Sokol1 covered all the bases. :-)
Coot, you will not be disappointed with the trim wheel. Since I got mine I found that I have a lot more fun hand flying my GA aircraft. In the past I would turn on ALT Hold to maintain altitude. With the trim wheel, I can set my desired rpm then fine tune my pitch and essentially fly hands free until I hit turbulence of course. It also works wonders on approaches, where I can dial in trim and simply focus on throttle to control my descent.
Enjoy yours when it arrives.
Cheers,
