Not always so.
If the airflow is modeled to the mapping of the 3D shape, and that 3D shape is suddenly remapped in radical new ways, would it not follow that the airflow has to be re-mapped to the new geometry?
I'm not sure it works that way, I'm just saying HTC has been taking the time and effort to "re-map" the flight model to the 3D model when it's upgraded. The damage model is remapped as a necessity, as bullets hit the 3D object and that tells you where damage is applied.
The N1K2 doesn't feel like a Zeke anymore, the La-7 doesn't seem to pull as tightly as before, the 262 was utterly nerfed (no more mushing through stalls for under-nose snapshots -- the only move this plane used to have), F6Fs feel less responsive, and a couple of other issues.
Mind you, all minor stuff that many players don't notice because they never fly these rides. I'm not thinking it's intentional per se (except the 262 change!), just side-effects from re-mapping the flight model onto the newer 3D models.
Sometimes you don't notice much change (Ta-152), but sometimes you notice a lot.
