bcpilot is pretty much on the mark. A "few hours" is getting correct, the half a dozen spins you need to get in your logbook to instruct is pretty worthless. Quite often the second time the instructor spins is when he is signing off his first instructor student
. So we have somebody who doesn't know how to spin teaching the maneuver to somebody who has never spinned. Recipe for disaster, treat spinning with respect, especially when you are an instructor with passengers.
