I recorded a video showing an anomaly visible even on the stick itself. The movement is performed exactly the same to the left, then to the right (with the same force, angle and speed by my hand). To the left, everything works fine; the plane reacts rather sluggishly at this weight, but to the right, the movement is immediate, abrupt, and overly sensitive. In flight, it looks like the plane rolls correctly to the left, but the roll rate is excessive to the right, which means the plane is even capable of performing a quick roll like a light jet (a Hawk, say). The axes should operate at the same deflection and speed to the left and right, but they don't. To the left, it's fine, but to the right, it behaves completely differently, resulting in a flight model issue.

This is clearly a bug. It may have been fine before, but any update requires tuning for Vulcan as well.
