Thanks for the detailed info.
I know the version for Xplane from FliteAdvantage. The GPS worked pretty good and we could enter custom waypoints as we used it in the actual aircraft.
But if that works also in the BB version (and what you say, it seems like that), that would be a good pick.
I didn´t read anything about the 38A or 38C, but I think it would make more sense for the company to focus on 38C as long as the USAF/NATO is using them for UPT.
