TRAXXAS TQi RADIO & VELINEON POWER SYSTEM

INTRODUCTION
Your model includes the latest Traxxas TQi 2.4GHz transmitter with Traxxas LinkTM 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 DualRate 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 33) and Menu Tree (page 37) 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 33.
2.4GHz Spread Spectrum ­ This model is equipped with the latest R/C technology. Unlike AM and FM systems that require frequency crystals and are prone to frequency conflicts, the TQi system automatically selects and locks onto an open frequency and offers superior resistance to interference and “glitching.”
BEC (Battery Eliminator Circuit) – The BEC can either be in the receiver or in the ESC. This circuit allows the receiver and servos to be powered by the main battery pack in an electric model. This eliminates the need to carry a separate pack of 4 AA batteries to power the radio equipment.
Brushless Motor – A D/C brushless motor replaces the brushed motor’s traditional commutator and brush arrangement with intelligent electronics that energize the electromagnetic windings in sequence to provide rotation. Opposite of a brushed motor, the brushless motor has its windings (coils) on the perimeter of the motor can and the magnets are mounted to the spinning rotor shaft.
Cogging – Cogging is a condition sometimes associated with brushless motors. Typically, it is a slight stutter noticed when accelerating from a stop. It happens for a very short period as the signals from the electronic speed control and the motor synch with each other. The VXL-3s 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-3s electronic speed control uses advanced circuitry to provide precise, digital proportional throttle control. Electronic speed controls use power more efficiently than mechanical speed controls so that the batteries run longer. An electronic speed control also has circuitry that prevents loss of steering and throttle control as the batteries lose their charge.
Frequency band – The radio frequency used by the transmitter to send signals to your model. This model operates on the 2.4GHz direct-sequence spread spectrum.
kV Rating – Brushless motors are often rated by their kV number. The kV rating equals no-load motor rpm with 1 volt applied. The kV increases as the number of wire turns in the motor decreases. As the kV increases, the current draw through the electronics also increases. The Velineon 3500 motor is a 3500 kV motor optimized for the best speed and efficiency in lightweight 1/10 scale models.
LiPo – Abbreviation for Lithium Polymer. Rechargeable LiPo battery packs are known for their special chemistry, which allows extremely high energy density and current handling in a compact size. These are high performance batteries that require special care and handling. LiPo battery packs are for advanced users only.
mAh ­ Abbreviation for milliamp hour, a measure of the capacity of the battery pack. The higher the number, the longer the battery will last between recharges.
Neutral position – The standing position that the servos seek when the transmitter controls are at the neutral setting.
NiCad – Abbreviation for nickel-cadmium. The original rechargeable hobby pack, NiCad batteries have very high current handling, high capacity, and can last up to 1000 charging cycles. Good charging procedures are required to reduce the possibility of developing a “memory” effect and shortened run times.

TRAXXAS TQi RADIO & VELINEON POWER SYSTEM

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. The VXL-3s electronic speed control is able to use sensored motors when applications benefit from them (such as some sanctioned racing classes).
Sensorless – Sensorless refers to a brushless motor that uses advanced instructions from an electronic speed control to provide smooth operation. Additional motor sensors and wiring are not required. The VXL-3s electronic speed control is optimized for smooth sensorless control.
Servo – Small motor unit in your model that operates the steering mechanism.
Solder Tabs – Accessible, external contacts on the motor that allows for easy wire replacement. The Velineon 3500 is equipped with solder tabs.
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- 3s electronic speed control detect overloading and overheating of the transistor circuitry. If excessive temperature is detected, the unit automatically shuts down to prevent damage to the electronics.
2-channel radio system – The TQi radio system, consisting of the receiver, the transmitter, and the servos. The system uses two channels: one to operate the throttle and one to operate the steering.
Voltage – Voltage is a measure of the electrical potential difference between two points, such as between the positive battery terminal and ground. Using the analogy of the garden hose, while current is the quantity of water flow in the hose, voltage corresponds to the pressure that is forcing the water through the hose.
IMPORTANT RADIO SYSTEM PRECAUTIONS
· Do not kink the receiver’s antenna wire. Kinks in the antenna wire will reduce range.
· DO NOT CUT any part of the receiver’s antenna wire. Cutting the antenna will reduce range.
· Extend the antenna wire in the model as far as possible for maximum range. It is not necessary to extend the antenna wire out of the body, but wrapping or coiling the antenna wire should be avoided.
· Do not allow the antenna wire to extend outside the body without the protection of an antenna tube, or the antenna wire may get cut or damaged, reducing range. It is recommended to keep the wire inside the body (in the antenna tube) to prevent the chance of damage.

To prevent loss of radio range do not kink or cut the black wire, do not bend or cut the metal tip, and do not bend or cut the white wire at the end of the metal tip.

RADIO SYSTEM RULES
· Always turn your TQi transmitter on first and off last. This procedure will help to prevent your model from receiving stray signals from another transmitter, or other source, and running out of control. Your model has electronic 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 turn your transmitter on first.

Plug in the battery.

Turn on the model.

TRAXXAS TQi RADIO & VELINEON POWER SYSTEM

· Always use new batteries for the radio system. Weak batteries will limit the radio signal between the receiver and the transmitter. Loss of the radio signal can cause you to lose control of your model.
· In order for the transmitter and receiver to bind to one another, the receiver in the model must be turned on within 20 seconds of turning on the transmitter. The transmitter LED will flash fast red, indicating a failure to link. If you miss it, simply turn off the transmitter and start over.
· Always turn on the transmitter before plugging in the battery.
RADIO SYSTEM BASIC ADJUSTMENTS
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 16 for TSM adjustments.
Multi-Function Knob The Multi-Function knob can be programmed to control a variety of functions. From the factory, the MultiFunction knob controls Traxxas Stability Management (TSM). For more detail on TSM, refer to page 16.
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 RED (see note below). This turns the model on. To turn the VXL-3s off, press and hold the EZ-Set button until the LED turns off (.5 seconds).

