Safety Is Your Responsibility!

Important Points to Remember

• Because your model is controlled by radio, it is subject to radio interference from many sources that are beyond your control. Since radio interference can cause momentary losses of radio control, always allow a safety margin in all directions around the model to prevent collisions.
• Range test your radio system in the area that you will be running the model to ensure that you have a range that covers the area you want to drive. After range testing, drive slowly in the area at first to make sure there is no interference that can cause momentary lapses of control.
• Always use new batteries in your model to maximize signal power output and range.
• The motors, batteries, and speed control can become hot during use. Be careful to avoid getting burned.
• Choose the right location to drive. Your model is absolutely not intended for use on public roads or congested areas where its operation can conflict with or disrupt pedestrian or vehicular traffic. This is to prevent the possibility of injury or death resulting from a collision with the model by another human being or animal.
• Do not drive the XRT Ultimate by yourself. Bring a friend along to act as a spotter to alert you if a person or animal is approaching.
• Do not operate your model at night, or anytime your line of sight to the model may be obstructed or impaired in any way.
• Do not drive the model close to you where a mistake or loss of control could cause the model to collide with you or any spectator.
• Always carefully inspect your model for damage or loose components before running. Do not drive the model if it is damaged in any way. Tighten any loose hardware. Tighten the wheel nuts before each running session and periodically check the tightness of the wheel nuts while you are running.
• Never pick up the model by its tires or wheels. Always keep your hands safely clear of moving parts whenever the batteries are plugged in.
• Keep the XRT Ultimate stored with the batteries removed, out of the reach of children and protected from access by any other unauthorized driver.
• Always disconnect the batteries in the model when it is not in use. Never store the vehicle with batteries in the model, as this can cause a fire leading to property damage, serious personal injury, or even death.
• Do not continue to operate the model with a low battery, 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.
• Most importantly, use good common sense at all times.

Speed Control

Your model’s electronic speed control (ESC) is an extremely powerful electronic device capable of delivering high current. Please closely follow these precautions to prevent damage to the speed control or other components.

• Disconnect the Battery: Always disconnect the batteries from the speed control when not in use.
• Insulate the Wires: Always insulate exposed wiring with heat shrink tubing to prevent short circuits.
• Transmitter on First: Switch on your transmitter fi, then switch on the speed control to prevent runaways and erratic performance.
• Don’t Get Burned: The ESC and motor can become extremely hot during use, so be careful not to touch them until they cool. Supply adequate airflow for cooling.
• Use Traxxas High-Current Connectors: Do not change the battery and motor connectors. Improper wiring can cause fire or damage to the ESC. Please note that modified speed controls can be subject to a rewiring fee when returned for service.
• No Reverse Voltage: The ESC is not protected against reverse polarity voltage.
• No Schottky Diodes: External Schottky diodes are not compatible with reversing speed controls. Using a Schottky diode with your speed control will damage the ESC and void the warranty.
• Always adhere to the minimum and maximum limitations of the speed control as stated in the specifications table in the Owner’s Manual. If your ESC operates on two batteries, 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.

TRAXXAS TQi RADIO & VELINEON POWER SYSTEM

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 complement 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 of functions. The detailed instructions (page 30) and Menu Tree (page 33) 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 30.

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 motosynchronize with each other. The VXL-8s electronic speed control is optimized to virtually eliminate cogging.

Current

Current is a measure of power flow through the electronics, usually measured in amps. If you think of a wire as a garden hose, current is a measure of how much water is flowing through the hose.

ESC (Electronic Speed Control)

An electronic speed control is the electronic motor control inside the model. The VXL-8s electronic speed control uses advanced circuitry to provide precise, digital proportional throttle control. Electronic speed controls use power more efficiently than mechanical speed controls, so that the batteries run longer. An electronic speed control also has circuitry that prevents loss of steering and throttle control as the batteries lose their charge.

Frequency band

The radio frequency used by the transmitter to send signals to your model. This model operates on the 2.4GHz direct-sequence spread spectrum.

kV Rating

Brushless motors are often rated by their kV number. The kV rating equals the no-load motor rpm with 1 volt applied. The kV increases as the number of wire turns in the motor decreases. As the kV increases, the current draw through the electronics also increases. The Velineon 1200XL motor is a 1200 kV motor.

