I downloaded the newest version from Cubabnaces facebook page. As of now, it is a bit of a toss-up regarding whether or not this mod properly works in Open Beta in my opinion. For one, it can still occasionally cause the mission editor to glitch out and require a complete restart of DCS World, (Note: this is also produced in 2.7 Open Beta by the A-29 Tucano mod also, so I do not fault this mod completely for this problem). Also, though it does work in missions, certain flight-envelope/air combat maneuvering situations in which the AI is piloting the aircraft will cause it to become frozen upside down in mid-air. After which it slowly descends towards the ground upon which it crashes like any other failing aircraft. I really do love this mod, but it is still very buggy from what I can see. I hope that it gets fixed to the point that these bugs stop inhibiting my use of it in missions as I would like the F-22 mod to have proper competition besides the poorly textured J-20 mod.
