Safety Precautions
All instructions and
precautions outlined in this
manual should be strictly
followed to ensure safe
operation of your model.
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
This model is not intended
for use by children under
8 years of age without the
supervision of a responsible
and knowledgeable adult.
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.
Batteries and Charging
No previous experience
with radio controlled
models is required.
Models require a minimum
of setup, maintenance, or
support equipment.
Your model 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 backs 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.
Always unplug the battery from the electronic speed control when the model
is not in use and when it is being stored or transported.
Allow the battery packs to cool off between runs (before charging).
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.
Speed Control
General Precautions
Disconnect the Batteries: Always disconnect the battery pack from
the speed control when not in use.
Transmitter on First: Switch on your transmitter first before switching on the
speed control to prevent runaways and erratic performance.
4 • Slash
Don’t Get Burned: The transistor tabs and the heat sinks can get extremely hot,
so be careful not to touch them until they cool. Supply adequate airflow for
Always Use Heat Sinks: Three heat sinks are factory-installed on the speed
control and must be used for maximum cooling and performance.
4 to 8-Cells Only: The XL-5 can only accept a maximum input voltage
of 9.6 volts. Always adhere to the minimum and maximum limitations
of the XL-5 as stated in the specifications table.
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
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 samegender connectors on the speed control will void the product’s warranty.
Do Not Let the Transistor Tabs Touch: Never allow the three separate transistor
banks to touch each other or any exposed metal. This will create a short circuit
and damage the speed control. (For example, laying a metal tool across the
heatsinks can damage the speed control.)
Advanced Precautions
Motor Limit: The XL-5 has a 15-turn modified motor limit for 540 size motor and
a 12-turn modified motor limit for 550 size motor 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.
Use Neutrally Timed Motor: For reverse use, the motor must have 0° timing.
Modified motor (with adjustable end bells) timed to 0° or Johnson/ Mabuchi
(closed end bell) motor are recommended. Using motor with other than 0°
timing will draw excess current in reverse, and can result in the speed control
overheating and premature motor wear.
Motor Capacitors Required: Ceramic capacitors should be properly installed on
every motor to prevent radio interference. These are already installed on the
factory Titan motor.
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

Decorating Your Model
Applying The Decals
Tire Gluing
The main decals for your model have
been applied at the factory. The decals
are printed on self-adhesive clear mylar
and are die-cut for easy removal. Use a
hobby knife to lift the corner of a decal
and lift it from the backing. To apply the
decals, place one end down, hold the
other end up, and gradually smooth the
decal down with your finger as you go.
This will prevent air bubbles. Placing
both ends of the decal down and then
trying to smooth it out will result in air
pockets. Look at the photos on the box
for typical decal placement.
The factory tires on your model are
already glued to the rims. The tires
must be glued to the rims to prevent
the rims from spinning inside the tires.
The instructions here are provided to
show you how to glue replacement
tires to the rims in the future. Use CA
tire glue available from your local
hobby dealer.
1. Remove a wheel from your model using the 4-way wrench.
2. Use your thumb to push the side of the tire away from the rim.
Place one or two drops of CA glue into the opening and release the
tire. Capillary action will draw the glue around the bead of the tire.
3. Repeat step two at four or five points around the rim, until the tire
is completely secured to the rim. Turn the rim over and repeat the
process for the inside of the rim/tire. Repeat for the other three
4. Reinstall the wheels. Make sure none of the axle pins have fallen
out from behind the hex hubs.

Radio and Power System Terminology
Use the Right Charger
The most convenient type
of charger is an AC peakdetecting charger that plugs
directly into an AC wall
outlet. It contains special
peak-detection circuitry
that automatically shuts the
charger off when the battery
is fully charged.
If you’re using a 15-minute
timed charger, always fully
discharge the battery pack
before each charge. Some
high mAh battery packs
(1500 mAh or higher) require
more than the standard 15
minutes of charge time. If
the battery pack is cold after
15 minutes of charging,
add another 5 minutes of
charge time. Closely monitor
the battery pack and stop
charging it when it begins
to feel warm to the touch.
Never leave a battery
charging unattended.
Always follow charger
manufacturer’s instructions.

