I'm lurking. Very interesting things here. I say only this: you can (must?)
change the models D.520 and IAR 81M production to model Bf 109Ga-2 or Ga-6;
because this sh*t of airplanes can upgrade only to other few model, and the
better is in my opinion the Ga-2. You can (must?) change the italian model
production to other best fighters (really, the MC.205 Veltro, the G.55/I
Centauro and the Re.2005 Sagittario are good fighters compared to Bf 109,
but you can produce they in little quantity, because they required 2xengine).
About the night fighers, in my experience (vs IA) the Ju 88C6 and the Bf 110G4
(or Bf 110G4/M1) are the best initial models (the best...he shot down 1 bomber
of 100, but the others models are worst). Sorry for my poor english, and if you
have more production info, share it!
PS. the Fw are good planes, but more delicate than I thought, even if used under
20,000 meters, in theory their best maneuver band.
