@=617= Evil
Leave the curve and play with the -Y saturation, defaults will be 100 percent so start by taking just 1 or 2 percent away for the role.
Do the same for the pitch using -Y saturation, this time you can afford to use a little more however don’t go lower than 78%.
Using curves are great for analog controlled jets and choppers, anything FBW you want a default linear curve and only play with just a few percent on the -Y saturation. I would avoid adjusting saturation and linearity both together.
hope this helps.
