But, how can any pilot, who is not "line flying" the aircraft in question, completely understand the technical nuances of the particular aircraft, to a point where he can adequately cope with any eventuality? I'm guessing that the Hunter (or any other vintage aircraft) has plenty of "characteristics" that can only truly be mastered with many, many hours of familiarisation...
Practice, practice, practice, and if you can't afford that, either time- or money- wise, then back off the level of difficulty or risk that you expose yourself to.
