XB2 Concept.

The XB2 is typically XRAY–premium, professional, high competition R/C car for the most demanding racers, developed with attention to the smallest details and backed by premium service & support…a luxury masterpiece.

USA Champion.

At some of the world’s most competitive off-road race – the USA National Championship, it was the XRAY’s Ty Tessmann who brought the first USA National Champion title for the XB2 platform using some of the prototypes of the new 2018 parts. Tested and successfully run in the highest competition races now you can enjoy the winning platform.

Made in Europe.

Designed, developed, and fully manufactured in-house at the XRAY factory in Slovakia, Europe, using the most high-tech German and Swiss machines and premium European materials, crafted with XRAY’s legendary attention to detail by our artistic production specialists. The XB2 is truly a masterpiece.

Development.

After my successful participation in development of the XB4 platform that culminated into a World Championship win, the XB2 was my first truly complete project that I have worked on from the ground up.

Perfection.

Designed in virtual reality using the world’s most sophisticated CAD tools, and manufactured using the world’s best machining and molding machinery, the XB2 achieves a level of premium perfection in all details that is second to none.

Racing Team.

Successful development of the XB2 – like all other XRAY platforms – would not have been possible without the involvement of the entire racing team working the entire year to test new ideas, prototypes, and improvements. The racing team travels to all major races around the world to provide XRAY drivers with first-class support & service so they can be assured that they always get 1st class treatment as part of the XRAY team.

Chassis.

All-new chassis made from custom-produced 2.5mm Swiss 7075 T6 aluminum. The special design ensures that different areas of the chassis have the proper flex – either stiff or soft – to decrease the CG. The precision milling allows the chassis to be stiff enough to perform properly without risk of bending.

CNC-machined from high-quality 2.5mm Swiss 7075 T6 aluminum, the chassis is lightweight without affecting strength or rigidity, and is additionally black coated at XRAY’s own in-house fully robotic coating line.

Weight distribution, chassis width & length, and proper flex have all been incorporated into the design of the chassis.

Upper Brace.

To improve front chassis flex, the front composite chassis braces were redesigned and shortened to allow for mounting all-new graphite side guard braces for better stability and performance.

Suspension Holders.

All-new narrower suspension holders with new rear suspension geometry gives increased rear traction.

The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.™) which allows for quick & easy suspension geometry set-up.

Gear Box.

The gear box has an updated, narrower design to accommodate the new narrower suspension holders. Using the new narrower suspension geometry, the XB2 generates more rear traction.

The lightweight, tiny gear box accommodates 3-gear configuration with right-side motor position.

Gear Differential.

Gear differential features all-new diff-outdrives designed for use with new 2.5mm pin.

The new stronger diff outdrives are the result of a new hardening process that increases lifetime and reliability.

The XB2 rear gear differential is standard in the Carpet Edition, offering increased on-power steering that is beneficial on nearly all types of tracks but is especially great on carpet and astro turf.

The super-smooth gear diff includes a composite case and cover with internal satellite gears that are precision-molded from special XRAY-developed graphite composite material, ensuring long lifespan and super-smooth efficient operation.

Drive Shafts.

To improve the drivetrain efficiency, the all-new CVD drive shafts feature new 2.5mm drive pins.

XB2 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 lifespan and reliability.

Wheel Hubs.

New 4.5mm off-set wheel hubs are included in the XB2 to compensate for the new narrower suspension holders, allowing the car to keep the same track-width.

The ultra-lightweight 12mm wheel hex drive hubs are CNC-machined from Swiss 7075 T6 black-coated aluminum. These ultra-true hex hubs have a clamping design which ensures ultra- solid mounting of the wheel on the hub.

The rear alu hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting.

To adjust track-width, additional offset wheel hex drive hubs are optionally available.

Shocks.

To improve the precision of the shock shaft movement, the front composite shim was redesigned and updated with a more accurate mould design.

Well-built, reliable shock absorbers are extremely important for super-smooth suspension action on any type of track. The shocks on the XB2 have been specifically designed to be built easily, perform consistently, and last reliably. Careful attention was paid to the smallest details during the design process, as well as during long-term testing in various conditions.

