SAFETY PRECAUTIONS
All instructions and
precautions outlined in this
manual should be strictly
followed to ensure safe
operation of your model.
This model is not intended
for use by children under
14 years of age without the
supervision of a responsible
and knowledgeable adult.
No previous experience
with radio controlled
models is required.
Models require a minimum
of setup, maintenance, or
support equipment.
4 • TRAXXAS
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.
• Use the Factory Installed 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.
Recycling Traxxas Power Cell NiMH Batteries
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.
SAFETY PRECAUTIONS
WARNING! CAUTION! DANGER!
FIRE HAZARD! Your model is able to use LiPo
batteries. Charging and discharging batteries has the
potential for fire, explosion, serious injury, and property damage
if not performed per the instructions. Before use, read and follow
all manufacturer’s instructions, warnings, and precautions. In
addition, Lithium Polymer (LiPo) batteries pose a SEVERE risk of
fire if not properly handled per the instructions and require special
care and handling procedures for long life and safe operation. 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. Dispose of used batteries according to the
instructions.
Important Warnings for users of Lithium Polymer (LiPo)
batteries:
• LiPo batteries have a minimum safe discharge voltage threshold
that should not be exceeded. The electronic speed control 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 is just one part of a comprehensive plan
for safe LiPo battery use. It is critical to follow all instructions for
safe and proper charging, use, and storage of LiPo batteries. Make
sure you understand how to use your LiPo batteries. If you have
questions about LiPo battery usage, please consult with your local
hobby dealer or contact the battery manufacturer. As a reminder,
all batteries should be recycled at the end of their useful life.
• ONLY use a Lithium Polymer (LiPo) balance charger with a balance
adapter port to charge LiPo batteries. Never use NiMH or NiCadtype chargers or charge modes to charge LiPo batteries. DO NOT
charge with a NiMH-only charger. The use of a NiMH or NiCad
charger or charge mode will damage the batteries and may cause
fire and personal injury.
• NEVER charge LiPo battery packs in series or parallel. Charging
packs in series or parallel may result in improper charger cell
recognition and an improper charging rate that may lead to
overcharging, cell imbalance, cell damage, and fire.
• ALWAYS inspect your LiPo batteries carefully before
charging. Look for any loose leads or connectors,
damaged wire insulation, damaged cell packaging, impact
damage, fluid leaks, swelling (a sign of internal damage), cell
deformity, missing labels, or any other damage or irregularity.
If any of these conditions are observed, do not charge or use
the battery pack. Follow the disposal instructions included with
your battery to properly and safely dispose of the battery.
• DO NOT store or charge LiPo batteries with or around other
batteries or battery packs of any type, including other LiPos.
• Store and transport your battery pack(s) in a cool dry place.
DO NOT store in direct sunlight. DO NOT allow the storage
temperature to exceed 140°F or 60°C, such as in the trunk of a
car, or the cells may be damaged and create a fire risk.
• DO NOT disassemble LiPo batteries or cells.
• DO NOT attempt to build your own LiPo battery pack from
loose cells.
Charging and handling precautions for all battery types:
• BEFORE you charge, ALWAYS confirm that the charger
settings exactly match the type (chemistry), specification, and
configuration of the battery to be charged.
• DO NOT attempt to charge non-rechargeable batteries (explosion
hazard), batteries that have an internal charge circuit or a
protection circuit, batteries that have been altered from original
manufacturer configuration, or batteries that have missing or
unreadable labels, preventing you from properly identifying the
battery type and specifications.
• DO NOT exceed the maximum manufacturer recommended charge
rate.
• DO NOT let any exposed battery contacts or wires touch each other.
This will cause the battery to short circuit and create the risk of fire.
• While charging or discharging, ALWAYS place the battery (all
types of batteries) in a fire retardant/fire proof container and on
a non-flammable surface such as concrete.
• DO NOT charge batteries inside of an automobile. DO NOT charge
batteries while driving in an automobile.
• NEVER charge batteries on wood, cloth, carpet, or on any other
flammable material.

