7. To turn the XL-2.5 off, press and hold the EZ-Set button for 1½ seconds or 

until the red LED turns off. 

8. The XL-2.5 is equipped with thermal shutdown protection to guard against 

overheating caused by excessive current flow. If the operating temperature 
exceeds safe limits, the XL-2.5 will automatically shut down. The LED on the 
face of the XL-2.5 will rapidly blink red, even if the throttle trigger is moved 
back and forth. Once the temperature returns to a safe level, the XL-2.5 will 
once again function normally. 

XL-2.5 Profile Selection

The speed control is factory set to Sport Mode (100% forward, brakes, and 
reverse). To disable reverse (Race Mode) or to allow 50% power (patent-
pending Training Mode), follow these steps. The speed control should 
be connected to the receiver and the transmitter 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 XL-2.5 and turn on your 
transmitter.

2. With the XL-2.5 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 XL-2.5 and turn on your 
transmitter.

2. With the XL-2.5 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 XL-2.5 and turn on your 
transmitter.

2. With the XL-2.5 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: 

XL-2.5 power-on light. Low-Voltage Detection is ACTIVATED 

(LiPo setting).

• Solid Red:

 XL-2.5 power-on light. Low-Voltage Detection is DISABLED 

(NiCad/NiMH setting). 

Never use LiPo batteries while Low-Voltage 

Detection is disabled.

• Fast Blinking Red:

 The XL-2.5 is equipped with thermal shutdown protection 

to guard against overheating caused by excessive current flow. If the 
operating temperature exceeds safe limits, the XL-2.5 will automatically shut 
down. Let the XL-2.5 cool. Make sure your model is properly geared for the 
conditions.

• Slow Blinking Red (with Low-Voltage Detection on): 

The XL-2.5 has entered 

Low-Voltage Protection. When the battery voltage begins to reach the 
minimum recommended discharge voltage threshold for LiPo battery packs, 
the XL-2.5 will limit the power output to 50% throttle. When the battery 
voltage attempts to fall below the minimum threshold, the XL-2.5 will shut 
down all motor output. The LED on the speed control will slowly blink red, 
indicating a low-voltage shutdown. The XL-2.5 will stay in this mode until a 
fully charged battery is connected.

• Fast Blinking Green: 

The XL-2.5’s LED will blink fast green if the speed 

control is not receiving a signal. Make certain the speed control is properly 
plugged into the receiver and the transmitter is switched on.

• Flashing Red and Green: 

The XL-2.5 has entered Over Voltage Protection. If a 

battery with too high voltage (3S LiPo) is used, the XL-2.5 will go into a failsafe 
mode. The XL-2.5 is only compatible with 2S LiPo.

ADJUSTING THE ELECTRONIC SPEED CONTROL

*Patent-pending

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 ESC is set to Profile 1 
(Sport Mode) as the default.  
To quickly change to Profile 3 
(Training Mode), with the 
transmitter on and the ESC 
turned off, press and hold 
the SET button until the light 
blinks red three times and then 
release. For full power, turn off 
the ESC then 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.
