Well, the trim commands in the current MSFS helicopters are called:
SET Rotor lateral Trim
Decrease/increase Rotor Lateral Trim
SET Rotor Longitudinal Trim
Decrease/Increase Rotor Longitudinal trim
Rotor trim reset
I’ve never actually tried rudder trim in a helo, as usually when you pick up speed, the tail boom makes sure you dont sway in the wind much, but tail rotor controlling is crucial in the takeoff and landing speeds, as you’ll be balancing on a needlepoint to make it from drifting away from you.
basically just enter ROTOR into the search bar in controls, and all the possibilites pop up.
As for the twisting of your stick to at leat 60%, go into assists and turn the helicopter assists off… it feels like you’ve got them set to “give me all the help you can”… Go to assistance options->piloting and turn them off there. And walk through the other menu’s as well, to see what else you can find that you won’t/dont need… if you find flying too spectacular as of hitting Apply and save, turn 'm back on.
Before takeoff, i usually set most helicopters up by holding the lateral trim forwards for one second and the longitudinal trim also hold for one second forward… this makes for easier takeoff’s as usually, you’ll be pushing the stick forwards and to the left from center quite a lot… whilst also trying to hold the tail straight… this makes for a wealth of combinations of inputs from you, the pilot… setting the trim a bit more stable on forehand makes a job a bit easier… still complex, but easier.
Hope it helps, Good luck.
