Axis Does Not Hold Surface In Position

Recommended Posts

I really hate to be a bother but I think I'm missing something.  I am trying to set my elevator axis. FSUIPC recognizes the axis as "Y" and when I move the joystick forward (away from me) I have a value of +16383 IN and +16225 OUT.  When I move the joystick back (toward me) my values are  -16384 IN and  -16384 OUT.  The Delta number is 256 and, in neutral, the values are  +128 IN and  0  OUT.

 I clicked the ok button and went back to the airplane I'm using (Cessna 152, because I know it has cable and bellcrank controls) and I got an elevator deflection trailing edge up (climb) but then the elevator immediately snapped back to neutral.  It was the same way when I tried trailing edge down (descend).

I can't figure out what I'm doing wrong because the aileron axis works fine. The aileron axis is recognized as the "X" axis.

Sounds like something is resetting the elevator axis, whether this is your axis assignment or something else.
Can you please activate logging for Axis Controls and generate a log file showing your issue, and then attach that as well as your FSUIPC7.ini file.

Please also check to see if the elevator or any elevator controls are assigned in MSFS, and also check the assistance options as these can sometimes do strange things.

As you are a relatively new forum user, you will have quite a low upload limit for your files. You can try compressing/zipping them, but if they are still to large you can email them to me (jldowson at gmail.com where at is @).

I checked for activation of logging for axis control and it already had a checkmark next to "axis control."

I do not know how to generate a log file showing my issue.

I assume that I can copy and paste an attachment by using the paper clip I see at the bottom of this post, but I have no idea where to find the FSUIPC.ini files.

Sorry, I am not computer literate but I am learning.

You log file is generated automatically, and is available in the same place as your ini file - in your FSUIPC installation folder. If you do not know where this is, you can use the File -> Open Installation Folder... menu option.

You can drag and drop files to the paper-clip section to attach them, or click the Choose files link.

But you should at least be familiar with the basics of FSUIPC. I provide extensive documentation - at least familiarize yourself with the User guide.

Did you check your assignments in MSFS, as well as the assistance options, as advised?

OK, Here are the files as of 5/28/2024 12:39 PM.

Hope you can tell me what is interfering and thanks for the help and direction so far. I went through the assignments, I have no peripheral assignments to the elevators and I checked the assistance options and turned all of the flight control assistance options off.

You have assigned two of your Logitech Extreme 3D axes to the elevator:

Quote

1=AY,256,F,65762,0,0,0    -{ TO SIM: AXIS_ELEVATOR_SET }-
2=AR,256,F,65762,0,0,0    -{ TO SIM: AXIS_ELEVATOR_SET }-

So what is happening is that you are moving the elevator assigned to the Y axis, and occasionally you are getting a signal from the R axis which is resetting the elevator position to that axis. Remove that 2nd assignment - the one in bold (best to do this when FSUIPC7 is not running).  You should only ever assign one controller axis to each aircraft axis per profile.
