Please be reminded the ESC throttle control port has BEC voltage adjustment function to the receiver and the servo, We Suggest DO NOT supply additional power to the receiver, otherwise your ESC may be damaged. 3. Connect to the battery:

Connect to the battery, please MAKE SURE that the (+) pole of the ESC is connected to the battery's (+) and the (-) pole is connected to the (-). If the ESC is connected reversely, your ESC will be damaged. Note: For safety purposes, Be sure the ESC is switched off when connecting the wires to motor and battery as above diagram. Switch on the ESC by keeping the RC unit in the air or on a Stand when you power on. 1. Switch 0 ESC Setup 1. Calibrate the throttle stroke without two in one switch module If the electronic switch module (Switch) is not equipped, The electronic speed controller will be TURNED ON when it detects the battery. 2. Before Calibrate throttle range, ensure the esc is connected to your receiver in channel 2 (CH2) , fully charged battery is connected and a well Calibrated Radio Ready. 3. Please adjust the throttle channel throttle/brake EPA parameters on your remote control to the default values and the midpoint to 0. Note: The throttle must be calibrated in strict accordance with the following sequence, otherwise the car may engage laggy response and may run reversely with the remote control directives. Start to calibrate the throttle First calibration Calibration after restoring factory settings Recalibration After the calibration is completed, the default operation mode is forward and reverse with brake function. 2.

2. Use APP (ISD GO) to set up

The ESC will be in low power consumption state after being powered on if two in one electronic switch modules have been inserted. Turn on: Power on the electronic speed controller, white LED light will be shown on the switch module (Switch). Press and hold the button for one second, the white LED light will turn to steady green (no error message) or flashing red (with error message). Turn off: Press and hold the button until the LED light goes out. In low power consumption state, press and hold the button until the blue LED light is indicated on the switch module LED Light blinking on the switch module will start Bluetooth pairing. The blue LED light will always be on after Bluetooth is connected successfully. And then the ESC can be set up in the ISD APP. If the current throttle range of the ESC is not calibrated, the item Remote Calibration at the top of the Configuration interface will display a red ! .mark Before start to calibrate the throttle range , please adjust the throttle channel parameters of the remote control to the default value and the midpoint of the throttle channel to 0. Begin by clicking the Remote Calibration and the throttle calibration window will pop-up. Follow the instruction to complete the throttle calibration. All other options cannot be set up BEFORE the throttle calibration is performed!

Set the throttle midpoint dead zone. Keep the default value at 0 for most remote controls. If the motor rotates and the recalibration of the throttle range is invalid when the throttle is placed in the mid-position. You need to set a larger throttle mid-point dead zone. 2.0 Turn on/off 2.1 Bluetooth pairing 2.2 Throttle Calibration Note:

2.3 Basic setup 2.3.1 Operation mode a. Forward with brake: In this mode, the vehicle can only move forward and brake. b. Forward /Reverse with brake: In this mode, the vehicle can forward, reverse and brake. This mode adopts double-click reversing mode, that is, when the throttle stick is pushed to the reverse zone for the first time, the motor only brakes. When the throttle is returned to the neutral position and pushed to the reverse zone for the second time, The car will be reversed if the motor has stopped rotating and the brake will still be applied if the motor is rotating. c. Forward and Reverse: In this mode, when the throttle is in the reverse zone, the motor will reverse immediately. 2.3.2 Low voltage protection This function is mainly to prevent the ESC from irreversible damage caused by lithium batteries being over-discharged. The ESC will constantly monitor the battery voltage and will cut off the power output once the voltage is lower than the set data. The low-voltage protection value can be set to automatic (according to the battery type) or manually specified from 5.0V to 12.0V.

2.3.3 BEC voltage The BEC voltage supports manual adjustment from 5.0V to 7.5V (0.1V step). Note:

Wrong BEC voltage setting may lead to damage to the servo or other electrical equipment.

2.3.4 Motor rotation: This item can adjust the motor spinning rotation, moving to the left is the equivalent of the motor turning counter-clockwise, and moving right is clockwise..

- Adjust the frequency under this item. When ESC is set with A lower driving frequency. Motor output will be stronger, the throttle will feel more punchy due to the higher volume of torque; When ESC is set with higher driving frequency , Motor will output smaller torque while being more defined and rotating smoother with lesser noise, but it leads to increasing heating of the ESC and energy demand .

- Adjust the Starting force of ESC under this item. The larger the value, the higher sensitivity of throttle response and the motor increasing throttle output.

- Adjust the braking power under this item. The larger the value, the higher sensitivity of braking response/force.

- Adjust the Forward /Reverse mode under this item. Ensure A non-closed value and the throttle is in the neutral position, the ESC will automatically generate a force that hinders the movement of the motor. A bigger set value , the greater the force generated. 2.4.5 Ramp Anti-Skid lock

Ramp Anti-Skid lock: In Forward/Reverse mode (climbing mode), the active drag brake level is set to a non-zero value to turn on the ramp anti-skid lock function. After this function is turned on, when accelerating movement from a throttle or braking position to a midpoint position, the motor will generate a torque force that is opposite to the current direction of movement to keep the vehicle stationary.This function can make the vehicle stop faster when the vehicle is driving on a flat road, and it can keep the vehicle still on the slope when driving on a steep road. The active drag brake level needs to match the weight of the vehicle. If the level is too high, the vehicle will not be stable in place, and if the level is too low, the vehicle will not be able to remain firmly on a steep slope

This setting is only effective in forward and reverse with brake mode. When this value is set to on, it can produce greater braking force. 2.4 Advanced 2.4.1 PWM frequency 2.4.2 Starting Force 2.4.3 Braking force 2.4.4 Active drag brake level 2.4.6 Active brake enable 2.5 Other 2.5.1 Throttle Curve 2.5.2 Brake curve

Set the throttle curve for stepless adjustment under this item. Note:

In the default novice mode, the maximum power output is limited to 70%.

Set the brake curve of stepless adjustment under this item. Note:

In the default novice mode, the maximum braking force is limited to 70%. 2.5.3 Custom start sound
