That's nothing... The Italian planeset has only 2 planes, and both are different versions of the same airframe!
The Japanese are missing the betty bomber, the germans are missing an early bomber, a heinkel, and maybe a dornier or something. The Brits are missing EVERY bomber they had, except the lancaster. The americans are missing the light b-25 (glass nosed, PLEASE, no more hard nose stuff!) bomber, and there are lots of planes that are missing.
The russian planeset as it is has a lot of monsters. Historically it was full of flops. I'd like to see the flops put into AH, for scenarios and setups. Mig3, etc. The ones that were failures, and inferior. That type of stuff. It would round out the fighters a lot. I'd also like to see a few bombers, but that can wait.
