ESC calibration

Electronic Speed Controllers (ESC) translate the input from the RC or the flight controller to the motors. ESCs do not always have to be calibrated. High-quality controllers come with a factory calibration and can be just configured using the PWM_MIN and PWM_MAX parameters. This ensures that all the ESCs in a multicopter will scale the same way the input from the Flight Controller (FC) to the motors. However, many low-cost models do require calibration and so if unsure calibration is recommended. Here is how you do it.

Never attempt ESC calibration with props on. Before you begin just remove them.

For the calibration process to begin you should use only the USB connection to the flight controller in the first step.

ESC Calibration step 1

Then you will be asked to plug in the battery.

ESC Calibration step 2

The calibration will begin automatically.

ESC Calibration step 3

Wait until it is finished.

ESC Calibration step 4

You are done. Now the ESCs are calibrated.
