European Champions 2016 & 2017

Back-to-Back Champions

The 2016 European Championship was the first EC ever where the XRAY X1 dominated the race by placing 5 cars in the A-main, taking TQ honors, and having a double-podium finish (1st  and 3rd). The XRAY X1 the first-ever European Champion Formula car with Jan Ratheisky at the wheel.

In 2017, Team XRAY repeated the great success by bringing back-to-back European Champion titles back home, as well as having the most cars in the main final. Jan Ratheisky and Martin Hudy used 2018 prototype parts to dominate the race and take the podium win and 3rd place, respectively. It is the same out-of-the box X1 that you can purchase and race now.

Made in Europe.

From unique HUDY Spring Steel™… to world’s strongest Swiss 7075 T6 aluminum…, to XRAY’s own proprietary composite materials…, to premium high-grade graphite materials… everything on the X1 is exclusive and premium.

Using selected European exclusive materials crafted by XRAY’s engineering artists on state-of-the-art German, Italian, and Swiss CNC machines, the X1 is born from the finest that the world has to offer.

ETS Champions.

Back-to-Back Champions

With the most competitive Formula class racing series in the world – the ETS series – the pressure is high for dependable performance during the season at all the different tracks across Europe. With the world’s best drivers in the Formula class battling for the overall ETS season title, Jan Ratheisky has won the title for the past 3 years in a row (2014-2015-2016) with his XRAY X1, making the X1 the most winning and most successful Formula car.

Now the rest of the world can get and race the same ETS Championship-winning Formula car; trialed by fire and successfully proven in the most competitive racing series in the world.

Winning Heritage.

When it comes to high-competition racing there is absolutely no other Formula car that has more outstanding racing results and achievements. From national titles around the world, through IIC, ETS or Snowbirds national titles, to European Championship titles… the X1 has an astonishingly strong lineup of victories to support the winning heritage of the XRAY X1 platform.

Chassis Design.

The new super-narrow chassis is 24mm narrower compared to previous versions, eliminating contact with the track in corners while rolling and offering improved cornering speed.

The new chassis includes a slot for the composite battery backstop which allows 5mm battery position adjustment when using the most frequently used cross-chassis alignment configuration.

CNC-machined from custom-manufactured 2.5mm high-grade graphite material with a specially-designed compound for carpet racing and asphalt racing, the new X1 chassis allows the car to handle ideally on either indoor or outdoor tracks, on either carpet or asphalt. 


Chassis design, layout, and flex have significant influence on the handling of the X1. The final chassis design offers optimal stiffness for excellent handling, while still being flexible enough to generate maximum traction.

The super-narrow chassis front allows for maximum traction while having excellent steering and cornering speed. The chassis has ideal torsional stability to help eliminate the “scrub effect” in high-speed corners.

Optional aluminum chassis – available in either full stiff or flex version – allow you to tailor your X1 for particular track conditions. A 2mm graphite chassis for low grip asphalt tracks is optionally available.

Side Link Adaptors.

With the super-narrow chassis design, pod side link adaptors were changed from chassis mounting to graphite side link adaptors which are mounted to the chassis with shims and screws. The graphite plate includes 2-position for pod link mounting; outer position keeps the pod link straight, while the inner position allows for angled mounting of the pod links for improved in-corner steering. 

Steering Blocks.

All-new steering blocks incudes extra Ackermann position which provides more in-corner steering required mostly at asphalt tracks. The new position has a nearly 100% Ackermann curve to provide maximum steering characteristics.

The super-precise inner hole for the kingpin steel pin ensures wobble-free assembly.

Shock Adaptor.

All-new shock adaptor allows for a more frontward shock mounting position, and when the adaptor is removed the standard rearward position is achieved.

The new longer alternative position – which allows for lengthening the shock and mounting the shock on the graphite servo holder – improves drivability over bumps and improves on-power traction. This setting is recommended for low-traction or bumpy tracks.

The standard shock position improves steering response and is recommended for higher-traction tracks.

Shock adaptor allows for quick & easy shock position changes to adjust the downstop.

