The RAH-66 was a stealth attack helicopter prototype, which was cancelled due to high cost and other factors.
This mod was made a long time ago, I just got over myself and polished/finished it up right now. The model is kinda undetailed in some places, but to be honest, I didn't want to spent more time on this.

Mod features:
Middetailed model
Middetailed interior
Working suspension
Enterable for 2 persons
Breakable boot
Bullet impact
Custom spec map
Working lights
Custom LOD models
Custom Collision model
