Hi:
A bit OT, but there are many quality add-ons out there for FS9 right now, so I recently performed a "Mid Life Update." Here are some pics:

Enjoy!
I think this is not a matter of importance... an airplane gots stick, throttle, rudderpedals and toebrakes and airbrake(axis or button in fighters? I don't know)....
I consider it a minimun requirement (as Micorosoft did). Then add all you important features and a good afm, then put the product in the shops...
Now it looks more like a puzzle where everybody ask for pieces...
