New octagonal table tennis racket, using the length and angle of the 9 sidelines of the racket, changing the sweet spot caused by shifting the center of gravity as the basic design concept, enlarging the sweet spot into an oval shape, with a high error-tolerance rate to improve the scoring rate, and the center of gravity Deviating to the top makes it easier to exert force, and the centrifugal force is multiplied, making it easier for beginners to master the feeling of hitting the ball. [Comparison of octagon and hexagonal rackets] The hitting area at the top of the hexagonal racket is enlarged. In addition to the sweet spot to increase the fault tolerance rate, the adjustment of the center of gravity to the top is a good speed-up change. However, the test of the hexagonal racket shape is in front of the racket when attacking close to the table. The second corners on both sides are easy to collide with the tabletop, and are only suitable for powerful arc attacks from mid-range and long-distance platforms. The octagonal racket also has its center of gravity and sweet spot adjusted, but the octagonal racket with this structure has 2 or 3 front ends. The end face between the corners is parallel to the tabletop, reducing the hitting point of the forehand and backhand near the table, which can take into account the change of the center of gravity to the top and the characteristics of the fast break near the table and the force will not hit the tabletop. The same performance is improved in the middle and far. The power of the attack and the evolution of the fast attack function near the station, 【ORCA 8 Racket Features】 The top area is increased by 14%, the sweet spot is enlarged into an oval shape, and the oval sweet spot extends to both ends of the racket to improve the fault tolerance rate, and the goal rate is increased by more than 20%, making it easier for beginners to master the sense of hitting, and for advanced hitters. Easily improve the scoring rate and improve the spin and speed performance of the shot. The center of gravity moves out to the top. Due to the increase of centrifugal force, when you hit the ball, you can swipe a little backwards, and the response is more accurate, and the hitting force can be easily exerted to produce strong explosive force. The ORCA 8 ALC carbon fiber racket is designed and manufactured with the same material of Butterfly King Japan. And the speed can be more incisively and vividly, the octagonal racket surface increases the sweet spot of hitting the ball to avoid the instant explosion of the carbon fiber racket and uncontrollable. In the future, a series of different material rackets will be tested one after another to make playing Table tennis another kind of fun--- ---.
