SAFETY PRECAUTIONS

All of us at Traxxas want you to safely enjoy your new model. Operate
your model sensibly and with care, and it will be exciting, safe, and fun for
you and those around you. Failure to operate your model in a safe and
responsible manner may result in property damage and serious injury.
The precautions outlined in this manual should be strictly followed to
help ensure safe operation. You alone must see that the instructions are
followed and the precautions are adhered to.

IMPORTANT POINTS TO REMEMBER

• Do not drive your model at night.

• Never, under any circumstances, operate your model in any water where
people are swimming or wading. Your model is fast and could cause
injury if allowed to collide with anyone. Avoid running in areas reserved
for water fowl!

• 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 loss of radio control, always allow a safety margin in
all directions around the boat in order to prevent collisions.

• Do not reach underneath the rear of your model. The propeller could spin
unexpectedly. Always pick up the boat from the front or the side.

• Because of the many dangers involved with any body of water, Traxxas
recommends that you never try to wade or swim to retrieve the boat.
Another section in this manual outlines safer, alternative methods for
boat retrieval.

• Due to the high-performance nature of the electric motor, it can become
extremely hot during use. Do not touch the motor when installing and
removing battery packs.

• Most importantly, use good, common sense when you are around the

water to avoid mishaps such as slipping on a muddy bank. Always
observe water safety rules and regulations.

SPEED CONTROL

• No Brakes: The VXL-6s Marine speed control is not equipped with brakes
and should not be used in land-based vehicles.

• Disconnect the Batteries: Always disconnect the battery packs from the
speed control when not in use.

• Transmitter on First: Switch on your transmitter first before plugging in the
speed control to prevent runaways and erratic performance.

• Always Water Cooling: A silicone water-cooling jacket has been installed
on the motor and the speed control is cooled by water running through
the installed tubing. Never operate your model without these cooling
systems intact. When operating your boat, be certain a steady stream of
water is coming from the water outlet while the boat is running at speed.

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

BATTERIES AND 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 that were provided with your battery packs and your charger. It
is your responsibility to charge and care for your battery packs properly. In
addition to your battery and charger instructions, here are some more tips to
keep in mind.

• Never leave batteries to charge unattended.

• Remove the batteries from the model while charging.

• Always unplug the batteries from the electronic speed control when the
model is not in use and when it is being stored or transported.

• Allow the battery packs to cool off between runs (before charging).

• 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
damaged connector.

• Only use approved chargers for NiMH battery packs (such as the Traxxas
EZ-Peak™ Charger, Part #2930). Do not exceed the maximum charge rate
of 4 amps.

• Do not short-circuit the battery pack. This may cause burns and severe
damage to the battery pack.

• Do not burn or puncture the batteries. Toxic materials could be released.
If eye or skin contact occurs, flush with water.

• Store the battery pack in a dry location, away from heat sources and
direct sunlight.

• Nickel Metal Hydride batteries must be recycled or disposed of properly.

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

22.2 volts. LiPo batteries have a minimum safe discharge voltage threshold that

should not be exceeded. The Velineon VXL-6s Marine 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. 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.

TOOLS, SUPPLIES AND REQUIRED EQUIPMENT

Your model comes with a set of specialty metric tools. You’ll need to purchase other items, available from your hobby dealer, to operate
and maintain your model.

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 the 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, low-resistance 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.

TRAXXAS TQ 2.4GHz RADIO & VELINEON POWER SYSTEM

8 • SPARTAN

INTRODUCTION

Your model includes the latest Traxxas TQ 2.4GHz transmitter with
Traxxas Link™ technology. 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

24) and Menu Tree (page 26) included in this manual will help
you understand and operate the advanced functions of the new
TQ 2.4GHz radio system. For additional information and how-to
videos, visit Traxxas.com.

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 24.

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,
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.

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-6s Marine
electronic speed control uses advanced circuitry to provide
precise, digital proportional throttle control. Electronic speed
controls use power more efficiently than mechanical speed
controls so that the batteries run longer. An electronic speed
control also has circuitry that prevents loss of steering and
throttle control as the batteries lose their charge.

Frequency band - The radio frequency used by the transmitter to

send signals to your model. This model operates on the 2.4GHz
direct-sequence spread spectrum.

kV Rating - Brushless motors are often rated by their kV number.

The kV rating equals no-load motor rpm with 1 volt applied. The
kV increases as the number of wire turns in the motor decreases.
As the kV increases, the current draw through the electronics also
increases.

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.

