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.

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

• 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 the
Battery Pack” on page 12.

• 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 Low­Voltage 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.

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 14) 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.

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.

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.

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

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.

Correct

NoNo NoNo

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.

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.

• 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.

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.

SETTING UP THE ANTENNA

The receiver antenna and antenna
tube must be properly installed before
operating your model. Follow these steps
to install the antenna and antenna tube:

1. Slide the antenna wire into the
antenna tube to its full extent. When
fully inserted, the wire should reach
to approximately 1/2 inch below the
tube cap. Do not leave any slack in the
antenna wire.

2. Insert the base of the antenna tube
into the molded post on the chassis.
Take care not to crimp the antenna
wire. Do not bend or kink the antenna
wire! Do not shorten the antenna tube.
See the side bar for more information.

TRAXXAS TQ 2.4GHz RADIO SYSTEM

Make certain the model’s
receiver antenna is properly
installed before operating
your model. See “Installing
the Receiver 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.

RADIO SYSTEM BASIC ADJUSTMENTS

Steering Trim

The steering trim knob located on the face of the
transmitter adjusts the neutral (center) point of the

Neutral

steering channel. If your model pulls to the right or left

when the steering wheel is centered, turn the knob until the model

Brake/Reverse

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

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.

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.

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

6

the transmitter. Loss of the radio signal can cause you to lose

control of your model.

4. The channel is now reversed. Confirm correct servo operation
before running your model.

Throttle reversing procedure:
Note: Throttle reversing is often times unnecessary on electric

models, as issues with the throttle can usually be solved by
reprogramming the speed control and/or verifying that the motor

TRAXXAS TQ 2.4GHz RADIO SYSTEM

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 17.

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 17 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

0°0°

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 range­test 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.

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.

Fail-Safe

Your Traxxas radio system
is equipped with a built­in fail-safe function that
returns the throttle to its
last saved neutral position
in the event of a signal loss.
The LED on the transmitter
and the receiver will rapidly
flash red when the fail­safe mode is activated. If
fail-safe activates while you
are operating your model,
determine the reason for
signal loss and resolve the
problem before operating
your model again.

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.

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 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.

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

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 DISABLED
(factory default) and the LED shines red. If Low-Voltage Detection is
ACTIVATED, the LED will shine green instead of red 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 RED. 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 RED 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 RED.

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 RED.

4. Return the throttle trigger to neutral. The LED will shine RED.

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 RED.

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 red 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.

XL-5 Profile Selection

The speed control is factory set to Sport Mode (100% forward,
brakes, and reverse). To disable reverse (Race Mode) or to allow
50% power (patented Training Mode), follow these steps. The speed

LED Codes and Protection Modes

• Solid Green: XL-5 power-on light. Low-Voltage Detection is
ACTIVATED (LiPo setting).

• Solid Red: XL-5 power-on light. Low-Voltage Detection is
DISABLED (NiMH setting). Never use LiPo batteries while

Low-Voltage Detection is disabled.

• Fast Blinking Red: 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.
Let the XL-5 cool. Make sure your model is properly geared
for the conditions.

• Slow Blinking Red (when Low-Voltage Detection is
activated): The XL-5 has entered Low-Voltage Protection.
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.

• Fast Blinking Green: The XL-5’s LED will blink fast green if
the speed control is not receiving a signal. Make certain the
speed control is properly plugged into the receiver and the
transmitter is switched on.

Throttle Neutral Protection

The XL-5 speed control features
Throttle Neutral Protection,
which prevents the model from
suddenly accelerating if the
speed control is switched on
while the transmitter’s trigger is
being held. When the trigger is
returned to neutral, the XL-5 will
operate properly.

TRAXXAS • 19

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 the supplied optional pinions for top speed running,
limit your driving to paved surfaces only. Running in grass and
off-road could cause excessive loads on the electrical system in the
model.

• 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).

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 RX 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 12T or spur
gear as large as 90T) 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 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 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.

• Transmission: Remove, disassemble, clean, and re-grease the
transmission components. Use a light coating of wheel bearing
grease (from an auto parts store) on the metal gear teeth. Refer
to your exploded view diagrams for help with disassembly and
reassembly.

• 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.

Removing the Receiver

1. Remove the wire clamp by removing the two 2.5x8mm cap screws.

2. Remove the cover by removing the two 3x10mm cap screws.

3. To remove the receiver from the box, simply lift it out and set
to the side. The antenna wire is still inside the clamp area and
cannot be removed yet.

4. Unplug the servo cables from the receiver and remove
the receiver.

Receiver Installation

1. Install the electronic speed control (ESC), servo, and antenna
wiring through the receiver box top (A).

2. Plug the ESC and servo wires into the receiver (see page 11).

3. Bundle wiring as necessary.

4. Make sure the O-ring is properly seated into
the groove in the receiver box bottom so
that the cover will not pinch it or damage it
in any way.

5. Place the receiver box top onto the receiver
box bottom and install and tighten the two
3x10mm cap screws securely.

6. Inspect the cover to make sure that the
O-ring seal is not visible.

7. Arrange the wires neatly using the wire
guides on the receiver box top (B). Excess
ESC and servo wiring should be bundled
inside the receiver box. Pull out all available
antenna wiring from the receiver box.

8. Apply a small bead of silicone grease to the
foam on the wire clamp (C).

9. Install the wire clamp and tighten the two

2.5x8mm cap screws securely (D).

