On the same day I have asked this question:
I got an answer on the same day I posted. It was a good answer.. I accepted it. Many other people liked it as well, since that answer got so far 47 up votes.
Couple of days after that, someone else posted another answer, even more comprehensive and specific than the first, and to the exact aircraft model that I was referring to in my question, the Focke Wulf 190, the answer even contains a link to further details in the design of the aircraft in question and brings up other details like the way they kept the ammo for the machine guns heated with the heat of the engine, etc.
Should I change the accepted answer?
There are penalties on doing that, and I don't want to pay.
