You were pushing it too hard waaaaay out of its limits and it has 0 efficiency in a dogfight.
I'm talking about speeds constantly used in a dogfight. In DCS's Bf, the stick forces come into play @ speeds as low as 250km/h IAS whereas the pilots said that after 700km/h IAS the controls stiffen, which is normal because at that speed comes the compressibility, for ALL of planes..