Note: If the LED shines green, Low-Voltage Detection is activated. This will cause erratic performance from NiMH battery packs. The default factory setting is for Low-Voltage Detection to be disabled (LED shines red). Make sure to turn the low voltage detection on when using LiPo batteries. Never use LiPo batteries while Low-Voltage Detection is turned off. See page 18 for more information.
5. Turn the steering wheel on the transmitter back and forth and check for rapid operation of the steering servo. Also, check that the steering mechanism is not loose or binding. If the steering operates slowly, check for weak batteries.
6. When looking down at the model, the front wheels should be pointing straight ahead. If the wheels are turned slightly to the left or right, turn off TSM (see page 16) 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 rangetest 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.

Remember, always turn the TQi transmitter on first and off last to avoid damage to your model.
Automatic Fail-Safe The TQi transmitter and receiver are equipped with an automatic fail-safe system that does not require user programming. In the event of signal loss or interference, the throttle will return to neutral and the steering will hold its last commanded position. If the fail-safe system activates while you are operating your model, determine the reason for signal loss and resolve the problem before operating your model again.
Stop immediately at the first sign of weak batteries. Never turn the transmitter off when the battery pack is plugged in. The model could run out of control.

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 another 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 is also made possible as TSM makes corrections for you, without intruding on your fun, or creating unexpected side effects.

The Multi-Function knob on the TQi transmitter has been programmed to control TSM. The recommended (default) setting for TSM is to rotate the knob to the 12:00 position (the zero mark on the dial).

Recommended setting

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.

Decrease assistance
TSM off

Increase assistance

When driving on surfaces with some traction, decrease the TSM setting to allow the vehicle to feel more “loose” for power sliding, drifting, and so on. On surfaces with very little traction (loose dirt, smooth concrete, ice/snow), increase TSM to maximize acceleration and control.

Drive with TSM on and off to test how it is making your control of the vehicle easier and more precise. For more information, visit Traxxas.com/tsm.

Note: TSM must be completely turned off while adjusting steering trim.

SETTING UP THE ANTENNA

The receiver antenna has been set up

and installed from the factory. The

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

Antenna Mount

Use the supplied 1.5mm wrench

to tighten the screw just until the

antenna tube is securely in place. Do not over tighten. Do not bend

or kink the antenna wire! See the sidebar for more information.

Do not shorten the antenna tube.

SELF RIGHTING
Your model is equipped with Traxxas Self Righting that will allow you to automatically return it to an upright position after a rollover.* Make sure there is adequate space around your Rustler 4X4 Ultimate and no people or animals are nearby before self righting. The model moves quickly and the tires are spinning at high speed. If a person or animal approaches the model during self righting, cancel immediately by moving the steering wheel or the throttle trigger. Press and hold the SET button on the transmitter for four (4) seconds to activate the self-righting feature. Once activated, the SET button can be released. Note: Certain driving surfaces or conditions may prevent the model from uprighting itself. After several attempts, self righting will cancel. Press the SET button to try again, or go and retrieve your model.

LED Codes and Protection Modes
· Solid Green: VXL-3s power-on light. Low-Voltage Detection is ACTIVATED (LiPo setting).
· Solid Red: VXL-3s power-on light. Low-Voltage Detection is DISABLED (NiCad/NiMH setting). Never use LiPo batteries while Low-Voltage Detection is disabled.
· Slow Blinking Red (with Low-Voltage Detection on): The VXL-3s has entered Low-Voltage Protection. When the battery voltage begins to reach the minimum recommended discharge voltage threshold for LiPo battery packs, the VXL-3s will limit the power output to 50% throttle. When the battery voltage attempts to fall below the minimum threshold, the VXL-3s will shut down all motor output. The LED on the speed control will slowly blink red, indicating a low- voltage shutdown. The VXL-3s will stay in this mode until a fully charged battery is connected.

· Fast Blinking Red: Thermal Shutdown Protection Stage 1. If the motor has lower than normal power and the VXL-3s is hot, the VXL-3s has entered Stage 1 Thermal Shutdown Protection to guard against overheating caused by excessive current flow. If the motor has no power and the VXL-3s is very hot, the VXL-3s has entered Stage 2 Thermal Shutdown Protection and has automatically shut down. Let the VXL3s cool. Make sure your model is properly geared for the conditions (see page 27).
· Very Fast Blinking Red: Thermal Shutdown Protection and Low Voltage Protection (see above) have occurred at the same time.
· Alternating; Blinks Red then Green: If the motor has no power, the VXL-3s has entered Over Voltage Protection. If a battery with too high voltage is used, the VXL-3s will go into a fail-safe mode. WARNING: If input voltage exceeds approximately 20-volts, the ESC may be damaged. Do not exceed 12.6 maximum peak input voltage.
· Blinking Green: The VXL-3s is indicating the transmitter Throttle Trim (see page 34) is incorrectly set. If the MultiFunction knob is set to throttle trim, then adjust the Throttle Trim to the middle “0” setting.

DRIVING YOUR MODEL

Now it’s time to have some fun! This section contains instructions on driving and making adjustments to your model. Before you go on, here are some important precautions to keep in mind.
· Allow the model to cool for a few minutes between runs. This is particularly important when using high-capacity battery packs that allow extended periods of running. Monitoring temperatures will extend the lives of the batteries and motors. See page 28 for advanced user information on monitoring temperatures.
· Do not continue to operate the model with low batteries or you could lose control of it. Indications of low battery power include slow operation, sluggish servos (slow to return to center), or ESC shutdown due to the Low- Voltage Detection circuitry. Stop immediately at the first sign of weak batteries. When the batteries in the transmitter become weak, the power light will begin to flash red. Stop immediately and install new batteries.
· Do not drive the model at night, on public streets, or in large crowds of people.
· If the model becomes stuck against an object, do not continue to run the motor. Remove the obstruction before continuing. Do not push or pull objects with the model.
· Because the model is controlled by radio, it is subject to radio interference from many sources beyond your control. Since radio interference can cause momentary losses of control, allow a safety margin of space in all directions around the model in order to prevent collisions.
· Use good, common sense whenever you are driving your model. Intentionally driving in an abusive and rough manner will only result in poor performance and broken parts. Take care of your model so that you can enjoy it for a long time to come.
· When using the supplied optional pinion for top-speed running, limit your driving to paved surfaces only. Running in grass and off-road could cause excessive loads on the electrical system in the model.
· High-performance vehicles produce small vibrations that may loosen hardware over time. Frequently check wheel nuts and other screws on your vehicle to ensure that all hardware remains properly tightened.
About Run Time A large factor affecting run time is the type and condition of your batteries. The milliamp hour (mAh) rating of the batteries determines how large their “fuel tank” is. A 3000mAh battery pack will theoretically run twice as long as a 1500mAh sport pack. Because of the wide variation in the types of batteries that are available and the methods with which they can be charged, it’s impossible to give exact run times for the model.

