ESC as stated in the specifications
table. Do not mix battery types
and capacities. Use the same
voltage and capacity for both
batteries. Using mismatched
battery packs could damage the
batteries and electronic speed
control.
• Insulate the Wires: Always insulate exposed or damaged wiring with heat
shrink tubing to prevent short circuits
• 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 speed control 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 the ESC will damage
the ESC and void the 30-day warranty.
LiPo Batteries
Lithium Polymer (LiPo) batteries are becoming popular for use in R/C models
due to their compact size, high energy density, and high-current output;
however, these types of batteries require special care and handling procedures
for long life and safe operation. WARNING: LiPo batteries are intended only for
advanced users that are educated on the risks associated with LiPo battery
use. Traxxas does not recommend that anyone under the age of 14 use or
handle LiPo battery packs without the supervision of a knowledgeable and
responsible adult.
Your model is able to use LiPo batteries with nominal voltage not to exceed 11.1
volts (3S packs). LiPo batteries have a minimum safe discharge voltage threshold
that should not be exceeded. The MXL-6s 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.

Applying the Decals
The main decals for your
model have been applied at
the factory. The decals are
printed on self-adhesive clear
mylar and are die-cut for easy
removal. Use a hobby knife to
lift the corner of a decal and
lift it from the backing.
To apply the decals, place
one end down, hold the
other end up, and gradually
smooth the decal down with
your finger as you go. This
will prevent air bubbles.
Placing both ends of the
decal down and then trying
to smooth it out will result
in air pockets. Look at the
photos on the box for typical
decal placement.

INTRODUCTION
Your model includes the latest Traxxas TQi 2.4GHz transmitter with
Traxxas Link™ Model Memory. The transmitter’s easy-to-use design
provides instant driving fun for new R/C enthusiasts, and also offers
a full compliment of pro-level tuning features for advanced users
– or anyone interested in experimenting with the performance of
their model. The steering and throttle channels feature adjustable
Exponential, End Points, and Sub-Trims. Steering and braking Dual
Rate are also available. Many of the next-level features are controlled
by the Multi-Function knob, which can be programmed to control
a variety functions. The detailed instructions (page 31) and Menu
Tree (page 34) included in this manual will help you understand and
operate the advanced functions of the new TQi radio system. For
additional information and how-to videos, visit Traxxas.com.
RADIO AND POWER SYSTEM TERMINOLOGY
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 31.
2.4GHz Spread Spectrum – This model is equipped with the latest
R/C technology. Unlike AM and FM systems that require frequency
crystals and are prone to frequency conflicts, the TQi system
automatically selects and locks onto an open frequency, and offers
superior resistance to interference and “glitching.”
BEC (Battery Eliminator Circuit) - The BEC can either be in the
receiver or in the ESC. This circuit allows the receiver and servos
to be powered by the main battery pack in an electric model.
This eliminates the need to carry a separate pack of 4 AA
batteries to power the radio equipment.
Brushless Motor - A D/C brushless motor replaces the brushed
motor’s traditional commutator and brush arrangement with
intelligent electronics that energize the electromagnetic
windings in sequence to provide rotation. Opposite of a brushed
motor, the brushless motor has its windings (coils) on the
perimeter of the motor can and the magnets are mounted to the
spinning rotor shaft.
Cogging - Cogging is a condition sometimes associated with
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.
Current - Current is a measure of power flow through the
electronics, usually measured in amps. If you look at wire like a
garden hose, current is a measure of how much water is flowing
through the hose.
ESC (Electronic Speed Control) - An electronic speed control is
the electronic motor control inside the model. Electronic speed
controls use power more efficiently than mechanical speed
controls so that the battery runs longer. An electronic speed
control also has circuitry that prevents loss of steering and
throttle control as the battery loses its charge.
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.
Neutral position - The standing position that the servos seek
when the transmitter controls are at the neutral setting.

