SAFETY PRECAUTIONS
All of us at Traxxas want you to safely enjoy your new model. Operate
your model sensibly and with care, and it will be exciting, safe, and
fun for you and those around you. Failure to operate your model in
a safe and responsible manner 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 conflict with or disrupt pedestrian or vehicular traffic.
• Never, under any circumstances, operate the model in crowds of people. Your
model is very 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, battery, and speed control 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
Your XL-5 is an extremely powerful electronic device capable of delivering high
current. Please closely follow these precautions to prevent damage to the speed
control or other components.
• 15-Turn Motor Limit: The XL-5 has a 15-turn modified motor limit for 540 size
motors and a 12-turn modified motor limit for 550 size motors with 0 timing
when the motor is properly geared. If the motor or speed control is overheating,
try a smaller pinion gear. Do not attempt to use a more powerful motor (fewer
turns) than the above-mentioned motor limits or you could experience frequent
thermal shutdown.
• Insulate the Wires: Always insulate exposed wiring with heat shrink tubing to
prevent short circuits.
• Transmitter on First: Switch on your transmitter first before switching
on the speed control to prevent runaways and erratic performance.
• Use Neutrally Timed Motors: For reverse use, the motors must have 0° timing.
Modified motors (with adjustable end bells) timed to 0° or Johnson/ Mabuchi
(closed end bell) motors are recommended. Using motors with other than 0°
timing will draw excess current in reverse, and can result in the speed control
overheating and premature motor wear.
• 4-7 NiMH cells or 2 LiPo cells (2S) Only: The XL-5 can only accept a maximum
input voltage of 8.4 volts (NiMH), 7.4 volts (2S LiPo). Always adhere to the
minimum and maximum limitations of the XL-5 as stated in the specifications
table.

This model is not intended
for use by children under
14 years of age without the
supervision of a responsible
and knowledgeable adult.
All instructions and
precautions outlined in this
manual should be strictly
followed to ensure safe
operation of your model.
No previous experience
with radio controlled
models is required.
Models require a minimum
of setup, maintenance, or
support equipment.
• Use Stock Connectors: If you decide to change the battery or motor connectors,
only change one battery or motor connector at a time. This will prevent
accidentally mis-wiring the speed control. If the XL-5 is not wired exactly as
shown in the diagram, it can be damaged! Please note that modified speed
controls can be subject to a rewiring fee when returned for service.
• No Reverse Voltage: The speed control is not protected against
reverse polarity voltage. When changing the battery and/or motor, 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.
• Motor Capacitors Required: Three 0.1µF (50V) ceramic capacitors should be
properly installed on every motor to prevent radio interference. Capacitors have
been provided with the XL-5.
• No Schottky Diodes: External schottky diodes are not compatible with reversing
speed controls. Using a schottky diode with the XL-5 will damage the ESC and
void the 30-day warranty.
Batteries and Battery Charging
The XL-5 speed control uses rechargeable batteries that must be handled with care
for safety and long battery life. Make sure to read and follow all instructions and
precautions that were provided with your battery packs and your charger. It is your
responsibility to charge and care for your battery packs properly. In addition to
your battery and charger instructions, here are some more tips to keep in mind.
• Never leave batteries to charge unattended.
• Remove the batteries from the model while charging.
• Allow the battery packs to cool off between runs (before charging).
• Always unplug the battery from the electronic speed control when the model is