The shocks are membrane-free, yet they still allow for easy, consistent building and rebound setting using the bleed-screw shock cap design.

Downstop is adjusted using composite shims under the pistons. Upstop travel is adjusted using composite shims under the shock collar.

The aluminum body, lower nut, and bleeder shock caps are all machined from premium Swiss 7075 T6 aluminum.

Shock rods are machined from special steel material, precision hand-ground for maximum smooth operation, and additionally hardened for improved lifespan.

Philosophy.

At the heart of XRAY’s philosophy is a firm commitment to perfection when it comes to engineering, design, performance and support, all made possible by state-of-the-art in-house manufacturing. The XB2 is the epitome of perfection that is typical for XRAY.

XRAY XB2 Designer

Making Of.

The 3 years of development of the XB2 were full of blood, sweat, and tears, and certainly the most challenging yet rewarding years of my life. During those few years, my understanding of RC cars grew and expanded to a whole new level with all-new R&D knowledge and experiences that I am sure will help XRAY further develop our off-road platforms.

Read my exclusive story about Making of the XB2 to get a small glimpse of the challenges I went through to make this project a reality.
Martin Bayer
XRAY XB2 Designer – European Champion

Uni-Platform™.

The XB2 platform works at the highest competition level in any track conditions, whether it be super-low-traction dusty tracks, medium-traction, or super-high-traction carpet or astro turf; there is an XB2 for you that will handle flawlessly in any of these conditions.

There are two different XB2 kits to choose from – Carpet Edition and Dirt Edition, both built on the same platform with full compatibility and with interchangeable parts.

The Carpet Edition is designed for medium to very-high traction conditions, while the Dirt Edition is designed for very-low to medium grip conditions.

The Uni-Platform™ allows either XB2 edition to be tuned or converted to suit any track conditions with only a few additional parts.

Multi-Flex™.

The invention of 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 to help XRAY cars dominate races at local and national levels.

The XB2 incorporates Multi-Flex™ adjustment technology, which allows tuning the chassis flex for different track conditions.

Regardless if the track has low, medium, or super-high traction, you can adjust the chassis flex to suit track conditions to gain a distinctive advantage.

Chassis Weight Balance.

The layout of the XB2 was designed with attention to optimal weight distribution & balance. During the design and prototyping phases, 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 XB2 weight balance was specifically optimized for Carpet Edition and Dirt Edition, individually.

Carpet Edition – Gear Box and Motor Plate specifically designed to mount the motor in Middle position with top shaft positioned lower.

Dirt Edition – Gear Box and Motor Plate specifically designed to mount the motor in Middle position with top shaft positioned higher.

Electronics Layout.

The electronic layout allows for moving the batteries frontwards/rearwards, as well as using standard or mid-size servos and either using short pack or saddle pack batteries.

Multiple Servo Position.

To allow for more precise weight balance adjustment, the servo position is adjustable either more rearwards or frontwards; there are 3 positions to choose from.

When the servo is moved rearwards, there is more weight on the rear and less weight on the front. This results in less diving into a corner, while increasing rear traction. Recommended for low- and medium-traction conditions.

When the servo is moved more frontwards, there is more weight on the front and less weight at the rear. This increases the diving effect but reduces rear traction. Recommended for high- and very-high traction conditions.

Side Guards.

Side guards are an integral part of the XB2 Multi-Flex™ system. Moulded from medium-hardness composite material, the side guards make the chassis frame flex suitable for the majority of track conditions.
The tough composite side guards feature double-sided Velcro™ tape to seal the body perfectly to the chassis and seal against dirt.

There are two different chassis braces available – medium (included) and hard (optional) – which are suitable for particular track conditions.

The included side guards are moulded from medium-hardness composite and make the car faster in corners.

An optional hard-hardness composite moulded braces give the car increased stability on jumps.

Chassis Brace.

