4.12.2 de-bugging

[Mabroc]

I always found it funny that P-51, P-40, Bf-109 got damaged engines with overheat and loss of power when hit or instantly died with a good burst of fire but the P-39's have no noticeable loss of power and usually can fly 10+ minutes at full combat capability smoking a lot.
Even when they have almost the same engine and amount of oil than a P-51 and P-40, lots of oil tubes around the engine that you easily perforate meanwhile doing other damage to the engine from a 6 o clock firing position.
