Chassis Xray XB4

The chassis is updated to accommodate all the new features including the new front and rear bulkheads, the new suspension holders and the tweak-free Quick Battery Holders.

The chassis is an important component that contributes to the XB4’s handling characteristics. The chassis dimensions and flex characteristics are selected for the best blend of stability, traction and steering. The chassis is machined for extra clearance under the bulkheads to accommodate the new diff height adjustment feature.            

CNC-machined from high-quality Swiss 2mm 7075 T6 aluminum, the chassis is strategically machined in low-stress areas to make it as light as possible without affecting strength or rigidity; and it is additionally black-coated for increased lifespan.

 

Bulkheads Xray XB4

All-new front & rear bulkheads feature a horizontal split design (HS) to retain easy diff access while adding the valuable new diff height adjustment. The unique design of the bulkheads uses an inline bushing to alter the alignment and height of the bevel drive gear. In addition to accommodating the new diff height adjustments, it also allows the front central driveshaft to operate with a reduced angle for less friction and wear on the CV joint components and improved driveline efficiency.

The XB4 bulkheads allow fast and easy differential access for setup changes or servicing by removing only 4 screws from the upper gear box cover while the lower section remains mounted to the chassis. This super-fast diff access is featured on both front and rear gearboxes.

The super-strong, narrow bulkheads provide the needed clearance for the redesigned suspension holders with increased set-up range possibilities.

Diff Height Adjustment Xray XB4.

All-new front & rear HS bulkheads allow for a new diff height adjustment using eccentric bushings. In the front gearbox, the diff height has 3 different settings. The rear differential can be adjusted through a 5mm range. The diff height adjustment is a vital set-up capability that allows quick set-up adaption for either Carpet or Dirt tracks.

Carpet edition uses a lower ride height and the upper differential position to keep the drive shafts level.

Dirt edition typically uses a taller ride height and a lower differential position to keep the drive shafts level.

 

Central Drive Train Xray XB4.

The new design of the HS bulkhead with the inline bushing for the bevel drive gear creates a more linear orientation for the front center drive shaft to reduce the CV joint angle for increased driveline efficiency and decreased friction and wear.  The height and angle of the rear center drive shaft is also adjustable depending on the height adjustment of the differential.

Front - there are 3 different angle configurations for adjustment of the front drive train.

Rear - there are 6 different height configurations for adjustment of the rear drive train.

Diff Gears Xray XB4.

The new pinion gear is shorter to allow the drive shafts to move the CV joint closer to the differential to improve drive train efficiency.

Both crown gear and pinion gear are CNC-machined from HUDY Spring Steel and are ultra-hardened making them very strong and reliable with a longer life span. The split crown gear allows for a simpler exchange to optional gears without requiring a rebuild of the internal diff assembly and results in significantly lower rotating mass and improves the serviceability.

To improve the gear engagement both crown gear and pinion gear have more teeth and geometry that results in smoother engagement and increased efficiency.

Center Driveshafts Xray XB4.

All-new longer front and rear central driveshafts integrate with the new gearbox dimensions and move the CV joint closer to the differential to improve drive train efficiency.

XB4 constant velocity drive shafts are manufactured from world-renowned HUDY Spring Steel™ and feature 2.5mm drive pins for maximum drivetrain efficiency. 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.

Slipper Clutch Xray XB4.

The unique Multi-Adjustable Slipper Clutch – MSC, with independently adjustable front and/or rear slippage via different slipper pads and clutch plates of different diameter, ensures more efficient and more consistent clutch operation to generate faster acceleration and less wheel spin.

For improved performance there are two different pad materials; yellow SLS pads with higher slippage and black medium hardness with less slippage. The slippage ratio between front and rear tires can be adjusted independently depending on the type of the track, tires and racing style.

The Multi-Adjustable Slipper Clutch is included in Carpet Edition.

Slipper Clutch Adjustments Xray XB4.

 

Central Gear Differential Xray XB4.

The central differential is now included in the Dirt Edition. The gear diff shares the same universal diff case and internal parts found in the front/rear differentials.

