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: Switch on your transmitter first before switching on the speed control to prevent runaways and erratic performance.
Don’t Get Burned: The ESC and motor can become extremely hot during use, so be careful not to touch them until they cool. Supply adequate airflow for cooling.
Use 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.
No Schottky Diodes: External Schottky diodes are not compatible with reversing speed controls. Using a Schottky diode with your Traxxas speed control will damage the ESC and void the 30-day warranty.
Always adhere to the minimum and maximum limitations of the speed control as stated in the specifications table in the Owner’s Manual.

FIRE HAZARD! 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 18 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:

Your model is able to use 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 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 Traxxas iD charger to charge Traxxas iD batteries. ONLY use a Lithium Polymer (LiPo) balance charger with a balanced adapter port to charge LiPo batteries. Never use NiMH or NiCad-type chargers or charge modes to charge LiPo batteries. DO NOT charge LiPo batteries with a NiMH-only charger. The use of a NiMH or NiCad charger or charge mode will damage LiPo batteries and may cause fire, personal injury, and/or property damage.
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.

TRAXXAS TQ 2.4GHz RADIO SYSTEM

Applying the Decals

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

To apply the decals, place one end down, hold the other end up, and gradually smooth the decal down with your finger as you go. This will prevent air bubbles. Placing both ends of the decal down and then trying to smooth it out will result in air pockets. Look at the photos on the box for typical decal placement.

INTRODUCTION

Your model includes the TQ 2.4GHz transmitter. When powered on, the TQ 2.4GHz will automatically locate and lock onto an available frequency, allowing multiple models to be raced together without frequency conflicts. Just switch on and drive! The included TQ 2.4GHz radio system has been programmed for your model
at the factory and does not require adjustment, but it does have settings you may need to access to maintain proper operation of your model. The detailed instructions (page 16) included in this manual will help you understand and operate the functions of the new TQ 2.4GHz 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.
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 BL-2s 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 BL-2s 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 BL-2s 3300 motor is a 3300 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 shorten run times.
NiMH – Abbreviation for nickel-metal hydride. Rechargeable NiMH batteries offer high current handling and much greater resistance to the “memory” effect. NiMH batteries generally allow higher capacity than NiCad batteries. They can last up to 500 charge cycles. A peak charger designed for NiMH batteries is required for optimal performance.
Receiver – The radio unit inside your model that receives signals from the transmitter and relays them to the servos.
an object resists or obstructs the flow of current through it. When flow is constricted, energy is converted to heat and is lost. The Velineon power system is optimized to reduce electrical resistance and the resulting power- robbing heat.
Rotor – The rotor is the main shaft of the brushless motor. In a brushless motor, the magnets are mounted to the rotor, and the electromagnetic windings are built into the motor housing.
Sensored – Sensored refers to a type of brushless motor that uses an internal sensor in the motor to communicate rotor position information back to the electronic speed control.
Sensorless – Sensorless refers to a brushless motor that uses advanced instructions from an electronic speed control to provide smooth operation. Additional motor sensors and wiring are not required. The BL-2s electronic speed control is optimized for smooth sensorless control.
Servo – Small motor unit in your model that operates the steering mechanism.
Transmitter – The hand-held radio unit that sends throttle and steering instructions to your model.
Trim – The fine-tuning adjustment of the neutral position of the servos, made by adjusting the steering trim knob on the face of the transmitter.
Thermal Shutdown Protection – Temperature sensing electronics used in the electronic speed control to 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 TQ 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.
2.4GHz Spread Spectrum – This model is equipped with the latest RC technology. Unlike AM and FM systems that require frequency crystals and are prone to frequency conflicts, the TQ 2.4GHz system automatically selects and locks onto an open frequency, and offers superior resistance to interference and “glitching.”
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 antenna wire. Kinks in the antenna wire will reduce range.
DO NOT CUT any part of the receiver 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.
The antenna wire must be installed into the antenna tube to protect it from getting cut or damaged, which will reduce range. When installing the antenna wire into the antenna tube, be careful not to kink the wire by pressing it against the antenna tube cap. The antenna wire should extend to just below or to within one-half inch below the cap.