The front lower chassis brace is another component of the Multi-Flex™ system that influences flex and handling. There are two different chassis braces available – medium (optional) and hard (included), each suitable for particular track conditions. The brace is mounted directly to the chassis to hold the entire front assembly and front suspension, including the front protection bumper.

An optional medium-hardness composite molded brace is suitable for low- and medium-traction tracks.

The included brace is moulded from hard-hardness composite and is suitable for high- and very-high-traction tracks.

Upper Deck.

As a part of the Multi-Flex™ system, the front upper deck is used to adjust chassis flex. There are two different upper decks available – medium (optional) and hard (included), each suitable for particular track conditions.

An optional medium-hardness composite moulded upper deck is suitable for low- and medium-traction tracks.

The included upper deck is moulded from hard-hardness composite, and is suitable for high- and very-high-traction tracks.

Gear Box.

The XB2 gear box is designed with all the finest details and craftsmanship incorporated. All parts fit perfectly together, and the super-easy access to the rear differential will be appreciated by every racer. The durable gear box houses the differential with all the rear transmission, and allows the mounting of the rear roll center holder, motor plate, and rear shock tower.

Carpet Edition and Dirt Edition each have unique gear boxes specifically designed for different track conditions.

Gear Box Gears.

To generate maximum traction, steering and high-speed stability the gear box uses 3 gears configuration. For some specific track conditions such as large and open tracks an optional 4 gears configuration can be used.

Easy Diff Access.

Access to the rear differential is super easy on both Carpet Edition and Dirt Edition. By just releasing a few screws on the rear cover of the gear box, the differential can be easily taken out and inserted back inside without the need for further disassembly. Smart engineering.

Drivetrain.

The XB2 is a conventional gear-driven 2WD off-road car featuring:

Rear ball differential (Dirt Edition) or gear differential (Carpet Edition) with adjustable oil viscosity, featuring 53T gear and internal satellite gears
36T graphite composite idler gear
20T super-lightweight Swiss 7075 T6 hardcoated aluminum top shaft
adjustable slipper clutch with 84T main spur gear
rear CVD drive shafts
Ball Differential

Dirt Edition only

The XB2 ball differential is standard in the Dirt Edition and is recommended for all XB2 configurations when used on very-low to medium-traction dirt and clay surfaces. The externally-adjustable ball differential is machined from HUDY Spring Steel™ and is additionally hardened for extra durability and long lifespan.

A high-quality carbide thrustbearing and carbide balls are included for ultra-smooth operation. The ball differential comes factory pre-assembled.

Slipper Clutch.

Power from the motor is transferred to the drivetrain via an externally-adjustable central slipper clutch for quick & easy tuning. The 3-pad slipper clutch ensures super-smooth clutch operation and efficient and consistent braking. It is very easy to make ultra-fine adjustments to the clutch externally.

The slipper clutch pads are made from ultra-efficient SLS material with very high slip efficiency, thus allowing very precise slip adjustment.

The lightweight slipper plates are machined from premium Swiss 7075 T6 and additionally hardened before a final black surface treatment. The plates have a machined relief which decreases the friction surface to assist with clutch slip adjustment. With this plate design, pressure is focused on the circumference of the clutch pads for increased efficiency.

Spur Gear.

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 XB2 is equipped with an 81T spur gear which suits the majority of tracks. For additional tuning, optional 75T, 78T, 84T and 87T spur gears are available.

Motor Plate.

The black-coated Swiss 7075 T6 aluminum motor plate holds the slipper clutch assembly as well as the gear box, and features an adjustable motor plate position. To reinforce the assembly, the motor plate is connected to the upper brace mount via a motor plate brace.

Carpet Edition and Dirt Edition both have different Motor Plates, specifically designed for the particular track conditions.

Battery Strap.

Changing batteries is quick & easy with the included battery strap with aluminum nuts. The battery pack can be installed either frontwards or rearwards, and the included foam spacer helps to ensure the battery pack will not fall out. The chassis layout allows the use of either short packs or saddle-pack batteries.

There are two different battery straps available – composite (included) and adjustable graphite (optional), each suitable for particular track conditions.

The included composite battery is suitable for low-, medium- and high-traction tracks.

