LiPo Batteries
Lithium Polymer (LiPo) batteries are becoming popular for use in R/C models
due to their compact size, high energy density, and high-current output;
however, these types of batteries require special care and handling procedures
for long life and safe operation. Warning:LiPo batteries are intended only for
advanced users that are educated on the risks associated with LiPo battery
use. Traxxas does not recommend that anyone under the age of 14 use or
handle LiPo battery packs without the supervision of a knowledgeable and
responsible adult.
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-3m 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.
DO NOT ATTEMPT TO CHARGE LIPO BATTERIES OR ANY OTHER TYPE OF
BATTERY WITH THE INCLUDED TRAXXAS CHARGER.
If you have questions about LiPo battery usage, please consult with your local
hobby dealer or contact the battery manufacturer.
Recycling Your Traxxas Power Cell NiMH Battery
Traxxas strongly encourages you to recycle your Power Cell NiMH battery
when it has reached the end of its useful life. Do not throw your battery in
the trash. All Power Cell NiMH battery packs display the RBRC (Rechargeable
Battery Recycling Corporation) icon, indicating they are recyclable. To
find a recycling center near you, ask your local hobby dealer or visit www.

Speed Control
• Disconnect the Battery: Always disconnect the battery 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 connectors with no reverse-polarity
protection 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.
• No Reverse Voltage: The speed control is not protected against reverse
polarity voltage. When changing the battery and/or motor, be sure to
install the same type of connectors to avoid reverse polarity damage
to the speed control. Removing the battery connectors on the speed
control or using the same-gender connectors on the speed control will
void the product’s warranty.
• No Schottky Diodes: External Schottky diodes are not compatible
with reversing speed controls. Using a Schottky diode will damage the
electronic speed control and void the 30-day warranty.

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 TQ 2.4GHz system
automatically selects and locks onto an open frequency, offering
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
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
kV Rating - Brushless motors are often rated by their kV number.

eliminate cogging.
electronics, usually measured in amps. If you look at wire like a
garden hose, current is a measure of how much water is flowing
through the hose.

controls use power more efficiently than mechanical speed
controls so that the battery runs longer. An electronic speed
control also has circuitry that prevents loss of steering and
throttle control as the battery loses its charge.
send signals to your model.
direct-sequence spread spectrum.
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.

battery will last between recharges.
when the transmitter controls are at the neutral setting.
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.
This model operates on the 2.4GHz
Page 9
TRAXXAS TQi RADIO & VELINEON POWER 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. Traxxas power systems are 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.
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.
Servo - Small motor unit in your model that operates the
steering mechanism.
Transmitter - The hand-held radio unit that sends throttle and
steering instructions to your model.
Trim - The fine-tuning adjustment of the neutral position of the
servos, made by adjusting the steering trim knob on the face of
the transmitter.
Thermal Shutdown Protection - Temperature sensing electronics
used in the 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
• 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.
• You must extend the antenna wire in the model as far as possible
for maximum range. In doing so, the antenna wire will be extended
outside of the vehicle body. Do not wrap or coil the antenna wire
to keep it from extending out of the body.
• The antenna wire must be installed into the antenna tube to
protect it from getting cut or damaged, which will reduce range.
When installing the antenna wire into the antenna tube, be careful
not to kink the wire by pressing it against the antenna tube cap.
The antenna wire should extend to just below or to within one-half
inch below the cap.
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.