The maintenance-free, super-smooth gear diff has greater internal oil volume to increase consistency of the diff action and includes a composite case and cover with internal satellite gears that are precision-molded from special XRAY-developed graphite composite material, ensuring a long lifespan and super-smooth, efficient operation.

The differential outdrives are designed for use with 2.5mm driveshaft pins. The gear diff set includes an 81T spur gear and a 78T spur gear is available as an option.

The central differential is recommended for use on clay, bumpy Astro and low-traction tracks to increase traction.

I.S.S.™ Suspension Holders Xray XB4.

All-new front & rear suspension holders are redesigned along with the new HS bulkheads for an expanded range of set-up adjustments.

The rear suspension holders can be installed in upward or downward orientations, resulting in additional roll center locations for the inner hinge pins.

The downward orientation of the suspension holder is used primarily for Dirt tracks.

The upward orientation of the suspension holder is used primarily for Carpet tracks.

The suspension holders allow use of both the long or standard suspension arm configurations.

Machined from premium Swiss 7075 T6 aluminum and black coated.

Suspension Arms Xray XB4.

Carpet and Dirt editions include different suspension arms selected for their expected track conditions.

The Carpet edition uses the short suspension arms, while the Dirt edition includes the long suspension arms.

Rear suspension arms accommodate the multi-adjustable uprights. The outer pivot of each arm uses small screws to secure the hinge pins and prevent separation in a crash. This floating hinge pin reduces suspension bind.

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

There are two different suspension arms available: hard and graphite, each suitable for particular track conditions.

Shock Towers Xray XB4.

All-new front & rear shock towers are redesigned to accommodate the Horizontal Split Bulkheads (HS) and feature denser upper shock mount positions for more precise set-up adjustments.

The rear shock tower features extra roll center positions for precise set-up adjustment and extra wing mounting positions.

Both front & rear shock towers are machined from premium-grade graphite and are lightweight & strong, with multiple shock positions and roll center adjustment positions.

Shocks Xray XB4.

The front shock absorber bodies and shock shafts are shorter by 2mm. Combined with the new shock towers and suspension geometry, these changes increase stability and improve cornering speeds.

The big-bore shocks are membrane free, but still allow for easy, consistent building and rebound control using a bleed-screw shock cap design.

The aluminum body and lower cap are all machined from premium Swiss 7075 T6 aluminum.

The shock shafts are machined from special steel material, precision hand-ground for maximum smooth operation, and additionally hardened for increased lifespan.

 

Shock Springs Xray XB4.

Both Carpet and Dirt edition include shock springs selected for the specific track conditions.

There are two types of springs offered:

•​ Linear – The spring rate is constant during the entire spring compression. Springs with different linear 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 softer springs 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.

XB4 springs, like all other XRAY springs, are manually measured, selected, and matched into pairs to guarantee precisely equal length and damping characteristics.

Each spring is laser-engraved with stripes to indicate the firmness, the more strips, the stiffer the spring.

Battery Holder.

All-new tweak-free Quick Battery Holder allows for easy retainer height adjustment for more convenient battery mounting. The entire system is intended to reduce the effects of the battery and holder on chassis flex, making the XB4 more predictable and easier to drive.

The battery holder is universal for both Dirt and Carpet edition.

Side Guards Xray XB4.

Side guards are redesigned to accommodate the all-new Quick Battery Holder.

The side guards allow the servo mount to be connected to avoid any unwanted negative flex coming from the servo in very high traction conditions.

Tough composite side guards perfectly fit the chassis to seal against dirt and protect from side impacts.

Molded from a hard composite material, the side guards are an important part of the chassis flex adjustment for the majority of track conditions. For very-low-traction tracks, optional medium stiffness side guards are available.

To improve protection against dust, Velcro® double-sided tape is included to ensure a perfect seal of the body to the side guards, and to reduce the noise level of the running car.

Body Posts Xray XB4.

All-new rear body mount with more frontward position and updated to fit the new rear Horizontal Split Bulkhead (HS) and the new body. The shape of the holder allows for super easy access to the screws on the upper part of the bulkhead. Machined from premium graphite material.

Beefy 6mm thick body posts are made from a special composite material for maximum strength. The body supports are rounded to have a better fit and provide better support for the car body.

Steering System Xray XB4.

