A while ago someone was asking how to make a trim wheel. Unfortunately I can not find the request again, and to tell the truth I am not sure it was on NZ Flightsim.
I found a great trim wheel at

It is not all that flash, you have to make your own mounting for it (which will hide most of it anyway) then just plug it in. It is so inexpensive that I doubt it is worth building one from scratch. For me it is just about at the top of my list of hardware as far as adding realism.
If you are still looking I hope this is of some help.
