In the Betaflight Configurator, you can use the Modes tab to decide how your copter reacts to certain switches or sliders on your transmitter. Each mode is assigned to a channel (AUX1, AUX2, etc.) and is activated within a specific switch range.

The channel numbers depend on how your transmitter is set up. Usually, AUX channels beyond channel 4 are reserved for switches.

General Procedure:

1. Turn on your transmitter and open the Modes tab in Betaflight.
2. Select a mode from the list, e.g., ARM.
3. Click Add Range.
4. Move the desired switch on your transmitter—the corresponding AUX channel will move in the display.
5. Adjust the yellow range with your mouse so it covers the switch position you want.

Repeat this for all the modes you want and don’t forget to save.

Important Modes and Settings

1. Arm

• Function: Activates the motors when you give throttle.
• Settings:
  • Select ARM in the Modes tab.
  • Assign a switch (usually a 2-position switch).
• Safety note: Motors can only arm if no warnings are active (e.g., Failsafe, GPS lock missing, throttle not at minimum).
• Tip: Use a switch that’s easy to reach but not easy to trigger by accident.

2. Beeper

• Function: Makes the copter beep, helping you find it after landing or a crash.
• Settings:
  • Select BEEPER.
  • Assign a switch.