E-REVO BRUSHLESS • 9
TRAXXAS TQ i RADIO SYSTEM
To prevent loss of radio range
do not kink or cut the black wire,
do not bend or cut the metal tip,
and do not bend or cut the white
wire at the end of the metal tip.
Correct NoNo No
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.
Resistance - In an electrical sense, resistance is a measure of how
an object resists or obstructs the flow of current through it.
When flow is constricted, energy is converted to heat and is
lost. Traxxas power systems are optimized to reduce electrical
resistance and the resulting power-robbing heat.
Rotor - The rotor is the main shaft of the brushless motor.
In a brushless motor, the magnets are mounted to the
rotor, and the electromagnetic windings are built into the
motor housing.
Sensored - Sensored refers to a type of brushless motor that
uses an internal sensor in the motor to communicate rotor
position information back to the electronic speed control.
Sensorless - Sensorless refers to a brushless motor that uses
advanced instructions from an electronic speed control to
provide smooth operation. Additional motor sensors and wiring
are not required.
Servo - Small motor unit in your model that operates the
steering mechanism.
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 electronic speed control detect overloading and
overheating of the transistor circuitry. If excessive temperature is
detected, the unit automatically shuts down to prevent damage
to the electronics.
2-channel radio system - The TQi radio system, consisting of
the receiver, the transmitter, and the servos. The system uses two
channels: one to operate the throttle and one to operate
the steering.
Voltage - Voltage is a measure of the electrical potential
difference between two points, such as between the positive
battery terminal and ground. Using the analogy of the garden
hose, while current is the quantity of water flow in the hose,
voltage corresponds to the pressure that is forcing the water
through the hose.
IMPORTANT RADIO SYSTEM PRECAUTIONS
• Do not kink the receiver’s antenna wire. Kinks in the antenna wire
will reduce range.
• DO NOT CUT any part of the receiver’s antenna wire. Cutting the
antenna will reduce range.
• Extend the antenna wire in the model as far as possible for
maximum range. It is not necessary to extend the antenna wire out
of the body, but wrapping or coiling the antenna wire should be
avoided.
• Do not allow the antenna wire to extend outside the body without
the protection of an antenna tube, or the antenna wire may get
cut or damaged, reducing range. It is recommended to keep the
wire inside the body (in the antenna tube) to prevent the chance
of damage.

If the status LED doesn’t light
green, check the polarity of
the batteries. If you see any
other flashing signal from the
LED, refer to the chart on page
32 to identify the code.
Use the Right Batteries
Your transmitter uses AA
batteries. Use new alkaline
batteries (part #2914). Do
not use rechargeable AA
batteries to power the TQi
transmitter, as they will not
provide sufficient voltage
for optimum transmitter
performance.
Caution: Discontinue running
your model at the first sign of
weak batteries (flashing red
light on the transmitter) to
avoid losing control.

TRAXXAS TQ i RADIO SYSTEM
INSTALLING BATTERY PACKS
The E-Revo requires two fully charged battery packs (not included).
Battery Installation
1. Open the battery compartment door by pressing on the release tabs.
2. Install the battery pack
with the battery wires
facing the rear of the
model.
3. Make sure the battery is
snug in the compartment.
If not, remove battery and
make adjustment to the
battery retaining tab.
4. Route the battery wire
through the slot near
the vent.
5. Close the battery door, making sure not to pinch the battery wires.
Be sure both release tabs are fully engaged with the door. Do not
connect the battery packs to the ESC at this time. Note: Always
unplug the batteries and remove from the model after use.
Using Different Battery Configurations
The battery compartments in the E-Revo are adjustable to accommodate
a large variety of battery packs. Depending on model, the battery
compartments are configured at the factory to accept either 7-cell
NiMH stick packs or 2-Cell LiPo battery packs. The E-Revo battery
compartments have three key features for keeping your batteries secure:
1. A foam rubber cushion
2. A spring clip (This is removable for use with taller batteries.)
3.
A battery retainer tab (This is adjustable to fit a variety of battery sizes.)
We recommend using this combination for all batteries. Make sure to
adjust the battery retainer tab to keep your battery pack snug against
the foam rubber cushion. This does not need to be very tight. It only
needs to prevent the battery from moving excessively during use.
6-cell battery packs:
Swap the battery retainer
tabs from the left and right
battery compartments.
This will provide additional
adjustment needed to keep
the 6-cell battery packs
snug against the foam
rubber cushions.
Adjusting Battery Position
The best handling and
performance is achieved
when the batteries are
positioned to the front of
the battery compartment
(against the foam rubber
cushion); however, you can
reposition the batteries
to change the weight distribution and handling if desired. The E-Revo
includes an extra set of battery retainer tabs that can be used in the
front of the battery compartment to move the batteries toward the rear
of the truck.
When using the battery retainer tabs in the front of the battery
compartment, use two 3x10 countersunk cap screws to retain each
battery retainer tab. Do not use the battery retainer tabs in the front of
the battery compartments when using LiPo batteries that are not in a
hard plastic case.
The battery compartments can be reconfigured to accept many sizes of
LiPo batteries. If you are using batteries that are very thick, the spring
clip may need to be removed from the battery compartment.
Spring Clip Removal
1. Pull down on the inside
of the clip.
2. Push the clip in toward
the center of the model
to release.