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.
Channel - The 27 MHz frequency band is divided into 6 channels so that
up to six models can be operated simultaneously. Each channel is
referred to by its flag color and channel number, as shown below.
Part No.
Clearing your frequency - A routine, verbal check to make sure nobody
else in your area is operating on the same channel. Always clear your
frequency by calling out your channel number before operating
your model. Wait or move to another area if your channel is already
being used.
Crystal (X-tal) - The plug-in device that determines which channel the
radio system will operate on. For each channel, there are two crystals,
one for the receiver and one for the transmitter. Of those two crystals,
the one marked with the lower number (.455 MHz lower) must be
inserted into the receiver.
Current - Current is a measure of power flow through the electronics,
usually measured in amps. If you look at wire like a garden hose,
current is a measure of how much water is 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. All Traxxas RTR models operate on a 27 MHz
frequency band.
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
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.
Servo - Small motor unit in your model that operates the steering
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 throttle and steering trim sliders on the face of
the transmitter.
Thermal Shutdown Protection - Temperature sensing electronics
are used in the ESC to detect overloading and overheating of the
transistor circuitry. If excessive temperature is detected, the unit
automatically shuts down to prevent damage to the electronics.
2-channel radio system - The TQ radio system, consisting of
the receiver, the transmitter, and the servos. The system uses
two channels: one to operate the throttle and one to operate
the steering.
Voltage - Voltage is a measure of the electrical potential difference
between two points, such as between the positive battery terminal
and ground. Using the analogy of the garden hose, while current is
the quantity of water flow in the hose, voltage corresponds to the
pressure that is forcing the water through the hose.
The Traxxas TQ Radio System
Installing Transmitter Batteries
Using Different Battery Configuration
The battery hold-downs are capable of accommodating either side-byside racing style packs or the more common stick packs. The battery
compartments are configured for stick packs from the factory. The
number on each side of the hold down indicates the battery height
in millimeters that hold-down can accommodate. Note that one side
is labeled “25” and other side is labeled “23”. The 25mm side is for use
with typical stick type battery packs. If you are using side-by-side racing
packs, simply flip the hold-down over to the 23mm side and use it on the
opposite side of the chassis.
Your TQ transmitter uses 8 AA batteries. The battery compartment is
located in the base of the transmitter.
1.Remove the battery
compartment door by
pressing the tab and
lifting the door up.
2.Install the batteries in
the correct orientation
as indicated in the
battery compartment.
3.Reinstall the battery
door and snap it closed.
4.Turn on the transmitter
and check the power indicator for a solid red light.
If the power indicator light
flashes, then the transmitter
batteries are weak, discharged
or possibly installed incorrectly.
Replace with new or freshly
charged batteries. The power
indicator light does not indicate the charge level of the battery pack
installed in the model.
25mm side: Standard
NiMH stick pack setup
23mm side: Side-by-side
NiMH pack setup
Installing the Battery Pack
Install the battery pack with
the battery wires facing
the rear of the model. Your
model includes a foam
block which should be
installed in front of 6-cell
batteries for a more secure
fit. Remove the foam block
for use with 7-cell “flat”
packs. Insert the tabs of the
battery hold-down into the
Foam Block
slots in the rear hold-down
retainer and then place the
battery hold-down over the
post. Secure the battery hold-down with body clip in the hole in the
post. Do not connect the battery pack yet.
The Traxxas High Current Connector
Your model is equipped with the Traxxas HighCurrent 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 a 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 run this model, your batteries must be equipped with Traxxas
High-Current Connectors. Batteries can either be purchased new with
Traxxas connectors installed or Traxxas connectors can be purchased
to install on battery packs you already own. See sidebar on page 9 for
packages available from your hobby dealer.
The typical Molex style connector is inadequate for
use in your model. It creates resistance that becomes
a bottleneck to current flow. If your battery pack is
equipped with a Molex connector, it must be replaced
with a Traxxas High-Current Connector to mate with
the XL-5 electronic speed control.
Use the Right Batteries
Your transmitter uses AA
batteries. Use new alkaline
batteries, or rechargeable
batteries such as NiCad
or NiMH (Nickel Metal
Hydride) batteries in your
transmitter. Make sure
rechargeable batteries are
fully charged according
to the manufacturer’s
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
Caution: Discontinue
running your model at the
first sign of weak batteries
(flashing red light) to avoid
losing control.
If the power indicator
doesn’t light red, check the
polarity of the batteries.
Check rechargeable
batteries for a full charge.

