Safety Precautions

All instructions and precautions described in this manual must be strictly followed to ensure safe operation of your model. Failure to follow these instructions will be considered abuse or neglect.

Before operating your model, review this entire manual and carefully examine the model. If for any reason you decide it is not what you want, do not proceed in any way. Your dealer cannot accept a model for return or exchange if it has been operated.

Important Points to Remember

• Your model must not be operated on public roads or congested areas where its operation may conflict with or annoy pedestrians or vehicular traffic.
• Never, under any circumstances, operate the model among crowds of people. Your model is very fast and can cause injury if it collides with someone.
• Because your model is radio controlled, it is subject to radio interference from various sources beyond your control. Because radio interference can cause momentary loss of radio control, always allow a safe margin in all directions around the model to prevent collisions.
• The motor, battery, and speed control may become hot during use. Be careful to avoid burns.
• Do not operate your model at night or at any time when your line of sight to the model may be obstructed or diminished.
• Most importantly, use common sense at all times.

Speed Control

Your model's electronic speed control (ESC) is an extremely powerful electronic device capable of delivering high voltage. Follow these precautions carefully to avoid damage to the speed control or other components.

• Disconnect Battery: Always disconnect the battery or batteries from the speed control when not in use.
• Insulate Wires: Always insulate exposed wires with adhesive electrical tape to prevent short circuits.
• Turn on Transmitter First: Turn on the transmitter before turning on the speed control to prevent uncontrolled or erratic operation.
• Avoid Burns: The ESC and motor can become very hot during use, so do not touch them until they have cooled. Supply adequate airflow to allow for cooling.
• Use Factory-Installed Connectors: Do not change the battery or motor connectors. Incorrect wiring can cause the ESC to burn out or become damaged. Note that modified speed controls may be subject to a charge for re-wiring 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 reverse-speed controls. Using a Schottky diode with your Traxxas speed control will damage the ESC and void the 30-day warranty.
• Always comply with the minimum and maximum limits of the speed control as stated in the specifications table. If your ESC operates with two batteries, do not mix battery types or capacities. Use the same voltage and capacity for both batteries. Using mismatched battery packs could damage the batteries and the electronic speed control.

!WARNING! CAUTION! DANGER!

FIRE HAZARD!

This vehicle requires LiPo batteries. The process of charging and discharging batteries can cause fire, explosion, serious injury, and property damage if not performed according to the manufacturer's instructions. Furthermore, Lithium Polymer (LiPo) batteries represent a SERIOUS FIRE HAZARD if not handled properly according to instructions. Before use, read and follow all manufacturer's instructions, warnings, and precautions. LiPo batteries should only be used by advanced users who are familiar with the risks associated with using LiPo batteries. Traxxas does not recommend that any minor under the age of 14 use or handle them without the supervision of a responsible adult who is knowledgeable about the risks. Dispose of used batteries according to instructions.

• Your model requires the use of LiPo batteries. LiPo batteries have a minimum safe discharge voltage threshold that must not be exceeded. The electronic speed control is equipped with integrated Low-Voltage Detection that alerts the driver when the LiPo batteries reach their minimum (discharge) voltage threshold. It is the driver's responsibility to stop immediately to prevent the battery from discharging below the minimum safe threshold.
• Low-voltage detection in the speed control is only one part of a comprehensive plan for using LiPo batteries safely. It is important for you, the user, to follow all other instructions supplied by the battery manufacturer and the charger manufacturer for safely charging, using, and storing LiPo batteries. Be sure you understand how to use LiPo batteries. If you have questions about using LiPo batteries, consult your nearest local dealer or contact the battery manufacturer. As a reminder, all batteries must be recycled at the end of their useful life.
• Do not use a charger designed for NiCad or NiMH batteries. Using a NiMH or NiCad charger or charging mode will damage the batteries. Failure to use the correct charger may result in fire, personal injury, or property damage.
• ALWAYS carefully inspect LiPo batteries before charging. Do not use or charge damaged battery packs (bent, dented, swollen, torn covering, or otherwise damaged) in any way.
• BEFORE charging, ALWAYS confirm that the charger settings exactly match the battery type (chemical composition), specifications, and configuration of the battery being charged. DO NOT exceed the manufacturer's maximum charge rate. Do not attempt to charge non-rechargeable batteries (risk of explosion), batteries that have an internal charging circuit or protection circuit, or batteries that have been modified from the manufacturer's original configuration.
• During charging or discharging, ALWAYS place the battery (all battery types) in a fire-retardant/fire-proof container and on a non-flammable surface, such as concrete.
• ALWAYS charge batteries in a well-ventilated area.
• Charge the battery in a safe area away from flammable materials. Monitor the charging process. Always supervise batteries while they are charging and do not allow small children to charge or handle LiPo batteries.
• DO NOT disassemble, crush, short-circuit, or expose batteries or cells to flames or any other source of ignition.
• DO NOT allow exposed battery contacts or wires to touch each other. This will short-circuit the battery and create a fire hazard.
• ALWAYS supervise the charger and battery during charging, discharging, or any time the charger is ACTIVATED with a battery connected. If there are signs of malfunction, disconnect the power source or interrupt the charging process immediately.
• ALWAYS unplug the charger from the wall outlet and disconnect the battery when not in use.

Safety Precautions (Continued)

!WARNING! CAUTION! DANGER!

• Never charge LiPo battery packs in series or parallel. Charging batteries in series or parallel may result in incorrect charger cell recognition or incorrect charge rate, which may cause overcharging, imbalance, or cell damage, and fire.
• If, upon touching, a battery is hot during the charging process (temperature above 110°F/43°C), immediately disconnect the battery from the charger and discontinue charging.
• Do not store or charge LiPo batteries together with other batteries or near them, or with battery packs of any type, including other LiPo batteries.
• Store and transport your LiPo batteries in a cool, dry place. Store batteries away from direct sunlight. Do not allow storage temperature to exceed 140°F or 60°C, such as in a car trunk, as cells could be damaged and pose a fire risk. ALWAYS store battery packs safely out of reach of children and pets.
• Have a Class D fire extinguisher available in case of fire.
• DO NOT disassemble LiPo batteries or cells. DO NOT disassemble the charger.
• Do not attempt to build your own LiPo battery pack from loose cells.
• REMOVE batteries from your model or device before charging.
• DO NOT expose the charger to water or moisture.

Decal Application

The main decals for your model have been applied at the factory. Other decals are printed on clear, self-adhesive mylar and are die-cut for easy removal. Use a hobby knife to lift the corner of a decal and peel it from the backing paper.

To apply decals, place one end down, hold the other end up, and slowly slide your finger as you go. This will prevent air bubbles from forming. If you place both ends of the decal down and then try to slide your finger, air bubbles will form. Observe the box images for typical decal placement.

Introduction

Your model includes the latest 2.4 GHz Traxxas TQi transmitter with a Traxxas Link™ model memory. The transmitter's user-friendly design provides instant fun for R/C enthusiasts while also offering a complete complement of pro-level tuning features for advanced users or anyone interested in exploring their model's performance. Steering and throttle channels feature Exponential, End-Point, and Sub-Trims that are adjustable. Steering and brake Dual-Rate functions are also available. Many of the next-level functions are controlled by the multi-function knob, which can be programmed to control a variety of functions. The detailed instructions (page 36) and Menu Tree (page 39) included in this manual will help you understand and operate the advanced functions of your new TQi radio system. For more information and instructional videos, visit Traxxas.com.

