Victor Thruster F C Ultra X 4U is an advanced and somewhat lighter, more manageable version of the Thruster F C Ultra X model. It is intended for players who want to maintain the power and stability of the Thruster series, while needing more speed in defense, drive shots, and rapid exchanges.
The model belongs to Victor's Thruster series, which is developed for aggressive play, powerful smashes, and efficient energy transfer. Because of the head-weight balance of the racket, at impact it creates more pressure on the shuttle, making it suitable for players who like to take the initiative and finish points with strong attacking shots.
The 4U version is lighter and faster than the 3U version, thus offering a better balance between power and maneuverability. It is especially excellent for aggressive doubles play, where a player needs enough power for an attack, but also quick reaction in defense, interception, and net play.
The racket features a 5.8 mm shaft that ensures precise and stable energy transfer. In the shaft, the Metallic Carbon Fiber technology is used, where a thin metal layer and high-strength carbon fiber are combined into a material with excellent elastic feel. This increases responsiveness, improves power transfer, and enables faster drive shots.
In this version, the Power Ring technology is integrated, further strengthening the lower part of the racket and improving shaft stability. The result is a stronger, more controlled, and whip-like swing that helps explosive shuttle acceleration.
The frame and shaft are additionally reinforced, so the racket allows string tensions up to 14.0 kg or 31 lbs. Technologies such as Nano Fortify TR, 46T PYROFIL, Nano Aerogel, HARD CORED TECHNOLOGY and Free Core ensure stability, vibration damping, greater rigidity, and a better feel in fast play.
The Victor Thruster F C Ultra X 4U/G5 is an excellent choice for advanced recreational players and competitors who play aggressively, want to dominate exchanges, and need a racket that combines power, speed, and control.
Who is it suitable for?
We recommend the Victor Thruster F C Ultra X 4U for players who:
If you want maximum stability and power for singles play, the 3U version is more suitable. If you want an even lighter and faster racket, check out the 5U version.

PYROFIL carbon fibers and their composites are advanced high-performance materials from Japan. Because of incredibly tight bonds and ultra-light structure, they guarantee amazing dampening of vibrations and significantly improve racket control.
Is inspired by helicopter rotor technology. A multi-layer structure and a composition of carbon fibers decreases material size and increases feeling and play characteristics.

Designed with the help of a computer simulation and injection molding technique. Revolutionary handle style enables a smother shaft movement, which allows for a smother swing and improves control and maneuverability.

Power Ring connects the shaft with the Free Core technology and improves the stability of the bottom part of the racket. At impact the shaft bends more controllably and returns to its original state faster, so the energy transfers to the ball more effectively.
For the player that means a firmer feeling in hand, better energy transfer and more elasticity when swinging. The racket is more stable at fast swings, while also helping create a more explosive, whip like acceleration for smash and drive strikes.
Combination of thin metal plates and highly resistant carbon fibers, Is combined into fibers: Metallic Carbon Fiber, which offers a unique and elastic feeling and incomparably impactful experience. Including Metallic Carbon fibers into the frame increases power of the smash strikes and improves the firmness of the construction, while its use in the shaft brings a pronounced elastic feeling at ball impact and a more effective force transfer. Resulting in faster strikes, s more precise orientation and more stability during games.
Nano Fortify TR uses TORAYCA® PREPREG material of a Japanese manufacturer Toray. Improves elasticity, strike resistance and the rackets responsiveness, which enables smother and more effective strike execution.
VICTOR Anti-Torsion System: The rackets shaft is crucial for power transfer, that is why VICTOR has long been dedicated to the development of better shafts. With a combination of highly responsive materials and an innovative design VICTOR has created their best shafts yet, with incredible resistance to torzical twisting and great flexibility.
Different frame structures, including with the POWER-BOX, DIAMOND, AERO and AERODYNAMIC technologies, have been rearranged and linked into a unified whole based on computer simulations. The purpose of this kind of structure is optimizing the playing surface, frame characteristics and the rackets’ whole efficiency.
NANO AEROGEL, the lightest hard material in the world, is built into the rackets frame. By redistributing the weight balance in the frame and higher use of carbon fibers effectively improve the firmness of the frame and strike feeling.