Servo Holder.

All-new graphite servo holder was redesigned to allow the mounting of the new shock adaptor, and thus offering the new long-shock alternative.

Pivot Brace.

All-new tweak-free lower pivot brace was redesigned for quicker & easier mounting of the pod plate on the chassis. Thanks to the nut groove on the brace, the nuts that connect the chassis with the 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 transition of the rear pod works via the pivot brace, which features an ultra-small and lightweight pivot ball for greater movement of the pivot brace. The pivot ball has an internal thread. 

Rear Link Brace.

All-new rear link brace has longer leads for battery side stops, allowing battery position adjustment on chassis by 5mm either more forward or more rearward while still keeping the battery securely in place.

The rear graphite brace allows the side tubes to be mounted on the car so that an optional side shock may be mounted as well. 

Battery Backstops.

The chassis features a new groove to allow revised mounting of the battery backstop and adjustment of battery position when cross-chassis battery alignment is used.

To eliminate battery movement when inline battery alignment is used, the chassis features holes for composite battery backstops

Battery Placement.

Battery placement on the chassis has a significant influence on weight balance. Battery placement can be quickly changed from inline to cross-chassis, to offer ideal weight balance depending on various track conditions. Composite battery backstops are included to eliminate battery movement.

Front Suspension.

Strong, simple, fully adjustable, yet smart & ultra-efficient front suspension consists of high-grade graphite lower & upper suspension arms, arm mount plate, and aluminum stands.

Steering blocks are made from strong, lightweight, self-developed composite material. Tiny yet strong composite pivot balls ensure smooth, bind-free operation.

Fast & easy adjustment of caster, track-width, roll center, camber, and ride height are done using included shims & eccentric bushings.

The anti-roll bar is adjusted on the upper graphite arms, and different thicknesses of wires are available optionally.

Caster is adjusted via eccentric bushings, offering 3°, 6°, 9°, and 12° settings.

Camber is adjusted via eccentric bushings, offering 1.0°, 1.5°, 2.0°, and 2.5° settings.

Front Track-Width.

The front track-width can be easily adjusted via the shims inserted between the wheel and the front suspension block. Shims for track-width adjustment are included.


Front camber is easily adjusted via front upper arm eccentric bushings.
The kit includes two eccentric bushings; by changing the orientation of the bushings, camber settings of 1.0°, 1.5°, 2.0°, and 2.5° can be achieved.


Caster is easily adjusted via front upper plate eccentric bushings.
The kit includes two eccentric bushings; by changing the orientations of the bushings, caster settings of 3°, 6°, 9°, and 12° can be achieved.

Roll Center.

Front upper & lower roll centers are easily adjusted via included shims. By changing the lower roll center position, the ride height of the car is adjusted at the same time.

Front upper arm roll center is adjusted by inserting shims atop the arm mount plate and alu stands.

Front lower roll center position/ride height is adjusted via shims inserted beneath the front lower suspension arm alu stands.

Ride height can be also adjusted via shims above & below the steering block on the kingpin axle.

Anti-roll Bar.

The all-new and innovative feature of the F1 class is the fully-adjustable wire anti-roll bar.

The anti-roll bar improves steering characteristics & precision, and makes the car easier to handle.

The wobble-free anti-roll bar system is mounted to anti-roll bar holders which are mounted on the arm mount plate via bearings for extra-smooth movement and quick & easy changes and adjustment. The roll bar turns in ball-bearings for maximum precision and free movement. Anti-roll bar height is adjustable via a ball screw.

The complete range of different anti-roll bar thicknesses is designed to work with the ball-bearing roll bar mounting system. A 1.2mm anti-roll bar is included as standard in the kit, and a full range of different anti-roll bar wires is available optionally. Anti-roll bars have laser-engraved stripes (corresponding to bar thickness) for easy identification.

Floating Servo System.

The floating servo system mounts the servo either completely independently from the chassis, or mounts it affixed to the chassis. The servo mounting method influences chassis flex and handling.