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.

BL-2s Wiring Diagram

Your model is equipped with the Traxxas TQ 2.4GHz transmitter. The transmitter has two channels: Channel one operates the steering, and channel two operates the throttle. The receiver inside the model has three output channels. Your model is equipped with one servo and an electronic speed control.

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

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

INSTALLING THE BATTERY PACK

Install the battery pack with the battery wires facing the rear of the model. Insert the tabs of the battery hold-down into the slots in the rear hold-down retainer and then place the battery hold-down over the post. Secure the battery hold-down with body clip in the hole in the post. Do not connect the battery pack yet.

$TRAXXAS-104354-74-Slash-Mudboss- $21$$
Using a Different Battery Configuration
The battery hold-down can be flipped to accommodate different height battery packs. Note: For taller batteries, an extended battery hold-down, part #5827X, is available (sold separately). For shorter batteries (6-cell), use the included foam block in the front of the battery compartment.

The Traxxas High-Current Connector

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

SETTING UP THE ANTENNA

The receiver antenna and antenna tube must be properly installed before operating your model. Follow these steps to install the antenna and antenna tube:

Slide the antenna wire into the antenna tube to its full extent. When fully inserted, the wire should reach to approximately 1/2 inch below the tube cap. Do not leave any slack in the antenna wire.
Insert the base of the antenna tube into the antenna post. Take care not to crimp the antenna wire.
Slide the crimp nut over the antenna tube and screw it onto the antenna post.
Use the supplied tool to tighten the crimp nut on the post just until the antenna tube is securely in place. Do not overtighten or crush the antenna wire against the chassis. Do not bend or kink the antenna wire! Do not shorten the antenna tube. See the sidebar for more information.

Make certain the model’s receiver antenna is properly installed before operating your model. Failure to properly install the receiver antenna will result in greatly reduced radio range and potential loss of control.
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.
Remember, always turn the transmitter on first and off last to avoid damage to your model.
When rechargeable batteries begin to lose their charge, they will fade much faster than alkaline dry cells. 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.

RADIO SYSTEM CONTROLS

RADIO SYSTEM RULES

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 Failsafes to prevent this type of malfunction, but the first, best defense against a runaway model is to always turn the transmitter on first and off last.
Always use new or freshly charged 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 steering trim knob located on the face of the transmitter adjusts the neutral (center) point of the steering channel. If your model pulls to the right or left when the steering wheel is centered, turn the knob until the model drives straight when the steering wheel is centered.

Channel Reversing
The TQ 2.4GHz transmitter has been programmed with the correct servo direction settings for your model and should not require adjustment. These instructions are for reference and troubleshooting only.

Reversing a channel reverses the direction of the corresponding servo. For example, if you turn the steering wheel to the right and the model turns left, Channel 1 would need to be reversed to correct the servo direction. Use the following procedures to reverse the steering and throttle channels, if necessary. Servo reversing should only be required if you accidentally reset the direction of a channel. Do not reverse the steering or throttle channels unless necessary.

Steering reversing procedure:

Press and hold the SET button on the transmitter for two seconds. The status LED will flash green.
Turn and hold the steering wheel to the full left or full right position (it does not matter which position you choose).
While holding the steering wheel in position, press the SET button to reverse the channel.
The channel is now reversed. Confirm correct servo operation before running your model.

Throttle reversing procedure:
Note : Throttle reversing is often times unnecessary on electric models, as issues with the throttle can usually be solved by reprogramming the speed control and/or verifying that the motor is wired correctly. Before attempting to reverse the throttle channel using the procedure below, you should first recalibrate the speed control. Refer to “BL-2s Setup Programming” on page 19.