Motor Over-Temperature Detection – The receiver monitors

the motor temperature and reduces power to 25% when it
detects a temperature that is above the normal operating range.
Disconnecting the battery and allowing the motor to cool will
reset the system to full power. See page 23 for more information.

Neutral position - The standing position that the servos seek when

the transmitter controls are at the neutral setting.

NiCad - Abbreviation for nickel-cadmium. The original rechargeable

hobby pack, NiCad batteries have very high current handling,
high capacity, and can last up to 1000 charging cycles. Good
charging procedures are required to reduce the possibility of
developing a “memory” effect and shortened run times.

NiMH - Abbreviation for nickel-metal hydride. Rechargeable

NiMH batteries offer high current handling, and much greater
resistance to the “memory” effect. NiMH batteries generally
allow higher capacity than NiCad batteries. They can last up to

TRAXXAS TQ 2.4GHz RADIO & VELINEON POWER SYSTEM

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-6s Marine electronic speed control is designed for use with
sensorless motors.

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-6s Marine 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.

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-6s Marine 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 TQ radio system, consisting of

the receiver, the transmitter, and the servos. The system uses
two channels: one to operate the throttle and one to operate
the steering.

Voltage - Voltage is a measure of the electrical potential difference

between two points, such as between the positive battery
terminal and ground. Using the analogy of the garden hose,
while current is the quantity of water flow in the hose, voltage
corresponds to the pressure that is forcing the water through the
hose.

IMPORTANT RADIO SYSTEM PRECAUTIONS

For maximum range, always hold the transmitter so the antenna

is in a vertical position (pointing straight up). The transmitter’s
antenna can be swiveled and angled to allow for a vertical
position if necessary.

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. Always keep
the wire protected (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.

indicate the charge level of the battery pack installed in the model.
Refer to the Transmitter LED Codes table on page 25 for more
information on the transmitter Status LED codes.

*

CHARGING THE BATTERY PACKS

The most convenient type of charger for charging the included
battery packs is an AC peak-detecting charger that plugs directly
into an AC wall outlet, such as the TRX EZ-Peak™ (Part #2930).
It contains special peak-detection circuitry that automatically
shuts the charger off when the battery is fully charged.

For faster charging, the included batteries may be charged at
4 amps. The TRX EZ-Peak is a 4 amp charger and will charge one
included battery in only 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.

The Traxxas High Current Connector

Your model is equipped with the patented
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.

Use the Right Batteries

Your transmitter uses
AA batteries. Use new
alkaline batteries, or
rechargeable batteries
such as 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 on the
transmitter) to avoid losing
control.

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
25 to identify the code.

*A Quick Reference Guide has been provided for you in the battery compartment of the transmitter. Always store the Quick Reference Guide in your transmitter.

batteries, simply loosen
the straps, slide the battery
pack beneath them, and
tighten the straps to
hold the batteries snugly
against the battery tray’s
foam pads. They should be
tight enough to prevent
the batteries from sliding,
but should not be pulled
excessively tight. If you
wish to use other positions in the battery tray, simply remove the
straps and reinstall them in the additional channels provided.
Assemble the straps as shown in the illustration.

Positioning the Battery Packs

• Battery Packs Forward: This is the standard battery position for

Spartan. Placing the battery packs at the front of the battery trays will
give Spartan the greatest stability in all water and wind conditions.
Whether you are using the included Power Cell 7-cell batteries or
aftermarket NiMH or LiPo packs, always begin with the batteries in
the forward position.

• Battery Packs Centered: Smooth water and calm winds may allow
you to move the battery packs rearward in the hull to allow the
bow to ride higher and increase Spartan’s speed. Be aware that
positioning the batteries farther aft increases the likelihood of the
boat blowing over at speed or becoming unstable.

• Battery Packs Aft: Positioning the batteries all the way back in their
trays may provide higher top speeds but will also make Spartan
more prone to blowing over, spinouts, and instability. Experiment
with this position only in very calm conditions, and closely monitor
the hull’s attitude as you increase speed.

TQ 2.4GHz RADIO SYSTEM CONTROLS

TQ RADIO SYSTEM RULES

Always turn your TQ

2.4GHz 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 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 batteries.

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.

TQ 2.4GHz 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 16 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 15.

To change the throttle neutral adjust

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

Automatic Fail-Safe

The TQ 2.4GHz transmitter
and receiver are equipped
with an automatic fail­safe system that does not
require user programming.
In the event of signal loss
or interference, the throttle
will return to neutral and
the steering will hold its
last commanded position. If
Fail-Safe 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.

