The very first BAC 1-11 prototype was lost to a deep stall during flight test, the design was altered to include a stick pucher. Much attention is given to avoiding stalls during 1-11 training, this must work, since I never heard of another 1-11 being lost to a deep stall.
Aerodynamics change from one design to the next, each particular design is (supposed) to be equipped with the type of stabilizer that best suits itīs own particular flight envelope.
