• 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° 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 16T 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.
Note: To prevent damage to your vehicle's electronics while
running in soft sand, make these minor modifications to all four
wheel and tire assemblies. Pinch the tire as you cut two small slits
using body scissors. Cut the slits in a "V" pattern; then, remove
the cut material for an approximately 3mm or 1/8" diameter hole.
Repeat on the opposite side of the tire (180˚ apart). Cover the two
breather holes in the wheel with adhesive tape.
Motor Precautions
• 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 battery.
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.
