DRIVING YOUR MODEL
Another major factor that affects run time is how the model
is driven. Run times may decrease when the model is driven
repetitively from a stop to top speed and with repetitive hard
acceleration.
Tips for Increasing Run Time
• Use batteries with the highest mAh rating you can purchase.
• Use a high-quality peak-detecting charger.
• Read and follow all maintenance and care instructions provided by
the manufacturer of your batteries and charger.
• Keep the VXL-3s cool. Get plenty of airflow across the ESC heat
sinks.
• Use the correct Low-Voltage Detection setting for your battery (see
page 18). Low-Voltage Detection can be off for maximum NiMH
battery runtime. Never use LiPo batteries while Low-Voltage
Detection is turned off.
• Lower your gear ratio. Installing a smaller pinion or larger spur gear
will lower your gear ratio, causing less power draw from the motor
and battery, and reducing overall operating temperatures.
• Maintain your model. Do not allow dirt or damaged parts to cause
binding in the drivetrain. Keep the motor clean.
mAh Ratings and Power Output
The mAh rating of the battery can affect your top-speed
performance. The higher capacity battery packs experience less
voltage drop under heavy load than low mAh rated packs. The
higher voltage potential allows increased speed until the battery
begins to become discharged.
RUNNING IN WET CONDITIONS
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.
Precautions
• 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. Do not use LiPo batteries 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 16T, or spur
gear as large as 90T) when running in mud, deep puddles, snow,
or other similar situations that will restrict the tires and put much
higher loads on the motor.
