Features

It has been rightfully called “miniature Formula 1” and has proven to be a class at the pinnacle of RC car racing. Fractions of a second separate the world’s best 1/12 pancar drivers. With simpler designs compared to larger touring cars, attention to detail is paramount, and XRAY is second to none in its evolution of a small, agile, and super-fast car that is destined for the Winners Circle.

To the untrained eye, the new XRAY X12 may at first glance seem a simple and traditional design, but it’s upon closer inspect that the details and engineering marvels shine through. With unparalleled experience and innovation in its team, XRAY has achieved a state of pancar perfection with the X12 by focusing on strategically-planned refinements to create a car that is easy to drive, work on, and adjust.

Direct feedback from factory team drivers, as well as customers from around the world, allowed the XRAY factory to turn a concept into reality… this is what we do best at XRAY.

Designed in virtual reality using the world’s most sophisticated CAD tools, and manufactured using the world’s best machining and molding machinery, the X12 achieves a level of premium perfection in all details that is second to none. All parts are purpose-designed and manufactured by XRAY, so all parts fit and work perfectly together.

In a world where overly-complicated designs hinder rather than enhance, the X12 stands alone and ahead as the best performing out-of-the-box racer.

See it. Feel it. Drive it.

XRAY X12 Platform.

Legendary XRAY premium design, workmanship & material quality and unmatched attention to the finest details result in a state of perfection achieved by well thought-out refinements to create a car that is easy to drive, work on, and adjust. From unique HUDY Spring Steel™, through the world’s strongest Swiss 7075 T6 aluminum, along with XRAY’s own secret composite mixtures, to the premium high grade graphite materials… everything is exclusive and premium on the X12. Using premium European exclusive materials crafted by XRAY’s engineering artists using the state of the art German, Italian, and Swiss CNC machines, the X12 is a blend of only the world’s finest.

Chassis.

The new chassis is 3mm narrower compared to the previous chassis to centralize all the weight to the centerline even more. The cutouts under the front suspension are smaller to stiffen the flex, optimize steering characteristics, and make the care easier to drive.

The new chassis allows for changing the center shock position to either forward or rearward position. It also includes holes for composite battery backstops to eliminate battery movement when inline battery alignment is used.

Pod Plate.

The pod plate is 3mm narrower to allow the composite rear pod links to be repositioned more towards the center to improve steering response and side-to-side weight transition.

Center Shock Position Adjustment.

An innovative new feature is the possibility to change the center shock position. By moving the center shock mounts on the chassis to either the forward or rearward position, the dampening and steering characteristics of the car can be changed. The forward shock position allows the car to drive better over bumps and improves on-power traction, while the rearward shock position improves steering response and the car changes direction quicker.

Micro Shock Absorber.

XRAY micro shock has a scaled-down design from its “big brother” counterpart in XRAY’s successful touring car platform. The fully-adjustable shock features an aluminum shock body that is hard-anodized for ultra durability. The fine-threaded shock body allows for quick and easy shock spring preload adjustment. Tiny, thin shock membrane gives smooth dampening characteristics, and a super-soft silicone shock O-ring gives super-smooth operation while preventing oil leakage. The ultra-finely finished shock shaft with precise-molded composite shock piston ensures optimum shock oil flow and smooth shock absorber action. A simple yet smart shock construction allows for quick and easy shock-length adjustment for rear pod downstop adjustment.
The number of holes in shock piston were changed from 2 to 1 for improved on-power steering

Shock Adaptor.

The shock adaptor allows for quick & easy changes to the shock position. Using the adaptor allows for the new forward shock mounting position, and when the adaptor is removed the standard rearward position is used.

Steering Block.

Excess play in the steering block was removed to improve steering response.

Bump Steer Shims.

3mm shims are included for the steering block to make the car easier to drive under high-traction conditions.

Upper Arm Position Adjustment Shims.

The new upper arm shims allow for moving the front upper arm mount together with the upper arm more out from the lower arm, thus generating less camber gain and making the car easier to drive. With more shims, less camber gain is generated, reducing initial steering and giving less “twitchiness.”

Composite Upper & Lower Pivot Brace.

The composite upper & lower pivot brace were redesigned to allow the pivot ball be to lowered by 0.5mm so as to lower the roll center of the car. Lower roll center provides more rear traction and stabilizes the rear of the car.

Pod Pivot Ball.

The pivot ball is smaller to save the weight, which is very important in 1/12 class. The pivot ball has an internal thread so the locking nut mounted on the top is not used any more. This saves weight but also allows for greater side movement of the whole rear pod.

Rear Link Pod Upper Plate.

