For all using a MSFFB2 or another FFB stick and stuggling with force trim, try this:
Swap X and Y axis on your stick over the 'FF Tune'-Options in your control bindings. This stopped the jumping of my ffb stick when i used the force trim button. Now it stays physically in the position when i press force trim, like expected.
My rudder is on the Z/twist axis of the stick, and set to 'Central position trimmer mode'.
I really struggled using force trim with my MSFFB2 on the AH-64 the whole evening, but now it makes sense and is pretty cool to use.