Press and hold the SET button on the transmitter for two seconds.
- The status LED will flash green.
Move and hold the throttle trigger to the full forward or full brake position (it does not matter which position you choose).
While holding the throttle trigger in position, press the SET button to reverse the channel.
The channel is now reversed. Recalibrate the speed control and then confirm correct servo operation before running your model.

USING THE RADIO SYSTEM
The TQ 2.4GHz Radio System has been adjusted at the factory for correct operation with your model. The adjustment should be checked before running the model, in case of movement during shipping. Here’s how:

Turn the transmitter switch on. The status LED on the transmitter should be solid green (not flashing).
Elevate the model so that the rear tires are off the ground.
- If you are holding the model, grip it firmly. Make sure your hands are clear of the moving parts of the model.
Plug the battery pack in the model into the speed control.
Press and release the EZ-Set button on the speed control to turn the model on. The speed control’s LED will glow red. To turn the speed control off, press the EZ-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. Never use LiPo batteries while Low-Voltage Detection is turned off. for more information.
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.
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, slowly adjust the steering trim control on the transmitter until they are pointing straight ahead.
Operate the throttle trigger to ensure that you have full forward and reverse operation and that the motor stops when the throttle trigger is at neutral.
Once adjustments are made, turn off 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.

Turn on the radio system and check its operation as described in the previous section.
Have a friend hold the model. Make sure hands and clothing are clear of the wheels and other moving parts on the model.
Walk away from the model with the transmitter until you reach the farthest distance you plan to operate the model.
Operate the controls on the transmitter once again to be sure that the model responds correctly.
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. Using Reverse: While driving, push the throttle trigger forward to apply brakes. Once stopped, return the throttle trigger to neutral. Push the throttle trigger forward again to engage proportional reverse.

The TQ 2.4GHz transmitter has a directional antenna. For maximum range, hold the transmitter upright and point in the direction of the model. Pointing the transmitter away from the model will reduce radio range.

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 when the Failsafe mode is activated. If Failsafe activates while you are operating your model, determine the reason for signal loss and resolve the problem before operating your model again.

Higher Speeds Require Greater Distance
The faster you drive your model, the more quickly it will near the limit of radio range. At top speeds, models can cover anywhere between 25 to 100 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. Your model’s radio system is designed to operate reliably up to the approximate distance that it is no longer easy or comfortable to see and control the model. Most drivers will struggle to see and drive their model at distances farther than a football field (300+ feet). At greater distances, you could lose sight of your model and you may also exceed the radio system’s operating range which will cause the Failsafe system to activate. For best visibility and control of your model keep your model within 200 feet, regardless of the maximum
range available.

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.

TQ 2.4GHz Binding Instructions
For proper operation, the transmitter and receiver must be electronically ‘bound.’ This has been done for you at the factory. Should you ever need to re-bind the system or bind to an additional transmitter or receiver, follow these instructions. Note: the receiver must be connected to a 4.8-6.0v (nominal) power source for binding and the transmitter and receiver must be within 5 feet of each other.

Press and hold the SET button on the transmitter.
Turn on the transmitter and release the SET button. The status LED will flash red slowly, indicating that the transmitter is in bind mode.
Press and hold the LINK button on the receiver.
Turn on the speed control by pressing the EZ-Set button and release the LINK button.
When the LEDs on both the transmitter and the receiver turn solid green, the system is bound and ready for use. Confirm that the steering and throttle operate properly before driving your model.

BL-2s™ Battery Settings (Low-Voltage Detection Setting)
The BL-2s 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 BL-2s will limit the power output to 50% throttle. When the battery voltage attempts to fall below the minimum threshold, the BL-2s will shut down all motor output. The LED on the speed control will slowly blink red, indicating a low-voltage shutdown. The BL-2s will stay in this mode until a fully charged battery is connected.

When you turn your model on, the BL-2s speed control’s status LED will glow green, indicating that Low-Voltage Detection is activated to prevent over- discharging of LiPo batteries. LiPo batteries are intended only for the most advanced users that are educated on the risks associated with LiPo battery use.