INSTALLING THE BATTERY PACK
Your model includes a 7.2-volt battery pack. To properly balance themodel, it should be installed in the battery compartment on the leftside of the model. Follow these steps to install the battery:
Battery Installation
1.Open the battery
compartment door by pressingon the release tabs.
2. Install the battery pack with
the battery wires facing therear of the model.
3.Route the battery wire through
the slot near the vent.
4.Close the battery door, making
sure not to pinch the battery
wires. Be sure both release tabs
arefully engaged with the door. Do not connect the battery pack to
the ESC at this time. Note: Always unplug the battery and remove
from the model after use.
Battery Wire Slot
Battery Orientation
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
VXL-3m. 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.
Using LiPo Packs in Your Model
The VXL-3m is compatible with 2S and 3S LiPo packs, and is equipped
with Low-Voltage Detection circuitry to prevent over-discharging.
Make certain LiPo mode is selected (see page 17 for details) when
using LiPo packs in your model.
Using an Additional Power Cell Series 1 NiMH Battery For
Increased Speed
An additional Power Cell Series 1 NiMH battery may also be used to
increase the top speed of your model to 50+mph by connecting the
batteries in series using a Traxxas series connector (part #3063, sold
separately). This also requires a gearing change as described on page 23.
Note: LiPo battery packs should NOT be used with a Traxxas series
connector.
50+mph Battery and Gearing Installation Instructions
1. Install the included high-speed pinion gear as described in Pinion
Gear Installation Instructions on page 23. Install the supplied battery
as described on this page.
2. Install an identical Power Cell Series 1 NiMH battery in the opposite
battery compartment.
3. Plug both batteries into the Y-harness (sold separately). The
harness connects the two packs in series. The two 7.2-volt 6-cell
battery packs will operate as one 14.4-volt 12-cell battery pack.
4. Plug the Y-harness into the speed control.
Precautions
• The High Speed dual-battery configuration is for high-speed
running on smooth surfaces only. Avoid repetitive hard acceleration
to prevent overstressing the motor, speed control, and batteries.
• Make certain both batteries are fully charged before installing them in
your model. Installing a fully charged pack and a partially discharged
pack may lead to overdischarging and damage to the partially
discharged battery.
• Do not mix batteries of different brands, chemistries, or capacities. Only
genuine Traxxas batteries are approved for dual-battery use in this model.
• Stop running your model and allow it to cool if the speed control’s thermal
overload protection activates or if the motor temperature exceeds 200°F.
Page 13
TRAXXAS TQi RADIO & VELINEON POWER SYSTEM
Using an Additional Battery for Increased Run Time
Your model only requires one battery pack, but the chassis can accept
two batteries. Your model can be run with two battery packs to
extend run time. The batteries must be connected in parallel, which
will combine the capacity of the two batteries (for example, two 7.2volt 1000mAh packs connected in parallel will deliver a total capacity
of 2000mAh, but total voltage will remain 7.2 volts). This is easily done
with a parallel Y-harness (Part #3064, sold separately). Be sure to only
use the Y-harness with identical battery packs; do not mix batteries of
different chemistries or capacities.
When operating your model with two batteries, be careful
to monitor the temperature of the speed control and motor
to prevent overheating. Stop running your model and allow
it to cool if the speed control’s thermal overload protection
activates or if the motor temperature exceeds 200°F.
For best off-road handling with two battery packs, consider
installing stiffer springs on your model. Traxxas offers
accessory springs for this purpose; see the parts list included
with your model for part numbers.
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 failsafes 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 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.
• 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.

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
16 for instructions.
To change the throttle neutral adjust
Make certain the model’s
receiver antenna is properly
installed before operating
your model. See “Installing
the Receiver Antenna.”
Failure to properly install the
receiver antenna will result in
greatly reduced radio range
and potential loss of control.
Remember, always turn the
transmitter on first and off
last to avoid damage to your
model.
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.

