I’ve reported visual bugs for helicopters. I’ve seen models of helicopters not even be correct. Rotors don’t actually have collective, when rotors are still and collective pitch is changed, no angle change is visible. Rotors aren’t given their own rotating polygons per rotor, and are invisible to air radars.
I know helicopters are only a small part of vehicles in this game, but they are a huge part of it. I just wish gaijin would properly fix their not only buggy modeling, but straight up improper modeling, and fix things that should have been ages ago.
