This badminton racket has very fast swing power, suitable for fast attack players. In addition, this racket also features a patented new Li Ning technology: the growth rate of diversion tunnel system, 5.7 point in the film frame reserved for the air duct, so that the air can be passed in from the film frame. Its main purpose is to reduce drag, increase swing speed.
LI NING FLAME F390 FEATURES:
Improved racquet mechanical structure for more efficient attack and defense. Increased "sweet spot" for improved hitting velocity with wider string area to increase bounce strength.
Aerodynamic design with low air resistance and high tensile strength. In the film frame position of the five points and seven pre-aside guide duct so the air can be passed from between the film frame. To reduce drag, increase swing speed.
"M"PCF(Multi-Layered Polymer Carbon Fibers): Reinforcing Technology
Handcrafted multi-layered carbon producing multi-directional strength.
Provides strength & durability at key stress points.
"H"DF (High Density Foam): Shock Absorption
High tech and light weight shock absorption materials fill racket head cavities
Lightweight, high-tech shock absorption materials within racquet frames that minimizes arm strain at impact.
"U"HB (Ultrafine High Tensile Biometric): High Flex Point
Racket shaft flexes closer to the racket head to produce improved smash and drop shot performance.
With an optimized shaft performance, this technology provides low wind resistance with high-flexibility & strength for superior smashing!
TB.NANO (TB Nano Powertec) : Nanometer Technology
Enhanced nano technology bonds carbon fibres to resin to increase the raw material strength by 20%
Original Li-Ning TB Nano Material Science and Technology creates a more stable and finer racket. More Powerful "sweet spot".
Aviation Technology with Introducing aviation Technology design that releases the metal performance memory and improves control an strokes. The inter-field application of aviation technology on Li-Ning products. The frame from 3 & 9 o'clock zones made of ultra elastic 3G titanium alloy, which resists shake and vibration. The distinguished feature of metal memory will control the frame restoration precisely at the moment of deformation and to restrain the shake resulting from vibration waves. The anti-tarsion performance of strokes is improved under high tension conditions and brings about a quick exact and stable second stroke.
