Fun With a 150
One thing not emphasized in the article in the Cessna 150 is that the non-aerobatic 150 is a great little spin machine. The straight-tail models in particular are wonderful. William Kershner’s book describes how an extended spin will get going faster, then slower, then faster in a cycle.

Climb up to 10,000 feet and you can demonstrate this for yourself. Given how long it takes to get that high, it’s not something you’ll do more than a couple of times, but it’s certainly educational.