Another major factor that affects run time is how the model is driven. Run times may decrease when the model is driven repetitively from a stop to top speed and with repetitive hard acceleration.
Tips for Increasing Run Time · Use batteries with the highest mAh rating you can purchase.
· Use a high-quality peak-detecting charger.
· Read and follow all maintenance and care instructions provided by the manufacturer of your batteries and charger.
· Keep the VXL-3s cool. Get plenty of airflow across the ESC heat sinks.
· Use the correct Low-Voltage Detection setting for your battery (see page 18). Low-Voltage Detection can be off for maximum NiMH battery runtime. Never use LiPo batteries while Low-Voltage Detection is turned off.
· Lower your gear ratio. Installing a smaller pinion or larger spur gear will lower your gear ratio, causing less power draw from the motor and battery, and reducing overall operating temperatures.
· Maintain your model. Do not allow dirt or damaged parts to cause binding in the drivetrain. Keep the motor clean.
mAh Ratings and Power Output The mAh rating of the battery can affect your top-speed performance. The higher capacity battery packs experience less voltage drop under heavy load than low mAh rated packs. The higher voltage potential allows increased speed until the battery begins to become discharged.
RUNNING IN WET CONDITIONS
Your new Traxxas model is designed with water-resistant features to protect the electronics in the model (receiver, servos, electronic speed control). This gives you the freedom to have fun driving your model through puddles, wet grass, snow, and through other wet conditions. Though highly water resistant, the model should not be treated as though it is submersible or totally 100% waterproof. Water resistance applies only to the installed electronic components. Running in wet conditions requires additional care and maintenance for the mechanical and electrical components to prevent corrosion of metal parts and maintain their proper function.
Precautions · Without proper care, some parts of your model can be seriously
damaged due to contact with water. Know that additional maintenance procedures will be required after running in wet conditions in order to maintain the performance of your model. Do not run your model in wet conditions if you are not willing to accept the additional care and maintenance responsibilities.

DRIVING YOUR MODEL

· Not all batteries can be used in wet environments. Consult your battery manufacturer to see if their batteries can be used in wet conditions. Do not use LiPo batteries in wet conditions.
· The Traxxas TQi transmitter is not water resistant. Do not subject it to wet conditions such as rain.
· Do not operate your model during a rain storm or other inclement weather where lightning may be present.
· Do not allow your model to come in contact with salt water (ocean water), brackish water (between fresh water and ocean water), or other contaminated water. Salt water is highly conductive and highly corrosive. Use caution if you plan to run your model on or near a beach.
Before Running Your Vehicle in Wet Conditions 1. Consult the section “After Running Your Vehicle in Wet Conditions”
before proceeding. Make sure you understand the additional maintenance required with wet running.
2. The wheels have small holes molded in to allow air to enter and exit the tire during normal running. Water will enter these holes and get trapped inside the tires if holes are not cut in the tires. Cut two small holes (3mm or 1/8″ diameter) in each tire. Each hole should be near the tire center-line, 180 degrees apart.
3. Confirm that the receiver box O-ring and cover are installed correctly and secure. Make sure the screws are tight and the blue O-ring is not visibly protruding from the edge of the cover.
4. Confirm that your batteries can be used in wet conditions.
5. Use lower gearing (smaller pinion gears, as low as 9T or spur gear as large as 54T) when running in mud, deep puddles, snow, or other similar situations that will restrict the tires and put much higher loads on the motor.
Motor Precautions · Velineon motor life can be greatly reduced in mud and water. If the
motor gets excessively wet or submerged, use very light throttle (run the motor slowly) until the excess water can run out. Applying full throttle to a motor full of water can cause rapid motor failure. Your driving habits will determine motor life with a wet motor. Do not submerge the motor under water.
· Do not gear the motor by temperature when running in wet conditions. The motor will be cooled by water contact and will not give an accurate indication of appropriate gearing.

· Use special care when operating your model in muddy conditions. Stop operating your model if it appears to be straining due to the tackiness of the mud or build-up of mud on the chassis. Do not allow mud to collect on the motor or pack around the motor.
After Running Your Vehicle in Wet Conditions 1. Drain the tires by spinning the tires at high speed to “sling” the water
out. One way to do this is to make several high-speed passes on a flat, dry surface (if possible).
2. Remove the batteries.
3. Rinse excess dirt and mud off the truck with low-pressure water, such as from a garden hose. Do not use a pressure washer or other highpressure water. Avoid directing water into the bearings, differentials, etc.
4. Blow off the truck with compressed air (optional, but recommended). Wear safety glasses when using compressed air.
5. Remove the wheels from the truck.
6. Spray all the bearings, drivetrain, and fasteners with WD-40® or similar water-displacing light oil.
7. Let the truck stand or you may blow it off with compressed air. Placing the truck in a warm, sunny spot will aid drying. Trapped water and oil will continue to drip from the truck for a few hours. Place it on a towel or piece of cardboard to protect the surface underneath.
8. As a precautionary step, remove the sealed receiver box cover. While unlikely, humidity or tiny amounts of moisture or condensation may enter the receiver box during wet running. This can cause long-term problems with the sensitive electronics in the receiver. Removing the receiver box cover during storage allows the air inside to dry. This step can improve the long-term reliability of the receiver. It is not necessary to remove the receiver or unplug any of the wires.
9. Additional Maintenance: Increase your frequency of disassembly, inspection, and lubrication of the following items. This is necessary after extended wet use or if the vehicle will not be used for an extended period of time (such as a week or longer). This additional maintenance is needed to prevent any trapped moisture from corroding internal steel components.
· Stub axle housing bearings: Remove, clean, and re-oil the bearings.
· Differentials: Remove, disassemble, clean, and re-grease the differential components. Use a light coating of wheel bearing grease (from an auto parts store) on the metal gear teeth. Refer to your exploded view diagrams for help with disassembly and reassembly.

