The team, that recently returned to active duty, has been slowly updating their older models. This time it was the turn of their BK-117 which you can now enjoy fully in both FSX and P3D.
According a post on their Facebook Group, “it can be installed for FSX/FSXSE and P3Dv4” and users can get the latest version at the official website (meaning the update should be free for those who already own it).
