I have flown a Robinson 22 (piston helicopter)for about 50 hours and I flew an S76 (turbine helicopter) for a couple hours. In the R22, you move and manually hold the cyclic wherever you want it. However, when I got in the S76, I was all messed up because I would forget to depress and holdthe "Trim" switch on the Cyclic when I wanted to put a new control input in. The Stabilization system (a.k.a. the autopilot channels) did FIGHT me (with a good amount of force). I assume the KA50, although Russian, has a similar system. I feel the trim is modeled correctly in the KA50 with the only "non realistic" part being having to return my joystick to center (of course this has to be done this way for non FFB joysticks). But I dont have FFB, so I dont mind doing this.
Anyway, If people have found easier ways to trim, great! But holding the trim button in to make control inputs would be the most realistic to me.
BTW- I tried hovering the S-76 with the autopilot channels off....uuhh, not so nice, just like the KA50.