• ALWAYS charge batteries in a well-ventilated area.
• REMOVE flammable items and combustible materials from the
charging area.
• DO NOT leave the charger and battery unattended while
charging, discharging, or anytime the charger is ON with a battery
connected. If there are any signs of a malfunction or in the event
of an emergency, unplug the charger from the power source and
disconnect the battery from the charger.
• DO NOT operate the charger in a cluttered space, or place objects
on top of the charger or battery.
• If any battery or battery cell is damaged in any way, DO NOT charge,
discharge, or use the battery.
• Keep a Class D fire extinguisher nearby in case of fire.
• DO NOT disassemble, crush, short circuit, or expose the batteries to
flame or other source of ignition. Toxic materials could be released.

INTRODUCTION
Applying the Decals
The main decals for your
model have been applied at
the factory. Additional decals
have been printed on selfadhesive 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.
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 15) included in this
manual will help you understand and operate the functions of the
new TQ 2.4GHz radio system. For additional information and howto 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.
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.

10 • TRAXXAS
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.
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.
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.
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.
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.
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.
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.
TRAXXAS TQ 2.4GHz RADIO SYSTEM
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.
IMPORTANT RADIO SYSTEM PRECAUTIONS
• Do not kink the receiver antenna wire. Kinks in the antenna wire
will reduce range.
• DO NOT CUT any part of the receiver antenna wire. Cutting the
antenna will reduce range.
To prevent loss of radio range,
do not kink or cut the black wire,
do not bend or cut the metal tip,
and do not bend or cut the white
wire at the end of the metal tip.
• You must extend the antenna wire in the model as far as possible
for maximum range. In doing so, the antenna wire will be
extended outside of the vehicle body. Do not wrap or coil the
antenna wire to keep it from extending out of the body.
• The antenna wire must be installed into the antenna tube to
protect it from getting cut or damaged, which will reduce range.
When installing the antenna wire into the antenna tube, be
careful not to kink the wire by pressing it against the antenna
tube cap. The antenna wire should extend to just below or to
within one-half inch below the cap.

If the status LED doesn’t light
green, check the polarity of the
batteries. Check rechargeable
batteries for a full charge. If you
see any other flashing signal from
the LED, refer to the chart on page
17 to identify the code.
Your transmitter uses AA
batteries. Use new alkaline
batteries (Part # 2914) or
rechargeable batteries, such
as NiMH (nickel-metal hydride)
batteries, in your transmitter.
Make sure rechargeable batteries
are fully charged according to
the manufacturer’s instructions.
If you use rechargeable batteries
in your transmitter, be aware that
when they begin to lose their
charge, they lose power more
quickly than regular alkaline
batteries.
Caution: Discontinue running
your model at the first sign of
weak batteries (flashing red light)
to avoid losing control.

To remove the body for chassis access:
1. Pull forward on the front latch while pushing up on the body to release
it from the front body mount.
2. Repeat for the rear latch to release the body from the rear body mount.
3. Lift the body straight up from the chassis.
To reinstall the body on the chassis:
1. Align the pegs on the body posts with the holes in the front and rear
body mounts on the chassis.
2. Press down on the body until the latches snap into place.
The Traxxas High-Current Connector
Your model is equipped with the Traxxas
High-Current Connector. Standard connectors
restrict current flow and are not capable of
delivering the power needed to maximize the
output of the XL-5. The Traxxas connector’s gold-plated terminals
with large contact surfaces ensure positive current flow with the
least amount of resistance. Secure, long-lasting, and easy to grip, the
Traxxas connector is engineered to extract all the power your battery
has to give.
To prevent loss of radio range,
do not kink or cut the black wire,
do not bend or cut the metal tip,
and do not bend or cut the white
wire at the end of the metal tip.

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 fail-safes 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 turn your
transmitter on first.
Plug in the battery.
Turn on the model.
• 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.
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.
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. Confirm correct servo operation
before running your model.
Make certain the model’s
receiver antenna is properly
installed before operating
your model. See “Setting
up the Antenna.” Failure to
properly install the receiver
antenna will result in greatly
reduced radio range and
potential loss of control.
Remember, always turn the
transmitter on first and off
last to avoid damage to your
model.
When rechargeable batteries
begin to lose their charge,
they will fade much faster
than alkaline dry cells. Stop
immediately at the first sign
of weak batteries. Never turn
the transmitter off when the
battery pack is plugged
in. The model could run out
of control.

