Team Xray raised the bar in the 1/10 buggy class with the XB4, bringing a new high-quality, high-performance player into the field for all others to measure themselves against. Now with a more adaptive platform, the Team Xray XB4 2015 Edition is even more of a beast to beat. More information and pictures about the new XB4 after the jump!
Team Xray presents the new 2-in-1 concept in the XB4 2015, giving the ability to change or reposition components on the car to use a short lipo battery pack -or- saddle packs. Everything has been considered, adapted, and included: repositionable bulkheads, slipper clutch, and motor mount; different upper decks and center CVD drive shafts; even a repositionable radio trays and servo mounts. This is an incredible leap forward to make the XB4 platform ultra-diverse to satisfy the needs, wants, and desires of racers around the world.
The new XB4 2015 is artistically crafted in our in-house Xray factory by design & production specialists, and then extensively tested and refined by the world’s best drivers. Designed, developed, and fully manufactured in Slovakia, Europe, with Xray ‘s legendary attention to the details, fine materials and extreme performance, I am excited to present you the all-new XB4.
You now have the choice to use either a short battery pack -or- saddle packs; the new XB4 is designed to fit both perfectly! With the all-new 2-in-1 concept, you can easily transform the saddle pack configuration into a short pack battery configuration and place the motor either frontwards or rearwards… all parts for the transformation are included.
Chassis Weight Balance
On the XB4 2015 you can easily adjust the weight balance with the all-new 2-in-1 concept. You can move the motor frontwards and rearwards, but you can do this independently of the short battery pack. You can also place the electronics – including servo – on either left or right as well.
CNC machined from high-quality Swiss 2mm 7075 T6 aluminum, the XB4 chassis is strategically machined in low-stress areas to make it as light as possible without affecting strength or rigidity. Weight distribution, chassis width, and chassis length have a key influence on the handling of the car. All of these features were incorporated into the design of the chassis. All screw holes on the bottom of the chassis are countersunk, allowing for a very smooth chassis underside with no protruding screw heads. To increase the lifetime, the chassis is hardcoated at Xray’s own in-house fully robotic operated coating line.
The front and rear lower composite braces are mounted to the aluminum chassis, and reinforce the XB4 chassis assembly with the desired flex. The wires between the motor and electronics are routed via a channel in the front brace to ensure they do not interfere with the drive shafts or other rotating parts.
The Xray XB4 2015 is equipped with both front and rear top decks which not only hold the body mounts but also reinforce the chassis assembly by connecting the front and rear bulkheads with the central drive system. The length, thickness, width, and shape of the top decks are all features that have a significant influence on handling. With the all-new 2-in-1 concept, the XB4 includes two sets of front & rear top decks, each specifically designed for use with either the short battery or saddle pack battery configuration. Depending on the configuration of the car, the appropriate top decks are installed to ensure the highest performance and best handling. All top decks are machined from high-grade graphite. The Xray XB4 2015 top decks capture the central drivetrain bearings and hold them in place in their supporting bulkheads.
Central Drive Shafts
For the new 2-in-1 concept, the XB4 2015 includes two pairs of central drive shafts of different lengths, each specifically designed for use either with short battery or saddle pack battery configurations. The XB4 constant velocity drives (CVDs) are manufactured from world-renowned HUDY Spring Steel. The drive shafts are some of the world‘s thinnest yet most durable drive shafts used in electric off-road cars. Hardened with a proprietary hardening process, the drive shafts provide unbeatable lifetime and reliability.
The CVD safety collars were reinforced to increase reliability and keep the mounting pin solidly in place. The safety collars are molded from a special composite mixture for maximum strength.
Both front & rear diff crown gears and pinion gears on the XB4 2015 are made from steel which has been additionally hardened to ensure increased lifespan and reliability. The width of the crown gear teeth is narrower to allow the gear to be as light as possible. The width of the pinion gear teeth is wider to allow it to work also with optional composite and aluminum crown gears.
The XB4 2015 gear diff ensures increased on-power steering for nearly all types of tracks, and is ideal for both carpet and clay tracks. The super-smooth gear diff includes a composite case and cover with integrated crown gear. The internal gears are precision-molded from tough XRAY developed composite material, ensuring long lifespan and super-smooth, efficient operation. The maintenance-free diff design will benefit racers of all levels. When the diff is correctly built, there is no need for maintenance for a very long time… no need for frequent oil changes, and no leakage due to our superior sealing system.
The all-new motor mount is another smart and innovative solution from XRAY. The motor mount design allows the entire mount to be rotated from right to left to allow the motor to be mounted either frontwards or rearwards. The motor is connected to an eccentric mounting plate, with the assembly then inserted into an integrated motor holder/drivetrain support. The design allows quick & easy motor rotation to adjust gear mesh, and yet clamp securely using only a single screw.
The new central bulkhead was designed to support the 2-in-1 concept, to allow the slipper clutch to be oriented either frontwards or rearwards. The graphite central upper deck holds ball-bearings in the motor mount and bulkhead assembly, while the design of the upper deck allows for very easy access for slipper clutch adjustment.
