This is Ken Sasine. I am a graduate of and former instructor at the USAF Test Pilot School. I also taught at the National Test Pilot School at Mojave California. While in the latter position, I taught spin testing in gliders and the Chipmunk. Our Chipmunk was a standard model with the Gipsy Major engine.
That aircraft has very straightforward spin characteristics. One of the amusing (and at times inconvenient) things about the Gipsy Major is that it would quit after about 5 turns and have to be re-started after having recovered from the spin.
I have not flown the Super Chipmunk, so I can't comment on the differences. Clearly, the clipped wings would allow a faster rotation rate. Having watched Art Scholl on many occasions, that became apparent during his routine. The snap rolls were very abrupt, with high roll rates.
I am presently flying a PZL-130 "Orlik" for its owner, and have done extensive spin investigations in that aircraft. It is a Turboprop Military Trainer similar in appearance and flying qualities to a Pilatus PC-9 or PC-7.
I'd be happy to discuss this further at your convenience.
