I learnt in the tomahawk and my instructors and I did many spins - they actively taught them in 1983 ? ............... They even told me to go up solo and do spins which was done
after I got my ppl I used to take thrillseekers up to do spins (in hindsight probably not a good idea)
I think then the NZ authority directed no more spins in the tomohawk so that stopped - a pilot thereafter died when his tomohawk went into the sea from circuit height - cause not known
I'd gladly do some spins again - with an instructor though first off
