XRAY 1/10 X4 24 Graphite Edition 4WD Electric RC Touring Car Kit - XY300038

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 trademark attention to detail by our production specialists. The X4 is truly a masterpiece.

Chassis

There are two chassis alternatives to choose from when selecting your X4’24:

The 2.2mm graphite chassis is CNC-machined from premium-grade material. This chassis is developed for all asphalt conditions. The narrow chassis is only 84mm wide with a variety of chassis flex adjustments that help to generate exceptional traction and give excellent steering characteristics.

The 2.0mm aluminum flex chassis is CNC-machined from premium Swiss 7075 T6 aluminum and then black coated. The narrow chassis is also 84mm wide and features special cut outs that provide the desired chassis flex characteristics. The bottom edge of the chassis is tapered to reduce contact between the chassis and the ground to improve cornering speed.

Suspension

The X4’24 suspension components are completely redesigned with improved inner shock position with ultra-low CG. This new configuration uses new lower & upper arms, new upper clamps & lower bulkheads, new anti-roll bars, steering & ARS plates and new shock holders.

Suspension Arms

The completely redesigned upper & lower CFF™ suspension arms are the foundation for the new inner shock mounting system ultra-low under arm anti-roll bar mounts and fully updated geometry. The new suspension arms greatly improve flex and twist under dampening. With the shock mounted on the inside of the arm, the load is more evenly distributed through the suspension arm, increasing the mechanical traction and responsiveness of the car.

The re-designed location lowers the shock 4.5mm to reduce the CG and improves cornering speed and stability. These changes make the X4’24 easier to drive and more resistant to traction rolling in high traction conditions. More centralized weight also improves tire wear and controls tire temperatures.

The CFF™ style of arms provide extremely responsive and sharp handling, generating great cornering speed & traction. The result is great drivability that is critical for improved lap times.

XRAY has specifically chosen different arm hardness to include in the graphite and aluminum versions of the X4’24 for the best possible out of the box performance on their intended surfaces.

X4’24 Graphite Edition include Medium suspension arms

X4’24 Aluminum Edition include Hard suspension arms

Upper Arms

The new upper arm shape conforms around the inner shock position for proper clearance without compromising strength and improve steering and both forward traction and lateral grip. The updated design also improves durability and eliminates radial play for maximum precision and control from the upper arms.

The graphite and aluminum versions of the X4’24 come with specifically chosen hardnesses of suspension arms to match the typical conditions, and both are compatible with all X4’24 arm options for additional tuning versatility.

X4’24 Graphite Edition includes Soft upper arms

X4’24 Aluminum Edition features Medium upper arms

Inner Shock Mounting

All-new inner shock mounting locations improve the rolling characteristics & cornering consistency, as well as optimize flex and reducing twist under dampening. Front suspension moves the shock position behind the drive shafts for more precise steering response and improved steering characteristics. Rear suspension moves the shock position in front of the drive shafts for improved traction.

Shock Holders

Versatile new shock holders use shims for adjusting the shock position in more precise shock angle increments. The rear shock holder offers an Active or Fixed dampening setting in addition to the shock angle. All shocks are located 4.5mm lower, improving CG, cornering speed and stability, while also making the car easier to drive and more resistant to traction rolling.

Simplified shock mounting uses a captured mounting stud secured to the shock holder with a special setscrew. It is not necessary to use thread lock as the setscrew will keep the stud secure even during shock install/removal.

Rear Active Dampening Cornering Effect

All-new rear shock holders offer Active or Fixed dampening setting alternatives. The Fixed setting is the traditional shock mounting method, while removing the M3x8 screw allow the Active holder bracket to pivot, softening the rear suspension dampening to improve off-power steering and increase rotation in high traction conditions.

Shock Holders Flex Settings

Front & rear shock holders have three different mounting options for different chassis flex alternatives. The flex options have a significant impact on handling and are used to fine-tune handling for different conditions.