The power from the motor is transferred to the drivetrain via an adjustable central slipper clutch for quick and easy tuning. To accommodate the new 2-in-1 concept, the slipper clutch shaft was redesigned with a centric design to allow it to be positioned either frontwards or rearwards. The lightweight slipper clutch plates have a machined relief which decreased the friction surface which assists with clutch slip adjustment. With this plate design, the plate pressure is on the circumference of the clutch pads, which increases the efficiency. The slipper clutch pads are made from ultra-efficient SLS material with very high slip efficiency, thus allowing very precise slip adjustment. The XB4 2015 clutch spring is much stronger to improve consistency and give ultra-fine slipper clutch adjustment. The clutch outdrives are super lightweight and manufactured from HUDY Spring Steel and then additionally hardened for extra life and reliability. The slipper plates are machined from premium Swiss 7075 T6 and additionally hardened then given a black final surface treatment.
Precision-molded spur gears are made from XRAY’s exclusive secret blend of composite material, allowing the gear to run true yet be robust enough to handle high-performance brushless motors. The spur gears are designed to have the lowest possible weight while staying strong and light. Each gear is stamped with the tooth number for easy identification. The XB4 is equipped with a 81T spur gear which suits the majority of tracks. For additional tuning, optional 75T, 78T, and 84T spur gears are available.
Front & rear bulkheads were reinforced to withstand rigorous impacts and abusive racing conditions. The diameter of the holes for ball-bearings was refined to minimize ball-bearing play which results in increased lifetime of the gear teeth and minimized gear stripping.
The new 3.5mm graphite front shock tower was thickened for increased lifespan, and the new design features the two most frequently used roll center positions. Both front & rear shock towers are machined from premium-grade graphite, are lightweight and strong, and have multiple shock positions as well as multiple roll center adjustment positions. The rear shock tower holds the wing mount.
I.S.S. Suspension Holders
The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.) which allows for super-fast & easy suspension geometry setting. This Xray concept was first introduced in the very first XB8 and now has been carried over to the 1/10 scale XB4 2015.
A very handy, compact radio plate allows for mounting the receiver and speed controller for quick & easy removal and assembly. The antenna mount allows the electronics to be located in one place for easy servicing.
With the all-new 2-in-1 concept, the XB4 includes two short and one long battery strap to accommodate either a short battery pack or saddle packs. The battery strap holders were updated with a new higher design, and the front holders are completely new.
New servo mounts allow the servo to be installed on either left or right side to allow for weight balance adjustment. The chassis and side guards have predrilled holes to allow the servo mounts to be mounted on either side.
The front lower bumper was redesigned for improved protection. The bumper now protrudes from the bottom of the chassis to absorb all impacts from contact between the chassis and the track surface.
The new, aggressive XB4 2015 body is wider to fit the new wider layout and the new 2-IN-1 concept. The high-performance low-profile aerodynamic body was designed by XRAY to perfectly fit the XB4 and to work in most track conditions. The front and rear of the body have been designed to provide downforce for maximum stability. The body sides as well as the cockpit sides are as flat as possible to direct airflow around the body for maximum stability. On the rooftop, two flow channels are incorporated for proper air flow. The body is made from high-quality premium Lexan material.
XRAY Multi-Flex Technology has resulted in some of the most significant milestones in RC model car development in the last decade. This innovation has proven to be a distinct competitive advantage at tracks worldwide, helping XRAY cars dominate races at local and national levels. The XB4 is the world’s first 1/10 off-road chassis incorporating Multi-Flex adjustment technology, which allows tuning the chassis flex for different track conditions. Whether the track is low, medium or super-high traction, you can adjust the chassis flex to suit the track conditions in a matter of seconds, and again adjust the flex easily when the conditions change. It has never been so easy to professionally set-up flex… yet another smart innovation from XRAY.
Suspension arms are one of the most important parts of any RC model car, as they directly influence the handling characteristics of the car. The XB4 2015 suspension arms are the result of long-term tests of different designs and layouts. Length, thickness, flexibility, geometry of suspension points, and materials used… these are all the concepts and details that had to be thoroughly reviewed to create optimum suspension arms. The exclusive composite mixture used for suspension arms is a perfect balance between reliability and performance. The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough to provide extreme durability.
HUDY Spring Steel Turnbuckles
To guarantee maximum reliability, all turnbuckles are manufactured from special HUDY Spring Steel material for turnbuckles which features a tougher core. These turnbuckles are used for front & rear upright linkages, steering system, and also for the servo saver.
Well-built, reliable shock absorbers are extremely important for super-smooth suspension action on every type of track. The shocks on the XB4 have been specifically designed to be built easily, perform consistently, and last reliably. Attention was paid to all the smallest details during the design process, as well as during the long-term testing in various conditions and track types. The aluminum body, lower nut, and bleeder shock caps are all machined from premium Swiss 7075 T6 and then black hardcoated for maximum strength and durability. The pistons are made from Delrin and are molded using super-precise moulds. There are several types of pistons included with different holes and diameters for precise shock adjustments. For custom adjustment, a set of blank non-drilled pistons are also included. The shock rods are machined from special steel material, precision hand-ground for maximum smooth operation and additionally hardened for increased lifespan.
