Important Points to Remember

• Your model is not intended for use on public roads or congested areas where its operation can conflict with or disrupt pedestrian or vehicular traffic.

• Never, under any circumstances, operate the model in crowds of people. Your model is very fast and could cause injury if allowed to collide with anyone.

• Because your model is controlled by radio, it is subject to radio interference from many sources that are beyond your control. Since radio interference can cause momentary losses of radio control, always allow a safety margin in all directions around the model in order to prevent collisions. • The motor, battery, and speed control can become hot during use. Be careful to avoid getting burned. • Don’t operate your model at night, or anytime your line of sight to the model may be obstructed or impaired in any way.

Most importantly, use good common sense at all times.

Speed Control

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

Disconnect the Battery:

Always disconnect the battery or batteries from the speed control when not in use. •

Insulate the Wires:

Always insulate exposed wiring with heat shrink tubing to prevent short circuits.

Transmitter on First:

performance.

Switch on your transmitter first before switching on the speed control to prevent runaways and erratic •

Don’t Get Burned:

The ESC and motor can become extremely hot during use, so be careful not to touch them until they cool. Supply adequate airflow for cooling.

Use the Factory-Installed Connectors:

Do not change the battery and motor connectors. Improper wiring can cause fire or damage to the ESC. Please note that modified speed controls can be subject to a rewiring fee when returned for service.

No Reverse Voltage:

The ESC is not protected against reverse polarity voltage. •

SAFETY PRECAUTIONS

WARNING! CAUTION! DANGER!

Your model is able to use LiPo batteries. Charging and discharging batteries has the potential for fire, explosion, serious injury, and property damage if not performed per the instructions. Before use, read and follow all manufacturer’s instructions, warnings, and precautions. In addition, Lithium Polymer (LiPo) batteries pose a SEVERE risk of fire if not properly handled per the instructions and require special care and handling procedures for long life and safe operation. LiPo batteries are intended only for advanced users that are educated on the risks associated with LiPo battery use. Traxxas does not recommend that anyone under the age of 14 use or handle LiPo battery packs without the supervision of a knowledgeable and responsible adult. Dispose of used batteries according to the instructions.

Important Warnings for users of Lithium Polymer (LiPo) batteries: • LiPo batteries have a minimum safe discharge voltage threshold that should not be exceeded. The electronic speed control is equipped with built-in Low-Voltage Detection that alerts the driver when LiPo batteries have reached their minimum voltage (discharge) threshold. It is the driver’s responsibility to stop immediately to prevent the battery pack from being discharged below its safe minimum threshold.

• Low-Voltage Detection is just one part of a comprehensive plan for safe LiPo battery use. It is critical to follow all instructions for safe and proper charging, use, and storage of LiPo batteries. Make sure you understand how to use your LiPo batteries. If you have questions about LiPo battery usage, please consult with your local hobby dealer or contact the battery manufacturer. As a reminder, all batteries should be recycled at the end of their useful life.

• ONLY use a Lithium Polymer (LiPo) balance charger with a balance adapter port to charge LiPo batteries. Never use NiMH or NiCad type chargers or charge modes to charge LiPo batteries. DO NOT charge with a NiMH-only charger. The use of a NiMH or NiCad charger or charge mode will damage the batteries and may cause fire and personal injury.

• NEVER charge LiPo battery packs in series or parallel. Charging packs in series or parallel may result in improper charger cell recognition and an improper charging rate that may lead to overcharging, cell imbalance, cell damage, and fire. • ALWAYS inspect your LiPo batteries carefully before charging. Look for any loose leads or connectors, damaged wire insulation, damaged cell packaging, impact damage, fluid leaks, swelling (a sign of internal damage), cell deformity, missing labels, or any other damage or irregularity. If any of these conditions are observed, do not charge or use the battery pack. Follow the disposal instructions included with your battery to properly and safely dispose of the battery. • DO NOT store or charge LiPo batteries with or around other batteries or battery packs of any type, including other LiPos.

• Store and transport your battery pack(s) in a cool dry place. DO NOT store in direct sunlight. DO NOT allow the storage temperature to exceed 140°F or 60°C, such as in the trunk of a car, or the cells may be damaged and create a fire risk. • DO NOT disassemble LiPo batteries or cells.

• DO NOT attempt to build your own LiPo battery pack from loose cells.