TQ 2.4GHz RADIO AND VELINEON POWER SYSTEM

USING THE TQ 2.4GHZ RADIO SYSTEM

The TQ 2.4GHz 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 the included stand. Make sure your hands

are clear of the moving parts of the model. Keep fingers and

objects away from the propeller!

3.

Plug the battery packs in the model into the speed control. This
turns the speed control on.

4.

Turn the steering wheel on the transmitter back and forth and
check for rapid operation of the steering servo. Also, check that
the steering mechanism is not loose or binding. If the steering
operates slowly, check for weak batteries.

6.

When looking down at the rear of model,
the rudder should be pointing straight
back. If the rudder is turned slightly to
the left or right, slowly adjust the steering
trim control on the transmitter until it is
pointing straight back.

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 your adjustments have been made, turn the receiver and the

model off by unplugging the batteries, then switch off the receiver.
The receiver is always switched off last.

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 watch the model. Make sure hands and

clothing are clear of the propeller and other moving
parts on the model.

3.

Make sure your transmitter antenna is fully upright, and then

walk away from the model with the transmitter until you reach
the farthest distance you plan to operate the model.

4.

Operate the controls on the transmitter once again to be sure

that the model responds correctly.

5.

Do not attempt to operate the model if there is any problem

with the radio system or any external interference with your
radio signal at your location.

• Higher Speeds Require Greater Distance

The faster you drive your model, the more quickly it will near the
limit of radio range. At 50mph, a model can cover 73 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 midpoint of the model’s
running area, not the far end, so you drive back and forth 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.

TQ 2.4GHz 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.

2. Press and hold the receiver’s LINK button as you plug in the
speed control.

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.

TQ 2.4GHz RADIO AND VELINEON POWER SYSTEM

Steering Sensitivity (Exponential)

The Multi-Function knob on the TQ2.4GHz 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
center will result in “negative exponential” and decrease steering
sensitivity by making the servo less responsive near neutral, with
increasing sensitivity as the servo nears the limits of its travel range.
The farther you turn the knob, the more pronounced the change
in steering servo movement will be. The term “exponential” comes
from this effect; the servo’s travel changes exponentially relative
to the input from the steering wheel. The exponential effect is
indicated as a percentage—the greater the percentage, the greater
the effect. The illustrations below show how this works.

Normal Steering Sensitivity (0% exponential)

In this illustration,
the steering servo’s
travel (and with it,
the steering motion
of the model’s
rudder) corresponds
precisely with the
steering wheel. The
ranges are exaggerated
for illustrative purposes.

Decreased Steering Sensitivity
(Negative Exponential)

By turning the

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 your
model at high speeds, or anytime a less aggressive steering feel is
desired. The ranges are exaggerated for illustrative purposes.

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. The antenna is secured by a 3x4mm set screw. To remove
the antenna tube, simply remove the set screw with the included

1.5mm wrench.

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,
then install the set screw next to the antenna tube. Use the supplied

1.5mm wrench to tighten the screw just until the antenna tube
is securely in place. Do not over tighten.

The VXL-6s Marine speed control is factory set and should not require any
adjustments. These instructions are provided for your reference.

VXL-6s Battery Settings (Low-Voltage Detection Setting)

The Velineon VXL-6s Marine 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-6s
will limit the power output to 50% throttle so you may bring the boat back to
shore. When the battery voltage attempts to fall below the minimum threshold,
the VXL-6s will shut down all motor output. The LED on the speed control will
slowly blink red, indicating a low voltage shutdown. The VXL-6s will stay in the
reduced power mode until a fully charged battery is connected.

Your model includes two Power Cell NiMH batteries. The VXL-6s speed control’s
Low-Voltage Detection has been disabled for best performance with these
batteries. The speed control’s LED will glow red when it is turned on, indicating
Low-Voltage Detection is disabled. Be certain to activate Low- Voltage

Detection if you install LiPo batteries in your model. Never use LiPo batteries

while Low-Voltage Detection is disabled.

Verify Low-Voltage Detection setting:

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

2. Connect two fully charged batteries to the VXL-6s.

3. If the ESC’s LED glows red, then the Low-Voltage Detection is DISABLED
(not safe to use LiPo batteries). If the LED glows green, then Low-Voltage
Detection is ACTIVATED.