Radio System Terminology

Take a moment to familiarize yourself with these terms related to the power and radio system. They will be used throughout the manual. A detailed explanation of the terminology and advanced functions of your new radio system begins on page 36.

• 2.4 GHz Spread Spectrum: This model is equipped with the latest R/C technology. Unlike AM and FM systems that require frequency crystals and tend to suffer from frequency conflicts, the TQi system selects an open frequency and automatically tunes to it, offering greater resistance to interference or "glitches."
• BEC (Battery Eliminator Circuit): The BEC can be found in the receiver or 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 4 AA battery pack to power the radio equipment.
• Brushless Motor: A DC brushless motor replaces the traditional commutator and brush arrangement of a brushed motor with smart electronics that power the electromagnetic windings in sequence to provide rotation. Unlike a brushed motor, the brushless motor has its windings (coils) on the perimeter of the motor case and the magnets are mounted on the rotor shaft.
• Preferred Endpoint Torque: Preferred endpoint torque is a condition sometimes associated with brushless motors. It is generally a slight oscillation felt when accelerating from a standstill. It occurs for a short period while the signals from the speed control and motor synchronize with each other.
• Current: Current is a measure of the flow of energy through electronic systems, generally measured in amperes. If you compare a wire to a garden hose, current is the measure of how much water flows through the hose.
• ESC (Electronic Speed Control): An electronic speed control is the electronic motor control within the model. Electronic speed controls use energy more efficiently than mechanical speed controls, so batteries last longer. An electronic speed control has circuitry that prevents loss of steering and throttle control as the battery loses its charge.
• Frequency Band: The radio frequency that the transmitter uses to send signals to your model. This model operates on a 2.4 GHz direct-sequence spread spectrum.
• kV Rating: Brushless motors are generally rated by their kV number. The kV rating is equal to no-load motor RPM per volt applied. kV increases as the number of turns of wire in the motor decreases. As kV increases, so does the current draw through the electronic systems.
• LiPo: Abbreviation for Lithium Polymer. Rechargeable LiPo battery packs are known for their special chemistry that allows for very high energy density and high current handling in a compact size. They are high-performance batteries that require special care and attention. LiPo battery packs are for advanced users only.
• mAh: Abbreviation for milliampere-hour, a measure of battery pack capacity. The higher the number, the longer the battery will last between charges.
• Neutral Position: The position of no movement that servos seek when the transmitter controls are in the neutral setting.

Traxxas TQi Radio System

NiCad:

Abbreviation for nickel-cadmium. Original NiCad rechargeable battery packs have high current handling, high capacity, and can last up to 1000 charge cycles. Good charging procedures are required to reduce the possibility of developing a "memory" effect and shorten run times.

NiMH:

Abbreviation for nickel-metal hydride. NiMH rechargeable batteries offer high-density current handling and much greater resistance to the "memory" effect. NiMH batteries generally allow for higher capacity than NiCad batteries. They can last up to 500 charge cycles. For optimal performance, a charger with a peak detector designed for NiMH batteries is required.

Receiver:

The radio unit within your model that receives signals from the transmitter and relays them to the servos.

Resistance:

In electrical terms, resistance is a measure of how an object resists or obstructs the flow of current through it. When flow is restricted, energy is converted to heat and lost. Traxxas power systems are optimized to reduce electrical resistance and the resulting heat that robs energy.

Rotor:

The rotor is the main shaft of the brushless motor. In a brushless motor, magnets are mounted to the rotor, and the electromagnetic windings are incorporated into the motor housing.

Sensored:

Sensored refers to the type of brushless motor that uses a sensor in the motor to communicate rotor position information to the electronic speed control.

Sensorless:

Sensorless refers to a brushless motor that uses advanced instructions from an electronic speed control to provide constant operation. No other motor sensors or wiring are required.

Servo:

A small motor unit in your model that operates the steering mechanism.

Solder Tabs:

External, accessible contacts on the motor that allow for easy wire replacement.

Transmitter:

The portable radio unit that sends steering and throttle instructions to your model.

Trim:

The precision adjustment of the servos' neutral position that is made by adjusting the steering and throttle trim sliders located on the front of the transmitter.

Thermal Shutdown Protection:

The electronic system that detects temperature, used in the speed control to detect overload and transistor circuit overheating. If excessive temperature is detected, the unit shuts down automatically to prevent damage to the electronic system.

2-Channel Radio System:

The TQi radio system, consisting of the receiver, transmitter, and servos. The system uses two channels: one to handle throttle and one to handle steering.

Voltage:

Voltage is a measure of the difference in electrical potential between two points; for example, between the positive battery terminal and ground. Continuing the garden hose analogy, while current is the amount of water flow in the hose, voltage corresponds to the pressure pushing the water through the hose.

Important Radio System Precautions

• Do not bend the receiver antenna wire. If you bend the antenna wire, range will be reduced.
• DO NOT CUT any part of the receiver antenna wire. If you cut the antenna, range will be reduced.
• Extend the antenna wire in the model as far as possible to achieve maximum range. It is not necessary to extend the antenna wire beyond the body, but avoid coiling or looping the antenna wire.
• Do not allow the antenna wire to extend outside the body without the protection of an antenna tube, as the antenna wire could be cut or damaged, reducing range. It is recommended to keep the wire inside the body (in an antenna tube) to prevent possible damage.

Your transmitter uses AA batteries. Use new alkaline batteries. Do not use rechargeable AA cells to supply current to the transmitter, as they will not provide sufficient voltage for optimal transmitter performance.

Caution: Stop driving your model at the first sign of low battery power (flashing red light) to avoid losing control of the model.

Traxxas TQi Radio System

iD Battery

Traxxas-recommended battery packs are equipped with Traxxas battery iD. This exclusive feature allows Traxxas battery chargers (sold separately) to automatically recognize connected battery packs and optimize charge settings for the battery. This eliminates the need to worry about charger menus and settings to obtain the simplest and safest charge solution possible. Go to Traxxas.com for more information about this feature and to view available Traxxas chargers and batteries with iD.

Traxxas High-Current Connector

Your model is equipped with the Traxxas high-current connector. Standard connectors restrict current flow and cannot supply the necessary power to maximize the VXL-6s output. The gold-plated terminals of the Traxxas connector with large contact surfaces ensure positive current flow with the lowest degree of resistance. Secure, durable, and easy to handle, the Traxxas connector is designed to extract all the power the battery can deliver.

Battery Pack Installation

The E-Revo requires two fully charged battery packs. These batteries are included with the model.

Battery Installation

1. Press the release tabs to open the battery compartment door.
2. Install the supplied batteries so that the battery wires are oriented toward the rear of the model.

Battery Wire Slot

3. Ensure the battery is secured in the compartment. If not, remove the battery and adjust the battery retention tab.
4. Guide the battery wire through the slot located near the opening.
5. Close the battery door; be sure not to pinch the battery wires. Ensure that both release tabs are fully engaged with the door. Do not connect the battery packs to the EVX-2 at this time. Note: Always disconnect and remove batteries from the model after each use.