Once you become familiar with driving your model, you might need
to make adjustments for better driving performance

Adjusting the Slipper Clutch

The model is equipped with an
adjustable slipper clutch, which is
built into the large spur gear. The

Tighten

purpose of the slipper clutch
is to regulate the amount
of power sent to the rear
wheels to prevent tire spin.
When it slips, the slipper

Loosen

clutch makes a high-pitch, whining noise. Remove the rubber slipper
clutch plug on the transmission cover in order to adjust the slipper.
Use the 4-way wrench to turn the adjusting nut clockwise to tighten
and counterclockwise to loosen. Place the model on a high-traction
surface, such as carpet. Adjust the slipper so that you can hear it slip
for approximately two feet from a standing, full throttle start. (Learn
more about adjusting the slipper clutch in the sidebar left.)

Adjusting the Toe-in

Geometry and alignment specs play an important roll 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°-2° of toe in to each front wheel. Use
the turnbuckles to adjust the alignment.

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 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. 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.

Wheels and Tires

Many types of aftermarket tires and wheels can be adapted for
use on your model. Most will affect the overall width and the
suspension geometry of the model. The offsets and dimensions
designed into the model’s wheels are intentional; therefore, Traxxas
cannot recommend the use of other non-Traxxas wheels with
different specifications. The diameter of the wheels is an innovative
design, and there is a variety of different tires available for you to
experiment with in addition to the included tires on the model
(listed in your parts list). Experimentation with different types of
tires is recommended to see which ones work the best on the
terrain where the model is run. When selecting tires, consider the
overall diameter and the rubber compound (hard or soft). If the
overall diameter of the tire is significantly increased, you will need
to use a smaller pinion gear to compensate for the larger tire. Soft
compound tires with many short spikes generally work better
on hard, dry surfaces. In loose dirt, a tire with large spikes should
perform better. See your parts list for accessory wheels and tires.

Pre-load

Spacer

To achieve a good starting
point for the slipper clutch
in these models, tighten the
slipper clutch adjusting nut
clockwise until the slipper
clutch adjusting spring
fully collapses (do not over
tighten), and then turn the
slipper clutch nut counter­clockwise one full turn.

Do not run your model with
the slipper clutch adjusting
spring fully compressed. The
minimum recommended
slipper clutch setting is 1/2
turn counterclockwise from
fully compressed.

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 2.72 = 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 the included high-speed gearing (more teeth). If
you want more acceleration and less top speed, use a smaller optional
(not included) pinion gear. The included high-speed gearing is

intended for high-speed running on hard surfaces, and this gearing
is not recommended for off-road or repetitive starting and stopping.

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.

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 rear wheels of the model. Connect a fresh 7.2V battery
pack to the speed control and turn on the ESC (see page 17). The
servo will automatically jump to its center position.

6. Turn off the power to the model followed by the transmitter. The
servo horn is now ready to be installed.

7. Be careful not to move the servo shaft when installing the servo
horn. Readjust the ESC as described in the “Adjusting the Speed
Control” section.

MAINTAINING YOUR MODEL

Your model requires timely maintenance in order to stay in top
running condition. The following procedures should be taken

very seriously.

Inspect the vehicle for obvious damage or wear. Look for:

1. Cracked, bent, or damaged parts

2. Check the wheels and steering for binding.

3. Check the operation of the shock absorbers.

4. Check the wiring for any frayed wires or loose connections.

5. Check the mounting of the receiver and servo(s) 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. The steering servo saver will wear out over time. If the steering
becomes loose, the servo saver should be replaced.

10. Inspect the gears for wear, broken teeth, or debris lodged
between the teeth.

11. Check the tightness of the slipper clutch.

Other periodic maintenance:

• Slipper clutch pads

(friction material):

Under normal use,
the friction material
in the slipper clutch
should wear very slowly.
If the thickness of any one of
the slipper clutch pads is 1.8mm or
less, the friction disc should be replaced.
Measure the pad thickness using calipers or
measuring against the diameter of the 1.5 and 2.0mm hex
wrenches provided with the model.

• Chassis: Keep the chassis clean of accumulated dirt and grime.

Periodically inspect the chassis for damage.

• Steering: Over time, you may notice increased looseness in the
steering system. The servo saver and the tie rod ends will wear
out from use. Replace these components as needed to restore
factory tolerances. See the parts list included with your model for
replacement part numbers.

• Motor: Every 10-15 runs, remove, clean, and lubricate the motor.
Use a product such as electric motor cleaning spray to flush dirt
out of the motor. After cleaning, lubricate the bushings at each
end of the motor with a drop of light-weight electric motor oil.

• 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.

• Suspension: Periodically inspect the model for signs of damage
such as bent or dirty suspension pins, bent turnbuckles, loose
screws, and any signs of stress or bending. Replace components
as needed.

• Driveline: Inspect the driveline for signs of wear such as worn
drive yokes, dirty axle half shafts, and any unusual noise or
binding. If a U-joint pops apart, then it is time to replace the part.
Remove the gear cover. Inspect the spur gear for wear and check
the tightness of the set screws in the pinion gears. Tighten, clean,
or replace components as needed.

Storage

When you are through running the model for the day, blow it off
with compressed air or use a soft bristled paint brush to dust-off
the vehicle.

Always disconnect and remove the battery from the model
whenever the model is stored. If the model will be stored for a long
time, then also remove the batteries from the transmitter.

Always wear eye protection
when using compressed
air or spray cleaners and
lubricants.
