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.

BATTERIES AND BATTERY CHARGING

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 for charging and maintaining the batteries. It is your responsibility
to charge and care for the battery packs properly. In addition to your battery and
charger instructions, here are some more tips to keep in mind.

•

Use the supplied charger to charge the included battery. See “Charging the
Battery Pack” on page 11.

•

Never leave batteries to charge unattended.

•

Remove the battery 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 pack to cool off between runs (before charging).

•

Children should have responsible adult supervision when charging and
handling batteries.

•

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

Recycling Your Traxxas Power Cell NiMH Battery

Traxxas strongly encourages you to recycle your Power Cell battery when it
has reached the end of its useful life. Do not throw your battery in the trash.
All Power Cell battery packs display the RBRC (Rechargeable Battery Recycling
Corporation) icon, indicating they are recyclable. To find a recycling center near
you, ask your local hobby dealer or visit www.call2recycle.org.

LiPo Batteries

Lithium Polymer (LiPo) batteries are becoming popular for use in R/C models due
to their compact size, high energy density, and high-current output. However,
these types of batteries require special care and handling procedures for long
life and safe operation. WARNING: LiPo batteries are intended only for advanced
users that are educated on the risks associated with LiPo battery use. Traxxas does

not recommend that anyone under the age of 16 use or handle LiPo battery
packs without the supervision of a knowledgeable and responsible adult.

Your model is able to use LiPo batteries with nominal voltage not to exceed 11.1
volts (3S packs). LiPo batteries have a minimum safe discharge voltage threshold
that should not be exceeded. The Velineon VXL-3s 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 on the speed control is just one part of a comprehensive
plan for safe LiPo battery use. It is critical for you, the user, to follow all

other instructions supplied by the battery manufacturer and the charger
manufacturer for proper charging, use, and storage of LiPo batteries. Do
not attempt to charge LiPo batteries with the Traxxas charger included in
this package. Make sure you understand how to use your LiPo batteries.

Be aware that Traxxas shall not be liable for any special, indirect, incidental, or
consequential damages arising out of the installation and/or use of LiPo batteries
in Traxxas models. 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.

SPEED CONTROL

• 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.

• Don’t Get Burned: The heat sink can get extremely hot, so be careful not to
touch it until it is cool. Supply adequate airflow for cooling.

• 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 damage
from accidentally mis-wiring the speed control. Please note that modified speed
controls can be subject to a rewiring fee when returned for service. Removing
the battery connector on the speed control or using the same-gender
connectors on the speed control will void the product’s warranty.

• Insulate the Wires: Always insulate exposed or damaged wiring with heat shrink
tubing to prevent short circuits

Applying the Decals

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.

INTRODUCTION

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 compliment 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 Dual
Rate are also available. Many of the next-level features are controlled
by the Multi-Function knob, which can be programmed to control
a variety functions. The detailed instructions (page 26) and Menu
Tree (page 28) 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.

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

RADIO AND POWER SYSTEM TERMINOLOGY

Please take a moment to familiarize yourself with these radio and
power system terms. They will be used throughout this manual.
A detailed explanation of the advanced terminology and features
of your new radio system begins on page 26.

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.

Cogging - Cogging is a condition sometimes associated with

8

brushless motors. Typically it is a slight stutter noticed when
accelerating from a stop. It happens for a very short period as

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 that allows
extremely high energy density and current handling in a
compact size. These are high performance batteries that require
special care and handling. For advanced users only.

mAh – Abbreviation for milliamp hour. A measure of the capacity

of the battery pack. The higher the number, the longer the
battery will last between recharges.

Neutral position - The standing position that the servos seek

when the transmitter controls are at the neutral setting.

NiCad - Abbreviation for nickel-cadmium. The original

rechargeable hobby pack, NiCad batteries have very high

current

handling, high capacity, and can last up to 1000 charging cycles.

TRAXXAS TQi RADIO & VELINEON POWER SYSTEM

Good charging procedures are required to reduce the possibility
of developing a “memory” effect and shortened run times.

NiMH - Abbreviation for nickel-metal hydride. Rechargeable

NiMH batteries offer high current handling, and much greater
resistance to the “memory” effect. NiMH batteries generally
allow higher capacity than NiCad batteries. They can last up to
500 charge cycles. A peak charger designed for NiMH batteries is
required for optimal performance.

Receiver - The radio unit inside your model that receives signals

from the transmitter and relays them to the servos.