Charging and handling precautions for all battery types: • BEFORE you charge, ALWAYS confirm that the charger settings exactly match the type (chemistry), specification, and configuration of the battery to be charged. • DO NOT attempt to charge non-rechargeable batteries (explosion hazard), batteries that have an internal charge circuit or a protection circuit, batteries that have been altered from original manufacturer configuration, or batteries that have missing or unreadable labels, preventing you from properly identifying the battery type and specifications.

• DO NOT exceed the maximum manufacturer recommended charge rate.

• DO NOT let any exposed battery contacts or wires touch each other. This will cause the battery to short circuit and create the risk of fire.

• While charging or discharging, ALWAYS place the battery (all types of batteries) in a fire retardant/fire proof container and on a non-flammable surface such as concrete.

• DO NOT charge batteries inside of an automobile. DO NOT charge batteries while driving in an automobile. • NEVER charge batteries on wood, cloth, carpet, or on any other flammable material.

2.4GHz RADIO 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 29) and Menu Tree (page 32) 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 29.

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 TQ

i

2.4GHz RADIO 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 steering. - 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

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

Brake/Reverse Forward

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

1

Always turn your transmitter on first.

2

Plug in the battery.

3

Turn on the model.

• Always use new batteries for the radio system. Weak batteries will limit the radio signal between the receiver and the transmitter.

Loss of the radio signal can cause you to lose control of your model.

• In order for the transmitter and receiver to bind to one another, the receiver in the model must be turned on within 20 seconds of turning on the transmitter. The transmitter LED will flash fast red, indicating a failure to link. If you miss it, simply turn off the transmitter and start over.

• Always turn on the transmitter before plugging in the battery.

RADIO SYSTEM BASIC ADJUSTMENTS

Throttle Neutral Adjustment

The throttle neutral adjustment is located on the transmitter face and controls the forward/ reverse travel of the throttle trigger. Change the adjustment by pressing the button and sliding it to the desired position. There are two settings available:

50/50

: Allows equal travel for both acceleration and reverse.

70/30

: Allows more throttle travel (70%) and less reverse travel (30%).

Note: We strongly recommend to leave this control in its factory location until you become familiar with all the adjustments and capabilities of your model.

position. To change the throttle neutral adjust position, turn the transmitter off before adjusting the neutral

You will need to reprogram your electronic speed control to recognize the 70/30 setting.

Turn to ESC Setup Programming on page 18 for instructions.

Steering Trim

The electronic steering trim located on the face of the transmitter adjusts the neutral (center) point of the steering channel.

Note:

Traxxas Stability Management (TSM) must be completely turned off while adjusting steering trim. See page 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 detail on TSM, refer to page 17.

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 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.

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. Press and release the EZ-Set button on the speed control to turn the model on. The LED will shine RED or GREEN (see note below). To turn the VXL-3s off, press the set button until the LED turns off.

Note

: If the LED shines green after the speed control is turned on, Low-Voltage Detection is activated. This may cause poor performance from NiMH battery packs. Make sure to turn the Low-Voltage Detection on when using LiPo batteries. See page 18 for more information.

Never use LiPo batteries while Low-Voltage Detection is turned off.

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 car’s running area, not the far end, so you drive the car 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.” each other.

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 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.

ADJUSTING THE ELECTRONIC SPEED CONTROL

VXL-3s Battery Settings (Low-Voltage Detection Setting)

The Velineon VXL-3s electronic speed control is equipped with built-in Low-Voltage Detection. The Low-Voltage Detection circuitry constantly monitors the battery voltage. When the battery voltage begins to reach the minimum recommended discharge voltage threshold for LiPo battery packs, the 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. The VXL-3s speed control’s Low-Voltage Detection has been disabled for best performance with NiMH batteries. The speed control’s LED will glow red when it is turned on, indicating Low-Voltage Detection is disabled. Be certain to activate Low-Voltage Detection if you install a LiPo battery in your model.

Never use LiPo batteries while Low-Voltage Detection is disabled. Verify that Low-Voltage Detection is DISABLED:

1. Turn on the transmitter (with the throttle at neutral).

2. Connect a fully charged battery pack to the VXL-3s. 3. Press and release the EZ-Set button to turn the VXL-3s on. If the LED is solid red, then the Low-Voltage Detection is DISABLED (not safe to use LiPo batteries). If the LED is solid green, then Low-Voltage Detection is ACTIVATED.

To activate Low-Voltage Detection (LiPo setting):

1. Make sure the LED on the VXL-3s is on and red. 2. Press and hold the EZ-Set button for ten seconds. The LED will turn off and then light green. Also, a “rising” musical tone will be emitted from the motor.