The dual arm steering system is simple yet effective, and features an easily adjustable integrated servo saver. Ackermann is easily adjusted by quickly changing the steering link mounting positions on the steering plate.

Bump steer is adjusted for more aggression by inserting a shim between the steering block and steering linkage.

High Traction Body Xray XB4.

The XB4’21 Carpet and Dirt Editions each feature new specifically designed XRAY Gamma bodies with super-smooth airflow and revised downforce characteristics fine-tuned for their intended conditions.

The Carpet edition of the all-new Gamma body is designed especially for high traction conditions and improves the stability in the fast corners, chicanes and improves rotation in tight corners.

The Gamma Carpet body is also available in lightweight version.

Low Traction Body Xray XB4.

The Dirt edition of the all-new XRAY XB4 Gamma body is designed for low traction conditions. The all-new design improves the stability and increases traction.

The Gamma Dirt body is also available in lightweight version.

Rear Wing Xray XB4.

The Carpet and Dirt Editions of the XB4 each feature and individually paired wing to work with their particular body. Made from strong Lexan™ material, the wing is supported on the wing mounts by extra flat shims to better support and extend the life of the wing.

Various wing designs in different thickness are available separately. The thicker wing gives higher traction and stability but gives reduced steering.

 

Anti-roll Bars Xray XB4.

Both Carpet and Dirt edition include anti-roll bars selected for their specific track conditions.

Anti-roll bars are manufactured from special spring steel material and are used to stabilize the front & rear ends of the car. The roll bars are easily mounted to the diff cases and can be adjusted with the linkages.

Front & rear anti-roll bars are interchangeable since 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 available separately for fine-tuning.

Multi-Flex™.

The XB4 incorporates the innovative Multi-Flex™ adjustment technology, which allows tuning of chassis flex for different track conditions.

Regardless of whether the track has low, medium, or super-high traction, chassis flex can be adjusted to suit track conditions to gain a competitive advantage.

Chassis Brace.

The optional front graphite chassis T-Brace is designed to increase front stability on high traction tracks and makes the car more predictable and easier to drive.

The rear graphite chassis brace is installed on the lower composite brace connected directly to the chassis. The brace reinforces the rear of the car and generates more stability while increasing traction.

The chassis braces are a vital part of the Multi-Flex™ adjustability.

Wheels.

The included wheels are IFMAR standardized with the new wheel hex offset. The wheels feature a redesigned countersunk center area to allow the wheel nut to sit deeper in the wheel.

The wheels are perfect for high-competition racing. They feature internal reinforcement ribs to provide stability and resist deformation, yet they are made from a flexible material to provide durability and withstand impacts.

The side of the wheel is aerodynamic for maximum performance. The wheels were designed to provide maximum traction.

The wheels feature a 12mm internal hex.

XRAY Instruction Manual.

The Instruction manual is universal for both Carpet and Dirt edition and features a list of any important optional parts suggested for fine set-up adjustments.

XRAY Instruction Manuals have become the industry standard, being simply the best manuals you will ever get with an RC model car.

Designing & Making of XB4.

Read the exclusive story about the designing and making of the XRAY XB4.

Development.

Successful development of the XB4 – like all other XRAY platforms – would not have been possible without the involvement of the entire racing team constantly working to test new ideas, prototypes, and improvements.

 

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 XB4 achieves a level of perfection in all details that is second to none.

Some information shown below may include details from previous kits,
and it may vary slightly from current kit specifications.

Gear Differential.

The front and rear gear differential features a split design of the cover and crown gear. The differential case has greater internal oil volume to increase consistency of the diff action, yet it is significantly narrower and to move the rotating weight closer to the centerline.

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

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

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 XB4 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.

Rear Uprights.

The multi-adjustable rear uprights allow for super fine tuning of the suspension geometry.

The upper roll center is adjusted at the camber linkage via shims (up/down & in/out), while the lower roll center is adjustable via eccentric inserts for 9 different positions (up/down & in/out).

The multi-function uprights have the upper roll center position in the middle of the axis of the driveshaft joint to help generate more traction and increase stability.

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

Motor Mount.

