I still fly the -300, have hundreds of hours on it, it is still the best feeling aircraft to fly, way better than anything MSFS has to offer, better feeling than Zibo and is a nice challenge with it's limitations. Really enjoy the Felis 747-200 for the same reasons, it is completely manual VNAV and INS system, IXEG is like a Tesla compared to that dinosaur!
More than willing to pay for an upgrade to XP12, of course we have waited a long time for an upgrade for XP11, but the developers have been very transparent with the reasons for it not happening, which is totally acceptable. If it was to happen for XP12 then that would be a stroke of fortune and good timing, since the team have found some time to put development work into it.
