Interesting discussion, as it relates to my old favorite the Gooney Bird. As I recall, VMCA was in the order of 77kts which gave a takoff safety speed of 84kts. It stalled down around 55 kts with full power on both
engines and 65 kts power off at typical takeoff weight with the flaps at zero. Reckon if you were on one donk and pulled it below 77kts with any 'g' at all you'd spin in pdq.
Even the power on stall at landing flap was vicious and could lead to a 90 deg wing drop, but you would have to be silly to even go there as you could get the ASI off the clock towards zero first. No warning when it happens but and the wing drop varies with the amount of abuse the airframe has had over the years, so don't try it below 8000ft.