• Independent – more chassis flex, easier to drive, super-easy handling through curbs
• Fixed – less chassis flex, increased steering response, better high-speed steering

Floating Steering Arm.

The floating steering system allows the steering arm to be mounted either independently from the chassis, or affixed to the chassis. The steering arm stand mounting method influences chassis flex and handling.

• Independent – easier to drive over curbs & on bumpy tracks, helps prevent oversteer
• Fixed – increases steering response & precision

Servo Saver.

The tiny yet robust servo saver protects the servo from impact damage. The 4-spring servo saver gives precise steering, making the car easier to drive while giving consistent handling.

Steering Backstop.

The steering backstops mounted on the lower arms allow for the adjustment of maximum steering angle. The advantage of the backstops is that both steering sides can be adjusted to the same angle. Maximum steering angle can be adjusted depending on traction, surface conditions, and tires: under high-traction conditions, the maximum steering angle can be decreased to make the car easier to drive and eliminate traction rolling, or maximum steering angle can be increased for more cornering speed.


The front suspension assembly features composite pivot balls that allow the front suspension to work very smoothly. Super-smooth, hardened steel kingpins provide the foundation for the front suspension.

Wheel Axles.

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

Rear Suspension.

The rear suspension features a conventional rear pod that is adjustable via pivot-ball links, providing extremely easy assembly and tuning while being very effective and giving the highest competitive performance.

Rear Pod Upper Plate.

The rear pod upper plate is the base for the central shock, the platform for the side shock, and it connects the front chassis assembly with the rear pod. Machined from premium high-grade graphite, the pod plate is very strong and gives rigidity to the entire rear assembly.

The rear pod upper plate allows the side tubes to be mounted on the car and also allow an optional side shock as well. The design allows for easier mounting/dismounting of the center shock.

Side Damper Tubes.

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

Side Shock.

The rear pod upper plate and rear link brace allow for mounting of an optional, ultra-precise micro-size side shock which is machined from premium Swiss 7075 T6. The side shock is silicone-oil filled to ensure constant & ultra-smooth damping. The side shock delivers maximum traction, especially in low-to-medium traction conditions.

Available as option only #378100


Side Springs.

Side springs are placed directly on the chassis for smooth and precise movement. Straight side springs have more consistent and smoother compression for smoother out-of corner exiting, and reduction of traction rolling. Optional side springs are available.


Rear pod bulkheads are CNC-machined from premium extra-hard Swiss 7075 T6 aluminum, additionally black coated for long life and stylish look. The bulkheads are strategically machined to reduce weight to minimum while retaining strength.

Motor Access.

The rear pod accommodates all motors. The open-top design of the rear pod left-side bulkhead provides super-easy motor access.

Rear Axle.

The ultra-strong lightweight steel axle is used to provide maximum reliability even in serious crashes. The rear axle is hollow for lightest weight while still ensuring maximum strength. The rear differential features high-grade precision carbide balls for spur gear, hardened & precision-ground D-shaped steel shims, and premium carbide axial thrust-bearing.

Spur Gear.

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

Rear Wheel Hubs.

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

Rear Ride Height.

Ride height is easily adjustable using included eccentric rear axle bushings, as well as adjustable shock preload for middle ride height adjustment.


The X1 features XRAY short shock from the T4 touring car platform. The unique XRAY aluminum shock absorber has interchangeable internal parts, with fixed 1-piece precision piston which is available with 3 different-diameter holes for damping adjustment: 3 or 4 holes with 1.1, 1.2, or 1.3mm diameter. No matter what you choose, all pistons are ultra-true and round due to a very special mould design, resulting in ultra-free movement of the piston inside the shock body.


The aluminum shock body is machined from Swiss 7075 T6 for maximum strength and rigidity.

The shock cartridge has been designed for a self-centering shim to hold silicone O-rings, guaranteeing perfect alignment in the shock body. A finely-threaded aluminum shock lower cap secures the silicone O-rings and shims in the shock body.

A finely-threaded spring preload collar is used for quick & easy spring preload adjustment.