3. Low-Voltage Detection is now ACTIVATED.

To disable Low-Voltage Detection (NiMH setting):

1. Make sure the LED on the VXL-3s is on and green. 2. Press and hold the EZ-Set button for ten seconds. The LED will turn off and then light red. Also, a “falling” musical tone will be emitted from the motor.

3. Low-Voltage Detection is now DISABLED.

Transmitter Adjustments for the VXL-3s ESC

Before attempting to program your VXL-3s ESC, it is important to make sure that your transmitter is properly adjusted (set back to the factory defaults). Otherwise, you may not get the best performance from your speed control.

The transmitter should be adjusted as follows:

If the transmitter setting have been adjusted, reset them to the factory defaults. 1. Turn transmitter off.

2. Hold both MENU and SET.

3. Turn 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.

VXL-3s Setup Programming (Calibrating your ESC and transmitter)

Read through all of the programming steps before you begin. If you get lost during programming or receive unexpected results, simply unplug the battery, wait a few seconds, plug the battery back in, and start over.

wheels are off the ground. Disconnect motor wires “A” and “C” (see page 12), this will assure the motor does not drive the wheels during testing. Do not test programming without disconnecting the motor wires.

Note that in steps 1-7 below, Low-Voltage Detection is DISABLED (factory default) and the LED shines red. If Low-Voltage Detection is ACTIVATED, the LED will shine green instead of red in steps 1-7 below.

Never use LiPo batteries while Low-Voltage Detection is disabled.

1. With the transmitter on, press and release the EZ-Set button. The LED will shine red. This turns the VXL-3s on. 2. Apply forward throttle. The LED will turn off until full throttle power is reached. At full throttle, the LED will illuminate red.

3. Move the trigger forward to apply the brakes. Note that braking control is fully proportional. The LED will turn off until full braking power is reached. At full brakes, the LED will illuminate red.

4. Return the throttle trigger to neutral. The LED will shine red.

5. Move the throttle trigger forward again to engage reverse (Profile #1). The LED will turn off. Once full reverse power is reached, the LED will illuminate red. 6. To stop, return the throttle trigger to neutral. Note that there is programmed delay when changing from reverse to forward. This prevents damage to the transmission on high-traction surfaces.

7. To turn the VXL-3s off, press the EZ-Set button until the LED turns off (.5 seconds).

DRIVING YOUR MODEL

Now it’s time to have some fun! This section contains instructions on driving and making adjustments to your model.

Before you go on, here are some important precautions to keep in mind.

• Allow the model to cool for a few minutes between runs. This is particularly important when using high-capacity (2400mAh and above) battery packs that allow extended periods of running. Monitoring temperatures will extend the lives of the batteries and motor.

• Do not continue to operate the model with low batteries or you could lose control of it. Indications of low battery power include slow operation and sluggish servos (slow to return to center). Stop immediately at the first sign of weak batteries. When the batteries in the transmitter become weak, the red power light will begin to flash. Stop immediately and install new batteries.

• Do not drive the model at night, on public streets, or in large crowds of people.

• If the model becomes stuck against an object, do not continue to run the motor. Remove the obstruction before continuing. Do not push or pull objects with the model.

• Because the model is controlled by radio, it is subject to radio interference from many sources beyond your control. Since radio interference can cause momentary losses of control, allow a safety margin of space in all directions around the model in order to prevent collisions.

• Use good, common sense whenever you are driving your model. Intentionally driving in an abusive and rough manner will only result in poor performance and broken parts. Take care of your model so that you can enjoy it for a long time to come.

• When using optional pinions for top speed running, limit your driving to paved surfaces only. Repetitive starting and stopping and extensive drifting around turns will create excess heat and overheat the ESC and/or motor. Running in grass and off-road could also cause excessive loads on the electrical system. • The Titan 12T motor will benefit from a short break-in period to ensure optimum performance and longer motor life. For the first battery pack, use the stock installed pinion gear and drive smoothly on a flat, paved surface. Accelerate smoothly (avoiding full throttle starts), with most of the driving being done at higher speeds. This will help ensure that the motor provides the best performance and longest life.

About Run Time

A large factor affecting run time is the type and condition of your batteries. The milliamp hour (mAh) rating of the batteries determines how large their “fuel tank” is. A 3000 mAh battery pack will theoretically run twice as long as a 1500 mAh sport pack. Because of the wide variation in the types of batteries that are available and the methods with which they can be charged, it’s impossible to give exact run times for the model.

