Different from many other 450 class helis, this V450D03 uses plastic materials instead of metal, someone might question it`s toughness and durability. Actually, it`s really no need to worry about this. The plastic material is no ordinary, but special Carbon Fiber Reinformced Plastics, which makes the heli very strong yet at the same time very light.