Upper Clamps

Heavy duty upper clamps improve durability in hard crashes and accommodate the new inner shock mounting system. Redesigned heavy duty upper clamps improve durability in hard crashes and accommodate the new inner shock mounting system. The upper clamps use caster inserts for quick and easy set-up changes, and feature centering pins for precise installation and improved crash reliability. The screws installed from the bottom of the caster inserts capture the inserts in the upper clamps to secure the inserts while servicing the car. The screws also serve as the upper arms pivot ball mounts, reducing the number of components in the assembly and reducing weight. The upper clamps and caster inserts are made from premium Swiss 7075 T6 aluminum and black anodized.

Motor Mount

The new motor mount features 3mm centering pins instead of 2mm, for improved durability in serious crashes. The motor mount features an extra front attachment point developed for US black carpet, improving the stability and consistency of the car in these high grip conditions.

A new cutout provides additional clearance for speed controller wiring that improves the look and cleanliness of the electronics installation.

The top deck mounting holes’ depth is reduced to allow top deck to have an improved flex effect.

Motor Mount Flex Adjustment

The motor mount is a vital part of the X4 Multi-Flex settings. The motor mount attaches to the chassis using various combinations of five possible screw locations. Two are placed in front of the layshaft axis and the other three screws are located to the rear. Up to four screws can be removed for chassis flex adjustment.

Steering & ARS Plates

Updated front & rear steering plates work with the new arms and shock positions. The new steering plates move the Ackermann position further out for more precise car control and make the X4’24 easier to drive. The ARS plates move the toe link mounting position further forward for improved rotation in high traction conditions.

Anti-roll Bars

The ultra-low CG anti-roll bars are attached from below the suspension arms with considerably reduced mounting hardware and material. The wobble-free anti-roll bar height is easily & comfortably adjusted via set screw from top of the arm.

The included anti-roll bars were chosen specifically for the typical conditions found when using the graphite and aluminum versions of the X4’24 for the best possible performance out of the box.

X4’24 Graphite Edition includes 1.2mm front and rear anti-roll bars.

X4’24 Aluminum Edition includes 1.3mm front and 1.2mm rear anti-roll bars.

The anti-roll bar pivots in ball-bearings for maximum precision and free movement. The complete range of different anti-roll bar thicknesses is designed to work with the ball-bearing roll bar mounting system. Anti-roll bars have laser-engraved stripes (corresponding to bar thickness) for easy identification.

CFF™ Arms

The unique CFF™ upper & lower suspension arms are an elegant engineering achievement that look great and perform even better on the track. Using XRAY’s own newly developed manufacturing process, a carbon fiber arm and composite arm are molded together using a fusion process to produce a single CFF™ suspension arm.

The benefits of the CFF™ arms are tremendous. The thickness of the inner carbon fiber plate determines the hardness and flex of the arm. The composite around the carbon helps control its flex and rebound, resulting in a very consistent feel from corner to corner.

Medium and hard versions are available to tune the X4 handling to different track conditions.

Suspension Mounting

Thanks to the unique design of the CFF™ arms, all the suspension components are mounted directly on the arm without additional brackets, bushings or extensions. This direct mounting eliminates unwanted play between these extra components. Most importantly, the reliability and accuracy of the direct mounting ensure that settings remain consistent during a run even after a crash.

Spring Clip System

The all-new SCS – Spring Clip System allow for super easy, fast and simplified installation of the wheel hubs on the drive shafts. Now it takes just one click to install or remove the wheel hub and you can forget about the hassle with the outer C-clips. Smart & easy.

Rear Hub Height Adjustment

The kit includes two different pivot ball lengths of 5.5mm and 6.5mm for different rear hub height adjustments. The 6.5mm long pivot ball with 1mm extra thread length is suggested when using more than a 0.5mm hub height shim to improve the durability of the rear hub in serious crashes.

