I have no doubt that you're telling the truth. So no need to prove anything. I'm just trying to imagine what kind of control inputs you must be putting in, to manage the moves you mentioned.
There is a selection in the data output section that will show control surface inputs. I would actually be very interested to see what you're doing in that regard.
I can tell you the ground handling is being overridden with code, but Saso is the authority on that. Ironically, I think it's the low speed taxi ground handling that is being overridden.
It's widely known that X-Planes ground handling needs some tweaking, so maybe this is what you're experiencing at higher speeds.
