4 • TRAXXAS
All of us at Traxxas want you to safely enjoy your new model. Operate
your model sensibly and with care, and it will be exciting, safe, and
fun for you and those around you. Failure to operate your model in
a safe and responsible manner may result in property damage and
serious injury. The precautions outlined in this manual should be
strictly followed to help ensure safe operation. You alone must see
that the instructions are followed and the precautions are adhered to.
Important Points to Remember
• Your model is not intended for use on public roads or congested areas
where its operation can conflict with or disrupt pedestrian or vehicular
traffic.
• Never, under any circumstances, operate the model in crowds of people.
Your model is very fast and could cause injury if allowed to collide with
anyone.
• Because your model is controlled by radio, it is subject to radio
interference from many sources that are beyond your control. Since
radio interference can cause momentary losses of radio control, always
allow a safety margin in all directions around the model in order to
prevent collisions.
• The motor, battery, and speed control can become hot during use. Be
careful to avoid getting burned.
• Don’t operate your model at night, or anytime your line of sight to the
model may be obstructed or impaired in any way.
• Most importantly, use good common sense at all times.
Speed Control
Your model’s electronic speed control (ESC) 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.
• Disconnect the Battery: Always disconnect the battery or batteries
from the speed control when not in use.
• 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.
• Don’t Get Burned: The ESC and motor can become extremely hot
during use, so be careful not to touch them until they cool. Supply
adequate airflow for cooling.
• Use the Factory-Installed Connectors: Do not change the battery
and motor connectors. Improper wiring can cause fire or damage to
the ESC. Please note that modified speed controls can be subject to
a rewiring fee when returned for service.
• No Reverse Voltage: The ESC is not protected against reverse
polarity voltage.
• No Schottky Diodes: External Schottky diodes are not compatible
with reversing speed controls. Using a Schottky diode with your
Traxxas speed control will damage the ESC and void the 30-day
warranty.
• Always adhere to the minimum and maximum limitations of the
speed control as stated in the specifications table in the Owner’s
Manual. If your ESC operates on two batteries, do not mix battery
types and capacities. Use the same voltage and capacity for both
batteries. Using mismatched battery packs could damage the
batteries and electronic speed control.
Recycling Traxxas Power Cell NiMH Batteries
Traxxas strongly encourages you to recycle your Power Cell NiMH
battery when it has reached the end of its useful life. Do not throw your
battery in the trash. All Power Cell NiMH battery packs display the RBRC
(Rechargeable Battery Recycling Corporation) icon, indicating they are
recyclable. To find a recycling center near you, ask your local hobby dealer
or visit www.call2recycle.org.
SAFETY PRECAUTIONS
WARNING! CAUTION! DANGER!
FIRE HAZARD! Your model is able to use LiPo
batteries. Charging and discharging batteries has the
potential for fire, explosion, serious injury, and property damage
if not performed per the instructions. Before use, read and follow
all manufacturer’s instructions, warnings, and precautions. In
addition, Lithium Polymer (LiPo) batteries pose a SEVERE risk of
fire if not properly handled per the instructions and require special
care and handling procedures for long life and safe operation. LiPo
batteries are intended only for advanced users that are educated
on the risks associated with LiPo battery use. Traxxas does not
recommend that anyone under the age of 14 use or handle LiPo
battery packs without the supervision of a knowledgeable and
responsible adult. Dispose of used batteries according to the
instructions.
Important Warnings for users of Lithium Polymer (LiPo)
batteries:
• LiPo batteries have a minimum safe discharge voltage threshold
that should not be exceeded. The electronic speed control is
equipped with built-in Low-Voltage Detection that alerts the
driver when LiPo batteries have reached their minimum voltage
(discharge) threshold. It is the driver’s responsibility to stop
immediately to prevent the battery pack from being discharged
below its safe minimum threshold.
• Low-Voltage Detection is just one part of a comprehensive plan
for safe LiPo battery use. It is critical to follow all instructions for
safe and proper charging, use, and storage of LiPo batteries. Make
sure you understand how to use your LiPo batteries. If you have
questions about LiPo battery usage, please consult with your local
hobby dealer or contact the battery manufacturer. As a reminder,
all batteries should be recycled at the end of their useful life.
•ONLY use a Lithium Polymer (LiPo) balance charger with a balance
adapter port to charge LiPo batteries. Never use NiMH or NiCadtype chargers or charge modes to charge LiPo batteries. DO NOT
charge with a NiMH-only charger. The use of a NiMH or NiCad
charger or charge mode will damage the batteries and may cause
fire and personal injury.
•NEVER charge LiPo battery packs in series or parallel. Charging
packs in series or parallel may result in improper charger cell
recognition and an improper charging rate that may lead to
overcharging, cell imbalance, cell damage, and fire.
•ALWAYS inspect your LiPo batteries carefully before
charging. Look for any loose leads or connectors,
damaged wire insulation, damaged cell packaging, impact
damage, fluid leaks, swelling (a sign of internal damage), cell
deformity, missing labels, or any other damage or irregularity.
If any of these conditions are observed, do not charge or use
the battery pack. Follow the disposal instructions included with
your battery to properly and safely dispose of the battery.
•DO NOT store or charge LiPo batteries with or around other
batteries or battery packs of any type, including other LiPos.
•Store and transport your battery pack(s) in a cool dry place.
DO NOT store in direct sunlight. DO NOT allow the storage
temperature to exceed 140°F or 60°C, such as in the trunk of a
car, or the cells may be damaged and create a fire risk.
•DO NOT disassemble LiPo batteries or cells.
•DO NOT attempt to build your own LiPo battery pack from
loose cells.
Charging and handling precautions for all battery types:
•BEFORE you charge, ALWAYS confirm that the charger
settings exactly match the type (chemistry), specification, and
configuration of the battery to be charged.
•DO NOT attempt to charge non-rechargeable batteries (explosion
hazard), batteries that have an internal charge circuit or a
protection circuit, batteries that have been altered from original
manufacturer configuration, or batteries that have missing or
unreadable labels, preventing you from properly identifying the
battery type and specifications.
•DO NOT exceed the maximum manufacturer recommended charge
rate.
• DO NOT let any exposed battery contacts or wires touch each other.
This will cause the battery to short circuit and create the risk of fire.
• While charging or discharging, ALWAYS place the battery (all
types of batteries) in a fire retardant/fire proof container and on
a non-flammable surface such as concrete.
• DO NOT charge batteries inside of an automobile. DO NOT charge
batteries while driving in an automobile.
• NEVER charge batteries on wood, cloth, carpet, or on any other
flammable material.

