YONEX is a leading manufacturer in sports equipment. YONEX produces quality badminton equipment for all types of players.
YONEX was founded by Minoru Yoneyam in 1946. He began by selling wooden floatation devices.
After plastic floatation devices were introduced, Yoneyam changed his focus.
After massive research on racquet materials, the science behind YONEX was born.
Material science is very important for making lightweight and durable badminton racquets.
YONEX uses the latest nanoscience technology to focus on developing the best racquets for advanced players.
With Nanoscience, YONEX is able to create ultra lightweight, high impact, thinner, and stronger (more durable) racquets.
YONEX Astrox 88s 3u vs 4u: A comparison
YONEX Astrox 88s
We will take a detailed look at the YONEX Astrox 88s series before we check out the YONEX Astrox 88s 3u vs 4u.
The Astrox 88s series is a slightly head heavy, mid repulsive racquet.
Yonex Astrox series racquets are fast and powerful. They are recommended for players who demand a steep angled and devastating smash.
Astrox focuses on the Counterbalance theory. Weight is distributed through the grip-end, frame top and the joint for maximum control.
As a result, the player is provided better balance and the player can quickly adjust the racquet for the next shot.
YONEX Astrox is focused on getting the steep angle of the attack. The technology of this racquet is able to offer players the flexibility needed to hit the steep angle attack.
The combination of attack and control is a feature unique to these racquets.
Let’s focus on the increased power and control achieved by the YONEX Astrox 88s:
- Smash Power up to 7.1%: The difference between the initial speed and the final speed is minimized in order to be launched strongly.
- Smash Angle is 2.3% steeper: Tested by YONEX- measurements made by a swing robot.
Yonex Astrox 88s specifications include:
- Frame: H.M. Graphite
- Material: Nanometric + Tungsten
- Shaft Material: H.M Graphite + Namd
- Flex: Stiff
- Length: 670mm +/- 2
- Maximum tension: 28 pounds
- Balance point: 295mm +/- 3 (head heavy)
- Flexible frame: The frame is made flexible for accurate shuttlecock control, while having more flex in the upper part of the frame. Maximum power is transmitted to the shuttlecock. The overall length is 10mm longer than previous models. This enhances both accuracy and power to provide powerful attacks.
- Shape: The shape allows the shaft to flex. More flex and faster graphite material stabilizes the racquet face by preventing shaft twisting-increasing control.
- Nanometric: The bonding strength between the carbon fibers is improved. Reduction in the amount of carbon in the shaft makes it 60% thinner than a conventional racquet while still retaining stiffness.
- Rotational generator system: Weight distribution: By applying the counterbalance technology mentioned above, weight is distributed throughout the grip end, frame top and the joint for maximum control.
- Namd: Astrox 88 uses the first new dimension graphite material Namd, which greatly improves the adhesion of the graphite fibers and resin attaching nanomaterial directly to the graphite fiber.
In high performance racquets it is common to combine nanomaterials with resin that connects graphite fibers, but in the Astro 88 nanomaterials are directly adhered to the graphite fibers and resin is greatly increased.
More Special Features from the Manufacturer:
- New Grommet Pattern: The single-pass grommet construction provides more grommet holes for a more high-performance stringing pattern.
- Isometric: The square-shaped isometric frame shape is designed to keep vertical strings at a similar length as well as the horizontal strings to produce an expanded sweet spot in all directions.
- New Built-In T-Joint: New Built-in T-joint is manufactured from a plastic lightweight combined with an epoxy resin and foaming agent that enhances quality and performance by increasing the stability of the shuttle on the string bed and through the air.
- Energy Boost Cap: The new shape allows the shaft to flex, which ensures the maximum effect of Namd (mentioned above) and stabilizes the racquet face by preventing the shaft twisting, increasing control.
- Solid Feel Core: The built-in solid feel core cuts harmful miscellaneous vibration at impact. Solid-feel core is carried in all racquets manufactured in Japan.
- Aero-Box Frame: Combines solid hitting and quick frame.
- Super Slim Long Shaft: The slimmest racquet ever produced by YONEX vastly reduces air resistance while providing maximum feel.
YONEX Astrox 88s 3u vs. 4u: Which is right for you?
What is the difference in performance between a 3u and a 4u weighted racquet?
YONEX defines 4u as dry weight between 80-84.9 grams.
3u is defined as dry weight between 85 -89.9 grams.
This is a difference of 5 grams.
The heavier racquet is a balance that optimizes specifics for the overhead strokes like clear and smash.
The added weight at the head facilitates the racquet to swing down faster/more forceful in this downward stroke.
The Chinese tend to call the head heavy racquet balance the forehand racquet, and the head light balance is called the backhand racquet.
For the ease of a downward stroke, the upward stroke is sacrificed.
The upward stroke is is the wrist/arm movement of the backhand swing.
To maneuver well, the upward stroke is important especially in a fast game.
Many players say the 4u is easier to maneuver and defend. However, 3u is more solid and offers slightly more power.
Pros and Cons
Pros of 4u:
- Less muscle fatigue
- Best for doubles because of speed and deference.
Cons of 4u:
- Sacrificing power
- Sacrificing frame stability
Pros of 3u:
- A singles player will find a 3u better since speed is not as important as stability. The stability and feel of the racquet head is most important.
- The 3U weight helps push the shuttle down. The lack of weight in the head makes the racquet great for back court deception shots
Singles vs. doubles
Because some of the pros and cons focus on playing singles VS doubles, we will check out the differences in the games.
The speed of the shuttle is different is singles than it is in doubles. The doubles game is a faster game than singles.
Singles places more emphasis on movement pressure (footwork) and doubles emphasis is on shot making pressure (quick handling of the racquet.
As we mentioned above, 4u works better for doubles play and 3u singles play.