Using Different Battery Configurations

The battery compartments in the E-Revo VXL are adjustable to accommodate a wide variety of battery packs. The battery compartments have three key features to hold batteries in place:

1. A polyurethane foam cushion
2. Springs in the battery compartment
3. Battery retainers

Use any combination of these features to prevent batteries from moving excessively during use.

Adjusting Battery Position

For optimal handling and performance, batteries should be located at the front of the battery compartment (against the polyurethane foam cushion). However, you can change the battery position to modify handling and weight distribution, if desired. The E-Revo includes battery retainers that can be used at the front of the battery compartment to move batteries toward the rear of the truck.

When using battery retention tabs at the front of the battery compartment, use two 3x10 countersunk screws to retain each battery retention tab. Do not use battery retention tabs at the front of battery compartments when using LiPo batteries that are not in a hard plastic case. A head-on impact or collision while driving can damage LiPo batteries.

Battery compartments can be reconfigured to accept many LiPo battery sizes. If you use batteries that are too wide, you may need to remove the spring retainer from the battery compartment.

Installing the Spring Retainer

1. Insert the two tabs into the spring retainer within the rectangular slots in the chassis.
2. Rotate the spring retainer upward.
3. Engage the tabs into place.

Removing the Spring Retainer

1. Pull down on the inside of the retainer.

Traxxas TQi Radio System

Radio System Rules

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

[Diagram: Transmitter Power-On Sequence]

• Always use new batteries for the radio system. Low-battery power will limit the radio signal between the receiver and transmitter. Loss of radio signal can cause you to lose control of your model.
• For the transmitter and receiver to bind to each other, the receiver in the model must be powered on within 20 seconds of turning on the transmitter. The transmitter's LED will flash red rapidly, indicating a connection failure. If you lost connection, simply turn off the transmitter and start over.
• Always turn on the transmitter before connecting the battery.

Basic Radio System Adjustments

The throttle neutral adjustment is located on the face of the transmitter and controls the forward/reverse travel of the throttle trigger. To change the adjustment, press the button and slide it to the desired position. Two settings are available:

• 50/50: Allows equal travel for throttle and reverse.
• 70/30: Allows greater throttle travel (70%) and less reverse travel (30%).

Note: We strongly recommend leaving this control at the factory setting until you become familiar with all of the model's adjustments and capabilities. To modify the throttle neutral adjustment position, turn off the transmitter before adjusting the neutral position. You will need to reprogram your electronic speed control to recognize the 70/30 setting. Refer to page 18 for instructions.

[Diagram: Transmitter Controls - Forward, Reverse, Neutral]

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

Immediately stop the model at the first sign of low battery power. Do not turn off the transmitter with the batteries connected. The model could run out of control.

Traxxas TQi Radio System

Reverse Operation

While driving, push the throttle trigger forward to brake. Once stopped, return the throttle trigger to neutral. Push the throttle trigger forward again to engage proportional reverse.

Failsafe Test

The TQi transmitter and receiver are equipped with an automatic failsafe system that requires no programming by the user. In the event of a signal loss or interference, the throttle will return to neutral, and the steering will hold the last commanded position. If the failsafe system activates while driving your model, determine the reason for the signal loss and resolve the problem before driving your model again.

Steering Trim

The electronic steering trim located on the front 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. Refer to page 17 to adjust TSM.

Multi-Function Knob

The multi-function knob can be programmed to control a variety of functions. As factory-set, the multi-function knob controls Traxxas Stability Management (TSM). For more details on TSM, refer to page 17.

Using the Radio System

The TQi radio system has been pre-adjusted at the factory. Adjustments should be checked before operating the model in case any shifting occurred during shipping. They should be checked as follows:

1. Turn on the transmitter. The transmitter's status LED should be solid green (not flashing).
2. Elevate the model on a block or platform so that no wheels touch the ground. Ensure your hands are clear of the model's moving parts.
3. Connect the model's battery packs to the speed control.
4. The power switch is built into the speed control. With the transmitter on, press and release the EZ-Set button (0.25 seconds). The LED lights green. This powers on the model. To turn off the VXL-6s, press the EZ-Set button until the light turns off (0.5 seconds).
5. Turn the steering wheel back and forth on the transmitter and check for quick steering servo operation. Also check that the steering mechanism is not loose or binding. If steering operates sluggishly, check the battery charge level.
6. When looking at the model, the front wheels should point straight ahead. If the wheels are slightly turned left or right, turn off the TSM (see page 17) and slowly adjust the steering trim control on the transmitter until they point straight ahead, then restore the desired TSM setting.
7. Smoothly operate the throttle trigger to ensure you have forward and reverse, and that the motor stops when the throttle trigger is in the neutral position. WARNING: Do not apply full throttle in forward or reverse while the model is elevated.

After making adjustments, turn off the receiver in your model and then the portable transmitter.

Radio System Range Check

Before each driving session with your model, you must range-check the radio system to ensure it operates correctly.

1. Turn on the radio system and verify its operation as described in the previous section.
2. Ask a friend to hold the model. Ensure hands and clothing are clear of the wheels and other moving parts of the model.
3. Walk away from the model with the transmitter until you have reached the farthest distance from which you plan to operate the model.
4. Operate the controls on the transmitter again to ensure the model responds correctly.
5. Do not attempt to operate the model if there is any problem with the radio system or if there is any external interference with your radio signal at your location.

Higher Speeds Require Greater Distances
The faster you drive your model, the quicker you will reach the radio's range limit. At 60 mph, a model can cover 88 feet (approximately 27 meters) per second. It's exciting, but you must be careful to keep your model within range. If you want to see your model reach its top speed, it is best to position yourself in the middle of the truck's running area, not at one end, so that you can drive the truck toward and past your location. In addition to maximizing radio system 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 plenty of space between yourself, the model, and other people. Never drive the model directly toward yourself or other people.

TQi Binding Instructions

For proper operation, the transmitter and receiver must be electronically "bound." This is done at the factory. If you ever need to re-bind the system or bind it to another transmitter or receiver, follow these instructions. Note: The receiver must be connected to a 4.8 to 6V (nominal) power source for binding, and the transmitter and receiver must be within 5 feet (approximately 1.5 meters) of each other.

1. Press and hold the transmitter's SETUP button while turning on the transmitter. The transmitter's LED will flash red slowly. Release the button.
2. Press and hold the receiver's BIND button while turning on the speed control (by pressing the EZ-Set button). Release the BIND button.
3. When both the transmitter and receiver LEDs light green, the system is bound and ready for use. Verify that steering and throttle operate correctly before driving the model.

Traxxas TQi Radio System

Traxxas Stability Management (TSM)

Traxxas Stability Management, or TSM, allows you to enjoy all the speed and acceleration your Traxxas model was designed for, helping you maintain traction in slippery conditions. TSM helps provide full-throttle acceleration on slick surfaces without fishtailing, loss of control, or spinouts. TSM also significantly improves braking control. It also makes it possible to take corners and maintain high-speed control, as TSM makes corrections for you, without interfering with 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 turn the multi-function knob to the 12:00 position (the zero mark on the dial).

• Turn the knob to the right to increase assistance; turn the knob to the left to decrease assistance. Turning the knob all the way to the left turns TSM completely off.
• Note: TSM automatically disengages when driving or braking in reverse.

