Getting ready to do spins for CFI training, which means not only do I get to
perform them, I have to delivery a ground lesson on them first as well, so
I'm gathering all the data I can find.

Information I have says that in a developed spin most light airplanes make a
complete turn and lose 500' about every 3 seconds.

Does anybody have information to the contrary? I haven't done spins since
1990 so I don't remember the numbers exactly.

Set up a simple stall at, say, 3000 AGL and time the descent to 2000
AGl.
Should give you an idea as to the numbers
