The racing team travels to all major races around the world to provide XRAY drivers with 1st -class support and service so they can be assured that they always get 1st class treatment as part of the XRAY team.

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 legendary attention to detail by our artistic production specialists. The XT2 is truly a masterpiece.

Chassis.

CNC-machined from high-quality 2mm Swiss 7075 T6 aluminum, the chassis is lightweight without affecting strength or rigidity, and is additionally black coated at XRAY’s own in-house fully robotic coating line.

Weight distribution, chassis width & length, and proper flex have all been incorporated into the design of the chassis.

Multi-Flex™.

The invention of XRAY Multi-Flex Technology™ has resulted in some of the most significant milestones in RC model car development in the last decade. This innovation has not only resulted in awards and accolades, but has proven to be a distinct competitive advantage at tracks worldwide to help XRAY cars dominate races at local and national levels.

The XT2 incorporates Multi-Flex™ adjustment technology, which allows tuning the chassis flex for different track conditions.

Regardless if the track has low, medium, or super-high traction, you can adjust the chassis flex to suit track conditions to gain a distinctive advantage.

Electronics Layout.

The electronic layout allows for moving the batteries frontwards/rearwards, as well as using standard or mid-size servos and either using short pack or saddle pack batteries.

Side Guards.

Side guards are an integral part of the XT2 Multi-Flex™ system. Moulded from medium-hardness composite material, the side guards make the chassis frame flex suitable for the majority of track conditions.

There are two different chassis braces available – medium (included) and hard (optional) – which are suitable for particular track conditions.

The included side guards are moulded from medium-hardness composite and make the car faster in corners.

An optional hard-hardness composite moulded braces give the car increased stability on jumps.

Chassis Brace.

The front lower chassis brace is another component of the Multi-Flex™ system that influences flex and handling. There are two different chassis braces available – medium (optional) and hard (included), each suitable for particular track conditions. The brace is mounted directly to the chassis to hold the entire front assembly and front suspension, including the front protection bumper.

An optional medium-hardness composite molded brace is suitable for low- and medium-traction tracks.

The included brace is moulded from hard-hardness composite and is suitable for high- and very-high-traction tracks.

Upper Deck.

As a part of the Multi-Flex™ system, the front upper deck is used to adjust chassis flex. XT2 includes two different upper decks – medium and hard one, each suitable for particular track conditions.

The medium-hardness upper deck is great for low-and medium-traction conditions.

For high-traction and very-high traction conditions the hard upper deck can be used.

Gear Box.

The XT2 gear box is designed with all the finest details and craftsmanship incorporated. All parts fit perfectly together, and the super-easy access to the rear differential will be appreciated by every racer. The durable gear box houses the differential with all the rear transmission, and allows the mounting of the rear roll center holder, motor plate, and rear shock tower.

Gear Box Gears.

There are two different gears configurations.

  • 3 gears configuration – increases stability, provides higher corner speed and more effective braking but has less chassis roll.
  • 4 gears configuration – increases traction and has increased chasiss roll but brakes less.

Easy Diff Access.

Access to the rear differential is super easy. By just releasing a few screws on the rear cover of the gear box, the differential can be easily taken out and inserted back inside without the need for further disassembly. Smart engineering.

Drivetrain.

The XT2 is a conventional gear-driven 2WD off-road car featuring:

  • Rear gear differential with adjustable oil viscosity, featuring 53T gear and internal satellite gears
  • 36T graphite composite idler gear
  • 20T super-lightweight Swiss 7075 T6 hardcoated aluminum top shaft
  • adjustable slipper clutch with 81T main spur gear
  • rear CVD drive shafts

Gear Differential.

Slipper Clutch.

Power from the motor is transferred to the drivetrain via an externally-adjustable central slipper clutch for quick & easy tuning. The 3-pad slipper clutch ensures super-smooth clutch operation and efficient and consistent braking. It is very easy to make ultra-fine adjustments to the clutch externally.

The slipper clutch pads are made from ultra-efficient SLS material with very high slip efficiency, thus allowing very precise slip adjustment.

The lightweight slipper plates are machined from premium Swiss 7075 T6 and additionally hardened before a final black surface treatment. The plates have a machined relief which decreases the friction surface to assist with clutch slip adjustment. With this plate design, pressure is focused on the circumference of the clutch pads for increased efficiency.

Spur Gear.

Precision-molded spur gears are made from XRAY’s exclusive secret blend of composite material, allowing the gear to run true yet be robust enough to handle high-performance brushless motors. The spur gears are designed to have the lowest possible weight while staying strong and light. Each gear is stamped with the tooth number for easy identification.