Resistance - In an electrical sense, resistance is a measure of how

an object resists or obstructs the flow of current through it.
When flow is constricted, energy is converted to heat and is lost.
The Velineon power system is optimized to reduce electrical
resistance and the resulting power-robbing heat.

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.

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).

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.

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.

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.

IMPORTANT RADIO SYSTEM PRECAUTIONS

• For maximum range, always point the front of transmitter toward
the model.

• Do not kink the receiver’s antenna wire. Kinks in the antenna wire
will reduce range.

• DO NOT CUT any part of the receiver’s antenna wire. Cutting the
antenna 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.

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.

Another convenient option for charging the included battery
is an AC peak-detecting charger that plugs directly into an AC wall
outlet, such as the Traxxas EZ-Peak™ (part #2931) or the Traxxas
EZ-Peak Plus™ (part #2933). These chargers contain special peak­detection circuitry that automatically shuts the charger off when
the battery is fully charged.

For faster charging, the included battery may be charged at 4 amps;
do not charge the battery at a higher setting. At the 4-amp setting,
the Traxxas EZ-Peak Plus™ will charge the included battery in about
45 minutes!

CAUTION: Never use a 15-minute timed charger to recharge your
model’s battery packs. Overcharging may result, causing damage to
the battery packs.

If the power indicator doesn’t
light green, check the polarity
of the batteries. Check
rechargeable batteries for
a full charge. If you see any
other flashing signal from the
LED, refer to the chart on page
27 to identify the code.

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 instructions.

If you use rechargeable
batteries in your
transmitter, be aware
that when they begin
to lose their charge, they lose
power more quickly than
regular alkaline batteries.

Caution: Discontinue running
your model at the first sign of
weak batteries (flashing red
light) to avoid losing control.

battery hold-down with body clips in the holes in the posts. Do not
connect the battery pack yet.

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 Velineon Brushless Power system.

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.

Using Other Batteries

Your model is equipped with a state of the art, high-performance
power system. It is designed to be able to flow large amounts
power with least amount of restriction. The benefits are drastically
increased speed and acceleration; however, this places extra
demands on the battery and electrical system connections. For best
performance, your model requires the use of NiMH battery packs
that have cells rated for high discharge and use high-quality, low­resistance assembly techniques, such as the included Traxxas Power
Cell Battery Pack. Cheaply made battery packs do not retain their
performance characteristics after repeated uses in high-powered
electric applications. They will lose their punch and run time and
may require frequent replacement. In addition, poor-quality,
high-resistance cell connectors could fail, requiring disassembly
and repair. The main goal is to reduce all sources of high
resistance in the pack. This includes the connector, the
wire, and the bars attaching the cells together. High
pack resistance will create additional heat and
rob you of the full power the cells are capable
of producing. We recommend using Traxxas
Power Cell batteries for best performance.

RADIO SYSTEM RULES

• Always turn your TQi transmitter on first and off last. This
procedure will help to prevent your model from receiving stray
signals from another transmitter, or other source, and running
out of control. Your model has electronic fail-safes to prevent this
type of malfunction, but the first, best defense against a runaway
model is to always turn the transmitter on first, and off last.

• Always use new or freshly charged batteries for the radio system.

Weak batteries will limit the radio signal between the receiver
and the transmitter. Loss of the radio signal can cause you to lose

control of your model.

1

Always turn your

transmitter on first.

2

Plug in the battery.

3

Turn on the model.

• In order for the transmitter and receiver to bind to one another,
the receiver in the model must be turned on within 20 seconds
of turning on the transmitter. The transmitter LED will flash fast
red indicating a failure to link. If you miss it, simply turn off the
transmitter and start over.

• Always turn on the transmitter before plugging in the battery.

RADIO SYSTEM BASIC ADJUSTMENTS

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%).

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.

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.

Multi-Function Knob

The Multi-Function knob can be
programmed to control a variety of functions.
From the factory, the Multi-Function knob
controls steering sensitivity, also known as exponential or “expo.”
When the knob is turned counterclockwise all the way to the left
(default position), expo is off and steering sensitivity will be linear
(the most commonly used setting). Turning the knob clockwise will
“add expo” and decrease the steering sensitivity in the initial range
of steering wheel travel left or right from center. For more detail on
steering exponential, refer to page 17.

