Back-to-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 is the first-ever European Champion Formula car with Jan Ratheisky at the wheel.

In 2017, Team XRAY repeated this 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, take the podium and win 3rd place respectively. It is the same out-of-the box X1 that you can purchase and race now.

In 2018, Team Xray repeated the success and won the European Champion title for the 3rd time in a row. Jan Ratheisky used the 2019 prototype parts such as the wider front-width setting and the new top deck.

Back-to-Back Champions

With the most competitive Formula class racing series in the world – the ETS series – the stakes are high for dependable performance during the season at all 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) and he reclaimed his title in 2018 with his XRAY X1; making the X1 the most winning & successful Formula car.

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

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

The all-new front lower arms were redesigned for increased durability, easier drivability in high-traction conditions and increased adjustment possibilities.

The shape of the arm was redesigned to be more robust for improved durability of the arms. The extra material reinforces the arm and prevents it from bending in hard crashes.

The graphite material hardness was changed to a stronger compound to reduce flexing of the arm. This results in increased stability for the car and easier drivability in high traction conditions.

The front lower arm features two mounting positions which allow adjustment of the car’s front width.

The softer front lower arms from previous X1 versions are still available options and are recommended for use on low-traction tracks or harder front tires to generate more steering.

The X1 kit features two arm mount plates with standard and wider design options.

The narrow arm plate is used with the narrow lower arms setting and is for the most common F1 tires such as HUDY.

The wider arm plate is used with the wider lower arms setting and is for compatibility with narrower tires like Volante.

The arm mount plate is precision machined from premium 2.5mm graphite material. It holds the front aluminum anti-roll bar holders as well the eccentric suspension holders.

The all-new servo mount was redesigned to work with the new lower adjustable graphite arms.

The servo mount is CNC-machined from premium extra-hard Swiss 7075 T6 orange-coated aluminum for a stylish look.

The all-new unique top deck allows for adjustment of the car’s flex using the In-Line Flex™ for different traction conditions and tires. The top deck also features a mounting hole for the shock adaptor when the long shock setting is used.

There are three In-Line Flex™ options: Soft, Medium and Stiff.

The all-new plate for mounts was redesigned to connect with the new In-Line Flex™ top deck; allowing for super easy and quick chassis in-line flex adjustment. The plate is made from high-quality 2.5mm graphite material.

All-new rear alu bulkheads were redesigned to work with the new upper clamps with bushings alongside optional eccentric clamps.

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

The tiny rear bulkheads, including the upper bulkhead clamps, are significantly lower and lighter which helps to reduce CG of the rear suspension.

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

The upper clamps were designed to work with the new rear bulkheads. The composite bushings extend the life of the bearings & durability of the clamps.

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

X1 features an all-new rear wheelbase adjustment with three different rear wheelbase positions available to choose from.

The standard middle position with optional eccentric upper clamps allows movement of the rear axle either 1mm forward or rearward depending on the clamp orientation.

The shorter car rotates faster in slow corners and has improved forward traction.

The longer car is freer in high-speed corners with a more linear feel; especially during fast direction changes.

The all-new rear graphite mount plate was redesigned to work with the new bulkheads and features 2 new extra-high wing mount positions to generate even more traction. The mount also features two holes that allow for mounting of an optional fan.

The rear graphite wing mount has multiple high and low mounting positions to adapt to many traction conditions and racing surfaces.

Upper holes – for higher wing mounting to generate more stability and traction off-power. Recommended for very-low and low traction conditions; typically on asphalt.

Lower holes – for lower wing mounting to decrease traction rolling and easier car drivability. Recommended for high and very-high traction conditions; typically on carpet.

The all-new alu bulkheads allow for quick & easy ride height adjustment. No more hassle of disassembling 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 ultra-fine ride height adjustment allows changes in increments of 0.25mm in comparison to the previous 0.5mm increments using eccentric bushings.

The all-new rear link brace was completely redesigned to allow for a wider range of battery placement and features a new O-ring battery mounting system.

The brace features grooves for the O-ring to prevent battery movement. This battery mounting system is more user friendly for easier insertion and removal of the battery with no more need for battery tape.

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

The softer, most commonly-used front coil springs are now included in the kit to make the X1 even better out of the box. These silver C2.0 springs are the most used springs for both carpet and asphalt tracks and improve corner-steering.

The revolutionary, all-new XRAY- designed, 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, cover and 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. For a very long period of time, when the diff is correctly built, there is no need for maintenance or frequent oil changes plus no leakage due to the superior sealing system.

Since the release of the first X1, the competition level of the Formula class continues to rise so it’s no surprise that Team XRAY continues to drive development and push performance boundaries.

They are the driving force for ongoing detail refinement that make the X1 the best handling and performing 1/10 Formula car in the world.

As with every XRAY platform, the X1’s success is based on the R&D and Factory Team members’ passion that furthers development and puts out maximum effort at worldwide race events for winning results and constant support to our customers. Jan Ratheisky is the XRAY R&D expert responsible for the X1 platform; traveling around the world not only to showcase the performance of the X1 but to also be available to service and help all XRAY customers. True passion is what drives Team XRAY.

The 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 chassis includes a slot for the composite battery backstop which allows 6mm 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.  New 2.5mm chassis made from harder graphite material was developed for very high traction conditions or for tires that offers a lot of steering which makes the car more difficult to drive. This chassis makes the car more stable and easier to drive and eliminates oversteering problems.

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-positions 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.

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.

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

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.

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.

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 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.

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.

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.

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.

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.

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.

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

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.

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.

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. 

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 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.

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

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.

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.

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.

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.

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)

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.

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.

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.

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

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.

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.

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.

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.
