I've started experiencing an awful to diagnose problem.

All my aircraft without exception appear to act like the elevator is fully deflected up, as if the control column is pulled fully back.  It is counteracted by forward control column pressure, but shouldn't happen...

This only began recently...and no I can't pin it down to a particular event or addon.  

Actions taken: (sequentially)

Checked control calibration (no effect)

Changed controllers (no effect)

Deleted generated files (no effect)

Started P3D with zero addons (no effect)

I'm now down to uninstalling and reinstalled the client, unless anyone can come up with an idea for something I've not tried yet?

Cheers K

Have you confirmed the elevator's position and if your controls are moving it?

Hello Kevin

You have gone through the steps of calibrating via  Prepar3D  > Options > Controls > Calibration > Calibrate Device ?

Have you tried changing form RawInput to DirectInput and visa versa ?

Recalibrated yes

Changed input method no

I always disable controllers and assign axis through FSUIPC. - recalibrated theough that as well with controllers disabled in P3D. - no effect.

Elevators deflect as normal , controls work them properly, its just all a/c require significant forward stick to counteract the P3D incurred pitch up.  

Sounds like a controller conflict

You say, the aircraft acts  'like'  the elevator is deflected upwards .  Is the actual elevator visually deflected upwards?   I had this issue once and it was related to the trim being fully trimmed upwards.  

If you are calibrated correctly and your elevator controls are centered in the calibration UI  but act differently in the sim, it sounds like a controller input conflict.

If you disable the trim inputs, does that make any difference?

I had a similar problem recently. In my case when I pressed a key on my Hotas Warthog which was set as a 'Shift' key, the elevator trim would go to fully up. I traced it to the keyboard settings in P3D.  I found that 'Button 3' and 'Button 4' were assigned by default to be ones which controlled elevator trim. These were in addition to the other keys assigned on the keyboard for the same trim.  Solution was to delete the settings assigned to Buttons 3 and 4.  I have just reinstalled P3D from scratch and I normally delete all default button assignments but I missed these 2.