To activate Low-Voltage Detection (LiPo setting):

1. Turn on the transmitter and hold the trigger to full reverse.

2. While holding the trigger to full reverse, connect two fully
charged batteries to the VXL-6s.

3. Continue to hold reverse. After about ten seconds, the red
LED will go out and the green LED will switch on. You will
also hear a ‘rising’ musical tone.

To disable Low-Voltage Detection (NiMH setting):

1. Turn on the transmitter and hold the trigger to full reverse.

2. While holding the trigger to full reverse, connect two fully
charged batteries to the VXL-6s.

3. Continue to hold reverse. After about ten seconds, the green
LED will go out and the red LED will switch on. You will also
hear a ‘falling’ musical tone.

Transmitter Adjustments for the VXL-6s Marine speed control

Before attempting to program your VXL-6s Marine electronic speed control
(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 ESC. Follow the steps below if your transmitter is not
already adjusted as follows:

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 glow green and the transmitter is
restored to default.

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
batteries, wait a few seconds, plug the batteries back in, and start over.

1. Place the boat on the included stand. Always make sure that objects and
fingers are clear of the prop.

2. Turn on the transmitter. Pull and hold the trigger to full throttle.

3. While holding full throttle, connect two fully charged battery packs to the
VXL-6s Marine ESC. It will turn on automatically.

4. Continue to hold the transmitter trigger at full throttle. After about two
seconds, the ESC will beep once and its red LED will light. The full throttle
position is now stored.

5. Move the trigger up to the full reverse position and hold it there. After about
two seconds, you will hear two beeps and red LED will blink twice. The reverse
throttle position has been stored.

6. Release the trigger so it is at the neutral position. The ESC will beep three
times and the red LED will blink three times. After a short pause, the ESC will
beep three more times and the LED will blink three times (red, red, green). The
speed control is now programmed and ready for use.

VXL-6s Marine Operation

To operate the speed control and test the programming, place the boat on
the included stand so the propeller is off the ground. Always make sure that
objects and fingers are clear of the prop.

1. Turn the transmitter on.

2. Connect two fully charged batteries to the ESC. It will turn on automatically.
The ESC will beep three times and blink three times (red, red, green).

3. One LED will glow. If the red LED is glowing, it means Low-Voltage Detection
has been switched off for use with NiMH batteries (as included with the
Spartan). The green LED will glow when Low-Voltage Detection is enabled, for
use with LiPo batteries. Low-Voltage Detection must be switched on when
operating the model with LiPo batteries. See the Low-Voltage Detection
Setting section for more information.

4. Pull the transmitter’s trigger toward the grip to apply forward throttle. The LED
will go out, then glow at full throttle.

ADJUSTING THE ELECTRONIC SPEED CONTROL

5. Return the trigger to neutral and allow the prop to stop. Note that there is no
programmed delay when changing from reverse to forward. Use caution to
avoid slamming the speed control from reverse to forward and vice versa. This
could result in driveline damage.

6. Push the trigger away from the grip to apply reverse throttle. The LED will go
out, then glow at full throttle. (Note that reverse throttle is only about 15% of
forward throttle. This is normal.)

7. To turn the speed control off, unplug the batteries.

Thermal Shutdown Protection

The VXL-6s Marine is equipped with thermal shutdown protection to guard
against overheating caused by excessive current flow. If the operating
temperature exceeds safe limits, the VXL-6s Marine will automatically shut down
and the ESC’s red LED will blink. The LED will continuously blink red, even if the
throttle trigger is moved back and forth. After the ESC cools down to a safe level,
the ESC will once again function normally.

VXL-6s Marine Profile Selection

The speed control is factory set to Profile 1. To change the profile, follow the
steps on described below. The speed control should be connected to the
receiver and the transmitter should be adjusted as described previously. The
profiles are selected by entering the programming mode.

VXL-6s Marine Profile Description:

Over-Voltage Detection

The VXL-6s Marine speed control also detects when too much voltage is being
input. If batteries with more than 25.2 volts are connected to the speed control,
it will not operate. The red and green LEDs will blink, and an alternating high-low
tone will sound. Unplug the batteries and install packs with 25.2 volts or less.

Throttle Neutral Protection

If the transmitter’s throttle neutral position is moved after the VXL-6s speed
control has been switched off, the speed control will not recognize the new
position when it is turned back on and will not operate the throttle. This
prevents the boat from running out of control due to an accidental change
of the neutral position. If Throttle Neutral Protection detects that the throttle
neutral position has changed, the VXL-6s speed control’s green LED will blink
and it will beep steadily. Return the throttle trim position to neutral to resume
normal throttle operation.

