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 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 and battery 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

Disconnect the Battery: Always disconnect the battery from the model when not in use.
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 motor can become extremely hot during use, so be careful not to touch it until it is cool. Make sure there is adequate airflow to the motor.
Use the Factory-Installed Connectors: Do not change the battery connector. 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.
Insulate the Wires: Always insulate exposed or damaged wiring with heat shrink tubing to prevent short circuits.
No Reverse Voltage: The speed control is not protected against reverse polarity voltage. When changing the battery, be sure to install the same type of connectors to avoid reverse polarity damage to the speed control. Removing the battery connectors on the speed control or using the same-gender connectors on the speed control will void the product’s warranty.
No Schottky Diodes: External Schottky diodes are
not compatible with reversing speed controls. Using a Schottky diode will damage the ESC and void the 30-day warranty.

Recycling Your NiMH Battery
It is strongly recommended that you recycle the vehicle battery when it has reached the end of its useful life. Do not throw your battery in the trash. To find a recycling center near you, ask your local hobby dealer or visit www.call2recycle.org.

WARNING! CAUTION! DANGER!

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 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.

The status LED does not indicate the charge level of the battery pack installed in the model. Refer to the Troubleshooting section on page 13 for more information on the transmitter status LED codes.
If the status LED doesn’t light green on the
transmitter, check the polarity of the batteries. Check rechargeable batteries for a full charge. If you see any other flashing signal from the LED, refer to the chart on page 13 to identify the code.
Use the Right Batteries
Your transmitter uses AA batteries. New Traxxas alkaline batteries (part

2914) are included with your model. You may also use rechargeable batteries,

such as NiMH (nickel-metal hydride) batteries, in your transmitter. Make sure rechargeable batteries are fully charged according to the manufacturer’s instructions.
If you use rechargeable batteries in your transmitter, be aware that when they begin to lose their charge, they lose power more quickly than regular alkaline batteries.
CAUTION: Discontinue running your model at the first sign of weak batteries (flashing red light) to avoid losing control.

WARNING:
FIRE HAZARD!

Note: Always unplug the battery and remove from the model after use.

THE 2.4GHz RADIO SYSTEM

THE 2.4GHz RADIO SYSTEM
Your model includes a 2.4GHz transmitter. When powered on, the transmitter will automatically locate and lock onto an available frequency, allowing multiple models to be raced together without frequency conflicts. The included 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 11) included
in this manual will help you understand and operate the functions of the radio system. For additional information and how-to videos, visit LaTrax.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.

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 2.4GHz radio system automatically selects and locks onto an open frequency, offering 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.

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

Electronic Speed Control (ESC) – An electronic speed control is the electronic motor control inside the model. ESCs use power more efficiently than mechanical speed controls so that the battery runs longer. An ESC also has circuitry that prevents loss of steering and throttle control as the battery loses its 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.

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.

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 power system is optimized to reduce electrical resistance and the resulting power-robbing heat.

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 ESC 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 2.4GHz radio system, consisting of the receiver, the transmitter, and the servos. The system uses two channels: one to operate the throttle and one to operate the steering.

Voltage – Voltage is a measure of the electrical potential difference between two points, such as between the positive battery terminal and ground. Using the analogy of the garden hose, while current is the quantity of water flow in the hose, voltage corresponds to the pressure that is forcing the water through the hose.

RADIO SYSTEM RULES

The 2.4GHz transmitter has a directional antenna.
For maximum range, hold the transmitter upright and pointed in the direction of the model. Pointing the transmitter away from the model will reduce radio range.
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.
DO NOT CUT any part of the receiver’s antenna wire. Cutting the antenna will reduce range.

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.

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.

USING THE RADIO SYSTEM

The 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 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.
Plug the battery pack connector into the speed control connector.
The on/off switch is integrated into the speed control. Press and release the EZ-Set button to turn the model on. The LED will shine RED (see note, below). To turn the ESC off, press and hold the EZ-Set button until the LED turns off. Note: If the LED shines green, Low-Voltage Detection is activated. This may cause poor performance from the included NiMH battery pack. The default factory setting is for Low-Voltage Detection to be disabled (LED shines red). See page 15 for more information on Low-Voltage Detection.
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.
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.
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.

