Interesting, I havn't noticed any tendency to hunt in yaw or any sensitivity in the rudder response in my SS. Tho admittedly I havn't flown any of the other models yet so maybe it's there and I'm just not aware of it?
Some right rudder is needed in powered cruise flight, tho, and I still have the same bungee cord strung around the bottom of the right rudder pedal that JD originally put on the plane. It's basically practically perfectly coordinated in cruise flight but of course when you drop the power you have to apply left rudder to counteract the bungee. With no power the rudder pedals are virtually perfectly centered.
Maybe this is why my plane doesn't hunt in yaw, perhaps because the rudder is always lifting slightly to the left anyway.
I don't have a wheel pant on the front wheel but I do have the regular pushrod steering so the wheel does turn in flight when I apply rudder.
If anything the rudder seems to me to be well harmonized with the other controls at cruise speeds, and definitely diminishes in authority when the power is reduced and speed is slowed. In fact, I was practicing cross-controlled stalls the other day and found that as I approached stall the rudder was scarcely able to keep the plane uncoordinated (tho it still could a little bit).
As for the Pilatus..... pshaw... the view is better in the titan by a long ways for sure :)

I believe that this feature allows the additional yawing moment caused by the turning of the front wheel in flight to be eliminated from the equation of why the Tornado has a "yaw problem".

It's been explained to me that the long slender nose of the Tornado provides some blockage of the airflow over the vertical stabilizer giving some tendency for that surface to "hunt" for smoother airflow off the axis of movement.

PC-12 is a systems airplane and "George" (the autopilot) did most of the flying. Handling the airplane by hand, like most larger aircraft, felt like driving a truck without power steering, as compared to the Tornado that is more like a go-kart with much better visibility! I've flown both and the Tornado is way more FUN!