the chassis.
2. Rotate the spring clip
upward.
3. Snap the tabs into place.
Many LiPo batteries do not use a hard plastic case. If using LiPo
batteries that do not have a hard case, always be sure to use the foam
rubber cushion in the front of the battery compartment. Do not use
the battery retainer tabs in the front of the battery compartments
when using LiPo batteries that are not in a hard plastic case. A hard
front impact or crash when driving can damage the LiPo batteries.
RADIO SYSTEM RULES
• Always turn your TQi transmitter on first and off last. This procedure
will help to prevent your model from receiving stray signals
from another transmitter, or other source, and running out of
control. Your model has electronic failsafes to prevent this type of
malfunction, but the first, best defense against a runaway model is
to always turn the transmitter on first, and off last.
• Always use new batteries for the radio system. Weak batteries will
limit the radio signal between the receiver and the transmitter. Loss
of the radio signal can cause you to lose control of your model.
• In order for the transmitter and receiver to bind to one another,
the receiver in the model must be turned on within 20 seconds
of turning on the transmitter. The transmitter LED will flash fast
red indicating a failure to link. If you miss it, simply turn off the
transmitter and start over.
• Always turn on the transmitter before plugging in the battery.
RADIO SYSTEM BASIC ADJUSTMENTS
Throttle Neutral Adjustment
The throttle neutral adjustment is located on the
transmitter face and controls the forward/reverse
travel of the throttle trigger. Change the adjustment
by pressing the button and sliding it to the desired
position. There are two settings available:
50/50: Allows equal travel for both acceleration and reverse.
70/30: Allows more throttle travel (70%) and less reverse travel (30%).
Note: We strongly recommend to leave this control in its factory
location until you become familiar with all the adjustments and
capabilities of your model. To change the throttle neutral adjust
position, turn the transmitter off before adjusting the neutral position.
You will need to reprogram your electronic speed control to
recognize the 70/30 setting. Turn to 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.
Note: Traxxas Stability Management (TSM) must be completely
turned off while adjusting steering trim. See page 15 for TSM
adjustments.