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 15 for TSM
adjustments.
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 15.
USING THE RADIO SYSTEM
The TQi Radio System has been adjusted at the factory for correct
operation with your model. The adjustment should be checked before
running the model, in case of movement during shipping. Here’s how:
1. Turn the transmitter switch on. The status LED on the transmitter
should be solid green (not flashing).
Elevate the model on a block or a stand so that all the tires are
2.
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-3m off, press and hold the EZ-Set button until
the LED turns off (.5 seconds). Note: If the LED shines green, LowVoltage 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 17 for more information.
5.
Turn the steering wheel on the transmitter back and forth and
check for rapid operation of the steering servo. Also, check that
the steering mechanism is not loose or binding. If the steering
operates slowly, check for weak batteries.
6.
When looking down at the model, the front wheels should be
pointing straight ahead. If the wheels are turned slightly to the
left or right, turn off TSM
(see page 15) 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.
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 top speeds, models can cover anywhere
between 50 to 100 feet every second! It’s a thrill, but use caution to
keep your model in range. If you want to see your model achieve its
maximum speed, it is best to position yourself in the middle of the
truck’s running area, not the far end, so you drive the truck towards
and past your position. In addition to maximizing the radio’s range,
this technique will keep your model closer to you, making it easier
to see and control.
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.
Page 15
TRAXXAS TQi RADIO & VELINEON POWER SYSTEM
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.
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 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 setting
recommended (default) setting
for TSM is to rotate the knob to
the 12:00 position (the zero mark
on the dial).
Turn the knob clockwise to
increase assistance; turn the
knob counterclockwise to
decrease assistance. Turn the
knob counterclockwise to its
Decrease
assistance
Increase
assistance
stop to turn TSM completely off.
Note: TSM is deactivated
TSM off
automatically when driving or
braking in reverse.
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.
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 fail-safe
mode is activated. If FailSafe activates while you
are operating your model,
determine the reason for
signal loss and resolve the
problem before operating
your model again.

Low-Voltage Protection. When the
battery voltage begins to reach the
minimum recommended discharge
voltage threshold for LiPo battery packs,
the VXL-3m will limit the power output
to 50% throttle. When the battery
voltage attempts to fall below the
minimum threshold, the VXL-3m will
shut down all motor output. The LED on
the speed control will slowly blink red,
indicating a low-voltage shutdown. The
VXL-3m will stay in this mode until a fully
charged battery is connected.
Alternating; Blinks Red then Green: If
the motor has no power, the VXL-3m
has entered Over Voltage Protection.
If a battery with too high voltage is
used, the VXL-3m will go into a fail-safe

approximately 20 volts, the ESC may be
damaged. Maximum peak input voltage
limits are 12.6V in LiPo Mode (see page
17) and 18V in NiMH Mode.
The electronic speed control is factory set and should not require any
adjustments. These instructions are provided for your reference.
Setup Programming (Calibrating your ESC and transmitter)
Read through all of the following programming steps before you begin.
If you get lost during programming or receive unexpected results,
simply unplug the battery, wait a few seconds, plug the battery back in,
and start over.
1. Disconnect each of the motor wiresbetween the ESC and the motor.
This is a precaution to prevent runaway when the speed control is
turned on before it is programmed.
2. Connect a fully chargedbattery pack to the ESC.

2. Apply forward throttle. The LED will turn off until full throttle power is
reached. At full throttle, the led will shine RED.
3. Move the trigger forward to apply the brakes. Note that braking
control is fully proportional. The LED will turn off until full braking
power is reached. At full brakes, the LED will shine RED.
4. Return the throttle trigger to neutral. The LED will shine RED.
5. Move the throttle trigger forward again to engage reverse (Profile #1).
The LED will turn off. Once full reverse power is reached, the LED will
shine RED.
6. To stop, return the throttle trigger to neutral.
7. To turn the ESC off, press the EZ-Set button until the RED LED
turns off.

