About
The AstroFly is a 2013 intermediate string trick model in the third Hyper Yo-Yo lineup. It features the UFO-type (Center Trac) bearing specifically to keep the string centered on the axle for improved stability during tricks. The weight — 69.6 grams, one of the heaviest plastic string-trick models in the lineup — was intentionally increased over comparable models to improve spin times. Requires double-wrapping the string around the bearing for responsive return; intermediate players who have mastered basic string tricks will find it the natural next step after the GalaxyFly.
