Dipl. Eng. Juraj Hudy
XRAY Chief Designer
With countless wins in multiple classes at local, regional, national, and international levels, XRAY has become the standard by which all other racing cars are measured. The XT2 brings a new level to the high-competition world of stadium truck racing.
Some information shown below may include details from previous kits, and it may vary slightly from current kit specifications.
CNC-machined from high-quality 2mm Swiss 7075 T6 aluminum, the chassis is lightweight without affecting strength or rigidity, and is 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.
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.
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.
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.
To improve front chassis flex, the front composite chassis braces were redesigned and shortened to allow for mounting all-new graphite side guard braces for better stability and performance.
The upper brace is also part of the Multi-Flex™ system which allows flex adjustment of the front of the car for particular track conditions.
To increase the reliability of the steering system, the universal ball features a backstop that ensures that the linkages will not disconnect in a crash.
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. Ackermann is easily adjusted by quickly & easily changing the steering link mounting positions on the steering plate. Further Ackermann adjustments may be made by inserting shims on the steering plate and changing various graphite extension plates on the steering blocks.
Bump steer is easily adjusted for more aggression by inserting a shim between the steering block and steering linkage.
To improve the precision of the shock shaft movement, the lower composite shim was redesigned and updated with a more accurate and precise mould design.
The shocks are membrane-free, yet they still allow for easy, consistent building and rebound setting using the bleed-screw shock cap design.
The aluminum body and lower cap are machined from premium Swiss 7075 T6 aluminum.
Shock rods are machined from special steel material, precision hand-ground for maximum smooth operation, and additionally hardened for improved lifespan.
Shock pistons are made from Delrin® and are molded using ultra-high precision moulds. All-new 2-hole pistons (1.6mm and 1.7mm holes) are now included in the set.
The XT2 springs have been specifically designed to complement the shocks.
The XT2 springs, like all other XRAY springs, are manually measured, selected, and matched into pairs to guarantee precisely equal length and damping characteristics.
There are two types of springs offered:
As a part of the Multi-Flex™ system, the front upper deck is used to adjust chassis flex.
There are two different upper decks available – medium (optional) and hard (included), each suitable for particular track conditions.
An optional medium-hardness composite upper deck is great for low-and medium-traction conditions.
The included brace is moulded from hard-hardness composite and is suitable for high-traction and very-high traction conditions.
Access to the rear differential is super easy. By simply 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.
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
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, 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.
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.
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.
There are two different caster blocks available: medium (optional) and hard (included), each suitable for particular track conditions.
Outer suspension pins holding the front caster block and rear uprights feature wheelbase shims for quick & easy wheelbase and weight balance adjustment. 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; recommended for medium- and high-traction conditions. By moving the arms to the rear, the balance & weight of the car transfer moreforward.
For maximum reliability, all turnbuckles feature a tougher core from special HUDY Spring Steel™ material. These turnbuckles are used for front & rear upright linkages and steering system.
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.
Battery strap allows easy access to the battery.
Roll center holders allow easy roll center adjustment.
The XT2 includes a motor plate for the front gearbox configuration.
Composite shock towers for front motor configuration are included in each XT2C.
Beefy 6mm thick body posts are made from special composite material that provides maximum strength but sufficient flex to reduce body post breakage in hard crashes or if the car flips over. The body supports are rounded to have a better fit and provide better support to the car body.
For ultimate tuning and adjustment, XRAY offers optional body height adjustable body posts for independent front & rear body height adjustment by +1mm or +2mm.
Anti-roll bars used to stabilize the car are manufactured from spring steel material. The included front anti-roll bar is mounted to the front body mount and can be easily adjusted via linkages.
In specific track conditions when the rear of the car must be stabilized, an optional anti-roll bar (#362400) can be easily installed. The anti-roll bar is mounted to the rear roll center holder and can be adjusted via the included linkages.
Anti-roll bar wires of different thicknesses are optionally available for fine-tuning; the wire thickness is laser-engraved for easy identification.
The extensive range of adjustment possibilities include: caster, camber, toe, kick-up, anti-squat, ride height, downstops, track-width, lower roll center, upper roll center, roll center position, bump steer, wheelbase, Ackermann, adjustable shocks, adjustable rear diff, adjustable slipper clutch, and adjustable XRAY Multi-Flex™.
Chassis design focuses on balanced weight distribution and weight transfer. The chassis features pre-drilled holes for additional balance weights. Centerline holes are pre-drilled for easy balancing with the HUDY Chassis Balancing Tool #107880.
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 are 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 for your car are exactly same as those used by the factory racing team, thus ensuring very exacting set-ups and handling.
