ADJUSTING THE ELECTRONIC SPEED CONTROL
VXL-3s Battery Settings (Low-Voltage Detection Setting)
The Velineon VXL-3s electronic speed control is equipped with
built-in Low-Voltage Detection. The Low-Voltage Detection circuitry
constantly monitors the battery voltage. 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.
The VXL-3s speed control's Low-Voltage Detection has been activated
for best performance with LiPo batteries. The speed control's LED will
glow green when it is turned on, indicating Low-Voltage Detection is
activated.
WARNING: FIRE HAZARD!
Do not use LiPo batteries in this vehicle with
Low-Voltage Detection disabled.
To verify the Low-Voltage Detection setting:
1. Turn on the transmitter (with the throttle at neutral).
2. Connect a fully charged battery pack to the VXL-3s.
3. Press and release the EZ-Set button to turn the VXL-3s on. If the
LED is solid red, then the Low-Voltage Detection is DISABLED (not
safe to use LiPo batteries). If the LED is solid green, then Low-
Voltage Detection is ACTIVATED.
To activate Low-Voltage Detection (LiPo setting):
1. Make sure the LED on the VXL-3s is on and red.
2. Press and hold the EZ-Set button for ten seconds.
The LED will turn off and then light green. Also,
a "rising" musical tone will be emitted from the
motor.
3. Low-Voltage Detection is now ACTIVATED.
To disable Low-Voltage Detection (NiMH setting):
1. Make sure the LED on the VXL-3s is on and green.
2. Press and hold the EZ-Set button for ten seconds.
The LED will turn off and then light red. Also, a
"falling" musical tone will be emitted from the motor.
3. Low-Voltage Detection is now DISABLED.
Transmitter Adjustments for the VXL-3s ESC
Before attempting to program your VXL-3s ESC, it is important to
make sure that your transmitter is properly adjusted (set back to the
factory defaults). Otherwise, you may not get the best performance
from your speed control.
The transmitter should be adjusted as follows:
If the transmitter settings have been adjusted, reset them to the
factory defaults.
1. Turn the transmitter off.
2. Hold both MENU and SET.
3. Turn the transmitter on.
4. Release MENU and SET. The transmitter LED will blink red.
5. Press MENU seven (7) times. The transmitter LED will blink red
eight (8) times repeatedly.
6. Press SET to clear settings. The LED will turn solid green and the
transmitter is restored to default.
VXL-3s Setup Programming (Calibrating your ESC and transmitter)
Read through all of the programming steps before you begin. If you
get lost during programming or receive unexpected results, simply
unplug the battery, wait a few seconds, plug the battery back in, and
start over. If you have questions or need technical assistance, contact
Traxxas at 1-888-TRAXXAS (1-888-872-9927)*.
1. Connect a fully charged battery pack to the VXL-3s.
2. Turn on the transmitter (with the throttle at neutral).
3. Press and hold the EZ-Set button (A). The LED
will first turn green and then red. Release the EZ-Set
button.
4. When the LED blinks RED ONCE, pull the
throttle trigger to the full throttle position
and hold it there (B).
5. When the LED blinks RED TWICE, push the
throttle trigger to the full reverse and hold it
there (C).
6. When the LED blinks GREEN ONCE,
programming is complete. The LED will then shine
green or red (depending on Low-Voltage Detection
setting), indicating the VXL-3s is on and at neutral
(D).
