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 3 for more information.

Advanced VXL-3s Electronic Speed Control Setup

The VXL-3s electronic speed control is capable of controlling

brushed, brushless, and sensored brushless motors. The VXL-3s auto-

detects the motor type and has numerous built-in safeguards to

prevent damage from miswiring or damaged wiring.

Sensorless brushless motors

Sensorless motors are the easiest and most reliable brushless motor

type. The VXL-3s is optimized to deliver the smoothest possible

sensorless motor performance. The Velineon 3500 is a sensorless

brushless motor (see sidebar for specs). The wiring (phase alignment)

of the motor determines its direction of rotation. Refer to the wiring

diagram on page 13.

Sensored brushless motors

The VXL-3s is fully compatible with sensored brushless motors.

Sensor motors use an additional sensor installed in the motor

to communicate rotor position to the speed control. The VXL-3s

features a covered auxiliary port that accepts aftermarket motor

sensors on the front face of the unit.
