i played a demo of a-10 cuba and USAF a long time ago...i'm not a pilot myself, but i read real manuals. I think a-10 cuba was somewhat ok...
USAF was more arcade though. The a-10 has a radar and it's clearly overpowered. Most of the cockpit functions are not there or not realistic.
I personally prefer falcon4. The new 'Superpack3' mod is amazing, and it allows you to fly the hog with a free-ware pit
(i recommend 'aeyes'). It doesnt do a great job modeling the a-10 flight-model or it's functions, but it comes closest to the flight experience. It's still more of a F-16 sim, but a great one at that, i read some of the F-16C Blck 50/52 manuals to get it right, alone the engine start-up takes about 7 minutes (even longer to calibrate the INS and manually store VIP/OA/VRP-Points).
So i don't think there is any real realistic sim out there for the a-10.
But LOMAC and Falcon OIR (if it finally overcomes the problems) are in the works and look promising...
By the way do hog-drivers use VIP/OA/VRP, too? Would make sense, but i wouldn't know on what 'computer' to store them
