I was just finished a post on another topic where I said that we really need study level birds!
I own the Hotstar TBM in Xplane, sure that if we talk about realism, there is two world Xplane and MFS2020 default aircraft however we have to admit that the default xplane birds are not really genuine, hopefully A2A simulation will come soon, same for HotStar!
As for a study level GA, the SP-30 (very very study level) will come soon in MFS2020 for information. Can’t wait!
