I don't mean to be rude, but yes it is. There is a section in the manual describing Joystick headings and assignments. You'll need to open the FS9.CFG file and determine which joystick heading is linked with your TQ-6. It took me a while but it is possible. After determining the correct heading, you then need to manually set the assignments.
After that is complete, FSUIPC will recognize the TQ-6 "in the correct place" The TQ-6 functions just like a game controller. Make sure you have de-selected ALL assignments in FS2004 before trying to get it to function correctly. Be sure to follow this order...
After opening the assignments page...
Click on the AXIS SETTINGS Tab
Click the NORMAL FLIGHT radio button
Click the DEVICE (TQ-6)
After deleting the fowling assignments Click OK.
FS2004 has the tendency to add assignments. If you don't click OK after each set of changes, you may have problems. Meaning, after changes to my yoke, I click OK and go through the process again for my Stick.
Hope this helps... Pete?
