SW FF2 and FSX- No effective Rudder control

Everything else works very well -but the rudder control is extreme and uncontrollable.
Tried sensitivity zero etc etc. No success.
I’ve looked at FSuipc but the freeware copy I found doesn’t do anything.
Does anyone have a definitive solution?
Thanks for any help and assistance.

Just checking to be sure… do you have your Options/Controls/Primary Flight Controls/Rudder Axis assigned to your joystick twist action?

Yes, it’s definitely set up to axis Z.
I’ve even tried modifying the “Flight Tuning” - Rudder_effectiveness down to 0.6 then 0.3 in the aircraft.cfg of my favourite Warrior II with no improvement.

Having the sensitivity at 0 means you are getting a straight linear response.
You want to take some of it away, use the ( - ) section of the sensitivity control.
As well, you may want to take away some of the reactivity, so it doesn’t react so quickly to the inputs.
