Fenix A320 rudder issue

Hi Felipe,
Interesting question !
I have never flown IR such a big plane. So my answer is from a theoretical point of view.
Both answers may be correct.

A “precise” modeling would have to take into account the friction forces of the wheels. Here the
programmers would need eperimental data, they probably don’t have.
I assume slip is set to zero under normal conditions.
That would result in an instantaneous change in direction.
When there’s slip and the plane can react only to the rudder input, then inertia dominates,
what would mean you get a delay: first you have to stop the rotation into the unintended direction,
only after that time the plane begins to rotate into your intended direction. In real, sometimes that may feel like an eternity.

Another example for the action of inertia, which you can verify in the sim too ( best with heavy planes during the flare) is the behavior of the plane on elevator input:
When you pull up, the plane begins to rotate slowly, but the downforce on the elevator is there almost instantaneously, so you’ll loose, for example, 10 meters in altitude, until the comparably slow rotation compensates for the elevator downforce with a higher angle of attack.
(Only for models where the elevator is behind the center of gravity)