An optional adjustable graphite battery strap is suitable for very-high traction tracks and suggested especially for carpet racing.

Suspension.

Correct suspension geometry is one of the most important features of any RC model car, while at the same time being one of the most difficult & challenging features for a designer.
Suspension is always a mixture of:

design and shape of individual suspension parts
flex and hardness
materials used
mounting system
geometry and position of mounting points of connecting parts

From the suspension arms, through the suspension blocks, to the light yet robust steering blocks, every suspension part has been carefully designed for the 2WD 1/10 off-road racing platform to provide responsive racing characteristics in all conditions.

I.S.S.™ Suspension Holders.

Using eccentric suspension bushings – which are inserted into Swiss 7075 T6 aluminum suspension blocks – as well as additional shims and turnbuckles, the XB2 suspension geometry can be completely adjusted for:

  • camber
  • toe-in
  • rear roll-center
  • anti-squat
  • track-width

Suspension Arms.

XB2 suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry, and materials used… these are all part of the concepts and details that are thoroughly reviewed to create optimum suspension arms.

The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough for extreme durability. The exclusive composite mixtures used for suspension arms are a perfect balance between reliability and performance.

There are three different suspension arms available: medium (optional), hard (included), and graphite (optional), each suitable for particular track conditions.

Caster Blocks.

The caster blocks are very lightweight, yet their construction makes them very stiff & rigid. Caster can be adjusted with values 0°, 2.5°, or 5° using included caster bushings.

There are two different caster blocks available: medium (optional) and hard (included), each suitable for particular track conditions.

Steering Blocks.

The tiny-yet-tough steering blocks are comprised of composite steering blocks and graphite Ackermann extensions for variable Ackermann positions.

The composite blocks are moulded from a special composite mixture for maximum strength.

There are two different steering blocks available – medium (included) and hard (optional), each suitable for particular track conditions.

Uprights.

The super-compact rear uprights feature 6 different upper roll center positions. The rear uprights feature 0° toe to ensure stability and to prevent suspension geometry changes in hard crashes.
There are three different uprights available: medium (optional), hard (included), and aluminum (optional), each suitable for particular track conditions.

Wheelbase & Weight Balance Adjustment.

Outer suspension pins holding the front caster block and rear uprights feature wheelbase shims for quick & easy wheelbase and weight balance adjustment. Using included shims in rear and in front, both front and rear blocks can be moved forward or rearward to adjust weight balance depending on track condition.

By moving the arms to the front, the balance & weight of the car are transferred more to the rear; this is recommended for medium- and high-traction conditions. By moving the arms to the rear, the balance & weight of the car are transferred more to the front.

Steering System.

The dual-arm steering system is very simple yet effective. The steering system is fully bearing-equipped with 8 high-speed ball-bearings for very precise steering. The Ackermann is easily adjusted by quickly & easily changing the 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.

Ackermann is also easily adjusted by inserting a shim on the steering plate as well changing various graphite extension plates on the steering blocks.

Turnbuckles.

For 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 and steering system.

Arm Mount.

The lower composite arm mount is an important part of the chassis where the lower arms mount, and the block has an integrated 26° kick-up angle. Optional aluminum and brass arm mounts are available for further weight balance adjustment.

Shock Towers.

Front and rear shock towers include multiple shock positions, and the rear shock tower also holds the wing mount.

Carpet Edition includes shock towers machined from premium-grade graphite.

Dirt Edition features composite shock towers in order to generate more traction.

Shock Springs.

The XB2 springs have been specifically designed to complement the shocks.

The XB2 springs, like all other XRAY springs, are manually measured, selected, and matched into pairs to guarantee precisely equal length and damping characteristics.

There are two types of springs offered:

  • Linear – the spring rate is constant during the entire spring compression. Springs with different spring rates are available as optional tuning parts.
  • Progressive – The main advantage & benefit of progressive springs is that as the car initially enters the corner the springs work like a softer spring to provide maximum traction. As the chassis begins to roll in the middle of the corner, the spring rate progressively increases until it works like a stiffer spring which allows the car to maintain maximum cornering speed.