22 · RUSTLER 4X4 ULTIMATE

DRIVING YOUR MODEL

· Velineon motor: After operating your model in wet or muddy conditions, remove the motor and clean any mud or dirt from the bearings. To access the rear bearing, remove the plastic cap with thumb pressure, or gently pry the cap off with a flat-blade screwdriver. To prevent corrosion and assure maximum bearing life, lubricate the bearings with a light oil (available at your local hobby store). Following these steps will extend motor life and maintain peak performance. Be sure to wear eye protection when using spray aerosol cleaners.
RECEIVER BOX: MAINTAINING A WATERTIGHT SEAL
Removing and Installing Radio Gear The unique design of the receiver box allows the removal and installation of the receiver without losing the ability to maintain a watertight seal in the box. The patent-pending wire clamp feature gives you the ability to also install aftermarket radio systems and maintain the watertight features of the receiver box.
Removing the Receiver 1. Remove the wire clamp by removing the two 2.5x8mm cap screws.
2. Remove the cover by removing the two 3x10mm cap screws.
3. To remove the receiver from the box, simply lift it out and set to the side. The antenna wire is still inside the clamp area and cannot be removed yet.
4. Unplug the servo cables from the receiver and remove the receiver.
Receiver Installation 1. Install the electronic speed control (ESC), servo, A
and antenna wiring through the receiver box top (A).
2. Using double-sided adhesive foam tape, install the receiver into the box. Make sure the box light pipe is aligned with the receiver LED.
Note: For best performance, it is recommended that the receiver be installed in the original orientation as shown.

3. Plug ESC and servo wires into the receiver. Refer B to page 12 for the wiring diagram.

4. Make sure the O-ring is properly seated into the groove in the receiver box bottom so that the cover will not pinch it or damage it in any way.
5. Place receiver box top onto receiver box bottom C and install and tighten the two 3x10mm cap screws securely.

6. Inspect the cover to make sure that the O-ring

seal is not visible.

D

7. Arrange the wires neatly using the wire guides on the receiver box top (B). Excess ESC and servo wiring should be bundled inside the receiver box. Pull out all available antenna wiring from the receiver box.

8. Apply a small bead of silicone grease (Traxxas part #1647) to the foam on the wire clamp (C).

9. Install the wire clamp and tighten the two 2.5x8mm cap screws securely (D).

BASIC TUNING ADJUSTMENTS

All of the toe links are installed on the truck so the left-hand thread indicators point to the same direction. This makes it easier to remember which way to turn the wrench to increase or decrease toe link length (the direction is the same at all four corners). Note that the groove in the hex indicates the side of the toe link with the left-hand threads.
Rear toe-in can be adjusted using accessory rear axle carriers, Traxxas Part

Once you become familiar with driving your model, you might need to make adjustments for better driving performance
ADJUSTING GEAR MESH Incorrect gear mesh is the most common cause of stripped spur gears. Rustler 4X4 Ultimate makes improper gear mesh virtually impossible. A factory installed fixed gear adapter helps set the motor in the proper place according to the pinion and spur gear that are selected. Access the gears by removing the single screw on the top gear cover.

ADJUSTING THE CAMBER The camber angle of both the front and rear wheels can be adjusted with the camber links (upper turnbuckles). Use a square or rightangle triangle to set the camber accurately. Adjust the front wheels to 1° to 2° of negative camber. In the rear, adjust the wheels to 1° to 2° of negative camber. These adjustments should be set with the truck positioned at its normal ride height.

ADJUSTING THE TOE-IN
Geometry and alignment specs play an important role in your model’s handling. Take the time to set them correctly. Turn off TSM (see page 16); then, set the steering trim on your transmitter to neutral. Now, adjust your servo and tie rods so that both wheels are pointing straight ahead and are parallel to each other (0° toe-in). This will ensure the same amount of steering in both directions.

BASIC TUNING ADJUSTMENTS

SHOCK MOUNTING POSITIONS Big bumps and rough terrain require a softer suspension with the maximum possible suspension travel and ride height. Racing on a prepared track or on-road use requires a lower ride height and firmer, more progressive suspension settings. The more progressive suspension settings help reduce body roll (increased roll stiffness), dive during braking, and squat during acceleration.
The suspension of your model has been set up for off-road performance (position 2 on the front suspension arms and position 3 on the rear suspension arms). If you plan on driving on hard surfaces, the following changes should be made:
1. Move the front shocks to position 3 on the suspension arms. 2. Move the rear shocks to position 4 on the suspension arms. 3. Add additional preload spacers. 4. Position 1 is not recommended for front or rear.
Experiment with different springs and shock oils to find what works best for your current track conditions.

CENTERING YOUR SERVO If you have removed the servo horn from your model’s steering servo, or the servo has been removed for service or cleaning, the servo must be re-centered prior to installation of the servo horn or installation of the servo in the model. 1. Remove the servo horn from the steering servo. 2. Connect the steering servo to channel 1 on the receiver. Connect
the electronic speed control (ESC) to channel 2. The white wire on the servo lead is positioned toward the receiver’s LED. 3. Turn the transmitter power switch on. Make certain the transmitter’s batteries are not depleted. 4. Turn off TSM (see page 16). 5. Turn the transmitter’s steering trim knob to the center “0” position. 6. Disconnect motor wires “A” and “C” (see page 12) to prevent the motor from turning during the next steps. Connect a fresh battery pack to the speed control and turn on the ESC (see page 18). The servo’s output shaft will automatically jump to its center position. 7. Install the servo horn onto the servo output shaft. The servo horn should face toward the center of the chassis and be perpendicular to the servo body. 8. Check servo operation by turning the steering wheel back and forth to ensure that the mechanism has been centered properly and you have equal throw in both directions. Use the transmitter’s steering trim knob to fine-tune the position of the servo horn so the model tracks straight when the steering wheel is at neutral.
ADJUSTING THE SLIPPER CLUTCH The model is equipped with an adjustable slipper clutch, which is built into the large spur gear. The purpose of the slipper clutch is to regulate the amount of power sent to the wheels to prevent tire spin. When it slips, the slipper clutch makes a high-pitch, whining noise. To adjust the slipper, remove the slipper gear assembly from your model (see page 26 for instructions), and turn the adjusting nut clockwise to tighten or counterclockwise to loosen. Adjust the slipper so that you can hear it slip for a moment from a standing, full throttle start. (Learn more about adjusting the slipper clutch in the sidebar.)

