Sponsors and Curators The Museum of Yo-Yo History is a labor of love, and we would not be able to stay up-to-date with exhibits without the support of our sponsors and curators. Big thanks go to One Drop Design and Duncan for supplying us with their latest models, YoYoExpert for their help and support, and to Cody Orr, TotalArtist and YoYoBrothers™ for allowing us to use their collections! If you're a manufacturer, or just a big collector and you want to help support the Museum drop me at line at chimera@yoyomuseum.com YoYoJam SpinFaktor HG XTra Exhibit #1208 Type Special Release Shape Concave )-( Axle Bearing Color Red & Black Packaging Boxed Construction Multi-piece plastic Response O-Ring/Starburst combination Diameter 2 3/16" Dia Gap Adjustable - Twist Weight 80 g Estimated Value $65 Condition Mint in Package Date 2005 Owner David Hall Compare The SpinFaktor HG Heavy Gravity featured rim weighting like YoYoJam's composite body models, but was an all plastic model. The rim plastic was made much denser than the rest of the yo-yo by adding heavier particles to the mix. YoYoJam released these in fall of 2005. They were part of a limited test run, and only about 80 were made. The HG XTra is the same shape and size as the standard HG, but was much heavier.
