Flying a YAK is just the aerial equivalent of ploughing with my 1975 David Brown Tractor!
You can complete your mission profile in many other "cheaper to run" aircraft.
If you do buy one - get spin training from Gennady.
For 3 years I took off to display after he landed: he'd run down the centre line, downwind, max chat, erect 100' - pull up to the 45. As speed decayed he'd half-flick to inverted - start the pull through, pop the gear and land on the numbers.
I'd be lining up to go as he exited and still recall shaking my head at the audacity of the act (and the safety gates that were built into it!).