LiPo

Abbreviation for Lithium Polymer. Rechargeable LiPo battery packs are known for their special chemistry, which allows extremely high energy density and current handling in a compact size. These are high-performance batteries that require special care and handling. LiPo battery packs are for advanced users only.

mAh

Abbreviation for milliamp hour, a measure of the capacity of the battery pack. The higher the number, the longer the battery will last between recharges.

Neutral position

The standing position that the servos seek when the transmitter controls are at the neutral setting.

NiCad

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

NiMH

Abbreviation for nickel-metal hydride. Rechargeable NiMH batteries offer high current handling and much greater resistance to the “memory” effect. NiMH batteries generally allow higher capacity than NiCad batteries. They can last up to 500 charge cycles. A peak charger designed for NiMH batteries is required for optimal performance.

Receiver

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

Resistance

In an electrical sense, resistance is a measure of how an object resists or obstructs the flow of current through it. When flow is constricted, energy is converted to heat and is lost. The Velineon power system is optimized to reduce electrical resistance and the resulting power-robbing heat.

Rotor

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

Sensored

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

Sensorless

Sensorless refers to a brushless motor that uses advanced instructions from an electronic speed controller to provide smooth operation. Additional motor sensors and wiring are not required. The VXL-8s electronic speed control is optimized for smooth sensorless control.

Servo

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

Transmitter

The hand-held radio unit that sends throttle and steering instructions to your model.

Trim

The fine-tuning adjustment of the neutral position of the servos, made by adjusting the throttle and steering trim knobs on the face of the transmitter. Note: The Multi-Function knob must be programmed to serve as a throttle trim adjustment.

Thermal Shutdown Protection

Temperature-sensing electronics used in the VXL-8s 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 consists 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.

Your model is equipped with the newest TQi 2.4GHz transmitter with Traxxas Link™ Model Memory. The transmitter has two channels for controlling your throttle and steering. The receiver inside the model has 5 output channels. Your model is equipped with one servo and an electronic speed controller.

TRANSMITTER AND RECEIVER

1. Remove the battery compartment door by pressing the tab and sliding the door open.
2. Install the batteries in the correct orientation, as indicated in the battery compartment.
3. Reinstall the battery compartment door and snap it closed.
4. Turn on the transmitter and check the status LED for a solid green light.

If the status LED flashes red, the transmitter batteries may be weak, discharged, or possibly installed incorrectly. Replace with new batteries. The status LED does not indicate the charge level of the battery pack installed in the model. Refer to the troubleshooting section on page 31 for more information on the transmitter status LED codes.

SELECTING BATTERIES FOR YOUR MODEL

Your model does not include batteries or a charger. Two identical Lithium Polymer (LiPo) batteries equipped with Traxxas iD® High-Current Connectors are required. Do not use Nickel Metal Hydride (NiMH) batteries. Traxxas Power Cell iD batteries are strongly recommended for maximum performance and safer charging. The following chart lists the available Power Cell batteries for your model:

• 2890X 6700mAh 14.8v 4-Cell (4s) 25C LiPo iD Battery

*Requires additional battery pack spacers for proper fitment (part #7819, sold separately).

Note: When operating the XRT Ultimate with 4s LiPo batteries and stock gearing, the top speed is 50+mph. 2s/3s LiPo performance will be much slower.

WARNING: FIRE HAZARD!

Users of Lithium Polymer (LiPo) batteries must read the Warnings and Precautions beginning on page 4. You MUST use a LiPo balance charger for LiPo batteries, or battery damage with the potential for fire will result.

DO NOT use NiMH batteries with the VXL-8s electronic speed control. The batteries will become extremely hot, and damage or injury could occur.

SELECTING A CHARGER FOR YOUR MODEL

Make certain you choose the correct type of charger for the batteries you select. Traxxas recommends you choose a genuine Traxxas EZ-Peak iD charger for safer charging and maximum battery life and performance.