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.
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 18.
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:
7,8
16 • TRAXXAS
1. Turn the transmitter switch on. The status LED on the transmitter
should be solid green (not flashing).
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 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 18 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. 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. Warning: Do not apply full
throttle in forward or reverse while the model is elevated.
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.
The TQ 2.4GHz transmitter has a directional antenna. For
maximum range, hold the antenna upright and pointed in
the direction of the model. Pointing the transmitter away
from the model will reduce radio range.
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 50 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 fail-safe 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.

XL-5 Battery Settings (Low-Voltage Detection Setting)
The XL-5 electronic speed control is equipped with built-in LowVoltage 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.
When you turn your model on, the XL-5 speed control’s status LED
will glow green, indicating that Low-Voltage Detection is activated
to prevent over-discharging of LiPo batteries. LiPo batteries are
intended only for the most advanced users that are educated on
the risks associated with LiPo battery use.
WARNING: FIRE HAZARD!
Do not use LiPo batteries in this vehicle with
Low-Voltage Detection disabled.
Verify that Low-Voltage Detection is ACTIVATED:
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

ADJUSTING THE ELECTRONIC SPEED CONTROL
XL-5 Operation
To operate the speed control and test the programming, reconnect
the motor wires and place the vehicle on a stable block or stand so
that all of the driven wheels are off the ground.
Note that in steps 1-8 below, Low-Voltage Detection is ACTIVATED
(factory default) and the LED shines green. If Low-Voltage Detection is
DISABLED, the LED will shine red instead of green in steps 1-8 below.
Never use LiPo batteries while Low-Voltage Detection is disabled.
1. With the transmitter on, press and release the EZ-Set button. The
LED will shine GREEN. This turns the XL-5 on. If you press and
release too quickly, you may hear the steering servo jump but
the LED may not stay on. Simply press the button again until the
LED shines GREEN and then release.
2. Apply forward throttle. The LED will turn off until full throttle
power is reached. At full throttle, the LED will shine GREEN.
3. Move the trigger forward to apply the brakes. Note that braking
control is fully proportional. The LED will turn off until full braking
power is reached. At full brakes, the LED will shine GREEN.
4. Return the throttle trigger to neutral. The LED will shine GREEN.
5. Move the throttle trigger forward again to engage reverse
(Profile #1). The LED will turn off. Once full reverse power is
reached, the LED will shine GREEN.
6. To stop, return the throttle trigger to neutral. Note that there is
no programmed delay when changing from reverse to forward.
Use caution to avoid slamming the speed control from reverse
to forward. On high-traction surfaces, this could result in
transmission or driveline damage.
7. To turn the XL-5 off, press and hold the EZ-Set button for 1½
seconds or until the green LED turns off.
8. The XL-5 is equipped with thermal shutdown protection to
guard against overheating caused by excessive current flow.
If the operating temperature exceeds safe limits, the XL-5 will
automatically shut down. The LED on the face of the XL-5 will
rapidly blink red, even if the throttle trigger is moved back and
forth. Once the temperature returns to a safe level, the XL-5 will
once again function normally.

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.
• When using optional pinions for top speed running, limit your
driving to paved surfaces only. Repetitive starting and stopping
and extensive drifting around turns will create excess heat and
overheat the ESC and/or motor. Running in grass and off-road
could also cause excessive loads on the electrical system.
• 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.
• Lower your gear ratio. Installing a smaller pinion gear will lower
your gear ratio, causing less power draw from the motor.
• 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.