[Diagram: TSM Adjustment Knob Settings]

When driving on surfaces with some traction, you may want to reduce the TSM setting to allow the vehicle to feel "looser" for varied slides and power variations, 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 makes controlling your vehicle easier and more precise. For more information, visit Traxxas.com/tsm.

Note: Traxxas Stability Management (TSM) must be completely turned off while adjusting steering.

Antenna Setup

The receiver antenna was configured and installed at 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 onto the antenna post. Be careful not to pinch the antenna wire. Slide the nut over the antenna tube and thread it onto the antenna post. Use the supplied tool to adjust the nut on the post until the antenna tube is securely in place. Do not overtighten or pinch the antenna wire against the chassis. Do not bend or twist the antenna wire. Refer to the side column for more information. Do not shorten the antenna tube.

[Diagram: Antenna Assembly]

[Diagram: Correct vs. Incorrect Antenna Wire Handling]

Auto-Leveling

Your model is equipped with Traxxas Auto-Leveling, which allows it to automatically return to an upright position after a flip. Ensure there is sufficient space around your E-Revo and that no people or animals are near the auto-leveling system. The model moves quickly and the tires spin at high speed. If someone or an animal approaches the model during auto-leveling, immediately cancel it by moving the steering wheel or throttle trigger. Press and hold the SETUP button on the transmitter for four (4) seconds to activate the auto-leveling function. Once activated, release the SETUP button.

Note: Certain surfaces or driving conditions may prevent the model from self-righting. After several attempts, auto-leveling will cancel. Press the SETUP button to try again or go and retrieve your model.

Auxiliary Power Panel

The VXL-8 electronic speed control is equipped with a power panel that can be used to power optional accessories, such as LED light kits or additional cooling fans (see Traxxas.com for more information). Always ensure the panel cover is installed when accessories are not in use to protect the pins from damage.

Adjusting the Electronic Speed Control

Protection Modes and LED Codes

The VXL-6s electronic speed control (ESC) is equipped with sophisticated circuitry designed to help protect the electronic system from damage caused by overload and excessive temperatures. When a protection circuit is activated, the LED on the VXL-6s will light up to indicate the fault.

ESC Protection Modes and Solutions

• Solid Green: VXL-6s power light. Low-voltage detection is ACTIVATED (LiPo configuration).
• Solid Red: VXL-6s power light. Low-voltage detection is DISABLED (NiMH configuration).
• Solid Red LED for Current (A): The VXL-6s has entered Stage 1 overcurrent protection. When excessive current (amperage) was being directed through the power system due to a failure to use the proper gear ratio for the drivetrain and driving surface, the VXL-6s will limit power output to 50% of acceleration. Ensure your model has the correct gearing for the conditions. Before continuing, inspect the vehicle for any damage. To reset, turn off the ESC and turn it back on.
• Rapid Red LED Flash for Current (A): The VXL-6s has entered Stage 2 overcurrent protection. When current flow temporarily spikes due to a stall or a restricted drive-line (i.e., the model became stuck against an object or encountered a restricted drive-line surface), the VXL-6s will automatically shut down (failsafe mode). Stop driving the model. The VXL-6s will remain in this mode until current flow recovers (obstruction removed, model moved to a smoother driving surface), and the throttle returns to neutral. To reset, turn off the ESC and turn it back on.
• Solid Red LED for Voltage (V): The VXL-6s has entered low-voltage protection, Stage 1. When battery voltage begins to reach the minimum recommended discharge voltage threshold for LiPo batteries, the VXL-6s will limit power output to 50% acceleration. Stop driving the model. The VXL-6s will remain in this mode until battery voltage recovers or two fully charged batteries are connected.
• Slow Red LED Flash for Voltage (V): The VXL-6s has entered low-voltage protection, Stage 2. When battery voltage attempts to drop below the minimum threshold, the VXL-6s will automatically lock up (failsafe mode). The LED on the speed control will flash slowly red, indicating a low-voltage lockout. Stop driving the model. The VXL-6s will remain in this mode until two fully charged batteries are connected.

Adjusting the Electronic Speed Control

• Rapid Red LED Flash for Voltage (V): If the motor has no power, the VXL-6s has entered over-voltage protection. When the battery voltage of the connected battery packs is too high, the VXL-6s enters a failsafe mode. WARNING: If input voltage exceeds approximately 25.2 volts (12.6 per battery pack), the ESC may be damaged. Do not exceed the total peak input voltage of 25.2. Stop driving the model, turn off the ESC, and disconnect the batteries.
• Solid Red LED for Temperature (៛): The VXL-6s has entered thermal protection, Stage 1, due to excessive current flow. The VXL-6s will limit power output to 50% acceleration. Stop driving the model. Inspect the ESC fan to ensure it is operating. Allow the power system to cool before continuing.
• Rapid Red LED Flash for Temperature (): The VXL-6s has entered thermal protection, Stage 2, and has automatically shut down (failsafe mode). Stop driving the model. Inspect the ESC fan to ensure it is operating. Allow the power system to cool before continuing. Frequent warnings about excessive temperature may be caused by excessive gearing (aftermarket), continuous and highly aggressive high-speed driving, vehicle damage, or driving in conditions such as deep sand, heavy mud, and tall grass.
• Solid Red LED for Current/Voltage/Temperature or Rapid Red Flash for All LEDs: The VXL-6s has entered this protection mode due to the possibility of thermal protection and low-voltage protection (see above) occurring at the same time, or if there is a critical malfunction or programming error. Turn off the ESC and contact Traxxas customer service for assistance.

Driving Your Model

It's time for fun! This section contains instructions on how to drive your model and how to make adjustments. Before continuing, read the important precautions below.

• Ensure Wheel Nuts Are Tight Before Each Run
  Before operating your E-Revo VXL brushless, take a moment to ensure the wheel nuts are tight, as they may have loosened during shipping. The correct wheel nut wrench size is provided with the truck. Check the tightness of the wheel nuts before each run. The E-Revo's high speed and torque can loosen the nuts over time if they are not checked.
• Allow the model to cool for a few minutes between runs. This is especially important when using high-capacity battery packs to allow for extended run periods. Controlling temperatures will prolong the life of your batteries and motors.
• Do not continue to operate the model on low battery power, or you may lose control of it. Some indications of low battery power are sluggish operation and slow servos (slow to return to center). Stop immediately at the first sign of low battery power. When the transmitter batteries lose power, the red power light will begin to flash. Stop immediately and install new batteries.
• Do not drive the model at night, on public roads, or around large crowds of people.
• If the model stops on an object, do not continue to operate the motors. Remove the object before continuing. Do not push or pull objects with the model.
• Because the model is radio controlled, it may be affected by radio interference from various sources beyond your control. Because radio interference can cause momentary loss of radio control, always allow a safe margin in all directions around the model to prevent collisions.
• Use common sense whenever you operate your model. The only results of intentionally abusive and violent driving will be poor performance and damaged parts. Take care of your model so you can enjoy it for a long time.
• High-performance vehicles produce slight vibrations that can loosen parts over time. Frequently check wheel nuts and other screws on your vehicle to ensure parts remain tight.

Run Time Considerations

An important factor affecting run time is the type and condition of the batteries. The milliampere-hour (mAh) rating of the batteries determines how long the model runs on a full charge. A 3000 mAh battery pack will theoretically run twice as long as a 1500 mAh battery pack. Due to the wide variety of battery types available and charging methods, it is impossible for us to inform you of your model's exact run time.

