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.
