the wheels from the model.
5. Lubricate the drivetrain with thrust bearing grease
(Traxxas Part #2717).
6. Let the model stand or you may blow off with
compressed air. Placing the model in a warm, sunny
spot will aid drying. Trapped water will continue to drip
from the model for a few hours. Place it on a towel or
piece of cardboard to protect the surface underneath.
7. As a precautionary step, remove the rubber plug from
the top of the receiver box and check for trapped water
or dampness. While unlikely, humidity or tiny amounts
of moisture or condensation may enter the receiver
box during wet running. This can cause long-term
problems with the sensitive electronics in the receiver.
If water is present, consider removing the receiver box
during storage to allow the air inside to dry. This step
can improve the long-term reliability of the receiver. To
remove the receiver box, completely loosen the screws
on either side of the box, lift the ESC wire out of the
groove, and then carefully lift the receiver box and
rotate it off to the side. It is not necessary to remove the
receiver or unplug any of the wires.
8. Additional Maintenance: Increase your frequency of
disassembly, inspection, and lubrication of the following
items. This is necessary after extended wet use or if the
vehicle will not be used for an extended period of time
(such as a week or longer). This additional maintenance
is needed to prevent any trapped moisture from
corroding internal steel components.
• Stub axle housing bearings: Remove, clean, and re-oil
the bearings as needed.
•Front and rear differential: Remove, disassemble, clean,
and regrease all the gears in the differential (internal
gears, ring, and pinion). Refer to your exploded view
diagrams for help with disassembly and reassembly.
•Spur and Pinion Gears: Remove, disassemble, and
clean these components. No grease is required on
the spur and pinion gear. Refer to your exploded view
diagrams for help with disassembly and reassembly.
• Motor: Remove the motor, clean with aerosol motor
cleaner, and re-oil the bushings with lightweight
electric motor oil. Be sure to wear eye protection when
using spray aerosol cleaners.
DRIVING YOUR MODEL

MAINTAINING YOUR MODEL
Your model requires timely maintenance in order to stay in
top running condition. The following procedures should be
taken very seriously.
Inspect the vehicle for obvious damage or wear.
Look for:
1. Cracked, bent, or damaged parts
2. Check the wheels and steering for binding.
3. Check for leaks and proper operation of the
shock absorbers.
4. Check the wiring for any frayed wires or loose
connections.
5. Check the mounting of the receiver and servo and speed
control.
6. Check the tightness of the wheel hex bolts with
a wrench.
7. Check the operation of the radio system, especially the
condition of the batteries.
8. Check for any loose screws in the chassis structure or
suspension.
9. Inspect the gears for wear, broken teeth, or debris lodged
between the teeth.
10. Check the tightness of all the pivot balls.
Other periodic maintenance:
•Motor: Every 10-15 runs, remove and clean the motor by
wiping away accumulated dirt and debris from around the
motor shaft bushing on the pinion gear side of the motor.
Use a product such as electric motor cleaning spray to
ush dirt out of the motor. After cleaning, lubricate the
bushings at each end of the motor with a drop of light-
weight electric motor oil.
•Chassis: Keep the chassis clean of accumulated dirt and
grime. Periodically inspect the chassis for damage.
•Shocks: Keep the oil level in the shocks full. Use only
100% pure silicone shock oil to prolong the life of the
seals. If you are experiencing leakage around the top of
the shock, inspect the bladder in the top cap for signs of
damage or distortion from overtightening. If the bottom
of the shock is leaking, then it is time for a rebuild. The
Traxxas rebuild kit for two shocks is part #7662.
•Suspension: Periodically inspect the model for signs
of damage such as bent or dirty suspension pins, bent
camber links, loose screws, and any signs of stress or
bending. Replace components as needed.
•Driveline: Inspect the driveline for signs of wear such as
worn drive yokes, dirty axle driveshafts, and any unusual
noise or binding. Remove the gear cover, inspect the
spur gear for wear, and check the tightness of the set
screw in the pinion gear. Tighten, clean, or replace
components as needed.