The Traxxas TQ Radio System
Setting up the Antenna
If there are any kinks in the
black antenna wire, it will
be more difficult to push
through the antenna tube.
Pull the wire straight by
sandwiching it between your
thumb and index finger and
running your fingers along
the length of the wire (with
medium pressure).
Don’t shorten the length of
the antenna wire. Its length
is tuned to the frequency
band; cutting it could
severely shorten the radio
system’s range.
Don’t push the transmitter
antenna down from the
top. Pull it down from the
bottom, one segment at a
time, to prevent binding and
kinking the antenna mast.
1.Remove the antenna tip.
2.Pull the slack wire through the antenna
tube, and then insert the base of the
antenna tube into the antenna post
on the receiver box. Take care not to
crimp the antenna wire.
3. Slide the crimp nut over the antenna
tube and screw it into the antenna
post. Slide the antenna wrench over
the antenna tube and tighten the
crimp nut on the post just until the
antenna tube is securely in place. Do
not over tighten or crush the antenna
wire against the chassis.
4. Fold the top of the antenna wire over
the top of the antenna tube. Slide
the antenna tip onto the top of the
antenna tube. Never cut or shorten
the antenna wire.
5. On the transmitter, always fully
extend the telescoping antenna
when running your model. Make a
habit of holding the transmitter so
the antenna points straight up.
Spray a little window cleaner
on the antenna wire to make
it easier to push through the
antenna tube.
TQ Radio System Controls
You must install the antenna mast
(tube) before you operate your model.
You’ll find the assembled plastic
antenna tube and tip laying in
the chassis.
Crimp Nut
TQ Radio System Adjustments
In addition to the electronic throttle and steering trim controls,
your radio system features throttle neutral adjustment and servo
reversing switches. These are preset at the factory and should not
require further adjustment.
Throttle Neutral Adjustment
The throttle neutral adjustment is located on the transmitter face
and controls the forward/reverse travel of the throttle trigger.
Change the adjustment by pressing the button and sliding it to the
desired position.
12 • Slash
The Traxxas TQ Radio System
There are two settings available:
50/50: Allows equal travel for both
acceleration and reverse.
70/30: Allows more throttle travel (70%)
and less reverse travel (30%).
Note: If you change throttle travel, you
will need to reprogram the electronic
speed control.
Electronic Throttle Trim
The electronic throttle trim located on the face of the transmitter
adjusts the neutral (center) point of the throttle servo when the
servo is at rest. Your model uses an electronic speed control
instead of a throttle servo, this control has been preset for you at
the factory.
Electronic Steering Trim
The electronic steering trim located on the face of the transmitter
adjusts the neutral (center) point of the steering servo when
the servo is at rest. Adjust this control to make the model drive
straight with no steering input at the wheel.
Servo Reversing Switches
The servo reversing switches are located on the front of the
transmitter, next to the on/off switch. Moving a switch reverses
the direction of the corresponding servo.
Each switch corresponds to a channel, as shown below. For
example, if you turn the steering wheel to the right and your
wheels turn left, you would move the Channel 1 switch to
correct the servo direction. It may be necessary to adjust the
corresponding trim control after moving a switch.

TQ Radio System Rules
Remember, always turn the
TQ transmitter on first and
off last to avoid damage to
your model.
Your speed control was
adjusted to the radio from
the factory. It is possible
for the throttle trim control
on the transmitter to have
moved during transit
or while handling the
transmitter. If the motor
runs when the model is
switched on, then move the
throttle trim control on the
transmitter until the motor
stops. If anything more
than a slight adjustment of
the throttle trim control is
required, then you should
readjust your speed control.
Refer to the adjustments
section on page 15.
Channel 1
Each time you prepare to run your model, you
must clear your frequency to be sure no one
else in the area is using the same channel as
you. There are six possible channels, numbered
1 through 6. Each is represented by a color.
Look at the crystal plugged into the back of
your transmitter to determine which channel
your model is assigned to.
Channel 2
Channel 3
Channel 4
Channel 5
Always turn your TQ 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.
Channel 6
Always have the transmitter turned on before plug in
the battery.
Always use new or freshly charged batteries for the radio
system. Weak batteries will limit the range of the radio signal
between the receiver and the transmitter. Loss of the radio
signal can cause you to lose control of your model.
3.Plug the battery pack in the model into the speed control.
4.The on/off switch is integrated into the speed control. With
the transmitter on, press the XL-5 set button for ½ second, until
the LED shines GREEN, then immediately release the button. This
turns the model on (see page 15 for more on XL-5 setup and
operation). To turn the XL-5 off, press the set button until the

