I keep getting tempted with a Warthog setup.
I have the Logitech X56 Rhino at the moment but I am getting "Phantom Button" presses so I need to sort that out at some point.
Played a bit of Elite Dangerous again recently, it's has made me want a VR headset again but at the moment a VR headset is way down the list of "things I need".
Those VKB's are supposed to be really good though, will be interesting to see how you get on with it.
are you using a powered hub for your X56? phantom buttons and straying hat switches, are a symptom of plugging the hotas direct to PC. If you use a powered hub, this issue tends to go away. I think the X56 needs more "juice" than what gets supplied from standard 5V/0.5A usb ports