Multi-Function Knob
The Multi-Function knob can be programmed
to control a variety of functions. From the
factory, the Multi-Function knob controls
Traxxas Stability Management (TSM). For more
detail on TSM, refer to page 15.
USING THE RADIO SYSTEM
The TQi Radio System has been pre-adjusted at the factory. The
adjustment should be checked before running the model, in case of
movement during shipping. Here’s how:
1. Turn the transmitter switch on. The status LED on the transmitter
should be solid green (not flashing).
2. Elevate the model on a block or a stand so that all the tires are
off the ground. Make sure your hands are clear of the moving parts
of the model.
3. Plug the battery packs in the model into the speed control.
4. Switch the speed control on. You will hear a short sequence of
tones as ALL the LEDs blink. The sequence will then repeat twice
more, then the YELLOW LED will remain illuminated. Always
disconnect your batteries when the model is not in use.
5. Turn the steering wheel on the transmitter back and forth and
check for rapid operation of the steering servo. Also, check that the
steering mechanism is not loose or binding. If the steering operates
slowly, check for weak batteries.
6. When looking down at model, the
front wheels should be pointing
straight ahead. If the wheels are
turned slightly to the left or right,
turn off TSM (see page 15) and
slowly adjust the steering trim
control on the transmitter until they are pointing straight ahead;
then, return the multi-function knob to the desired TSM setting.
7. Gently operate the throttle trigger to ensure that you have forward
and reverse operation, and that the motor stops when the throttle
trigger is at neutral. Warning: Do not apply full throttle in forward
or reverse while the model is elevated.
8. Once adjustments are made, turn the model off first (using the
switch on the speed control), then turn off the transmitter.
Range-Testing the Radio System
Before each running session with your model, you should range-test
your radio system to ensure that it operates properly.
1. Turn on the radio system and check its operation as described in
the previous section.
2. Have a friend hold the model. Make sure hands and clothing are
clear of the wheels and other moving parts on the model.
3. Walk away from the model with the transmitter until you reach the
farthest distance you plan to operate the model.
4. Operate the controls on the transmitter once again to be sure that
the model responds correctly.
5. Do not attempt to operate the model if there is any problem with
the radio system or any external interference with your radio signal
at your location.
Higher Speeds Require Greater Distance
The faster you drive your model, the more quickly it will near the limit
of radio range. At 60mph, a model can cover 88 feet every second! It’s
a thrill, but use caution to keep your model in range. If you want to see
your model achieve its maximum speed, it is best to position yourself in
the middle of the truck’s running area, not the far end, so you drive the
truck towards and past your position. In addition to maximizing the radio’s
range, this technique will keep your model closer to you, making it easier
to see and control. No matter how fast or far you drive your model,
always leave adequate space between you, the model, and others.
Never drive directly toward yourself or others.
TQi Binding Instructions
For proper operation, the transmitter and receiver must be
electronically ‘bound.’ This has been done for you at the factory.
Should you ever need to re-bind the system or bind to an additional
transmitter or receiver, follow these instructions. Note: The receiver
must be connected to a 4.8-6.0v (nominal) power source for binding
and the transmitter and receiver must be within 5 feet of each other.
1. Press and hold the transmitter’s SET button as you switch the
transmitter on. The transmitter’s LED will flash red slowly.
Release the SET button.
2. Press and hold the receiver’s LINK button as you switch on
the speed control by pressing the EZ-Set button. Release the
LINK button.
3. When the transmitter and receiver’s LEDs turn solid green, the
system is bound and ready for use. Confirm that the steering and
throttle operate properly before driving your model.
Using Reverse: While driving,
push the throttle trigger
forward to apply brakes.
Once stopped, return the
throttle trigger to neutral.
Push the throttle trigger
forward again to engage
proportional reverse.
TRAXXAS TQ i RADIO SYSTEM
Automatic Failsafe
The TQi transmitter and
receiver are equipped with
an automatic failsafe system
that does not require user
programming. In the event
of signal loss or interference,
the throttle will return to
neutral and the steering will
hold its last commanded
position. If failsafe activates
while you are operating
your model, determine the
reason for signal loss and
resolve the problem before
operating your model again.

TRAXXAS STABILITY MANAGEMENT (TSM)
Traxxas Stability Management or TSM
allows you to experience all the speed
and acceleration that was engineered
into your Traxxas model by helping
you to maintain control of the vehicle
in low-traction situations. TSM helps provide straight ahead full-
throttle acceleration on slippery surfaces, without fishtailing, spinouts,
or loss of control. TSM also dramatically improves braking control.
High speed cornering and control is also made possible as TSM
makes corrections for you, without intruding on your fun, or creating
unexpected side effects.
The Multi-Function knob on
the TQi transmitter has been
programmed to control TSM. The
recommended (default) setting
for TSM is to rotate the knob to
the 12:00 position (the zero mark
on the dial).
Turn the knob clockwise to
increase assistance; turn the knob
counterclockwise to decrease
assistance. Turn the
knob counterclockwise to its
stop to turn TSM completely off.
Note: TSM is deactivated
automatically when driving or
braking in reverse.
When driving on surfaces with some traction, decrease the TSM
setting to allow the vehicle to feel more “loose” for power sliding,
drifting, and so on. On surfaces with very little traction (loose dirt,
smooth concrete, ice/snow), increase TSM to maximize acceleration
and control.
Drive with TSM on and off to test how it is making your control of the
vehicle easier and more precise. For more information, visit Traxxas.
com/tsm.
Note: TSM must be completely turned off while adjusting steering
trim.
SETTING UP THE ANTENNA
The receiver antenna has been set up and
installed from the factory.
When reinstalling the antenna, first slide
the antenna wire into the bottom of the
antenna tube until the white tip of the
antenna is at the top of the tube under the
black cap. Insert the base of the tube into
the antenna post. Take care not to crimp the
antenna wire. Slide the crimp nut over the
antenna tube and screw it onto the antenna
post. 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 wire against the
chassis.
Do not bend or kink the antenna
wire! See the sidebar for more information.
Do not shorten the antenna tube.
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.

