XRAY X12 Platform.

Based on the ultra-successful X12 platform, XRAY proudly presents the all-new X12 which incorporates the latest improvements and refinements gathered by the team, race-proven in high-competition races around the world, and ready out-of-the-box to take you to the Winners’ Circle.

US Edition.

Since its debut, winning the ROAR National Championship title, the US team continues on-going development of the US Edition to ensure that the X12 will remain a top competitor on tight, technical, high grip tracks typically found in North America. All of the latest improvements tested by the team are incorporated into the all-new X12 US edition that recently won another ROAR title in the Modified class at the 2019 Indoor Nationals.

Made in Europe.

From the unique HUDY Spring Steel™ to the world's strongest Swiss 7075 T6 aluminum, along with XRAY's own secret composite mixtures, and the high grade graphite materials....every component on the X12 is premium.

Using these superior materials and crafted by XRAY's designers and engineers using state of the art German, Italian and Swiss CNC machines, the X12 is a blend of the world's finest."

European Champions.

XRAY X12 EU is currently the best-performing, most successful 1/12 pan-car in Europe. Alexander Hagberg continues his winning streak of European Championships in the Modified class making it 6 in a row: 2014, 2015, 2016, 2017, 2018 and 2019. XRAY X12 EU was designed for European tracks, designed to win.


Designed using some of the world's most sophisticated CAD tools, and manufactured using the world's best machining and molding equipment, the X12 achieves a level of precision in all details that is second to none.


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 artisan production specialists. The X12 is truly a masterpiece.

US & EU Edition.

With XRAY’s no-compromise, high-competition focus, the X12 was split into two different platforms, each optimized for different track conditions out of the box with no extras needed.

Whether on low to medium-grip tracks which are typical in Europe, or on super-high grip tracks which are typical in the US, there is an X12 to fit each occasion. Both choices are built on the same core platform with interchangeable parts.


Both the graphite and aluminum chassis have an all-new design and shape. The chassis was redesigned with a significantly narrower shape and repositioned side link mounting system that ensures that the chassis will minimize drag in high speed corners, improving the steering response and increasing high-speed steering.

The chassis includes an updated groove for the new battery backstop for a more secure battery mounting and adjustment in the most frequently-used cross-chassis position.

Side Link Mounting System.

The all-new chassis is so narrow that a completely new design of the side link mounting system had to be introduced. The new side mounting system features aluminum stands and graphite holders that have two different positions for pod link mounting.

Front Suspension Brace.

The all-new front suspension brace mounts across the lower suspension arms to help sharpen the steering response, improving the response to driver input upon entry in high speed corners. If the very direct feel is too much for certain track conditions or driver preferences, the brace can be removed for a more forgiving handling characteristic.

Shock Position.

The all-new front and rear graphite holders for the center shock absorber have new mounting positions, allowing for it to be mounted further back By selecting a longer or shorter shock, the damping and steering characteristics can be changed. The plates allow the shock to be moved front & back to alter how the car enters & exits corners. 

Frontward positions:
• Makes the car smoother
• More stable on-power
• Less sensitive to bumps

Rearward positions:
• Increases responsiveness
• Increases on-power steering

Long Shock:
• Shock built WITH adaptor (extension)
• Improves drivability over bumps
• Improves on-power traction

Short Shock:
• ​Shock built WITHOUT adaptor
• Improves steering response
• Quicker direction changes


Servo Holders.

The all-new servo holders have an additional hole to fit micro servos such as Sanwa SRG-HR and HS, while the standard positions still accommodate the standard 1/12 servo dimensions.

Suspension Concept.

To utilize the performance potential in various traction conditions, there are two different suspension concepts used on the X12.

The EU Edition includes a standard composite suspension that makes the car predictable and generates more traction.

The US Edition features unique graphite suspension arms that reduces torsional flex of the arms in the corners of very-high traction tracks, making the car more reactive and also stays flatter during cornering. 


The front upper arm is now moulded from a specially formulated graphite composite mixture that helps to increase steering and make the car more predictable.

The XRAY self-designed graphite front suspension was specially designed for high-traction US-style tracks. With the stiffer front, the car has more cornering speed while being easier to drive and more consistent in high-traction conditions.

