Ah, the Warthog. Got mine while I was waiting for Premium Beta to be released and then trained myself on the combat scenarios. Though I have switched my config around a few times. As others have noted, the switches on the TQ are not momentary (well, most of them) so you have to flip on and off to trigger a button press into E

, but that can be sorted with TARGET (sort-of, I think, I just put up with it).
For those who find the stick a bit stiff - and apparently it has more or less the same force as the real A-10 stick, all I can say is that Warthog drivers clearly have strong arms - there is a mod you can do that involves removing the main spring and re-using the springs that hold the base plate to the ball for tension instead. The stick moves much more easily, and I personally found that much less tiring on the muscles, so I've stuck with it. But it's non-destructive and you can keep hold of the spring and put it back in later if you want. It does make the stick less self-centering, though.
I use the Saitek PRO Combat pedals, the pedal assemblies are metal rather than plastic and they're much more sturdy. I own multiple pairs of CH pedals and I much prefer the Saiteks.