TRAXXAS TQi 2.4GHz RADIO SYSTEM
INTRODUCTION
Applying the Decals
The main decals for your
model have been applied at
the factory. Additional decals
have been printed on selfadhesive clear mylar and are
die-cut for easy removal. Use
a hobby knife to lift the corner
of a decal and lift it from the
backing.
Your model includes the latest Traxxas TQi 2.4GHz transmitter with
Traxxas Link™ Model Memory. The transmitter’s easy-to-use design
provides instant driving fun for new R/C enthusiasts, and also offers
a full complement of pro-level tuning features for advanced users
– or anyone interested in experimenting with the performance of
their model. The steering and throttle channels feature adjustable
Exponential, End Points, and Sub-Trims. Steering and braking DualRate are also available. Many of the next-level features are controlled
by the Multi-Function knob, which can be programmed to control
a variety of functions. The detailed instructions (page 29) and Menu
Tree (page 32) included in this manual will help you understand and
operate the advanced functions of the new TQi radio system. For
additional information and how-to videos, visit Traxxas.com.
RADIO AND POWER SYSTEM TERMINOLOGY
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.
Please take a moment to familiarize yourself with these radio and
power system terms. They will be used throughout this manual.
A detailed explanation of the advanced terminology and features
of your new radio system begins on page 29.
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 TQi system
automatically selects and locks onto an open frequency and offers
superior resistance to interference and “glitching.”
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.
Brushless Motor - A D/C brushless motor replaces the brushed
motor’s traditional commutator and brush arrangement with
intelligent electronics that energize the electromagnetic
windings in sequence to provide rotation. Opposite of a brushed
motor, the brushless motor has its windings (coils) on the
perimeter of the motor can and the magnets are mounted to the
spinning rotor shaft.
9
10 • TRAXXAS
Cogging - Cogging is a condition sometimes associated with
brushless motors. Typically, it is a slight stutter noticed when
accelerating from a stop. It happens for a very short period as the
signals from the electronic speed control and the motor synch
with each other. The VXL-3s electronic speed control is optimized
to virtually eliminate cogging.
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 VXL-3s electronic
speed control uses advanced circuitry 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.
kV Rating - Brushless motors are often rated by their kV number.
The kV rating equals no-load motor rpm with 1 volt applied. The
kV increases as the number of wire turns in the motor decreases.
As the kV increases, the current draw through the electronics
also increases. The Velineon 3500 motor is a 3500 kV motor
optimized for the best speed and efficiency in lightweight 1/10
scale models.
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. LiPo battery packs are 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.
TRAXXAS TQi 2.4GHz RADIO SYSTEM
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.
The Velineon power system is optimized to reduce electrical
resistance and the resulting power-robbing heat.
Thermal Shutdown Protection - Temperature sensing electronics
used in the VXL-3s electronic speed control 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 TQi 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.
Rotor - The rotor is the main shaft of the brushless motor. In a
brushless motor, the magnets are mounted to the rotor, and the
electromagnetic windings are built into the motor housing.
IMPORTANT RADIO SYSTEM PRECAUTIONS
Sensored - Sensored refers to a type of brushless motor that
uses an internal sensor in the motor to communicate rotor
position information back to the electronic speed control. The
VXL-3s electronic speed control is able to use sensored motors
when applications benefit from them (such as some sanctioned
racing classes).
• DO NOT CUT any part of the receiver’s antenna wire. Cutting the
antenna will reduce range.
Sensorless - Sensorless refers to a brushless motor that uses
advanced instructions from an electronic speed control to
provide smooth operation. Additional motor sensors and
wiring are not required. The VXL-3s electronic speed control is
optimized for smooth sensorless control.
Servo - Small motor unit in your model that operates the steering
mechanism.
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
No
No
No
No
• Do not kink the receiver’s antenna wire. Kinks in the antenna wire
will reduce range.
• Extend the antenna wire in the model as far as possible for
maximum range. It is not necessary to extend the antenna wire out
of the body, but wrapping or coiling the antenna wire should be
avoided.
• Do not allow the antenna wire to extend outside the body without
the protection of an antenna tube, or the antenna wire may get
cut or damaged, reducing range. It is recommended to keep the
wire inside the body (in the antenna tube) to prevent the chance
of damage.
Solder Tabs - Accessible, external contacts on the motor that
allows for easy wire replacement. The Velineon 3500 is equipped
with solder tabs.
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 knobs
on the face of the transmitter. Note: The Multi-Function knob must
be programmed to serve as a throttle trim adjustment.

INSTALLING THE BATTERY PACK
SETTING UP THE ANTENNA
Install the battery pack with the battery wires facing the front of
the model. Swing the battery hold down towards the chassis and
snap (lock) the end into the front hold-down retainer.
The receiver antenna has been set up
and installed from the factory. The
antenna is secured by a 3x4mm set
screw. To remove the antenna tube,
simply remove the set screw with the
included 1.5mm wrench.
Note: The battery hold-down can be rotated on its pivot to
accommodate different height battery packs.
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.
Antenna
Tip
When reinstalling the antenna,
Antenna
Tube
first slide the antenna wire into the
bottom of the antenna tube until
the white tip of the antenna is at the
Antenna
top of the tube under the black cap.
Mount
Next, insert the antenna tube into
the mount while making sure that
the antenna wire is in the slot in the antenna mount; then, install
the set screw next to the antenna tube. Use the supplied 1.5mm
wrench to tighten the screw just until the antenna tube is securely
in place. Do not over tighten. Do not bend or kink the antenna
wire! See the side bar for more information. Do not shorten the
antenna tube.

