It seems not friendly for FFB2 .

I cannot  change curve for FFB2 in the AH-64 like MI-8, because that will cause the trim is not working properly. But it is too sensitive for FFB2 in AH-64 It almost impossible to make AH-64 stable in the low speed.  It even more difficult than Mi-8.

Old issue that trimming doesn't get the curves applied. Sadly this hasn't been fixed yet. We're basically stuck at linear axis input for the stick. If only there was a modern FFB stick / base that's not over a grand and actually works with DCS...
