Racing Pedigree

The mandate of the XRAY Development Team is to pursue perfection and innovation, while constant developing and redefining the “performance envelope.” Through ongoing development and improvement with the XB8 nitro platform, the 808E was borne.

With a “no compromise” vision and strategy in mind, the electric buggy 808E platform was conceived.

Balanced load distribution creates outstanding driving dynamics and excellent track stability, making the 808E super-easy to drive in any racing condition – no matter if you drive on flat fast track, bumpy technical track, or sky-high jumps – the 808E is the new form and level of performance.

Loaded and equipped with premium high-tech materials and engineering throughout – excellent and proven suspension and geometry; oversized shocks; optimal and centralized weight balance; superior drivetrain concept – the 808E is easy to drive and control, making it a top performer under all racing conditions. Precision controllability at your disposal… response so fast and precise that you think your mind is directly connected to the car. Squeeze the throttle for the first time and you will immediately experience what the car’s looks only hint at.


The proven XB808 nitro chassis design has been completely redesigned for the electric 808E and its different load characteristics. Optimal weight distribution and centerline placement of internal parts for improved side-to-side weight balance.

The chassis is CNC-machined from high-quality Swiss 7075 T6 hard-anodized aluminum, and is strategically machined in low-stress areas to make it as light as possible without affecting strength or rigidity. The chassis is hard anodized at XRAY’s own in-house fully robotic hardcoating line, ensuring a perfect hardcoated surface.

Non-essential material was removed to allow for the lightest weight and lowest possible center of gravity.

All screw holes on the bottom of the chassis are countersunk, allowing for a very smooth chassis underside with no protruding screw heads.

Strong composite side guards help protect the internal components.

Well-proven Superior Suspension

Well-proven suspension components from the nitro XB808 are carried over to the electric-powered 808E, so it benefits from years of development from XRAY R&D.The suspension geometry was fine tuned to give the 808E super-easy handling in all racing conditions.

Suspension Arms

Suspension arms are one of the most important parts of any RC model car, as they directly influence the handling and racing characteristics of the car. The 808E suspension arms carried over from the XB808 nitro buggy and optimized for the new car. 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 the optimum suspension arms.

Based on excessive knowledge gained from the previous XB8 cars, several different suspension arm designs were tested in both virtual reality and in-car to find the final best design. 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 survive extra-long main events.

The design of the arms was particularly well thought out to allow the use of identical suspension arms left/right at each end of the car, thus reducing your spare part needs and making servicing much quicker and easier.

The arm design was developed with “dirty” racing in mind… racing in heavy mud and rain. The smart design allows for the very quick and easy addition of mud protectors to both suspension arms. The arms feature openings at the bottom and side to allow optional mud protectors to be easily mounted to the arms.

Suspension Holders

The composite suspension holders are the lightest solution to keep weight as low as possible. The composite suspension holders also allow for suspension flex which is necessary to keep the car forgiving and easy-to-drive. The no-compromise design and special composite mixture used for the holders ensure that they are able to withstand abusive impacts and big jumps while keeping the geometry unchanged.

Suspension geometry is fully optimized and integrated into the suspension holders, so say goodbye to being lost with setups. The
suspension geometry has been optimized to ensure the best handling characteristics at typical tracks and standard racing conditions. The suspension holders feature preset 3° rear toe-in, 2° rear anti-squat, and 10° front kick-up. Both front and rear arms allow the use of wheelbase shims for quick and easy wheelbase adjustment.

For extreme high-competition racing conditions or for advanced off-road racers, optional alu suspension holders are available to allow fine suspension tuning.

Hardened 4mm and 3mm hinge pins are mounted through the suspension holders and locked with self-locking nuts. This suspension holder concept ensures that suspension pins will never come out during racing and moreover it ensures that the play between the arms and suspension holders will not change. The suspension holder concept reinforces the holding of the arms and in any crashes prevents the pin or arm from becoming disconnected.


The suspension arms and suspension geometry give a large amount of steering which is influenced by the different characteristics of Ackermann.

The angle of the tires during steering does not change as much as it does on the standard C-hub or pivot-ball suspension. Even when the suspension moves up or down the suspension ensures constant steering for easier, more precise and predictable handling into and in corners, and especially ensures fluent drive through the corners mainly on bumpy tracks.

Shocktowers and shocks were designed to complement with the suspension geometry.

