I have been using this plane for the last week or so and have made some observations about its performance.
The Ta 152H Höhenjäger ("high-altitude fighter") has Service ceiling of: 14,800 m using GM-1 boost (48,550 ft using GM-1 boost), I am assuming GM-1 boost is WEP.
When in training, on realistic, with the Ceiling set to max (9,000m or 30,000ft), this plane suffers maneuverability and climbing abilities.
When I pull back on the stick, the plane barely moves to a 15 degree angle.
Roll rate is much slower, by at least 2 seconds and the turning rate is slower too.
In fact I find that I have best handling and climbing rates when at the altitude of 15,000 ft.
But, DANG is she fast.
Off course this is in BOP.(I also know its only a game.)
Note: Also, for all the haters, she is not just like the Fw-190 D-9, the Ta-152 has a longer nose, plus she has larger tail fins and did I mention that she is really, really fast.
