You can also download the beta of this one for free for a bit of fun - but the devs have said it is in early beta and not even vaguely close to ready — so do not download if you expect anything like a finished product
The cockpit is not modeled yet except for the Garmin G3X and some switches. The gear/pilot/etc. are only rough placeholders and there is the known bug, that it sometimes starts with empty tanks (refill via the menu). The fligh model is not yet accurate and textures are mostly missing.