DRIVING YOUR MODEL

Caution! If your model
suddenly stops running or
runs very slowly, release the
throttle immediately! Refer
to Troubleshooting on page
23 for more information.

18 • SPARTAN

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.

• Use extra caution when traveling into the wind and/or against the direction
of waves. The added pitch motion caused by driving into cresting waves
combined with wind blast tends to lift the boat out of the water further and
might cause the boat to blow over backwards.

• If the boat starts getting very light on the water (about to blow over) reduce
throttle to settle the hull back into the water.

• Always be ready to reduce the throttle if your model appears to be unstable
or “chine walking” (rocking violently from side to side). Make trim tab or
weight placement changes to reduce chine walking, as this behavior can
cause a crash in rougher water.

• Always reduce the throttle when turning, especially in rough water. Once the
boat has begun leaning into the corner increase throttle to maintain speed
and keep the bow up.

• Use caution when driving parallel to waves or wind chop. The waves will cause
excess rocking and may cause the boat to spin out or crash unexpectedly.

• When traveling at high speeds (40+ mph) be very gentle with control inputs
to avoid hooking or flipping the boat.

• Avoid reversing for more than a few seconds at a time. Reversing causes
water to rush over the stern of the boat and may cause it to sink.

• Drain the boat after every run. Even though every precaution has been made
to keep water out of the hull it may be necessary to drain any ingested water.
Excess water in the hull will hurt performance and unbalance the boat.

• Do not leave the boat sitting in the water after each run. Water could enter
the boat if the stuffing tube seal is worn.

• Do not operate the boat continuously at low speeds when using LiPo
batteries. The ESC and motor could overheat from lack of cooling water flow.

• Remove the prop for transportation to avoid accidentally breaking it.

• Do not lift the boat by grabbing the sides of the hatch opening. This may
cause the upper hull to tear. Instead use two hands to lift or handle the boat,
grabbing the sides of the hull about 1/3 way up from the back.

• To prevent spin outs, avoid steering sharply at high speed.

• Jumping your model or towing anything with it should not be attempted.

• Return your model to shore at the first sign of weak batteries. Your model
will begin to slow and the controls will become sluggish.

Cavitation

If your model is running at full throttle but is only barely moving forward
then the propeller is cavitating. Try advancing the throttle slowly to get
your model on plane. If you are having trouble with cavitation, check the
propellers for nicks or tangled debris. Your model’s propellers are specially
designed for their application and are very sensitive to any changes or

7

modifications. If a prop is damaged it should be replaced.

Where to Run

Select a body of fresh water, which is calm and free of debris, tree stumps,
moss, etc. Do not drive your model in extremely rough, choppy water or in
high wind (more than 15 MPH). These conditions could cause your model
to flip over. Also, find a clean, stable area of shoreline to launch from. The
water must be at least 10-inches deep. Be aware that some ponds restrict
the use of model boats. Always choose a launch site which is downwind
so that the wind and waves will drift the boat back to you if it should ever
become disabled or capsize. Running your model in salt water is not

recommended. Damage from corrosion is not covered by the warranty.
Your model is too fast to run in a swimming pool.

BOAT RETRIEVAL

If your model accidentally flips over and fills with water, it is equipped
with foam flotation to help prevent it from sinking. Traxxas does not
recommend swimming or wading to retrieve a boat. If you have chosen
your launch sight carefully (downwind), your model will probably drift
back to you on its own. If there is no wind, you will need a tennis ball and
a length of string. Tie the tennis ball securely to one end of the string
and then throw the ball over the drifting boat. Pull the ball in and try to
entangle the boat in the string. Pull the boat back slowly to shore. If only
the bow of the boat remains visible, try using a fishing lure with many
hooks and a fishing pole. Try to snag the lip of the upper deck or drive
mechanism with the hooks.

RUN TIME

Your model is able to achieve long run times due to the greater efficiency
of the high voltage electrical system. 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 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 for us to give you
exact run times for your model. Another major factor which affects run
time is how your model is driven. Our experience has shown that the run
times are shorter when the boat is driven continuously at top speed.

Tips for Increasing Run Time

• Use a high-quality peak-detecting charger.

• Discharge the batteries completely after each run.

• Vary your speed. Continuous high speed shortens the run time on your model.

• Maintain your model. Do not allow debris or damaged parts to cause
binding in the drivetrain. Keep the motor clean and the motor bearings
lightly lubricated.

• Apply the throttle smoothly. Hard acceleration, especially from a stop, will
shorten your run time.