VXL-3m Thermal Shutdown Protection
The VXL-3m is also equipped with thermal shutdown protection. If the
operating temperature exceeds safe limits, the ESC will reduce power
to 50% and the LED will flash red. Additional heating will cause the
speed control to shut down completely until it reaches a safe operating
temperature. Traxxas encourages you to stop driving as soon as the
thermal overload protection is activated.
ESC Profile Selection
The speed control is factory set to Profile #1. To change the profile,
follow the steps described on the next page. The speed control should
be connected to the receiver and battery, and the transmitter should be

LiPo Battery Mode with Low-Voltage Detection
The VXL-3m ESC is equipped with built-in Low-Voltage Detection
for safe use with Lithium Polymer (LiPo) batteries. 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-3m will limit the
power output to 50% throttle. When the battery voltage attempts to
fall below the minimum threshold, the VXL-3m will shut down all motor
output. The LED on the speed control will slowly blink red, indicating a
low-voltage shutdown. The VXL-3m will stay in this mode until a fully
charged battery is connected. The electronic speed control is factory
set with Low-Voltage Detection disabled. Be certain to activate Low-
Voltage Detection if you install LiPo batteries in your model.
To activate Low-Voltage Detection (LiPo setting):
1. Make sure the LED on the ESC 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 ESC 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.
Never use LiPo batteries while Low-Voltage Detection is disabled.
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

(Sport Mode) as the default.
To quickly change to Profile 3
(Training Mode), with the
transmitter on and the ESC
turned off, press and hold
the SET button until the light
blinks red three times and
then release. For full power,
turn off the ESC then quickly
change back to Profile 1 (Sport

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 battery packs that
allow extended periods of running. Monitoring temperatures will
extend the lives of the battery 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.
•
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 2000 mAh battery pack will theoretically
run twice as long as a 1000 mAh 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 the included charger or a high-quality peak-detecting charger.
•
Read and follow all maintenance and care instructions provided by
the manufacturer of your batteries and charger.
• Keep the ESC cool.
•
Lower your gear ratio. Installing smaller pinion gears will lower your
gear ratio and cause less power draw from the motor and batteries,
and reduce overall operating temperatures.
•
Maintain your model. Do not allow dirt or damaged parts to cause
binding in the drivetrain. Keep the motor clean.
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.
Get plenty of airflow across the ESC heat sinks.
RUNNING IN WET CONDITIONS
Your 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 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.
10
18 • 1/16 SUMMIT VXL
Page 19
•
Not all batteries can be used in wet environments. Consult your
battery manufacturer to see if their batteries can be used in
wet conditions.
•
The Traxxas TQ 2.4GHz transmitter is not water resistant. Do not
subject it to wet conditions such as rain.
•
Do NOT operate your model during a rain storm or other inclement
weather where lightning may be present.
•
Do NOT allow your model to come in contact with salt water (ocean
water), brackish water (between fresh water and ocean water), or
other contaminated water. Salt water is highly conductive and highly
corrosive. Use caution if you plan to run your model on or near a beach.
•
Even casual water contact can reduce the life of your motor. Special
care must be taken to modify your gearing and/or your driving style
in wet conditions to extend the life of the motor (details below).
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 (4mm or 3/16” 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) 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
•
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.
DRIVING YOUR MODEL
•
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 full throttle to “sling” the water
out. An easy way to do this is to remove the body and set the truck
upside down on a flat surface. Apply full throttle so the tires spin and
throw the excess water out of the holes you cut into the tires.
2. Remove the battery.
3. Rinse excess dirt and mud off the truck with low-pressure water, such
as from a garden hose. Do NOT use a pressure washer or other highpressure water. Avoid directing water into the bearings, transmission,
differentials, etc.

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.
• Front and rear differential: Remove, disassemble, clean, and regrease the differentials. Refer to your exploded view diagrams for
help with disassembly and reassembly.

