Team Xray XB4 2wd Buggy

Xray XB4 2wdWe’ve been hearing rumors that this would be coming down the pipeline and now it is finally a reality, meet the Team Xray XB4 2wd buggy! Based on the high performance XB4 platform, the 2wd version shares all the racing DNA of the XB4 4wd and almost all parts to make both cars fully compatible with each other. While most parts are interchangleable between the the 2wd and 4wd versions of this car Xray has developed a few new 2wd specific pieces including +2mm aluminum rear suspension holders, aluminum front upper plate, front wheel axles, new DMX body, aluminum steering plate, new top deck, and new springs.


Multi-Flex

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 2WD is the world’s first 1/10 off-road 2WD chassis incorporating the Multi-Flex adjustment technology, which allows tuning the chassis flex for different track conditions. 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.

Chassis
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. 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.

Chassis weight balance
The layout of the electronics placement 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.

Motor Mount
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.

Diff Bulkheads
XRAY’s genuine attention to the smallest details, R&D and engineering are obvious in the design of the diff bulkheads. Unique bulkheads allow super fast and ultra comfortable diff exchange and servicing by dismounting only 4 screws from the front of the bulkhead and from the bottom of the chassis. This super fast diff access is available both in the front and rear.

Gear Differential
The XB4 2WD 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.

Ball Differential
The optional ball differential was designed for and is recommended for low-traction track conditions. The externally-adjustable ball differential is machined from HUDY Spring Steel and additionally hardened for extra durability and long lifespan. A high-quality carbide thrustbearing is included for smooth operation and the carbide balls ensure ultra-smooth running. The ball differential comes factory pre-assembled.

Diff Outdrives
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.

Slipper Clutch
The power from the motor is transferred to the drive train via an adjustable central adjustable slipper clutch for quick and easy tuning. The clutch outdrives are super lightweight and manufactured from HUDY Spring Steel and are additionally hardened for extra life and reliability. The slipper plates are machined from premium Swiss 7075 T6 and additionally hardened and with a black final surface treatment. The lightweight slipper clutch plates have machined relief which decreases the friction surface to assist with clutch slip adjustment. With the new plates, the pressure of the plate is on the circumference of the clutch pads, which increases efficiency.

Suspension
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 2WD 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.

SFA Graphite Stiffeners
All-new innovative and unique SFA graphite stiffeners allow for super-quick suspension flex adjustment to easily adjust the traction of the car under 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.

Steering Blocks
The tiny yet tough steering blocks are molded from a special composite mixture for maximum strength. Composite steering block inserts allow for very fast and comfortable lower roll center adjustment. With additional shims and extra inserts a fine tuning of roll center can be easily achieved. For maximum drive train reliability larger 5×12 ball-bearings are used in the outer position with increased dynamic load. On the inner position the smaller 5×10 ball-bearings are used to minimize unsprung weight.

Rear Uprights
The very compact rear uprights are small in size but thanks to the special composite mixture used also very strong. The lower roll center adjustment has 2 different positions on the upright and the upper roll center adjustment has 3 different positions. The rear uprights feature 0° toe to ensure stability and prevent suspension geometry changes in hard crashes. For maximum drive train reliability larger 5×12 ball-bearings are used in the outer position with increased dynamic load. On the inner position the smaller 5×10 ball-bearings are used to minimize unsprung weight. The outer suspension pin on which the rear upright sits features shims which allow for additional wheelbase adjustment.

Clamping Alu Hex Hubs
Ultra-lightweight 14mm wheel hex drive hubs are CNC-machined from Swiss 7075 T6 black-coated aluminum. These ultra-true hex hubs have clamping design which ensures ultra solid mounting of the wheel on the hub. The aluminum hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting.

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.

Top Deck
The XB4 2wd top deck is a combination of graphite top deck and aluminum front brace connected via a bushing. The top deck is stiff in the longitudinal direction, but flexible in the cross direction. The front aluminum brace reinforces the front bulkhead and the steering system. The front body post is mounted on the aluminum brace.

Shock Towers
Machined from premium-grade 3.0mm graphite, the shock towers are lightweight and strong. Front and rear shock towers include multiple shock positions as well multiple roll center adjustment positions. The rear shock tower also holds the wing mount.

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 2WD 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.

    So they removed the driveshaft and call it a 2wd?

  2. Rick

    It is a beautiful buggy but yeah that is a little weird.

    I’d like to see how this compares on track against a high end 2wd buggy like the tlr22. I suspect that it probably handles pretty well on hard packed tracks but would get dogged on anything loose.

    Is this a joke? How lazy can you be?
