Coincidental for me that this came up. Just curious Silver, but did you change anything about how your stick setup is mounted to your desk/whatever?
I recently got around to mounting my HOTAS solidly to my chair, sort of a cheap DIY gaming chair setup. The first while I flew in it, I discovered if I pulled hard to break turn, I would sometimes go into wicked accelerated stalls out of nowhere, where before I would've just pulled near blackout.
I realized the issue was my previous setup was highly unstable, on a surface with a lot of give to it that effectively was damping my control inputs. I'd pull hard, the surface the base of my stick was on would give slightly, then go to the deflection I wanted.
I wound up having to relearn my muscle memory, and it still bites me in the backside now and again.
Just throwing out another possibility.
