XRAY NT1 Platform Designer


Since the release of the first XRAY NT1 nitro touring car, XRAY has been a driving force in the 1/10 nitro touring car racing scene. Continuous development and evolution of the XRAY product line has lead to ever-increasing performance.

Made in Europe.

Designed, developed, and fully manufactured in-house at the XRAY factory in Slovakia, Europe, using the most high-tech German & Swiss machines and premium European materials, crafted with XRAY’s legendary attention to detail by our artistic production specialists. The NT1 is truly a masterpiece.


At the heart of XRAY’s philosophy it is a firm commitment to perfection when it comes to engineering, design, performance and support, all made possible by state-of-the-art in house manufacturing.

Premium & Exclusive Materials.

The NT1 is luxury model racing car and as such features only the finest, most premium materials: premium woven graphite – exclusive top-secret HUDY Spring Steel™ – high grade Swiss 7075 T6 – high-tensile heat-treated steel and aircraft aluminum – and XRAY’s self-developed and formulated composite compounds. All is premium and unique on the NT1.

Black Design.

All-new black anodized bulkheads.

2-speed Carrier.

All-new 2 speed carrier with ribbed profile for improved, more consistant shifting. Machined from lightweight Swiss 7075 T6 aluminum.

Drive Flange.

All-new lightened drive flange with one way bearing. The lightweight design reduces rotating mass to improve the drive train efficiency.

Brake Disc Adapter.

All-new brake disc adapter is lighter by 25% to reduce the rotating mass for faster acceleration and improved braking response.


The chassis works together with the rear bulkheads, rear arm mounts, and front brace to create the flex adjustments to easily tune for varying traction levels or change handling dynamics. The chassis plate features a larger rear window for improved flex characteristics, and a revised mounting location for the front brace to simply installation and maintenance.

The lightweight chassis is CNC-machined from premium Swiss 7075 T6 aluminum, strategically machined in low-stress areas to make it as light as possible without adversely affecting strength or rigidity.

Front Chassis Flex Adjustment.

The updated front brace mounts directly to the chassis plate, separate from the servo saver, for easier installation.

Using the aluminum brace increases steering response and cornering speed; without the aluminum brace, the car is easier to drive and has more forward traction.

Rear Flex Adjustment.

The NT1 features rear flex adjustment. The chassis and rear bulkheads were redesigned in the way that allows two different flex settings that help to adapt the car to different tracks and traction conditions. There are two options to choose from:

SOFT – Steel spacers are not used. The rear bulkhead extensions are not connected to the chassis, allowing more flex to generate more rear grip. Recommended for tracks with lower traction levels.

HARD – Steel spacers installed. The rear bulkhead extensions are connected to the chassis using the spacers inserted between them. By increasing rear chassis stiffness, this setting decreases the rear grip but increases off power steering and rotation in the corners. Recommended for tracks with higher traction.

Rear Suspension Multi-flex™ Technology.

The rear suspension design features Multi-Flex™ quick adjustment to easily adapt the handling of the car to track conditions and tire options. There are three different flex characteristic choices.


Steel spacers and bracket bushings are removed. This allows maximum flex of the rear suspension and generates maximum rear traction. Recommended for low-traction tracks, or spec tire races that require larger diameter or harder handout tires.


Steel spacers are installed between the rear bulkheads and the chassis plates, but the bracket bushings are removed. This reduces the flex of the rear suspension and improves out-of-corner steering and rotation of the car, but also slightly decreases rear traction. Recommended for medium-traction tracks, or races allowing softer spec tires.


Steel spacers and bracket bushings are installed. This connects the entire rear suspension together, creating a stiff framework that creates more rotation and improves corner exit steering. Recommended for high-traction tracks, or when tires with additive are used.

Aluminum Backbone.

The main backbone of the car consists of high-precision, high-strenghth aluminum bulkheads and aluminum suspension holders mounted to the aluminum chassis.

All bulkhead parts are CNC-machined from premium Swiss 7075 T6 aluminum and have been designed to provide the lightest and strongest possible support framework for the car with maximum flex characteristics to increase the traction.

The bulkheads are anodized in a distinctive orange color. XRAY’s legendary attention to detail is noticeable in all the precisely chamfered edges.

