• No ESC LEDs will glow when there is no throttle input from the transmitter.
• The red ESC LED glows when there is any throttle input from the transmitter.

• Input voltage
The ESC checks the in put voltage when it is powered ON. If a voltage
problem is detected, the ESC continuously sounds 2 beeps with a 1 second pause
(xx-xx-xx). Power OFF the ESC and ensure the connections are secure and that
the battery power is not too low for safe operation.
• radio connection
The ESC checks radio signal input when it is powered ON.
If a problem is detected, the ESC continuously sounds 1 beep with a 2 second pause
(x--x--x). Power OFF the ESC and ensure the radio system is operating correctly.

eSC funCTIOnS and mOdeS
The ESC includes programming options so you can adjust the way your vehicle performs.
Refer to the included settings table to adjust the ESC for your driving conditions.
eSC prOGrammInG prOCedure
Programming is accomplished using the SET button on the ON/OFF switch.
1. Connect a fully charged battery to the ESC.
2. Power ON the ESC.
3. Hold the SET button for 1 second until the green LED blinks, then release the SET button
to enter programming mode.
4. Press and release the SET button as needed to get to the desired menu option (the green
LED will blink corresponding to the menu item number).
5. When at the desired menu item, hold the SET button for 3 seconds until the red LED blinks.
6. Press the SET button to move among the settings based on how many times the red LED
blinks (Refer to the table for more information).
7. Save the setting by holding the SET button for 3 seconds.
8. Power OFF the ESC and repeat the instructions above to change other settings.
Tip:
If desired, the ESC programming can be returned to default settings
by powering ON the ESC and holding the SET button for 5 seconds.
eSC CaLIBraTIOn prOCedure
Ensure proper ESC function by calibrating the ESC to your transmitter inputs.
1. Power OFF the ESC.
2. Ensure your transmitter is powered ON, the throttle is not reversed, the throttle trim is
neutral and the throttle travel range is at 100%.
3. Press the SET button while powering ON the ESC. Release the button as soon as the
green LED starts to flash.
4. Calibrate the throttle points by pressing the SET button once after each step.
- Neutral (1 flash)—leave the throttle at rest, untouched
- Full throttle (2 flashes)—pull the throttle fully back
- Full brake/reverse (3 flashes)—push the throttle fully forward
5. The motor vibrates for 3 seconds after the last step is completed.

1. running mode
-
Forward Only with Brake
Intended for competition use, this mode allows only forward and brake controls.
-
Forward/Reverse with Brake
This mode is the basic all-around mode, allowing forward, reverse and brake controls.
To engage reverse while moving forward, apply the brake until the vehicle has come to
a complete stop, release brake, then apply the brake again. While braking or in reverse,
engaging the throttle will result in the vehicle immediately accelerating forward.
2. drag Brake force
Adjusts the amount of brake automatically applied when the throttle is returned to the
neutral position. This simulates the engine braking effect of a full-scale vehicle, allowing
improved turn-in and your vehicle’s general response to controls.
3. Low Voltage Cutoff
This function helps to prevent battery over-discharge. The ESC continuously monitors the
battery’s voltage. If the voltage falls below the voltage threshold for 2 seconds, the output
power shuts off and the red LED flashes twice repeatedly.
The cutoff threshold calculation is based on individual Li-Po cell voltage. For Ni-MH batter-
ies, if the voltage battery pack is higher than 9.0V, it will be treated as a 3-cell Li-Po bat-
tery pack; if it is lower than 9.0V, it will be treated as a 2-cell Li-Po battery pack. Example:
for a 8.0V Ni-MH battery pack used with a 2.6V/cell threshold, it will be treated as a
2-cell Li-Po battery pack and the low-voltage cut-off threshold will be 5.2V (2.6x2=5.2).
4. Start mode (punch)
Sets the initial throttle punch when the car accelerates. Level 1 gives
a very soft initial acceleration and level 4 gives a stronger initial acceleration.
5. max Brake force
Adjusts the maximum braking force. A higher value provides stronger braking,
but can also cause the wheels to lock, resulting in loss of control of the car.
The black-shaded setting is the factory default.

nOTICe:
Always disconnect the battery from the ESC when you have finished operating your vehicle. The ESC switch only controls power to the receiver and servos.
The ESC will continue to draw current when connected to the battery, resulting in possible damage to the battery through over-discharge.
