The 2014 Xray XB4 features a new composite chassis frame with a split design and separate front part and rear chassis plate. The split design allows the entire rear suspension to be mounted in either standard position using the rear chassis plate, or to be placed lower by mounting the rear suspension directly to the aluminum chassis. The direct mounting of the rear suspension increases traction and is recommended for low-traction tracks.
All-new arms feature the innovative SFA (Suspension Flex Adjustment). Whether you are racing in low- or high-traction track conditions, you can easily adjust the flex of the arms by quickly and easily adding optional graphite stiffeners which change the stiffness of the suspension. The new arms include 4 holes where the optional graphite stiffeners are mounted, and the areas around the holes are strengthened for maximum durability.
SFA Graphite Stiffeners
All-new XB4 innovative and unique SFA graphite stiffeners allow for super-quick suspension flex adjustment to easily adjust the traction of the car in various track conditions. Whether you drive in low- or high-traction conditions, with the smart graphite stiffeners you can very quickly and easily adjust your car to suit current conditions. At the beginning of a race event when traction is low, the arms are used without the SFA graphite stiffeners. As traction increases, the suspension can easily be made stiffer by mounting the SFA graphite stiffeners for more stability and easier driving characteristics. The graphite stiffeners give the car maximum stability in chicanes and allow for easier and smoother steering.
All-new XB4 ’14 suspension arms are narrower which allows for quick and easy wheelbase adjustment. Using included 2mm shims, both front and rear suspension arms can be moved either forward or rearward to adjust weight balance depending on track conditions. By moving the arms to the front, the balance and weight of the car are transferred more to the rear; this is recommendedfor medium– and high-traction conditions. By moving the arms to the rear, the balance and weight of the car are transferred more to the front; this is recommended for medium- and low-traction conditions.
Variable Shock Mounting
The new design of the rear suspension arm allows very practical variable position of the rear shock absorbers. Depending on track conditions, the rear shock absorbers can be installed either in front or behind the shock tower.
The power from the motor is transferred to the drivetrain via an adjustable central slipper clutch for quick and easy tuning. The new lightweight slipper clutch plates have a machined relief which decreased the friction surface which assists with clutch slip adjustment. With the new plates the pressure of the plate is on the circumference of the clutch pads, which increases the efficiency. The new slipper clutch pads are produced from new ultra-efficient SLS material with very high slip efficiency and allows very precise adjustment of the slipper clutch. The new clutch spring is much stronger which helps improve consistency and gives ultra-fine slipper clutch adjustment.
Front and rear bulkheads were reinforced for 2014 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’s teeth and minimizes the gears stripping.
New front and rear shock towers were redesigned and reinforced for the 2014 XB4 4wd Buggy. Machined from premium-grade 3.0mm graphite, the shock towers 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.
To new top deck was reinforced for increased reliability and other small details were improved for a more precise fit. The top deck is machined from high-grade graphite, and its main design purpose is not only to hold the body mount but also to reinforce the chassis assembly by connecting the front diff bulkhead with the central drive system. The top deck captures the central drivetrain bearings and holds them in place in their supporting bulkheads.
The optional ball differential was designed and is suggested for low traction track conditions. Externally adjustable ball differential is machined from HUDY Spring Steel and additionally hardened for extra durability and long lifetime. High-quality carbide thrustbearing is included for smooth operation and the carbide balls ensure ultra-smooth running. The ball differential comes factory pre-assembled.
The invention of the 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 not only resulted in awards and accolades, but has proven to be a distinct competitive advantage at tracks worldwide, helping XRAY cars dominate races at the local and national levels. The XB4 is the world’s first 1/10 off-road chassis incorporating the Multi-Flex adjustment technology, which allows tuning the chassis flex for different track conditions. It doesn’t matter if the track is low traction, 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 the flex. It is yet another smart innovation from XRAY.
The 2014 XRay XB4 buggy features a CNC-machined from high-quality Swiss 2mm 7075 T6 aluminum, the backbone is strategically machined in low-stress areas to make it as light as possible without affecting strength or rigidity. The strong aluminum backbone protects the bottom of the car from extreme conditions and abusive jumps. The aluminum backbone is perfectly fitted to the composite chassis frame and all holes are perfectly countersunk to provide a smooth surface.