Color may vary slightly between products.


The aluminum rear bulkheads have been completely redesigned to integrate with the flex adjustement system. The bulkheads extend forward under the 2-speed shaft with a 0.5mm space between the chassis and bulkheads.

Both front and rear bulkheads were redesigned to fit the anti roll bar composite bushing which extends the life of the bulkheads.

The clamps hold the rear shock tower as well as the graphite roll-center bridge. For an extra roll-center adjustment, the graphite roll-center bridge can be removed and the rear linkage mounted directly to the upper clamps to improve cornering speed and steering in very high-traction conditions.

The super-lightweight clamps have a very clean and lightweight design to create the lowest weight and CG, and still allow for easy access to the driveline for maintenance.

Rear Arm Mounts.

The rear arm mounts were redesigned to use the square composite bushings from the T4 and XB4 cars.

The outside position of the square insert places the rear arms at the same width as it was on the previous NT1s.

The inner position choices narrow the pin locations to help generate more rear traction and improve stability.

The narrow positions are recommended on low-medium traction tracks as it helps to improve rear traction and stability of the car on-power.

The wider positions are recommended to use on high tractions tracks as the car has better rotation and off power steering.

Upper Arm Holders.

Redesigned front upper arm holders not to touch front bulkheads, offering improved flex of the front suspension, and better forward traction.

Middle Shaft Holder.

The aluminum front middle shaft holder is inserted into the chassis for better centering.

The smart design allows easier access to the front belt and pulley for quick & easy front belt changes and maintenance.

The muffler mounting system is incorporated into the front middle shaft holder. This design helps to ensure that the muffler is mounted independently from the radio plate and chassis so there is no flex transfer. The extra-long muffler wire fits all standard mufflers.

2-Speed Bulkheads.

Rear layshaft bulkheads allow use of bracket bushings to connect the layshaft bulkheads to the rear bulkheads to reinforce the entire rear suspension. There are two flex settings of 2-speed bulkheads:

SOFT – Bracket bushings not installed. The car has more traction. Recommended for low-traction conditions.

STIFF – Bracket bushings are installed. The car is more free. Recommended for high-traction conditions.

Rear Graphite Stiffener.

The rear graphite stiffener – made from 2mm graphite material – was designed to enhance the flex characteristics around the engine area. The brace is mounted on the right side between the 2-speed bulkhead and the adjacent aluminum radio plate mount. The graphite stiffener provides optimized flex characteristics and can be easily removed when extra steering needed. An optional rear stiffener link is available to offer an in-between stiffness setting.

Radio Plate Mounts.

Radio plate mounts are made from Swiss 7075 T6 aluminum instead of composite material for improved flex characteristics. The mounts are located equidistant from the center centerline, as well as inline for more equal chassis flex characteristics.

Radio Plate.

A radio plate design allows mounting of the plate on the equidistant, aligned aluminum radio plate mounts for more equal chassis flex characteristics.

The front part of the radio plate was redesigned for improved in-corner steering, as well as improved flex of the front suspension for better forward traction.

Front Multi-Flex™ adjustment via the radio plate bushing in the servo saver area is a very useful feature. When the bushing is installed, the fixed setting is activated; when the bushing is removed, the screw is directly mounted on the servo saver post and the whole front suspension has increased flex. The fixed setting is recommended when there is sufficient in-corner steering. To increase the in-corner steering, the flex setting can be easily adjusted.

Fuel Tank Mounting.

The 75cc fuel tank with hypertonic tank lid and internal stone-type filter is positioned in the center of the car, and features a unique low-profile design to allow the fuel tank to sit as low as possible. The fuel tank is mounted with rummber grommets and O-ring with a special screw to reduce vibration. With extra space around the fuel tank in the radio plate, the fuel tank has greater movement in all directions which improves fuel pickup and scavenging as fuel is used up.

The fuel tank is molded from a special composite mixture which guarantees it to be extremely strong and robust. The fuel tank is glued together using a special self-developed robotic system that ensures maximum accuracy and precision in pre-heating and gluing.

The receiver battery pack is located beneath the fuel tank to help create a low CG. Using the optional micro-size receiver battery pack allows the fuel tank to be lowered by another 3mm, creating an ultra-low nitro touring platform.