The motor mounting plate features a shape for easier access to the pinion gear set screw. The inner motor screw is recessed into the mount for improved clearance around the center spur gear.

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 still securely holds the motor plate using only a single screw.

To ensure the motor will not loosen in a serious crash or due to insufficient tightening, 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 vehicle.

Removing the motor or adjusting the gear mesh is easy and fast, with changes possible in only a few seconds.

Motor Bulkhead.

The lowered motor bulkhead reduced the CG of the motor and central slipper clutch/diff, improving cornering speed and stability.

Machined from the premium Swiss 7075 T6, the motor bulkhead is strong and lightweight.

Central Bulkhead.

The central assembly features a new upper top deck to match new layout of the motor mount and central bulkheads on the chassis plate. The entire assembly is more compact with weight placed as close to the chassis centerline as possible. The new upper deck also fits the optional central differential’s new case design and dimensions.

The graphite central upper deck holds ball-bearings in the motor mount and bulkhead assembly, while the upper deck allows easy access for slipper clutch adjustment.

Suspension.

The 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 and challenging features for a designer.

 

The 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 specially designed for the 1/10 off-road racing platform to provide responsive racing characteristics in all conditions. 

Servo Mount.

The servo mount has a more compact and stronger design. The servo mount is now secured to the side guard to eliminate any unwanted servo movement that can occur in very high traction conditions. The reduced deflection translates into more consistent and precise steering response while cornering. 

Wheelbase Adjustment.

Suspension arms allow for quick & 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 recommended for 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.

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 quick & easy lower roll center adjustment. With additional shims and extra inserts, fine tuning the roll center is easily achieved.

For maximum drivetrain reliability, larger 5x12 ball-bearings are used in the outer position with increased dynamic load. On the inner position, the smaller 5x10 ball-bearings are used for minimized unsprung weight. 

Caster Blocks.

The 1-piece caster blocks are very lightweight, yet the construction makes them very stiff and rigid. The non-adjustable caster angle is preset to 9°. Roll center position can be quickly & easily adjusted by inserting different thickness of shims atop the caster block (between the block and the vertical ball stud).

The non-adjustable caster is preset to 9°, however the position of the adjustable eccentric bushings in the I.S.S.™ suspension holders influences the caster as well. (For example, if the eccentric bushings have the roll center in middle position, the caster angle is 9° which when added to the 9° caster block gives a total of 18° caster. The total adjustability range for caster is 16-20°.)

Optional caster blocks with 6° and 12° built-in caster angles are available for further suspension geometry adjustment.

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

The new hard caster blocks increase stability in high-traction conditions, and help to increase cornering speed.

Drive Shafts.

The front and rear driveshaft lengths are updated to match the new differential width and suspension geometry; the front drive shaft is 83mm long and the rear drive shaft is 75mm long.

The safety collar on the front driveshaft secures the pin, while the ball bearing captures the pin in rear axles, both preventing the pin from coming lose during a run.

XB4 constant velocity drive shafts are manufactured from world-renowned HUDY Spring Steel™ and feature 2.5mm drive pins for maximum drivetrain efficiency. 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.

Ball-bearings.

All-new larger ball-bearing used in the rear uprights for increased reliability. The XB4 features greased ball-bearings for front steering blocks & rear uprights to increase lifespan in dusty conditions. The remaining bearings are degreased and oiled with AeroShell® Fluid 12 for maximum smoothness and long life.

A full set of high-speed ball-bearings are used throughout the drivetrain to ensure maximum efficiency.

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.

Shock Pistons.

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

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.

Wheel Hubs.

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, optional offset wheel hex drive hubs are available.

Electronics Plate.

A very handy, compact electronics plate allows for mounting the speed controller for quick & easy removal and assembly, and was redesigned to fit the new chassis and side guards.

Body Seal.

To improve protection against dust, Velcro® double-sided tape is included to ensure a perfect seal of the body to the side guards, to reduce the noise level of the running car.

Chassis Balance.

The 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.

Adjustment Possibilities.

The extensive and impressive 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 positions, bump steer, wheelbase, Ackermann, adjustable shocks, adjustable front and rear diff and adjustable XRAY Multi-Flex™.

Graphite Grease.

The XB4 includes premium #106210 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.
