have you thought of developing an Aerofly-Version for Standalone-VR, e.g. Meta Quest 3?
I am currently using PCVR only, but I am dreaming of a VR flightsim I can take everywhere. An Aerofly-port would be perfect for this as it is extremely well optimised, has a perfect VR implementation and you also have plenty of experience with limited processing power from you mobile version. It would be a perfect fit.