Another major factor that affects run time is how the model is driven. Run times may decrease when the model is driven repetitively from a stop to 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.

• Vary your speed. The Titan12T is a fan cooled motor, therefore moderate to top-speed running helps reduce motor temperatures. • Lower your gear ratio. Installing a smaller pinion gear will lower your gear ratio, causing less power draw from the motor.

• Maintain your model. Do not allow dirt or damaged parts to cause binding in the drivetrain. Keep the motor clean and the motor bushings lightly lubricated.

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.

DRIVING YOUR MODEL

RUNNING IN WET CONDITIONS

Your new Traxxas model is designed with water-resistant features to protect the electronics in the model (receiver, servos, electronic speed control). This gives you the freedom to have fun driving your model through puddles, wet grass, snow, and through other wet conditions. Though highly water resistant, the model should not be treated as though it is submersible or totally, 100% waterproof. Water resistance applies only to the installed electronic components. Running in wet conditions requires additional care and maintenance for the mechanical and electrical components to prevent corrosion of metal parts and maintain their proper function.

Precautions • Without proper care, some parts of your model can be seriously damaged due to contact with water. Know that additional maintenance procedures will be required after running in wet conditions in order to maintain the performance of your model. Do not run your model in wet conditions if you are not willing to accept the additional care and maintenance responsibilities.

• Not all batteries can be used in wet environments. Consult your battery manufacturer to see if their batteries can be used in wet conditions. • The Traxxas TQi 2.4GHz 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.

• Even casual water contact can reduce the life of your motor. Special care must be taken to modify your gearing and/or your driving style in wet conditions to extend the life of the motor (details follow).

Before Running Your Vehicle in Wet Conditions

1. Consult the section “After Running Your Vehicle in Wet Conditions” before proceeding. Make sure you understand the additional maintenance required with wet running.

2. The wheels have small holes molded in to allow air to enter and exit the tire during normal running. Water will enter these holes and get trapped inside the tires if holes are not cut in the tires. Cut two small holes (3mm or 1/8” diameter) in each tire. Each hole should be near the tire centerline, 180 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 visible 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 19T, with the stock 70-T spur gear) 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

• Titan motor life can be greatly reduced in mud and water. If the motor gets excessively wet or submerged, use very light throttle (run the motor slowly) until the excess water can run out. Applying full throttle to a motor full of water can cause rapid motor failure. Your driving habits will determine motor life with a wet motor. Do not submerge the motor under water.

• Do not gear the motor by temperature when running in wet conditions. The motor will be cooled by water contact and will not give an accurate indication of appropriate gearing.

After Running Your Vehicle in Wet Conditions

1. Drain the tires by spinning the tires at high speed to “sling” the water out. One way to do this is to make several high-speed passes on a flat, dry surface, if possible.

2. Remove the batteries.

3. Rinse excess dirt and mud off the car with low-pressure water, such as from a garden hose. Do NOT use pressure washer or other high-pressure water. Avoid directing water into the bearings, transmission, etc.

4. Blow off the car with compressed air (optional, but recommended). Wear safety glasses when using compressed air. 5. Remove the wheels from the car.

6. Spray all the bearings, drivetrain, and fasteners with WD-40 ® or similar water displacing light oil.

TRAXXAS • 21

22 • TRAXXAS DRIVING YOUR MODEL 7. Let the car stand or you may blow off with compressed air. Placing the car in a warm, sunny spot will aid drying. Trapped water and oil will continue to drip from the car 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

RECEIVER BOX: MAINTAINING A WATERTIGHT SEAL

Removing and Installing Radio Gear

The unique design of the receiver box allows the removal and installation of the receiver without losing the ability to maintain a watertight seal in the box. The patent-pending wire clamp feature gives you the ability to also install aftermarket radio systems and maintain the watertight features of the receiver box.

Removing the Receiver

1. To remove the cover, remove the three 2.5x10mm socket-head cap screws.

2. To remove the receiver from the box, simply lift it out and set to the side. 3. Unplug the servo cables from the receiver and remove the receiver.

Receiver Installation

1. Always install the wires into the receiver box before installing the receiver.

2. Install the antenna wire and the servo cables into the receiver box.

3. Arrange the wires neatly using the wire guides in the receiver box. The excess wire will be bundled inside the receiver box. Label which wire is for which channel.

4. Apply a small bead of silicone grease (Traxxas part #1647) to the wire clamp. 5. Using double-sided adhesive foam tape, install the receiver into the box.