Neutral
Brake/Reverse
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 reverse.
70/30: Allows more throttle travel (70%) and less reverse travel (30%).

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.
1
Always turn your
transmitter on first.
Remember, always turn the
TQi transmitter on first and
off last to avoid damage to
your model.
2
Plug in the battery.
3
Turn on the model.
• Always use new batteries for the radio system. Weak batteries will
limit the radio signal between the receiver and the transmitter.
Loss of the radio signal can cause you to lose control of your model.
Note: We strongly recommend to leave this control in its factory
location until you become familiar with all the adjustments and
capabilities of your model. To change the throttle neutral adjust
position, turn the transmitter off before adjusting the neutral
position. You will need to reprogram your electronic speed control
to recognize the 70/30 setting. Turn to ESC Setup Programming on
page 18 for instructions.
Steering Trim
The electronic steering trim located on the
face of the transmitter adjusts the neutral
(center) point of the steering channel.
Note: Traxxas Stability Management (TSM) must be completely
turned off while adjusting steering trim. See page 17 for TSM
adjustments.
Automatic Fail-Safe
The TQi transmitter and
receiver are equipped
with an automatic failsafe system that does not
require user programming.
In the event of signal loss
or interference, the throttle
will return to neutral and
the steering will hold its last
commanded position. If the
Fail-Safe activates while you
are operating your model,
determine the reason for
signal loss and resolve the
problem before operating
your model again.
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.
Multi-Function Knob
The Multi-Function knob can be programmed
to control a variety of functions. From the
factory, the Multi-Function knob controls
Traxxas Stability Management (TSM).
For more detail on TSM, refer to page 17.

USING THE RADIO SYSTEM
Using Reverse: While driving,
push the throttle trigger
forward to apply brakes.
Once stopped, return the
throttle trigger to neutral.
Push the throttle trigger
forward again to engage
proportional reverse.
The TQi Radio System has been pre-adjusted at the factory. 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 on a block or a stand so that all the tires are
off the ground. Make sure your hands are clear of the moving
parts of the model.
3. Plug the battery pack in the model into the speed control.
4. The on/off switch is integrated into the speed control. Press
and release the EZ-Set button on the speed control to turn the
model on. The LED will shine RED or GREEN (see note below). To
turn the VXL-3s off, press the set button until the LED turns off.
Note: If the LED shines green after the speed control is turned
on, Low-Voltage Detection is activated. This may cause poor
performance from NiMH battery packs. Make sure to turn the
Low-Voltage Detection on when using LiPo batteries. Never
use LiPo batteries while Low-Voltage Detection is turned off.
See page 18 for more information.
5. Turn the steering wheel on the transmitter back and forth and
check for rapid operation of the steering servo. Also, check that
the steering mechanism is not loose or binding. If the steering
operates slowly, check for weak batteries.
6. When looking down at the
model, the front wheels
should be pointing straight
ahead. If the wheels are
turned slightly to the left
or right, turn off TSM (see
page 17) and slowly adjust
the steering trim control
on the transmitter until they are pointing straight ahead; then,
return the multi-function knob to the desired TSM setting.
7. Gently operate the throttle trigger to ensure that you have
forward and reverse operation, and that the motor stops when
the throttle trigger is at neutral. Warning: Do not apply full
throttle in forward or reverse while the model is elevated.

16 • TRAXXAS
8. Once adjustments are made, turn off the receiver on your model,
followed by the hand-held transmitter.
Range-Testing the Radio System
Before each running session with your model, you should range-test
your radio system to ensure that it operates properly.
1. Turn on the radio system and check its operation as described in
the previous section.
2. Have a friend hold the model. Make sure hands and clothing are
clear of the wheels and other moving parts on the model.
3. Walk away from the model with the transmitter until you reach
the farthest distance you plan to operate the model.
4. Operate the controls on the transmitter once again to be sure
that the model responds correctly.
5. Do not attempt to operate the model if there is any problem
with the radio system or any external interference with your
radio signal at your location.
Higher Speeds Require Greater Distance
The faster you drive your model, the more quickly it will near the
limit of radio range. At 60mph, a model can cover 88 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 car’s running area, not
the far end, so you drive the car 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.
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.
TQi 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 transmitter’s SET button as you switch the
transmitter on. The transmitter’s LED will flash red slowly.
Release the SET button.
2. Press and hold the receiver’s LINK button as you switch on
the speed control (by pressing the EZ-Set button). Release the
LINK button.
3. When the transmitter and receiver’s LEDs turn solid green, the
system is bound and ready for use. Confirm that the steering
and throttle operate properly before driving your model.
TRAXXAS TQi 2.4GHz RADIO SYSTEM
TRAXXAS STABILITY MANAGEMENT (TSM)
Traxxas Stability Management or
TSM allows you to experience all
the speed and acceleration that
was engineered into your Traxxas
model by helping you to maintain
control of the vehicle in low-traction situations. TSM helps provide
straight ahead full-throttle acceleration on slippery surfaces,
without fishtailing, spinouts, or loss of control. TSM also dramatically
improves braking control. High speed cornering and control is also
made possible as TSM makes corrections for you, without intruding
on your fun, or creating unexpected side effects.
The Multi-Function knob on
the TQi transmitter has been
programmed to control TSM. The
recommended (default) setting
for TSM is to rotate the knob to
the 12:00 position (the zero mark
on the dial).
Recommended setting
Turn the knob clockwise to
increase assistance; turn the
knob counterclockwise to
decrease assistance. Turn the
Decrease
knob counterclockwise to its
assistance
stop to turn TSM completely off.
Note: TSM is deactivated
TSM off
automatically when driving or
braking in 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.
Increase
assistance
When driving on surfaces with some traction, decrease the TSM
setting to allow the vehicle to feel more “loose” for power sliding,
drifting, and so on. On surfaces with very little traction (loose dirt,
smooth concrete, ice/snow), increase TSM to maximize acceleration
and control.
Drive with TSM on and off to test how it is making your control of
the vehicle easier and more precise. For more information, visit
Traxxas.com/tsm.
Note: TSM must be completely turned off while adjusting steering
trim.

