Patented Training Mode
(Profile #3) reduces forward
and reverse throttle by 50%.
Training Mode is provided
to reduce the power output,
allowing beginning drivers
to better control the model.
As driving skills improve,
simply change to Sport or
Race Mode for full-power
operation.
Tip For Fast Mode Changes
The VXL-3s is set to Profile 1
(Sport Mode) as the default.
To quickly change to Profile 3
(Training Mode), with the
transmitter on, press and
hold the EZ-Set button until
the light blinks red three
times and then release.
For full power, quickly change
back to Profile 1 (Sport Mode)
by pressing and holding the
EZ-Set button until the light
blinks red one time and
then releasing.
The VXL-3s has built-in
programming that prevents
accidental activation of
reverse while in forward
motion and vice-versa. You
must come to a complete
stop, release the throttle
trigger, then apply opposite
throttle to engage the motor
in the desired direction.

ADJUSTING THE ELECTRONIC SPEED CONTROL
Selecting Training Mode
(Profile #3: 50% Forward, 100% Brakes, 50% Reverse)
1. Connect a fully charged battery pack to
the VXL-3s and turn on your transmitter.
2. With the VXL-3s off, press and hold the
EZ-Set button until the LED turns solid
green, then solid red and then begins
blinking red (indicating the Profile
numbers).
3. When the LED blinks red three times,
release the EZ-Set button.
4. The LED will blink and then turn solid green (Low-Voltage Detection
ACTIVE) or red (Low-Voltage Detection DISABLED). The model is
ready to drive.
Note: If you missed the mode you wanted, keep the EZ-Set button
pressed down and the blink cycle will repeat until the button is
released and a Mode is selected.
LED Codes and Protection Modes
• Solid Green: VXL-3s power-on light. Low-Voltage Detection is
ACTIVATED (LiPo setting).
• Solid Red: VXL-3s power-on light. Low-Voltage Detection is
DISABLED (NiCad/NiMH setting).
while Low-Voltage Detection is disabled.
• Slow Blinking Red (with Low-Voltage Detection on): The
VXL-3s has entered Low-Voltage Protection. When the
battery voltage begins to reach the minimum recommended
discharge voltage threshold for LiPo battery packs, the VXL-3s
will limit the power output to 50% throttle. When the battery
voltage attempts to fall below the minimum threshold, the
VXL-3s will shut down all motor output. The LED on the
speed control will slowly blink red, indicating a low-voltage
shutdown. The VXL-3s will stay in this mode until a fully
charged battery is connected.

• Fast Blinking Red: Thermal Shutdown Protection Stage 1.
If the motor has lower than normal power and the VXL-3s
is hot, the VXL-3s has entered Stage 1 Thermal Shutdown
Protection to guard against overheating caused by excessive
current flow. If the motor has no power and the VXL-3s is
very hot, the VXL-3s has entered Stage 2 Thermal Shutdown
Protection and has automatically shut down. Let the VXL-
3s cool. Make sure your model is properly geared for the
conditions (see page 27).
• Very Fast Blinking Red: Thermal Shutdown Protection and
Low Voltage Protection (see above) have occurred at the
same time.
• Alternating; Blinks Red then Green: If the motor has no
power, the VXL-3s has entered Over Voltage Protection. If
a battery with too high voltage is used, the VXL-3s will go
into a fail-safe mode. WARNING: If input voltage exceeds
approximately 20-volts, the ESC may be damaged. Do not
exceed 12.6 maximum peak input voltage.
• Blinking Green: The VXL-3s is indicating the transmitter
Throttle Trim (see page 31) is incorrectly set. If the Multi-
Function knob is set to throttle trim, then adjust the Throttle
Trim to the middle "0" setting.
