This diabolo shares the same wide axle bearing as the standard Fly, but has a counter weight and rotating tip instead of the second cup.

One Way Axle rotation can be switched for left or right handed play or for Eastern (start with cup side nearest your body) or Western (tip side nearest body) styles of play.

This one sided diabolo is not meant to be balanced and the diabolo will turn with play. This is intended and is in keeping with the traditional Chinese Yo-Yo style of play (but with a modern twist of the bearing axle)
