I am happy with my Oculus Quest 2 running RF 9.5 with usb cable in Lenovo Legion Y720 laptop. I fly 3D close fixed wing and helis and it looks amazing. You can't fly as far but I like the VR experience once in a while but not for too long. I mostly play on external monitor.
I got it to work with my new Lenovo Y720 laptop and Lenovo Explorer VR Headset thanks to your instructions. Thanks for sharing. I am amazed how cool this is.
Make a new plane model in your radio and don't make any changes. Use it for helis and planes in the sim. In RealFlight go to Simulator, Select controller and Edit. There you can monitor the output from your radio and set up the simulator. If you can set up a plane you'll know what to do...
