Cestrosphendone fail

This cestrosphendone dart did not fly well from the sling. Its balance point is too close to the center of the shaft, and so it takes too long to stabilize after the gyrations of the launch. The original dart described by Polybius was very point heavy, and such darts perform much better when launched from a sling.

Recorded at 300 frames/second with a Casio EX-F1
