Just a couple more comments on the thread. I have to chuckle a bit right now at folks nit-picking the cost of a sim as an adjunct to flying...having just written a check for a new prop for the 182.
I went thru the simming phases...joystick, then cheap Saitek controls, then bit the bullet and put something substantial together. I find many of the limitations on hardware are self-imposed. The Saitek yoke, for example, had about 90 degrees of total aileron travel, and +-4 inches of total elevator throw (fore/aft). The Redbird yoke I'm using now has the same 180 degree aileron 'twist' as the 182, and within a half inch of the fore/aft throw...11 1/2 inches if I recall correctly. It also has a nice spring arrangement (not force-feedback) that provides some 'feel'. Just like airplanes...you get what you pay for.
My philosophy on trim.... Ideally, you will never have forces on the yoke of an airplane, so lack thereof shouldn't be an issue in a sim. Each change in power or attitude should be accompanied a simultaneous change in trim, anticipating the changing forces on the yoke. Maybe it's just me, but it's just always how I've flown.
I've talked to the FSDO about certifying my homemade sim, and they'd be willing to do the inspection. Could probably get it done, but I'm fortunate that I don't really need to log the sim time. What my wife and I both love about it is what we did yesterday afternoon. We took turns hand-flying holds to approaches, using equipment that (as far as I have found so far) perfectly mimics the GTN650 in the 182. When was the last time you really did, or practiced, a hold in a complex airplane?
Oh...and we do it when it's too crappy out to fly.
