Elevator trim disconnect on AP not working in 4.28

[deetee]

Just done a fresh install of FSX SP2.

I mapped one of the axes of my CH yoke to the elevator trim, which works fine but messes up the AP ALT hold function.

So I activated the "Elevator trim disconnect on AP" function in FSUIPC.

However with the AP activated the trim axis still affects it, and wiggling the lever still moves the trim.

I'm using FSUIPC 4.28.

Thanks for your help.

David.

Edit: OK I just realised this only works if you assign the elevator trim in FSUIPC.

Sorry about that. :oops:

I wonder why FS does disconnect it?