Zero Kingpin Steering Blocks

The super-lightweight composite Zero Kingpin steering blocks are a genuine innovation in design and functionality. Each block features an inset steel bushing that is molded into the steering block itself, ensuring a wobble-free and ultra-tight steering block assembly.
This enables the kingpin screws to be firmly held in the steel threaded bushing while the end of the screw is self-locked in composite to prevent the screws from loosening during racing. The molded-in steel bushings allow the steering blocks to turn freely ensuring precise steering reaction. The super-tiny steering blocks are molded from a lightweight yet very strong and durable composite material.

The new-concept steering block is taken from 1/10 electric off-road cars and the XB808 to provide zero kingpin steering — the steering block rotates in an absolute vertical position so that the angle does not change. The new steering block gives a better steering radius which greatly improves the handling and makes the car even easier to drive on all tracks and provides more steering into corners. The steering block features one optimized Ackermann position.

The tiny size of the steering blocks was achieved by using super-light ball-bearings. The inner bearing (13×19) carries a heavier load where the CVD drive shaft outdrive rotates… while the outer bearing (8×14) is light to reduce unsprung weight. The two ball-bearings are ideally spaced to provide high stability to the mounting and holding of the wheel axle.

Caster Blocks

Each 1-piece caster block is very lightweight and with the new Zero Kingpin suspension geometry the car is equipped with one optimum preset 10° caster block. The optimized caster angle is integrated and non-adjustable. The angle of the caster block + the 10° angle of the front of the chassis with the suspension holders = total 20° caster of the car.

Rear Uprights

The rear uprights were designed to be small and lightweight. The low roll center position has been optimized to 1 position while the upper roll center positions feature 3 different roll center positions.

The tiny size of the upright was achieved by using light ball-bearings. The inner bearing (13×19) carries a heavier load where the CVD drive shaft outdrive rotates… while the lightweight outer bearing (8×14) reduces unsprung weight. The two ball-bearings are ideally separated to provide high stability to the mounting and holding of the wheel axle.

The outer suspension pin on which the rear upright sits features 2 shims which allow for wheelbase adjustment.

Composite Chassis Braces

The front and rear chassis braces have a significant influence on chassis stiffness and chassis flex and as such have great impact on car handling under different grip conditions. The 808E features well-proven and optimally-stiff composite braces for front and rear. These braces are more than up to the task… strong enough to hold the car together after heavy jumps or crashes to avoid tweak or breaking, yet still flexible enough to generate the proper grip for an electric-powered high-competition buggy.


The front and rear shocktowers are CNC-machined from premium extra-robust 4.0mm (front) and 3.5mm (rear) thick high-grade graphite to significantly reduce weight. The shocktowers featured optimized shock positions and roll center positions.

Centralized Design

With its narrow chassis design, all the internal parts of the 808E were positioned to keep everything as close to the centerline as possible while still keeping the center drivetrain in the most effective locations. To balance the weight of the motor and LiPo batteries, the center differential was optimally placed with the electronics strategically placed on a unique radio plate… all help to keep the weight as close to the center as possible. This centralized design provides superior side-to-side balance.

Tough, Durable, Ultra-smooth Drivetrain

Everything in the drivetrain is carried over from the latest spec of the XB808; CVD drive shafts through the all-new drivetrain layout; direct central shaft connection to the pinion gears; and of course the proper ratios to best utilize the power of today’s high-output brushless motors.

Since drivetrain weight and design have significant influence on the handling and performance of the car, drivetrain design was focused on for any improvements possible. The ultra-lightweight drivetrain has reduced rotating weight and exceptional performance. All drivetrain parts — drive shafts, diffs, brakes, outdrives — are ultra lightweight, strategically weight-reduced, and are manufactured from premium high-quality world-renowned HUDY Spring Steel™.

Direct Central Shafts Connection

The central drive shafts use a genuine XRAY innovation to transfer power from the motor. Both central drive shafts are directly connected to the pinion gears in the front and rear gearboxes. This allows direct transfer of power without any kinetic losses, as well as increasing the lifespan of the shafts thanks to the elimination of connecting parts. The drive shaft is inserted through the diff housing opening (with Labyrinth Dust Covers™ on the diff housings to keep the dirt outside) and a pin connects directly to the pinion. The connecting pin sits in a ball-bearing to guarantee that the connecting pin will never fall out… and removing the risk of having the central drive shafts become disconnected.

CVD Driveshafts

CVD drive shafts are lightweight yet still are the strongest that a buggy can be equipped with. All four CVD drive shafts are manufactured from exclusive HUDY Spring Steel™, the unique self-developed highest-strength material.

