The superstall or deep stall was encountered on the early 1-11s and led to the crash of the prototype. This aircraft had elevators which were actuated by servo tabs which themselves of course would be in an area of very poor airflow. Production examples were fitted with hydraulically controlled elevators which, along with the stick shaker and pusher made it a very safe aeroplane. Trick is not to stall of course.