To change the throttle neutral adjust

Remember, always turn the
TQi transmitter on first and
off last to avoid damage to
your model.

Automatic Fail-Safe

The TQi transmitter and
receiver are equipped with
an automatic fail-safe 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 failsafe activates
while you are operating
your model, determine the
reason for signal loss and
resolve the problem before
operating your model again.

When rechargeable batteries
begin to lose their charge,
they will fade much faster
than alkaline dry cells. Stop
immediately at the first sign
of weak batteries. Never turn
the transmitter off when the
battery pack is plugged
in. The model could run out
of control.

USING THE RADIO SYSTEM

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. With the
transmitter on, press and release the EZ-Set button (.25 seconds).
The LED will shine RED (see note, below). This turns the model
on. To turn the VXL-3s off, press and hold the EZ-Set button
until the LED turns off (.5 seconds). Note: If the LED shines
green, Low-Voltage Detection is activated. This may cause poor
performance from the included NiMH battery pack. The default
factory setting is for Low-Voltage Detection to be disabled
(LED shines red). 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
model, the front wheels
should be pointing
straight ahead. If the
wheels are turned slightly
to the left or right, slowly
adjust the steering trim
control on the transmitter until they are pointing straight ahead.

7.

Gently operate the throttle trigger to ensure that you have
forward and reverse operation, and that the motor stops when
the throttle trigger is at neutral. Warning: Do not apply full

throttle in forward or reverse while the model is elevated.

8. Once adjustments are made, turn off the receiver on your model,
followed by the hand-held transmitter.

0°0°

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 truck’s running
area, not the far end, so you drive the truck towards and past
your position. In addition to maximizing the radio’s range, this
technique will keep your model closer to you, making it easier to
see and control.

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
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.

TRAXXAS TQi RADIO & VELINEON POWER SYSTEM

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.

Steering Sensitivity (Exponential)

The Multi-Function knob on the TQi transmitter has been
programmed 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
the left 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.

on low-traction surfaces, when driving at high speed, or on tracks
that favor sweeping turns where gentle steering inputs are required.

Experiment! Try varying degrees of exponential. It’s easy to go back
to “zero” if you don’t like the effect. There’s no wrong way to adjust
exponential. Any setting that makes you more comfortable with
your model’s handling is the “right setting.”

SETTING UP THE ANTENNA

The receiver antenna has been set
up and installed from the factory.

When reinstalling the antenna, first
slide the antenna wire into bottom
of antenna tube until white tip of
antenna is at top of tube under the
black cap. Next insert the antenna
tube into the mount while making
sure that antenna wire is in slot in
the antenna mount.

Do not bend or
kink the antenna wire! See the side
bar for more information. Do not
shorten the antenna tube.

Decreased Steering Sensitivity (Negative Exponential)

By turning the Multi-Function 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.

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.

Your model includes a Power Cell NiMH battery. The VXL-3s speed control’s
Low Voltage Detection has been disabled for best performance with
this battery. The speed control’s LED will glow red when it is turned on,
indicating Low Voltage Detection is disabled. Be certain to activate Low­Voltage Detection if you install LiPo batteries in your model.

Never use LiPo

batteries while Low-Voltage Detection is disabled.

Verify that Low-Voltage Detection is DISABLED:

1. Turn on the transmitter (with the throttle at neutral).

2. Connect a fully charged battery pack to the 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.

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.

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)

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.

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

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 25).

• 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 (see page 26) 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

9

20 • TRAXX AS

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 battery packs that allow extended periods
of running. Monitoring temperatures will extend the lives of the batteries and
motors. See page 25 for advanced user information on monitoring temperatures.

• 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, sluggish servos (slow to return
to center), or ESC shutdown due to the Low-Voltage Detection circuitry. 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 pinion 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.

• High performance vehicles produce small vibrations which may loosen hardware
over time. Frequently check wheel nuts and other screws on your vehicle to ensure
that all hardware remains properly tightened.

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 and charger.

.

•

Use the correct Low-Voltage Detection setting for your battery (see page 18). Low­Voltage Detection can be off for maximum NiMH battery runtime. Never use LiPo
batteries while Low-Voltage Detection is turned off.

• Keep the VXL-3s cool.

•

Lower your gear ratio. Installing a smaller pinion or larger spur gear will lower your
gear ratio, causing less power draw from the motor and battery, and reducing overall

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.

Get plenty of airflow across the ESC heat sinks.