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.

Higher Speeds Require Greater Distance

The faster you drive your model, the more quickly it will near the limit of radio range. At top speed, this model can cover up to 40 feet per 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 model’s running area, not the far end, so you drive the model toward 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.

RADIO SYSTEM BASIC ADJUSTMENTS

Steering Trim
The steering trim knob located on the face of the transmitter adjusts the neutral (center) pointof 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 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 “ESC Setup Programming” on page 15.

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.

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.

Failsafe
The 2.4GHz 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.

Return the throttle trigger to neutral. The LED will shine RED.
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 shine RED.
To stop, return the throttle trigger to neutral. Note that there is no programmed delay when changing from reverse to forward. Use caution to avoid slamming the speed control from reverse to forward. On high-traction surfaces, this could result in transmission or driveline damage.
To turn the ESC off, press and hold the EZ-Set button until the red LED turns off.
The ESC is equipped with thermal shutdown protection to guard against overheating caused by excessive current flow. If the operating temperature exceeds safe limits, the ESC will automatically shut down. The LED on the face of the ESC will rapidly blink red, even if the throttle trigger is moved back and forth. Once the temperature returns to a safe level, the ESC will once again function normally.

ESC 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.

Elevate the model on a block or a stand so that all the tires are off the ground. This is a precaution to prevent runaway when the speed control in turned on before it is programmed.
Connect a fully charged battery pack to the ESC.
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 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 red, indicating the ESC is on and at neutral (D).

ESC Battery Settings (Low-Voltage Detection Setting) T he ESC is equipped with a built-in Low-Voltage Detection feature that constantly monitors the battery voltage when activated. This feature is not compatible with the NiMH battery supplied with your model. Low-Voltage Detection has been DISABLED for best performance with your battery; however, you should verify that the setting has not been changed before each use.

Verify that Low-Voltage Detection is DISABLED:

Turn on the transmitter (with the throttle at neutral).
Connect a fully charged battery pack to the model.
Press and release the EZ-Set button to turn the ESC on. If the LED is solid red, then the Low-Voltage Detection is DISABLED. If the LED is solid green, then Low-Voltage Detection is ACTIVATED (not safe for use with NiMH batteries).

To disable Low-Voltage Detection (NiMH setting):

Make sure the LED on the ESC is on and GREEN.
Press and hold the EZ-Set button (the LED will turn off). After ten seconds, the motor will beep three times and the LED will shine RED. Release the button.
Low-Voltage Detection is now DISABLED.

LED Codes and Protection Modes

Solid Red: ESC power-on light.
Fast Blinking Red: The ESC is equipped with thermal shutdown protection to guard against overheating caused by excessive current flow. If the operating temperature exceeds safe limits, the ESC will automatically shut down. Let the ESC cool.
Slow Blinking Red (with Low-Voltage Detection on):
The ESC has entered Low-Voltage Protection. When the battery voltage begins to reach the minimum recommended discharge voltage threshold, the ESC will limit the power output to 50% throttle. When the battery voltage attempts to fall below the minimum threshold, the ESC will shut down all motor output. The LED on the speed control will slowly blink red, indicating a low-voltage shutdown. The ESC will stay in this mode until a fully charged battery is connected.
Fast Blinking Green: The ESC’s LED will blink fast green if the speed control is not receiving a signal. Make certain the speed control is properly plugged into the receiver and the transmitter is switched on.
Flashing Red and Green: The ESC has entered Over Voltage Protection. If a battery with too high voltage is used, the ESC will go into a failsafe mode.
Now it’s time to have some fun! This section contains instructions on driving and making adjustments to your model. Before you go on, here are some important precautions to keep in mind.
Allow the model to cool for a few minutes between runs. This is particularly important when using high-capacity battery packs that allow extended periods of running. Monitoring temperatures will extend the lives of the battery 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.
The stock gear combination on each model provides good overall acceleration and top speed. For 25+mph top speeds, install the optional high-speed gearing (parts #7590X, 7591, and 7592, sold separately). The optional high-speed gearing is only intended for high-speed running on hard surfaces, and is not recommended for off-road or repetitive starting and stopping or the motor will be damaged.
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.
Avoid running your model in tall grass, deep sand, or other conditions that severely limit the driving performance of the model. This will strain the power system and could cause early motor failure.
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 bolts 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 2000 mAh battery pack will theoretically run twice as long as a 1000 mAh 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 the included charger or 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 speed control cool.
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.