VXL-3s Battery Settings (Low-Voltage Detection Setting)
The Velineon VXL-3s electronic speed control is equipped with built-in
Low-Voltage Detection. The Low-Voltage Detection circuitry constantly
monitors the battery voltage. When the battery voltage begins to reach the
minimum recommended discharge voltage threshold for LiPo battery packs,
the VXL-3s will limit the power output to 50% throttle. When the battery
voltage attempts to fall below the minimum threshold, the VXL-3s will shut
down all motor output. The LED on the speed control will slowly blink red,
indicating a low voltage shutdown. The VXL-3s will stay in this mode until a
fully charged battery is connected.
The VXL-3s speed control’s Low-Voltage Detection has been disabled for
best performance with NiMH batteries. 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 a LiPo battery 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 VXL-3s.
3. Press and release the EZ-Set button to turn the VXL-3s 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 VXL-3s is on and red.
2. Press and hold the EZ-Set button for ten seconds.
The LED will turn off and then light green. Also, a
“rising” musical tone will be emitted from the motor.
3. Low-Voltage Detection is now ACTIVATED.
To disable Low-Voltage Detection (NiMH setting):
1. Make sure the LED on the VXL-3s is on and green.
2. Press and hold the EZ-Set button for ten seconds.
The LED will turn off and then light red. Also, a
“falling” musical tone will be emitted from the
motor.
3. Low-Voltage Detection is now DISABLED.
Transmitter Adjustments for the VXL-3s ESC
Before attempting to program your VXL-3s 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.
18 • TRAXXAS
The transmitter should be adjusted as follows:
If the transmitter setting have been adjusted, reset them to the factory defaults.
1. Turn transmitter off.
2. Hold both MENU and SET.
3. Turn transmitter on.
4. Release MENU and SET. The transmitter LED will blink red.
5. Press MENU once. The transmitter LED will blink red twice repeatedly.
6. Press SET to clear settings. The LED will turn solid green and the transmitter is
restored to default.
VXL-3s Setup Programming (Calibrating your ESC and transmitter)

the vehicle on a stable block or stand so that all of the driven
wheels are off the ground. Disconnect motor wires “A” and “C” (see page 12),
this will assure the motor does not drive the wheels during testing. Do not test
programming without disconnecting the motor wires.
Note that in steps 1-7 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 1-7 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 VXL-3s on.
2. Apply forward throttle. The LED will turn off until full throttle power is reached.
At full throttle, the LED will illuminate 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 illuminate 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 illuminate red.
6. To stop, return the throttle trigger to neutral. Note that there is programmed
delay when changing from reverse to forward. This prevents damage to the
transmission on high-traction surfaces.
7. To turn the VXL-3s off, press the EZ-Set button until the LED turns off (.5 seconds).

LED Codes and Protection Modes
• Solid Green: VXL-3s power-on light. Low-Voltage Detection is
ACTIVATED (LiPo setting).
• Solid Red: VXL-3s power-on light. Low-Voltage Detection is
DISABLED (NiCad/NiMH setting). Never use LiPo batteries while
Low-Voltage Detection is disabled.
• Slow Blinking Red (with Low-Voltage Detection on): The VXL-3s
has entered Low-Voltage Protection. When the battery voltage
begins to reach the minimum recommended discharge voltage
threshold for LiPo battery packs, the VXL-3s will limit the power
output to 50% throttle. When the battery voltage attempts to
fall below the minimum threshold, the VXL-3s will shut down all
motor output. The LED on the speed control will slowly blink red,
indicating a low-voltage shutdown. The VXL-3s will stay in this
mode until a fully charged battery is connected.
• Fast Blinking Red: Thermal Shutdown Protection Stage 1. If the
motor has lower than normal power and the VXL-3s is hot, the VXL3s has entered Stage 1 Thermal Shutdown Protection to guard
against overheating caused by excessive current flow. If the motor
has no power and the VXL-3s is very hot, the VXL-3s has entered
Stage 2 Thermal Shutdown Protection and has automatically shut
down. Let the VXL-3s cool. Make sure your model is properly geared
for the conditions (see page 24).
• Very Fast Blinking Red: Thermal Shutdown Protection and Low
Voltage Protection (see above) have occurred at the same time.
• Alternating; Blinks Red then Green: If the motor has no power,
the VXL-3s has entered Over Voltage Protection. If a battery with
too high voltage is used, the VXL-3s will go into a fail-safe mode.
WARNING: If input voltage exceeds approximately 20-volts,
the ESC may be damaged. Do not exceed 12.6 maximum peak input
voltage.
• Blinking Green: The VXL-3s is indicating the transmitter
Throttle Trim is incorrectly set. If the Multi-Function knob is set to
throttle trim, then adjust the Throttle Trim to the middle “0” setting.
Patented Training Mode
(Profile #3) reduces forward
and reverse throttle by 50%.
Training Mode is provided
to reduce the power output,
allowing beginning drivers
to better control the model.
As driving skills improve,
simply change to Sport or
Race Mode for full-power
operation.
Tip For Fast Mode Changes
The VXL-3s is set to Profile 1
(Sport Mode) as the default.
To quickly change to Profile 3
(Training Mode), with the
transmitter on, press and
hold the SET button until the
light blinks red three times
and then release.
For full power, quickly change
back to Profile 1 (Sport Mode)
by pressing and holding the
SET button until the light
blinks red one time and
then releasing.
The VXL-3s has built-in
programming that prevents
accidental activation of
reverse while in forward
motion and vice-versa. You
must come to a complete
stop, release the throttle
trigger, then apply opposite
throttle to engage the motor
in the desired direction.

