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). This will only work with
holes cut in the tires, see step 2 of Before Running Your Vehicle in
Wet Conditions.
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
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.
• 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.