WARNING: FIRE HAZARD!
Do not use LiPo batteries in this vehicle with Low-Voltage Detection disabled.

To verify the Low-Voltage Detection setting:

Turn on the transmitter (with the throttle at neutral).
Connect a fully charged battery pack to the BL-2s.
Press and release the EZ-Set button to turn the BL-2s 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):

Make sure the LED on the BL-2s is on and red.
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.
Low-Voltage Detection is now ACTIVATED.

To disable Low-Voltage Detection (NiMH setting):

Make sure the LED on the BL-2s is on and green.
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.
Low-Voltage Detection is now DISABLED.

Transmitter Adjustments for the BL-2s ESC
Before attempting to program your BL-2s 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 settings have been adjusted, reset them to the factory defaults.

Turn the transmitter off.
Hold both MENU and SET.
Turn the transmitter on.
Release MENU and SET. The transmitter LED will blink red.
Press SET to clear settings. The LED will turn solid green and the transmitter is restored to default.

BL-2s 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.

Connect a fully charged battery pack to the BL-2s.
Turn on the transmitter (with the throttle at neutral).
Press and hold the EZ-Set button (A). The LED will first turn green and then red. Release the EZ-Set button.
When the LED blinks RED ONCE, pull the throttle trigger to the full throttle position and hold it there (B).
When the LED blinks RED TWICE, push the throttle trigger to the full reverse and hold it there (C).
When the LED blinks GREEN ONCE, programming is complete. The LED will then shine green or red (depending on Low-Voltage Detection setting), indicating the BL-2s is on and at neutral (D).

BL-2s Operation
To operate the speed control and test programming, place the vehicle on a stable block or stand so that all of the drive wheels are off the ground. Disconnect the motor wires (see page 12). This will ensure 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 ACTIVATED (factory default) and the LED shines green. If Low-Voltage Detection is DISABLED, the LED will shine red instead of green in steps 1-7 below. Never use LiPo batteries while Low-Voltage
Detection is disabled.

With the transmitter on, press and release the EZ-Set button. The LED will shine green. This turns the BL-2s on.
Apply forward throttle. The LED will turn off until full throttle power is reached. At full throttle, the LED will illuminate green.
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 green.
Return the throttle trigger to neutral. The LED will shine green.
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 green.
To stop, return the throttle trigger to neutral. Note that there is a programmed delay when changing from reverse to forward. This prevents damage to the transmission on high-traction surfaces.
To turn the BL-2s off, press the EZ-Set bu button until the LED turns off (.5 seconds).

• Solid Green: BL-2s power-on light. Low-Voltage Detection is ACTIVATED (LiPo setting).
• Solid Red: BL-2s 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 BL-2s has entered Low-Voltage Protection. When the battery voltage begins to reach the minimum recommended discharge voltage threshold for LiPo battery packs, the BL-2s will limit the power output to 50% throttle. When the battery voltage attempts to fall below the minimum threshold, the BL-2s will shut down all motor output. The LED on the speed control will slowly blink red, indicating a low-voltage shutdown. The BL-2s 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 BL-2s is hot, the BL-2s has entered Stage 1 Thermal Shutdown Protection to guard against overheating caused by excessive current flow. If the motor has no power and the BL-2s is very hot, the BL-2s has entered Stage 2 Thermal Shutdown Protection and has automatically shut down. Let the BL-2s cool. Make sure your model is properly geared for the conditions .
• Very Fast Blinking Red: Thermal Shutdown Protection and LowVoltage Protection (see above) have occurred at the same time.
• Alternating; Blinks Red then Green: If the motor has no power, the BL-2s has entered Over Voltage Protection. If a battery with too high voltage is used, the BL-2s 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 BL-2s is indicating the transmitter Throttle Trim is incorrectly set. 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 (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.
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 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 and charger.
Keep the BL-2s cool. Get plenty of airflow across the ESC heat sinks.
Use the correct Low-Voltage Detection setting for your battery (see page 19). 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.
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 TQ 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

Consult the section “After Running Your Vehicle in Wet Conditions” before proceeding. Make sure you understand the additional maintenance required with wet running.
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° apart.
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.
Confirm that your batteries can be used in wet conditions.