DRIVING YOUR MODEL
Now it’s time to have some fun! This section contains instructions
on driving and making adjustments to your model. Before you go
on, here are some important precautions to keep in mind.
• Allow the model to cool for a few minutes between runs. This is
particularly important when using high-capacity (2400mAh and
above) battery packs that allow extended periods of running.
Monitoring temperatures will extend the lives of the batteries and
motor.
• Do not continue to operate the model with low batteries or you
could lose control of it. Indications of low battery power include
slow operation and sluggish servos (slow to return to center). Stop
immediately at the first sign of weak batteries. When the batteries
in the transmitter become weak, the red power light will begin to
flash. Stop immediately and install new batteries.
• Do not drive the model at night, on public streets, or in large
crowds of people.
• If the model becomes stuck against an object, do not continue to
run the motor. Remove the obstruction before continuing. Do not
push or pull objects with the model.
• Because the model is controlled by radio, it is subject to radio
interference from many sources beyond your control. Since radio
interference can cause momentary losses of control, allow a safety
margin of space in all directions around the model in order to
prevent collisions.
• Use good, common sense whenever you are driving your model.
Intentionally driving in an abusive and rough manner will only
result in poor performance and broken parts. Take care of your
model so that you can enjoy it for a long time to come.
• When using optional pinions for top speed running, limit your
driving to paved surfaces only. Repetitive starting and stopping
and extensive drifting around turns will create excess heat and
overheat the ESC and/or motor. Running in grass and off-road
could also cause excessive loads on the electrical system.
10
20 • TRAXXAS
• 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 TQi 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 receiver box O-ring and cover are installed
correctly and secure. Make sure the screws are tight and the blue
O-ring is not visible protruding from the edge of the cover.
4. Confirm that your batteries can be used in wet conditions.
5. Use lower gearing (smaller pinion gears, as low as 19T, with
the stock 70-T spur gear) when running in mud, deep puddles,
snow, or other similar situations that will restrict the tires and
put much higher loads on the motor.
Motor Precautions
• Titan motor life can be greatly reduced in mud and water. If the
motor gets excessively wet or submerged, use very light throttle
(run the motor slowly) until the excess water can run out. Applying
full throttle to a motor full of water can cause rapid motor failure.
Your driving habits will determine motor life with a wet motor. Do
not submerge the motor under water.
• Do not gear the motor by temperature when running in wet
conditions. The motor will be cooled by water contact and will not
give an accurate indication of appropriate gearing.
After Running Your Vehicle in Wet Conditions
1. Drain the tires by spinning the tires at high speed to “sling” the
water out. One way to do this is to make several high-speed
passes on a flat, dry surface, if possible.
2. Remove the batteries.
3. Rinse excess dirt and mud off the car with low-pressure water,
such as from a garden hose. Do NOT use pressure washer
or other high-pressure water. Avoid directing water into the
bearings, transmission, etc.
4. Blow off the car with compressed air (optional, but
recommended). Wear safety glasses when using compressed air.
5. Remove the wheels from the car.
6. Spray all the bearings, drivetrain, and fasteners with WD-40® or
similar water displacing light oil.
TRAXXAS • 21
DRIVING YOUR MODEL
7. Let the car stand or you may blow off with compressed air.
Placing the car in a warm, sunny spot will aid drying. Trapped
water and oil will continue to drip from the car for a few hours.
Place it on a towel or piece of cardboard to protect the surface
underneath.
8. As a precautionary step, remove the sealed receiver box
cover. While unlikely, humidity or tiny amounts of moisture or
condensation may enter the receiver box during wet running.
This can cause long-term problems with the sensitive electronics
in the receiver. Removing the receiver box cover during storage
allows the air inside to dry. This step can improve the longterm reliability of the receiver. It is not necessary to remove the
receiver or unplug any of the wires.
9. Additional Maintenance: Increase your frequency of
disassembly, inspection, and lubrication of the following items.
This is necessary after extended wet use or if the vehicle will
not be used for an extended period of time (such as a week or
longer). This additional maintenance is needed to prevent any
trapped moisture from corroding internal steel components.
• Stub axle housing bearings: Remove, clean, and re-oil the
bearings.
• Titan motor: Remove the motor, clean with aerosol motor
cleaner, and re-oil the bushings with lightweight motor oil. Be
sure to wear eye protection when using spray aerosol cleaners.
RECEIVER BOX:
MAINTAINING A WATERTIGHT SEAL
Removing and Installing Radio Gear
The unique design of the receiver box allows the removal and
installation of the receiver without losing the ability to maintain a
watertight seal in the box. The patent-pending wire clamp feature
gives you the ability to also install aftermarket radio systems and
maintain the watertight features of the receiver box.
Removing the Receiver
1. To remove the cover, remove the three 2.5x10mm socket-head
cap screws.
2. To remove the receiver from the box, simply lift it out and set to
the side.
3. Unplug the servo cables from the receiver and remove the
receiver.
22 • TRAXXAS
Receiver Installation
1. Always install the wires into the receiver box before installing the
receiver.
2. Install the antenna wire and the servo
cables into the receiver box.
3. Arrange the wires neatly using the
wire guides in the receiver box. The
excess wire will be bundled inside the
receiver box. Label which wire is for
which channel.
4. Apply a small bead of silicone grease
(Traxxas part #1647) to the wire clamp.
5. Using double-sided adhesive foam
tape, install the receiver into the box.
Note: For best performance, it is recommended that the receiver
be installed in the original orientation as shown.
6. Plug the wires into the receiver. Refer to page 12 for the wiring
diagram.
7. Make sure the box light pipe is aligned
with the receiver LED. Make sure the
O-ring is properly seated into the
groove in the receiver box so that the
cover will not pinch it or damage it in
any way.
8. Install the cover and tighten the three 2.5x10mm socket-head
cap screws securely.
9. Inspect the cover to make sure that the O-ring seal is not visible.
ADJUSTING YOUR MODEL
Once you become familiar with driving your model, you might need
to make adjustments for better driving performance
Adjusting Gear Mesh
Incorrect gear mesh is the most
common cause of stripped spur
gears. Your model includes a fixed
gear positioning system to simplify
the process and ensure proper gear
mesh settings. Access the gears
by removing the four 3x12mm
button-head cap screws from the
gear cover; remove the gear cover.
Remove the motor/motor plate
assembly from the chassis.
To set the gear mesh, use the chart
in the sidebar to identify the screw
positions on the motor plate (A - K)
that correspond with the chosen
motor pinion gear size (19-T - 29-T). Remove the two screws from
the motor/motor plate and reinstall in the corresponding positions;
reinstall the motor/motor plate assembly in the chassis.
Shock Mounting Positions
Big bumps and rough terrain
require a softer suspension
with the maximum possible
suspension travel and
ride height. Racing on a
prepared track or on-road
use requires a lower ride
height and firmer, more
progressive suspension
settings. The more progressive suspension settings help reduce
body roll (increased roll stiffness), dive during braking, and squat
during acceleration. The suspension of your model has been set up
for on-road performance.
Fine Tuning the Shocks
The four shocks on the model greatly
influence its handling. Whenever
you rebuild your shocks or make any
changes to the pistons, springs, or
oil, always make changes to them in
pairs (front or rear). Piston selection
depends on the range of oil viscosities
that you have available. For example,
Pre-load
using a two-hole piston with a
Spacer
lightweight oil will, at one point, give
you the same damping as a three-hole
piston with heavier oil. We recommend
using the two-hole pistons with a
range of oil viscosities from 10W to
50W (available from your hobby shop).
The thinner viscosity oils (30W or less) flow more smoothly and are
more consistent, while thicker oils provide more damping. Use only
100% pure silicone shock oil to prolong seal life. The model’s ride
height can be adjusted by adding or removing the clip-on, spring
pre-load spacers. Adjust the ride height so that the suspension arms
are slightly above being parallel to the ground. Observe how the
model handles in turns. Proper set-up will add stability and help
prevent spin outs. Experiment with different springs and shock oils to
find what works best for your current track conditions.
Centering Your Servo
If the trim controls on your transmitter seem off, you may need to
re-center your servo. Additionally, whenever your servo has been
removed for service or cleaning, it must be re-centered prior to
installation in the model.
1. Disconnect the servo horn from the steering servo.
2. Connect the steering servo to channel 1 on the receiver. Connect
the electronic speed control (ESC) to channel 2.
3. Place fresh “AA” batteries in the transmitter and turn the
transmitter power switch on.
4. Turn off TSM (see page 17).
5. Turn the steering trim adjustment on the transmitter to the center
“0” position.
6. Elevate the model on a block or stand so that all of the tires are
off the ground. Connect a fresh battery pack to the speed control
and turn on the ESC (see page 18). The servo will automatically
jump to its center position.