The graphite arm is mounted on aluminum posts which are mounted to the chassis. The holder for the composite front upper arm mount is mounted on the graphite arm as well.

The graphite front suspension was successfully used by the US team to win the US National Championship title.

Pivot Brace.

The all-new lighter pod holder is moulded from a special composite graphite mixture that resists flex in high traction conditions making the car easier to drive. The material used also contributes to a freer movement of the center pivot ball during cornering.

Tweak-free lower pivot brace features nut groove where the nuts that connect chassis with brace will find the proper position by themselves so there is no need to reset the position for free movement when the pod plate is mounted.

The pivot ball is considerably lower and smaller than other pan-cars, thus reducing the weight. The pivot ball has an internal thread so there is no need for a locking nut, saving more weight but also allowing for greater side movement of the whole rear pod.

Battery Backstops.

The all-new graphite backstop for the cross-chassis battery alignment alternative is stronger than the previous composite brace for a more secure battery retention.

The all-new rear link brace & battery backstop allows for a wider range of battery placement adjustment.

The brace includes two holes into which the adjustable battery backstop is inserted. The battery backstop has 4 positions which allow the batteries to be moved more forward. The distance between each position is 2mm, so in total the battery can be moved up to 6mm more forward.


XRAY premium design, workmanship & material quality and its unmatched attention to detail through well thought-out refinements creates a car that is easy to drive, adjust, and maintain.


With countless wins in multiple classes at local, regional, national, and international levels, XRAY X12 is designed for highest competition racing and ready to win. Take your X12 to win your race.

Winning Heritage.

Team XRAY continues its winning streak at major international & national races all around the world! Just recently, Team XRAY added another European Champion and USA Champion titles to the already impressive list of achievements, which includes dozens of national titles from around the world, from the USA National Championship, and multiple wins at other famous races such as IIC, Snowbirds, and many others.

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

Rear Wheelbase Adjustment.

Both EU and US version of the X12 feature rear wheelbase adjustment. There are three different rear wheelbase positions available to choose from. There is the standard middle position, and also there are optional eccentric upper clamps to allow movement of the rear axle either 1mm forward or rearward depending on the clamp orientation.

A shorter car rotates faster in slow corners and has improved forward traction. A longer car is more free in high-speed corners and will feel more linear, especially during fast direction changes.

Upper Clamps.

The upper clamps work with the composite bushings to extend the life of the bearings as well as the durability of the clamps.

CNC-machined from premium extra-hard Swiss 7075 T6 aluminum and additionally black-coated for long life and stylish look.


The bulkheads work with the upper clamps with bushings as well with optional eccentric clamps.

The right bulkhead has a motor mount design with multiple motor mounting positions. The upper motor mount position prevents the motor from moving in serious crashes, and it adds another option to easily mount different types of motors.

CNC-machined from premium extra-hard Swiss 7075 T6 aluminum and additionally black-coated for long life and stylish look.

Rear Link Brace.

The rear link brace allows for a wider range of battery placement adjustment as well as featuring O-ring battery mounting system.

The brace features groves for the O-ring to prevent the battery from moving. This battery mounting system is more user friendly and battery tape is not needed anymore; it is very easy to remove or insert the battery.

The rear link brace features a narrow design that helps to move weight more into the chassis centerline, and give lower weight.

The graphite rear link brace holds the side tubes as well as the side springs and body posts, and works as a backstop for the battery pack.

Bumper Holder.

Redesigned bumper holder improves aerodynamics (mainly of lightweight body shells) as it prevents the front lip of the body from folding down at high speeds. It gives the body better protection in hard crashes.

Machined from premium 2.5mm graphite, the brace is flexible yet rigid enough to withstand serious crashes.

Gear Differential.

The optional XRAY self-designed, revolutionary, super-smooth gear diff is a direct replacement for the ball-differential.

Using the optional gear differential makes the car more stable and easier to drive, especially in high-traction conditions. The gear diff increases on-power steering which is needed on almost all types of tracks. A “must have” for every racer.

The complete gear differential set includes a composite case and cover, precision-molded internal satellite gears made from special XRAY-developed composite material, all ensuring long lifespan and super-smooth efficient operation. A super-strong hollow steel shaft ensures maximum reliability and strength.