The CVD wheel axle is carried in the steering block and rear upright more safely thanks to the greater distance between both ball-bearings. Additionally, the CVD assembly is very secure and safe due to the connecting pin (which connects the shaft to wheel axle) being located within a ball-bearing, thus ensuring that the pin will never fell out… thus preventing drive shaft disconnections.

The wheel axle part of the CVD is additionally hand ground for maximum precision to ensure a perfect precise fit in both suspension ball-bearings… guaranteeing a perfect wobble-free fit and rotation.

Diff Housings

The chassis features rigid front and rear diff housings on which all suspension parts are mounted. With the new central dr
ive shaft design concept, both housings were redesigned to include Labyrinth Dust Covers™ for the central shaft bearings to keep dirt out. With the new design of the diff housings, internal areas are significantly reduced.

Easy access to both front and rear differentials makes maintenance super easy.


Rubber-sealed composite differential housings are manually precision ground after the molding process to guarantee a perfect fit with no vibration. Differential gears are made from pressed steel, heat treated, and machined for ultra-precision and smooth operation.

Diff outdrives are made from premium HUDY Spring Steel™ and the central diff outdrives are individually ground for highest precision. The diff outdrives are specially-hardened to increase the lifespan, and the diff outdrive area which is inserted into ball-bearing is additionally ground to ensure a very tight fit and precise rotation. The openings of the diff outdrives were designed to keep the drive shafts in the diff outdrives even during maximum suspension downtravel.

Wheel Axles

Wheel axles and wheel nuts are made from lightweight yet super-strong aircraft aluminum, hard-anodized for increased lifespan and low wear. The new suspension is slightly narrower which enables the use of optional offset wheel axles for fine-tuning your setup for particular racing conditions.

Diff Gears & Drivetrain Ratio

The main diff gears are all manufactured on a precision manual gear machine from HUDY Gear Steel… a material that was specially formulated and developed for use in gears. All the gears are hardened to provide the longest possible lifespan.

A wide range of different gears are available for perfect setup and adjustment for particular racing conditions.

Pinion gear are available in sizes of 13, 14, 15, 16, 17.
Spur gears are available in a range of 41T, 42T, and 43T.

The drivetrain ratio is optimized for the electric-powered 808E, allowing for aggressive acceleration and aggressive yet easier handling.

Front and rear differentials features 43T crown gears with 10T pinions making a 4.3:1 primary ratio. The central differential features 42T spur gear with a 17T pinion, making a 10.62 internal ratio.

The final ratio of the 808E is in the range of 10.37-14.22.

Center Differential Access

Access to the center differential is super easy by releasing the upper deck with only four screws. The low center diff housing is sized to accommodate optional spur gears and the stands are low to keep the weight as low as possible and to allow smaller central diff gears to be used.

Radio Case

With the no-compromise performance design in mind, the radio case components were developed for securely and quickly mounting LiPo batteries and associated electronics, and the composite radio case ensures great strength to sealability to protect sensitive radio gear.

The stands for the laydown steering servo are positioned near the chassis centerline. Heavy-duty steering horns are included to withstand the abuse from long mains.

1-piece Electronics Assembly

The 1-piece electronics assembly is compact and can be quickly & easily removed for very comfortable servicing and cleaning.

The large molded radio box features a very clean design and layout that locates the weight for proper balancing.

The LiPo batteries are placed to offset the brushless motor. The battery plate features slots for Velcro™-style battery straps and also a location for the speed controller.

For racers not using a radio switch, a handy rubber cover is included to help guarantee a leak-free radio box. The tight antenna tube holder ensures that the antenna tube stays attached even if the car flips.

Steering System

With the centralized design concept, the narrow steering stands were placed close to the centerline using very lightweight aluminum standoffs. The super-narrow steering plate is precision-machined from high-grade graphite, thus reducing unnecessary weight. The steering plate features several different Ackermann settings for precision steering setup.

The dual steering system rides on lightly-oiled ball-bearings, providing super-smooth and super-fast steering action. The strong servo saver spring makes sure that steering will be very precise in all conditions, but is still soft enough to ensure that energy will not be transferred to the servo even in heavy crashes. The strength of the servo saver can be easily adjusted through an adjustment collar; the collar is hard-anodized to prevent thread stripping in to dusty conditions.