not in use and when it is being stored or transported.
• Do not use battery packs that have been damaged in any way.
• Do not use battery packs that have damaged wiring, exposed wiring, or a
damaged connector.
• Children should have responsible adult supervision when charging and handling
batteries.
• Use the supplied charger to charge the included battery. See “Charging theBattery
Pack” on page 11.
• Do not charge batteries inside of an automobile. Do not charge batteries while
driving in an automobile. The charger is equipped with a long cord intended
to allow the battery to be charged outside of an automobile when using the
automobile’s auxiliary power socket. If the cord will not reach outside of the
automobile, find another power source.
• Never charge batteries on wood, cloth, carpet or on any other flammable material.
• Do not operate the charger in a cluttered space, or place objects on top of the
charger or battery.
• If a battery gets hot to the touch during the charging process (temperature
greater than 140°F / 60°C), disconnect the battery from the charger and
discontinue charging immediately.
• Always store battery packs safely out of the reach of children and pets.
• Do not short-circuit the battery pack. This may cause burns and severe damage to
the battery pack and create the risk of fire.
• Do not burn or puncture the batteries. Toxic materials could be released. If eye or
skin contact occurs, flush with water.
• Do not expose the charger to water or moisture.
• Do not disassemble the charger.
• Store the battery pack in a dry location, away from heat sources and direct
sunlight.
• Nickel-Metal Hydride (NiMH) batteries must be recycled or disposed of properly.
Recycling Your Traxxas Power Cell NiMH Battery
Traxxas strongly encourages you to recycle your Power Cell NiMH battery when it
has reached the end of its useful life. Do not throw your battery in the trash. All
Power Cell NiMH battery packs display the RBRC (Rechargeable Battery Recycling
Corporation) icon, indicating they are recyclable. To find a recycling center near
you, ask your local hobby dealer or visit www.call2recycle.org.
LiPo Batteries
Lithium Polymer (LiPo) batteries are becoming popular for use in R/C models due
to their compact size, high energy density, and high-current output; however,
these types of batteries require special care and handling procedures for long life
and safe operation. WARNING: LiPo batteries are intended only for advanced
users that are educated on the risks associated with LiPo battery use. Traxxas
does not recommend that anyone under the age of 14 use or handle LiPo
battery packs without the supervision of a knowledgeable and responsible
adult.
The XL-5 speed control is able to use LiPo batteries with nominal voltage not to
exceed 7.4 volts (2S packs). LiPo batteries have a minimum safe discharge voltage
threshold that should not be exceeded. The XL-5 is equipped with built-in Low-
Voltage Detection that alerts the driver when LiPo batteries have reached their
minimum voltage (discharge) threshold. It is the driver’s responsibility to stop
immediately to prevent the battery pack from being discharged below its safe
minimum threshold.
Low-Voltage Detection on the speed control is just one part of a comprehensive
plan for safe LiPo battery use. It is critical for you, the user, to follow all
other instructions supplied by the battery manufacturer and the charger
manufacturer for proper charging, use, and storage of LiPo batteries. Make sure
you understand how to use your LiPo batteries. Be aware that Traxxas shall not
be liable for any special, indirect, incidental, or consequential damages arising out
of the installation and/or use of LiPo batteries in Traxxas products.
DO NOT ATTEMPT TO CHARGE LIPO BATTERIES OR ANY OTHER TYPE OF BATTERY
WITH THE INCLUDED TRAXXAS CHARGER.
If you have questions about LiPo battery usage, please consult with your local
hobby dealer or contact the battery manufacturer.

