Ok, The Z-21 looks like someone tried to make a Apache out of a black hawk frame. Makes sense from a logistics standpoint as the AH-1 cobra series of helicopters came from the Huey frame. Aesthetically it doesn't stand out from its competitors with isn't saying much as attack helicopters typically look ugly. Still curious as to why they decided to create this helicopter outside of reaching the 10t limit, it just looks very box standard design with little indication of innovations.