HUDY Spring Steel™ Steering Turnbuckles

All turnbuckles in the 808E are manufactured from special HUDY Spring Steel™ material for turnbuckles, resulting in stronger turnbuckles with a tougher core. A handy turnbuckle tool is included.

With the narrow steering plate and narrow steering stands, the turnbuckles are perfectly sized. Relief steering ball-joints provide better fit into the wheels.

Big-Bore Shocks

Off-road performance depends very highly on perfectly-working shock absorbers. As such, all components and pieces of the 808E shocks were designed to obtain the best possible performance: shock bodies; pistons; shock cap; membranes; lower shock collar; rubber boots; internal shape; alu cap; springs.

A significant feature is the bore of the shocks, which was increased in the XB808 to allow for a higher volume of oil to flow for improved damping characteristics. Matching big-bore shock pistons were designed and manufactured with a special molding process to ensure optimum tolerance and roundness of the pistons so that they move freely and very precisely inside the shock body.

The front and rear shocks can be mounted in multiple positions on the shocktowers and arms; these positions were thoroughly tested and analyzed both in virtual reality as well on the tracks to offer the widest possible range of shock positions. This guarantees sufficient suspension travel and best setup for either flat European-style tracks or large bumpy US-style tracks.

Shock Parts

The big-bore shocks feature 18.5mm outside diameter shock bodies, externally threaded with an adjustable collar for downstops adjustment. The shock bodies are hardcoated, and features a new 1-piece alu shock cap.

The large 15.3mm inner diameter of the shock bodies ensures proper and consistent shock oil flow through the perfectly-round pistons which move very precisely inside the smoothly-finished interior of the shock body. The result is more consistent damping characteristics of the shocks.

The big-bore pistons are manufactured from well-proven specially-formulated composite material to provide smoother action and durability. The well-proven molding production process is used to ensure perfect roundness of the pistons after production, so that the pistons will move perfectly inside the shock bodies for identical shock action in all four shocks.

Wide shock membranes fit to the big-bore shocks. The improved material guarantees the same damping characteristics from the beginning of the race to the end even after excessive overloads.

The lower shock assembly ensures that the shock rod will move very freely inside the shock body but at the same time will minimize oil leakage and keeping the dirt away. Two shock O-rings – manufactured from a superior silicone compound to allow ultra-free movement of the shock rod while still maintaining a tight seal – are installed in the lower part of the shock body and are secured with composite shims. The entire lower shock assembly is secured with the new lower aluminum shock cap which makes assembly/disassembly quick and easy. The aluminum lower cap features an internal protective “dust foam” which keeps the dirt out.

The shock shafts are thick and robust to ensure they will handle any abusive racing conditions and big jumps. The 3.5mm thick shock shafts are precision machined from special high-
tensile steel and afterwards are ground for a super-smooth surface to ensure very free and smooth movement of the shock shafts in the shock bodies.

The shocks feature 8-hole (1.2 and 1.3mm) and 10-hole (1.1mm) conical pistons.

XRAY Premium Silicone Oils

The 808E features the new XRAY Premium Silicone Oils manufactured in Europe by a specialized premium silicone oil manufacturer; these new oils were exclusively created for XRAY. Each batch of premium oil is laboratory tested and calibrated to ensure the highest possible consistency and quality batch-to-batch. Based on the industry-standard cSt rating, the new line of oils will be easy to identify, adjust, and feel.

When following any setup sheets by XRAY or XRAY team drivers, you can be sure that the oils you will get for your car will be exactly same as used by the factory racing team, thus ensuring very exacting setups and handling of the car.

Motor Mount

The high-grade CNC-machined aluminum motor mount is machined from lightweight alloy and help dissipate motor heat. The motor mount features adjustable motor plate which allows super easy access from the top and allows quick and comfortable gear mesh adjustment.

Anti-roll Bars

Anti-roll bars are included to stabilize the car at both front and rear. The 808E anti-roll bars are easily mounted to the diff cases and can be adjusted through the adjustable linkages.

Front anti-roll bar have a thickness of 2.4mm and rear anti-roll bar have a thickness of 2.6mm. Anti-roll bar wires of different thickness are optionally available for fine-tuning your setup.


The aerodynamic rear wing is molded from a very flexible yet virtually unbreakable composite mixture. All edges are reinforced at critical areas to prevent cracking or breakage. The rear wing holders are mounted firmly to the rear shock tower. The rear wing holders offer many different wing-mounting positions for increased adjustability at different tracks.