Composite Chassis Frame
The precision engineered and designed composite chassis frame not only enables quick and easy Multi-Flex settings, but also houses the main components of the car. The front, center and rear drivetrain bulkheads are keyed into this frame, while it also provides locations for all of the required electronics. The chassis tray design features reinforcement braces in both lengthwise as well lateral directions. The tray design ensures perfect protection from bottom and sides without requiring additional components.
Chassis weight balance
The layout of the electronics placement on the 2014 XB4 was designed with the attention to the optimum weight distribution and weight balance. During the design and prototyping phase several different layouts were tested and an extensive amount of data was collected, compared and evaluated by the factory team before the final design was chosen. The motor mount is oriented in the front on the right side, with servo, ESC and receiver placed on the opposite side for balance. To maximize balance both L/R and F/R, a saddle pack battery configuration was used, with the batteries placed to the rear between the spur gear and the suspension mounts.
All the electronics can be comfortably placed within the composite chassis frame. The servo mount is held to the chassis using 2 screws for easy and fast exchange. There is plenty of space behind the servo for the ESC and receiver placement. Space has been reserved in front of the motor to allow for an additional cooling fan.
The motor mount is another smart and innovative solution from XRAY. The motor is connected to an eccentric mounting plate, with the assembly then inserted into an integrated motor holder/drivetrain support. The design of this system allows quick and easy motor rotation to adjust gear mesh, and yet clamp securely using only a single screw. To ensure that the motor will not come loose in a serious crash or if the motor mount is not tightened sufficiently, the motor plate has a bayonet mounting system which prevents it from being dislodged from the motor holder. By rotating the motor mount plate to the opposite direction, the motor can be quickly removed from the motor holder. Removing the motor or adjusting the gear mesh has never been more comfortable or faster with changes possible in just a few seconds.
The 2014 XB4 gear diff ensures increased on-power steering which is needed on 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 and mixed composite material ensuring high life time and super-smooth and efficient operation. The maintenance-free diff design is a feature that 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.
To reduce rotating weight, the super-lightweight diff outdrives are machined from HUDY Spring Steel™ material which allows us to additionally remove material on the outer part of the outdrives, further reducing the weight without effecting durability. The inner part of the outdrives are additionally hand-ground for maximum perfection and fitment into the diff case. The outdrives are hardened using XRAY’s own special hardening process to provide extended life time and reliability.
Precision-molded spur gears are made from XRAY’s exclusive secret blend of composite material, allowing the gear to run 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 comes equipped with 81T spur gear which suits majority of tracks. For additional tuning an optional 84T spur gear is available.
From the suspension arms, through the suspension blocks, to the light, yet robust steering blocks, every suspension part has been specially designed for 1/10 off-road racing platform to provide responsive racing characteristics in all racing conditions. Over the years XRAY has successfully gained and utilized extensive knowledge of suspension geometry and stiffness, which has been applied while designing the suspension parts. The ultra-lightweight suspension parts are molded from a special composite material that makes the parts very light yet very durable to withstand the rigors of high-performance racing. The XB4 platform features suspension parts inspired by the big brother XB9, yet re-engineered for the smaller 1/10 platform. The front and rear arms feature double shock mounting positions and integrated anti-roll bar mount.
Suspension arms are one of the most important parts of any RC model car, as they directly influence the handling and racing characteristics of the car. The XB4 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 the 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.
Dual Arm Steering System
The dual arm steering system is very simple yet effective and features an integrated easily adjustable servo saver. Ackermann is easily adjusted by quickly and easily changing steering link mounting positions on the steering plate. Bump steer is easily adjusted for more aggression by inserting a shim between the steering block and steering linkage.
HUDY Spring Steel Turnbuckles
To guarantee maximum reliability all turnbuckles are manufactured from special HUDY Spring Steel™ material for turnbuckles with a tougher core. These turnbuckles are used for front and rear upright linkages, steering system as well as for the servo saver.
Big Bore Shocks
Well built and reliable shock absorbers are extremely important for super smooth suspension on every type of track. The shocks on the XB4 have been specifically designed to build easily, perform consistently, and last reliably. Attention was paid to even the smallest details during the design process, as well as during the long term testing in various conditions and track types.
Anti-roll bars are manufactured from special spring steel material and are included to stabilize the car at both front and rear. The roll bars are easily mounted to the diff cases and can be adjusted through the adjustable linkages. Both front and rear anti-roll bars are interchangeable as they have same design and shape. The thickness of each anti-roll bar is laser engraved for easy identification. Anti-roll bar wires of different thickness are optionally available for fine-tuning.
