18 • STAMPEDE 4X4
• 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
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 centerline, 180° 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.
Motor Precautions
• Titan 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
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,
transmission, 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 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.
•
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.
•
Titan motor
: Remove the motor, clean with aerosol motor
cleaner, and re-oil the bushings with lightweight motor oil. Be
sure to wear eye protection when using spray aerosol cleaners.
