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 RX box O-ring and cover are installed correctly and secure. Make sure the
screws are tight and the blue O-ring is not visible protruding from the edge of the cover.
4. Confirm that your batteries can be used in wet conditions.
5. Use lower gearing (smaller pinion gears, as low as 9T or spur gear as large as 54T) when
running in mud, deep puddles, snow, or other similar situations that will restrict the
tires and put much higher loads on the motor.
Motor Precautions
• Velineon motor life can be greatly reduced in mud and water. If the motor gets
excessively wet or submerged, use very light throttle (run the motor slowly) until the
excess water can run out. Applying full throttle to a motor full of water can cause rapid
motor failure. Your driving habits will determine motor life with a wet motor. Do not
submerge the motor under water.
• Do not gear the motor by temperature when running in wet conditions. The motor will
be cooled by water contact and will not give an accurate indication of appropriate gearing.
• Use special care when operating your model in muddy conditions. Stop operating your
model if it appears to be straining due to the tackiness of the mud, or build-up of mud
on the chassis. Do not allow mud to collect on the motor or pack around the motor.
After Running Your Vehicle in Wet Conditions
1. Drain the tires by spinning the tires at high speed to “sling” the water out. One way to
do this is to make several high-speed passes on a flat, dry surface, if possible.
2. Remove the batteries.
3. Rinse excess dirt and mud off the truck with low-pressure water, such as from a garden
hose. Do NOT use 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.

Additional Maintenance
: Increase your frequency of disassembly, inspection and
lubrication of the following items: This is necessary after extended wet use or if the
vehicle will not be used for an extended period of time (such as a week or longer). This
additional maintenance is needed to prevent any trapped moisture from corroding
internal steel components.
•
Stub axle housing bearings
: Remove, clean, and re-oil the bearings.
•
Differentials
: Remove, disassemble, clean, and re-grease the differential components.
Use a light coating of wheel bearing grease (from an auto parts store) on the metal
gear teeth. Refer to your exploded view diagrams for help with disassembly and
reassembly.
•
Velineon motor
: After operating your model in wet or muddy conditions, remove
the motor and clean any mud or dirt from the bearings. To access the rear bearing,
remove the plastic cap with thumb pressure, or gently pry the cap off with a flat-
blade screwdriver. To prevent corrosion and assure maximum bearing life, lubricate
the bearings with a light oil (available at your local hobby store). Following these
steps will extend motor life and maintain peak performance. Be sure to wear eye
protection when using spray aerosol cleaners.
RECEIVER BOX: MAINTAINING A WATERTIGHT SEAL
Removing and Installing Radio Gear
The unique design of the receiver box allows the removal and installation of the receiver
without losing the ability to maintain a watertight seal in the box. The patent-pending
wire clamp feature gives you the ability to also install aftermarket radio systems and
maintain the watertight features of the receiver box.
Removing the Receiver
1. Remove the wire clamp by removing the two 2.5x8mm cap screws.
2. Remove the cover by removing the two 3x10mm cap screws.
3. To remove the receiver from the box simply lift it out and set to the side.
The antenna wire is still inside the clamp area and cannot be removed yet.
4. Unplug the servo cables from the receiver and remove
the receiver.
Receiver Installation
1. Install the electronic speed control (ESC), servo, and antenna
wiring through the receiver box top (A).
2. Plug ESC and servo wires into the receiver (see page 10).
3. Bundle wiring as necessary.
4. 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 bottom so that the cover will not pinch it or
damage it in any way.
5. Place receiver box top onto receiver box bottom and
install and tighten the two 3x10mm cap screws securely.
6. Inspect the cover to make sure that the O-ring seal is not
visible.
7. Arrange the wires neatly using the wire guides on the receiver
box top (B). Excess ESC and servo wiring should be bundled
inside the receiver box. Pull out all available antenna wiring
from the receiver box.
8. Apply a small bead of silicone grease to the foam on the
wire clamp (C).
9. Install the wire clamp and tighten the two 2.5x8mm cap screws
securely (D).
