I would say that the problem goes just as much, if not doubly so, for Soviet aviation, minus the popularity of the La7 and Il2 for obvious reasons.
Soviet aviation is the most "dissed" big player in the game. I know, I know "skin the Lend Lease".

Boy is that getting old.
I think a major factor is deciding to model an airframe, not that anyone cares what I think, is that players should actually want to fly it. But also Modeling based on player votes alone is a mistake. Didnt WW1 teach them anything?
