I think we're talking about stall induced spins here. If I am correct, then without apology, I agree with Dick. I've got a foamie that without a bunch of rudder and a little bit of power added you CAN'T get it to spin or do anything but fall flat and to use a "3d" term here "do an elevator". Unless you induce a spin with rudder and power it just ain't gonna happen. When it stalls there isn't the slightest tendency to spin, it just quits flying and falls flat down. Just my two cents.