To achieve a good starting point for the slipper clutch in this model, remove the slipper gear assembly from your model (see page 26 for instructions) and tighten the slipper clutch adjusting nut clockwise until the slipper clutch adjusting spring fully collapses (do not over tighten), and then turn the slipper clutch nut counterclockwise one full turn.
Do not run your model with the slipper clutch adjusting spring fully compressed. The minimum recommended slipper clutch setting is 1/2 turn counterclockwise from fully compressed.

Your model requires timely maintenance in order to stay in top running condition. The following procedures should be taken very seriously.
Frequently inspect the vehicle for obvious damage or wear. Look for: 1. Cracked, bent, or damaged parts 2. Check the wheels and steering for binding. 3. Check the operation of the shock absorbers. 4. Check the wiring for any frayed wires or loose connections. 5. Check the mounting of the receiver and servo(s) and speed control. 6. Check the tightness of the wheel nuts with a wrench. 7. Check the operation of the radio system, especially the condition
of the batteries. 8. Check for any loose screws in the chassis structure or suspension. 9. Check the operation of the steering servo and ensure that it is not binding. 10. Inspect the gears for wear, broken teeth, or debris lodged between
the teeth. 11. Check the tightness of the slipper clutch.
Other periodic maintenance: · Slipper clutch pads (friction material): Under normal use, the friction material in the slipper clutch should wear very slowly. If the thickness of any one of the slipper clutch pads is 1.8mm or less, the friction disc should be replaced. Measure the pad thickness using calipers or measuring against the diameter of the 1.5 and 2.0mm hex wrenches provided with the model.
· Chassis: Keep the chassis clean of accumulated dirt and grime. Periodically inspect the chassis for damage.

it is time to replace the part. Remove the gear cover. Inspect the spur gear for wear and check the tightness of the set screws in the pinion gears. Tighten, clean, or replace components as needed.

Storage When you are through running the model for the day, blow it off with compressed air or use a soft bristled paint brush to dust off the vehicle.

Always disconnect and remove the battery from the model whenever the model is stored. If the model will be stored for a long time, also remove the batteries from the transmitter.

Suspension and slipper clutch assembly removal The your model was designed with ease of disassembly in mind. The entire front and rear suspension assemblies can be removed from the chassis fully intact with the removal of only a few screws.

ADVANCED TUNING ADJUSTMENTS

CAMBER GAIN

Your model has provisions for adjusting the camber gain geometry of the

front and rear suspension. “Camber gain” refers to an increase in camber

angle as the suspension is compressed. The camber gain of the vehicle

can be changed by moving the camber link attachment to a different

horizontal mounting position. Adjusting the camber gain will alter the tire

contact patch as the suspension is compressed. Making the camber link

shorter will increase the camber gain. This makes the vehicle more stable

over bumps, but reduces traction on smooth surfaces. Lengthening the

camber links has the opposite effect.

Front

· Front Camber Gain

To increase the camber gain on the front

suspension, move the inner camber link

ends out to Position 3. Position 4 is the stock

setting.

· Rear Camber Gain

Rear

To increase the camber gain on the rear

suspension, move the inner camber link

ends out to a different attachment hole

(Position 4 in the image. Position 5 is the

stock setting).

Once you make adjustments to the camber gain, you may need to re-adjust the static camber to suit your tuning needs.

ROLL CENTER Your model has provisions for adjusting the roll center geometry of the front and rear suspension. Roll center refers to the virtual axis around which the chassis will roll when subjected to cornering forces. The roll center of the vehicle can be raised by mounting the inner ends of the camber links in a lower position. Raising the roll center will effectively increase the roll stiffness of the vehicle (similar to installing swaybars). Adding roll resistance to one end of the vehicle will tend to add traction to the opposite end. For example, increasing roll resistance in the rear will provide more traction for the front wheels and potentially more steering. Raising the roll center on the front and rear equally will increase overall roll resistance without changing the handling balance. The default factory locations are designed to make the truck easier and more forgiving to drive and less likely to traction roll in turns.

· Rear Roll Center To lower the roll center on the rear suspension, relocate the inner camber links to one of the three holes (position 1, 2 or 3 in image) in the upper row of the rear camber link attachment, located near the base of the rear shock tower.

Once you make adjustments to the roll center, you may need to re-adjust the static camber to suit your tuning needs.

GEARING One of the more significant advantages to your model’s transmission is the extremely wide range of available gear ratios. Changing the gearing allows you to fine tune the speed of the model and control the temperatures of the battery pack and motor. Use a lower gear ratio (numerically larger) to reduce current draw and temperatures. Use a higher gear (numerically lower) to increase top speed. Use the following formula to calculate the overall ratio for combinations not listed on the gear chart:

Spur Gear Teeth x 2.85 = Final Gear Ratio # Pinion Gear Teeth

Always use the proper length motor bolts. The standard motor mounting bolts are 3x8mm. Using motor bolts that are too long can interfere with the motor’s rotation and damage the motor’s internal parts!
The VXL-3s features Locked Rotor Protection. The VXL-3s checks to make sure the motor is turning. If the motor is locked or damaged, the ESC will enter fail-safe until the motor is free to rotate.