ADJUSTING ELECTRONIC
THE SPEED CONTROL
The MXL-6s electronic speed control should not need
reprogramming with normal use; however, if you install a different
radio system in your model, or change the transmitter’s throttle-
neutral setting from 50/50 to 70/30, you will need to reprogram the
speed control. Follow these instructions to reprogram the speed
control:
1. Install the batteries of your choice in the battery compartments
and plug the batteries into the speed control.
2. Switch on your transmitter.
3. Hold full throttle while you switch on the MXL-6s controller. After
a few seconds, you will hear multiple tones and the RED LED will
light.
4. Hold full brake. After a few seconds, you will hear multiple tones
and the YELLOW LED will light.
5. Release the trigger to the neutral position. After a few seconds,
you will hear multiple tones and ALL THE LEDs will light.
6. Wait a few more seconds for the speed control to ‘arm,’ indicated
by a double-tone. You are now ready to drive.
Disconnect Batteries After Use
Always disconnect the batteries from the speed control when
you are finished using your vehicle. The switch on the speed
control only shuts off power to the receiver and servos. The speed
control continues to draw power as long as it is plugged in and
may over-discharge your batteries if they are left connected to the
speed control.
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.
• Make Sure The Axle Nuts Are Tight Before Each Run
Before operating your E-Revo Brushless
Edition, take a moment to make sure
the axle nuts are tight, as they may have
loosened during shipping. The correct
size axle-nut wrench is supplied with
the truck. Check the tightness of the
axle nuts before each run. The E-Revo’s
high speed and torque can loosen the
nuts over time if left unchecked.
• Allow the model to cool for a few minutes between runs. This is
particularly important when using high capacity battery packs that
allow extended periods of running. Monitoring temperatures will
extend the lives of the batteries and motors.
• 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 motors. Remove the obstruction before continuing. Do not
push or pull objects with the model.
• Because the model is controlled by radio, it is subject to radio
interference from many sources beyond your control. Since radio
interference can cause momentary losses of control, allow a safety
margin of space in all directions around the model in order to
prevent collisions.
• Use good, common sense whenever you are driving your model.
Intentionally driving in an abusive and rough manner will only
result in poor performance and broken parts. Take care of your
model so that you can enjoy it for a long time to come.
• High performance vehicles produce small vibrations which may
loosen hardware over time. Frequently check wheel nuts and
other screws on your vehicle to ensure that all hardware remains
properly tightened.

E-REVO BRUSHLESS • 17
Slipper Clutch Break-In
The E-Revo Brushless Edition’s slipper clutch requires a break-in
procedure to ensure consistent operation with the extremely high
power output of the included MXL-6s brushless motor system. The
slipper clutch has been adjusted to the correct initial setting for
break-in. Follow these steps to ensure maximum performance and
life from your slipper clutch:
1. Make your first runs with the model using the stock gearing and
6- or 7-cell NiMH packs, or 2S LiPo packs.
2. Drive normally. The slipper clutch should slip momentarily when
accelerating aggressively on high-traction surfaces (you will hear
a whirring sound when the slipper clutch allows the spur gear
to slip).
3. If excessive slippage is noticed (slipping that lasts for more
than 3 seconds under hard acceleration), or the slipper clutch
slips anytime the throttle is applied at any lever, stop driving
immediately. Let the slipper clutch cool for 10-15 minutes.
When the clutch is cool, test-drive the vehicle again. If you still
experience excessive slippage, allow the slipper to cool once
more, then tighten the slipper nut ¼ turn (turn the nut clockwise)
and repeat the break-in process. Do not adjust the slipper clutch
before it has cooled.
4. Continue to run the vehicle and monitor slipper clutch
performance as noted above, and readjust if necessary. When the
run is complete, the slipper should be fully broken in.
After break-in, the slipper clutch is ready for any type of driving,
with any batteries up to 6S Lipo. Set the slipper clutch so it only
slips for a moment (if at all) under hard acceleration in high-
traction conditions. If excessive slippage is noticed, stop driving
immediately. Continuing to drive with a loose slipper will cause
damage to the slipper unit. You must let the slipper cool down
to ambient temperature before tightening the slipper nut and
resuming driving.
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 3000mAh battery pack will theoretically
run twice as long as a 1500mAh sport pack. Because of the wide
variation in the types of batteries that are available and the methods
with which they can be charged, it’s impossible to give exact run times
for the model.
Another major factor that affects run time is how the model is driven.
Run times may decrease when the model is driven repetitively from a
stop to top speed and with repetitive hard acceleration.
Tips for Increasing Run Time
• Use batteries with the highest mAh rating you can purchase.
• Use a high-quality peak-detecting charger.
• Read and follow all maintenance and care instructions provided by
the manufacturer of your batteries and charger.
• Keep the MXL-6s cool. Get plenty of airflow across the ESC.
• Lower your gear ratio. Installing smaller pinion gears will lower
your gear ratio and cause less power draw from the motor and
batteries, and reduce overall operating temperatures. Always
replace both pinion gears together.
• Vary your speed. Continuous high-speed, high-gear running
shortens the run time on the E-Revo.
• 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 effect your top-speed performance.
The higher capacity battery packs experience less voltage drop under
heavy load than low mAh rated packs. The higher voltage potential
allows increased speed until the battery begins to become discharged.
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.
DRIVING YOUR MODEL