Battery Holder.

The battery holder allows to fit the most common LiPo or LiFe batteries. The receiver battery pack can be easily removed from below the fuel tank by a quick access composite cover at the bottom of the chassis.

Optional graphite cover contains a special CNC-machined pocket in which to place the batteries, allowing the batteries to sit as low as possible. The main feature of the graphite cover is its integrated Multi-Flex Technology™ functionality to additionally reinforce the chassis in the vertical plane.

Radio Case.

Compact lightweight radio case features a clean design and layout. The radio case is attached to the side of the radio plate and will fit any standard-size receiver and optional switch with water-resistant rubber cover.

Roll-Center Bridge.

Graphite roll-center bridge made from thicker 4mm material removes unwanted flex of the rear suspension and improves cornering speed.

The roll-center bridge features six roll-center positions for the rear upper linkage (identical to previous versions).

Brake System.

The brake pads are made from the SLS material for smoother, more consistent braking.

Brake inputs are transferred precisely to the brakes by the ball-raced, super-smooth brake cam. The steel brake cam is machined from self-developed HUDY Spring Steel™ to ensure the longest possible lifespan, maximum strength, and lowest weight. Brake pad backing plates are made from laser-cut steel.

The laser-cut, precision flat-ground ventilated steel brake disk allows for true, wobble-free rotation.

Shock Towers.

Graphite rear shock tower is machined from thicker graphite 3.5 material for improved high-speed steering. Body posts are mounted wider on the shock tower for better stability.

Machined from premium grade 2.5mm (front) and 3.5mm (rear) graphite, the shock towers are small and lightweight. The well-proven shock mounting positions remain unchanged.

Shock Absorbers.

The shocks provide maximum traction and steering characteristics, and optimized up & down travel. Long shock bodies accommodate the long shock shafts, and pistons are made from special white Delrin™ material with optimized hole number and sizes.

Shock rods have been specifically hardened to ensure long life and maximum strength.

The set of pistons include 2 and 3-hole pistons with 1.0, 1.1, and 1.2mm diameter holes. The pistons are molded using special methods from Delrin™ material to ensure extreme roundness, while maintaining maximum stiffness and durability.

Shock bodies are CNC-machined from premium Swiss 7075 T6 aluminum and hardened to ensure maximum lifespan. External fine threading allows for quick & easy ride height adjustment. The shocks feature low-profile membranes for super-smooth, precise damping.

Shock Springs.

The NT1 comes equipped with C5.4 springs in the front to provide maximum stability and steering, and C4.0 springs in the rear to provide maximum traction and cornering speed.

The NT1 springs, like all other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.


With the intelligent design and construction of all drivetrain parts, the transmission is supersmooth and low-friction. From the small diffs, through the efficient ratios and lightweight pulleys, to the high-speed lightly-oiled bearings and lightweight drivetrain parts, all parts are designed for maximum efficiency and durability.

The rear drivetrain features dogbone drive shafts which help to generate more traction for the car. To accommodate the dogbone style drive shafts, the rear wheel axles were also updated.

Hardened with a proprietary process, the drive shafts provide unbeatable lifetime and reliability.

Gear Differential.

The diffs in the NT1 are small and light, ensuring lowest rotating mass and lowest CG. Rubber-sealed composite differential housings are molded from a special composite mixture that ensures non-expansion and non-deformation during operation and long runs, which would otherwise negatively influence the free movement of the gears inside. Differential gears are made from pressed steel, heat-treated and machined for ultra-precise and smooth operation.


All pulleys are molded from a special composite mixture to ensure low-friction operation, efficient and strong tooth profiles, and long lifespan.

PUR® Drive Belts.

The drivetrain includes PUR®-reinforced high-efficiency, low-friction drive belts to ensure that power is properly & efficiently transferred to all drivetrain parts.

2-speed Transmission.

The 2-speed transmission parts are installed on a precision-manufactured super-smooth middle layshaft made from tough HUDY shaft steel for 2-speed, which is additionally heat-treated for extra strength and long life. The 2-speed gear adapter is CNC-machined from Swiss 7075 T6 for precise fitting of the one-way bearing, and allowing super-precise and wobble-free installation of the spur gears. The high-quality German one-way bearing is hand-ground before installation for maximum running precision and strength. The 2-speed adapter is manufactured from hardened steel.

