AnKor, keep up the good work. As I mentioned in my earlier post, the back and forth motion is noticeable in career and not in QC. Are flight models different? Does WOFF add something to career that isn't present in QC? Maybe this can set you on the right path to solve it?
I wish the AI could "benefit" from this mod when shooting me down.

The connecting rod out of my brain, my brain,
From out of my arse take the camshaft,
And assemble the engine again."