18 •E-REVO BRUSHLESS
• Not all batteries can be used in wet environments. Consult your
battery manufacturer to see if their batteries can be used in wet
conditions. Do not use LiPo batteries in wet conditions.
• The Traxxas TQi transmitter is not water resistant. Do not subject it to
wet conditions such as rain.
• Do not operate your model during a rain storm or other inclement
weather where lightning may be present.
• Do NOT allow your model to come in contact with salt water (ocean
water), brackish water (between fresh water and ocean water), or
other contaminated water. Salt water is highly conductive and highly
corrosive. Use caution if you plan to run your model on or near a
beach.
The cooling fan on the ESC is not water resistant. To avoid
damaging the fan, it must be removed prior to driving your
model in wet conditions. To remove the cooling fan:
1. Remove the cover from the receiver box
and unplug the connector.
2. Reinstall the receiver box cover.
Note: When reinstalling the receiver
box cover, ensure that the O-ring is
properly seated in the groove around
the receiver box (for more information,
see “Receiver Box: Maintaining a
Watertight Seal” on the page 19).
3. Remove the two 3x35mm cap screws
from the ESC mount. Remove the ESC
mount.
4. Release the two tabs on the side of the
fan shroud to remove it from the ESC.
5. Remove the fan from the shroud.
6. Reinstall the shroud on the ESC.
7. Reinstall the ESC mount over the ESC.
Secure the mount with the two 3x35mm
cap screws.
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 center-line, 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.
5. Use lower gearing (smaller pinion gears, as low as 9T or spur gear as
large as 54T) when running in mud, deep puddles, snow, or other
similar situations that will restrict the tires and put much higher
loads on the motor.
Motor Precautions
• Motor life can be greatly reduced in mud and water. If the motor gets
excessively wet or submerged, use very light throttle (run the motor
slowly) until the excess water can run out. Applying full throttle to a
motor full of water can cause rapid motor failure. Your driving habits
will determine motor life with a wet motor. Do not submerge the
motor under water.
• 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.
• Use special care when operating your model in muddy conditions.
Stop operating your model if it appears to be straining due to the
tackiness of the mud or build-up of mud on the chassis. Do not allow
mud to collect on the motor or pack around the motor.
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 a pressure washer or
other high pressure water. Avoid directing water into the bearings,
differentials, etc.
DRIVING YOUR MODEL

