Man, I want to.
Its wierd to see hard 3D work go into a sim. Its like bringing technical drawings to life and getting to fly in it. Putting a plane into the Virtual skies of XP would really be interesting for me. I am a detail nut, so having all the things in the VC in XP would be interesting for me to see how they would display.
I am thinking they do not have a 4MM weld limit distance, which will enable me to make far more detailed parts in the VC's, which FS9 cannot do.
