@RulingPen63350, it’s simple. Just as in real life, it’s much more difficult to create a study level 747 than it is for a 172. And I don’t know what 787 you paid extra for, but I’d be money it’s not a very good one. Maybe better than the default, but nothing like the real beast.
As for fair, it’s like my pappy used to say (often!)… “Life isn’t fair!”
