Chapter 10: ESC Throttle Range Calibration

After assembly, calibrate the ESC throttle range while the ESC is connected to the flight controller. Before calibration, remove all propellers and ensure that the motors cannot contact any surrounding objects.

Procedure:

Connect the flight controller to the computer with a USB cable, open the MP configuration and tuning software, and connect to the flight controller.

Set the radio transmitter mode switch to Manual mode

Under “Flight Data” → “Actions,” click “Arm/Disarm” and confirm that “Armed” is displayed. Move the radio transmitter throttle to its maximum position, then connect the propulsion battery to the ESC. If the ESC main power leads are soldered directly to the positive and negative terminals of the flight controller power distribution board, connect the propulsion battery directly to the flight controller. Wait for the ESC battery-detection tones (the tone sequence may vary by ESC), then move the throttle to its minimum position. A long confirmation tone indicates that the ESC has accepted the minimum throttle value. The throttle range calibration is now complete.

For a twin-motor aircraft with two ESCs, calibrate each ESC separately. While calibrating the first ESC, disconnect the second ESC signal cable from the flight controller Servo port. After calibrating the first ESC, disconnect its signal cable, connect the second ESC signal cable, and repeat the calibration procedure for the second ESC.
