The trim system works wonderfully. If you were able to add other FFB effects at some point, it would truly take the mod to another level. Especially as FFB sticks make a comeback and are becoming more popular/available to folks at a better entry price point.
The biggest shock factor I had when I flew an actual helicopter for the first time, was the feedback from the bird. Very much something you "feel" throughout the body and stick to know how the bird is reacting.
But like I said, the loach is by far my favorite bird to fly in DCS, and appreciate how raw and mechanical it is. Every input requires precise control of the other inputs. Love it!
