As part of an aerobatics course, we used a 2-32 for all the spin training and really wrung it out trying all kinds of things to screw it up and recover. The 2-32 does do some weird things. For example, if you put the control inputs in to recover in the wrong order, it may not recover. You have to go back to the full spin position (rudder in direction of spin and stick full back) and start over. Sometimes the spin would stop and it would immediately spin the other way. In training we could get quite a few turns in, trying to accelerate the spin, slow it down, mess it up on purpose and recover, but we had plenty of height to work with. I've had flights where the instructor would just say, " that was interesting, never saw it do that before." One experienced instructor (now and aerobatics instructor) referred to a spin in a 2-32 as a "come to Jesus" moment. Anyone wanting to really learn all about spins should get some specialized training in a 2-32 before the last of them is unfortunately destroyed and people flying them recreationally should make sure they are truly proficient and comfortable with spins. There's a reason NASA bought one and outfitted it with equipment to try to better understand what happens in a spin.
