Hi Tailspin45,
one thing
is unusual (no offence meant

): There's a "__MACOSX" folder in the archive - do you run IL-2 within MacOS (with Wine)?
In any case, the symptoms you describe may result from
- Your hardware is sending funny stuff (test with "usb game controllers", properties)
- YaDeLi is
receiving funny stuff (it uses DirectInput, DirectX)
- YaDeLi is
sending funny stuff (however unlikely that is

)
- IL-2 is receiving funny stuff (network garbled, proxied,

)
- IL-2 has some inner conflict (controller shizophrenia - but you've solved that apparently)
We would have to check that step by step.
