4. Setup

Follow these steps for proper installation of the ESC and motor in your RC vehicle.

1. Mounting the ESC: Securely mount the XR10 Justock G3 ESC in your vehicle using double-sided tape or screws. Ensure it is in a location with good airflow for cooling.
2. Mounting the Motor: Install the Justock 10.5T motor into the motor mount of your vehicle. Ensure the pinion gear meshes correctly with the spur gear, allowing for a small amount of play.
3. Connecting the Motor to the ESC: Connect the three motor wires (A, B, C) from the motor to the corresponding output terminals (A, B, C) on the ESC. Ensure the connections are firm. For sensored motors, connect the sensor cable from the motor to the 'Sensor' port on the ESC.
4. Connecting the ESC to the Receiver: Plug the throttle cable (usually a black, red, white wire) from the ESC into the throttle channel (CH2) of your RC receiver.
5. Connecting the ESC to the Battery: Connect the battery connector from the ESC to your vehicle's battery pack. Ensure correct polarity (red to positive, black to negative).
6. Installing the Cooling Fan: If not pre-installed, attach the cooling fan to the ESC and plug its connector into the designated fan port on the ESC.

5. Operating

Before operating your vehicle, perform the following steps for initial setup and calibration.

1. Throttle Range Calibration:
   • Turn on your transmitter and ensure the throttle trim is at neutral.
   • With the ESC off and connected to the battery, press and hold the SET button on the ESC.
   • Release the SET button when the red LED flashes.
   • Pull the throttle trigger to full forward (full throttle) and press the SET button. The green LED will flash.
   • Push the throttle trigger to full reverse (full brake) and press the SET button. The green LED will flash.