Motor Precautions

Motor life can be greatly reduced in mud and water. If the motor gets excessively wet or submerged, use very light throttle (run the motor slowly) until the excess water can run out. Applying full throttle to a motor full of water can cause rapid motor failure. Your driving habits will determine motor life with a wet motor. Do not submerge the motor under water.
Do not gear the motor by temperature when running in wet conditions. The motor will be cooled by water contact and will not give an accurate indication of appropriate gearing.

After Running Your Vehicle in Wet Conditions

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.
Remove the batteries.
Rinse excess dirt and mud off the truck 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.
Blow off the truck with compressed air (optional, but recommended). Wear safety glasses when using compressed air.
Remove the wheels from the truck.
Spray all the bearings, drivetrain, and fasteners with WD-40® or similar water displacing light oil.
Let the truck stand or you may blow 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.
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.
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.
- Spur and pinion gears: Inspect the gears for wear, broken teeth, or any debris lodged between the teeth. You do not need to lubricate the gears.
- Motor: Remove the motor, clean with aerosol motor cleaner, and re-oil the bearings with lightweight motor oil. 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

To remove the cover, remove the two 3x8mm button-head cap screws.
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.
Remove the wire clamp by removing the two 2.5x8mm cap screws.
4. Unplug the servo cables from the receiver and remove the receiver.

Receiver Installation

Always install the wires into the receiver box before installing the receiver.
Install the antenna wire and the servo cables into the receiver box.
Arrange the wires neatly using the wire guides in the receiver box (A). The excess wire will be bundled inside the receiver box. Label which wire is for which channel.
Apply a small bead of silicone grease (Traxxas part #1647) to the wire clamp (B).
Install the wire clamp and tighten the two 2.5x8mm cap screws securely.
Install the receiver into the box and plug the wires into the receiver (C). Refer to page 12 for the wiring diagram.
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.
Install the cover and tighten the two 3x8mm button-head cap screws securely.
Inspect the cover to make sure that the O-ring seal is not visible.

ADJUSTING YOUR MODEL

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.

To achieve a good starting point for the slipper clutch, 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 counter- clockwise one full turn.

Once you become familiar with driving your model, you might need to make adjustments for better driving performance
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 Tighten power sent to the rear wheels to prevent tire spin. When it slips, the slipper clutch makes a high- pitch, whining noise. Remove the loosened rubber slipper clutch plug on the
transmission cover in order to adjust the slipper. Use the 4-way wrench to turn the adjusting nut clockwise to tighten and counterclockwise to loosen. Place the model on a high-traction surface, such as carpet. Adjust the slipper so that you can hear it slip for approximately two feet from a standing, full- throttle start. (Learn more about adjusting the slipper clutch in the sidebar.)

Motor and Gearing
One of the more significant advantages of 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 modified motor should be geared lower (higher numerically) than a stock motor because it will reach its maximum power at higher rpms. A modified 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 x 2.72 = Final Gear Ratio

Pinion Gear Teeth

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 BL-2s 3300kV 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 high-speed gearing (more teeth) or if you want more acceleration and less top speed, use a smaller pinion gear (optional gearing not included).

