wiring diagrams that came with your receiver. On the
VXL-3s, the red wire is positive, the black wire is negative,
and the white wire is the control wire. Warning: On
some older Airtronics
® radio systems, the positive and
negative terminals are opposite of the VXL-3s and an
adapter is required. Crossing the red (+) and black (-)
wires could damage the receiver and the VXL-3s. Study
the manufacturer’s wiring diagrams closely, or consult
your hobby dealer.
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 electronic speed control is factory set with Low-Voltage
Detection activated. Low-Voltage Detection should be
disabled when using NiMH batteries.
Never use LiPo
batteries while Low-Voltage Detection is disabled.
Verify that Low-Voltage Detection is activated:
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 green, then Low-Voltage Detection
is ACTIVATED). If the LED is solid red, then the Low-
Voltage Detection is DISABLED (not safe to use LiPo
batteries).
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.