SHOCK MOUNTING POSITIONS

Your model is equipped with adjustable shocks with variable mounting positions so that you can tune the suspension. It is designed to handle and perform well during off-road driving. If you are going to drive on harder surfaces, move the lower shock to Position 2. The upper shock position can be adjusted and tuned to find the best setup for your driving style.

SHOCK POSITIONS

DRIVING YOUR MODEL

RUNNING IN WET CONDITIONS

Your 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 and other
wet conditions. Though highly water resistant, the model should not be treated as though it is submersible or 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 LaTrax 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. Saltwater 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 driving style in wet conditions to extend the life of the motor (details below).

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.
Confirm that your batteries can be used in wet conditions.

Motor Precautions

Motor life can be greatly reduced in 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 wet motor. Do not submerge the motor under water.

After Running Your Vehicle in Wet Conditions

Remove the battery.
Rinse excess dirt off the model with low-pressure water, such as from a garden hose. DO NOT use a pressure washer or other high-pressure water. Avoid directing water into the transmission, differentials, etc.
Blow off the model with compressed air (optional, but recommended). Wear safety glasses when using compressed air.
Remove the wheels from the model.
Spray all the bearings, bushings, and fasteners with WD-40® or similar water-displacing light oil.
Lubricate the drivetrain with thrust bearing grease (Traxxas Part #2717).
Let the model stand or you may blow off with compressed air. Placing the model in a warm, sunny spot will aid drying. Trapped water will continue to drip from the model for a few hours. Place it on a towel or piece of cardboard to protect the surface underneath.
As a precautionary step, remove the rubber plug from the top of the receiver box and check for trapped water or dampness. 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. If water is present, consider removing the receiver box during storage to allow the air inside to dry. This step can improve the long-term reliability of the receiver. To remove the receiver box, completely loosen the screws on either side of the box, lift the ESC wire out of the groove, and then carefully lift the receiver box and rotate it off to the side. 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 as needed.
- Front and rear differential: Remove, disassemble, clean, and regrease all the gears in the differential (internal gears, ring, and pinion). Refer to your exploded view diagrams for help with disassembly and reassembly.
- Spur and Pinion Gears: Remove, disassemble, and clean these components. No grease is required on the spur and pinion gear. Refer to your exploded view diagrams for help with disassembly and reassembly.
  Motor: Remove the motor, clean with aerosol motor cleaner, and re-oil the bushings with lightweight electric motor oil. Be sure to wear eye protection when using spray aerosol cleaners.

MAINTAINING YOUR MODEL

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 for leaks and proper operation of the shock absorbers.
Check the wiring for any frayed wires or loose connections.
Check the mounting of the receiver and servo and speed control.
Check the tightness of the wheel hex bolts 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.
Inspect the gears for wear, broken teeth, or debris lodged between the teeth.
Check the tightness of all the pivot balls.

Other periodic maintenance:

Motor: Every 10-15 runs, remove and clean the motor by wiping away accumulated dirt and debris from around the motor shaft bushing on the pinion gear side of 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.
Chassis: Keep the chassis clean of accumulated dirt and grime. Periodically inspect the chassis for damage.
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 #7662.
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.
Driveline: Inspect the driveline for signs of wear such as worn drive yokes, dirty axle driveshafts, and any unusual noise or binding. Remove the gear cover, 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.

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

Storage

When you are through running the model for the day, blow it off with compressed air or use a soft-bristled paintbrush 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.
