Power Climbing and Lift Climbing? Is that sort of like a thrust column? Or shooting across the circle?
There are no WWII fighters of which I'm aware that had the power-to-weight ratio to hover or even get close to it. You might "power climb" for a very short time, maybe several seconds even, but if you aren't above flying speed and making lift, you'll very soon be in a rapidly-descending spin, usually but not always to the left, but always out of control if you hold it in a climbing attitude ... indeed, if that is even possible in a fully-developed fighter stall. Mostly, if not all the time, they buffet maybe, break, mose over, and depart under power. That assumes a coordinated stall, not cross-controlled. If not, you WERE going to spin and maybe not recover under power.
There weren't any "flat rudder turn spins" in WWII. Once it started rotating, it was going around and down. They still do that, even today. Large, heavy engines are not good at hovering, but they drop exceedingly well, even while operating at full throttle. Most have the glide ratio of an anvil.
