Like I stated earlier, this software is "Ok", but nothing compared to the top of the line sims.

There are ways to use your own transmitter with this program. You can buy a cable to connect the tx to the computer, my apologies but I forget the websites. You can also make your own cable, but it takes some wiring/diagram/electrical component skills to complete. Going this route requires another free program called ppjoy(I think) to be able to recognize the signal. Check out the flight simulator forum and search for "fms cable" or something similiar for details.
