Li-Ning Aeronaut 9000 badminton racquet is built on the Aeronaut Technology Platform with a unique air-stream channel integrated into the racquet head. This reduces air resistance which helps to generate faster shuttlecock speeds. It’s suitable for players looking for the best control with little to no sacrifice in power. The AERONAUT Technology Platform in the racket uses a 4-digit numbering system. The first digit determines the grade of the racquet as follows: If the first digit is 1, 2 or 3, the racquet is suitable for beginners. If the first digit is 4, 5 or 6, the racquet is suitable for intermediate players. If the first digit is 7, 8 or 9, the racquet is suitable for advanced players. Technologies used in the racket: Wing Stabilizer: Introducing aviation technology to control the Racquet frame. After impact, Li-Ning racquets absorb unnecessary shaking from vibrations and restore the Racquet’s outer “wings” back to a precision performance mode. This readies the player for a quick, precise, and stable follow-up stroke. MPCF Reinforcing Technology: Li-Ning takes the extra step to avoid imperfections sometimes caused by machine processing of other racquets. The racquet is crafted with strength and longevity by implementing multi-layer carbon fibers. Dynamic-Optimum Framed: Li-Ning racquets are manufactured with a sweet spot that extends upward. The hitting point is moved higher, providing a larger defensive area. This considerably improves hitting velocity due to a broader stringed area and increased bounce strength. Aerotec Beam System: Implementing accurate data compiled from the field, Li-Ning manufactures the most aerodynamic racquets possible. Advanced calculations have resulted in racquets with extremely low drag and higher intensity. TB Nano: The nanometer technology combines carbon fiber and resin more closely. This method provides better elasticity, stability, and durability – resulting in more powerful striking. Stabilized Elastic Shaft: We filled the slim shafts of our Racquets with the same aramid fibers found in body armor and helmets. These heat-resistant and strong synthetic fibers provide world-class flexibility and durability. This is another way Li-Ning helps avoid sports injuries. Cubic Locking: These slim-grooved grommets lock in and protect the exposed portion of the string along the edges of the Racquet. They help provide shock absorption to make your shots even more accurate. Stabilized Torsion Angle: With a Stabilized Torsion Angle, shots that are not hit with the racquet’s sweet spot are designed to act almost as if they were. This torsion resistance performance allows the frame to stabilize for an even-hitting surface.