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. Do not use
LiPo batteries in wet conditions.

• The Traxxas TQi 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).

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

• Velineon motor life can be greatly reduced in mud and water. If the motor gets

excessively wet or submerged, use very light throttle (run the motor slowly) until
the excess water can run out. Applying full throttle to a motor full of water can
cause rapid motor failure. Your driving habits will determine motor life with a
wet motor. Do not submerge the motor under water.

• Do not gear the motor by temperature when running in wet conditions. The

motor will be cooled by water contact and will not give an accurate indication of
appropriate gearing.

After Running Your Vehicle in Wet Conditions

1. Drain the tires by spinning the tires at high speed to “sling” the water out. One way
to do this is to make several high-speed passes on a flat, dry surface, if possible.

2. Remove the batteries.

3. Rinse excess dirt and mud off the truck with low-pressure water, such as from a
garden hose. Do NOT use pressure washer or other high-pressure water. Avoid
directing water into the bearings, transmission, etc.

4. Blow off the truck with compressed air (optional, but recommended). Wear
safety glasses when using compressed air.

5. Remove the wheels from the truck.

6. Spray all the bearings, drivetrain, and fasteners with WD-40

®

or similar water

displacing light oil.

7. Let the truck stand or you may blow off with compressed air. Placing the truck
in a warm sunny spot will aid drying. Trapped water and oil will continue to
drip from the truck for a few hours. Place it on a towel or piece of cardboard to
protect the surface underneath.

8. As a precautionary step, remove the sealed receiver box cover. While unlikely,
humidity or tiny amounts of moisture or condensation may enter the receiver
box during wet running. This can cause long-term problems with the sensitive
electronics in the receiver. Removing the receiver box cover during storage
allows the air inside to dry. This step can improve the 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.

• Velineon motor: Remove the motor, clean with aerosol motor cleaner, and
re-oil the bearings with lightweight motor oil. Be sure to wear eye protection
when using spray aerosol cleaners.

RECEIVER BOX: MAINTAINING A WATERTIGHT SEAL

Removing and Installing Radio Gear

The unique design of the receiver box allows the removal and installation of the
receiver without losing the ability to maintain a watertight seal in the box. The
patent-pending wire clamp feature gives you the ability to also install aftermarket
radio systems and maintain the watertight features of the receiver box.

Removing the Receiver

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

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

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

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

Receiver Installation

1. Install the electronic speed control (ESC), servo, and
antenna wiring through the receiver box top (A). Make
sure the box light pipe is aligned with the receiver LED.

2. Plug ESC and servo wires into the receiver (see page 12).

3. Bundle wiring as necessary.

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

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

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

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

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

9. Install the wire clamp and tighten the two 2.5x8mm cap
screws securely (D).

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

Adjusting Gear Mesh

Incorrect gear mesh is the most common
cause of stripped spur gears. Gear mesh
should be checked and adjusted anytime a

Strip of

Paper

gear is replaced. 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 spur gear. Retighten the

Motor

Screws

motor screws and then remove the strip
of paper. You should be able to run a fresh
strip of paper through the gears without binding them.

Adjusting the Toe-in

Geometry and alignment specs play an important roll in your
model’s handling. Take the time to set them correctly. Set the
steering trim on your transmitter to neutral. Now, adjust your servo
and tie rods so that both wheels are pointing straight ahead and are
parallel to each other (0-degrees toe-in). This will ensure the same
amount of steering in both directions.

1°-2

to 2 degrees of negative camber. These adjustments should be set with
the truck positioned at its normal ride height.

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

Pre-load

Spacer

the same damping as a three-hole piston
with heavier oil. We recommend using the
two-hole pistons with a range of oil viscosities
from 10W to 50W (available from your hobby
shop). The thinner viscosity oils (30W or less)
flow more smoothly and are more consistent,
while thicker oils provide more damping. Use
only 100% pure silicone shock oil to prolong seal life. The model’s
ride height can be adjusted by adding or removing the clip-on,
spring pre-load spacers. Adjust the ride height so that the suspension
arms are slightly above being parallel to the ground. Observe how
the model handles in turns. Proper set-up will add stability and help
prevent spin outs. Experiment with different springs and shock oils to
find what works best for your current track conditions.

Wheels and Tires

Toe-in

For increased stability add one- to two-degrees of toe in to each
front wheel. Use the turnbuckles to adjust the alignment.

