P-39 performance after engine damage

[gaunt1]

Maybe P-39 behaves differently online?
Offline, I dont think that there is such problem. P-39 is one of the most vulnerable planes, incredibly easy to ignite. Did a little test, I flew an 1942 Hien (which has weak firepower), and I was able to set the P-39 ablaze even with one short burst 3 out of 5 times.
