I have had this happen to two different aircraft of the same exact make and components. When the mission completed the aircraft descended uncontrolled but at a slow decent rate and a pirouette. The aircraft didn’t respond to controls from either the RC controller or Mission planner. Both times this happened the flight went smooth, no issues except at the of the mission. Both aircraft have been flying for a while now.
One aircraft has the pixhawk v1 the other was a 2.1 cube.

I didn’t notice any clipping or EKF issues.
