I don't own the Warhog either, but from what I've seen and herd about it, it looks like it's great for modern jet simulation especially DCS-A10C obviously which is what it was made for. I imagine it might be pretty good for Black Shark and Flaming Cliffs 2/3 but the issue really is when something becomes so specialized it is bound to lack in other areas. I love the concept of having a realistic sim pit representation of an actual aircraft however in practicality its definitely not ideal. I find that in practice it is much better to make things that are adaptable or universal especially if you are the type that flies more then once sim let alone plane. What your basically left with is making your own mishmash or controllers both production and custom.
Don't get me wrong, it would be awesome to have a sim pit for several different planes and then maybe a universal one as well but I personally can neither fund that nor have the time/room for it. There are a ton of guys on the internet with replica pits for A-10, Blackshark, F-16, Bf109 and Spitfires just to name a few and I find them simply wonderful. If I could own one of each with the addition of a custom universal pit I'd be like a kid in a candy store however its just not practical. I mean if all I did was fly DCS-A10c exclusively then why not, but the reality is, like with most of us, I fly all kinds of sims, let alone planes.
If I have an extra 500 bucks and nothing else to spend it on I'd get a Warhog, but like I do now, I'd be swapping it out every time I switched sims and there are a few other bits I'd like to get before then like a touch screen for example. As it stands I'm spending too much time with IL-2 and ROF to warrant getting DSC-A10c let along a specialized controller for it. Now when Flaming Cliffs 3 comes out, I will probably be more onboard with the DCS series although even then I don't know if I'll be looking at a Warthog anytime soon. It looks like a well made controller but its a really shame there is not FFB to it. The Logitech looked so promising but I've herd a lot of negative things about it and I'm just not convicted of its performance or usability.
Just my 2 secs, its a very interesting conversations and I love talking about controllers.
