Have no idea what the trim wheel sounds like in the real airplane, but it does sound familiar from FSX days. Heh, I must have gotten used to it somewhere along the way, because I never noticed it one way or the other until you brought it up. But, yeah, it does make a racket. I have the Cougar 727 cockpit video and I think it's pretty noticeable IIRC, but I'll have to dig it out and give it a watch again.