Wheel Hubs

The included wheel hubs work with the SCS - Spring Clip System for simplified installation. Narrow hexes are included to reduce the car width and increase steering and traction.

Graphite composite front and rear hubs provide the proper suspension geometry for improved steering and traction. The hubs contain small size bearings and a drive axle that moves the driveshaft pivot point deep into the hub, in line with the hub’s rotational axis between the upper and lower arm. This alignment improves driveline efficiency and handling. The ultra-narrow wheel hubs are lightened for reduced rotating mass.

The hubs allow full adjustability of the axle height to adapt the car to every condition. The design of the hub is universal with the same part used at all four corners with corresponding extensions. The aluminum front steering plates and rear ARS plates are easily mounted depending on the hub’s location.

XLP Shock Parts

All the XLP shock parts are specifically designed for the smallest possible size to reduce the weight and keep the lowest possible CG.

Shock bodies are CNC-machined from premium Swiss 7075 T6 aluminum and hardened to ensure the maximum lifespan. The aluminum upper and lower nuts have a low-profile design, including sealing O-ring and upper composite ball joint. The shock shaft, shock adjustable nut, spring retainer and pivot balls are designed to achieve the lowest shock height possible.

The included shock pistons sets are 4-hole pistons with 1.1 and 1.2mm diameter holes. The pistons are molded using a special process and composites to ensure extreme roundness while maintaining maximum stiffness and durability. 

XLP Shock Springs

The included XLP series of springs are 3mm shorter than the ULP ones, to match the XLP shock length and provide the correct rates and ride height. They are available in a full range of rate choices including 3 alternatives of progressive springs C2.4-2.7, C2.5-2.8 and C2.6-2.9.

The X4’24 stock shock springs offer versatile out of box performance for many conditions. The most popular C2.5-2.8 in front and C2.6 in rear are included in the kit.

All XRAY springs are manually measured, selected, and matched into pairs to guarantee precisely equal length and damping characteristics.

Caster

The most frequently used 2 dot caster inserts are included for the front, with the 3 dot inserts for the rear.

Aluminum inserts easily set the caster angle for quick and accurate tuning, and in the rear suspension, the inserts can be reversed for even more adjustment possibilities.

Gear Differential

The gear differential includes steel diff outdrives for the BB drive shafts. The X4 gear diff produces the on-power steering that is needed on nearly all types of tracks, and is ideal for both carpet and asphalt tracks.

The gear diff includes a composite case and cover with the integrated pulley. The internal gears are precision molded from tough composite material and combined with aluminum drive shaft adapters to create a light and super-smooth differential.

Another key advantage of the gear diff is that it is virtually maintenance-free. 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 the superior sealing system.

Solid Axle

The solid axle features steel diff outdrives for BB drive shafts.

Solid axle pulley position has the front belt alignment to match the center layshaft for improved consistency and forward traction.

Top Deck

2pcs split top decks are included in the kit to improve steering and traction in most conditions.  The graphite version for asphalt tracks includes the open top deck in the front, the aluminum versions for carpet tracks feature the top deck with special wave shape connection in front that reinforces the flex of the front suspension without a completely rigid connection which improves stability and consistency.

The 2pcs top decks are reinforced around the motor mount screws area and the groove in the front top deck is thinner to add more material for improved durability.

The Multi-Flex™ top deck has a narrow shape for easier installation, improved handling characteristics and features several different flex options out of the box using top deck screws.

The machined ultra-precise top deck screws ensure the top deck is mounted completely tweak-free to improve the flex characteristics.

Made from 2.0mm graphite material, the shape of the top deck has been specifically designed to achieve maximum traction and great steering characteristics at the same time. Optional 1.6 top decks are available for low to medium grip carpet conditions.

Top Deck Multi-Flex™ Settings

The top deck flex settings allow quick and easy adjustment of chassis stiffness in 3 different alternatives.

