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.


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 transmitter is not water resistant. Do not subject it to wet conditions such as rain.

• Do not operate your model during a rain storm or other inclement weather where lightning may be present.

• Do not allow your model to come in contact with salt water (ocean water), brackish water (between fresh water and ocean water), or other contaminated water. Salt water is highly conductive and highly corrosive. Use caution if you plan to run your model on or near a beach.

Before Running Your Vehicle in Wet Conditions

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

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

3. Confirm that the receiver box O-ring and cover are installed correctly and secure. Make sure the screws are tight and the blue O-ring is not visibly protruding from the edge of the cover.

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

5. Use lower gearing (smaller pinion gears, as low as 23T or spur gear as large as 55T) when running in mud, deep puddles, snow, or other similar situations that will restrict the tires and put much higher loads on the motor.

Motor Precautions

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

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

• Use special care when operating your model in muddy conditions. Stop operating your model if it appears to be straining due to the tackiness of the mud or build-up of mud on the chassis. Do not allow mud to collect on the motor or pack around the motor.

After Running Your Vehicle in Wet Conditions

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

2. Remove the batteries.

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

4. Blow off the truck with compressed air (optional, but recommended). Wear safety glasses when using compressed air.

5. Remove the wheels from the truck.

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

7. Let the truck stand or you may blow it off with compressed air. Placing the truck in a warm, sunny spot will aid drying. Trapped water and oil will continue to drip from the truck for a few hours. Place it on a towel or piece of cardboard to protect the surface underneath.

8. As a precautionary step, remove the sealed receiver box cover. While unlikely, humidity or tiny amounts of moisture or condensation may enter the receiver box during wet running. This can cause long-term problems with the sensitive electronics in the receiver. Removing the receiver box cover during storage allows the air inside to dry. This step can improve the long-term reliability of the receiver. It is not necessary to remove the receiver or unplug any of the wires.

9. Additional Maintenance: Increase your frequency of disassembly, inspection, and lubrication of the following items. This is necessary after extended wet use or if the vehicle will not be used for an extended period of time (such as a week or longer). This additional maintenance is needed to prevent any trapped moisture from corroding internal steel components. Refer to your exploded view diagrams for help with disassembly and reassembly.

Stub axle housing bearings: Remove, clean, and re-oil the bearings.

Differentials: Remove, disassemble, clean, and re-grease the differential components. Use a light coating of Traxxas high-performance grease (part #5041) on the metal gear teeth.

Rear Drivetrain and Transmission Gears: Remove, disassemble, clean, and re-grease the drivetrain components. Use a light coating of Traxxas high-performance grease (part #5041) on the metal gear teeth. Remove, clean, and re-oil the bearings.

Rear Center Driveshaft: Apply small amounts of high-performance grease (part #5041) at the pin location on each end of the driveshaft. Make sure the driveshaft rotates freely without binding.

Transmission Output Shaft: Apply small amounts of high-performance grease (part #5041) to the rear transmission output shaft for a smooth fit to the bearings. Remove, clean, and re-oil the bearing.

Important Traxxas VXL-4s, VXL-6s and VXL-8s ESC Firmware Update

VXL-6s ESC update

Important VXL-6s ESC Update + How to Update Traxxas ESCs

Maximize your ESC's Potential with the Latest Firmware Updates


The advanced processing capability of the latest generation of Traxxas electronic speed controls, including the VXL-4s, VXL-6s, and VXL-8s, allows for much more than easy operation, smooth power delivery, and real-time telemetry. Unlock the full potential of your model’s speed control with the Traxxas Link Wireless module (#6511) to stay up to date on all the latest features delivered through the Traxxas Link App.
Important Update for VXL-6s Owners
The latest firmware update available via the Traxxas Link App makes a change to the functionality of the EZ-Set button on the VXL-6s speed control found in the E-Revo VXL Brushless and Unlimited Desert Racer.

The EZ-Set button is no longer used to power off the model: to power down your model, simply unplug the battery, or batteries, from the speed control.

Other functionality for the ESC, such as throttle calibration and low voltage detection features, remain the same as previously. Consult your model’s owners manual for additional information.


How to Update Your Traxxas Model

If you have a VXL-4s, VXL-6s, or VXL-8s ESC, it’s easy to update to the latest firmware. You’ll need a #6511 Wireless Module installed in your transmitter. Download the free Traxxas Link app to your phone or tablet and be sure to have fresh batteries in your transmitter, vehicle, and mobile device. Prop up your vehicle so that the wheels are not on the ground and then power on your transmitter and ESC. Launch the Traxxas Link app and select your model using the tile on the menu screen. Once you have green transmitter and vehicle icons in the top corners of the app screen, your transmitter and vehicle are linked. If you are not automatically prompted for an update, click on the Support tile and follow the instructions in the app.
Traxxas Link Home Screen
A banner will appear on the support page with the updates available and instructions to upgrade your ESC. Before starting the upgrade process, ensure your vehicle batteries are charged and have at least 50% power remaining on the transmitter and mobile device. The entire update process may take up to 15 minutes. Click the banner to begin the update. Once the update process begins, you must not terminate the application or power down the transmitter.
Firmware Update Status
Multiple updates may be available. The updates will begin once you click the banner to proceed. All three status LEDs on the ESC will indicate the update progress as well as the progress bar in the Traxxas Link app. Once the update is complete, the ESC may power off.
Firmware Update Status
To complete the process, power the transmitter off and then back on again. This should complete the update process. If you have any questions or require help with this process, please visit us at the shop with your Traxxas Car and Equipment.
