That shouldn't work the Zero has no amour but the cat has lots.
After having played the game for a few days, here's my analysis:
Apparently the Russian planes like Catalina are made out of Stalinium and can't be destroyed by conventional means. Ramming them is the only way to be sure... aaaand actually, it's not. Sometimes they survive even that, so it's a good idea to carpet bomb them beforehand.
Unfortunately, crude Stalinium wing structure is no match for ancient Japanese plane wings, traditionally slow-forged out of finest tamahagane steel for centuries, as per the prophecy of the great war in which brave warriors would lead their metal birds to the battle, kept in utmost secrecy until the right time.
Basically what we see here is the clash of the titans, the materialized willpower of Joseph Stalin against absolutely perfect combination of iron, carbon and oxygen on atomic level interwoven with the spirits of the greatest Japanese swordsmiths of 2nd millennium.
Someone should really tell Gaijin that Japanese aircraft are actually made out of paper and that Russian wood is just as flamable and fragile as any other.
Actually Japanese aircraft aren't made of paper - Japanese aircraft were all-metal before many allied ones were, and were also very light and not all that fast....In terms of force-loading on a Zero, it's actually structurally stronger than most US aircraft of the early war.
People assume Japanese planes are fragile because they didn't have self-sealing fuel tanks and used to catch fire easily, but in War Thunder they're usually only carrying a very small load. Besides which, they don't tend to take many hits in game... the tricky part is hitting them. Late-war Japanese planes aren't actually much more lightly armoured than US ones.
And Russian wood IS less flammable and less fragile than other wood. It was actually a wood-laminate "alloy" for want of a better word: essentially wood treated with a special kind of plastic which made it stronger, non-combustable, stronger and rot-proof.
