Team Xray XB8E Officially Unveiled

Team Xray XB8EThe engineering department at Team Xray have been burning the midnight oil to get their finish their latest RC project, meet the new Team Xray XB8E! The XB8E is the next evolution of the XRAY off road concept transforming the successful XB8 platform into the electric powered XB8E. Featuring superior weight balance and weight distribution and more forgiving and easy-to-control handling, the Team Xray XB8E is ready to set a new standard in the 1/8 electric powered class. Check out the RC car pictures after the jump!

The Team Xray XB8E chassis is CNC-machined from high-quality Swiss 3mm 7075 T6 aluminum, which is strategically machined in low-stress areas and is then anodized to make it as light as possible without affecting strength or rigidity. All screw holes on the bottom of the chassis are countersunk, allowing for a very smooth chassis underside with no protruding screw heads.

Side Guards
The XB8E side guards have an updated design to compliment the new redesigned chassis. The tough composite side guards offer improved side protection, and fit perfectly to chassis to seal against dirt.

Electronics Layout
The layout of the Xray XB8E’s electronics was designed to focus specifically on weight distribution and balance. The center differential with motor mount, as well as the receiver box, were moved more forward for better weight balance compared to the previous versions.

Radio Plate
The receiver box is mounted on the same graphite plate as the servo. The graphite plate is connected the chassis by an aluminum holder and stand that can be easily removed from chassis for cleaning and maintenance. You need only to remove 3 screws from the bottom of the chassis to remove servo and receiver box.

Motor Mount
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 and easy motor rotation to adjust gear mesh, and yet clamp. The Xray XB8E motor mount is machined from Swiss 7075 T6 and is 2mm wider compared to older version for improved durability.

Battery Plate
XB8E includes composite battery holder with higher barriers to eliminate the movement of the batteries. The rear of the plate has a dedicated area for a speed controller placement. The Velcro strips are included for comfortable battery mounting.

The XB8E is a conventional shaft driven 4WD off-road car featuring front and rear gear differential with adjustable oil viscosity with 46T crown gear and 14T pinion gear, central differential with adjustable oil viscosity with a 46T spur gear as well as front, central, and rear CVD drive shafts

Drive Shafts
Team Xray XB8E 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 off-road cars. The central larger and stronger outdrives feature protective rubber boots, thick 3mm pins, and a protective locking ring. All drive shafts and outdrives are hardened with a proprietary hardening process to provide unbeatable lifetime and reliability.

Diff Outdrives
To reduce rotating weight, the super-lightweight diff outdrives are machined from HUDY Spring Steel material which allows additional material to be removed from the outer part of the outdrives, further reducing the weight without effecting 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 XRAY’s own special hardening process to provide extended life time and reliability.

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

Diff Bulkheads
The XB8E bulkheads were reinforced in all necessary areas to withstand the rigors of racing and extreme impacts. The diff bulkheads are an important chassis component, housing both the front and rear differentials and providing mounting points for the suspension mounts and shock towers. The bulkheads have been designed for extreme durability, while still providing easy access for tuning and maintenance.

Suspension geometry is one of the most important features of any RC model car, yet at the same time is also one of the most difficult and challenging features for a designer to create and perfect. From arms and suspension blocks, to light-yet-robust steering blocks, every suspension part has been specially designed for 1/8 off-road racing to provide responsive handling and performance characteristics under all racing conditions. Over the years, XRAY has successfully gained, utilized, and applied extensive knowledge of suspension geometry and stiffness, all of which has been carefully considered while designing suspension parts. The XB8E’s ultra-lightweight suspension parts are molded from a special composite material that makes the parts very light yet very durable to withstand the rigors of high-performance racing.

I.S.S. Suspension Holders
The Team Xray XB8E aluminum suspension holders feature Integrated Suspension Settings (I.S.S.) which allows for quick and easy suspension geometry setting. Using eccentric suspension bushings inserted into aluminum suspension holders – as well as additional suspension shims – the XB8E suspension geometry can be completely adjusted in mere seconds.

Pivot Ball Suspension
XRAY Pivot Ball Suspension XPBS is a uniquely innovative concept, and smart R&D design. The ultra-robust pivot ball suspension has integrated suspension geometry adjustment, with different kingpin plates being the only optionally-available tuning parts.

Suspension Arms
Suspension arms are one of the most important parts of any RC model car, as they directly influence the handling and responsiveness of the car. XB8E suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry of suspension points, and material characteristics… all these aspects and details had to be thoroughly reviewed to create optimal suspension arms. Based on extensive knowledge gained from previous XB-series cars, several different suspension arm designs were tested in both virtual reality and in-car to determine the best final designs. 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.

SFA Graphite Stiffeners
SFA graphite stiffeners allow for super-quick suspension flex adjustment to easily adjust the traction of the car in various track conditions. Whether you drive in low or high traction conditions, with the smart SFA graphite stiffeners you can very quickly and easily adjust your car to suit current conditions. At the beginning of a race event when traction is low, the arms are used without the SFA graphite stiffeners. As traction increases, the suspension can easily be made stiffer by mounting the SFA graphite stiffeners for more stability and easier driving characteristics. The SFA graphite stiffeners give the car maximum stability in chicanes and allow for easier and smoother steering. The graphite stiffeners are recommended for use at big jump tracks and also when the weather temperature is 30°C or higher. Made from high-quality CNC machined graphite material, the stiffeners can be easily mounted or removed by only a few screws.

