Not only are they carbon fiber, but they were the coveted V2 V blades. Man was that one a sight. It went in full speed, knife edge. It was a Vigor CS, and it must have gone almost 20 yards before it found its resting spot. Which is right where the flowers are. Surprisingly enough though, the damage wasn't all that bad. The machine is already fixed. Of course that may be because the pilot owns a hobby shop. But still, I was surprised that it didn't get totaled.