Range-Testing the TQ Radio System
Before each running session with your model, you should rangetest your radio system to ensure that it operates properly.
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.
Always turn your
transmitter on first.
Plug in the battery.
Turn on the model.
see TQ Radio System Setup, step 4.
TQ Radio System Setup
The TQ Radio System was pre-adjusted at the factory. The
adjustment should be checked, before running the model,
in case of movement during shipping. Here’s how:
1.Fully extend the chrome antenna mast on the transmitter and
turn the switch on. The red indicator light on the transmitter
should be solid red (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.

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. Make sure your transmitter antenna is fully extended, and then
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.
Adjusting the Electronic Speed Control
XL-5 electronic speed controls are factory set and should not require any
adjustments. These instructions are provided for your reference.
Transmitter Adjustments for the XL-5 ESC
Before attempting to program your XL-5 ESC, it is important to make
sure that your transmitter is properly adjusted (set back to the factory
defaults). Otherwise, you may not get the best performance from your
speed control.
The transmitter should be adjusted as follows:
1. Set the throttle neutral switch to the 50/50 setting.
2. Set the throttle trim to the middle “0” setting. This adjusts the
neutral position.
3. Set the Channel 2 servo reversing switch to the left position.
4. Do not change the position of any of the servo reversing switches
after programming the XL-5 ESC.
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 back in, and start over.
1. Disconnect one of the motor wires between the
XL-5 and the motor. This is a precaution to prevent
runaway when the speed control is turned on before
it is programmed.
2. Connect a fully charged
battery pack to the XL-5.

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. (Note: If the
throttle is not at neutral or if the throttle trim has been altered, the LED
will turn off after one second and the wheels may begin to drive.)
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.

