The GTXE is typical XRAY – premium, professional, high-competition RC car for the most demanding racers, developed with attention to detail and backed by premium service & support…a luxury masterpiece.
With XRAY's uncompromising design philosophy bringing everything together to make the best GT electric car, the GTXE has the unique XRAY character, born of precision craftsmanship, highest attention to detail, and using only the finest quality materials.
The GTXE’22 features a longer chassis plate that is the backbone of the electric focused concept.
The chassis length is increased to stretch the wheelbase, combined with the wider rear section, resulting in improved stability.
The updated layout also includes provisions to install the new rear diffusor and mount the front and rear suspension holders directly to the chassis plate.
The chassis features a new locking system for the servo saver posts to ensure the components will stay secure during chassis flex in extreme conditions.
The chassis is CNC-machined from 3mm high-quality Swiss 7075 T6 aluminum; strategically machined in low-stress areas and then anodized to make it as light as possible without affecting strength or rigidity.
The new E-concept layout uses a forward motor position and saddle pack batteries. The motor is placed in front of the center differential, opposite the steering servo, with split, saddle pack batteries in the rear. The split packs lay flat in the holders, reducing the CG compared to taller brick pack layouts. The motor has better cooling in the front location, and the split batteries also maintain lower temperatures during each run.
The new saddle pack layout features tweak-free split battery holders to secure the packs. These battery holders will fit both standard and ‘shorty’ packs, with the shorty packs allowing additional weight balance control by shifting them front/back in the holders.
In addition to the new battery and motor positions, the GTXE’22 includes a molded electronics plate that is positioned next to the steering servo. The ESC, receiver and transponder are all installed on this plate for easy removal and maintenance.
To fit the revised electronics layout there is a new graphite servo holder plate. The servo horn position is moved further forward and uses a shortened link to connect to the steering system.
A smaller gear adapter works with 45T, 46T, and 47T spur gears, offering an expanded range of ratios to match the gearing requirements for maximum motor performance.
All-new diffusor used at the rear of the car helps to increase downforce that improves stability and makes the GTXE’22 easier to control at high speeds.
To improve the consistency of the differential performance throughout each run, the gear box covers are milled out for air flow to help reduce diff temperatures. This prevents overheating the diff oils and ensures more consistent handling during long mains and extends intervals between rebuilds. The rear gearbox and cover both have additional material milled out to increase airflow and cooling for the rear diff.
The front upper bumper brace was also modified with a milled opening to allow more air into the front gear box.
All-new front and rear suspension holders are separated from the bulkheads and installed on the chassis. Mounting the holders directly to the chassis plate eliminates any flex from the bulkheads, improving the precision and responsiveness of the GTXE’22.
The front kick-up angle was reduced, helping to create more steering and reduce tire wear.
The rear holders still offer multiple anti-squat positions, but the new plates have less anti-squat, which is better suited for the GT category to increase the stability of the car.
The new aluminum suspension holders continue to feature the Integrated Suspension Settings™ (I.S.S.) that allows for quick & easy suspension geometry changes
Using the eccentric suspension bushings inserted into aluminum suspension holders, and a few suspension shims, the GTXE suspension geometry can be completely adjusted in seconds.
Mounting the suspension holders directly to the chassis plate means the gearboxes can be lifted to improve the driveline geometry for the GTXE’22. Aluminum gearbox spacers raise the differential height and improve the driveshaft angles, creating more traction on corner exit while improving mid corner rotation. The new driveshaft positioning also help to extend the service intervals of the driveshafts’ cv joints and the diff outdrives.
Bulkheads allow super fast and ultra comfortable diff exchange and servicing by dismounting only 6 screws from the front of the bulkhead and from the bottom of the chassis. This super fast diff access is available both in the front and rear.
The updated lower bumper brace is modified for additional clearance around the new front suspension holder.
New front C-hubs were specially developed for the GT on-road platform. After extensive tests of various caster angles, the final 6° caster block was selected as the best choice to work in the wide range of racing conditions found at GT events.
The new C-hub geometry significantly improves steering characteristics over the previous 16° hubs. The reduced caster angle also helps to reduce tire wear, creating more consistent handling during longer main events.
