BACK TO THE ORIGINAL QUESTION!!

I have RealFlight classic (the first one they came out with and the Tx that plugs into the printer port). I am flying FMS with no problem. Orginally I got it working but had no rudder and then I figured out that I had to customize the controler in the add menu. Here is how I did it:

1. Plug the Tx in
2. Go to My computer
3. Go to control panel
4. Go to printers and other hardware (or if you have a different version of windows it might give you the option of going on into step 5)
5. Choose Game controlers
6. Hit "Add"
7. Click on "Custom"
8. Select "Race car controler"
9. Where it says "Axis" then type in 3
10. Where it says "buttons" type in however many buttons/switches that is on the controler
11. Name the controler FMS or something you will remember
12. Now remove whatever controler that you have set and make the FMS controler active like you would any other joystick or Tx.
13. Calibrate that bad boy (it might say "move the wheel around" but just calibrate it as if you were calibrating RealFlight).
14. Go into FMS and pull down the "controls" menu
15. Select "Analog control"
16. Select "Joystick interface"
17. You might have to activate it by clicking the switch in the mapping and calibration section.

NOTE: Fly the airplane but some of my sticks were backwards. Figure out which ones are backwards and go back to the mapping and calibration page and fix it by assigning which channel goes where.
