ADJUSTING THE ELECTRONIC SPEED CONTROL

Patent-Pending Training

Mode (Prole #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 Prole 1

(Sport Mode) as the default.

To quickly change to Prole 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 Prole 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 Prole Selection

The speed control is factory set to Prole #1 (100% forward, brakes, and

reverse). To disable reverse (Prole #2) or to allow 50% forward and 50%

reverse (Prole #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 proles are selected by entering the

programming mode.

Prole Description

Prole #1 (Sport Mode): 100% Forward, 100% Brakes, 100% Reverse

Prole #2 (Race Mode): 100% Forward, 100% Brakes, No Reverse

Prole #3 (Training Mode): 50% Forward, 100% Brakes, 50% Reverse

Selecting Sport Mode (Prole #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

Prole 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 ON) or red (Low-Voltage Detection OFF). The model

is ready to drive.

Selecting Race Mode (Prole #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

Prole 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 ON) or red (Low-Voltage Detection OFF). The model

is ready to drive.

Selecting Training Mode (Prole #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 Prole 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 ON) or red (Low-

Voltage Detection OFF). 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 ON

(LiPo setting).

• Solid Red: VXL-3s power-on light. Low-Voltage Detection is OFF

(NiCad/NiMH setting).

• 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 ow. 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).

• 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.

• 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 failsafe 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 16) is incorrectly set. Adjust the Throttle Trim to the

middle “0” setting.