The BL-2s 3300kV is equipped with an integrated cooling fan that is effective during medium to high-speed operation. The gearbox is specially vented to cool the motor. Repetitive starting and stopping over short distances creates excess heat and will not allow the fan to cool the motor properly. For this type of driving, smaller pinion gears are recommended to reduce load on the motor. Gearing Compatibility Chart (see sidebar)

The chart in the sidebar shows a full range of gear combinations. This does NOT imply that these gear combinations should be used. Over-gearing (bigger pinions, smaller spurs) can overheat and damage the motor and/or speed control. Items in black will fit 540 motor only (not Titan 12T).
Adjusting Gear Mesh
Incorrect gear mesh is the most common cause of stripped spur gears. Gear mesh should be checked and adjusted anytime a gear is replaced. To set the gear mesh, cut a narrow strip of notebook paper and run it into the gear mesh. Loosen the motor screws and slide the motor and pinion gear into the spur gear. Retighten the motor screws and then remove the strip of paper. You should be able to run a fresh strip of paper through the gears without binding them.

Adjusting the Toe-in
Geometry and alignment specs play an important roll in your 0°model’s handling. Take the time to set them correctly. 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 Toe-in toe-in). This will ensure the same amount of steering in both directions. For increased stability add 1°-2° of toe-in to each front wheel. Use the turnbuckles to adjust the alignment.
Adjusting the Camber
The camber angle of both the front and rear wheels can be adjusted with the camber rods (upper turnbuckles). Use a square or right-angle triangle to set the camber accurately. The stock camber of the front wheels is -1° of camber. In the rear, the stock camber is -1.5°. These adjustments should be set with the truck positioned at its normal ride height with a battery installed. 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 light weight 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). The thinner viscosity oils (30W or less) flow more smoothly and are more consistent, while thicker oils provide more damping. From the factory, the shocks are filled with SAE-50W silicone oil. Use only 100% pure silicone shock oil to prolong seal life. 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 setup 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. 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 driving on a prepared track (position 2 on the front suspension arms and position 3 on the rear suspension arms). If you plan on driving off-road, the following changes should be made:

Move the front shocks to the innermost position (1) on the suspension arms.
Move the rear shocks to the position 2 on the suspension arms.

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.

Remove the servo horn from the steering servo.
Connect the steering servo to channel 1 on the receiver. Connect the electronic speed control (ESC) to channel 2.
Place fresh “AA” batteries in the transmitter and turn the transmitter power switch on.
Turn the transmitter’s steering trim knob to the center “0” position.
Disconnect the motor wires (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 19). The servo’s output shaft will automatically jump to its center position.
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.
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. Repeat 1-6 if necessary.

MAINTAINING YOUR MODEL

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

Your model requires timely maintenance in order to stay in top running condition. The following procedures should be taken very seriously.

Inspect the vehicle for obvious damage or wear. Look for:

Cracked, bent, or damaged parts
Check the wheels and steering for binding.
Check the operation of the shock absorbers.
Check the wiring for any frayed wires or loose connections.
Check the mounting of the receiver and servo(s) and speed control.
Check the tightness of the wheel nuts with a wrench.
Check the operation of the radio system, especially the condition of the batteries.
Check for any loose screws in the chassis structure or suspension.
The steering servo saver will wear out over time. If the steering becomes loose, the servo saver should be replaced.
Inspect the gears for wear, broken teeth, or debris lodged between the teeth.
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.
Steering: Over time, you may notice increased looseness in the steering system. There are several components that will wear out from use: the servo saver (Traxxas part #3744), the bellcrank bushings (Traxxas part #2545), and the tie rod ends (Traxxas part #2742). Replace these components as needed to restore factory tolerances.
Motor: Every 10-15 runs, remove, clean, and lubricate the motor. Use a product such as electric motor cleaning spray to flush dirt out of the motor. After cleaning, lubricate the bushings at each end of the motor with a drop of light-weight electric motor oil.
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 kits for two shocks is part #5462 (front) or #7463 (rear).
Suspension: Periodically inspect the model for signs of damage such as bent or dirty suspension pins, bent turnbuckles, loose screws, and any signs of stress or bending. Replace components as needed.
Driveline: Inspect the driveline for signs of wear such as worn drive yokes, dirty axle half shafts, and any unusual noise or binding. If a U-joint pops apart, then it is time to replace the part. Remove the gear cover and inspect the spur gear for wear. 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, then also remove the batteries from the transmitter.