Rear link pod upper plate includes a hole so the optional side shock can be mounted. The advantage of using the side shock is that it provides more traction in low-to-medium traction conditions.

Rear Link Brace.

The rear link brace was redesigned to allow the battery to be moved 4mm more rearward when the cross-chassis alignment battery configuration is used. By moving the battery more rearward, the car has more steering.

Composite Battery Backstops.

Included composite battery backstops eliminate battery movement when the inline alignment battery configuration is used.

XRAY Orange Color.

The majority of aluminum parts are orange anodized for better, more distinctive XRAY design look. The combination of the traditional XRAY’s orange and black color gives the car the perfect look.

Weight Balance.

As part of the chassis design, weight balance was thoroughly redesigned and improved on the X12 platform. The battery placement was moved to the left side for improved side-to-side weight balance and to reduce rear pod binding caused by motor wires. With the new chassis layout the electronics wiring access was improved.

Battery Placement.

The position of the battery placement in the chassis has a significant influence on weight balance adjustment. To offer instant and comfortable weight balance adjustment – depending on various track conditions – the battery placement can be quickly changed from inline to cross-chassis. Smart and handy - an all-new unique feature and system.

Centralized Shock Mount.

The new front center shock mount was completely redesigned for the X12 platform. The entire platform was moved from the side to the absolute center of the chassis. The rigid centrally-mounted shock mount prevents tweak and significantly improves side-to-side stability.

Track-Width Adjustment.

The front suspension on the X12 platform has been completely redesigned and improved. The new lower suspension arms feature smart eccentric aluminum inserts which allow quick & easy changing and setting up of track-width depending on track conditions. Optional aluminum 0.5mm and 1.0mm eccentrics are used to set the track-width either narrower or wider.

Straight side springs.

Straight side springs have more consistent and smoother compression for smoother out-ofcorner exiting, and reduction of traction rolling.

Ride Height Shims.

The front suspension uses ride height adjustment shims which enable very quick, precise and hassle-free ride height adjustment for various track conditions. The set of 0.2, 0.4 and 0.6mm ride height adjustment shims are included for fine tuning.

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.

Front Suspension.

Strong, simple, yet refined front suspension made from strong, lightweight, self-developed composite material. Reactive caster settings available using 2.5°, 5.0° or 7.5° eccentric bushings. Tiny yet strong HUDY Spring Steel™ upper pivot balls ensure smooth, bind-free operation, while composite lower pivot balls allow the front suspension to operate even more smoothly. Fast & easy adjustment of front caster, track-width, roll center and ride height via included shims and clips.

Reactive Caster.

Reactive caster is easily adjustable by using easy-to-change eccentric bushings of 2.5°, 5.0° or 7.5° (included). Reactive caster is used to adjust the amount of caster change when the front end of the car is compressing (diving) or decompressing (rising).

Steering.

Chassis features pre-drilled holes for the servo mounts on both left and right side which allows the placement of the servo to balance the car as necessary. Aluminum servo stands allow flat mounting of the servo to the chassis to keep lowest possible CG.

Kingpins.

Super-smooth, hardened steel kingpins provide
the foundation for the front suspension.

Adjustable Ackermann.

The quick adjustable Ackermann positions can be adjusted by adding/removing shims between the servo and servo mounting posts. The composite shims included in the kit come in three different sizes: 3x6x1, 3x6x2, 3x6x3. Ackermann influences the steering of the car, and therefore it is important to make it an adjustable feature.

Servo Saver.

Tiny yet robust servo saver protects the servo from impact damage. Easy Ackermann adjustment is made via shims mounted below steering block pivot balls.

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.

Alu Bulkheads.

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.

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.

Motor Access.

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

Rear Axle.

The ultra-strong, lightweight steel axle provides maximum reliability even in serious crashes. The rear differential features high-grade precision carbide balls for spur gear, hardened and precision-ground D-steel shims, and premium carbide axial thrust-bearing.

Spur Gear.

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

Side Tubes.

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

Adjustable Turnbuckles.

Front upper 3mm adjustable HUDY Spring Steel™ camber turnbuckles are lightweight yet can withstand hard impacts, with precision threading to ensure fine camber adjustment. Steering linkages are made from adjustable 4mm turnbuckles manufactured from lightweight aluminum.

Pivot Balls.

High-precision, HUDY Spring Steel™ upper pivot balls and composite lower pivot balls ensure smooth & precise movement of the front suspension.

Wheel Axles.

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

Alu Rear 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.

Antenna Mount.

A tiny lightweight antenna mount secures the lightweight yet strong molded fibreglass rollover antenna.

Front Chassis Protection.
