TRAXXAS RALLY • 17

ADJUSTING THE ELECTRONIC SPEED CONTROL

Patented 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.

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. 

• 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. 

• 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 23). 

• Very Fast Blinking Red

: Thermal Shutdown Protection and Low 

Voltage Protection (see above) have occurred at the same time.

• 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 (see page 26) is incorrectly set. If the Multi-Function 
knob is set to throttle trim, then adjust the Throttle Trim to the 
middle “0” setting.