Motors and Gearing
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 an extremely hot,
modified motor. A higher kV motor should be geared lower
(higher numerically) than a stock motor because it will reach its
maximum power at higher rpms. A higher kV motor that is geared
incorrectly can actually be slower than a correctly-geared, stock
motor. Use the following formula to calculate the overall ratio for
combinations not listed on the gear chart:
# Spur Gear Teeth
x 2.85 = Final Gear Ratio
# Pinion Gear Teeth
If you are worried that you might be over-geared, check the
temperature of the battery pack and motor. If the battery is
extremely hot, and/or the motor is too hot to touch, your model is
probably over-geared. If you are not able to run your model for at least
four minutes before the battery dies, then change to a lower gear
ratio. This temperature test assumes that the model is close to factory
stock weight and operates freely with no excessive friction, dragging,
or binding, and the battery is fully charged and in good condition.
The model is equipped with a Velineon 3500 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 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. For this type of driving, smaller pinion gears are
recommended to reduce load on the motor.

Tuning the Sealed Gear Differentials
The action of the model’s front and rear gear differentials can
be tuned for different driving conditions and performance
requirements, without major disassembly or removal of the
suspension system.
From the factory, the differentials are sealed to maintain consistent
long-term performance. Changing the oil in the differential with
either lower or higher viscosity oil will vary the performance
characteristics of the differentials. Changing to a higher viscosity oil
in the differential will reduce the tendency for motor power to be
transferred to the wheel with the least traction. You may notice this
when making sharp turns on slick surfaces. The unloaded wheels
on the inside of the turn have the least traction and tend to spin
up to extremely high rpms. Higher viscosity (thicker) oil causes the
differential to act like a limited-slip differential, distributing more
equal power to the left and right wheels.
Your model will generally benefit from higher viscosity oil when
racing on low traction surfaces. Note: Heavier oil will allow power to
be transferred even with one or more tires off the ground. This can
make the vehicle more likely to overturn on high-traction surfaces.
From the factory, the front differential is filled with SAE 30,000W
viscosity silicone oil and the rear differential is filled with SAE
10,000W viscosity silicone oil.
Only use silicone oil in the differentials. Traxxas offers SAE 10,000W,
30,000W, and 50,000W viscosity oil (see your parts list). The
differentials have to be removed from the vehicle and disassembled
to change/replace oil.

CHASSIS ADJUSTABILITY
Adjustable Body Mounts
The 4-Tec 2.0 chassis features adjustable body mounts to
accommodate many popular 200mm touring car body styles. To
adjust the mounts forward or backward, simply remove the fixed
screws and install them in the sliding channels. If you need to
adjust for width, remove all four screws and pull the body posts out
sideways. Reinsert the body posts in the opposite direction so that
the screw will pass through the channel. Once you are satisfied with
the positioning, tighten down the screws to secure the mounts. An
optional set of fixed body mounts is also included with your model.
Adjustable Wheelbase
The 4-Tec 2.0 chassis allows you to lengthen or shorten the
wheelbase by up to 3mm for the perfect body fit. Remove the rear
suspension arms from the vehicle and trim material from the front
or rear of the arms. Save the material you remove and add it to the
opposite side of the arms to act as a spacer, or use washers to shim
the arms. Note: The front suspension arms are not adjustable and
should not be modified or trimmed.
26 • TRAXXAS
High-Angle Steering
The steering blocks on the 4-Tec 2.0 chassis feature a high-angle
option when extra steering angle is desired (for example, when
power drifting around a turn). First trim the plastic bump stop
to allow greater range of motion from the steering blocks (see
illustration). Next, drill out the inner hole on the steering block
and move the steering link to the inner hole. When making this
modification, we also recommend that you upgrade to constantvelocity driveshafts (sold separately) to avoid driveshaft chatter.

the use of different bodies.
The lower mounting points
LOWER
should be used with lowMOUNTING
profile bodies; the upper

two holes for wheel camber
adjustment. Moving the links from the standard holes to the outer
holes will increase camber and slightly reduce roll stiffness. This
modification also requires adjustable camber links (part #8341X, sold
separately) to lengthen the links and ensure proper camber settings.
Suspension Droop Adjustment
Suspension droop is the amount of downward travel on the wheels
(how much the suspension arm hangs down when the chassis is
off the ground). Molded screw bosses in the suspension arms allow
you to adjust droop by using a 4mm set screw (part #4897, sold
separately). Tightening the screw will decrease droop and allow you
to tune the suspension for better stability when cornering.