Another important factor affecting run time is the way your model is used. Run times can be reduced when the model is driven repeatedly from a standstill to maximum speed and with constant, abrupt acceleration.

Tips for Increasing Run Time

• Use batteries with the highest mAh capacity you can afford.
• Use a high-quality peak-detecting charger.
• Read and follow the battery and charger maintenance and care instructions supplied by the manufacturer.
• Allow the MXL-6s to cool. Supply adequate airflow to the ESC.
• Reduce the gear ratio. Installing a smaller pinion gear or a larger spur gear will reduce the gear ratio, which will reduce motor and battery consumption, and lower operating temperature. Replace both pinion and spur gears at the same time.
• Vary your speed. Continuous operation at high speed reduces the E-Revo's operating time.
• Maintain your model. Eliminate dirt and damaged parts that cause drivetrain binding. Keep the motor clean.

mAh Rating and Power Output

The battery's mAh rating can affect maximum speed performance. Higher-capacity battery packs suffer less voltage sag under heavy load than lower-capacity packs. Higher voltage potential allows for higher speed until the batteries begin to discharge.

Driving in Wet Conditions

Your 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 other wet conditions. Despite the high water resistance, the model should not be treated as if it were 100% submersible or fully waterproof. Water resistance applies only to the installed electronic components. Driving in wet conditions requires additional care and maintenance of mechanical and electronic components to prevent corrosion and maintain proper function.

• Without proper attention, some parts of your model may suffer serious damage from water contact. Know that additional maintenance procedures will be required after each run to maintain your model's performance. Do not operate the model in wet conditions if you are unwilling to perform the additional care and maintenance tasks.
• Not all batteries can be used in wet environments. Consult the manufacturer to see if your 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 expose it to wet conditions, such as rain.
• Do not operate your model during a thunderstorm or other inclement weather where lightning may occur.
• Do not allow your model to come into contact with salt water (seawater), brackish water (between fresh and seawater), or other contaminated water. Salt water is highly conductive and corrosive. Exercise caution if you plan to operate your model at or near the beach.

Before Operating Your Vehicle in Wet Conditions

1. Consult the "After Operating Your Vehicle in Wet Conditions" section before proceeding. Ensure you understand the additional maintenance that must be performed after operating the vehicle in wet conditions.
2. The wheels have small molded holes to allow air in and out during normal use. Water will enter through these holes and become trapped in the tires if you do not cut these holes. Cut two small holes (3 mm or 1/8 inch diameter) in each tire. Each hole should be near the center line of the tire, with 180 degrees of separation.
3. Confirm that the receiver box O-rings are installed correctly and securely. Ensure that the screws are tight and that the blue O-ring does not protrude visibly 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 11T, or larger spur gears as high as 54T) when driving in mud, deep puddles, snow, or other similar situations that will limit the tires and place much greater loads on the motor.

Note: To prevent damage to your vehicle's electronic components while operating in soft sand, make the following minor modifications to the four-wheel and tire assemblies. Hold the wheel while cutting two small indentations with body scissors. Cut the indentations in a "V" pattern; then remove the cut material to create an approximately 1/8 in (3 mm) hole.

Motor Precautions

• Motor life can be greatly reduced in mud and water. If the motor becomes submerged or wet, apply slight throttle (so the motor runs slowly) until all excess water is expelled. Full throttle in a water-filled motor can cause it to fail rapidly. Your driving habits will determine the motor's life if it becomes wet. Do not submerge the motor in water.
• Do not gear the motor according to temperature when operating in wet conditions. The motor will cool from water contact and will not give an accurate indication of proper gearing.
• Exercise extreme caution when operating your model in mud. Stop operating your model if it seems to be straining due to the mud's stickiness or mud buildup on the chassis. Do not allow mud to get into the motor or build up around it.

After Operating Your Vehicle in Wet Conditions

1. Drain the tires by spinning them at high speed to expel water. One way is to make a few high-speed passes on a flat, dry surface.
2. Remove the batteries.
3. Rinse the truck to remove excess dirt or mud, which can be done with low-pressure water, such as from a garden hose. DO NOT use pressure washers or other high-pressure water sources. Avoid aiming water directly at the bearings, drivetrain, etc.

Receiver Box: How to Maintain a Watertight Seal

Radio Gear Extraction and Installation

The unique design of the receiver box allows for the extraction and installation of the receiver without losing the watertight seal in the box. The patented wire-catch feature also allows for the installation of aftermarket radio systems while maintaining the watertight functions of the receiver box.

Receiver Extraction

1. To remove the cover, remove the two 3x8mm countersunk screws.
2. To remove the receiver from the box, simply lift it and move it to the side. The antenna wire is still in the catch area and cannot be removed yet.
3. Remove the wire catch by removing the two 2.8x8mm screws.
4. Unplug the servo wires from the receiver and remove the receiver.

Receiver Installation

1. Always install the wires in the receiver box before installing the receiver.
2. Install the antenna wire and servo wires into the receiver box.
3. Carefully arrange the wires using the wire pass-through in the receiver box. Excess wire will be accommodated inside the receiver box. Label which wire corresponds to which channel.
4. Apply a small drop of silicone grease (Traxxas Part #1647) to the wire catch.
5. Install the wire catch and securely tighten the two 2.8x8mm screws.
6. Use double-sided tape to install the receiver in the box.

Note: For best performance, it is recommended that this receiver be installed in the original orientation as shown.

7. Plug the wires into the receiver. Refer to page 12 for the wiring diagram.
8. Ensure the O-ring is seated correctly in the receiver box groove so that the cover does not pinch or damage it in any way.
9. Install the cover and securely tighten the two 3x8mm countersunk screws.
10. Inspect the cover to ensure the O-ring seal is not visible.

Basic Precision Adjustments

Alignment Configurations

Alignment settings are fundamental to optimizing the E-Revo's performance. Adjust your alignment with as much care and precision as possible.

Camber/Toe Adjustment

The wheels can be adjusted to point straight ahead or to have toe-in or toe-out. To help you remember, look at your feet. For toe-in, your feet point inward. For toe-out, your feet point outward.

The front wheel toe angle can be adjusted by varying the length of the suspension arms that connect the steering linkage to the front axle carriers. The rear wheel toe angle can be adjusted by varying the length of the metal suspension arms that connect the rear bulkhead to the rear axle carriers. The front and rear suspension arms are equipped with turnbuckles. The lengths of the toe adjustment rods can be adjusted by turning them with the 5 mm wrench.

Factory Alignment Settings:
Front: 0 degrees
Rear: 1 degree of toe-in on each side

Static Camber Adjustment

The wheels can be set to have positive or negative camber (see illustration below). The camber angle changes as the wheels move up and down in their suspension travel. Static camber is the wheel angle when the vehicle is set at its normal, static ride height.

The pivot balls in the axle carriers adjust static camber. The pivot balls are protected by blue dust caps. To adjust your static camber, insert the supplied 2.5 mm hex wrench into the recess in the dust cap and engage the pivot ball end (compressing the suspension until the arms are parallel to the ground will allow the hex wrench to engage more easily). The upper pivot ball is generally fully threaded in. Negative camber is achieved by unscrewing the pivot ball from the lower control arm. Note: When changing camber, the wheel angle must be reset.

