Hi Flagada Jones,
I use TrackIR under FS2004 since 6-8 months and when i saw that a Vector Expansion was sold, i bought it for playing with Flight Sim 2004 and future versions. And when GTR (race game) will be release in france, i will play it with TrakIR and i hope VE too !
As there are problems with software v4, i couldn't test the VE yet...
Regards.
