ADJUSTING THE ELECTRONIC SPEED CONTROL
Electronic Speed Control Adjustments
The VXL-4s electronic speed control's default settings were programmed
at the factory and should not require adjustment for normal operation.
The following information is helpful to confirm the settings or allow you to
customize the settings for your needs.
ATTENTION: USING LiPo BATTERIES
The VXL-4s electronic speed control is designed to operate on 3s or 4s
LiPo battery power. When you turn your model on, the speed control's status
LED is green, indicating that Low Voltage Detection is activated to prevent
over-discharging of LiPo batteries. LiPo batteries are intended only for the
most advanced users that are educated on the risks associated with LiPo
battery use.
WARNING: FIRE HAZARD!
Do not use LiPo batteries in this vehicle with Low-Voltage
Detection disabled.
DO NOT use Nickel Metal Hydride
(NiMH) batteries with this model. The
batteries will become extremely hot
and damage or injury could occur.
Selecting a Throttle Mode: SPORT, RACE, or TRAINING
1. Connect a fully charged battery pack to the VXL-4s and turn on your
transmitter.
2. Press and hold the EZ-Set button until the LED turns solid green, then
solid red and then begins blinking red. It will blink once, then twice, then
three times, then repeat.
One blink = Sport Mode is the default setting. It allows full forward and
reverse throttle.
Two blinks = Race Mode removes reverse throttle in case your track does
not allow it.
Three blinks = Training Mode will slow the model down by 50% to make
it easier for new drivers to control the model.
3. Release the EZ-Set button after the number of blinks for the mode you
wish to select. Note: If you missed the mode you wanted, keep the EZ-Set
button pressed down and the blink cycle will repeat.
4. The LED will blink and then turn solid green (Low-Voltage Detection
ACTIVE). The model is ready to drive in the mode you have selected.
VXL-4s Setup Programming (calibrating the speed control and transmitter)
The speed control is calibrated at the factory. If the LED on the speed control
is flashing green, then follow these steps to recalibrate it (set the throttle to
the neutral position).
1. Connect a fully charged battery pack to the VXL-4s.
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.
VXL-4s 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.