E-REVO BRUSHLESS • 19
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 it 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.
• Differentials: Remove, disassemble, clean, and re-grease the
differential components. Use a light coating of wheel bearing
grease (from an auto parts store) on the metal gear teeth. Refer
to your exploded view diagrams for help with disassembly and
reassembly.
• Motor: After operating your model in wet or muddy conditions,
remove the motor and clean any mud or dirt from the bearings.
To access the rear bearing, remove the plastic cap with thumb
pressure, or gently pry the cap off with a flat-blade screwdriver.
To prevent corrosion and ensure maximum bearing life,
lubricate the bearings with a light oil (available at your local
hobby store). Following these steps will extend motor life and
maintain peak performance. 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 3x10mm 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 2.8x8mm cap screws.
4. Unplug the servo cables from the receiver and remove the receiver.
Receiver Installation
1. Always install the wires into the box
before installing the receiver.
2. Install the antenna wire and the servo
cables into the receiver box.
3. Arrange the wires neatly using the wire
guides in the receiver box. The excess
wire will be bundled inside the receiver box.
Label which wire is for which channel.
4. Apply small bead of silicone grease
(Traxxas part #1647) to the wire clamp.
5. Install the wire clamp and tighten the
two 2.8x8mm cap screws securely.
6. Using double-sided adhesive foam tape,
install the receiver into the box and plug
the wires into receiver. Refer to page 10
for the wiring diagram.
Note: For best performance, it is recommended that the receiver be
installed in the original orientation as shown.
7. 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 any way.
8. Install the cover and tighten the two 3x10mm button-head cap
screws securely.
9. Inspect the cover to make sure that the O-ring seal is not visible.

BASIC TUNING ADJUSTMENTS
This tuning and setup guide is separated into two sections- Basic and
Advanced. E-Revo does not require any specialized knowledge or
understanding of its unique suspension and drive train to perform
typical, everyday setup and track tuning adjustments. Adjustment
procedures for alignment, spring rate, damping, steering, and ride
height are covered in the basic tuning section. Adjustments for the
gear ratio, two-speed shift point, slipper clutch, and brake are also
covered. In most cases, the basic information is all that is needed to
tune E-Revo to perform well on a variety of surfaces.
E-Revo was engineered to provide sophisticated additional tuning
options well beyond the basics that allow expert users to extract
the maximum performance from the truck. The advanced tuning
section (beginning on page 27) covers topics such as optional
suspension rockers, roll center adjustment, caster adjustment, bump
steer tuning, differential setup, and fine tuning the two-speed
gear ratios. Make sure you fully understand the basic adjustments
before experimenting with the advanced adjustments. Improper
combinations of adjustments can adversely affect the performance of
the truck, resulting in poor handling. If you don’t know why you are
changing an adjustment then you should leave it at its factory setting.
Also included are instructions for using the Long-Travel rockers and
springs supplied with E-Revo. The long travel rockers allow extreme
suspension travel for rock crawling and rough, large-scale terrain. The
long travel rockers allow the suspension to operate at its extreme
mechanical limits and is recommended for advanced users.
SUSPENSION TUNING
Springs
The front and rear springs on E-Revo have different spring rates. The
rear springs are about 20% stiffer than the front springs. The
spring’s pre-load tension can be adjusted by turning the spring
pre-load adjuster. Adjusting the pre-load changes the suspension
sag. Suspension sag basically defines how much the suspension
compresses when the truck is at rest. Adjust the pre-load so that the
suspension compresses about one third of its full suspension travel
(see illustration). If suspension sag is severe and requires a large
increase of the spring pre-load to compensate, then a firmer spring
should be used. Firmer springs (supplied) must be used when the
Long Travel rocker arms are installed.
Use a stiffer spring to reduce sag, reduce body lean, control brake
dive, and provide a firmer, more responsive overall feel. If E-Revo is
lightened significantly
for racing applications,
softer springs will be
necessary to allow
the suspension to
sag properly. Heavier
configurations will
require stiffer springs.
Ride height is adjusted
by changing the length
or position of the
pushrods in the lower
suspension arms. See
the next section for ride
height adjustments. The suspension sag and spring pre-load should
be readjusted anytime the springs are removed and/or replaced.
Optional springs available from Traxxas are listed below. Refer to your
parts list for a complete part number listing. Higher rate springs are
stiffer. Springs can be identified by dots of color on one end.
Ride Height Adjustment
The rocker arm suspension uses push rods on each suspension arm.
Changing the length and/or position of the push rod adjusts the
ride height without affecting or compromising other suspension
parameters. For example, you can raise and lower the ride height
without changing up/down travel distribution, changing springs, or
affecting your progressive rate. This feature is unique to E-Revo and is
extremely beneficial in a racing environment where you can achieve a
low center of gravity (by lowering the ride height) without losing any
suspension capability. Increasing the ride height will increase ground
clearance for rough terrain.