The upper aluminum cap features a small vent hole which makes shock assembly very predictable and easy, since excess shock oil will escape through this vent hole to ensure that the proper amount of the oil remains inside the shock assembly.

A super-soft silicone membrane – supported by a miniature foam pad (inserted inside the membrane) – provides proper damping characteristics.

Progressive Shock System.

The X1 shock allows the use of well-proven optional Progressive Shock System (PSS™) inserts which generates even more traction and steering and is a highly-recommended option part for asphalt surfaces.

The shock insert has 3 triangle cuts and is used with piston without holes. The hardness of the shock is influenced not by the holes in the piston but by the insert. The insert is mounted into the shock with the wider surface on the bottom of the shock and narrower on the top.

When the piston is at the bottom of the shock, it moves softer and dampening becomes harder when the piston is going to the top. This means that the shock dampening is softer in the first part of movement and becomes harder when the car is moving more.

Available as option only #308039 - Alu Progressive Shock - Set (2)


Shock Spring.

To make the car more stable and easier to drive under various track conditions, the new 3S 2.3 linear spring was chosen as the basic setting to provide the best balance between traction, stability, and steering response.

A complete range of optional 3S springs either linear or progressive are available for further fine adjustment.


Steering linkages consist from adjustable 3mm turnbuckles manufactured from lightweight Swiss 7075 T6 aluminum which are used to adjust front toe.

High-Grade Graphite Parts.

All graphite parts are CNC-machined from custom-manufactured 2.5mm high-grade graphite material with a specially-designed compound for carpet racing and asphalt racing, the X1 handles ideally on either indoor or outdoor tracks, on either carpet or asphalt.

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.


A full set 11 high-speed, blue-sealed, steel ball-bearings are used throughout the drivetrain and steering to ensure maximum efficiency. All bearings are degreased and oiled with AeroShell® Fluid 12 for maximum smoothness and long life.

Body Posts.

Robust body posts have fully-adjustable body holders and are rear posts are mounted on the solid graphite platform on alu stands.

Front Spoiler.

The front spoiler consists of two parts: a composite bumper and a Lexan™ downforce spoiler.

The composite front chassis bumper is very rigid yet flexible, and provides protection where the car needs it most… in the front corners of the chassis where damage may occur from impacts.

The lightweight Lexan™ front spoiler is mounted to the composite front bumper and provides the necessary aerodynamic characteristics. There are two types of spoilers included: low downforce & high downforce, and each are used in particular track conditions.

Rear Wing.

The adjustable rear wing allows for easy adaptation to varying track conditions. The highly-efficient rear wing works together with the X1 racing body, which has air flow channels to direct air onto the wing to help generate rear traction and stabilize the car in chicanes.

The rear wing mounting system features a graphite mount and aluminum stands. Using composite shims between the wing and the alu stands, the wing position can be easily adjusted. The height of the rear wing can be adjusted by changing the mounting position on the graphite plate.

Rear Graphite Wing Mount.

The all-new rear graphite wing mount has a new design which allows higher or lower mounting of the rear wing to adapt to traction, conditions, and racing surfaces.

When traction is very low (mainly on asphalt surfaces) the upper holes allow a higher wing mounting position to generate more stability and traction off-power.

When traction is very high (mainly on carpet surfaces) the lower holes allow a lower wing mounting position to decrease traction rolling and make the car easier to drive.

Machined from premium 2.5mm graphite material.

X1 Body.

This high-performance, low-profile aerodynamic body was designed to perfectly fit the X1 and to work under all track conditions while keeping the coveted F1 look and style.

The front and rear of the body have been designed to provide balanced downforce for maximum stability and directed airflow onto the rear wing. The body & cockpit sides are as flat as possible to direct airflow around the body for maximum stability. The body is made from high-quality premium Lexan™ material.

The integrated helmet ensures the body is legal for races where a pilot figure helmet is required.

XRAY Orange Color.

Most aluminum parts are orange anodized for a very distinctive XRAY design look. The combination of traditional XRAY’s orange and black coloring gives the car the perfect look and appeal. Color may slightly vary.

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.