DRIVING YOUR MODEL
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.
• 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).
22 • TRAXXAS
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 degrees 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 visible protruding from the edge of the cover.
4. Confirm that your batteries can be used in wet conditions.
5. Use lower gearing (smaller pinion gears, as low as 19T, with
the stock 72-T spur gear) when running in mud, deep puddles,
snow, or other similar situations that will restrict the tires and
put much higher loads on the motor.
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 car 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 car with compressed air (optional, but
recommended). Wear safety glasses when using compressed air.
5. Remove the wheels from the car.
6. Spray all the bearings, drivetrain, and fasteners with WD-40® or
similar water displacing light oil.
DRIVING YOUR MODEL
7. Let the car stand or you may blow off with compressed air.
Placing the car in a warm, sunny spot will aid drying. Trapped
water and oil will continue to drip from the car 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 longterm 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.
• 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.
RECEIVER BOX:
MAINTAINING A WATERTIGHT SEAL
Removing and Installing Radio Gear
The unique design of the receiver box allows the removal and
installation of the receiver without losing the ability to maintain a
watertight seal in the box. The patent-pending wire clamp feature
gives you the ability to also install aftermarket radio systems and
maintain the watertight features of the receiver box.
Receiver Installation
1. Always install the wires into the receiver box before installing the
receiver.
2. Install the antenna wire and the servo
cables into the receiver box.
3. Arrange the wires neatly using the
wire guides in the receiver box. The
excess wire will be bundled inside the
receiver box. Label which wire is for
which channel.
4. Apply a small bead of silicone grease
(Traxxas part #1647) to the wire clamp.
5. Using double-sided adhesive foam
tape, install the receiver into the box.
Note: For best performance, it is recommended that the receiver
be installed in the original orientation as shown.
6. Plug the wires into the receiver. Refer to page 12 for the wiring
diagram.
7. Make sure the box light pipe is aligned
with the receiver LED. Make sure the
O-ring is properly seated into the
groove in the receiver box so that the
cover will not pinch it or damage it in
any way.
8. Install the cover and tighten the three 2.5x10mm socket-head
cap screws securely.
9. Inspect the cover to make sure that the O-ring seal is not visible.
Removing the Receiver
1. To remove the cover, remove the three 2.5x10mm socket-head
cap screws.
2. To remove the receiver from the box, simply lift it out and set to
the side.
3. Unplug the servo cables from the receiver and remove the
receiver.