INSTALLING THE BATTERY PACK
Install the battery pack with
the battery wires facing the
rear of the model. Insert the
tabs of the battery hold-down
into the slots in the rear hold-
down retainer and then place
the battery hold-down over
the post. Secure the battery
hold-down with a body clip in
the hole in the post. Do not
connect the battery pack yet.
Using a Different Battery Configuration
The battery hold-down is capable of accommodating side-by-side
racing style packs, “hump packs” with a stacked seventh cell, or the
more common stick packs. The battery compartment is configured
for stick packs from the factory. The number on each side of the
hold-down indicates the battery height in millimeters that hold-
down can accommodate. Note that one side is labeled “25” and
the other side is labeled “23”. The 25mm side is for use with typical
stick type battery packs. If you are using side-by-side racing packs,
simply flip the hold-down over to the 23mm side and use it on the
opposite side of the chassis. Note: For taller batteries, an extended
battery hold-down, part #6727X, is available (sold separately). For
shorter batteries (6-cell), use the included foam block in the front of
the battery compartment.
The Traxxas High-Current Connector
Your model is equipped with the Traxxas High-

TRAXXAS TQ 2.4GHz RADIO SYSTEM
INTRODUCTION
Your model includes the TQ 2.4GHz transmitter. When powered on, the
TQ 2.4GHz will automatically locate and lock onto an available frequency,
allowing multiple models to be raced together without frequency
conflicts. Just switch on and drive! The included TQ 2.4GHz 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
11) included in this manual will help you understand and operate the
functions of the new TQ 2.4GHz radio system. For additional information
and how-to videos, visit Traxxas.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.
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 flow through the electronics,
usually measured in amps. If you think of a wire as a garden hose,
current is a measure of how much water is flowing through the hose.
ESC (Electronic Speed Control) - An electronic speed control is the
electronic motor control inside the model. The XL-5 uses MOSFET
power transistors to provide precise, digital proportional throttle
control. Electronic speed controls use power more efficiently than
mechanical speed controls so that the batteries run longer. An
electronic speed control also has circuitry that prevents loss of steering
and throttle control as the batteries lose their 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
.
LiPo - Abbreviation for Lithium Polymer. Rechargeable LiPo battery
packs are known for their special chemistry, which allows extremely
high energy density and current handling in a compact size. These are
high-performance batteries that require special care and handling. For
advanced users only.
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.
NiCad - Abbreviation for nickel-cadmium. The original rechargeable
hobby pack, NiCad batteries have very high
current handling, high
capacity, and can last up to 1000 charging cycles. Good charging
procedures are required to reduce the possibility of developing a
“memory” effect and shortened run times.
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 flow of current through it. When flow is
constricted, energy is converted to heat and is lost.
Servos - Small motor units in your model that operate the steering and
throttle mechanisms.
Transmitter - The hand-held radio unit that sends throttle and steering
instructions to your model.
Trim - The fine-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 are
used in the ESC to 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 TQ 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.
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 conflicts, the TQ 2.4GHz system automatically
selects and locks onto an open frequency, and offers superior resistance to
interference and “glitching.”
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 flow in the hose, voltage corresponds to the pressure
that is forcing the water through the hose.
550 and 540 - These numbers refer to the size of the motor. 550 motors
have armatures that are 30% longer than 540 motors.
Applying the Decals
The main decals for your
model have been applied at
the factory. Additional decals
have been printed on self-
adhesive clear mylar and are
die-cut for easy removal. Use
a hobby knife to lift the corner
of a decal and lift it from the
backing.
To apply the decals, place one
end down, hold the other end
up, and gradually smooth the
decal down with your finger
as you go. This will prevent air
bubbles. Placing both ends
of the decal down and then
trying to smooth it out will
result in air pockets. Look
at the photos on the box for
typical decal placement.

TRAXXAS TQ 2.4GHz RADIO SYSTEM
RADIO SYSTEM RULES
• Always turn your transmitter on first 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 first, best defense against a runaway model
is to always turn the transmitter on first 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 flash fast
red, indicating a failure to link. If you miss it, simply turn off the
transmitter and start over.
• Always turn on the transmitter before plugging in the battery.
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 TQ 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 flash green.

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 first recalibrate the speed
control. Refer to “XL-5 Setup Programming” on page 14.
1. Press and hold the SET button on the transmitter for two seconds.
The status LED will flash 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 confirm correct servo operation before running
your model.
USING THE RADIO SYSTEM
The TQ 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 flashing).
2. Elevate the model so that the rear tires are off the ground.
If you are holding the model, grip it firmly. Make sure your hands
are clear of the moving parts of the model.
3. Plug the battery pack in the model into the speed control.
4. Press and release the EZ-Set button on the speed control to turn
the model on. The speed control’s LED will glow red. To turn the
speed control off, press the EZ-Set button until the LED turns off.
Note: If the LED shines green after the speed control is turned
on, Low-Voltage Detection is activated. This may cause poor
performance from NiMH battery packs. Make sure to turn the
Low-Voltage Detection on when using LiPo batteries. Never use
LiPo batteries while Low-Voltage Detection is turned off. See
page 14 for more information.
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. Operate the throttle trigger to ensure that you have full forward
and reverse operation, and that the motor stops when the
throttle trigger is at neutral.
8. Once adjustments are made, turn off 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.
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.
The TQ 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.

STAMPEDE 4X4 • 13
TRAXXAS TQ 2.4GHz RADIO SYSTEM
Higher Speeds Require Greater Distance
The faster you drive your model, the more quickly it will near the
limit of radio range. At top speeds, models can cover anywhere
between 25 to 100 feet every 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
truck’s running area, not the far end, so you drive the truck towards
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.
Your model’s radio system is designed to operate reliably up to the
approximate distance that it is no longer easy or comfortable to see
and control the model. Most drivers will struggle to see and drive
their model at distances farther than a football field (300+ feet). At
greater distances, you could lose sight of your model and you may
also exceed the radio system’s operating range which will cause
the Failsafe system to activate. For best visibility and control of your
model keep your model within 200 feet, regardless of the maximum
range available.
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.
TQ 2.4GHz 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 flash 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. Confirm that the
steering and throttle operate properly before driving your model.

