It truly is a shame. The plane was great in P3d, and I was enthusiastic about it in MSFS early on, figuring (based on dev comments) that it would eventually reach P3d level as a high-fidelity-systems rendition of the plane. Nixon is right though; it seems to be abandonware at this point. The P3d version was clearly a labor of love for someone; unsure if they lost that dev or what… but it’s currently in what I would call a beta state at best (unmodeled systems, non-functional engine instruments, flight model problems, barely functioning gyropilot, bugs galore) and has received no fixes in, what, a year?
I’m an absolute historical fanatic for this plane, but at this point even I feel like I wasted money on it.
