ADJUSTING THE ELECTRONIC SPEED CONTROL
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 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
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.
VXL-3s Profile Selection
The speed control is factory set to Profile #1 (100% forward, brakes, and reverse).
To disable reverse (Profile #2) or to allow 50% forward and 50% reverse (Profile #3),
follow the steps below. The speed control should be connected to the receiver
and battery, and the transmitter should be adjusted as described previously. The
profiles are selected by entering the programming mode.
Profile Description
Profile #1 (Sport Mode): 100% Forward, 100% Brakes, 100% Reverse
Profile #2 (Race Mode): 100% Forward, 100% Brakes, No Reverse
Profile #3 (Training Mode): 50% Forward, 100% Brakes, 50% Reverse
Selecting Sport Mode
(Profile #1: 100% Forward, 100% Brakes, 100% 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 once, 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.
Selecting Race Mode
(Profile #2: 100% Forward, 100% Brakes, No 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 twice, 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.
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).
Never use LiPo batteries 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 26).
• 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 33) is incorrectly set. If the Multi-Function
knob is set to throttle trim, then adjust the Throttle Trim to the
middle “0” setting.
