Traxxas HOSS 4x4 VXL 90076-4 Owner's Manual page 28

Always use the proper length
motor bolts. The standard
motor mounting bolts
are 3x8mm. Using motor
bolts that are too long can
interfere with the motor's
rotation and damage the
motor's internal parts!
The VXL-3s features Locked
Rotor Protection. The VXL-3s
checks to make sure the
motor is turning. If the motor
is locked or damaged, the
ESC will enter fail-safe until
the motor is free to rotate.

ADVANCED TUNING ADJUSTMENTS
When using higher gear ratios, it is important to monitor the
temperatures of the battery and motor. If the battery is extremely hot
(150°F) and/or the motor is too hot to touch (200°F), your model is
probably over-geared and drawing too much current. This temperature
test assumes that the model is close to factory stock weight and
operates freely with no excessive friction, dragging, or binding, and the
battery is fully charged and in good condition. Note: Check and adjust
gear mesh if a spur and/or pinion gear is changed.
This model is equipped with a Velineon 540XL 2400Kv motor. The
gear combination that comes stock on each model provides good
overall acceleration and top speed. If you want more top speed,
install the optional large pinion gear (more teeth). Optional large
pinion gears (sold separately) are intended for high-speed running
on hard surfaces, and this gearing is not recommended for off-road
or repetitive starting and stopping.
LIPO BATTERIES
LiPo batteries are intended only for the most advanced users that are
educated on the risks associated with LiPo battery use. It is critical to
follow all instructions supplied by the battery manufacturer and the
charger manufacturer for proper charging, use, and storage of LiPo
batteries. Make sure you understand how to use your LiPo batteries.
See safety precautions and warnings on page 4 for more information.

TEMPERATURES AND COOLING
Monitoring temperatures will extend the lives of the batteries and
motors. There are many options available that will help you monitor
temperatures and cool your components .
Temperature sensor
To accurately monitor motor temperature and
prevent overheating, a telemetry temperature
sensor (part #6521) can be installed on the
motor to continually monitor temperature as
you drive. Generally, try to keep your motor
below 200° F. If necessary, increase airflow to
the motor by cutting out the rear of the body
or windshield.
Heat sink cooling fan
The VXL-3s is equipped with a heat sink cooling
fan (part #3340). The heat sink cooling fan can
assist in cooling the VXL-3s in high current
motor applications.
