Important Points to Remember · Your model is not intended for use on public
roads or congested areas where its operation can conflict with or disrupt
pedestrian or vehicular traffic.
· Never, under any circumstances, operate the model in crowds of people. Your
model is very fast and could cause injury if allowed to collide with anyone.
· Because your model is controlled by radio, it is subject to radio
interference from many sources that are beyond your control. Since radio
interference can cause momentary losses of radio control, always allow a
safety margin in all directions around the model in order to prevent
collisions.
· The motor, battery, and speed control can become hot during use. Be careful
to avoid getting burned.
· Don’t operate your model at night, or anytime your line of sight to the
model may be obstructed or impaired in any way.
· Most importantly, use good common sense at all times.
Speed Control Your model’s electronic speed control (ESC) is an extremely
powerful electronic device capable of delivering high current. Please closely
follow these precautions to prevent damage to the speed control or other
components. · Disconnect the Battery: Always disconnect the battery or
batteries from the speed control when not in use.
· Insulate the Wires: Always insulate exposed wiring with heat shrink tubing
to prevent short circuits. · Transmitter on First: Switch on your transmitter
first before switching on the speed control to prevent runaways and erratic
performance. · Don’t Get Burned: The ESC and motor can become extremely hot
during use, so be careful not to touch them until they cool. Supply adequate
airflow for cooling. · Use the Factory-Installed Connectors: Do not change the
battery and motor connectors. Improper wiring can cause fire or damage to the
ESC. Please note that modified speed controls can be subject to a rewiring fee
when returned for service. · No Reverse Voltage: The ESC is not protected
against reverse polarity voltage. · No Schottky Diodes: External Schottky
diodes are not compatible with reversing speed controls. Using a Schottky
diode with your Traxxas speed control will damage the ESC and void the 30-day
warranty. · Always adhere to the minimum and maximum limitations of the speed
control as stated in the specifications table in the Owner’s Manual.

SAFETY PRECAUTIONS
WARNING! CAUTION! DANGER!
FIRE HAZARD! Your model is able to use LiPo batteries. Charging and
discharging batteries has the
potential for fire, explosion, serious injury, and property damage if not
performed per the instructions. Before use, read and follow all manufacturer’s
instructions, warnings, and precautions. In addition, Lithium Polymer (LiPo)
batteries pose a SEVERE risk of fire if not properly handled per the
instructions and require special care and handling procedures for long life
and safe operation. LiPo batteries are intended only for advanced users that
are educated on the risks associated with LiPo battery use. Traxxas does not
recommend that anyone under the age of 18 use or handle LiPo battery packs
without the supervision of a knowledgeable and responsible adult. Dispose of
used batteries according to the instructions.
Important Warnings for users of Lithium Polymer (LiPo) batteries: · Your model
is able to use LiPo batteries. LiPo batteries have a minimum safe discharge
voltage threshold that should not be exceeded. The electronic speed control is
equipped with built-in Low-Voltage Detection that alerts the driver when LiPo
batteries have reached their minimum voltage (discharge) threshold. It is the
driver’s responsibility to stop immediately to prevent the battery pack from
being discharged below its safe minimum threshold.
· Low-Voltage Detection is just one part of a comprehensive plan for safe LiPo
battery use. It is critical to follow all instructions for safe and proper
charging, use, and storage of LiPo batteries. Make sure you understand how to
use your LiPo batteries. If you have questions about LiPo battery usage,
please consult with your local hobby dealer or contact the battery