TUNING ADJUSTMENTS
Your model is factory-tuned for optimum performance in a
wide variety of off-road conditions. To tailor the performance
and handling of your model to suit your driving style and terrain,
the model has a number of adjustable features. Gearing, shock
preload and damping, ride height, and wheel camber can all be
easily adjusted.
SUSPENSION TUNING
Ride Height Adjustment
Your model has threaded
shock bodies that make it
easy to adjust ride height.
Threading the shocks’
preload collars away from
the caps will raise the
vehicle’s ride height (the
distance from the chassis
to the ground), and
reduce the suspension’s
down travel, also known
Kompression 2/3
Durchbiegung
(Auslenkung) 1/3
Achsmittellinie bei max. Kompression
Achsmittellinie bei Fahrhöhe
Achsmittellinie bei max. Auslenkung
as ‘sag’ or ‘droop’. This
can be helpful in rugged
terrain where extra
ground clearance is needed. However, the vehicle’s center of
gravity (CG) will be raised, making it less stable.
Threading the shocks’ preload collars toward the caps will lower
the vehicle’s ride height and increase the suspension’s droop. This
will lower the vehicle’s CG and improve handling, but it will also
reduce ground clearance.
From the factory, your model is set up as shown in the illustration
above. At rest, the suspension sags to about 1/3 of its total travel.
This allows the suspension to extend so the wheel can drop
into depressions over rough terrain. This leaves 2/3 of the total
suspension travel for compression when absorbing bumps and
landing jumps. These settings are ideal for most surfaces, and only
small changes in ride height should be required to fine-tune the
vehicle’s handling for your particular surface.
Gesamtbewegung
Fahrhöhe
Shock Oil
The 4 oil-filled shocks (dampers) effectively control the suspension
movement by preventing the wheels and tires from continuing
to “bounce” after rebounding from a bump. Changing the oil in
the shocks can vary the suspension damping effect. Changing
the oil to a higher viscosity oil will increase damping. Lowering
the viscosity of the oil will cause the suspension damping to be
reduced. Damping should be increased (with higher viscosity oil)
if the model is bottoming easily over jumps. Damping should
be decreased (with thinner viscosity oil) if the model is hopping
over small bumps and feels unstable. The viscosity of shock oil is
affected by extremes in operating temperature; an oil of certain
viscosity will become less viscous at higher temperatures and more
viscous at lower temperatures. Operating in regions with cold
temperatures may require lower viscosity oil. Your model’s shocks
are filled with SAE 60W oil. Only use 100% silicone oil in the shock.
Replacing Shock Oil
The shocks have to be removed from the vehicle and disassembled
to change the oil.
1. Remove the lower spring retainer and shock spring.
2. Remove the upper
shock cap. If you cannot
unscrew the cap with
your fingers, pass the
2mm ‘L’ wrench through
the cap’s eyelet so
you can apply more
leverage. Turn the cap
counterclockwise to loosen it.
3. Empty the used shock oil from the shock body.
4. Fill the shock with new silicone shock oil up to the top of the
shock body.
5. Slowly move the piston up and down (always keeping it
submerged in oil) to release the air bubbles. Let the shock sit for
a few minutes to allow any remaining air bubbles to surface.
6. Slowly thread the upper cap with the installed shock bladder
onto the shock body. The excess oil will bleed out of the small
hole in the shock cap.
7. Tighten the shock cap until snug.
Important: The shocks are
assembled at the factory with
a center-to-center distance
(between the rod end balls)
of 47.75mm. Any time the
shocks are removed and
disassembled, this distance
should be checked to ensure
proper operation of the
suspension.

TUNING ADJUSTMENTS
A camber gauge (available
at your local hobby shop)
can be a useful tool for
alignment setting.
To achieve a good starting
point for the slipper clutch,
tighten the slipper clutch
adjusting nut clockwise until
the slipper clutch adjusting
spring fully collapses (do
not over tighten), and then
turn the slipper clutch nut
counterclockwise ¾ to 1 turn.
Static Camber Adjustment
The wheels can be set to have either
positive or negative camber (see
illustration below). The camber angle
changes as the wheel moves up and
down through its range of travel. Static
camber is the camber angle at the
wheel when the vehicle is set at its
normal, stationary ride height.
The suspension pivot balls located in the axle carriers adjust the
static camber. Camber is factory-set at -1°, with the pivot balls
threaded all the way into the suspension arms. To adjust static
camber, insert the supplied 2mm hex wrench into the pivot ball
(compressing the suspension until the arms are parallel to the
ground will allow for easier hex wrench engagement). Negative
camber can be increased by unthreading the lower pivot ball. Zero
camber or positive camber (not recommended) can be achieved
by unthreading the upper pivot ball. Note that camber changes
will also effect the toe angle of the wheel being adjusted.