REMOVING AND INSTALLING THE BODY

Your XRT Ultimate includes an innovative latching system (patent pending) for securing the body to the chassis (body clips are not required).

To remove the body for chassis access:

1. Reach beneath the front and rear body fenders and pull the latches toward the outside of the truck body to release them.
2. Push up on the latches to fully disengage them from the body mounts.
3. Lift the body straight up from the chassis. Lift the front and rear of the body evenly, or it may become difficult to remove.

To reinstall the body

1. Position the body on the chassis. Align the front and rear of the body with the bumpers.
2. Press down on the body at each latch location until the latches snap into place.

Note: To keep the clipless system functioning properly, periodically inspect and clean the latches on the body and the slots on the body mounts. If dirt and grime accumulate on these components, the clipless system will not operate smoothly..

INSTALLING THE BATTERY PACKS

1. Push the battery hold-down toward the center of the truck using the two release tabs, and lift the hold-down up and toward you.
2. Insert a fully charged battery into the battery compartment with the High Current Connector positioned toward the rear of the model.
3. Lower the battery hold-down and pull it toward the outside of the truck to snap it closed.
4. Repeat for the opposite battery.

Note: The battery compartment will accommodate the Traxxas 6700mAh 4s battery pack (part #2890X). When using other LiPo batteries, additional foam blocks and battery pack spacers are required for proper fitment (see battery chart).

The Traxxas High-Current Connector

Your model is equipped with the Traxxas High-Current Connector. Standard connectors restrict current flow and are not capable of delivering the power needed to maximize the output of the VXL-8s. The Traxxas connector’s gold-plated terminals, with large contact surfaces, ensure positive current flow with the least amount of resistance. Secure, long-lasting, and easy to grip, the Traxxas connector is engineered to extract all the power your battery has to give.

RADIO SYSTEM CONTROLS

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, nd running out of control. Your model has electronic fail-safes 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. Either the transmitter or receiver LED flashing red indicates a failure to link. If you miss it, simply turn off the transmitter and start over.
• Always turn on the transmitter before plugging in the battery.

RADIO SYSTEM BASIC ADJUSTMENTS

Steering Trim

The 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 17 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 details on TSM, refer to page 17.

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 pack in the model into the speed control.
4. The on/off switch is integrated into the speed control. With the transmitter on, press and release the EZ-Set button (.25 seconds). The LED will shine GREEN. This turns the model on. To turn the VXL-8s off, unplug the batteries.
5. Turn the steering wheel on the transmitter back and forth and check for rapid operation of the steering servo. Also, check that the steering mechanism is not loose or binding. If the steering operates slowly, check for weak batteries.
6. When looking down at the model, the front wheels should be pointing straight ahead. If the wheels are turned slightly to the left or right, turn off TSM (see page 17) and slowly adjust the steering trim control on the transmitter until they are pointing straight ahead; then, return the multi-function knob to the desired TSM setting.
7. Gently operate the throttle trigger to ensure that you have forward and reverse operation, and that the motor stops when the throttle trigger is at neutral. Warning: Do not apply full throttle in forward or reverse while the model is elevated.
8. Once adjustments are made, turn off the receiver on your model, followed by the hand-held transmitter.

Range-Testing the Radio System

Before each running session with your model, you should range-test your radio system to ensure that it operates properly.

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

Higher Speeds Require Greater Distance

The faster you drive your model, the more quickly it will near the limit of radio range. At 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.

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 are also made possible as TSM makes corrections for you, without intruding on your fu, 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 by the factory. The antenna is secured by a 3x4mm set screw. To remove the antenna tube, simply remove the set screw with the included 1.5mm wrench.

When reinstalling the antenna, first slide the antenna wire into the bottom of the antenna tube until the white tip of the antenna is at the top of the tube under the black cap. Next, insert the antenna tube into the mount while making sure that the antenna wire is in the slot in the antenna mount; then, install the set screw next to the antenna tube. Use the supplied 1.5mm wrench to tighten the screw just until the antenna tube is securely in place. Do not overtighten. Do not bend or kink the antenna wire (see the sidebar for more information). Do not shorten the antenna tube.