MAINTAINING YOUR MODEL
Always wear eye protection
when using compressed
air or spray cleaners and
lubricants.
Your model requires timely maintenance in order to stay in top
running condition. The following procedures should be taken
very seriously.
Frequently inspect the vehicle for obvious damage or wear. Look
for:
1. Cracked, bent, or damaged parts
2. Check the wheels and steering for binding.
3. Check the operation of the shock absorbers.
4. Check the wiring for any frayed wires or loose connections.
5. Check the mounting of the receiver, servo, and speed control.
6. Check the tightness of the wheel nuts with a wrench.
7. Check the operation of the radio system, especially the
condition of the batteries.
8. Check for any loose screws in the chassis structure or
suspension.
9. Check the operation of the steering servo and ensure that it is not
binding.
10.Inspect the gears for wear, broken teeth, or debris lodged between
the teeth.
Other periodic maintenance:
• Chassis: Keep the chassis clean of accumulated dirt and grime.
Periodically inspect the chassis for damage.
• Suspension: Periodically inspect the model for signs of damage,
such as bent or dirty suspension pins, bent camber links, loose
screws, and any signs of stress or bending. Replace components
as needed.
• Steering: Over time, you may notice increased looseness in
the steering system. Replace any components as needed to restore
factory tolerances.
• Shocks: Keep the oil level in the shocks full. Use only 100%
pure silicone shock oil to prolong the life of the seals. If you are
experiencing leakage around the top of the shock, inspect the
bladder in the top cap for signs of damage or distortion from
overtightening. If the bottom of the shock is leaking, then it is time
for a rebuild. The Traxxas rebuild kit for two shocks is part #2362.

28 • TRAXXAS
• Driveline: Inspect the driveline for signs of wear or any unusual
noise or binding. Remove the gear cover and inspect the spur
gear for wear and check the tightness of the set screw in the
pinion gear. Tighten, clean, or replace components as needed.
Note: When replacing the
spur gear, be sure the spur
gear is fully seated on the
center driveshaft as shown.
There will be an audible
“click” as the gear is pushed
into place.
Storage
When you are through running your model for the day, blow it off
with compressed air or use a soft bristled paint brush to dustoff the vehicle. Always disconnect and remove the battery from
your model whenever the model is stored. If your model will be
stored for a long time, then also remove the batteries from the
transmitter.
TQi ADVANCED TUNING GUIDE
Your Traxxas transmitter has a programmable Multi-Function knob
that can be set to control various advanced transmitter functions (set to
Traxxas Stability Management (TSM) by default, see page 17). Accessing
the programming menu is done by using the menu and set buttons on
the transmitter and observing signals from the LED. An explanation of
the menu structure follows on page 32. Experiment with the settings and
features to see if they can improve your driving experience.
Steering Sensitivity (Exponential)
The Multi-Function knob on the TQi transmitter can be set to control
Steering Sensitivity (also known as exponential). The standard setting
for Steering Sensitivity is “normal (zero exponential),” with the dial full
left in its range of travel. This setting provides linear servo response: the
steering servo’s movement will correspond exactly with the input from
the transmitter’s steering wheel. Turning the knob clockwise from center
will result in “negative exponential” and decrease steering sensitivity by
making the servo less responsive near neutral, with increasing sensitivity as
the servo nears the limits of its travel range. The farther you turn the knob,
the more pronounced the change in steering servo movement will be.
The term “exponential” comes from this effect; the servo’s travel changes
exponentially relative to the input from the steering wheel. The exponential
effect is indicated as a percentage—the greater the percentage, the greater
the effect. The illustrations below show how this works.
Normal Steering Sensitivity (0%
exponential):
In this illustration, the steering
servo’s travel (and with it, the
steering motion of the model’s
front wheels) corresponds
precisely with the steering wheel.
The ranges are exaggerated for
illustrative purposes.
Decreased Steering Sensitivity
(Negative Exponential):
Effective Turning
Turning Range
Range on Model
By turning the Multi-Function
at Transmitter
knob clockwise, the steering
sensitivity of the model will
be decreased. Note that a
relatively large amount of
steering wheel travel results in a
smaller amount of servo travel.
The farther you turn the knob,
the more pronounced the effect
becomes. Decreased steering
sensitivity may be helpful
when driving on low-traction surfaces, when driving at high speed, or on tracks
that favor sweeping turns where gentle steering inputs are required. The ranges are
exaggerated for illustrative purposes.
Throttle Sensitivity (Throttle Exponential)
The Multi-Function knob can be set to control Throttle Sensitivity.
Throttle Sensitivity works the same way as Steering Sensitivity, but
applies the effect to the throttle channel. Only forward throttle is
affected; brake/reverse travel remains linear regardless of the Throttle
Sensitivity setting.
Steering Percentage (Dual-Rate)
The Multi-Function knob can be set to control the amount (percentage)
of servo travel applied to steering. Turning the Multi-Function knob
fully clockwise will deliver maximum steering throw; turning the
knob counterclockwise reduces steering throw (note: turning the dial
counterclockwise to its stop will eliminate all servo travel). Be aware
that the steering End Point settings define the servo’s maximum
steering throw. If you set Steering Percentage to 100% (by turning the
Multi-Function knob fully clockwise), the servo will travel all the way to
its selected end point, but not past it. Many racers set Dual-Rate so they
have only as much steering throw as they need for the track’s tightest
turn, thus making the model easier to drive throughout the rest of the
course. Reducing steering throw can also be useful in making a model
easier to control on high-traction surfaces, and limiting steering output
for oval racing where large amounts of steering travel are not required.
Braking Percentage
The Multi-Function knob may also be set to control the amount of brake
travel applied by the servo in a nitro-powered model. Electric models do
not have a servo-operated brake, but the Braking Percentage function
still operates the same way in electric models. Turning the Multi-Function
knob full clockwise will deliver maximum brake throw; turning the
knob counterclockwise reduces brake throw (Note: Turning the dial
counterclockwise to its stop will eliminate all brake action).
Throttle Trim
Setting the Multi-Function knob to serve as throttle trim will allow you
to adjust the throttle’s neutral position to prevent unwanted brake drag
or throttle application when the transmitter trigger is at neutral.
Note: Your transmitter is equipped with a Throttle Trim Seek mode to
prevent accidental runaways. See the sidebar for more information.
Starting Over:
Restoring Factory Defaults
When programming your
TQi transmitter, you may feel
the need to start over with
a clean slate. Follow these
simple steps to restore the
factory settings:
1. Turn the transmitter off.
2. Hold both MENU and SET.
3. Turn the transmitter on.
4. Release MENU and SET.
The transmitter LED will
blink red.
5. Press SET to clear settings.
The LED will turn solid
green and the transmitter
is restored to default.
Throttle Trim Seek Mode
When the Multi-Function knob is
set to throttle trim, the transmitter
remembers the throttle trim
setting. If the throttle trim knob is
moved from the original setting
while the transmitter is off, or while
the transmitter was used to control
another model, the transmitter
ignores the actual position of
the trim knob. This prevents the
model from accidentally running
away. The LED on the face of the
transmitter will rapidly blink green