ADJUSTING THE ELECTRONIC SPEED CONTROL
XL-5 Battery Settings (Low-Voltage Detection Setting)
The XL-5 electronic speed control is equipped with built-in Low-
Voltage Detection. The Low-Voltage Detection circuitry constantly
monitors the battery voltage. When the battery voltage begins to
reach the minimum recommended discharge voltage threshold
for LiPo battery packs, the XL-5 will limit the power output to
50% throttle. When the battery voltage attempts to fall below the
minimum threshold, the XL-5 will shut down all motor output.
The LED on the speed control will slowly blink red, indicating a
low-voltage shutdown. The XL-5 will stay in this mode until a fully
charged battery is connected.
Your model includes a Power Cell NiMH battery. The XL-5 speed
control’s Low-Voltage Detection has been disabled for best
performance with this battery. The speed control’s LED will glow
red when it is turned on, indicating Low-Voltage Detection is
disabled. Be certain to activate Low-Voltage Detection if you install
LiPo batteries in your model. Never use LiPo batteries while Low-
Voltage Detection is disabled.
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 XL-5.
3. Press and release the EZ-Set button to turn the XL-5 on. If the LED
is solid red, then the Low-Voltage Detection is DISABLED (not safe
to use LiPo batteries). If the LED is solid green, then Low-Voltage
Detection is ACTIVATED.
To activate Low-Voltage Detection (LiPo setting):
1. Make sure the LED on the XL-5 is on and RED.
2. Press and hold the EZ-Set button (the
LED will turn off). After ten seconds, the
motor will beep twice and the LED will
shine GREEN. Release the button.
3. Low-Voltage Detection is now ACTIVATED.
To disable Low-Voltage Detection (NiMH setting):
1. Make sure the LED on the XL-5 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.
XL-5 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 pack in, and
start over.
1. Disconnect one of the motor wires between the
XL-5 and the motor. This is a precaution to prevent
runaway when the speed control is turned on
before it is programmed.
2. Connect a fully charged battery pack
to the XL-5.
3. Turn on the transmitter (with the
throttle at neutral).
4. Press and hold the EZ-Set button (A).
The LED will first 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 green or red
(depending on Low-Voltage Detection setting),
indicating the XL-5 is on and at neutral (D).

DRIVING YOUR MODEL
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 (2400mAh and above) battery packs
that allow extended periods of running. Monitoring temperatures will
extend the lives of the batteries 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 first sign
of weak batteries. When the batteries in the transmitter become weak,
the red power light will begin to flash. Stop immediately and install new
batteries.
• Do not drive the model at night, on public streets, or in large crowds of
people.
• 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.
• 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.
• The Titan 12T motor will benefit from a short break-in period to ensure
optimum performance and longer motor life. For the first battery pack, use
the stock installed pinion gear and drive smoothly on a flat, paved surface.
Accelerate smoothly (avoiding full throttle starts), with most of the driving
being done at higher speeds. This will help ensure that the motor provides
the best performance and longest life.
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 3000 mAh battery pack will theoretically run twice as long as
a 1500 mAh sport 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 a high-quality peak-detecting charger.
• Read and follow all maintenance and care instructions provided by the
manufacturer of your batteries.
• Vary your speed. The Titan12T is a fan cooled motor, therefore moderate to
top-speed running helps reduce motor temperatures.
• Maintain your model. Do not allow dirt or damaged parts to cause binding
in the drivetrain. Keep the motor clean and the motor bushings lightly
lubricated.
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.
RUNNING IN WET CONDITIONS
Your new Traxxas 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,
wet grass, snow, and through other wet conditions. Though highly water
resistant, the model should not be treated as though it is submersible or
totally, 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 Traxxas TQ 2.4GHz transmitter is not water resistant. Do not subject it to
wet conditions such as rain.