ADVANCED TUNING ADJUSTMENTS

When using higher gear ratios, it is important to monitor the temperatures of the battery and motor. If the battery is extremely hot (150°F) and/or the motor is too hot to touch (200°F), your model is probably over-geared and drawing too much current. This temperature test assumes that the model is close to factory stock weight and operates freely with no excessive friction, dragging, or binding, and the battery is fully charged and in good condition. Note: Check and adjust gear mesh if a spur and/or pinion gear is changed.
This model is equipped with a Velineon 3500 motor. The gear combination that comes stock on each model provides good overall acceleration and top speed. If you want more top speed, install the included optional large pinion gear (more teeth). The included optional large pinion gear is intended for high-speed running on hard surfaces, and this gearing is not recommended for off-road or repetitive starting and stopping.
LIPO BATTERIES LiPo batteries are intended only for the most advanced users that are educated on the risks associated with LiPo battery use. It is critical to follow all instructions supplied by the battery manufacturer and the charger manufacturer for proper charging, use, and storage of LiPo batteries. Make sure you understand how to use your LiPo batteries. See safety precautions and warnings on page 4 for more information.

TEMPERATURES AND COOLING Monitoring temperatures will extend the lives of the batteries and motors. There are many options available that will help you monitor temperatures and cool your components .
Temperature sensor To accurately monitor motor temperature and prevent overheating, a telemetry temperature sensor (part #6523) can be installed on the motor to continually monitor temperature as you drive. Generally, try to keep your motor below 200° F. If necessary, increase airflow to the motor by cutting out the rear of the body or windshield.
Heat sink cooling fan The VXL-3s is equipped with an additional connector to supply power to an optional heat sink cooling fan (part #3340). The optional heat sink cooling fan can assist in cooling the VXL-3s in high current motor applications.

ADVANCED TUNING ADJUSTMENTS

TUNING THE SEALED GEAR DIFFERENTIALS The action of the your model’s front and rear gear differentials can be tuned for different driving conditions and performance requirements, without major disassembly or removal of the suspension system.
From the factory, the differentials are sealed to maintain consistent long- term performance. Changing the oil in the differential with either lower or higher viscosity oil will vary the performance characteristics of the differentials. Changing to a higher viscosity oil in the differential will reduce the tendency for motor power to be transferred to the wheel with the least traction. You may notice this when making sharp turns on slick surfaces. The unloaded wheels on the inside of the turn have the least traction and tend to spin up to extremely high rpms. Higher viscosity (thicker) oil causes the differential to act like a limited-slip differential, distributing more equal power to the left and right wheels.
Your model will generally benefit from higher viscosity oil when climbing or racing on low-traction surfaces. Note: Heavier oil will allow power to be transferred even with one or more tires off the ground. This can make the vehicle more likely to overturn on hightraction surfaces.
From the factory, the front differential is filled with SAE 30,000W viscosity silicone oil. The rear differential is filled with grease, but can also be tuned with silicone differential oil.
Only use silicone oil in the differentials. Traxxas offers SAE 10,000W, 30,000W, and 50,000W viscosity oil (see your parts list). The differentials have to be removed from the vehicle and disassembled to change/replace oil.

Follow the steps below to access and refill the front and rear differentials:
Front differential: 1. Remove the two 3x15mm button-head screws that secure the
top bumper mount to the differential (diff) case. 2. Turn the chassis over and remove the three 4x10mm countersunk
screws that hold bumper/skid plate to the bulkhead. The two rear screws do not need to be removed. 3. Slide bumper assembly off of the chassis. 4. Remove 3x15mm button-head screw from diff tie bar. 5. Slide tie bar off truck. 6. Remove two 3x15mm button-head screws from diff cover. Do not remove the two screws that secure the shock tower. 7. Use a 1.5mm hex wrench to remove the two screw pins that hold the driveshaft yokes to the differential output shafts. Remove the differential cover and slide the differential out of the front of the case. 8. To reinstall the differential, reverse the steps.

Refilling the differential: 1. Remove the four 2.5x10mm screws from the differential case
and carefully pull the diff case halves apart. Work over a towel to collect any fluid that drips from the differential.
2. Drain the fluid from the differential. You may wish to remove the spider gears from the differential to make this easier.
3. Place the spider gears back into the diff case, if you removed them. Fill the diff case with fluid until the spider gears are submerged half way.

4. Rejoin the diff case halves, using care to align the screw holes. Be sure the rubber gasket is in place, or the differential may leak.
5. Install the 2.5x10mm screws and tighten securely.
Center differential The optional center differential (part #6814, sold separately) allows the power from the motor to be transferred to the front and rear differentials independently from one another. When the rear wheels are under more load than the front wheels, more power will be transmitted to the front wheels. This is very beneficial on rough terrain and makes hard acceleration from low speeds easier to control by keeping the nose down. The center differential is assembled with 100K differential lube from the factory. This viscosity will be a good base point for most conditions.
1. Locate and remove the two 4x12mm button head machine screws from the top rear of the chassis and the two 4x14mm button head machine screws from the bottom of the rear suspension bulkhead (see page 26 for reference).
2. Remove the modular rear end from the chassis by sliding it backward away from the chassis. This is to access the spur gear/ slipper unit. Remove the spur gear/slipper unit from the rear of the chassis.
3. Insert the included center differential unit into the rear of the chassis (where the spur gear/slipper unit was removed). Stand the chassis up on the front bumper to hold the spur gear steady and line it up with the pinion gear. The splined shaft adapter must key into the aluminum center drive shaft.
4. Attach the rear end unit to the chassis keying in the rear output shaft of the center differential with the opening in the rear differential. Secure the assembly with the same four buttonhead screws. Tip: Rotate the rear wheels slowly while attaching the rear end to the chassis to properly set the rear output shaft of the center differential into the rear differential. You should feel the rear end set into place. The rear skid plate should lock into the bottom of the chassis.
TUNING AND MAINTAINING THE SHOCKS
Rustler 4X4 Ultimate features high-performance GTR shocks that utilize friction-reducing titanium nitride shafts and hard-anodized bodies with PTFE- coated bores to provide the ultimate in precise damping control. The shocks are filled with 30W silicone fluid. You may wish to install lower-viscosity (“thinner”) or higher-viscosity (“thicker”) fluid to alter damping performance to suit your track, terrain, or driving style. Damping can also be altered by changing the pistons inside the shocks. The front piston is a 2-hole with 1.5mm diameter holes. The rear piston is a 2-hole with 1.6 diameter holes.

