ADJUSTING THE ELECTRONIC SPEED CONTROL
Throttle Neutral Protection
The XL-5 HV speed control
features Throttle Neutral
Protection, which prevents
the model from suddenly
accelerating if the speed
control is switched on while
the transmitter’s trigger is
being held. When the trigger is
returned to neutral, the XL-5 HV
will operate properly.
Selecting Trail Mode
(Profile #4: 100% Forward, 100% Brakes, 100% Reverse;
Drag Brake at Neutral)
1. Connect a fully charged battery pack
to the XL-5 HV and turn on your
transmitter.
2. With the XL-5 HV 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 FOUR 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.
Selecting Crawl Mode
(Profile #5: 100% Forward, Hill Hold Brakes at Neutral, Immediate
Reverse)
1. Connect a fully charged battery pack
to the XL-5 HV and turn on your
transmitter.
2. With the XL-5 HV 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 FIVE 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-5 HV power-on light. Low-
Voltage Detection is ACTIVATED (LiPo setting).
• Solid Red: XL-5 HV power-on light. Low-Voltage
Detection is DISABLED (NiMH setting).
• Fast Blinking Red: Overtemp. The XL-5 HV is
equipped with thermal shutdown protection to
guard against overheating caused by excessive
current flow. If the operating temperature exceeds
safe limits, the XL-5 HV will automatically shut down. Let the XL-5
HV cool before continuing. The ESC can get too hot in situations
such as climbing and crawling in high gear, which increases load
on the system. Use low gear for climbing and crawling.
• Slow Blinking Red (when Low-Voltage
Detection is activated): The XL-5 HV has
entered Low-Voltage Protection. When the
battery voltage begins to reach the minimum
recommended discharge voltage threshold for LiPo battery
packs, the XL-5 HV will limit the power output to 50% throttle.
When the battery voltage attempts to fall below the minimum
threshold, the XL-5 HV will shut down all motor output. The
LED on the speed control will slowly blink red, indicating a low-
voltage shutdown. The XL-5 HV will stay in this mode until a fully
charged battery is connected. If you see this code because a NiMH
battery was connected to an ESC with Low-Voltage Detection
turned on, then follow the calibration steps from the previous
page to release the code and change the ESC to NiMH mode.
• Fast Blinking Red and Green : Overvoltage.
This code can appear when a fully charged
NiMH battery is connected to the XL-5 HV ESC
with Low-Voltage Detection turned on. Follow
the calibration steps from the previous page to
release the code and change the ESC to NiMH mode.
• Fast Blinking Green: The XL-5 HV’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.
