those lavochkin fighters sure are nasty.

The setup, I'm flying fighter bomber fw190a8, after having struck targets with bombs. So, I have the bomb-rack making some drag.

La7 (it's a 1944-45 Russian fighter) is a monster in IL-2 sturmovik basically. Huge speed, excellent turning and rolling ability, adequate firepower to destroy anything, but it might have less ammo (not sure)

La5FN model is sort of the same deal except that its characteristics are somewhat worse than the later La7 model.

Is there anything to be done really, against La5fn and La7?

It feels like flying a wildcat against zeroes, or somewhat similar. Those Russian fighter sure are dangerous and it seems that any mistake will be easily capitalized by them. (because they have such good engine performance, they are like "semi-bnz" aircraft)
