Gearing Compatibility Chart:

The chart below shows recommended
gear combination ranges when using a
NiMH battery pack to power your model.
In the red range, use a battery that has a
continuous rating of at least 70A.

Use NiMH batteries with:

All Models
Only Bandit VXL and Rustler VXL

Only Bandit VXL
Do Not Use NiMH (battery must have
a continuous rating of at least 70A.
Consult with your hobby dealer or
battery manufacturer.)

Gearing

One of the more significant advantages to your model’s transmission
is the extremely wide range of available gear ratios. Changing the
gearing allows you to fine tune the speed of the model and control
the temperatures of the battery pack and motor. Use a lower gear
ratio (numerically larger) to reduce current draw and temperatures.
Use a higher gear (numerically lower) to increase top speed. Use the
following formula to calculate the overall ratio for combinations not
listed on the gear chart:

When using higher gear ratios, it is important to monitor the
temperatures of the battery and motor. If the battery is extremely
hot, and/or the motor is too hot to touch, 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 3500 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
included optional large pinion gear (more teeth).

The included

optional large pinion gear is 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 #6523) 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 an additional
connector to supply power to an optional heat
sink cooling fan (part #3340). The optional heat
sink cooling fan can assist in cooling the VXL-3s
in high current motor applications.