Factory Static Camber Settings:
Front: 1 degree negative camber on each side
Rear: 1 degree negative camber on each side

[Diagram: Positive and Negative Camber]

[Diagram: Alignment Settings - Front and Rear Wheels]

For caster angle and center of gravity, refer to Advanced Precision Adjustments on page 32.

An inclination gauge (available at your local dealer) can be a useful tool for setting inclination.

All suspension arms are installed on the truck so that the left-hand thread indicators point in the same direction. This makes it easier to remember which way to turn the wrench to increase or decrease the suspension arm length (the direction is the same on all four corners). Note that the slot in the hex unit indicates the side of the suspension arm that has the left-hand threads.

Basic Precision Adjustments

Maximum Alignment Limits (with Pushrod Length)

The E-Revo's maximum axle and toe alignment limits can be limited by adjusting the ride height. Do not exceed the maximum limits, or you may experience interference between suspension components. Ride height is controlled by the position in which the pushrod is installed in the lower suspension arm. First, determine which of the following configurations you are using:

• Standard Configuration: When the pushrod is in the middle position of the lower control arm.
• Raised Configuration: When the pushrod is in the raised position to increase the vehicle's ride height (innermost hole in the lower control arm).
• Lowered Configuration: When the pushrod is in the lowered position to decrease the vehicle's ride height (outermost hole in the lower control arm).

Front Suspension

The following maximum values are suggested for the front suspension to prevent interference between suspension components:

Rear Suspension

The following maximum values are suggested for the rear suspension for all configurations. Toe-out is not normally used on the rear of the E-Revo.

Wheels and Tires

Many types of aftermarket tires and wheels can be fitted to your model. Most will affect the overall width and suspension geometry of the model. The offsets and dimensions designed into the model's wheels are intentional; therefore, Traxxas cannot recommend the use of wheels other than Traxxas wheels that feature different specifications. Wheel diameter is an innovative design, and a variety of different tires are available for you to experiment with, in addition to the tires included with the model (listed in your parts list). It is recommended to experiment with different tire types to see which ones work best on the terrain where the model is operated. When selecting tires, consider the overall diameter and rubber compound (hard or soft). If the overall tire diameter is significantly increased, you will need to use a smaller pinion gear to compensate for the larger tire. Softer compound tires with short, numerous lugs generally work best on hard, dry surfaces. On loose mud, tires with long lugs work best. Consult your parts list for optional wheels and tires.

Motors and Gearing

One of the most important advantages of your model's drivetrain is the wide variety of available gear ratios. Changing the gearing will allow you to adjust the model's speed and control battery and motor temperatures. Use a lower pinion gear (numerically higher) to reduce current draw and temperatures. Use a higher pinion gear (numerically lower) to increase top speed. Use the following formula to calculate the overall ratio for combinations not listed in the gear chart:

(Number of Teeth on Spur Gear) / (Number of Teeth on Pinion Gear) x 5.69 = Final Gear Ratio

When using higher pinion gear ratios, it is important to monitor battery, motor, and speed control temperatures. If the battery is extremely hot (150°F), or the motor is very hot to the touch (180°F), your model is likely geared too high and drawing too much current. This temperature test assumes the model has the approximate factory stock weight and is operating without restrictions or excessive friction, drag, or binding, and that the battery is fully charged and in good condition.

Basic Precision Adjustments

Motor and Gearing

This model is equipped with a 2200Kv brushless motor. The factory-installed gear combination on each model provides good overall acceleration and top speed. If you desire higher top speed and less acceleration, install the optional high-speed gear (more teeth). If you desire more acceleration and less top speed, use an optional smaller pinion gear (not included). Optional gears not included.

Note: The included high-speed gear is intended for high-speed running on hard surfaces and is not recommended for off-road or constant starting and stopping. For this type of driving, smaller pinion gears are recommended to reduce load on the motor.

Pinion Gear Adjustment

Incorrect pinion gear installation is the most common cause of spur gear failure. The E-Revo VXL brushless makes improper gear mesh virtually impossible. A factory-installed fixed gear adapter helps secure the motor in place according to the pinion gear and spur gear selected. Access the gears by removing the top cover screw.

If you choose to do so, you can also set up the gear mesh manually without using the fixed gear adapter. With the adapter removed, cut a thin strip of notebook paper and place it in the mesh of the motor gear. The motor is installed in an aluminum motor mount. Loosen the single screw in the motor mount with the supplied 3 mm wrench to slide the motor mount. Slide the motor and pinion gear forward. Retighten the motor mount screw and then remove the paper strip. You should be able to place a new strip of paper between the gears without causing binding.

Basic Precision Adjustments

Dual Servo Steering System

The E-Revo uses dual servos and a single heavy-duty servo saver for powerful, responsive steering. To prevent unnecessary drain on the receiver battery, it is important to ensure the servos are "at rest" when the steering is at neutral. If one servo is out of adjustment, the two servos will fight each other, struggling to find center.

Steering System Adjustment

1. Remove the servo horns and steering rods from the servos. Disconnect the steering rods from the servo saver.
2. Adjust the two steering rods to have the same length (31.7 mm; use the "Steering Rod Length Template" to set the length).
3. Power the transmitter and receiver.
4. Turn off TSM (see page 17).
5. Adjust the steering trim on the transmitter to the "0" neutral position.
6. Connect one end of the steering rod to the steering servo saver arm and the other end to the servo horn.
7. Position the steering servo saver arm perpendicular to the vehicle's centerline.
8. While holding the steering servo saver arm in the position mentioned in Step 6, install the servo horn onto the servo so that the steering rod is parallel to the vehicle's centerline. This will automatically set the servo horn to the 7-degree tilt shown in the illustration.
9. Install the second servo horn on the other side following the same procedure.

If necessary, precisely adjust the length of the second steering rod to eliminate any load on the steering system at the neutral position. If you are using aftermarket servos, it is important to use E-Revo-specific servo horns. Optional steering servo horns are sold separately for use with non-Traxxas servos.

Servo Saver Adjustment

A stiffer optional spring is available for the servo saver when using servos with metal gearsets (refer to the parts list for details). Do not use this spring with Traxxas's high-torque standard servos.

Maintenance of Your Model

Your model requires timely maintenance to remain in optimal operating condition. The following procedures should be taken seriously.

• Inspect the model for obvious damage or wear. Consider the following aspects:
• 1. Broken, bent, or damaged parts.
• 2. Check wheels and steering for binding.
• 3. Check shock absorber operation.
• 4. Check wires for frayed wires or loose connections.
• 5. Check receiver and servo mounting, and speed control mounting.
• 6. Check tightness of nuts with a wrench.
• 7. Check radio system operation, especially battery status.
• 8. Check for loose screws in the chassis structure or suspension.
• 9. Inspect gears for broken teeth or debris lodged between teeth.
• 10. Check steering servo operation and ensure they are not binding.
• 11. Check pivot ball tightness.

Other Periodic Maintenance Tasks:

• Damper Gear Mechanism: The damper gear mechanism does not require maintenance but should be inspected periodically. If the damper gear mechanism develops play (the spur gear's movement does not drive the transmission shaft), disassemble the damper gear mechanism and inspect the elastomer (Part #6465X) for damage and replace if necessary.