Battery Backstops

The X4 motor mount has two integrated and adjustable battery backstops to precisely set the battery offset from the center of the car. The battery backstop system is designed for use with the increasingly common shorty batteries as well as standard packs.

The battery backstops prevent the batteries from moving in a crash and interfering with the spur gear on the center layshaft.

Belt Tensioners

For maximum drive train efficiency there are two ball-bearing equipped belt tensioners integrated in the motor mount’s battery backstop components. The two tensioners are individually adjustable to control the tension of the front and rear belts independently.

Middle Layshaft

The all-new aluminum layshaft is strategically CNC-machined to minimize rotating weight without compromising strength or integrity. The hollow layshaft is perfectly round with zero run out, reducing drivetrain vibration.

The lay shaft is machined from premium Swiss 7075 T6 aluminum and then black coated.

The composite belt pulleys key solidly to the layshaft, and the completed assembly is installed onto the motor mount’s steel layshaft axle.

Motor Mount Brass Weight

Smart design of the motor mount includes locations to install optional #309852 nickel coated brass weights specifically designed to fit around the driveline components and place the weight near the vehicle center.

Centering Pins

All chassis mounted aluminum framework parts including the bulkheads, motor mount, servo holder, front shock towers and rear body post plates feature centering pins for easy assembly and maximum reliability in a crash.

Spur Gears & Pulleys

Precision-molded spur gears are made from XRAY's exclusive composite material, ensuring true running, super-quiet operation, and robustness for handling powerful motors. A range of optional spur gears for fine tuning is available.

Steering System

The X4 steering system is designed for the best possible steering characteristics and cornering speed. The steering plate has optimized positions for the links and sits close to the chassis. The steering posts are short to reduce the flex in the steering system for more precise reactions to inputs. The steering system also features a shim on the bottom of the plate for easy adjustment of the steering lock angle. The aluminum steering arms are included as standard in each X4 kit.

The dual-arm steering system is supported by six ball-bearings and rotates on aluminum posts. Ackermann is easily adjusted by inserting shims between the steering plate and ball ends for the steering rods. The low position of the steering linkage gives the car improved handling going through the corners.

Servo Mount

Universal reversible servo mount fits all standard servos without extra parts, with the choice of front or rear position to adjust the chassis flex and steering feel for different conditions.

T-Brace

The optional T-brace mounts to the chassis just in front of the rear suspension and makes the car more stable, generates more rear traction, and allows for some chassis flex adjustments to alter steering characteristics by adding and removing screws from the brace.

Servo Saver

The XRAY servo saver has become the industry-standard saver and remains unchanged and is included in each X4 kit.

Several linkage mounting positions are offered to make the steering linkage adjustment easier. The servo saver consists of 4 springs which makes the servo saver strong enough to provide the precise steering racers demand, while still being flexible enough to prevent servo damage in hard crashes. The servo saver has interchangeable bushings to fit most popular servos.

Bearing Holders

Both front and rear bulkheads feature additional integrated belt-tension adjustment through the use of adjustable bearing eccentric holders. These holders are also reversible to move the differential height from the lower or upper position that is now +1mm higher than the T4 platform.

Special Hardware

To ensure maximum performance, the X4's high-precision pivot balls are machined in-house and then black coated or nickel coated for a smooth and long lasting finish. To maintain proper balance through every run, the in-house machined top deck screws ensure tweak free handling from start to finish.

Drive Belts

The 2-belt 4WD drivetrain concept provides maximum efficiency featuring 3mm narrow front and rear drive belts that have been specially ground for minimal thickness and maximum flexibility.

Ball-Bearings

A full set of 25 high-speed, blue-sealed and steel ball-bearings are used throughout the drivetrain, steering and anti-roll bars to ensure maximum efficiency. All of the bearings are degreased and oiled with Aero Shell® Fluid 12 for maximum smoothness and long life. The bearings used in steering blocks and uprights have been specially selected to reduce unsprung weight and maximize drivetrain efficiency.

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.
