And a few more WIP flight models for the mossie.
1.) The "Tsetse" FB Mk.XVIII, essentially an FB Mk.VI with a 57mm molins "6-pounder" gun.
Blue=New, Red=Old. You will notice major differences, which is because the old engine model was completely off.

2.) The NF Mk.II - similar to the FB Mk.VI, but with older Merlin 21 engines (Merlin XX with reversed coolant flow) and radar antenna on the nose (little drag added). Blue=New, Red=Old.

3.) Comparing the Tsetse (blue) to it's base model, the FB Mk.VI (red).
Note the difference in turn performance and in ROC, but similar top speeds.
Reason: Engines are the same, drag is almost the same, but weight isn't. The Tsetse carries more than a ton of extra weight due to the Molins gun (655kg extra) and additional armor (410kg extra).

4.) Comparing the NF Mk.II (blue) to the FB Mk.VI (red).
You will say: What? A fighter is slower and turns worse than a fighter-bomber?
Yes. It's all about the engines. The Merlin XX is on par at altitude, but has way less boost and easily lacks 300 horsepower on deck, which is why the (sustained) turn performance @1km altitude can't keep up with the later FB Mk.VI, simply because the Mossie bleeds more energy than the NF Mk.II's Merlin 21 engines can retain.
