Doing the majority of my PPL on the old 152 but my instructor took me up in a PA-38 to show me the differences between an inherently stable airframe and a twitchy one in stall/spin.
Absolutely loved the wing drop and recovery in the Tommy and the spin recovery took a bit of thought along with positive actions.
It taught me a lot. Foremost was the fact that not every trainer will recover from a stall by shouting at it.
Cost me about another 250 but more than worth it.
