The AERONAUT 4000C badminton racket is built on the Aeronaut Technology Platform that has a unique air-stream channel integrated into the racket head. This reduces air resistance which helps to generate faster shuttlecock speeds. Li-Ning COMBAT rackets have a heavier head and a higher balance point. Suitable for very strong, aggressive players looking fthe best control with little to no sacrifice in power.
The AERONAUT Technology Platform uses a 4-digit numbering system. The first digit determines the grade of the racket as follows:
- If the first digit is 1, 2 or 3, the racket is suitable for beginners.
- If the first digit is 4, 5 or 6, the racket is suitable for intermediate players.
- If the first digit is 7, 8 or 9, the racket is suitable for advanced players.
BADMINTON RACKET TECHNOLOGIES:
Introducing aviation technology to control the racket frame. After impact, Li-Ning rackets absorb unnecessary shaking from vibrations and restore the racket’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 rackets. By implementing multi-layer carbon fibers, the racket is crafted with strength and longevity in mind.
DLi-Ning rackets 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 wider stringed area and increased bounce strength.
Implementing real data compiled from the field, Li-Ning manufactures the most aerodynamic rackets possible. Advanced calculations have resulted in rackets with extremely low drag and higher intensity.
The nanometer technology combines the 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 rackets with the same aramid fibers found in helmets. These heat-resistant and strong synthetic fibers provide world-class flexibility and durability. This is another way Li-Ning helps avoid sports injuries.
Our proprietary process thoroughly mixes resins with carbon fibers to ensure all our rackets are manufactured in a uniform manner. This provides optimum strength and consistent performance no matter which racket you choose.
These slim-grooved grommets lock in and protect the exposed portion of the string along the edges of the racket. 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 sweet spot of the racket are designed to act almost as if they were. This torsion resistance performance allows the frame to remain stabilized for an even hitting surface.
By changing the shaft’s recoil point, our rackets quickly bend and rebound back into position, so you are ready for the continuous volley and attack.