The advantage of the gear diff is that it is 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 a superior sealing system.

Servo Mount.

The graphite plate posts and servo mount posts are 3mm shorter to allow the servo to sit lower to decrease the CG of the car.

When the inline chassis battery alignment is used, the included 3mm shims allow the plate posts & servo mounts to be raised so the battery can be placed below the graphite plate.

Side Tubes.

Lateral damping side tubes provide ultra-smooth side damping, making the car easier to drive and easier to work on. The outer aluminum tube and inner Delrin® tube operate ultra-smoothly. 

Side Shock.

Rear link pod upper plate includes a hole so an optional side shock can be mounted. The advantage of using the side shock is that it provides more traction in low-to-medium traction conditions.


The lower suspension arms feature smart eccentric aluminum inserts which allow quick & easy track-width changes depending on track conditions. Optional aluminum 0.5mm and 1.0mm eccentrics are used to set the track-width either narrower or wider.

Both EU and US Editions include specific track-width adjustment inserts.

Rear Axle.

To significantly reduce the rotating mass and improve steering, the original steel rear axle was replaced with a super-lightweight graphite rear axle.

The rear differential features high-grade precision carbide balls in the spur gear, hardened and precision-ground D-steel shims, and premium carbide axial thrust-bearing.

Rear Brace.

The rear graphite brace replaces the previous aluminum brace. The graphite brace significantly reduces tweak of the rear pod. To keep the lowest possible CG, the brace is positioned in the lowest possible position.

Machined from premium graphite, the brace is flexible yet rigid enough to withstand serious crashes. 

Rear Hubs.

The aluminum rear hubs are machined from lightweight aircraft aluminum, specially lightened and black-coated for stylish look. The rear left aluminum wheel hub features a center-balanced clamping mount system, ensuring secure mounting while eliminating vibration and run out.

Front Suspension.

Strong, simple, yet refined front suspension made from strong, lightweight, self-developed composite material. Tiny yet strong HUDY Spring Steel™ upper pivot balls ensure smooth, bind-free operation, while composite lower pivot balls allow the front suspension to operate even more smoothly. Fast & easy adjustment of front caster, front wheelbase, track-width, bump steer, roll center and ride height via included shims and clips. 

Super-smooth, hardened steel kingpins provide the foundation for the front suspension.

Wheel Axles.
Ultra-precise wheel axles CNC-machined from premium HUDY Spring Steel™ are additionally hardened and hand ground for precision fitment.

Adjustable Turnbuckles.Front upper 3mm adjustable HUDY Spring Steel™ camber turnbuckles are lightweight yet can withstand hard impacts, with precision threading to ensure fine camber adjustment. The 4mm adjustable steering turnbuckles are manufactured from lightweight aluminum.

Steering Block.

The tiny yet strong steering blocks have excess play removed for precise steering response. 

Front Wheelbase.

The X12 chassis features XRAY self-developed front wheelbase adjustment possibility. The chassis has two positions for front suspension mounting; the whole front suspension can be easily moved by 2mm frontwards or rearwards.

The long wheelbase is the same wheelbase as previous X12 cars, and is recommended for larger tracks or tracks with longer sweepers. A long wheelbase works well at low-to-medium traction tracks when more stability is desired. Also better suited to the Open Modified classes to make the car smoother and less twitchy.

The short wheelbase allows the car to rotate better in the middle of the corner to maintain cornering speed. Recommended for tight, technical tracks or tracks with numerous hairpin corners. The short wheelbase works well at medium-to-high traction tracks where a lot of steering is needed. Also better suited to the Stock and blinky classes

Reactive Caster.

Reactive caster is easily adjustable by using easy-to-change eccentric bushings of 2.5°, 5.0° or 7.5° (included). Reactive caster is used to adjust the amount of caster change when the front end of the car is compressing (diving) or decompressing (rising).

Front Ride Height.

The front suspension uses ride height adjustment shims for very quick, precise, and hassle-free ride height adjustment depending on track conditions. The set of 0.2, 0.4, and 0.6mm ride height adjustment shims are included for fine tuning.  

Camber Gain.