ADVANCED TUNING ADJUSTMENTS

Shock Oil The 4 oil-filled aluminum shocks (dampers) effectively control the suspension movement by preventing the wheels and tires from continuing to “bounce” after rebounding from a bump. Changing the oil in the shocks can vary the suspension damping effect. Changing the oil to a higher viscosity oil will increase damping. Lowering the viscosity of the oil will cause the suspension damping to be reduced. Damping should be increased (with higher viscosity oil) if the model is bottoming easily over jumps. Damping should be decreased (with thinner viscosity oil) if the model is hopping over small bumps and feels unstable. The viscosity of shock oil is affected by extremes in operating temperature; an oil of certain viscosity will become less viscous at higher temperatures and more viscous at lower temperatures. Operating in regions with cold temperatures may require lower viscosity oil. From the factory, the shocks are filled with SAE-30W silicone oil. Only use 100% silicone oil in the shock.

Replacing Shock Oil For easier service, the shocks should be removed from the vehicle and disassembled to change the oil.
1. Remove the lower spring retainer and shock spring.
2. Remove the upper shock cap using the shock wrench and suspension multitool (A).
3. Empty the used shock oil from the shock body.
4. Fill the shock with new silicone shock oil up to the top of the shock body.
5. Slowly move the piston up and down (always keeping it submerged in oil) to release the air bubbles. Let the shock sit for a few minutes to allow any remaining air bubbles to surface.
6. Slowly thread the upper cap with the installed shock bladder onto the shock body with the suspension multi-tool. The excess oil will bleed out of the small hole in the shock cap.
7. Tighten the shock cap until snug. Use the included steel shock wrench to hold onto the shock body while tightening (A).

1. Remove the spring and lower spring retainer from the shock.
2. Remove the shock cap and empty the shock body of shock oil (A).
3. Remove the lower cap and the X-ring from the shock body (B).
4. Use side cutters to grip the shock shaft just above the rod end. Remove the rod end from the shock shaft using the suspension multitool (C).
5. Remove the shock shaft with piston from the shock body out through the top of the shock body.

Shock assembly 1. Replace the stock piston with desired
optional piston. Be careful not to lose the small washer located below the piston.
2. Position the new piston onto the shock shaft above the small washer. Grip the threads of the shaft with side cutters or needlenose pliers and tighten the nut with the 4-way wrench to secure the assembly (D).
3. Insert the shock shaft assembly through the shock body until the piston bottoms out.
4. Lubricate the shaft and X-ring with silicone oil.
5. Install the X-ring over the shaft and into the bore of the shock body.
6. Install the lower cap using the suspension multi-tool (B).
7. Grip the shaft close to the threads with needlenose pliers or side cutters and thread the rod end onto the shock shaft until the rod end bottoms out (C).

Throttle Trim Seek Mode When the Multi-Function knob is set to throttle trim, the transmitter remembers the throttle trim setting. If the throttle trim knob (Multi-Function knob) is moved from the original setting while the transmitter is off, or while the transmitter was used to control another model, the transmitter ignores the actual position of the trim knob. This prevents the model from accidentally running away. The LED on the face of the transmitter will rapidly blink green and the throttle trim knob (Multi-Function knob) will not adjust the trim until it is moved back to its original position saved in memory. To restore throttle trim control, simply turn the Multi-Function knob either direction until the LED stops blinking.
Fail-safe Your Traxxas radio system is equipped with a built-in fail-safe function that returns the throttle to its last saved neutral position in the event of a signal loss. The LED on the transmitter and the receiver will rapidly flash red.
Starting Over: Restoring Factory Defaults When programming your TQi transmitter, you may feel the need to start over with a clean slate. Follow these simple steps to restore the factory settings:
1. Turn the transmitter off. 2. Hold both MENU and SET. 3. Turn the transmitter on. 4. Release MENU and SET. The
transmitter LED will blink red. 5. Press SET to clear settings. The
LED will turn solid green and the transmitter is restored to default.

Available Tuning Adjustments The following items can be adjusted most easily using your mobile device and the Traxxas Link application. All the features described below may also be accessed using the MENU and SET buttons on the transmitter and observing signals from the LED. An explanation of the menu structure follows on page 37.
Your Traxxas transmitter has a programmable Multi-Function knob that can be set to control various advanced transmitter functions (set to Traxxas Stability Management by default, see page 16). Experiment with the settings and features to see if they can improve your driving experience.
Steering Sensitivity (Exponential) The Multi-Function knob on the TQi transmitter can be set to control Steering Sensitivity (also known as exponential). The standard setting for Steering Sensitivity is “normal (zero exponential),” with the dial full left in its range of travel. This setting provides linear servo response: the steering servo’s movement will correspond exactly with the input from the transmitter’s steering

wheel. Turning the knob clockwise from center will result in “negative exponential” and decrease steering sensitivity by making the servo less responsive near neutral, with increasing sensitivity as the servo nears the limits of its travel range. The farther you turn the knob, the more pronounced the change in steering servo movement will be. The term “exponential” comes from this effect; the servo’s travel changes exponentially relative to the input from the steering wheel. The exponential effect is indicated as a percentage–the greater the percentage, the greater the effect. The illustrations below show how this works.
Normal Steering Sensitivity (0% exponential): In this illustration, the steering servo’s travel (and with it, the steering motion of the model’s front wheels) corresponds precisely with the steering wheel. The ranges are exaggerated for illustrative purposes.

Decreased Steering Sensitivity (Negative Exponential):

Turning Range at Transmitter

Effective Turning Range on Model

By turning the Multi-Function

knob clockwise, the steering

sensitivity of the model will be

decreased. Note that a relatively

large amount of steering wheel

travel results in a smaller

amount of servo travel. The

farther you turn the knob, the

more pronounced the effect

becomes. Decreased steering

sensitivity may be helpful when driving on low-traction surfaces, when driving at

high speed, or on tracks that favor sweeping turns where gentle steering inputs are

required. The ranges are exaggerated for illustrative purposes.