ADJUSTING YOUR MODEL

Adjusting the Trim Tabs

Spartan features stainless-steel trim tabs to help set the angle
of the boat’s hull as it rides in the water. Setting the trim angle
correctly will provide maximum speed and efficiency from your
model. From the factory, the trim tabs are set for best all-around
performance and stability at Spartan’s maximum speed, but you
can experiment with their position to improve performance.
Slightly bending the tabs down will cause the bow to run closer
to the water, “wetting” more of the hull and increasing stability.
Be sure to set the left and right trim tabs equally.

Optional Accessory: Machined
Aluminum Trim Adjusters

For the most precise trim
adjustments, Spartan can
be outfitted with machined
aluminum trim adjusters.

A

Hold a straightedge against the hull so it
extends past the trim tab. The tab will rest
on the straightedge or be within 1mm of
its edge. This is the stock setting. Rigorous
testing has shown this setting to offer the
best handling in most conditions.

B C

To adjust the trim tab,
grip it securely with a pair of
pliers as close to the bend as
possible. Flex the trim tab down
to set a new angle. Note that the
trim tab has some spring-back,
and will need to be flexed slightly
farther than the actual position
you wish to set.

This illustration shows 1mm of
downward defection. This small setting
will cause a significant change in the
hull’s attitude. Settings of 2-3mm
deflection should be considered
the maximum.

These install using the
existing trim tab mounting
holes, so no drilling is
required. Once installed,
the adjusters’ stainless­steel screws can be used
to make fine trim settings.
Once Spartan is trimmed to
your preference, corrosion­resistant nickel-plated nuts
hold the adjustment. Refer
to the parts list for more
information and accessories.

ADJUSTING YOUR MODEL

Adjusting the Rudder Angle

Spartan features an adjustable rudder support that permits the angle

Rudder Angle
Adjustment Screws

of the rudder to be changed to alter the model’s cornering feel. The
stock setting is 0°, or ‘vertical,’ meaning the rudder is parallel with the
transom (see illustration). By loosening the rudder angle adjustment
screws, the rudder can be pivoted back up to 3°. Altering the rudder
angle effects how much the rudder ‘lifts’ the hull while cornering.
Increasing the rudder angle will allow the hull to ride higher while
cornering, which may potentially raise cornering speeds but also
lessens stability. If you experiment with this feature, remember to
retighten the adjustment screws after making your setting.

Stock Position 0°

(Parallel to back of boat)

Adjusting the Drive Strut

Spartan has a surface-piercing prop, meaning the prop is not fully submerged when the model is at speed. Varying
the depth that the prop is submerged will alter the model’s performance. The stock setting is 4mm above the
lowest point of the hull. To adjust prop depth, loosen the drive strut adjustment screw and angle the strut down.
The minimum setting is approximately 2mm above the bottom of the hull. Submerging more of the prop may
increase speed with lower-voltage battery configurations, but amp draw will also be increased (the electronic
speed control and batteries will have to ‘work harder,’ reducing battery life). For maximum performance with most
battery configurations and in most conditions, the stock setting is best.

MAINTAINING YOUR MODEL

Your model requires maintenance in order to stay in top running
condition. The following procedures should be taken very
seriously. Form the habit of visually inspecting the mechanical
integrity of the model before and after each run.

Inspect the model for obvious damage or wear:

• Normally, some water will accumulate inside the boat. Empty any
standing water out of the boat between runs. Pour any water out
the side or back of the boat.

• Check the wiring for any frayed wires or loose connections.

• Check the tightness of the set screws in the collars on the steering
linkages, in the propeller. Thread-locking compound can be
applied to these screws to prevent them from loosening.

• Check the mounting of the receiver and servo.

• Check the driveshaft seals for damage. Do not attempt to run the
model if these seals are damaged in any way.

• Check the tightness of the propeller. Visually inspect the prop for
nicks, dings, and warping. Replace if any damage is noticed.

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

• Visually inspect the hull for any cracks, damage, or possible leaks.

•

Drain all water out of the model and thoroughly dry it before you store
it. Store the model with the top deck removed so that any remaining
moisture will evaporate.

After each run:

• Make certain the motor is completely dry, particularly the bearings.

• Lubricate the motor bearings with the light oil included with
your model.

• Release the drive cable from the collet as explained on page 22
and remove the drive cable by pulling the propeller away from
the drive strut. Thoroughly dry the drive cable and lubricate it
with the light oil included with your model.

