Still, for the most part it's a US plane in enemy paint scheme. I don't think HTC will allow it. Go ahead and ask 'em, though. Would be good to have a final say on the matter.
Japs might be able to copy things (jets specifically) but they had piss-poor engine copying. They would always put their own engines in. That would make it a different plane with different performance. The Soviet version, however, was most likely a C47 repainted (and some with a turret added)
