I used to fly a lot of Falcon 4 AF, and now I'm getting into DCS A-10... so far it seems to me that the avionics and systems in the A-10C are a lot more complicated, and it doesn't even have a radar to deal with. There's a lot more crap on the HOTAS for one, yet I could easily and quickly operate all the F-16 systems on the Cougar HOTAS. It's likely that some of that is caused by DCS modeling the systems with more fidelity, but I don't know. I still need to finish reading the manual and doing the tutorials to boot.