• Chassis: Keep the chassis free of accumulated dirt and grime. Periodically inspect the chassis for damage.
• Shock Absorbers: Maintain full oil level in the shock absorbers. Use only 100% pure silicone shock absorber oils to prolong seal life. If you have leaks from the top of the shock absorber, inspect the chamber in the upper cap for signs of damage or distortion due to overtightening. If the bottom of the shock absorber leaks, it is time for a rebuild. The Traxxas rebuild kit for two shock absorbers is Part #5462.
• Suspension: Periodically inspect the model for signs of damage, such as bent or dirty suspension pins, bent turnbuckles, loose screws, and any sign of a part being stressed or bent. Replace components as needed.
• Drivetrain System: Inspect the driveshafts to ensure the pins are not cracked or excessively worn. If drivetrain components are worn, additional noises may occur in the drivetrain. Remove the gear cover. Inspect the spur gear for wear and check the tightness of the set screws on the pinion gears. Adjust, clean, and replace components as needed.
• Torque-Biasing Center Unit: The E-Revo VXL is equipped with a torque-biasing center unit. The deviation unit can be rebuilt, but it requires detailed maintenance procedures and the use of 20MM differential oil (Part #5040). For more information and instructional videos, visit Traxxas.com.

Storage

When you finish using the model for the day, dry it with compressed air or use a soft bristle brush to remove dust from the vehicle. Always disconnect and remove batteries from the model when the model is stored. If the model will be stored for a long period, then also remove the transmitter batteries.

[Warning Icon] Use eye protection when using compressed air or aerosol cleaners and lubricants.

Alignment and Suspension Configurations

Caster Angle Adjustment

The caster angle of the front suspension can be used to regulate the model's understeer (push)/oversteer handling characteristics. Generally, increasing the caster angle will bring the truck closer to an oversteer condition (more traction at the front tires, less at the rear tires). Decreasing the caster angle will cause the tendency to be toward understeer (push in the turns). At the factory, the front suspension is set to a 10-degree caster angle. The rear axle caster angle cannot be adjusted.

The front suspension caster angle can be adjusted from 5 to 15 degrees. To adjust the caster angle, locate the caster adjustment shims in the front upper control arms as shown in the table to the right.

[Diagram: Caster Adjustment Shims]

Impact Steering

Impact steering is the unwanted change in the front wheel steering angle as the suspension moves up and down. It can result in unstable and unpredictable handling. Impact steering is affected by the position of the suspension arm's outer end in the axle carrier. At the factory, the suspension arms are positioned to virtually eliminate impact steering (approximately 3/100 of a degree through the entire range of travel). When changing the caster angle, the outer suspension arm end must be repositioned in the axle carrier to maintain zero impact steering geometry. Adjustment is achieved by using the shims and hollow balls (Parts #5355 and #5347, sold separately). Refer to the Impact Steering Elimination chart on page 33 and look up your caster angle configuration to find the correct position for the outer suspension arms. Correctly positioning the suspension arms will maintain the original factory geometry and eliminate unwanted changes in steering angle caused by impact steering.

Center of Gravity

There are two holes in the bulkheads for mounting each upper suspension arm. The vehicle's center of gravity can be raised by mounting the upper control arm in the lower of the two holes. This will effectively increase the vehicle's roll stiffness (similar to installing sway bars). Adding roll stiffness to one end of the vehicle will add traction to the opposite end. For example, increasing rear-end roll stiffness by installing the upper arms in the lower holes will provide more front-tire traction and potentially more steering. Installing the upper arms in the lower holes at the rear and front will increase overall roll stiffness without altering the handling balance. At the factory, the arms are installed in the upper position to make the truck easier and more flexible to drive and to provide less chance of traction roll in turns. The lower holes should be reserved for adjustments. Note: When moving the upper suspension arms to the lower holes, the outer suspension arm ends and rear control arms must be repositioned to eliminate impact steering. Refer to the Impact Steering Elimination chart on page 33 and look up your suspension combination (caster angle and center of gravity position) to find the correct position for the outer suspension arms and rear control arms. Adjustment is achieved by using the shims and hollow balls provided with the vehicle.

Rockers (Suspension Travel/Progressive Rate)

One of the E-Revo's most exciting features is the internal shock absorber arrangement that uses pivoting rockers to convert the wheel's vertical travel into linear shock absorber motion. The rockers can be changed to increase or decrease maximum wheel travel and also to modify the suspension's progressive rate. The progressive rate determines how much the force on the wheel will vary with suspension compression (or vertical wheel travel). In a progressive suspension arrangement, the wheel force will increase at an increasingly faster rate as the suspension compresses. It feels as though the shock absorber spring is getting progressively stiffer the more the suspension compresses. In a linear suspension arrangement, wheel force increases linearly as the suspension compresses. The spring does not feel stiffer, even when the suspension is fully compressed. This provides a suspension that feels "plush" with seemingly endless suspension travel. A total of three sets of rocker arms are available for the E-Revo VXL. All rockers will allow the wheel to travel a total of 90 mm vertically.

[Diagram: Rocker Arm Chart]

Shock Piston Hole Sizes

• Piston 1: 1.10 mm
• Piston 2: 1.00 mm
• Piston 3: 0.95 mm

[Warning Icon] Never slide the threads over the shock shaft through the square-section seal when it is installed and compressed by the lower cap. This will damage the seal and cause shock oil leakage.

Shock Piston Adjustment

Shock Pistons

Shock pistons can be replaced with optional pistons to vary the amount of damping. Optional pistons with larger or smaller bypass holes (1, 2, or 3) than the factory-installed shock pistons can be used to decrease or increase damping, respectively. Change pistons if you only have one weight of shock absorber oil available. At the factory, the E-Revo is equipped with #2 pistons in the front and rear.

Shock Disassembly

Shock absorbers must be removed from the vehicle and disassembled to change pistons. Use the exploded view diagrams of the shock absorber included with the model to assist with the assembly process.

1. Remove the spring retainer and the lower spring retainer from the shock absorber.
2. Remove the upper cap (A) and drain all shock absorber oil from the shock absorber body.
3. Remove the lower cap (B) and the square-section seal from the shock absorber body.
4. Use pliers to hold the shock absorber shaft just above the ball end (C). Remove the ball end from the shock absorber shaft using the suspension multi-tool (C).
5. Remove the shock absorber shaft with piston from the shock absorber body through the top of the shock absorber body.

Shock Assembly

1. Replace the shock piston with the optional piston of your choice. Be careful not to loosen the small washer located beneath the piston.
2. Place the new piston onto the shock absorber shaft above the small washer. Hold the shaft threads with pliers or needle-nose pliers and adjust the nut with the cross wrench to secure the assembly.
3. Insert the shock absorber shaft assembly through the shock absorber body until the piston touches the bottom.
4. Lubricate the shaft and square-section seal with silicone oil.
5. Install the square-section seal onto the shaft and toward the inner diameter of the shock absorber body.
6. Install the lower cap using the suspension multi-tool (B).
7. Slide the retainer onto the shaft.
8. Hold the shaft near the threads with needle-nose pliers or pliers and thread the ball end onto the shock absorber shaft until the ball end touches bottom (C).
9. Fill the shock absorber with new silicone shock absorber oil to the top of the shock absorber body. Slowly move the piston up and down (keeping it submerged in oil) to release trapped air. Wait a few minutes for the shock absorber to settle to allow all trapped air to surface.
10. Slowly thread the upper cap with the air chamber of the shock absorber installed onto the shock absorber body with the suspension multi-tool (A). Excess oil will flow through the small hole in the shock absorber cap. Adjust the shock absorber cap until it is snug. Use the included steel shock wrench to hold the shock absorber body while adjusting.
11. Reinstall the spring and lower retainer.

