I have been reading about RAAF fighting tactics. In a Spitfire or a Kittyhawk, a bunt was the best and possibly only way to get a Zero off your tail. In a Spit it was full left rudder, full left aileron, and full nose down. Described as everything in the corner. In a Kittyhawk it could be either left or right corner. Either way, it was a minus 5 g manoeuvre.
I am trying to visualise what the plane would actually do in a bunt. You would certainly need some altitude to recover.
