As many of you have probably seen, the X-Plane 11 public beta just started Before you go and update, know that it is not compatible with FlyInside XP. There's huge graphical stutter, non-functioning features, etc.
We plan to release support next week, it just isn't ready as-of-today. Feel free to try out X-Plane 11, it's an amazing simulator! Just don't overwrite your X-Plane 10 install just yet, especially if you want to keep using FlyInside.
UPDATE: As always progress is slightly slower and more difficult than expected We have some very good things going on (Leap Motion working with new FMS, auto-pilot controls on stock planes), but also some unexpected challenges involving graphical glitches. As fixes come together, we fully expect to launch an update sometime the week of 12/12
