Interesting you say that. Now that I think about it, it was a 152 that
originally scared the crap out of me. It dropped left so fast and hard
that I felt like I did a 360 before I had time to react. When I
recovered, my heading had changed 180 degrees. The 172's were much more
docile when dropping a wing - still unnerving but not so surprising.

On the spin topic, though, I asked two different instructors (at two
different schools) for some spin recovery demonstrations. Although it
was probably frowned upon by the FBO's, both CFI's were happy to oblige.
We had a hell of a time getting the *152* to drop into a spin but
the 172 did it with ease.

Maybe it was instructor technique, maybe it was other factors...