their useful life. · ONLY use a Traxxas iD charger to charge Traxxas iD
batteries. ONLY use a Lithium Polymer (LiPo) balance charger with a balance
adapter port to charge LiPo batteries. Never use NiMH or NiCad-type chargers
or charge modes to charge LiPo batteries. DO NOT charge LiPo batteries with a
NiMH-only charger. The use of a NiMH or NiCad charger or charge mode will
damage LiPo batteries and may cause fire, personal injury, and/or property
damage.
· NEVER charge LiPo battery packs in series or parallel. Charging packs in
series or parallel may result in improper charger cell recognition and an
improper charging rate that may lead to overcharging, cell imbalance, cell
damage, and fire.
· ALWAYS inspect your LiPo batteries carefully before charging. Look for any
loose leads or connectors, damaged wire insulation, damaged cell packaging,
impact damage, fluid leaks, swelling (a sign of internal damage), cell
deformity, missing labels, or any other damage or irregularity. If any of
these conditions are observed, do not charge or use the battery pack. Follow
the disposal instructions included with your battery to properly and safely
dispose of the battery.
· DO NOT store or charge LiPo batteries with or around other batteries or
battery packs of any type, including other LiPos.
· Store and transport your battery pack(s) in a cool dry place. DO NOT store
in direct sunlight. DO NOT allow the storage temperature to exceed 140°F or
60°C, such as in the trunk of a car, or the cells may be damaged and create a
fire risk.
· DO NOT disassemble LiPo batteries or cells.
· DO NOT attempt to build your own LiPo battery pack from loose cells.
Charging and handling precautions for all battery types:
· BEFORE you charge, ALWAYS confirm that the charger settings exactly match
the type (chemistry), specification, and configuration of the battery to be
charged. DO NOT exceed the maximum manufacturer recommended charge rate.
· DO NOT attempt to charge non-rechargeable batteries (explosion hazard),
batteries that have an internal charge circuit or a protection circuit,
batteries that have been altered from original manufacturer configuration, or
batteries that have missing or unreadable labels, preventing you from properly
identifying the battery type and specifications.
· ALWAYS use a Traxxas iD charger to charge Traxxas iD batteries. DO NOT use a
non-Traxxas charger to charge Traxxas iD batteries. It is not recommended, but
if you choose to use a non-Traxxas charger or battery, read and follow all of
the manufacturer’s warnings and instructions.
· DO NOT let any exposed battery contacts or wires touch each other. This will
cause the battery to short circuit and create the risk of fire.

TRAXXAS TQ 2.4GHz RADIO SYSTEM
INTRODUCTION
Your model includes the TQ 2.4GHz transmitter. When powered on, the TQ 2.4GHz
will automatically locate and lock onto an available frequency, allowing
multiple models to be raced together without frequency conflicts. Just switch
on and drive! The included TQ 2.4GHz radio system has been programmed for your
model at the factory and does not require adjustment, but it does have
settings you may need to access to maintain proper operation of your model.
The detailed instructions (page 16) included in this manual will help you
understand and operate the functions of the new TQ 2.4GHz radio system. For
additional information and howto 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.
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 synch with each other. The BL-2s electronic speed
control is optimized to virtually eliminate cogging.
Current – Current is a measure of power flow through the electronics, usually
measured in amps. If you think of a wire as a garden hose, current is a
measure of how much water is flowing through the hose.
ESC (Electronic Speed Control) – An electronic speed control is the electronic
motor control inside the model. The BL-2s electronic speed control uses
advanced circuitry to provide precise, digital proportional throttle control.
Electronic speed controls use
power more efficiently than mechanical speed controls so that the batteries
run longer. An electronic speed control also has circuitry that prevents loss
of steering and throttle control as the batteries lose their charge.
Frequency band – The radio frequency used by the transmitter to send signals
to your model. This model operates on the 2.4GHz direct-sequence spread
spectrum.
kV Rating – Brushless motors are often rated by their kV number. The kV rating
equals no-load motor rpm with 1 volt applied. The kV increases as the number
of wire turns in the motor decreases. As the kV increases, the current draw
through the electronics also increases. The BL-2s 3300 motor is a 3300 kV
motor optimized for the best speed and efficiency in lightweight 1/10 scale
models.
LiPo – Abbreviation for Lithium Polymer. Rechargeable LiPo battery packs are
known for their special chemistry, which allows extremely high energy density
and current handling in a compact size. These are high performance batteries
that require special care and handling. LiPo battery packs are for advanced
users only.
mAh Abbreviation for milliamp hour, a measure of the capacity of the battery
pack. The higher the number, the longer the battery will last between
recharges.
Neutral position – The standing position that the servos seek when the
transmitter controls are at the neutral setting.
NiCad – Abbreviation for nickel-cadmium. The original rechargeable hobby pack,
NiCad batteries have very high current handling, high capacity, and can last
up to 1000 charging cycles. Good charging procedures are required to reduce
the possibility of developing a “memory” effect and shortened run times.
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.
TRAXXAS TQ 2.4GHz RADIO SYSTEM
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.
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 BL-2s electronic
speed control is optimized for smooth sensorless control.
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 to 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.
2.4GHz Spread Spectrum This model is equipped with the latest RC 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.”
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 antenna wire. Kinks in the antenna wire will reduce
range.
· DO NOT CUT any part of the receiver 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.
· 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.