TRANSMISSION TUNING
Adjusting the Slipper Clutch
Your model is equipped with an
adjustable Torque Control slipper
clutch, which is built into the large
spur gear. The purpose of the
slipper clutch is to prevent overstressing of the drivetrain and
transmission gears. It may also be
used to regulate the amount of power sent to the rear wheels to
prevent tire spin. When it slips, the slipper clutch makes a highpitch, whining noise.
To adjust the slipper clutch, remove the receiver box cover.
The slipper clutch is integrated into the main spur gear on the
transmission. The slipper clutch is adjusted using the springloaded locknut on the slipper shaft. Use the supplied universal
wrench. To tighten or loosen the slipper nut, insert the 1.5mm
hex wrench into the hole in the end of the slipper shaft. This locks
the shaft for adjustments. Turn the adjustment nut clockwise to
tighten (less slippage) and counterclockwise to loosen
(more slippage).
Tuning the Sealed Gear Differentials
Your model’s front and rear gear differentials allow the left and
right wheels to spin at different speeds while turning so that the
tires do not scuff or skid. This decreases the turning radius and
increases steering performance.
The performance of the differentials can be tuned for different
driving conditions and performance requirements. The
differentials are filled with silicone differential fluid, and 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 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
22 • 1/16 SUMMIT VXL
Page 23
TUNING ADJUSTMENTS
wheels. Your model will generally benefit from higher viscosity oil
when climbing, rock crawling, or racing on low-traction surfaces.
From the factory, both the differentials are filled with SAE
30,000W viscosity silicone oil. This fluid gives the 1/16 Summit VXL
versatile multi-terrain handling and allows forgiving cornering
on pavement and other high-grip surfaces. For extreme offroad terrain, the differentials may be filled with thicker fluid to
increase traction, at the expense of high-speed cornering stability.
100,000W fluid is a good starting point for extreme-terrain use;
500,000W fluid will virtually lock the differentials. The differentials
must be removed from the vehicle and disassembled to change/
replace oil. Only use silicone oil in the differentials. Traxxas sells a
variety of oil viscosities (see your parts list). 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.
MOTOR AND GEARING
Extensive testing has been done to determine the best gear ratio
for your model. The stock gearing balances power, speed, and
efficiency to optimize the performance of the model. However,
you may wish to try different gear ratios in order to customize the
performance of your model. The gearing chart on this page shows
appropriate gearing for the model.
By installing a pinion with fewer teeth, or a spur gear with
more teeth, the transmission’s final drive ratio is increased.
This means greater rpm is required to achieve a given speed.
Using a numerically higher gear ratio will increase torque, but
reduce top speed. Installing a pinion with more teeth, or a spur
gear with fewer teeth, will decrease the final drive ratio, which
will generally increase top speed but reduce torque. However,
installing too large a pinion will “overgear” the model, which will
reduce performance and may overheat the motor and speed
control. Use the following formula to calculate the overall ratio for
combinations not listed on the gear chart:
# Spur Gear Teeth
# Pinion Gear Teeth
x 5.04 = Final Gear Ratio
Motor Installation
To access the motor, remove the gear cover by removing the single screw on the top of the gear cover. The motor uses an
aluminum mount
for quick, easy motor access and gearing
adjustment. To remove the motor, first
Motor Mount Positions
open the right battery door and slide out
the ESC. Next, remove the single large hex
screw using the supplied 2.5mm wrench.
Then rotate the motor and mount to the
side of the model, and slide backward off
the post.
The motor mount was carefully
engineered to provideadditional features
and adjustability. Two sets of holes

