+# VTOL Configuration
+
+First perform the [Standard Configuration](../config/index.md).
+As part of this you should calibrate the [Airspeed sensor](../config/airspeed.md) (optional, but highly recommended) and [assign a VTOL transition switch](../config/flight_mode.md#what-flight-modes-and-switches-should-i-set) to your RC controller.
+
+Then perform VTOL-specific configuration and tuning:
+
+- [QuadPlane Configuration](../config_vtol/vtol_quad_configuration.md)
+- [Back-transition Tuning](../config_vtol/vtol_back_transition_tuning.md)
+- [VTOL w/o Airspeed Sensor](../config_vtol/vtol_without_airspeed_sensor.md)
+- [VTOL Weather Vane](../config_vtol/vtol_weathervane.md)