Throttle Sensitivity (Throttle Exponential) The Multi-Function knob can be set to control Throttle Sensitivity. Throttle Sensitivity works the same way as Steering Sensitivity, but applies the effect to the throttle channel. Only forward throttle is affected; brake/reverse travel remains linear regardless of the Throttle Sensitivity setting.
Steering Percentage (Dual Rate) The Multi-Function knob can be set to control the amount (percentage) of servo travel applied to steering. Turning the MultiFunction knob fully clockwise will deliver maximum steering throw; turning the knob counterclockwise reduces steering throw (note: turning the dial counterclockwise to its stop will eliminate all servo travel). Be aware that the steering End Point settings define the servo’s maximum steering throw. If you set Steering Percentage to 100% (by turning the Multi-Function knob fully clockwise), the servo will travel all the way to its selected end point, but not past it. Many racers set Dual Rate so they have only as much steering throw as they need for the track’s tightest turn, thus making the car easier to drive throughout the rest of the course. Reducing steering throw can also be useful in making a car easier to control on high-traction surfaces, and limiting steering output for oval racing where large amounts of steering travel are not required.

Steering and Throttle End Points The TQi transmitter allows you to choose the limit of the servo’s travel range (or its “end point”) independently for left and right travel (on the steering channel) and throttle/brake travel (on the throttle channel). This allows you to fine-tune the servo settings to prevent binding caused by the servo moving steering or throttle linkages (in the case of a nitro car) farther than their mechanical limits. The end point adjustment settings you select will represent what you wish to be the servo’s maximum travel; the Steering Percentage or Braking Percentage functions will not override the End Point settings.
Steering and Throttle Sub-Trim The Sub-Trim function is used to precisely set the neutral point of the steering or throttle servo in the event that simply setting the trim knob to “zero” does not completely center the servo. When selected, Sub-Trim allows finer adjustment to the servo output shaft’s position for precise setting of the neutral point. Always set the Steering Trim knob to zero before making final adjustment (if required) using Sub-Trim. If Throttle Trim has been previously adjusted, the Throttle Trim will need to be reprogrammed to “zero” before making final adjustment using Sub-Trim.
Braking Percentage The Multi-Function knob may also be set to control the amount of brake travel applied by the servo in a nitro-powered model. Electric models do not have a servo-operated brake, but the Braking Percentage function still operates the same way in electric models. Turning the Multi-Function knob full clockwise will deliver maximum brake throw; turning the knob counterclockwise reduces brake throw (Note: Turning the dial counterclockwise to its stop will eliminate all brake action).
Throttle Trim Setting the Multi-Function knob to serve as throttle trim will allow you to adjust the throttle’s neutral position to prevent unwanted brake drag or throttle application when the transmitter trigger is at neutral. Note: Your transmitter is equipped with a Throttle Trim Seek mode to prevent accidental runaways. See the sidebar on page 34 for more information.

TQi ADVANCED TUNING GUIDE

Setting Lock Once you’ve adjusted all of these settings the way you like them, you may want to disable the Multi-Function knob so none of your settings can be changed. This is especially handy if you operate multiple vehicles with a single transmitter via Traxxas LinkTM Model Memory.
Multiple Settings and the Multi-Function Knob It is important to note that settings made with the Multi-Function knob are “overlaid” on top of each other. For example, if you assign the Multi-Function knob to adjust Steering Percentage and set it for 50%, then reassign the knob to control Steering Sensitivity, the transmitter will “remember” the Steering Percentage setting. Adjustments you make to Steering Sensitivity will be applied to the 50% steering throw setting you selected previously. Likewise, setting the Multi- Function knob to “disabled” will prevent the knob from making further adjustments, but the last setting of the MultiFunction knob will still apply.
TRAXXAS LINK MODEL MEMORY Traxxas Link Model Memory is an exclusive, patent- pending feature of the TQi transmitter. Each time the transmitter is bound to a new receiver, it saves that receiver in its memory along with all the settings assigned to that receiver. When the transmitter and any bound receiver are switched on, the transmitter automatically recalls the settings for that receiver. There is no need to manually select your vehicle from a list of model memory entries.
Model Lock The Traxxas Link Model Memory feature can store up to thirty models (receivers) in its memory. If you bind a thirty-first receiver, Traxxas Link Model Memory will delete the “oldest” receiver from its memory (in other words, the model you used the longest time ago will be deleted). Activating Model Lock will lock the receiver in memory so it cannot be deleted.
You may also bind multiple TQi transmitters to the same model, making it possible to pick up any transmitter and any previously bound model in your collection and simply turn them on and drive. With Traxxas Link Model Memory, there is no need remember which transmitter goes with which model and there is never a need to have to select any model from a list of model memory entries. The transmitter and receiver do it all for you automatically.

To activate Model Lock: 1. Switch on the transmitter and receiver you wish to lock.
2. Press and hold MENU. Release when the status LED blinks green.
3. Press MENU three times. The status LED will blink green four times repeatedly.
4. Press SET. The status LED will blink green in singleflash intervals.
5. Press SET once. The status LED will blink red once repeatedly.
6. Press MENU once. The LED will blink red twice repeatedly.
7. Press SET. The LED will blink rapidly green. The memory is now locked. Press MENU and SET to return to driving mode.
Note: To unlock a memory, press SET twice at step 5. The LED will blink rapidly green to indicate the model is unlocked. To unlock all models, press MENU twice at step 6 and then press SET.
To delete a model: At some point, you may wish to delete a model you no-longer drive from the memory.
1. Switch on the transmitter and receiver you wish to delete.
2. Press and hold MENU. Release when the status LED blinks green.
3. Press MENU three times. The status LED will blink green four times repeatedly.
4. Press SET once. The status LED will blink green once repeatedly.
5. Press MENU once. The status LED will blink green twice repeatedly.
6. Press SET. The memory is now selected to be deleted. Press SET to delete the model. Press and hold MENU to return to driving mode.