are provided for use with brushed and
brushless motors. The holes for brushed motors are spaced 16mm
apart and accept 2.5mm screws. The holes for brushless motors are
spaced 19mm apart and accept 3mm screws.
Pinion Gear Installation Instructions
1. Remove the motor as described
in Motor Installation.
2. Use a1.5mm wrench to loosen the
pinion’s set screw. Remove the pinion.
3. Place the replacement pinion gear onto
the motor shaft. Align the set screw hole
with the flat side of the shaft.
4. Thread a 1.5mm set screw into the
pinion gear but do nottighten it yet.
5. Slide the pinion gear down the motor shaft so the wrench shaft
fits into the notch in the motor mount, as shown. Tighten the
set screw.

Do Not Loosen
WHEELS AND TIRES
Your model uses 12mm axle hexes that allow many types of
aftermarket tires and wheels to 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.
Experimentation with different types of tires is recommended
to see which ones work the best on the terrain where the model
is run. Soft compound tires with many short spikes generally
work better on hard, dry surfaces. In loose dirt, a tire with large
spikes should perform better. Foam tires can be fitted for use on
pavement or indoor carpet tracks. See your parts list for accessory
wheels and tires.
When selecting tires, consider the overall diameter of the tire.
If the overall diameter is significantly larger than the stock tire’s
diameter, you will need to use a smaller pinion gear to compensate
for the larger tire. If you wish to install tires with a diameter greater
than 4 inches or 100mm, Traxxas suggests you configure the
transmission for ‘underdrive’ gearing. Details on making this simple
modification are available at Traxxas.com.

MAINTAINING YOUR MODEL
Your model requires timely maintenance in order to stay in top
running condition. The following procedures should be taken
very seriously.
Inspect the vehicle for obvious damage or wear. Look for:
1. Cracked, bent, or damaged parts
2. Check the wheels and steering for binding.
3. Check the operation of the shock absorbers.
4. Check the wiring for any frayed wires or loose connections.
5. Check the mounting of the receiver and servo(s) and
speed control.
6. Check the tightness of the wheel nuts with a wrench.
7. Check the operation of the radio system, especially the
condition of the batteries.
8. Check for any loose screws in the chassis structure
or suspension.
9. Inspect the gears for wear, broken teeth, or debris lodged
between the teeth.
10. Check the tightness of the slipper clutch.
11. Check the tightness of the front pivot balls.
Other periodic maintenance:
• Slipper clutch pad (friction material):
Under normal use, the
friction material in the
slipper clutch should
wear very slowly. If
the slipper clutch fails
to provide consistent
performance or slips even
when the adjustment nut is fully
tightened, disassemble the slipper
clutch and replace the slipper pad. Inspect
the spur gear and pressure plate for wear or
damage and replace if necessary.
• Chassis: Keep the chassis clean of accumulated dirt and grime.
Periodically inspect the chassis for damage.
Slipper
Pad
• 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 #7062.
• 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. 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.

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
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 • 1/16 SUMMIT VXL
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 15). 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 29. 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 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):
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.
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. 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.

By

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 MultiFunction 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 hightraction 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 counter-clockwise 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.
Page 27
TQi ADVANCED TUNING GUIDE
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
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
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.

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.

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.

The Menu Tree below shows how to navigate through
the TQi transmitter’s various settings and functions.
Press and hold MENU to enter the Menu Tree, and use

Echo will “play back” your current position on the
Menu Tree should you lose your place. For example:
If your current position is Steering Channel End

twice, green once, and then red three times. Echo
will not alter your adjustments or change your
position in the programming sequence.
Below is an example of how to access a function in the Menu
Tree. In the example, the user is setting the Multi-Function knob

intervals.
3. Press SET. The red LED will blink in single intervals to indicate Steering
Sensitivity (Expo) has been selected.
4. Press MENU twice. The red LED will blink three times repeatedly to
indicate Steering % (Dual-Rate) has been selected.
