I learned to fly on 150s back in the '70s.
Best thing about them? The 40 degree flaps.
Worst thing? Appallingly rubbery unresponsive handling (but no worse than any other spamcan, better than some, not as bad in this respect as the truly awful PA28).
If all aeroplanes handled like (think 2CV) that I'd have walked away from flying immediately following my PPL. Brian Lecomber was right when he referred to spamcans as 'an insult to the airman's art' in his ecellent book, 'Talk Down'.
But they are tough, and cheap to buy and run, so still form the basis of the training fleet at many clubs. Pity the 152 dropped those lovely barn-door flaps!
