Model 1704

The basic goal of this model was to create a modern Yo-Yo through artistic design using new materials and technologies.

This is an advanced full-size model for yoyo competition. It combines the ideal material of titanium and stainless steel bimetallic design to ensure a unique weight distribution, which is different from any other monometal yo-yo. As a result, the model showed amazing power and extremely stable spinning. It played lighter than expected.

The earliest design started shortly before Christmas 2016. After 6 months of design, prototype and testing, the final version has been released in the summer of 2017 and mass production has begun. The shape design of the model was inspired by the Bauhaus style. This style from Germany had a huge influence on modern design. It is designed with the simplest arc. The ergonomic profile gives a super comfortable grip.

The main body is made of titanium, which has high strength, low weight ratio and excellent corrosion resistance. This material is widely used in certain high-tech or special fields, such as aerospace industry and biomechanical applications. The price of this material is 30 to 40 times that of ordinary aluminum. Therefore, when cutting on CNC machine tools, it is more difficult to process than aluminum alloy materials, requiring almost 15 times the processing time. However, due to its powerful physical properties, the design of titanium masterpieces is much thinner than aluminum. Therefore, the thickness of the main body of REX is only 0.5 to 0.7 mm, as thin as 5 sheets of printing paper.

 

The outer ring is made of high-density stainless steel. The edge of the outer edge is very thin, only 2.17mm, which makes the entire yoyo seem to have a uniform thickness, such as a smooth curvature. When you hold it in your hand, it will bring you extra comfort. However, the rim accounts for more than 55% of the total weight and generates a strong rotational force. FWAE (fully wrap around edge) rim design has been described in previous models and has been used as one of the standard elements in my BiMetal yoyo design.
