ADJUSTING THE ELECTRONIC SPEED CONTROL

Patent-Pending 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.

See page 25 for Advanced VXL-3s features.

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. 

• 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 24

). 

• 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 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 is incorrectly set. If the Multi-Function knob is  
set to throttle trim, then adjust the Throttle Trim to the middle  
“0” setting.
