I couldn't easily trim the Spitfire
That is actually realistic. Welcome to neutral stability!



I tried it as well and found it extremely difficult to hold at a consistant climb speed. That is neutral stability and why the aircraft is a two fingered airplane. The airplane required very little trim input to achieve a trimmed condition as a result. Unfortunately, it harder to do that with a computer joystick as we don't have the "feel" of the airplane.

What I thought was unrealistic is the oil temperature rise. I could not get the Spitfire to decrease oil temps satisfactorily.

My oil temps stayed around ~85C in level flight at cruise settings with the radiator fully open and very quickly ran up against the maximum of 90C in a climb.

Running that close to redline in level flight is a squawk and it would be investigated to be fixed.

Granted it is summer time but with the exception of taxing, the temps in the summer never get that close redline at cruise settings.

OK, just some more spare time rambling to indicate we don't have a standard day and we don't know why it changes between servers. Or why Farber's wingman's altimeter reads different to his by 200m
I really think this the biggest issue. We have inconsistant evidence of atmospheric modeling. Temperature is above standard and pressure below standard. That is consistant and our density altitude should be high as per summer conditions.

What is not consistant is the variation in elevation as I assume pressure on the 200 meter altitmeter readings and most disturbing is the FTH is not consistant with a higher density altitude.

If the FTH matches standard day data by occuring at the same standard day altitude, the Flight Model's reaction to the atmospheric model is porked.
