A simple reference to the source that you, the CloD developers, took from and modeled this information into the game would be all that is needed to assuage the raging frustration from players...or just simply state that you "have not created a flight simulation, but a representation of a world where the WWII aerial theater never happened as it did."
This is getting ridiculous.

Now to put these sort of posts hopefully to an end, here is the flight model and engine model from an aircraft in IL-2 1946:
And yet Oleg himself stated that the models in CoD are calculated at many many more points, and these calculations are also more complicated...

And then we can take a look in the java files, and we have a plethora of calculations that all work together, this one being a rather simple example for engine inertia:
Code:
public void setFricCoeffT(float f)
{
fricCoeffT = f;
}
private float getFrictionMoment(float f)
{
float f1 = 0.0F;
if(bIsInoperable || stage == 0 || controlMagneto == 0)
{
fricCoeffT += 0.1F * f;
if(fricCoeffT > 1.0F)
fricCoeffT = 1.0F;
float f2 = w * _1_wMax;
f1 = (-fricCoeffT * (6F + 3.8F * f2) * (propI + engineI)) / f;
float f3 = (-0.99F * w * (propI + engineI)) / f;
if(f1 < f3)
f1 = f3;
} else
{
fricCoeffT = 0.0F;
}
return f1;
}
private float getJetFrictionMoment(float f)
{
float f1 = 0.0F;
if(bIsInoperable || stage == 0)
f1 = (-0.002F * w * (propI + engineI)) / f;
return f1;
}
So take all of that, complicate a few times and this is what the devs are dealing with, the 3d model has no effect on the flight dynamics. So I am sure you can imagine just what they are working with here.
