Not sure if this contributes to the thread but I experienced high rotational spin in a Bulldog I was flying for the first time for no other reason than the harness lock was too low down in my midriff which prevented full back stick.

Made for an interesting ride and taught me to make sure it was in the right position on the ground in future!!! Nugget!!!

Interesting to hear about high rotation spins in bulldogs,back in the early 80's whilst at summer camp (cosford) with a UAS,I returned from lunch to find a 'pale' looking crew.They had experienced a high rot spin and I got the job of trying to figure out why,after scratching head for a few hours and checking rigging/airframe etc...the only anomoly I could see was that the elevator tab was set a bit lower than I would normally rig it,from memory the rigging procedure was a little vague anyway and also that the setting for spinning was in 'take off range'-also a little vague.
I also set the elevator range nearer the max 'up' (it had been in the mid range)- the resultant air test gave the slowest spin in our fleet,but myself and the boss were happy that the a/c was ok.
The engo at cranners did not seem to agree that with the stick on the backstop the elev tab was merely acting as the trailing edge of the elevator and no longer a tab and the a/c ended up at Shawbury for months where Marshalls could not find anything wrong with it.