Each of the springs is laser-engraved with stripes to clearly indicate the firmness of the spring.

Shock Pistons.

Shock pistons are made from Delrin® and are molded using ultra-high precision moulds. All-new 2-hole pistons (1.6mm and 1.7mm holes) are now included in the set.

Variable Shock Mounting.

The 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 at the Carpet Edition either in front or behind the shock tower to adjust the weight balance.

Body.

The high-performance, low-profile aerodynamic body was designed by XRAY to perfectly fit the XB2 and to work effectively in most track conditions. The front and rear of the body (together with the central rib) have been designed for additional downforce to stabilize the car.

The body sides as well as cockpit sides are as flat as possible to direct airflow around the body for improved side stability. On the top of roof, two flow channels are incorporated for proper airflow.

The body is made from high-quality premium Lexan™ material.

For very-high-traction track conditions, an optional ultra-lightweight body is available to reduce the roll of the car and improve rotation in corners.

Wing.

The stylish and effective rear wing was designed to work perfectly with the XRAY XB2 body. Made from strong Lexan™ material, the wing is supported on the mounts by extra flat shims to better support and extend the life of the wing.

An optional thicker 1.5mm (#323511) rear wing is highly reliable with less chance of breakage, while at the same time influencing the performance of the car as well. The thicker wing gives higher traction and stability, but gives reduced steering.

The Carpet Edition includes front Lexan™ wing that is used to generate front downforce and is mounted directly on the front shock tower.

Wheels.

The included XB2 wheels are perfect for high-competition racing. The wheels are made from a very flexible material, while still being ultra-durable to withstand impacts. The side of the wheel is aerodynamic for maximum performance. The wheels were designed to provide maximum traction.

Internal reinforcement ribs make the wheels as stable as possible and eliminate deformation. The wheels feature a 12mm internal hex.

Anti-roll Bars.

In specific track conditions when the rear of the car must be stabilized, an optional rear anti-roll bar (#362400) can be easily installed. The anti-roll bar is mounted to the rear roll center holder and can be adjusted via the included linkages.

Anti-roll bar wires of different thicknesses are optionally available for fine-tuning; the wire thickness is laser-engraved for easy identification.

Ball-bearings.

A full set of 22 high-speed, blue-sealed ball-bearings are used throughout the drivetrain to ensure maximum efficiency. All bearings are degreased and oiled with AeroShell® Fluid 12 for maximum smoothness and long life.

Adjustment Possibilities.

The extensive range of adjustment possibilities includes: caster, camber, toe, kick-up, anti-squat, ride height, downstops, track-width, lower roll center, upper roll center, roll center position, bump steer, wheelbase, Ackermann, adjustable shocks, adjustable rear diff, adjustable slipper clutch, and adjustable XRAY Multi-Flex™.

Chassis Balance.

Chassis design focuses on balanced weight distribution and weight transfer. The chassis features pre-drilled holes for additional weights for optimum car balancing. Centerline holes are pre-drilled for easy balancing with the HUDY Chassis Balancing Tool #107880.

Silicone Oils.

HUDY Exclusive Silicone Oils are manufactured in Europe and each batch is laboratory tested and calibrated to ensure the highest possible consistency and quality from batch to batch. Based on the industry-standard cSt rating, the new line of oils will be easy to identify, adjust, and feel.

When following any set-up sheets by XRAY or XRAY team drivers, you can be sure that the oils you will get for your car are exactly same as those used by the factory racing team, thus ensuring very exacting set-ups and handling.

HUDY Chem Series.

Graphite Grease.

The XB2 includes premium HUDY Graphite Grease which is a high-performance, advanced-technology semi-fluid lubricant which incorporates both extreme pressure additives and finely-dispersed graphite for load carrying. It is intended primarily for the lubrication of rotating parts and loaded gears. In addition to providing outstanding load carrying, it is formulated to have excellent adhesion and resistance to “fling-off” under extreme conditions. The grease reduces wear and increases parts life.

HUDY Graphite Grease #106210 .
