P-39 performance after engine damage

[The_WOZ]

I have talked about this on other thread, a few planes in the game lack a 3D damage model, among those is the P-39 and Ju-87 families.
In these planes internal systems damage is calculated at random when a bullet hits the fuselage.

The P-39/63 have two oil tanks, a big one on the rear for the engine and smaller one in the nose for the propeller shaft reduction gear
