I have the original Oculus Rift. The HOTAS I use is the Thrustmaster T.16000M Flight Control Stick, TWCS Throttle and TFRP pedals.
I have Ultrawings as well. I have only played Ultrawings with the Rift controllers though which is the thing I do not care for. It just does not have the same feel without the HOTAS. Although, the downside of the HOTAS is getting everything programmed and talking to each other nicely. That can be frustrating at times. Not to mention the setup required. I just use my office chair and a small table to set everything up, but it is a pain and takes over your living space unless you have a dedicated area for it.
It is worth the extra setup once it is all working though.
I could geek out on books as well, but I have done enough of that in this thread already.
