Introduction
Thank you for purchasing a Traxxas T-Maxx Nitro Monster Truck.
Traxxas engineers have loaded your T-Maxx with innovative
features and incredible “drive-over-anything” performance that
you won’t find anywhere else!
Your T-Maxx combines automatic, two-speed shifting in forward
and reverse, with powerful four-wheel disc braking.The
patented transmission design and three-channel TQ-3 radio
system put these functions right at your fingertips.
The new TRX 2.5 engine is the most powerful engine of its size
ever available in a Ready-To-Run truck. Two years of engineering
development and advanced design, along with thousands of
hours of testing, puts the TRX 2.5 in a class by itself. Each part of
the TRX 2.5—from the air filter on the slide carburetor, to the tip
on the dyno-tuned exhaust system—has been carefully
engineered to provide maximum power over the broadest RPM
range.
Traxxas was the first with standard on-board electric starting.
The new second generation EZ-Start has evolved into an
incredibly advanced and reliable starting solution, featuring
thermal protection for the motor and built-in diagnostics to
monitor the condition of the glow plug.
Obviously, there’s much going on between the wheels of your
T-Maxx. In this manual, we’ll take you step-by-step through all
necessary set-up, break-in, tuning, and operating procedures.
Even if you are an experienced R/C enthusiast, it is
important for you to read and follow the procedures in this
manual. Pay particular attention to the fuel requirements
and break-in procedures. The advanced design of the TRX
2.5 engine does not follow old-fashioned thinking
regarding fuel and break-in procedures.

All of us at Traxxas want you to safely enjoy your new T-Maxx.
Operate your T-Maxx sensibly and with care, and it will be
exciting, safe, and fun for you and those around you. Failure to
operate your T-Maxx 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
R/C fuel is dangerous and highly poisonous. Always follow all
directions and precautions printed on the fuel container.
R/C fuel, especially when in a fuel dispensing bottle, may
look like a cool drink to a child. Keep all fuel out of the reach
of children at all times. Do not place fuel containers on the
ground where children can get to them while you are
driving.
R/C fuel is flammable. Never allow smoking, sparks, heat or
flame in the presence of fuel or fuel vapors.
The engine and exhaust system may become extremely hot
during use. Be careful not to touch the parts, especially when
refueling or stopping the engine.
Prolonged exposure to the engine exhaust can be harmful.
Avoid breathing the engine exhaust. Always run your T-Maxx
outdoors, in a well-ventilated area. Never run the engine
indoors.
Don’t operate your T-Maxx at night, or anytime your line of
sight to the model may be obstructed or impaired in any way.
Never operate your T-Maxx in crowds of people or busy
pedestrian areas.The T-Maxx is large and fast, and may cause
injury to those unaware of its presence.
Because the T-Maxx is controlled by radio, it is subject to
radio interference from many sources beyond your control.
Since radio interference can cause momentary loss of
control, always allow a safety margin in all directions around
your model to prevent collisions.
The engine can be loud. If the noise makes you
uncomfortable, wear ear protection. Be considerate of your
neighbors by not running your model early in the morning
or late in the evening.
Most importantly, use good common sense at all times. ▼▼ ▼▼
▼▼▼▼ ▼▼
All instructions
and precautions
outlined in this
manual should be strictly
followed to ensure safe
operation of your T-Maxx.
The T-Maxx is not
intended for use
by those under 16
years of age without the
supervision of a
responsible and
knowledgeable adult.

The tires on your T-Maxx must be glued to the rims using CA tire
glue to prevent the rims from spinning inside the tires.You can
glue the tires without removing the wheels from the truck. For
clarity, these instructions show the process with the wheels
removed.
1. Remove a wheel from the
T-Maxx using the larger
(8mm) end of the glow plug
(universal) 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 3 wheels.
4. Reinstall the wheels, making
sure none of the axle pins
have fallen out from behind
the hex hubs.
Always wear safety
glasses to prevent
glue from
splattering into your eyes.
The acetone in
fingernail polish
remover will
remove excess glue from
your fingers.
For best results
while gluing, clean
the bead of the
tires and the grooves of
the wheels with denatured
alcohol before applying
glue. This removes any
mold release agent residue
from the tires and wheels,
providing a better bond.

Decorating Your T-Maxx
Applying The Decals
The ProGraphix painted
body is covered with a
protective film for shipping.
You must remove this film
before applying any decals.
To remove the film, lift a
corner of the film and
carefully pull it off the body
in one continuous piece.
Your T-Maxx decals are die-
cut for easy removal. Use a
hobby knife to lift the
corner of a decal and lift it
from the backing.
Carefully position the decal
over the desired location
and press one side on the
body. Pull the decal tight
and use a finger to gradually
smooth out any air bubbles
as you apply the decal.
Look at the photos on the box for typical decal placement.

Radio System Terminology
Please take a moment to familiarize yourself with these radio-
system terms.They will be used throughout this manual.
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.
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.
Frequency band - The radio frequency used by the transmitter
to send signals to your T-Maxx. All Traxxas RTR models operate
on a 27 MHz frequency band.
Neutral position - The standing position that the servos seek
when the transmitter controls are at the neutral setting.
NiCad - Refers to rechargeable, nickel-cadmium batteries. The
most economical choice, since they may be recharged up to
500 times.
Receiver - The radio unit inside your T-Maxx that receives
signals from the transmitter and relays them to the servos.
Servos - Small motor units in your T-Maxx that operate the
throttle, shifting, and steering mechanisms.
Three-channel radio system - The TQ-3 radio system,
consisting of the receiver, the transmitter, and the servos.The
system uses three channels: one to operate the throttle, one to
shift the transmission, and one to operate the steering.
Transmitter - The hand-held radio unit that sends throttle and
steering instructions to your T-Maxx.
Trim - The fine-tuning adjustment of the neutral position of the
servos, made by turning the throttle and steering trim knobs
on the face of the transmitter.

