Switch to the next tab: Basic Configuration of the Copter.

Under System Configuration, you can set the PID loop frequency. Ideally, it should match the gyro update frequency. On F4XX flight controllers, a PID loop frequency that is too high can overload the processor. In that case, select half of the gyro update frequency. F7XX flight controllers are not affected by this.

The accelerometer must remain enabled. The barometer depends on whether it is installed. The magnetometer should only be enabled once it has been set up and the GPS functions are fully working.

Below these settings, you can give your copter a name and enter your pilot name. You don’t need to set the camera angle, but you must set the maximum armable tilt angle. For example, if this is set to 25°, the copter can tilt up to 25° and still arm. If it’s set to 180°, the copter will arm even if it’s upside down. This is useful for the Flip-Over-After-Crash flight mode (also called Turtle Mode).

Under Other Features, you should enable AirMode and, if you use it, also the OSD.

In DShot Beacon Configuration, you can configure the “Motor Beeper” if your ESC supports it.

• RX_LOST makes the motors beep when the radio signal is lost.
• RX_SET allows you to activate the motor beeper using a switch on your transmitter.

The beep configuration listed below this refers to a separate, dedicated buzzer. The effect of each mode is described right next to it.