• While the drive cable is removed from the model, dry and
lubricate the bushings in the drive strut. Apply oil to the exposed
bushing faces, and also apply a few drops of oil to the oiling
hole in the drive strut. Reinstall the drive cable by reversing the
removal steps.

• Keep all of the screws in the drive system tight.

Storage:

• Disconnect and remove all batteries.

• Thoroughly clean and dry the model before storing it.

• Always store the model with the top deck cover removed. This
will allow harmful moisture and condensation to evaporate.

Centering your Servo

Whenever your radio system has been removed for service or
cleaning, the steering servo must be re-centered prior to installing
the radio system in the model.

1. If the radio system is already installed in the boat, disconnect

the servo horn from the servo.

2. Connect the steering servo to channel 1 on your receiver and

the electronic speed control to channel 2.

3. Place fresh “AA” batteries in the transmitter and turn the power

switch on.

4. Turn the throttle and steering trim adjustments to the

center position.

5. Keep fingers and objects away from the propeller. Connect two

fresh battery packs to the electronic speed control. The servo
will automatically jump to its center position.

6. The servo horn is now ready to be installed.

7. Be careful not to move the servo shaft when installing the

linkages. Readjust the electronic speed control as described in
the previous section.

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

space. To remove the power module, follow these steps:

1. Loosen the drive cable collet.
Using the two 10mm wrenches
supplied, grip the collet base and
collet clamp. Rotate the parts

6

away from each in the direction
shown to loosen the clamp. You
do not have to fully unthread the
collet, it will take less than one
full rotation to loosen the clamp.

2. Remove the drive cable. Pull the propeller away from the drive

strut. The cable will come out with the propeller. There is no need
to remove the prop from the cable.

3. Remove the steering linkage. Use the supplied 2.5mm wrench to
unthread the 15mm screw in the servo arm and disengage the
steering linkage.

4. Unplug the water cooling outlet tube (A) and inlet tube (B).

5. Loosen the retaining screws. Use the supplied 2.5mm wrench to loosen the screws approximately 5 full

turns. It is not necessary to remove these screws, only loosen them.

6. Gently lift the power module from the motor end. If it does not release easily from the hull rails, loosen the
retaining screws another turn.

7. Slide the power module forward. Gently pull on the module to slide the tabs out of the slots in the hull rails.

Note: Sometimes the stuffing tube sticks in the seal. Extra force may be required to break it free.

TROUBLESHOOTING

The following section addresses some very basic questions you may have about your
model. If you can’t find a solution here, you may call Traxxas Customer Service at
1-888-TRAXXAS (U.S. residents only).

If the model stopped suddenly:

• Release the transmitter trigger immediately. Do not try and “force” the model to move.
Refer to the Boat Retrieval section on page 18 for recovery.

If there is an inconsistent reduction in power:

• There could be something wound around the prop (such as trash, algae
or fishing line). If you continue to drive your model with a bound prop,
the high load could create excessive heat and seriously damage the batteries, speed
control, or motor. Refer to the Boat Retrieval section on page 18 for recovery.

• The model might have struck an object in the water causing driveline damage. Refer to
the Boat Retrieval section on page 18 for recovery.

If there is an immediate reduction in power:

If the model’s power output is reduced suddenly, it is likely because the Low-Voltage
Detection or Motor Over-Temperature Detection systems have switched on.

• Low-Voltage Detection will reduce power output to 50% if low battery voltage is
detected. Return the boat to shore immediately to recharge the batteries. The LED on the
speed control will slowly blink red, indicating a low voltage shutdown.

• Motor Over-Temperature Detection will reduce power to 25% if the motor’s temperature
exceeds its normal operating range. Drive the model back to shore, the LED on the
receiver will flash red, indicating motor over-temperature. Disconnect the battery, and
allow the motor to cool. While the motor cools, inspect the model for possible causes of
overheating. These may include:

• Worn motor bearings

• Driveline binding due to insufficient lubrication or wear

• Debris wrapped around the prop

• Plugged or disconnected water-cooling lines

Full power will be restored when the motor has cooled and a battery is reconnected to
the speed control. Allowing the motor to cool without disconnecting the battery will not
restore full power. Always disconnect the battery if Motor Over-Temperature Detection
reduces the model’s power.

• If you are not sure which of the above conditions occurred, do not operate the model.
Refer to the Boat Retrieval section on page 18 for recovery.

INCREASING PERFORMANCE

While your model is a great performer out of the box, there are
steps you can take to increase the speed of the boat.

