X-Plane 11 VR is how!
Though I'd still rather fly Aerofly whatever the controls.
I've watched a couple of XP11 VR "Hands" videos on YouTube and I'm still not sure about the use of the Touch controllers. Having to hold a separate controller to represent my hand means I can't be using that hand to interact with my real-world yoke, tpm, etc.
I'm an early adopter of the Leap Motion sensor too and have had it stuck to the front of my Oculus since day one. This I can see potentially working very well as long as the tracking is consistent. I could let go of my physical yoke, reach "up and out" into the virtual space to touch virtual controls, etc. Could be good.
Either way, I'm looking forward to what the IPACS team brings us. I'm certain it will rival if not better the competition...