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 insure 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 which 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 topspeed 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 effect your top speed performance. The higher
capacity battery packs experience less voltage drop under heavy load than low
mAh rated packs. The higher voltage potential allows increased speed until the
battery begins to become discharged.
Running in Wet Conditions
Your new Traxxas Slash 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 Slash through puddles, wet grass,
snow, and through other wet conditions. Though highly water resistant, the Slash
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.
• 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. Do not use
LiPo batteries in wet conditions (note: the XL-5 is not LiPo compatible).
• The Traxxas TQ 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).
Slash • 17
Driving your Model
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.
18 • Slash
After Running Your Vehicle in Wet Conditions
1. Drain the tires by spinning the tires at high speed to “sling” the water out. One way
to do this is to make several high-speed passes on a flat, dry surface, if possible.
2. Remove the batteries.
3. Rinse excess dirt and mud off the truck with low-pressure water, such as from a
garden hose. Do NOT use pressure washer or other high-pressure water. Avoid
directing water into the bearings, transmission, etc.
4. Blow off the truck with compressed air (optional, but recommended). Wear
safety glasses when using compressed air.
5. Remove the wheels from the truck.
6. Spray all the bearings, drivetrain, and fasteners with WD-40® or similar water
displacing light oil.
7. Let the truck stand or you may blow off with compressed air. Placing the truck
in a warm sunny spot will aid drying. Trapped water and oil will continue to
drip from the truck for a few hours. Place it on a towel or piece of cardboard to
protect the surface underneath.
8. As a precautionary step, remove the sealed receiver box cover. While unlikely,
humidity or tiny amounts of moisture or condensation may enter the receiver
box during wet running. This can cause long-term problems with the sensitive
electronics in the receiver. Removing the receiver box cover during storage
allows the air inside to dry. This step can improve the long-term reliability of the
receiver. It is not necessary to remove the receiver or unplug any of the wires.
9. Additional Maintenance: Increase your frequency of disassembly, inspection
and lubrication of the following items: This is necessary after extended wet
use or if the vehicle will not be used for an extended period of time (such as a
week or longer). This additional maintenance is needed to prevent any trapped
moisture from corroding internal steel components.
• Stub axle housing bearings: Remove, clean, and re-oil the bearings.
• 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. To remove the cover, remove the two 3x8mm button-head cap screws.
2. 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.
3. Remove the wire clamp by removing the two 2.5x8mm cap screws.
4. Unplug the servo cables from the receiver and remove the receiver.
Receiver Installation
1. Always install the wires into the RX 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 (A). The excess wire will be bundled inside
the receiver box. Label which wire is for which channel.
4. Apply small bead of silicone grease (Traxxas part #1647)
to the wire clamp (B).
5. Install the wire clamp and tighten the two 2.5x8mm cap
screws securely.
6. Install the receiver into the box and plug the wires into
receiver (C). Refer to page 9 for the wiring diagram.
7. 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 any way.
8.Install the cover and tighten the two 3x8mm buttonhead cap screws securely.
9. Inspect the cover to make sure that the O-ring seal is
not visible.
Adjusting your Model
Once you become familiar with driving your model, you might
need to make adjustments for better driving performance
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
0° rods so
your transmitter to neutral. Now, adjust your servo and tie
that both wheels are pointing straight ahead and are parallel to
each other (0-degrees toe-in). This will ensure the same amount of
steering in both directions. For increased stability add one- to twodegrees of toe in to each front wheel. Use the turnbuckles to adjust
the alignment.
Adjusting the Camber
The camber angle of both
the front and rear wheels can
be adjusted with the camber
rods (upper turnbuckles).
Use a square or right-angle
triangle to set the camber
accurately. The stock-1camber
of the front wheels is -1
degree of camber. In the
rear, the stock camber is -1.5
degrees. These adjustments
should be set with the truck
positioned at its°normal ride
height with a battery installed.
Front Camber
Rear Camber
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 the0°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.
Shock Mounting Positions
-1.5° a
Big bumps
and rough terrain require
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
help reduce body roll (increased roll
stiffness), dive during braking, and
squat during acceleration.
The suspension of your model has
been set up for off-road performance
(position 1 on the front suspension
arms and position 2 on the rear
suspension arms). If you plan on
driving on hard surfaces the following
changes should be made:
All of the toe links are installed
on the truck so the left hand
thread indicators point to the
same direction. This makes it
easier to remember which way
to turn the wrench to increase
or decrease toe link length
(the direction is same at all
four corners). Note that the
groove in the hex indicates
the side of the toe link with
the left-hand threads.

Adjusting Your Model
Do not run your model with
the slipper clutch adjusting
spring fully compressed. The
minimum recommended
slipper clutch setting is 1/2
turn counter-clockwise from
fully compressed.
Motor and Gearing
There are two different types of aftermarket motor which can be
purchased for your model, stock and modified. Stock motor 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 motor are more
expensive, may feature ball bearings and come in a variety of wire
thicknesses and 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 motor.
Modified motor should be geared lower (higher numerically) than
stock motor because they reach their maximum power at higher
RPM’s. 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
20 • Slash
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 each model provides good overall
acceleration and top speed. If you want more top speed and less
acceleration install the included optional large pinion gear (more
teeth). If you want more acceleration and less top speed, use a
smaller optional (not included) pinion gear. The included optional
large pinion gear is intended for high-speed running on hard
surfaces, and this gearing is

range of gear combinations. This
does NOT imply that these gear
combinations should be used. Overgearing (bigger pinions, smaller

To achieve a good starting
point for the slipper clutch,
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.
Adjusting the Slipper Clutch
The model is equipped with an
adjustable slipper clutch which
is built into the large spur gear.
The 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 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
counter-clockwise 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.