Adjusting the Camber

The camber angle of

(wheel perpendicular to the ground). In the rear, adjust the wheels to 1

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

BASIC TUNING ADJUSTMENTS

hard, dry surfaces. In loose dirt, a tire with large spikes should
perform better. See your parts list for accessory wheels and tires.

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

Tighten

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 high­traction surface, such as carpet. Adjust the slipper so that you can
hear it slip for approximately two feet from a standing, full throttle
start. (Learn more about adjusting the slipper clutch in the sidebar.)

Centering Your Servo

If you have removed the servo horn from your model’s steering
servo, or the servo has been removed for service or cleaning, the
servo must be re-centered prior to installation of the servo horn or
installation of the servo in the model.

1. Remove 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 receiver’s LED.

3. Turn the transmitter power switch on. Make certain the
transmitter’s batteries are not depleted.

4. Turn the transmitter’s steering trim knob to the center “0”
position.

5. Disconnect motor wires “A” and “C” (see page 12) to prevent the
motor from turning during the next steps. Connect a fresh battery
pack to the speed control and turn on the ESC (see page 15). The
servo’s output shaft will automatically jump to its center position.

6. Install the servo horn onto the servo output shaft. The servo horn
should face toward the center of the chassis and be perpendicular
to the servo body.

7. 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. Use the transmitter’s
steering trim knob to fine-tune the position of the servo horn so
the model tracks straight when the steering wheel is at neutral.

MAINTAINING YOUR MODEL

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

High performance vehicles
generate small vibrations
while driving. These
vibrations may loosen
hardware over time and
require attention. Always
check your wheel nuts and
other hardware and tighten
or replace when necessary.

Always use the proper length
motor bolts. The standard
motor mounting bolts
are 3x8mm. Using motor
bolts that are too long can
interfere with the motor’s
rotation and damage the
motor’s internals!

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 and servo(s) and
speed control.

6. Check the tightness of the wheel nuts with a wrench.

7. Check the operation of the radio system, especially the
condition of the batteries.

8. Check for any loose screws in the chassis structure
or suspension.

9. The steering servo saver will wear out over time. If the steering
becomes loose, the servo saver should be replaced.

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

11. Check the tightness of the slipper clutch.

Other periodic maintenance:

• Slipper clutch pads

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

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

Periodically inspect the chassis for damage

• Steering: Over time, you may notice increased looseness in the
steering system. There are several components that will wear
out from use: the servo saver, the tie rod ends, and the bellcrank
bushings (Rustler and Bandit only). Replace these components as
needed to restore factory tolerances. The bell crank bushings may
be replaced with 5x8mm ball bearings. See the parts list included
with your model for replacement part number

• 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.

Storage

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

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

ADVANCED TUNING ADJUSTMENTS

Gearing

One of the more significant advantages to your model’s transmission
is the extremely wide range of available gear ratios. Changing the
gearing allows you to fine tune the speed of the model and control
the temperatures of the battery pack and motor. Use a lower gear
ratio (numerically larger) to reduce current draw and temperatures.
Use a higher gear (numerically lower) to increase top speed. 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

When using higher gear ratios, it is important to monitor the
temperatures of the battery and motor. If the battery is extremely
hot, and/or the motor is too hot to touch, your model is probably
over-geared and drawing too much current. 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. Note: Check and
adjust gear mesh if a spur and/or pinion gear is changed.

This 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 install the
included optional large pinion gear (more teeth). The included

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

TQi ADVANCED TUNING GUIDE

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 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.

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
and the throttle trim knob (Multi­Function knob) will not adjust the
trim until it is moved back to its
original position saved in memory.
To restore throttle trim control,
simply turn the multi-function
knob either direction until the LED
stops blinking.

26 • TRAXX AS

Your Traxxas transmitter has a programmable

Multi-Function knob
that can be set to control various advanced transmitter functions (set to
Steering Sensitivity 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 28. Experiment with the settings and features to see if
they can improve your driving experience.

Throttle Sensitivity (Throttle Exponential)

The Multi-Function knob can be set to control Throttle Sensitivity.
Throttle Sensitivity works the same way as Steering Sensitivity as
described on page 17, 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
counter-clockwise reduces steering throw (note: turning the dial
counter-clockwise 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
counter-clockwise 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.

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.

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 twenty models
(receivers) in its memory. If you bind a twenty-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 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 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.