Using a Different Battery Configuration The battery hold-down can be flipped
to accommodate different height battery packs. Note: For taller batteries, an
extended battery hold-down, part #5827X, is available (sold separately). For
shorter batteries (6-cell), use the included foam block in the front of the
battery compartment.
The Traxxas iD® High-Current Connector Your model is equipped with the Traxxas
iD® High-Current Connector. Standard connectors restrict current flow and are
not capable of delivering the power needed to maximize the output of the
electronic speed control. The Traxxas connector’s goldplated 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.
SETTING UP THE ANTENNA
The receiver antenna and antenna tube must be properly installed before
operating your model. Follow these steps to install the antenna and antenna
tube:
1. Slide the antenna wire into the antenna tube to its full extent. When
fully inserted, the wire should reach to approximately 1/2 inch below the tube
cap. Do not leave any slack in the antenna wire.
2. Insert the base of the antenna tube into the antenna post. Take care not
to crimp the antenna wire.
3. Slide the crimp nut over the antenna tube and screw it onto the antenna
post.
4. Use the supplied tool to tighten the crimp nut on the post just until the
antenna tube is securely in place. Do not overtighten or crush the antenna

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 turn your transmitter on first.
Plug in the battery.
Turn on the model.
· 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.
· In order for the transmitter and receiver to bind to one another, the
receiver in the model must be turned on within 20 seconds of turning on the
transmitter. The transmitter LED will flash fast red, indicating a failure to
link. If you miss it, simply turn off the transmitter and start over.
· Always turn on the transmitter before plugging in the battery.
RADIO SYSTEM BASIC ADJUSTMENTS
Steering Trim The steering trim knob located on the face of the transmitter
adjusts the neutral (center) point of the steering channel. If your model
pulls to the right or left when the steering wheel is centered, turn the knob
until the model drives straight when the steering wheel is centered.
Channel Reversing The TQ 2.4GHz transmitter has been programmed with the
correct servo direction settings for your model and should not require
adjustment. These instructions are for reference and troubleshooting only.
Reversing a channel reverses the direction of the corresponding servo. For
example, if you turn the steering wheel to the right and the model turns left,
Channel 1 would need to be reversed to correct the servo direction. Use the
following procedures to reverse the steering and throttle channels, if
necessary. Servo reversing should only be required if you accidentally reset
the direction of a channel. Do not reverse the steering or throttle channels
unless necessary.
Steering reversing procedure: 1. Press and hold the SET button on the
transmitter for two
seconds. The status LED will flash green.
2. Turn and hold the steering wheel to the full left or full right position
(it does not matter which position you choose).
3. While holding the steering wheel in position, press the SET button to
reverse the channel.
4. The channel is now reversed. Confirm correct servo operation before
running your model.
TRAXXAS TQ 2.4GHz RADIO SYSTEM
Throttle reversing procedure: Note: Throttle reversing is often times
unnecessary on electric models, as issues with the throttle can usually be
solved by reprogramming the speed control and/or verifying that the motor is
wired correctly. Before attempting to reverse the throttle channel using the
procedure below, you should first recalibrate the speed control. Refer to “BL-
2s Setup Programming” on page 19.
1. Press and hold the SET button on the transmitter for two seconds. The
status LED will flash green.
2. Move and hold the throttle trigger to the full forward or full brake
position (it does not matter which position you choose).
3. While holding the throttle trigger in position, press the SET button to
reverse the channel.
4. The channel is now reversed. Recalibrate the speed control and then
confirm correct servo operation before running your model.
USING THE RADIO SYSTEM
The TQ 2.4GHz 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).
2. Elevate the model so that the rear tires are off the ground. If you are
holding the model, grip it firmly. 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. Press and release the EZ-Set button on the speed control to turn the model
on. The speed control’s LED will glow red. To turn the speed control off,
press the EZ-Set button until the LED turns off.
Note: If the LED shines green after the speed control is turned on, Low-
Voltage Detection is activated. This may cause poor performance from NiMH
battery packs. Make sure to turn the Low-Voltage Detection on when using LiPo
batteries. Never use LiPo batteries while Low-Voltage Detection is turned off.
See page 19 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

