I have noticed a realism issue with the model of the UH-1Y Crash Site in the current build. The main rotor blades appear to be frayed as if made out of fiberglass or something. In reality the Main Rotor Blades of the UH-1Y Helicopter are not made from fiber glass. They are made to compartmentalize and not fray. I'll include a picture to show what they look like after a crash.

The UH-1Y features four-bladed all composite, ballistically tolerant main and tail rotors. The rotors can sustain a 23mm round direct hit The rotor design has eliminated all bearings, hinges and rotor-mounted vibration absorbers. The blade body consists of a spar assembly, leading edge protective strips, skins over a honeycomb core and a trailing edge strip. {F32183}