Sealed Gear Differential Precision Adjustments

The front and rear gear differentials allow the left and right wheels to turn at different speeds when cornering so that the tires do not scrub or chatter. This decreases the turning radius and increases steering performance. Differential performance can be adjusted for different driving conditions and performance requirements. The differentials contain silicone differential fluid and are sealed to maintain consistent long-term performance. Changing the differential fluid to a higher or lower viscosity will vary the

Advanced Precision Adjustments

Differential Performance Characteristics

Changing to a higher viscosity oil in the differentials will reduce the tendency for motor power to transfer to the wheel with the least traction. You may notice this when making sharp turns on slippery surfaces. The unloaded wheels on the inside of the turn tend to spin at extremely high RPMs. A higher viscosity (thicker) oil will cause the differentials to act like a spool, distributing equal power to the left and right wheels. The E-Revo will generally benefit from higher viscosity oil when climbing, rock crawling, or running on low-traction surfaces. Note: A heavier oil will allow power to transfer even if one or more tires are not touching the ground. This may increase the possibility of the vehicle flipping.

At the factory, both differentials are filled with SAE 50,000W silicone oil. Use only silicone oil in the differentials. Traxxas sells SAE 10,000W and SAE 30,000 viscosity oil (consult your parts list). Differentials must be removed from the vehicle and disassembled to change or replace the oil.

Motor Installation

To access the motor, remove the gear cover by removing the single screw on the top of the gear cover. The motor uses an aluminum mount for quick and easy motor access and gear adjustment. To remove the motor, remove the large hex screw with the 3 mm wrench. Then, rotate the motor and mount toward the side of the model, and slide it back from the mount.

The motor mount was carefully designed to provide other features and adaptability. Two sets of holes have been provided for use with aftermarket motors. These use 3 mm screws with a 25 mm spacing that is compatible with most aftermarket motors.

These are:

1. Low Center of Gravity Installation: (Standard motor position; the motor is mounted low in the chassis for better handling performance).
2. High Center of Gravity Installation: (The motor is mounted higher to allow more space for larger motors or aftermarket heat sinks).

An additional set of motor mounting holes is included for custom applications. This is for larger aftermarket motors with 4 mm screws and 29 mm to 30 mm spacing.

[Diagram: Center of Gravity Installation Options]

Use differential oil of higher viscosity (thicker) for:

• Achieving more drive to the wheels with the greatest amount of traction.
• Running on smooth surfaces with low traction.
• Achieving better performance on uphill climbs over uneven terrain.

Use differential oil of lower viscosity (thinner) for:

• Achieving more drive to the wheels with the least amount of traction.
• Running on uneven surfaces with low traction.

Resetting to Factory Defaults

When programming your TQi transmitter, you may feel the need to start fresh. Follow these simple steps to reset the factory settings:

1. Turn off the transmitter.
2. Press and hold MENU and SETUP.
3. Turn on the transmitter.
4. Release MENU and SETUP. The transmitter's LED will flash red.
5. Press MENU 6 times. The transmitter's LED will flash red 7 times.
6. Press SETUP to erase the settings. The LED will light green, and the transmitter will reset to factory defaults.

Guide to Advanced TQi Tuning

Your Traxxas transmitter features a multi-function knob that can be programmed to control various advanced transmitter functions (default set to Cruise Control, see page 17). To access the programming menu, use the menu and setup buttons on the transmitter, and observe the LED signals. On page 39, you will find an explanation of the menu structure. Experiment with the settings and functions to see if they can improve your driving experience.

Steering Sensitivity (Exponential)

The multi-function knob on the TQi transmitter can be programmed to control steering sensitivity (also called exponential). The default setting for steering sensitivity is "normal (zero exponential)," with the knob turned fully counter-clockwise within its range of travel. This setting provides linear servo response: steering servo travel exactly matches the input from the transmitter's steering wheel. Turning the knob clockwise from the left will change it to a "negative exponential" setting, and steering sensitivity will decrease. This will reduce servo responsiveness near the neutral position and increase sensitivity as the servo reaches the limits of its travel range. The further you turn the knob, the greater the change in steering servo travel. The term "exponential" comes from this effect; servo travel changes exponentially in proportion to input from the steering wheel. The exponential effect is indicated as a percentage; the higher the percentage, the greater the effect. The following illustrations show how this works.

Normal Steering Sensitivity (0% Exponential Effect): In this illustration, the steering servo travel (and with it, the front wheel steering movement of the model) exactly matches the steering wheel. The ranges have been exaggerated for illustrative purposes.

Reduced Steering Sensitivity (Negative Exponential): Turning the multi-function knob clockwise reduces the model's steering sensitivity. Notice that the relatively large travel of the steering wheel results in shorter servo travel. The further you turn the knob, the greater the effect. Reduced steering sensitivity can be useful when operating the model on low-traction surfaces, when driving at high speeds, or on tracks that favor wide turns where smooth steering movements are required. The ranges have been exaggerated for illustrative purposes.

Throttle Sensitivity (Exponential)

The multi-function knob can be programmed to control throttle sensitivity. Throttle sensitivity works the same way as steering sensitivity, but it applies the effect to the throttle channel. Only forward throttle is affected; brake/reverse travel remains linear regardless of throttle sensitivity setting.

Steering Percentage (Dual-Rate)

The multi-function knob can be programmed to control the amount (percentage) of servo travel applied to steering. Turning the multi-function knob fully clockwise provides maximum steering travel. Turning the knob counter-clockwise reduces steering travel (Note: Turning the dial counter-clockwise to the end will eliminate all servo travel). Keep in mind that the steering end-point settings define the maximum steering travel of the servo. If you set the steering percentage to 100% (by turning the multi-function knob fully clockwise), the servo will travel all the way to its end-point, but not beyond it. Many racers set Dual-Rate to have as much steering travel as they need in the tightest turn on the track, making the model easier to drive through the rest of the race. Reducing steering travel can also be useful, as it makes the model easier to control on high-traction surfaces and limits steering output for oval track racing where large amounts of steering travel are not required.

Brake Percentage

The multi-function knob can also be programmed to control the amount of brake travel applied by the servo on a nitro model. Electric models do not have servo-operated brakes, but the Brake Percentage function works the same way on electric models. Turning the multi-function knob fully clockwise provides maximum brake travel. Turning the knob counter-clockwise reduces brake travel (Note: Turning the dial counter-clockwise to the end will eliminate all brake action).

Throttle Trim

Programming the multi-function knob to serve as throttle trim allows you to adjust the throttle neutral position to prevent unwanted drag or throttle application when the transmitter trigger is at neutral. Note: Your transmitter is equipped with a throttle trim search mode to prevent accidental uncontrolled operation. Refer to the side column for more information.
