I did my flying training courtesy of an RAF flying scholarship at Perth Aerodrome in the 1960s and we were not permitted by the airforce to fly Chipmunks without anti-spin strakes and broad chord rudder, even then spin recovery was a little unpredictable sometimes it would spin flat and recovery would take longer for no apparent reason.
The only problem I had was that being "vertically challenged" ie short I couldnt see over the nose while taxying without 2 extra seat cushions! A beautiful aircraft to fly - years later I flew a Beagle Pup which had nearly the same feel as opposed to the sluggish Cessnas and Pipers.
For medical reasons I could not retain a PPL and turned to engineering and my first A and C licences were on the Chipmunk so even after 40 years I still have very fond memories of the aircraft.
