FSX elevator control jerky

Recommended Posts

Hello,

my assistance here...user of FSX and FSUIPC 4.971 on Win 7 system.

I just returned back from my 3 month overseas roaster and fired up FSX for a routine flight...only to note quite a stiff yoke (PFC VMax Flight System)...tried a takeoff but had no elevator control whatsoever...rest of controls and push buttons work fine.

I need assistance in determining if it is a hardware issue and the yoke needs repair or some setting that has gone wrong while not using FSX for the past months.

I tried calibration under windows game controller settings and can note that the cross hair only travels to half way down the calibration box.

I then re calibrated in FSUIPC for elevator only and get -16383 for elevator down with a smooth delta (256) but then on elevator up I get 3 readings of 4067, 11000 and 16383. In FSX I note the aircraft elevator having a slight up movement and then it bangs its way fully up with no transition in between.  I tried another simple joystick, calibrated through FSUIPC and all was working normal.

Any assistance or trouble shooting would be greatly appreciated...this yoke had cost me a fortune and would really like to continue using it.

Look forward for any help.

Regards,

Emann

Hi,

seems more like a Yoke problem.

I guess you did the calibration in FSUIPC after you re-calibrated in Windows. FSUIPC uses the Windows API, it means it gets the calibrated Windows data. FSUIPC calibration uses the Windows basic data.

Also any earlier version than the current is not supported, you should update in any case, links are below. First using the installer for 4.974 before udating to 4.974b

FOR FSX, FSX-SE and Prepar3D

Install complete FSUIPC version 4.974 Install FSUIPC4.974 for FSX, FSX-SE and Prepar3D versions 2.5, 3.0 - 3.4 (32-bit only: all versions to date of release)
Changes since 4.96 are now included in the History document in the FSUIPC Documents folder supplemented by the Changes document in the ZIP.

FSUIPC 4.974b DLL only, for current 4.974 users FSUIPC4974b.zip
-- This interim update provides an improved Lua ext library. Those included functions operating on external application windows now more reliably find and act on the top level window, as generally necessary to have effective keyboard and state changes (min/max etc) recognised and acted upon.

Also please always attach or copy and paste the content of a fully closed session of FSUIPC4.log and FSUIPC4.ini files. 

What do you see on Axis tab for the input value of elevator axis, already the same jerky?

Hi Thomas,

thank you so much for your reply.

I will check for the update of FSUIPC later on and install when on the simulator computer....how do I access the log file please and then will submit this with the ini file as well.

In Axis tab the input of elevator back is jerky as well. I mainly get three readings of 4067, 11000 and 16383 and cannot set the delta either.

Look forward for any assistance.

Emann.

Hi,

the files are located in ..\FSX\Modules folder

If you cannot see the file extensions, .log / .ini / .txt, make sure you have the following option in File Explorer un-checked