18 •STAMPEDE 4X4
• 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 gearing and/or your driving style
in wet conditions to extend the life of the motor (details follow).
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. The wheels have small holes molded in to allow air to enter and
exit the tire during normal running. Water will enter these holes
and get trapped inside the tires if holes are not cut in the tires. Cut
two small holes (3mm or 1/8” diameter) in each tire. Each hole
should be near the tire centerline, 180° apart.
3. Confirm that the receiver box O-ring and cover are installed
correctly and secure. Make sure the screws are tight and the blue
O-ring is not visibly protruding from the edge of the cover.
4. Confirm that your batteries can be used in wet conditions.
Motor Precautions
• Titan motor life can be greatly reduced in mud and 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 a wet motor. Do
not submerge the motor under water.
• Do not gear the motor by temperature when running in wet
conditions. The motor will be cooled by water contact and will not
give an accurate indication of appropriate gearing.
After Running Your Vehicle in Wet Conditions
1. Drain the tires by spinning the tires at high speed to “sling” the
water out. One way to do this is to make several high-speed passes
on a flat, dry surface, if possible.
2. Remove the batteries.
3. Rinse excess dirt and mud off the truck with low-pressure water,
such as from a garden hose. Do NOT use pressure washer or other
high-pressure water. Avoid directing water into the bearings,
transmission, etc.
4. Blow off the truck with compressed air (optional, but
recommended). Wear safety glasses when using compressed air.
5. Remove the wheels from the truck.
6. Spray all the bearings, drivetrain, and fasteners with WD-40® or
similar water displacing light oil.
7. Let the truck stand or you may blow off with compressed air.
Placing the truck in a warm, sunny spot will aid drying. Trapped
water and oil will continue to drip from the truck for a few hours.
Place it on a towel or piece of cardboard to protect the surface
underneath.
8. As a precautionary step, remove the sealed receiver box
cover. 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. Removing the receiver box cover during storage
allows the air inside to dry. This step can improve the long-term
reliability of the receiver. It is not necessary to remove the receiver
or unplug any of the wires.
9. 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.
• Spur and pinion gears: Inspect the gears for wear, broken teeth,
or any debris lodged between the teeth. You do not need to
lubricate the gears.
• Titan motor: Remove the motor, clean with aerosol motor
cleaner, and re-oil the bushings with lightweight motor oil. Be
sure to wear eye protection when using spray aerosol cleaners.

The antenna is secured by a 3x4mm
set screw. To remove the antenna
tube, simply remove the set screw
with the included 1.5mm wrench.
When reinstalling the antenna,
first slide the antenna wire into the
bottom of the antenna tube until
the white tip of the antenna is at
the top of the tube under the black
cap. Next insert the antenna tube
into the mount while making sure
that antenna wire is in the slot in
the antenna mount, then install the
set screw next to the antenna tube.
Use the supplied 1.5mm wrench
to tighten the screw just until the
antenna tube is securely in place.
Do not over tighten.
Do not bend or kink the antenna wire! See the
sidebar for more information. Do not shorten the antenna tube.

ADJUSTING YOUR MODEL
Once you become familiar with driving your model, you might need
to make adjustments for better driving performance.
Adjusting Gear Mesh
Incorrect gear mesh is the most
common cause of stripped spur gears.
Gear mesh should be checked and
adjusted anytime a gear is replaced.
Access the gears by removing the
single screw on the gear cover.
To set the gear mesh, loosen the
motor screw. Cut a narrow strip of
notebook paper and run it into the
gear mesh. Slide the motor and pinion
gear into the spur gear. Retighten the
motor screws and then remove the
strip of paper. You should be able to
run a fresh strip of paper through the
gears without binding them.
Adjusting the Toe-in
Geometry and alignment specs play an important role in your
model’s handling. Take the time to set them correctly. Set the
steering trim on your transmitter to neutral. Now, adjust your servo
and tie rods so that both wheels are pointing straight ahead and are
parallel to each other (0° toe-in). This will ensure the same amount
of steering in both directions. For increased stability add 1° to 2°
of toe-in to each front wheel. Use the turnbuckles to adjust the
alignment.
Shock Mounting Positions
Big bumps and rough terrain
require a softer suspension
with the maximum possible
suspension travel and ride
height. Racing on a prepared
track or on-road use requires
a lower ride height and
firmer, more progressive
suspension settings. The
more progressive suspension
settings help reduce body roll
(increased roll stiffness), dive
during braking, and squat
during acceleration.
The suspension of your model has been set up for off-road
performance (position 1 on the front suspension arms and position
2 on the rear suspension arms). If you plan on driving on hard
surfaces, the following changes should be made:
1. Move the front shocks to position 2 on the suspension arms.
2. Move the rear shocks to position 3 on the suspension arms.
3. Add additional preload spacers.
4. Position 1 is not recommended for the rear shocks.
Fine Tuning the Shocks
The four shocks on the model greatly
influence its handling. Whenever you
rebuild your shocks, or make any changes
to the pistons, springs, or oil, always make
changes to them in pairs (front or rear).
Piston selection depends on the range of
oil viscosities that you have available. For
example, using a two-hole piston with a
light-weight oil will, at one point, give you
the same damping as a three-hole piston
with heavier oil.
We recommend using the two-hole pistons
with a range of oil viscosities from 10W to
50W (available from your hobby shop). The