The steering blocks feature new steering Ackermann plates that improve corner entry steering by increasing the outside wheel angle. Machined from graphite, the plates are easy to mount to the steering blocks for replacement or adjustment.
The rear uprights are now moulded from a harder material that reduces flex in hotter conditions and makes the car more stable in the corners.
The uprights feature all-new graphite extensions that move the camber link mount higher and further inboard to shorten the rear camber link. The graphite extensions feature 5 different roll center positions for more tuning options on the GTXE’22.
The rear uprights use the larger 8x16x5mm outer ball-bearings for increased reliability and lifespan. The smart design allows the same upright to be used on both left & right sides, reducing the number of spares needed in your parts box. The wheelbase position is adjustable using 2 shims along the lower suspension pin.
The rear uprights feature integrated geometry adjustments including camber, upper and lower roll center and wheelbase.
Both front and rear suspension arms are now softer than the previous GTXE kits. In comparison to the extra-hard suspension arms included in previous GTXE kits, the new GTXE’22 features Medium front and Hard rear suspension arms. This combination of softer arms helps to increase traction in every track conditions.
All-new aluminum suspension arm extensions create completely new shock geometry specific for the needs of the GT category. The shock extensions increase stability and improve the corner speed.
Both front and rear shock towers feature updated geometry with different shock mount and camber link positions on a tower that is lower overall compared to previous versions.
The new shock mount locations were repositioned in relation to the location of the lower shock mount extensions on the suspension arms, resulting in improved corner speed.
The new front roll center positions help create more steering and the revised rear roll center positions free up the rear end of the car and helps with stability on power.
The shorter front and rear upper camber links match the rear hub graphite camber extensions and front and rear inner camber link positions to make the car more reactive in front and provide more rotation from the rear suspension.
The all-new front and rear shock springs were specially developed for GT on-road racing.
There are two new spring choices – both softer that original GTXE springs, and both featuring a progressive spring rate. For the initial setting the stiffer of the two new springs are used in front with the softer springs in rear. In this configuration the GTXE will have maximum traction in most track conditions.
XRAY shock springs are manually measured, selected, and matched into pairs to guarantee precisely equal length and damping characteristics.
A longer front composite brace makes the car more precise and easier to drive. The brace is now mounted with two screws to the chassis for additional strength.
The longer rear brace is moulded from a medium-stiff composite mixture for proper flex control and allows the installation of optional graphite inserts to reinforce the brace to make it even stiffer (suitable for high-traction conditions).
The servo saver features a new conical spring that is longer and stronger. The new spring ensures more precise steering and improved reliability.
The servo saver posts feature a new locking system that keys into the chassis plate to ensure the servo saver setting will not change while running.
To improve servo saver reliability (especially in dusty conditions), it is moulded from graphite material that is more resistant and efficient in dusty conditions. The dual-arm steering system is simple yet effective, featuring an integrated easily adjustable servo saver, and a Swiss 7075 T6 aluminum steering plate.
Ackermann is easily adjusted by changing steering link mounting positions on the steering plate. Bump steer is adjusted by inserting shims between the steering plate and steering linkage.
The new top deck features additional clearance so the servo saver will not bind when overtightened and will always work freely. Fits both GTX and GTXE.
Central dogbone driveshafts are lighter than CVD drive shafts for improved acceleration. They can also have a longer lifespan thanks to the easier maintenance of the dog bone and outdrives, reducing servicing requirements.
All the drive shaft parts are machined from Hudy Spring Steel and are specially hardened.
To work with the new shock geometry, the front and rear anti-roll bars included in the kit are softer than previous versions.
The GTX anti-roll bars help control chassis roll, increase corner speed and improve the stability of the car.
The front & rear roll bars are easily mounted to the bulkheads and can be adjusted using the connected linkages.
Manufactured from spring steel material, anti-roll bars of different thickness are available for fine-tuning.
Designed in virtual reality using the world's most sophisticated CAD tools and manufactured using the world's best machining and molding technology, the GTXE is second to none amongst GT electric cars. All parts are purpose-designed and manufactured by XRAY, so everything fits and works perfectly together.
I designed and hand-made my first off-road cars back in 1986, and they were dominating the races thanks to unbeatable reliability and superior performance. Years later in 2004 we debuted our first mass production XRAY XB8 platform based on our long-term experiences, knowledge, and R&D expertise gained over decades, taking over the heritage I brought with me.
