I trained on Tiger Moths (note - I didn't say I learned to fly on Tigers; I'm still learning after nearly 50 years). I note in my logbook that I did a solo spinning detail after 9hrs50mins dual and 8hrs50mins solo.
What sticks in my memory is that I was so "concentrated" on the spinning exercise that my first attempts at putting the aircraft into a spin came to naught because I forgot to lock the slats. Once this oversight was sorted, she spun like a dream.
All of our Tigers had slats, so I have no experience of flying without them.