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

6. Plug the wires into the receiver. Refer to page 12 for the wiring diagram.

7. Make sure the box light pipe is aligned with the receiver LED. Make sure the O-ring is properly seated into the groove in the receiver box so that the cover will not pinch it or damage it in any way. 8. Install the cover and tighten the three 2.5x10mm socket-head cap screws securely.

9. Inspect the cover to make sure that the O-ring seal is not visible.

ADJUSTING YOUR MODEL

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. Your model includes a fixed gear positioning system to simplify the process and ensure proper gear mesh settings. Access the gears by removing the four 3x12mm button-head cap screws from the gear cover; remove the gear cover. Remove the motor/motor plate assembly from the chassis.

To set the gear mesh, use the chart in the sidebar to identify the screw positions on the motor plate (A - K) that correspond with the chosen motor pinion gear size. Remove the two screws from the motor/ motor plate and reinstall in the corresponding positions; reinstall the motor/motor plate assembly in the chassis.

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 on-road performance.

Fine Tuning the Shocks

The four shocks on the model greatly influence its handling. Whenever you rebuild your shocks or make any changes to the pistons, springs, or oil, always make changes to them in pairs (front or rear). Piston selection depends on the range of oil viscosities that you have available. For example, using a two-hole piston with a lightweight oil will, at one point, give you the same damping as a three-hole piston with heavier oil. We recommend using the two-hole pistons with a range of oil viscosities from 10W to 50W (available from your hobby shop).

Pre-load Spacer

The thinner viscosity oils (30W or less) flow more smoothly and are more consistent, while thicker oils provide more damping. Use only 100% pure silicone shock oil to prolong seal life. The model’s ride height can be adjusted by adding or removing the clip-on, spring pre-load spacers. Adjust the ride height so that the suspension arms are slightly above being parallel to the ground. Observe how the model handles in turns. Proper set-up will add stability and help prevent spin outs. Experiment with different springs and shock oils to find what works best for your current track conditions.

Centering Your Servo

If the trim controls on your transmitter seem off, you may need to re-center your servo. Additionally, whenever your servo has been removed for service or cleaning, it must be re-centered prior to installation in the model. 1. Disconnect 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. 3. Place fresh “AA” batteries in the transmitter and turn the transmitter power switch on. 4. Turn off TSM (see page 17).

5. Turn the steering trim adjustment on the transmitter to the center “0” position.

6. Elevate the model on a block or stand so that all of the tires are off the ground. Connect a fresh battery pack to the speed control and turn on the ESC (see page 18). The servo will automatically jump to its center position.

Be careful not to move the servo shaft when installing the servo horn. Readjust the ESC as described in the “Adjusting the Electronic Speed Control” section.

Motors and Gearing

One of the more significant advantages to your model’s transmission is the extremely wide range of available gear ratios. It can be geared low enough to run an extremely hot, modified motor. A higher kV motor should be geared lower (higher numerically) than a stock motor because it will reach its maximum power at higher rpms. A higher kV motor that is geared incorrectly can actually be slower than a correctly-geared, stock motor. Use the following formula to calculate the overall ratio for combinations not listed on the gear chart:

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

If you are worried that you might be over-geared, check the temperature of the battery pack and motor. If the battery is extremely hot, and/or the motor is too hot to touch, your model is probably over-geared. If you are not able to run your model for at least four minutes before the battery dies, then change to a lower gear ratio. This temperature test assumes that the model is close to factory stock weight and operates freely with no excessive friction, dragging, or binding, and the battery is fully charged and in good condition.

The 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 and less acceleration, install the included high-speed gearing (more teeth). If you want more acceleration and less top speed, use a smaller optional (not included) pinion gear.

The included high-speed gearing is intended for high-speed running on hard surfaces, and this gearing is not recommended for off-road or repetitive starting and stopping.

For this type of driving, smaller pinion gears are recommended to reduce load on the motor.

5000+ mAh Tuning the Sealed Gear Differentials

The action of the 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 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 high-traction surfaces. From the factory, the front differential is filled with SAE 30,000W viscosity silicone oil and the rear differential is filled with SAE 10,000W viscosity silicone 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 on the next page to access and refill the front and rear differentials.

CHASSIS ADJUSTABILITY

Adjustable Body Mounts

The 4-Tec 2.0 chassis features adjustable body mounts to accommodate many popular 200mm touring car body styles. To adjust the mounts forward or backward, simply remove the fixed screws and install them in the sliding channels. If you need to adjust for width, remove all four screws and pull the body posts out sideways. Reinsert the body posts in the opposite direction so that the screw will pass through the channel. Once you are satisfied with the positioning, tighten down the screws to secure the mounts. An optional set of fixed body mounts is also included with your model.

