BRs will work, as what they have done to F2.22.2.
All planes should have more detailed damage models. They could model internals and the aircraft structure with a lot more detail. With current damage models plane fuselages are modeled as three or four large pieces and each piece has a single durability value. In larger planes each piece is almost as large as an entire prop fighter, so we have things like tails detaching in a single cannon burst.
Not a fan of the idea of buffing gunners, though. They’re already deadly enough in sim.
From my pov this has other reasons.
I recommend to look for posts by this guy: @DerGrafVonZahl .
Even admitting that he comes often along as smart ass (and sees Sim pilots as pinnacle of human evolution) he posted a lot of rather good (to very good) analysis of why and when certain things were implemented.
So regarding tails:
Have a good one!
