Differences between bf 109 f-1 and bf 109 f-2

i just unlocked bf 109 f-2 as axis in moscow and it turns out that its parameters after max upgrade are inferior to the f-1 unlocked earlier

weaker armament, slower, worse climbing and turn rate
the only thing thats better is amount of ammo

also i have one unupgraded il2 and golden order il2 and the golden order is slower have the same turning rate and 1m/s better climbing

my question is is this supposed to be that way or is this a bug? or are there some hidden parameters that are not displayed? what is the point of that

F-2 should have almost identical flight performance to the F-1, and in my game it’s identical, you should restart, it should fix the issue

ok its identical after restart, so the difference is armament only, right?

Yep, it’s the only noticeable difference

thank you for answer
