Also aggressively. Instead of flying away as with many planes do, fighters too, they return again and again for an attack.
The explanation is simple .
from Wiki:
"The F.K.58 was originally ordered to serve with AdA units based in French overseas territories. Following the outbreak of war with Germany, however, the type was assigned to an ad hoc, Free Polish air force unit commanded by Captain Walerian Jasionowski. Roughly equivalent to a French escadrille, or Polish eskadra, it was often known by the unofficial name "Eskadra Koolhoven""
I was referring to the way some AI planes behave. I am fairly certain that the behavior is encoded into the FM in some way or another.
For instance, time and again, I see that AI controlled FW-190s, an otherwise very aggressively used fighter in real life, seems to avoid attacking and keeps on climbing and trying to out-run and out-climb me (it usually works too). This kind of AI behavior is also apparent with quite a number of other fighters, P-38, P-47 and others.
In contrast, the FK-58 keeps on returning to attack, again and again. I've noticed this for other planes, a tendency to be aggressive, to attack again and again, to keep on circling my plane and never let up. This is more fun than trying to out-race a fighter and catch up with one flying away as fast as possible.
But i have no knowledge of how to change an FM, otherwise I'd have tweaked quite a number already.
But I am glad the FK-58 has the FM it does.
