I fly stalls and spins, loops and rolls about once a month, just to maintain proficiency.
When I'm mentor flying, I occasionally hover the controls, not to "help" my charge, but to upset the plane more, to show then what they should be comfortable doing in it.
I remember being timid, until the learned pilots started showing me what a plane would actually do. The most extreme of this, was during a flight in a C 185 amphibian, as I asked the pilot owner if a plane with that much hanging below could be rolled. He said "Hmmm, I don't know..." Moments later, we both knew, yes it could!
