Fly-wheel effect

In Beyblade terms, the fly-wheel effect is an attribute of Stamina, that refers to an ability all Beyblades carry during spinning. More specifically when a Bey spins, less air is pushed back on it to try and slow it down; thus, the Beyblade spins to it's fullest potential.

By definition, the fly-wheel effect is of reduced air friction (more streamlined) of a Beyblade; spins in the air with the least back draft slowing it's spin velocity.

But as stated above, the fly-wheel effect simply put: when less air is pushing on the Bey and maximizes their spin.

Generally, all Beyblades are capable of the fly-wheel effect, but it works best on Beyblade with thin, round Fusion Wheels; stream-lined Beys with flat surfaces. A few consist of: Fusion Wheels with various protrusions, bumps, and curves such as Variares, Blitz, and Diablo are still capable of it. Yet, it will not work as efficiently as with the aforementioned Wheels above. The reason being, take Variares for example. With all it's dips and ridges, air flow would be caught in those and as a result, take a loss Stamina severely.

Overall, the fly-wheel effect is an importance to Stamina-Types. It's effect can give Stamina-Types an advantage in battle with round and circular Wheels. Although it does not work as good, as on Attack-Types (namely Variares), each Beyblade is capable of it, in order to increase it's Stamina.