Adjusting Gear Mesh
Incorrect gear mesh is the most
common cause of stripped spur
gears. Your model includes a fixed
gear positioning system to simplify
the process and ensure proper gear
mesh settings. Access the gears
by removing the four 3x12mm
button-head cap screws from the
gear cover; remove the gear cover.
Remove the motor/motor plate
assembly from the chassis.
To set the gear mesh, use the chart
to the left to identify the screw
positions on the motor plate (A - K)
that correspond with the chosen
motor pinion gear size. Remove the two screws from the motor/
motor plate and reinstall in the corresponding positions; reinstall
the motor/motor plate assembly in the chassis.
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 on-road performance.
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,
Pre-load
using a two-hole piston with a
Spacer
lightweight 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 thinner viscosity oils (30W or less) flow more smoothly and are
more consistent, while thicker oils provide more damping. Use only
100% pure silicone shock oil to prolong seal life. From the factory,
shock oil is set to 50W in the front and rear shocks. The model’s ride
height can be adjusted by adding or removing the clip-on, spring
pre-load spacers. Adjust the ride height so that the suspension arms
are slightly above being parallel to the ground. Observe how the
model handles in turns. Proper set-up will add stability and help
prevent spin outs. Experiment with different springs and shock oils to
find what works best for your current track conditions.
Centering Your Servo
If the trim controls on your transmitter seem off, you may need to
re-center your servo. Additionally, whenever your servo has been
removed for service or cleaning, it must be re-centered prior to
installation in the model.
1. Disconnect the servo horn from the steering servo.
2. Connect the steering servo to channel 1 on the receiver. Connect
the electronic speed control (ESC) to channel 2.
3. Place fresh “AA” batteries in the transmitter and turn the
transmitter power switch on.
4. Turn the steering trim adjustment on the transmitter to the center
“0” position.
5. Elevate the model on a block or stand so that all of the tires are
off the ground. Connect a fresh battery pack to the speed control
and turn on the ESC (see page 18). The servo will automatically
jump to its center position.
ADJUSTING YOUR MODEL
Motors and Gearing
There are two different types of aftermarket motors that can be
purchased for your model, stock and modified. Stock motors all
have the same wire thickness and number of turns around the
armature as governed by sanctioned racing organizations. They
are inexpensive and widely available. Modified motors are more
expensive, may feature ball bearings, and come in a variety of wire
thicknesses and the number of turns of wire on the armature. The
fewer number of turns of wire on the armature, the more powerful
the motor will be. Keep in mind that the more powerful the motor,
the less battery run time you will have.
One of the more significant advantages to your model’s transmission
is the extremely wide range of available gear ratios. It can be geared
low enough to run extremely hot, modified motors. Modified motors
should be geared lower (higher numerically) than stock motors
because they reach their maximum power at higher rpms.
A modified motor that is geared incorrectly can actually be slower
than a correctly-geared, stock motor. Use the following formula to
calculate the overall ratio for combinations not listed on the gear chart:
# Spur Gear Teeth
x 2.85 = Final Gear Ratio
# Pinion Gear Teeth
If you are worried that you might be over-geared, check the
temperature of the battery pack and motor. If the battery is
extremely hot, and/or the motor is too hot to touch, your model is
probably over-geared. If you are not able to run your model for at least
four minutes before the battery dies, then change to a lower gear
ratio. This temperature test assumes that the model is close to factory
stock weight and operates freely with no excessive friction, dragging,
or binding, and the battery is fully charged and in good condition.
The model is equipped with a Titan 12T 550 motor. The gear
combination that comes stock on the model provides good overall
acceleration and top speed. If you want more top speed and less
acceleration, install optional high-speed gearing (more teeth).
If you want more acceleration and less top speed, use a smaller
optional pinion gear (optional gearing not included).
The Titan 12T is equipped with an integrated cooling fan that is
effective during medium to high-speed operation. The gearbox is
specially vented to cool the motor.
Repetitive starting and stopping over short distances creates excess
heat and will not allow the fan to cool the motor properly. For this type
of driving, smaller pinion gears are recommended to reduce load on the
motor. See the guide to the right.
Tuning the Sealed Gear Differentials
The action of the model’s front and rear gear differentials can
be tuned for different driving conditions and performance
requirements, without major disassembly or removal of the
suspension system.
From the factory, the differentials are sealed to maintain consistent
long-term performance. Changing the oil in the differential with
either lower or higher viscosity oil will vary the performance
characteristics of the differentials. Changing to a higher viscosity oil
in the differential will reduce the tendency for motor power to be
transferred to the wheel with the least traction. You may notice this
when making sharp turns on slick surfaces. The unloaded wheels
on the inside of the turn have the least traction and tend to spin
up to extremely high rpms. Higher viscosity (thicker) oil causes the
differential to act like a limited-slip differential, distributing more
equal power to the left and right wheels.
Your model will generally benefit from higher viscosity oil when
racing on low traction surfaces. Note: Heavier oil will allow power to
be transferred even with one or more tires off the ground. This can
make the vehicle more likely to overturn on high-traction surfaces.
From the factory, the front differential is filled with SAE 30,000W
viscosity silicone oil and the rear differential is filled with SAE
10,000W viscosity silicone oil.
Gearing Compatibility Chart:
The chart below shows a full range
of gear combinations acceptable
for this model. This does NOT imply
that these gear combinations
should be used. Over-gearing
(bigger pinions, smaller spurs) can
overheat and damage the motor
and/or speed control.

MAINTAINING YOUR MODEL
Your model requires timely maintenance in order to stay in top
running condition. The following procedures should be taken
very seriously.
Frequently 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 the operation of the shock absorbers.
4. Check the wiring for any frayed wires or loose connections.
5. Check the mounting of the receiver, servo, and speed control.
6. Check the tightness of the wheel nuts 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. Check the operation of the steering servo and ensure that it is not
binding.
10. Inspect the gears for wear, broken teeth, or debris lodged between
the teeth.
• Driveline: Inspect the driveline for signs of wear or any unusual
noise or binding. Remove the gear cover and 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.
Always wear eye protection
when using compressed
air or spray cleaners and
lubricants.
Note: When replacing the
spur gear, be sure the spur
gear is fully seated on the
center driveshaft as shown.
There will be an audible
“click” as the gear is pushed
into place.
Storage
When you are through running your model for the day, blow it off
with compressed air or use a soft bristled paint brush to dustoff the vehicle. Always disconnect and remove the battery from
your model whenever the model is stored. If your model will be
stored for a long time, then also remove the batteries from the
transmitter.
Other periodic maintenance:
• Chassis: Keep the chassis clean of accumulated dirt and grime.
Periodically inspect the chassis for damage.
• 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.
• Steering: Over time, you may notice increased looseness in
the steering system. Replace any components as needed to restore
factory tolerances.
• 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 #2362.