7. Operate the throttle trigger to ensure that you have full forward
and reverse operation, and that the motor stops when the
throttle trigger is at neutral.
8. Once adjustments are made, turn off your model, followed by the hand-held transmitter.
Range-Testing the Radio System Before each running session with you°r model,
you should range-te° st 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.
The TQ 2.4GHz transmitter has a directional antenna. For maximum range, hold the transmitter upright and pointed in the direction of the model. Pointing the transmitter away from the model will reduce radio range.
Using Reverse: While driving, push the throttle trigger forward to apply
brakes. Once stopped, return the throttle trigger to neutral. Push the
throttle trigger forward again to engage pro°portional reverse.

Failsafe Your Traxxas radio system is equipped with a built-in Failsafe
function that returns the throttle to its last saved neutral position in the
event of a signal loss. The LED on the transmitter and the receiver will
rapidly flash red when the Failsafe 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.

TRAXXAS TQ 2.4GHz RADIO SYSTEM
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 25 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.
Your model’s radio system is designed to operate reliably up to the
approximate distance that it is no longer easy or comfortable to see and
control the model. Most drivers will struggle to see and drive their model at
distances farther than a football field (300+ feet). At greater distances, you
could lose sight of your model and you may also exceed the radio system’s
operating range which will cause the Failsafe system to activate. For best
visibility and control of your model keep your model within 200 feet,
regardless of the maximum range available.
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.
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 SET button on the transmitter.
2. Turn on the transmitter and release the SET button. The status LED will
flash red slowly, indicating that the transmitter is in bind mode.
3. Press and hold the LINK button on the receiver.
4. Turn on the speed control by pressing the EZ-Set button and release the
LINK button.
5. When the LEDs on both the transmitter and the receiver turn solid green,
the system is bound and ready for use. Confirm that the steering and throttle
operate properly before driving your model.