1. Adjust the trim tab angle correctly. The trim tab angle should be trimmed down just
enough to keep the bow of the boat from porpoising (bouncing up and down) in the
current water conditions. If the trim tabs are set too low, then it pushes the bow lower
and increases drag in the water (see page 19).

2. Maintain your boat. Your model will be faster if it is kept clean and in good working
order. Replace the prop if it gets nicked or damaged. Keep the motor clean and oiled.
Make sure the drivetrain turns freely with no binding or excess friction.

3. Use the best batteries and charger you can afford. Low-cost, low-capacity battery
packs will limit the performance of your model. Likewise, a low-cost charger may not
allow your batteries to achieve their peak power and capacity. For best performance, use
battery packs rated for 3000mAh or higher. Traxxas Power Cell NiMH packs are specially
constructed for durability and performance in high-power Traxxas models. The Traxxas
EZ-Peak charger (#2930) is recommended for use with Power Cell NiMH batteries. If you
plan to purchase LiPo batteries, consult your local hobby dealer or call 1-888-TRAXXAS
for advice on purchasing the appropriate LiPo batteries and LiPo charger for your model.

Using Aftermarket Props
Spartan’s included prop has been carefully designed for maximum performance and
durability. It does not require sharpening or balancing and is inexpensive to replace if
damaged. If you do wish to experiment with aftermarket props, Traxxas recommends using
props that range in diameter from 38-42mm, with a pitch-to-diameter ratio of about 1.4:1
(To determine this ratio, divide pitch by diameter. For example, the Spartan’s stock prop is
42mm in diameter with a pitch of 59mm. 59 ÷ 42 = 1.404). Avoid props larger than 42mm,
as these will increase amp draw and reduce performance.

Using Aftermarket Motors and Speed Controls

Important: The Velineon VXL-6s Marine Speed Control and Velineon 540XL motor have

been optimized to work together for the absolute best performance, reliability, and
efficiency. Using an aftermarket motor with the VXL-6s speed control, or an aftermarket
speed control with the Velineon 540XL motor, may result in damage to the Traxxas
components and/or aftermarket components. Damage incurred by mixing Traxxas and
aftermarket components will not be covered by any expressed or implied warranty. Only
use the Velineon VXL-6s Marine speed control with the Velineon 540XL motor.

If you wish to outfit your model with an aftermarket brushless system, you must replace both
the motor and the speed control. Traxxas recommends a motor with a kV rating of 1600-1800
kV. Make certain the speed control you choose is compatible with your motor, is designed
for marine use, and is waterproof. Water cooling is highly recommended. Additional silicone
tubing may be required to properly plumb your speed control’s water-cooling system. The
Traxxas water-cooling motor jacket is not compatible with all motors. Install an appropriate
water-cooling system for the motor you choose. Traxxas is not responsible for damage to
your model or the components you install in the model if you replace the Velineon power
system with non-Traxxas components. Note: The Motor Temperature Sensor may not fit onto
aftermarket motors and will not work with an aftermarket receiver.

For the best performance, we highly recommend the Spartan’s factory-installed Velineon
brushless system. It is optimized for the best performance, reliability, and ease of use in the
Spartan and fully supported by Traxxas customer service.

TQ 2.4GHz ADVANCED TUNING GUIDE

Starting Over:

Restoring Factory Defaults

When programming your

2.4GHz 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.

24 • SPARTAN

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 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 26. 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 15, 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 Multi­Function 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 tightest turn, thus
making the vehicle easier to drive throughout the rest of the course.
Reducing steering throw can also be useful in making a car or truck
easier to control on high-traction surfaces, and limiting steering output
for oval racing where large amounts of steering travel are not required.

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 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.

Steering and Throttle End Points

The TQ 2.4GHz 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 vehicle) 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.

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.

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.

Braking Percentage

R/C boats do not have brakes, as the natural resistance of the water will
slow and stop the boat when the throttle is shut off. However, if you use
your TQ 2.4GHz transmitter with a car or truck, you may find the Braking
Percentage function useful. When set for Braking Percentage, the Multi­Function knob will control the amount of brake travel applied by the
throttle/brake 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).

TRAXXAS LINK

Traxxas Link is an exclusive, patent-pending feature of the TQ 2.4GHz
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.

TQ 2.4GHz ADVANCED TUNING GUIDE

Model Lock

The Traxxas Link feature can store up to twenty models (receivers) in its
memory. If you bind a twenty-first receiver, Traxxas Link 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 Traxxas Link 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, 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 MENU and SET 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.