The upper arm shims allow for moving the front upper arm mount together with the upper arm more out from the lower arm, thus generating less camber gain and making the car easier to drive. With more shims, less camber gain is generated, reducing initial steering and giving less “twitchiness.”

Bump Steer.

3mm shims are included for the steering block to make the car easier to drive under high-traction conditions.

Servo Position.

Unique & innovative fully-adjustable servo mount allows easy adjustment of the servo position. The servo is attached to independent mounts that are inserted in a groove on the front upper plate. Depending on the size of your servo, you can easily install and adjust the servo and its position to the center of the chassis. By changing the orientation of the servo, you can adjust the weight balance of the car.

The floating servo does not touch the chassis, so it eliminates unwanted tweak and also allows you to adjust any servo to the centerline of the chassis. Smart and easy.

The optimal position of the servo depends on the weight of the electronics. If the car is heavier on the right side, a left-side servo position is used… and vice versa. 


The quick adjustable Ackermann positions can be adjusted by adding/removing shims between the servo and servo mounting posts. The composite shims included in the kit come in three different sizes: 3x6x1, 3x6x2, 3x6x3. Ackermann influences the steering of the car, and therefore it is important to make it an adjustable feature.

Servo Saver.

Tiny yet robust servo saver protects the servo from impact damage. Easy Ackermann adjustment is made via shims mounted below steering block pivot balls.

Shock Absorber.

The fully-adjustable shock features an aluminum shock body that is hard-anodized for ultra durability. The fine-threaded shock body allows for quick and easy shock spring preload adjustment.

Tiny, thin shock membrane gives smooth dampening characteristics, and a super-soft silicone shock O-ring gives super-smooth operation while preventing oil leakage.

The ultra-finely finished shock shaft with precise-molded composite shock piston ensures optimum shock oil flow and smooth shock absorber action.

The shock adaptor allows for quick & easy changes to the shock position. Using the adaptor allows for forward shock mounting position, and when the adaptor is removed the standard rearward position is used.

Weight Balance.

The layout of the electronics and position of individual sections of the car were designed with optimum weight distribution and balance in mind.

The steering servo is located in a lay-down position for lowest CG at the chassis center, and the layout of the chassis allows the batteries to be placed either cross or inline.

Depending on battery configuration, the ESC and receiver can be placed in various positions for ideal weight transfer and balance.

Battery Placement.

The position of the battery placement in the chassis has a significant influence on weight balance adjustment. To offer instant and comfortable weight balance adjustment - depending on various track conditions - the battery placement can be quickly changed from inline to cross-chassis. Smart and handy - an all-new unique feature and system.

Rear Ride Height.

The alu bulkheads allow for very quick & easy ride height adjustment. No more hassle to dismount the car to change the rear ride height! The included ride height shims are inserted between the bulkhead and upper bulkhead clamp to alter the ride height. Smart & easy.

The new method for ride height adjustment allows ultra-fine adjustment by 0.25mm increments, in comparison to the previous 0.5mm increments using eccentric bushings.

Side Springs.

Side springs are placed directly on the chassis for smooth and precise movement.

Spur Gear.

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.

Antenna Mount.

A tiny lightweight antenna mount secures the lightweight yet strong molded fiberglass rollover antenna which is available as an option #376310.

Foam Bumper.

X12 includes a foam bumper which improves the durability of the car and protects the front in hard collisions. Hand-cut from specially-developed foam material, the bumper is very light, yet very strong.

Body Posts.

Robust body posts with fully-adjustable body holders; optional super-fine +1 or +2mm body backstops available optionally for even more super-fine body height adjustment. 

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.


A full set of 10 high-speed, blue-sealed and steel ball-bearings are used throughout the drivetrain to ensure maximum efficiency. All of the bearings are degreased and oiled with Aero Shell® Fluid 12 for maximum smoothness and long life.

Premium Composite Parts.

All composite parts are manufactured by XRAY using premium self-developed composite mixtures which guarantee sufficient flex of the suspension parts, while being hard enough to withstand hard impacts.

Pivot Balls.

High-precision, HUDY Spring Steel™ upper pivot balls and composite lower pivot balls ensure smooth & precise movement of the front suspension.