TQi ADVANCED TUNING GUIDE
Failsafe
Your Traxxas radio system is
equipped with a built-in failsafe
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.
Steering and Throttle End Points
The TQi transmitter allows you to choose the limit of the servo’s travel
range (or its “end point”) independently for left and right travel (on the
steering channel) and throttle/brake travel (on the throttle channel).
This allows you to fine-tune the servo settings to prevent binding
caused by the servo moving steering or throttle linkages (in the case
of a nitro model) farther than their mechanical limits. The end point
adjustment settings you select will represent what you wish to be the
servo’s maximum travel; the Steering Percentage or Braking Percentage
functions will not override the End Point settings.
Steering and Throttle Sub-Trim
The Sub-Trim function is used to precisely set the neutral point of the
steering or throttle servo in the event that simply setting the trim knob
to “zero” does not completely center the servo. When selected, Sub-Trim
allows finer adjustment to the servo output shaft’s position for precise
setting of the neutral point. Always set the Steering Trim knob to zero
before making final adjustment (if required) using Sub-Trim. If Throttle
Trim has been previously adjusted, the Throttle Trim will need to be
reprogrammed to “zero” before making final adjustment using Sub-Trim.
Setting Lock
Once you’ve adjusted all of these settings the way you like them, you
may want to disable the Multi-Function knob so none of your settings
can be changed. This is especially handy if you operate multiple
vehicles with a single transmitter via Traxxas Link™ Model Memory.
Multiple Settings and the Multi-Function Knob
It is important to note that settings made with the Multi-Function
knob are “overlaid” on top of each other. For example, if you assign the
Multi-Function to adjust Steering Percentage and set it for 50%, then
reassign the knob to control Steering Sensitivity, the transmitter will
“remember” the Steering Percentage setting. Adjustments you make
to Steering Sensitivity will be applied to the 50% steering throw setting
you selected previously. Likewise, setting the Multi-Function knob to
“disabled” will prevent the knob from making further adjustments, but
the last setting of the Multi-Function knob will still apply.

TQi ADVANCED TUNING GUIDE
TRAXXAS LINK MODEL MEMORY
Traxxas Link Model Memory is an exclusive, patent-pending feature
of the TQi transmitter. Each time the transmitter is bound to a new
receiver, it saves that receiver in its memory, along with all the settings
assigned to that receiver. When the transmitter and any bound receiver
are switched on, the transmitter automatically recalls the settings for
that receiver. There is no need to manually select your vehicle from a list
of model memory entries.
Model Lock
The Traxxas Link Model Memory feature can store up to thirty models
(receivers) in its memory. If you bind a thirty-first receiver, Traxxas Link
Model Memory will delete the “oldest” receiver from its memory (in
other words, the model you used the longest time ago will be deleted).
Activating Model Lock will lock the receiver in memory so it cannot be
deleted.
You may also bind multiple TQi transmitters to the same model, making
it possible to pick up any transmitter and any previously bound model
in your collection and simply turn them on and drive. With Traxxas
Link Model Memory, there is no need to remember which transmitter
goes with which model, and there is never a need to have to select any
model from a list of model memory entries. The transmitter and receiver
do it all for you automatically.
To activate Model Lock:
1. Switch on the transmitter and receiver you wish to lock.
2. Press and hold MENU. Release when the status LED blinks green.
3. Press MENU three times. The status LED will blink green four
times repeatedly.
4. Press SET. The status LED will blink green in single-flash intervals.
5. Press SET once. The status LED will blink red once repeatedly.
6. Press MENU once. The status LED will blink red twice repeatedly.
7. Press SET. The LED will blink rapidly green. The memory is now
locked. Press and hold MENU to return to driving mode.
Note: To unlock a memory, press SET twice at step 5. The LED will
blink rapidly green to indicate the model is unlocked. To unlock all
models, press MENU twice at step 6 and then press SET.
To delete a model:
At some point, you may wish to delete a model you no-longer drive
from the memory.
1. Switch on the transmitter and receiver you wish to delete.
2. Press and hold MENU. Release when the status LED blinks green.
3. Press MENU three times. The status LED will blink green four
times repeatedly.
4. Press SET once. The status LED will blink green once repeatedly.
5. Press MENU once. The status LED will blink green twice repeatedly.
6. Press SET. The memory is now selected to be deleted. Press SET to
delete the model. Press and hold MENU to return to driving mode.