High-Angle Steering

The steering blocks on the 4-Tec 2.0 chassis feature a high-angle option when extra steering angle is desired (for example, when power drifting around a turn). First trim the plastic bump stop to allow greater range of motion from the steering blocks (see illustration). Next, drill out the inner hole on the steering block and move the steering link to the inner hole. When making this modification, we also recommend that you upgrade to constant velocity driveshafts (sold separately) to avoid driveshaft chatter.

Adjustable Wheelbase

The 4-Tec 2.0 chassis allows you to lengthen or shorten the wheelbase by up to 3mm for the perfect body fit. Remove the rear suspension arms from the vehicle and trim material from the front or rear of the arms. Save the material you remove and add it to the opposite side of the arms to act as a spacer, or use washers to shim the arms.

Note: The front suspension arms are not adjustable and should not be modified or trimmed.

ADJUSTING YOUR MODEL

Dual Rear Camber Link Mounts

There are two separate mounting points for the rear camber links. Changing the location does not affect performance, but will allow the use of different bodies. The lower mounting points should be used with low profile bodies; the upper mounting points will work with most body styles. Both mounting points feature two holes for wheel camber

Mounting Holes UPPER MOUNTING Mounting Holes LOWER MOUNTING

adjustment. Moving the links from the standard holes to the outer holes will increase camber and slightly reduce roll stiffness. This modification also requires adjustable camber links (part #8341X, sold separately) to lengthen the links and ensure proper camber settings.

Suspension Droop Adjustment

Suspension droop is the amount of downward travel on the wheels (how much the suspension arm hangs down when the chassis is off the ground). Molded screw bosses in the suspension arms allow you to adjust droop by using a 4mm set screw (part #4897, sold separately). Tightening the screw will decrease droop and allow you to tune the suspension for better stability when cornering. TRAXXAS • 27

Always wear eye protection when using compressed air or spray cleaners and lubricants.

MAINTAINING YOUR MODEL

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, servo, 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.

Other periodic maintenance:

Chassis

: Keep the chassis clean of accumulated dirt and grime. Periodically inspect the chassis for damage.

Suspension

: Periodically inspect the model for signs of damage, such as bent or dirty suspension pins, bent camber links, loose screws, and any signs of stress or bending. Replace components as needed.

Steering

: Over time, you may notice increased looseness in the steering system. Replace any components as needed to restore factory tolerances. •

Shocks

: Keep the oil level in the shocks full. Use only 100% pure silicone shock oil to prolong the life of the seals. If you are experiencing leakage around the top of the shock, inspect the bladder in the top cap for signs of damage or distortion from overtightening. If the bottom of the shock is leaking, then it is time for a rebuild. The Traxxas rebuild kit for two shocks is part #2362. •

Driveline Note:

: Inspect the driveline for signs of wear or any unusual noise or binding. Remove the gear cover and inspect the spur gear for wear and check the tightness of the set screw in the pinion gear. Tighten, clean, or replace components as needed.

When replacing the spur gear, be sure the spur gear is fully seated on the center driveshaft as shown. There will be an audible “click” as the gear is pushed into place.

Storage

When you are through running your 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 your model whenever the model is stored. If your model will be stored for a long time, then also remove the batteries from the transmitter.

ADVANCED TUNING GUIDE

Your Traxxas transmitter has a programmable Multi-Function knob that can be set to control various advanced transmitter functions (set to Traxxas Stability Management (TSM) by default, see page 17). Accessing the programming menu is done by using the menu and set buttons on the transmitter and observing signals from the LED. An explanation of the menu structure follows on page 32. 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):

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 exaggerated for illustrative purposes.

Turning Range at Transmitter Effective Turning Range on Model

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

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 Multi-Function 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 model easier to drive throughout the rest of the course. Reducing steering throw can also be useful in making a model easier to control on high-traction surfaces, and limiting steering output for oval racing where large amounts of steering travel are not required.

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 for more information.

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.

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 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.

TRAXXAS • 29

Failsafe

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

i

ADVANCED TUNING GUIDE

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 model) 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.

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 Link ™ 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 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 Multi-Function 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 to 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 single-flash intervals. 5. Press SET once. The status LED will blink red once repeatedly. 6. Press MENU once. The status LED will blink red twice repeatedly. 7. Press SET. The LED will blink rapidly green. The memory is now locked. Press and hold MENU 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.