ADJUSTING THE ELECTRONIC SPEED CONTROL
BL-2sTM Battery Settings (Low-Voltage Detection Setting) The BL-2s 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 BL-2s will limit the power output to 50% throttle.
When the battery voltage attempts to fall below the minimum threshold, the BL-
2s will shut down all motor output. The LED on the speed control will slowly
blink red, indicating a low-voltage shutdown. The BL-2s will stay in this mode
until a fully charged battery is connected.
When you turn your model on, the BL-2s speed control’s status LED will glow
green, indicating that Low-Voltage Detection is activated to prevent over-
discharging of LiPo batteries. LiPo batteries are intended only for the most
advanced users that are educated on the risks associated with LiPo battery
use.
WARNING: FIRE HAZARD! Do not use LiPo batteries in this vehicle with Low-
Voltage Detection disabled.
To verify the Low-Voltage Detection setting: 1. Turn on the transmitter (with
the throttle at neutral). 2. Connect a fully charged battery pack to the BL-
2s. 3. Press and release the EZ-Set button to turn the BL-2s on. If the LED is
solid red,
then the Low-Voltage Detection is DISABLED (not safe to use LiPo batteries).
If the LED is solid green, then Low-Voltage Detection is ACTIVATED.
To activate Low-Voltage Detection (LiPo setting): 1. Make sure the LED on the
BL-2s 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
BL-2s is on and green. 2. Press and hold the EZ-Set button for ten seconds.
The
LED will turn off and then light red. Also, a “falling” musical tone will be
emitted from the motor. 3. Low-Voltage Detection is now DISABLED.
Transmitter Adjustments for the BL-2s ESC Before attempting to program your
BL-2s ESC, it is important to make sure that your transmitter is properly
adjusted (set back to the factory defaults). Otherwise, you may not get the
best performance from your speed control.
The transmitter should be adjusted as follows: If the transmitter settings
have been adjusted, reset them to the factory defaults. 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.

DRIVING YOUR MODEL
Now it’s time to have some fun! This section contains instructions on driving
and making adjustments to your model. Before you go on, here are some
important precautions to keep in mind.
· Allow the model to cool for a few minutes between runs. This is particularly
important when using high-capacity (2400mAh and above) battery packs that
allow extended periods of running. Monitoring temperatures will extend the
lives of the batteries and motor.
· Do not continue to operate the model with low batteries or you could lose
control of it. Indications of low battery power include slow operation and
sluggish servos (slow to return to center). Stop immediately at the first sign
of weak batteries. When the batteries in the transmitter become weak, the red
power light will begin to flash. Stop immediately and install new batteries.
· Do not drive the model at night, on public streets, or in large crowds of
people.
· If the model becomes stuck against an object, do not continue to run the
motor. Remove the obstruction before continuing. Do not push or pull objects
with the model.
· Because the model is controlled by radio, it is subject to radio
interference from many sources beyond your control. Since radio interference
can cause momentary losses of control, allow a safety margin of space in all
directions around the model in order to prevent collisions.
· Use good, common sense whenever you are driving your model. Intentionally
driving in an abusive and rough manner will only result in poor performance
and broken parts. Take care of your model so that you can enjoy it for a long
time to come.
· High-performance vehicles produce small vibrations that may loosen hardware
over time. Frequently check wheel nuts and other screws on your vehicle to
ensure that all hardware remains properly tightened..
About Run Time A large factor affecting run time is the type and condition of
your batteries. The milliamp hour (mAh) rating of the batteries determines how
large their “fuel tank” is. A 3000 mAh battery pack will theoretically run
twice as long as a 1500 mAh sport pack. Because of the wide variation in the
types of batteries that are available and the methods with which they can be
charged, it’s impossible to give exact run times for the model.
Another major factor that affects run time is how the model is driven. Run
times may decrease when the model is driven repetitively from a stop to
topspeed and with repetitive hard acceleration.
Tips for Increasing Run Time · Use batteries with the highest mAh rating you
can purchase. · Use a high-quality peak-detecting charger. · Read and follow
all maintenance and care instructions provided by the
manufacturer of your batteries and charger. · Keep the BL-2s cool. Get plenty
of airflow across the ESC heat sinks. · Use the correct Low-Voltage Detection
setting for your battery (see page
19). Low-Voltage Detection can be off for maximum NiMH battery runtime. Never
use LiPo batteries while Low-Voltage Detection is turned off. · Lower your
gear ratio. Installing a smaller pinion or larger spur gear will lower your
gear ratio, causing less power draw from the motor and battery, and reducing
overall 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.
RUNNING IN WET CONDITIONS
Your new Traxxas model is designed with water-resistant features to protect
the electronics in the model (receiver, servos, electronic speed control).
This gives you the freedom to have fun driving your model through puddles, wet
grass, snow, and through other wet conditions. Though highly water resistant,
the model should not be treated as though it is submersible or totally, 100%
waterproof. Water resistance applies only to the installed electronic
components. Running in wet conditions requires additional care and maintenance
for the mechanical and electrical components to prevent corrosion of metal
parts and maintain their proper function.
Precautions · Without proper care, some parts of your model can be seriously
damaged
due to contact with water. Know that additional maintenance procedures will be
required after running in wet conditions in order to maintain the performance
of your model. Do not run your model in wet conditions if you are not willing
to accept the additional care and maintenance responsibilities.
· Not all batteries can be used in wet environments. Consult your battery
manufacturer to see if their batteries can be used in wet conditions.
· The Traxxas TQ 2.4GHz transmitter is not water resistant. Do not subject it
to wet conditions such as rain.