The spur gears are molded with a special technique allowing the gears to be absolutely true thus improving the drivetrain efficiency. Each gear is stamped with a tooth number for easy identification.

The intelligent engine mount design allows the setting & fixing of the engine position to ensure optimal gear mesh. Thanks to the specially-shaped gear teeth, the gears always have the same gear mesh which ensures that the engine can be set in position without the need for constant fine-tuning.

After initial gear mesh is set, the engine position is permanently set; the engine can be installed & re-installed repeatedly without the need to re-adjust the gear mesh.

Pinion Gears.

NT1 includes XRAY pinion gears machined from tough 7075 T6 alu and specially hardcoated for supreme strength, light weight, and high durability. Created on a special gear machine, all pinions feature ultra-precise tooth shaping and ultra-true running for vibration-free operation. Fine internal threading allows easy installation on XCA clutchbells (standard or lightweight versions). Each pinion is fine etched with the tooth number for easy & quick identification.

Engine Mounts.

Redesigned engine mounts offer improved and more equal chassis flex under the engine area.

Integrated Belt Tensioning.

Both front & rear upper clamps feature integrated belt-tension adjustment using adjustable bearing eccentric holders. All ball-bearings turn in composite hubs to reduce friction and improve drivetrain efficiency.

Integrated Suspension Settings™.

The NT1 features I.S.S. (Integrated Suspension Settings™) design. All adjustment possibilities are completely integrated, allowing complete set-up changes without changing or replacing any parts – no need for optional roll-center, anti-dive or anti-squat blocks. Using eccentric bushings anti-dive and anti-squat can be adjusted easily.

High-tensile steel suspension pivot pins are polished for smooth suspension action, and all pivot pins are captured to eliminate the need for E-clips.

Suspension Arms.

Front upper arms are made from softer material for improved in-corner steering and better forward traction.

The NT1 suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry of suspension points and materials used… these are all the concepts and details that had to be thoroughly reviewed to create optimal suspension arms.

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

Steering Blocks.

The tiny yet tough steering blocks are molded from a special composite mixture for maximum strength. Thanks to perfect molding, bearings fit into the steering block without any extra play to give maximum stability.

The steering blocks were designed for use with an aluminum Ackermann plate which allows greate Ackermann and bump-steer adjustment range. The aluminum Ackermann plate is mounted to the steering block and features 3 different Ackermann positions.

The plate is also mounted lower compared to previous steering block designs, which allows the steering linkage to be moved lower to gain more bumpsteer (giving increased steering response and improved in-corner steering). Bump steer can be easily changed by adding or removing shims.

The kit includes 0° kingpin steering blocks. Optional 1° kingpin steering blocks are available for more in-corner steering.

The steering blocks also accommodate the mounting of optional graphite Aero discs for improved steering.

Rear Uprights.

The compact rear uprights are small in size but are very strong due to the special composite mixture used. Thanks to perfect molding, bearings fit into the rear uprights without any extra play and therefore give maximum stability.

The rear uprights feature 2 positions for mounting the upper roll-center linkage, to allow changes to the roll-center position.

The rear uprights accommodate the mounting of optional graphite Aero discs for improved stability and traction.

Wheel Hubs.

Ultra-lightweight 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 alu hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting.

Optional offsets of -0.75mm and +0.75mm are available to adjust track-width.

Pivot Balls.

Front steel suspension pivot balls have a smaller diameter between the ball and thread to allow an increase in steering angle for increased cornering speed and out-of-corner steering.

The NT1 pivot ball suspension contains precision pivot balls which are specially hardened for enhanced lifespan and to withstand hard crashes. A total of eight (8) pivot balls are included, captured by strong M10 composite nuts to minimize weight and give smooth suspension movement.

Standard pivot balls are made from steel for maximum durability and lifespan. Optional lightweight aluminum or titanium pivot balls are also available.


To guarantee maximum reliability, all turnbuckles are manufactured from special HUDY Spring Steel™ material for turnbuckles for maximum core strength.

Front Wire Anti-roll Bar.
