Fred,

Thanks,

Okay...regarding the overly sensitive rudder I am experiencing....this encouragingly seems to be a solution:

In the FSUIPC5.ini I changed the joystick calibration value limits for my rudder to about double that what they normally are. In other words those pot value limits are normally about -16,380 and 16,380. I changed those respectively to -32,000 and 32,000.

So the result is that at full deflection of my rudder pedals the effective rudder output reading is cut in half. That shows up exactly as you would expect on the MFD controls page for rudder movement. I kept the slope response as linear.

I just ran some aborted takeoff runs on the ground and can very nicely control the rudder steering at speeds of 145+ knots.

I need to test the behavior in the air. I am going to try to duplicate the conditions of my crosswind flight that I had a problem with yesterday.

Since this only changes a joystick input parameter I would not expect that it will have any influence on any autopilot functions.

Perhaps this item needs to be discussed in a separate thread though.

Update:

Completed a couple of test flights.....

Was able to control things much much better in that crosswind landing with the above mod!

Fred,
Can you post the changes you made? I am hoping its the same in 4. I looked in my FSUIPC.ini and there are many numbers listed so not sure which ones to change. Really appreciate the assistance here.. It continues to get better with every update

Thanks,
Jimmy Mac

In your FSUIPC.ini make this mod to the "Rudder" line:

[Joystick Calibration]

Rudder = -32000, -1000, 1000, 32000/16

These values are normally generated in the FSUIPC joystick calibration module within FSX/P3D which writes those values to the ini. You can also modify them directly in the ini as I have done. The "32000" figures are your pot limit calibration settings that are normally around "16380". The "1000" figures are the null zone calibrations which you can leave as to whatever those numbers are in your setup.


Mark...Do you see any valid logic in pursuing it this way relative to what goes on with rudder control settings on your side of things? This does dampen my manual rudder control significantly resulting in much improved handling performance. And as importantly, it does not seem to be affecting any flyability characteristics of the aircraft other than that. At least not that I can see at this point other than the rudder control output scale on the MFD display. I am just seeking your assurance and blessing that nothing else will be affected.

Hello

I confirm unable to fly with 1.83, the yaw damper goes right to left like a crazy.

Just after put bat on i have the ball is not centering






A video

How fix that?.

I found this issue since 1.77, sometimes with 1.80.

Many thanks,

Emmanuel

Fred,
Interesting result, I made the changes and I could not control the aircraft on the runway it went left and would not straighten out. Do I need to recalibrate after making these changes?

it does look the same in FSUIPC4 my existing settings
Rudder=-16292,-1285,-1285,16246/8

Thanks,
Jimmy Mac

Be precise with your entries......that third value should be a positive 1285. Also try changing the slope value 8 to 16.

I can't explain what it's necessary to change these values, i will do because also unable to control aircraft when rolling

In FSUIPC always make sure the "OUT" box has a "0" after you move the control. 0 means it is centered, disregard the IN number or the SET numbers. Creating the slight null zone before clicking on each of the 2 center set buttons will get you that "0".

The -1285 that Jim mentioned would make it go left. If you centered the rudder and had -1285 in the out box get ready to go left.

Fred,
Success I made the changes and am dialing in the controls!

Steve,
Thanks for the added explanation. the original setting were great if I was running Nascar and always turning left!

vaidorge,

I made the changes Fred posted here to the Rudder setting in FSUIPC.
I had to make the second entry a positive number and the third a negative number. I changed the last entry from 8 to 16.

Once in the flight sim I launched FSUIPC and per Steve's advice ensured that the out box was "0" after moving the controls. I then tested but discovered that the rudders where reversed so I had to uncheck "rev" in the rudder section.

Continueing to test but thanks to the effords by everyone on this post I finially have better and I think more realistic control..

Thanks,
Jimmy Mac

Many thanks Jimmy

One précision, do you force the value as requested. Or not?