DRIVING YOUR MODEL
· Do not operate your model during a rain storm or other inclement weather
where lightning may be present.
· Do NOT allow your model to come in contact with salt water (ocean water),
brackish water (between fresh water and ocean water), or other contaminated
water. Salt water is highly conductive and highly corrosive. Use caution if
you plan to run your model on or near a beach.
· Even casual water contact can reduce the life of your motor. Special care
must be taken to modify your gearing and/or your driving style in wet
conditions to extend the life of the motor (details follow).
Before Running Your Vehicle in Wet Conditions 1. Consult the section “After
Running Your Vehicle in Wet Conditions”
before proceeding. Make sure you understand the additional maintenance
required with wet running.
2. The wheels have small holes molded in to allow air to enter and exit the
tire during normal running. Water will enter these holes and get trapped
inside the tires if holes are not cut in the tires. Cut two small holes (3mm
or 1/8″ diameter) in each tire. Each hole should be near the tire centerline,
180° 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 visibly
protruding from the edge of the cover.
4. Confirm that your batteries can be used in wet conditions.
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.
· Do not gear the motor by temperature when running in wet conditions. The
motor will be cooled by water contact and will not give an accurate indication
of appropriate gearing.
After Running Your Vehicle in Wet Conditions 1. Drain the tires by spinning
the tires at high speed to “sling” the
water out. One way to do this is to make several high-speed passes on a flat,
dry surface, if possible.
2. Remove the batteries.
3. Rinse excess dirt and mud off the truck with low-pressure water, such as
from a garden hose. Do NOT use pressure washer or other high-pressure water.
Avoid directing water into the bearings, transmission, etc.
4. Blow off the truck with compressed air (optional, but recommended). Wear
safety glasses when using compressed air.
5. Remove the wheels from the truck.
6. Spray all the bearings, drivetrain, and fasteners with WD-40® or similar
water displacing light oil.
7. Let the truck stand or you may blow off with compressed air. Placing the
truck in a warm, sunny spot will aid drying. Trapped water and oil will
continue to drip from the truck for a few hours. Place it on a towel or piece
of cardboard to protect the surface underneath.
8. As a precautionary step, remove the sealed receiver box cover. While
unlikely, humidity or tiny amounts of moisture or condensation may enter the
receiver box during wet running. This can cause long-term problems with the
sensitive electronics in the receiver. Removing the receiver box cover during
storage allows the air inside to dry. This step can improve the long-term
reliability of the receiver. It is not necessary to remove the receiver or
unplug any of the wires.
9. Additional Maintenance: Increase your frequency of disassembly,
inspection, and lubrication of the following items. This is necessary after
extended wet use or if the vehicle will not be used for an extended period of
time (such as a week or longer). This additional maintenance is needed to
prevent any trapped moisture from corroding internal steel components.
· Stub axle housing bearings: Remove, clean, and re-oil the bearings.
· Spur and pinion gears: Inspect the gears for wear, broken teeth, or any
debris lodged between the teeth. You do not need to lubricate the gears.
· Motor: Remove the motor, clean with aerosol motor cleaner, and re-oil the
bearings with lightweight motor oil. Be sure to wear eye protection when using
spray aerosol cleaners.
RECEIVER BOX: MAINTAINING A WATERTIGHT SEAL
Removing and Installing Radio Gear The unique design of the receiver box
allows the removal and installation of the receiver without losing the ability
to maintain a watertight seal in the box. The patent-pending wire clamp
feature gives you the ability to also install aftermarket radio systems and
maintain the watertight features of the receiver box.
Removing the Receiver 1. To remove the cover, remove the two 3x8mm button-head
cap
screws. 2. To remove the receiver from the box, simply lift it out and set to
the
side. The antenna wire is still inside the clamp area and cannot be removed
yet. 3. Remove the wire clamp by removing the two 2.5x8mm cap screws. 4.
Unplug the servo cables from the receiver and remove the receiver.
Receiver Installation 1. Always install the wires into the receiver
A
box before installing the receiver.
2. Install the antenna wire and the servo
cables into the receiver box.
3. Arrange the wires neatly using the wire
guides in the receiver box (A). The excess
B
wire will be bundled inside the receiver box. Label
which wire is for which channel.
4. Apply a small bead of silicone grease (Traxxas
part #1647) to the wire clamp (B).
C
5. Install the wire clamp and tighten the two
2.5x8mm cap screws securely.
6. Install the receiver into the box and plug the
wires into the receiver (C). Refer to page 12
for the wiring diagram.
7. Make sure the box light pipe is aligned with the receiver LED. Make
sure the O-ring is properly seated into the groove in the receiver box
so that the cover will not pinch it or damage it in any way.
8. Install the cover and tighten the two 3x8mm
button-head cap screws securely.
9. Inspect the cover to make sure that the O-ring seal is not visible.
DRIVING YOUR MODEL SLASH BRUSHLESS · 23
All of the toe links are installed on the truck so the left-hand thread
indicators point to the same direction. This makes it easier to remember which
way to turn the wrench to increase or decrease toe link length (the direction
is the same at all four corners). Note that the groove in the hex indicates
the side of the toe link with the left-hand threads.
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 counter-
clockwise one full turn.
ADJUSTING YOUR MODEL
Once you become familiar with driving your model, you might need to make adjustments for better driving performance
Adjusting the Slipper Clutch
The model is equipped with an adjustable
slipper clutch, which is built into the large
spur gear. The purpose of the slipper
clutch is to regulate the amount of power sent to the rear wheels to

