If i am correct, the changes mostly effected the aircraft in the areas of drop tanks,rocket rails and bomb equipment. Even if the Aircraft itself doesn't model the code by eye candy, the effect* is still there. As in, even loading a bomb or DT will "add" that component to the plane, as in increased drag on the drop tank,and rails..as well as weight. Without or without the component being dropped, even if you drop your DT, even having the shakles for it ad's drag and weight. how much? test and find out.
I found my P39Q without .50 gondolas & Dt removed can get better range with constant engine management "and better speed" then it ever could with the DT. Figure that math out.
If i remember the it correctly.
