Hey guys,
Been "lurking" for quite some time now, and finally found a subject I actually have some Knowledge of. As 58skylane mentioned, Rudder Pedals are an important part of learning how to fly, since most if not all aircraft also have them. When I was working on my PPL, I purchased the Saitek Yoke, Pedals and Throttle to use with FSX. I have not used the CH version and can only speak for the Saitek product, but either will do the job of giving you an almost realistic flying experience even when you can't be in the actual aircraft.
I think my time spent practicing on my simulator ultimately helped keep my overall cost of instruction under control, as well as gave me ample opportunity to work on XC, diversions, pattern work, etc.
Now that I'm finishing up my commercial and instrument and moving on to CFI, I still make time to work on holds, approaches, ito's, etc. on my simulator, which will only help keep costs down, and give me much needed experience, making me a better pilot when I'm in the real aircraft.
The only other thing I will highly recommend to go along with your flight simulator is a book by Jeff Van West and Kevin Lane-Cummings which has helped my simulator training. Its called Microsoft Flight Simulator X For Pilots: Real World Training and can be found at almost any book store.
Not sure about the earlier versions of Flight Simulator, but FSX has Johnson Creek, and last week I got to land there for the first time from the relative warmth of my home office in the winter.