Using the XB8E and GTX8 platforms, we worked with the XRAY R&D team to create the finest, highest-performing GT electric car. I am happy that we carried forward the legacy of my first off-road car into this new platform… one that can take you to the Winners Circle.
Dipl. Eng. Juraj Hudy
XRAY Chief Designer
The GTXE project follows a typical development progress at XRAY: 3D models were first printed & tested, and after successful test results the production moulds were machined. To ensure perfect fitment of all parts, all pieces are individually tested during the development phase and then are tested on track to ensure maximum reliability and performance.
Before I started racing off-road cars, I was actively professionally racing 1/5 scale on-road cars and I won 2x a European Championship. In my position as R&D Designer at XRAY, I was very happy to be involved again with an on-road project where I could bring my prior experience to the table.
I have thoroughly enjoyed my involvement in this new GT project, and I strongly believe this class will rapidly gain popularity due to its simplicity, easy handling, and great fun. I will continue to support the ongoing development of this new platform, and will be available to support all XRAY customers.

The differentials feature larger capacity cases and larger internal gears with more teeth for improved differential moment. The larger oil volume and the shape of the gear teeth reduce overheating. The diff pins have stronger design to improve reliability.
Super-lightweight diff outdrives are machined from HUDY Spring Steel™ with unnecessary material removed from the outer part of the outdrives to reduce rotating weight without affecting durability. The inner portions of the outdrives are additionally hand-ground for maximum precision and fitment into the diff case.
The outdrives are hardened using HUDY’s own special hardening process to provide extended lifespan and reliability.
Differential main gears are manufactured from HUDY Gear Steel on a precision manual gear machine. The material was specially formulated and developed for use in gears. All gears are hardened to provide the longest possible lifespan.
To improve drive train efficiency, the 13T pinion gears are now included for both front and rear bulkheads. Thanks to the higher 3.54:1 internal ratio, vehicle acceleration has also been improved.
The motor is connected to a mounting plate, with the assembly then inserted into an integrated motor holder/drivetrain support. The design of this system allows quick & easy motor rotation to adjust gear mesh, and then clamping into position to prevent further movement.
The motor mount is machined from Swiss 7075 T6 and is 2mm wider for improved durability.
Longer front & rear shock shafts are now +3mm longer for increased set-up possibilities and to allow more suspension travel.
The shock caps feature 4 bleed holes for easier building and more precise rebound control. Multiple shock membrane choices are available to tune the suspension to a wide variety of track conditions.
Oversized big-bore shocks featuring 16.2mm I.D. shock bodies are externally threaded with an adjustable collar for quick & easy spring preload adjustment. The shock bodies are hardcoated in a titanium color and feature a 1-piece alu shock cap.
Ultra-precise shock pistons feature 6-, 8- and 10-hole options. The big-bore pistons are molded from tough, well-proven Delrin® material for smooth action and durability. The precision molding production process ensures perfect piston roundness after production, so that the pistons move super-smoothly inside the shock bodies for identical, perfect action in all shocks.
To guarantee maximum reliability, all turnbuckles are manufactured from a special blend of HUDY Spring Steel™ which is specifically formulated for turnbuckles. The turnbuckles have a tougher core and are well suited for steering system and rear upright linkages.
The compact front bumper is made from high-resilience foam. The front upper bumper holder and lower composite bumper are molded from rigid composite to withstand hard crashes.
Ultra-lightweight 17mm wheel hex drive hubs are CNC-machined from Swiss 7075 T6 black-coated aluminum. GTX includes +2mm off-set both front and rear.
The alu hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting.
The drivetrain ball-bearings are greased instead of oiled to maximize the lifespan of the ball-bearings, especially in dusty conditions. For increased reliability, the front and rear transmission ball-bearings as well the 2-speed ball-bearings feature metal shields.
XRAY’s self-designed GTX body – made from high-quality Lexan™ material – features high-downforce areas: front windscreen for proper airflow, side downforce areas for higher stability. The high-performance, low-profile aerodynamic body was designed by XRAY to perfectly fit the GTX and GTXE. The rear part of the body includes 3 wing struts for added durability; a high-strength wing is included.