The Traxxas TQ-3 Radio System
Installing Transmitter Batteries
Your TQ-3 transmitter uses 8 AA batteries. The battery
compartment is located at 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
receiver batteries in the model.
Use the Right Batteries
Your transmitter and receiver
use AA batteries. Use new
alkaline batteries, or
rechargeable batteries such as
NiCad or Ni-MH (nickel-metal
hydride) batteries in your
transmitter and receiver. Make
sure rechargeable batteries are
fully charged according to the
manufacturer’s instructions.
If you use rechargeable
batteries in your transmitter, be
aware that when they begin to
lose their charge, they lose
power much more quickly than
regular alkaline batteries.
Caution: Discontinue
running your T-Maxx 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.
CH.3 CH.2 CH.1

Installing Receiver Batteries
The radio receiver in your T-Maxx uses 4 AA batteries.The battery
holder for the receiver batteries is located underneath the battery
cover. The battery cover can be identified by the on/off switch.
1. Remove the battery cover by removing the two 3x10mm
roundhead self-tapping screws from the cover.
2. Remove the battery holder and install 4 AA alkaline batteries.
Make careful note of the battery polarity by comparing
against the diagrams in the battery holder.
3. Insert the battery holder into the battery cover.
4. Reinstall the battery cover and secure with the screws
(see sidebar!).
On/Off
Switch
4-cell
battery
holder
Direct the battery
wires through the
slot in the battery
cover. If the wires are not
properly routed, they may
become broken or shorted,
causing radio system
failure and loss of control.
If you use rechargeable
batteries in your receiver,
be aware that when they
begin to lose their charge,
they lose power much more
quickly than regular
alkaline batteries. Signs of
weak receiver batteries
include sluggish steering
response and shortened
radio range. Caution:
Discontinue running your
T-Maxx at the first sign of
weak batteries to avoid
losing control.
If the radio system
doesn’t appear to
work when the
transmitter and receiver
switches are turned on,
check for correct battery
installation.

Spray a little window
cleaner on the
antenna wire to
make it easier to push
through the antenna tube.
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.
Setting Up the Antenna
You must install the antenna mast (tube) before you operate
your T-Maxx. You’ll find the plastic antenna tube and tip in the
bag with your manuals and documentation.
1. Locate the black antenna wire that exits the receiver cover.
The T-Maxx receiver cover is mounted on the top of the
chassis, near the front.
2. Pull the wire straight with your fingers and then insert the
end of the wire into one end of the antenna tube. Push the
wire all the way through the antenna tube.
3. Pull the remaining wire through the antenna tube, and then
insert the base of the antenna tube into the molded post on
top of the receiver cover.
4. Fold the remaining antenna wire over the top of the tube
and secure it with the antenna tip.
5. On the transmitter, always fully extend the telescoping
antenna when running your T-Maxx. Make a habit of holding
the transmitter so that the antenna points straight up.

Other TQ-3 Radio System Adjustments
In addition to the electronic throttle and steering trim controls,
your radio system features throttle neutral adjustment and
servo reversing switches.
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.There are two settings
available:
50/50: Allows equal travel for both acceleration and braking.
70/30: Allows more throttle travel (70%) and less
brake travel (30%).
50/50 is the required setting for the T-Maxx with
the TRX 2.5 racing engine.
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.This control has been preset for
you at the factory. If necessary, adjust the control so that the
carburetor is at idle, and the brakes are not applied (the model
will roll freely). Do not use the throttle trim to raise or lower the
engine idle speed. Make the idle speed adjustment on the
carburetor.
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
front 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-3 Radio System Rules
Each time you prepare to run your
T-Maxx, 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 truck is assigned to.
Always turn your TQ-3 transmitter on first and off last. This
procedure will help to prevent your T-Maxx from receiving
stray signals from another transmitter, or other source, and
running out of control.
Always have the transmitter and receiver turned on before
you start the engine. Never turn the radio system off while
the engine is running.The on/off switch in the model only
turns the receiver on and off. It does not turn off the engine.
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 T-Maxx.

The Traxxas TQ-3 Radio System
Using the TQ-3 Radio System
The TQ-3 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. Turn on the receiver switch in the model.The switch is
located on the battery cover.
3. Position the T-Maxx so that its front wheels are off the
ground.
4. 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 receiver
batteries.
5. When looking down at model, the front wheels should be
pointing straight ahead. If the wheels are turned slightly to
the left or right, slowly adjust the steering trim control on the
transmitter until they are pointing straight ahead.
6. Operate the throttle trigger on the transmitter and check for
rapid operation of the throttle servo.When the throttle
trigger is pulled back, the carburetor should open. When the
throttle trigger is pushed all the way forward, the brake
should lock.
7. Operate the shift button on the transmitter and check for
rapid operation of the shifting servo. Push the shift button
down for forward.The servo will push the transmission shift
rodinto the transmission. Push the shift button up for reverse
and the servo will pull the shift rod out of the transmission.
8. Once adjustments are made, turn off the receiver on your
T-Maxx, followed by the handheld transmitter.
