Soviet's P-39

[Avimimus]

As for the early Kittyhawk/Tomahawk (P-40) versions - they also sometimes deleted the wing guns to save weight... so the armament was two 0.50 cal mounted on the nose. I modded in this variant at one point - and it was fun to fly.

P.S.
We could also do with providing options for the Ar-234 to not carry under-engine bombs (in reality they often flew with only the centerline bomb - and sometimes with the 20mm guns removed in order to make them faster and harder to intercept).

Also, something like 2/3rds of the P.11c's in service had no wing guns... so for realism in the Battle of Poland we need the option of deleting those guns.
