After that, ANTI_WINDUP is deactivated until next arm. Useful for airplanes. <br />THROTTLE_THRESHOLD is the Airmode behavior known from Betaflight. In this mode, Airmode is active as soon THROTTLE position is above <i>airmode_throttle_threshold</i> 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. Airplanes default to STICK_CENTER_ONCE mode."