To set the gear mesh, cut a narrow strip
of notebook paper and run it into the
gear mesh. Loosen the motor screws and
slide the motor and pinion gear into the

should be able to run a fresh strip of paper
through the gears without binding them.
Centering Your Servo
If the trim controls on your transmitter seem off, you may need to
recenter 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. The
white wire on the servo lead is positioned towards the crystal.
3. Place fresh “AA” batteries in the transmitter and turn the
transmitter power switch on.
4. Turn the throttle and steering trim adjustments on the
transmitter to the center “0” position.
5. Disconnect motor wires. Connect a fresh battery pack to the
speed control and turn on the ESC (see page 14). The servo will
automatically jump to its center position. The servo horn may
now be installed onto the servo output shaft.
6. Check servo operation by turning the steering wheel back
and forth to ensure that the mechanism has been centered
properly and you have equal throw in both directions. Repeat
1-6 if necessary.

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.
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.
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. There are several components which will wear
out from use: the servo saver (Traxxas part #3744), the bellcrank
22 • Slash
Shocks: Keep the oil level in the shocks full. Use only 100%
pure silicon 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 and Inspect the spur gear for wear and
check the tightness of set screws in the pinion gears. Tighten,
clean, or replace components as needed.
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.

Radio system does not work properly:
If the power light on the transmitter does not come on, check for
proper battery installation and that the batteries are new and/or fully
charged. If the power light is blinking, then the transmitter batteries
are weak and should be replaced. See page 11 for more details.
If the transmitter light is on but the radio is still not responding, check
for proper installation of batteries in the model and that the batteries
are new and/or fully charged. Check to make sure the on/off switch
on the model is in the on position. Check for damaged wires, a loose
crystal, or loose connections. See page 11 for more details.
Short radio range:
If the radio range appears short, then first check to make sure
the transmitter antenna is fully extended and that the antenna
in the model is in place and has not been cut or damaged. Next,
make sure the batteries are all fully charged. Finally, if you are still
experiencing short range, try a different location. Sometimes there
can be interference from various sources that can cause your radio
to malfunction.
Steering channel works but the motor will not run:
The speed control has thermally shut down (see page 15). Allow
the speed control to cool down. Use a milder motor or a smaller
pinion gear. Check the drive train for restrictions. Check the motor
connections. Check the motor.
Make sure the speed control is plugged into the throttle channel of
the receiver. Check operation of the throttle channel with a servo.
Bad battery or motor. Check the operation with known good battery
and motor.
XL-5: Possible internal damage. Return the XL-5 to Traxxas for service.
Motor and steering servo do not work:
Check the wires, radio system, crystals, battery and motor
connectors, and the battery pack.
Possible internal damage. Return the XL-5 to Traxxas for service.
Motor runs backwards:
Motor wired backwards - Check the wiring and correct.
XL-5 will not go into programming mode:
Make sure the XL-5 is plugged into Channel 2 (the throttle channel)
on the receiver. If it is plugged into the battery terminal, it will not
go into programming mode.
Be sure the XL-5 is turned off before trying to program or select
a profile.
Unplug battery, reconnect, and repeat programming instructions
on page 15.
Receiver glitches/throttle stutters during acceleration:
Motor capacitors broken or missing - Check and replace capacitors.
The receiver or antenna is too close to power wires or the batteries.
Bad connections - Check the wiring and connectors.
Motor worn - Replace the motor.
Excessive current to motor - Use a milder motor or a smaller
pinion gear.
Model runs slowly / slow acceleration:
Check the motor and battery connectors.
Check to see if XL-5 is in Profile #3 (50% throttle)
Bad battery or motor. Check the operation with known good
battery and motor.
Incorrect transmitter or speed control adjustment. Refer to the
“TQ Radio System Adjustments” (page 12) and “Adjusting the
Electronic Speed Control” (page 15) sections.
Model will not go in reverse:
Make sure the throttle trim is in the correct position (green light on
XL-5 should be solid)
Check for correct XL-5 profile (Profile #2 does not have reverse).
Motor runs as soon as the battery is plugged in:
Before turning on XL-5: Internal damage, return XL-5 to Traxxas
for service.
Keep stripping spur gears:
Improper gear mesh, refer to “Adjusting Gear Mesh” on page 21.
Improperly adjusted slipper clutch, refer to “Adjusting the
Slipper Clutch” on page 20.