The XT2 is equipped with an 81T spur gear which suits the majority of tracks. For additional tuning, optional 75T, 78T, 84T and 87T spur gears are available.

Drive Shafts.

XT2 constant velocity drives (CVDs) are manufactured from world-renowned HUDY Spring Steel™. The drive shafts are some of the world‘s thinnest yet most durable drive shafts used in electric off-road cars.

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

Motor Plate.

The black-coated Swiss 7075 T6 aluminum motor plate holds the slipper clutch assembly as well as the gear box, and features an adjustable motor plate position. To reinforce the assembly, the motor plate is connected via a motor plate brace to the upper brace mounts.

Battery Strap.

Changing batteries is quick & easy with the included battery strap with aluminum nuts. The battery pack can be installed either frontwards or rearwards, and the included foam spacer helps to ensure the battery pack will not fall out. The chassis layout allows the use of either short packs or saddle-pack batteries.

There are two different battery straps available – composite (included) and adjustable graphite (optional), each suitable for particular track conditions.

The included composite battery is suitable for low-, medium- and high-traction tracks.
An optional adjustable graphite battery strap is suitable for very-high traction tracks and suggested especially for carpet racing.

Suspension.

Correct suspension geometry is one of the most important features of any RC model car, while at the same time being one of the most difficult & challenging features for a designer.

Suspension is always a mixture of:

  • design and shape of individual suspension parts
  • flex and hardness
  • materials used
  • mounting system
  • geometry and position of mounting points of connecting parts

From the suspension arms, through the suspension blocks, to the light yet robust steering blocks, every suspension part has been carefully designed for the 1/10 off-road racing platform to provide responsive racing characteristics in all conditions.

I.S.S.™ Suspension Holders.

The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.™) which allows for quick & easy suspension geometry set-up.

Using eccentric suspension bushings – which are inserted into Swiss 7075 T6 aluminum suspension blocks – as well as additional shims and turnbuckles, the XT2 suspension geometry can be completely adjusted:

  • camber
  • toe-in
  • rear roll-center
  • anti-squat
  • track-width
  • Suspension Arms.

XT2 suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry, and materials used… these are all part of the concepts and details that are thoroughly reviewed to create optimum suspension arms.

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

There are three different suspension arms available: medium (optional), hard (included), and graphite (optional), each suitable for particular track conditions.

Caster Blocks.

The caster blocks are very lightweight, yet their construction makes them very stiff & rigid. Caster can be adjusted with values 0°, 2.5°, or 5° using included caster bushings.

Using included shims in rear and in front, both front and rear blocks can be moved forward or rearward to adjust weight balance depending on track condition.

By moving the arms to the front, the balance & weight of the car are transferred more to the rear; this is recommended for medium- and high-traction conditions. By moving the arms to the rear, the balance & weight of the car are transferred more to the front.

Hex Hubs.

Ultra-lightweight 12mm 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 rear alu hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting.

To adjust track-width, optional offset wheel hex drive hubs are available.

Steering System.

The dual-arm steering system is very simple yet effective. The steering system is fully bearing-equipped with 8 high-speed ball-bearings for very precise steering. The Ackermann is easily adjusted by quickly & easily changing the steering link mounting positions on the steering plate.

Bump steer is easily adjusted for more aggression by inserting a shim between the steering block and steering linkage.

Ackermann is also easily adjusted by inserting a shim on the steering plate as well changing various graphite extension plates on the steering blocks.

Turnbuckles.

For maximum reliability, all turnbuckles are manufactured from special HUDY Spring Steel™ material for turnbuckles which features a tougher core. These turnbuckles are used for front & rear upright linkages and steering system.

Front Lower Arm Mount.

The lower composite arm mount is an important part of the chassis where the lower arms mount, and the block has an integrated 26° kick-up angle. Optional aluminum and brass arm mounts are available for further weight balance adjustment.

Shock Towers.

Composite Front and rear shock towers include multiple shock positions, and the rear shock tower also holds the wing mount.

Shocks.

Well-built, reliable shock absorbers are extremely important for super-smooth suspension action on any type of track. The shocks on the XT2 have been specifically designed to be built easily, perform consistently, and last reliably. Careful attention was paid to the smallest details during the design process, as well as during long-term testing in various conditions.

The shocks are membrane-free, yet they still allow for easy, consistent building and rebound setting using the bleed-screw shock cap design.

Downstop is adjusted using composite shims under the pistons. Upstop travel is adjusted using composite shims under the shock collar.

The aluminum body, lower nut, and bleeder shock caps are all machined from premium Swiss 7075 T6.

Shock rods are machined from special steel material, precision hand-ground for maximum smooth operation, and additionally hardened for improved lifespan.
