The VXL-3s has built-in Sensor Motor Backup
Protection to prevent damage if the sensor
leads or phase leads become disconnected.
If a sensor lead becomes damaged or is
disconnected, the VXL-3s automatically
switches to sensorless brushless operation.
The VXL-3s also features Sensor Phase Detection. When a sensored
brushless motor is connected, the VXL-3s will check for proper
wiring. If the motor phase wiring is incorrect, the VXL-3s will not
apply power to the motor until it is wired correctly.

Brushed motors
For the ultimate in versatility, the VXL-3s has no motor limit when
used with a brushed motor. This allows you to use any readily
available 540 or 550 size brushed motors in your VXL-3s equipped
vehicle. Always be sure to follow all break in and maintenance
instructions set forth by the motor manufacturer. The VXL-3s
automatically detects what kind of motor it is connected to so no
programming actions are required to use brushed motors. Simply be
sure to properly connect the motor to the speed control as shown.
Optional brushed motor wiring diagram:
• Motor positive (+) should be connected to phase A (blue).
• Phase B is not used.
• Motor negative (-) should be connected to phase C (white).
If the wiring is reversed, the motor will operate in reverse. If the
motor is wired incorrectly (using phases A+B or B+C), the VXL-3s will
send short pulses to the motor and turn off the LED indicating a fail
safe mode. It will not return to normal operation until wired properly.
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 gauge
An on-board temperature gauge such as the
Traxxas part #4091 can aid you in monitoring
your motor temperature. 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. An optional heat sink
cooling fan can assist in cooling the VXL-3s in
high current motor applications.

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.
Always use the proper length
motor bolts. Using motor
bolts that are too long can
interfere with the motor’s
rotation and damage the
motor’s internals!
