On most AH planes torque feels very moderate, even the ones that were notorious for it. If this is how it was in reality, I don't see what the big fuss was about.
The flaps are just being abused due to the ability to fly at 80 mph, full throttle+WEP and wiggle the stick around without danger of spinning out of control. In principle, when flying close to the stall, full "roll" deflection of the stick can stall the outer ("rising") wing - it never does in AH, at least not that I felt it. As far as I remember, the only plane that felt like this was the old 109 flight model that made it very tricky to fly at slow speeds unless the player had a good stick and very steady hand.
Absurdly, the old bugged mosquito with the misplaced centre of gravity felt the most "correct" to me. Sure I was campaigning to get it fixed, but even back then I said it felt how most planes should handle. It is still one of the very few planes than can be stalled violently into a spin (try stick full lower left + full left rudder and hold on to you panties).