the slipper clutch makes a high-
pitch, whining noise. Remove the rubber slipper clutch plug on the
Loosen
transmission cover in order to adjust the slipper. Use the 4-way wrench
to turn the adjusting nut clockwise to tighten and counterclockwise to
loosen. Place the model on a high-traction surface, such as carpet. Adjust
the slipper so that you can hear it slip for approximately two feet from a
standing, full throttle start. (Learn more about adjusting the slipper clutch
in the sidebar.)
Motor and Gearing One of the more significant advantages to your model’s transmission is the extremely wide range of available gear ratios. It can be geared low enough to run an extremely hot, modified motor. A modified motor should be geared lower (higher numerically) than a stock motor because it will reach its maximum power at higher rpms. A modified motor that is geared incorrectly can actually be slower than a correctly-geared, stock motor. Use the following formula to calculate the overall ratio for combinations not listed on the gear chart:
Spur Gear Teeth x 2.72 = Final Gear Ratio # Pinion Gear Teeth
The model is equipped with a BL-2s 3300kV motor. The gear combination that comes stock on each model provides good overall acceleration and top speed. If you want more top speed and less acceleration, install high-speed gearing (more teeth) or if you want more acceleration and less top speed, use a smaller pinion gear (optional gearing not included).
The BL-2s 3300kV is equipped with an integrated cooling fan that is effective during medium to high-speed operation. The gearbox is specially vented to cool the motor. Repetitive starting and stopping over short distances creates excess heat and will not allow the fan to cool the motor properly. For this type of driving, smaller pinion gears are recommended to reduce load on the motor.
Gearing Compatibility Chart (see sidebar) The chart in the sidebar shows a full range of gear combinations. This does NOT imply that these gear combinations should be used. Overgearing (bigger pinions, smaller spurs) can overheat and damage the motor and/or speed control.
Adjusting Gear Mesh
Incorrect gear mesh is the most common cause of
stripped spur gears. Gear mesh should be checked and
adjusted anytime a gear is replaced. To set
the gear mesh, cut a narrow strip of notebook Strip of
paper and run it into the gear mesh. Loosen
Paper
the motor screws and slide the motor and
pinion gear into the spur gear. Retighten the
motor screws and then remove the strip of
paper. You should be able to run a fresh strip
of paper through the gears without binding
them.
Motor Screws
If you are worried that you might be over-geared, check the temperature of the battery pack and motor. If the battery is extremely hot, and/or the motor is too hot to touch, your model is probably over-geared. If you are not able to run your model for at least four minutes before the battery dies, then change to a lower gear ratio. This temperature test assumes that the model is close to factory stock weight and operates freely with no excessive friction, dragging, or binding, and the battery is fully charged and in good condition.

