Turbine-powered helicopters have hydraulic controls, and usually there is no "feel" for the center (neutral) position. And since the X56 stick comes with a spring to hold it in the centered position for that "trimmed" feel, the spring is easily removed, thus providing for a "limp" feel for the pilot. This, then, is the same feel provided by aircraft hydraulic controls.
The S-76 when lifted to a hover from a stationary position, rears up on the main wheels as you'll see in this video. A rolling takeoff is generally preferred for passenger comfort.
The video to the left shows a rolling takeoff from a downtown street. A word about how X-Plane provides for trim; elevator, aileron, rudder, or helicopter rotor. With the installed spring, a simulator pilot might need to hold pressure against the spring to maintain a desired aircraft attitude. As the pilot "trims," the view adjusts such that a certain point the view is maintained without pressure against the spring. Thus, the aircraft is in trim. Again, with hydraulic controls, there is no trim feel, which is why I simply remove the spring for such aircraft.
Below you'll see a landing approach and a roll-on landing. You'll also see a bit of a side slip such that the pilot as a view through the chin window. Typically, transport helicopters, because of the instrument panel, provide a terrible view over the nose. An antidote is the side slip until just before touchdown.
