Default Min Max
1300 1000 2000

airmode_type

Defines the Airmode state handling type. Default STICK_CENTER is the classical approach in which Airmode is always active if enabled, but when the throttle is low and ROLL/PITCH/YAW sticks are centered, Iterms is not allowed to grow (ANTI_WINDUP). THROTTLE_THRESHOLD is the Airmode behavior known from Betaflight. In this mode, Airmode is active as soon THROTTLE position is above airmode_throttle_threshold and stays active until disarm. ANTI_WINDUP is never triggered. For small Multirotors (up to 7-inch propellers) it is suggested to switch to THROTTLE_THRESHOLD since it keeps full stabilization no matter what pilot does with the sticks. Fixed Wings always use STICK_CENTER_ONCE or STICK_CENTER modes.
