I tried to get as realistic flight sim as possible at home, using a HTPC linked to a LCD projector witha 7 foot screen. I use CH yolk and pedals, and Track IR to simulate head movements in the cockpit (MS2004). Also have the VFR scenery. It all looks pretty impressive, and friends who have seen it have been blown away. I stopped using it half way through my PPL, as I felt it did not compare to the real thing closely enough to help with landings etc.
I am giving it another go this weekend after a 6 month break, as VATSIM are having a fly-in.
I will probably use it for practice when I start my IMC course later in the year.
I just don`t get the buzz from it that I used to. Just need to make sure I do the real thing each week, and I`m fine.