any changes to the pistons, springs, or oil, always make
2. Connect the steering servo to channel 1 on the receiver. Connect the
changes to them in pairs (front or rear). Piston selection
depends on the range of oil viscosities that you have
available. For example, using a two-hole piston with
a lightweight oil will, at one point, give you the same
damping as a three-hole piston with heavier oil. We
recommend using the two-hole pistons with a range of oil viscosities from 10W to 50W (available from your

hobby shop). The thinner viscosity oils (30W or less) flow
more smoothly and are more consistent, while thicker
oils provide more damping. From the factory, the shocks
are filled with SAE-30W silicone oil. Use only 100% pure
silicone shock oil to prolong seal life. The model’s ride

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. The steering servo saver will wear out over time. If the
steering
becomes loose, the servo saver should be replaced. 10. Inspect the gears for
wear, broken teeth, or debris lodged
between the teeth. 11. Check the tightness of the slipper clutch.
Other periodic maintenance: · Slipper clutch pads
(friction material): Under normal use, the friction material in the slipper
clutch should wear very slowly. If the thickness of any one of the slipper
clutch pads is 1.8mm or less, the friction disc should be replaced. Measure
the pad thickness using calipers or measuring against the diameter of the 1.5
and 2.0mm hex wrenches provided with the model.
· Chassis: Keep the chassis clean of accumulated dirt and grime. Periodically
inspect the chassis for damage.
· Steering: Over time, you may notice increased looseness in the steering
system. There are several components that will wear out from use: the servo
saver (Traxxas part #3744), the bellcrank
bushings (Traxxas part #2545), and the tie rod ends (Traxxas part #2742).
Replace these components as needed to restore factory tolerances.
· Motor: Every 10-15 runs, remove, clean, and lubricate the motor. Use a
product such as electric motor cleaning spray to flush dirt out of the motor.
After cleaning, lubricate the bushings at each end of the motor with a drop of
light-weight electric motor oil.
· Shocks: Keep the oil level in the shocks full. Use only 100% pure silicone
shock oil to prolong the life of the seals. If you are experiencing leakage
around the top of the shock, inspect the bladder in the top cap for signs of
damage or distortion from overtightening. If the bottom of the shock is
leaking, then it is time for a rebuild. The Traxxas rebuild kit for two shocks
is part #2362.
· Suspension: Periodically inspect the model for signs of damage such as bent
or dirty suspension pins, bent turnbuckles, loose screws, and any signs of
stress or bending. Replace components as needed.
· Driveline: Inspect the driveline for signs of wear such as worn drive yokes,
dirty axle half shafts, and any unusual noise or binding. If a U-joint pops
apart, then it is time to replace the part. Remove the gear cover and inspect
the spur gear for wear. Check the tightness of the 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.