Steering Blocks
The XB8E steering block consists of a super-lightweight composite steering block and stiff Swiss 7075 T6 kingpin plate. The steering block is mounted via massive pivot balls into the upper & lower arms. The upper pivot ball is mounted into an adjustable upper ball joint and via roll center shims to the kingpin plate; this assembly allows camber and upper roll center adjustment. Using shims of various thicknesses, the upper roll center can be adjusted quickly and easily. The lower pivot ball is mounted into the steering block via an adjustable alu nut and composite bushing. By adjusting the pivot ball, both track-width and camber can be adjusted.

Rear Uprights
The ultra-tiny XPBS rear uprights are unique , innovative, smart… an authentic XRAY innovation. The rear upright consists of a super-lightweight composite upright block and stiff Swiss 7075 T6 mounting plate. The uprights were designed to have the smallest design with minimal weight, yet be strong enough to survive rigorous impacts. The upper roll center plate has a unique design that allows easy changing of roll center position. The roll center plate features 2 roll center positions, so by placing the plate the opposite way another 2 roll center positions for super-fine tuning are available. The roll center shifting is in range of 2.5mm. The roll center height of the upper camber link can be adjusted via shims of various thicknesses. The composite upright features 2 lower roll center positions. The outer suspension pin on which the rear upright sits features 2 shims which allow for additional wheelbase adjustment.

Suspension Additional Weights
The smart design of the Team Xray XB8E steering block and rear uprights allows for the mounting of optional weights. To increase the stability of the car, optional brass weights can be mounted directly under the steering blocks and/or rear uprights to further lower the CG. Easy & smart… totally XRAY.

Front Upper Suspension
The front upper suspension is part of the innovative and unique XPBS suspension concept. Extra-strong and robust front upper arms are mounted to the front bulkhead assembly into the front shock tower and adjustable suspension holder. Using eccentric bushings, front inner upper roll center can be easily adjusted. Caster is easily adjusted using caster clips which are inserted either in front or behind the front upper arms. The ball link is inserted into the upper arm and the integrated adjustable turnbuckle can be accessed from outside for quick & easy camber link adjustment.

Aluminum Hex Hubs
Ultra-lightweight 17mm wheel hex drive hubs are CNC machined from Swiss 7075 T6 black-coated aluminum. The aluminum hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting. To adjust the track width optional offsets are available -0.75mm, 0mm, +1.00mm and +2.00mm.

A full set of 22 high-speed, blue-sealed ball-bearings are used throughout the drivetrain to ensure maximum efficiency.

Shock Absorbers
The Xray XB8E big-bore, long-stroke shocks have a special construction that gives ultimate reliability and performance. These new shocks have had all parts fully redesigned and adjusted to take advantage of the big-bore design. The oversized big-bore shocks feature 18.5mm outer diameter shock bodies, 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 longer shock shafts and shock collar combine to give increased downtravel. Ultra-fine shock protective rubbers give superior sealing against dirt. The large 16.0mm inner diameter of the shock bodies ensures proper and consistent shock oil flow through the perfectly-round pistons while they travel inside the smoothly-finished interior. The result is more consistent damping characteristics.

The big-bore pistons are molded from tough, well-proven Delrin® material to provide smoother action and durability. The precision molding production process ensures perfect roundness of the pistons after production, so that the pistons will move smoothly inside the shock bodies for identical action in all four shocks. The specially-formulated rubber material of the shock membrane ensures equal damping characteristics from the beginning of the race to the end, even after extreme operation.

The lower shock assembly ensures that the shock rod will move very freely inside the shock body, while at the same time minimizing oil leakage and keeping dirt out. 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 lower aluminum shock cap which makes assembly/disassembly very quick and easy.

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

Shock Springs
XB8E springs have been specifically designed to complement the big-bore shocks. These XRAY shock springs, like all other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics. Spring rate is not constant, but rather the spring rate progressively gets heavier the more the spring is compressed. As the car initially enters the corner, the spring works like a softer spring to provide maximum traction. As the chassis begins to roll in the middle of the corner, the spring rate progressively increases until it works like a stiffer spring which allows the car to maintain maximum cornering speed.

HUDY Spring Steel Turnbuckles
To guarantee maximum reliability all turnbuckles are manufactured from special HUDY Spring Steel™ material for turnbuckles with a tougher core. These turnbuckles are used for front and rear upright linkages, steering system as well as for the servo saver.

Shock Towers
The front shock tower has been updated with new front roll center positions for updated suspension geometry and the rear shock tower has been redesigned to fit the optional longer chassis brace. Machined from extra thick premium-grade graphite, the shock towers are lightweight and strong. Front and rear shock towers include multiple shock positions as well multiple roll center adjustment positions. The rear shock tower also holds the wing mount.

Dual Arm Steering System
The Team Xray XB8E buggy’s dual arm steering system is very simple yet effective and features an integrated easily adjustable servo saver. Ackermann is easily adjusted by quickly and easily changing steering link mounting positions on the steering plate. Bump steer is easily adjusted by inserting shims between the graphite steering plate and steering linkage.

Chassis Braces
The front and rear braces have significant influence on chassis stiffness and chassis flex and as such have great impact on car handling under different grip conditions. The XB8E features the well-proven 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 needed grip. The longer rear chassis brace increases the stiffness in the longitudinal direction while allowing the car to flex more to the sides.

Front Braces
The stiffness of the front suspension is easily adjusted to accommodate the particular track traction, even if the traction changes during the race the stiffness is very easily adjusted. For slippery and low-traction tracks, the front composite brace may be removed and an optional reinforcement alu stand connects the front upper deck to the radio plate. This configuration generates more traction. For low- and medium-traction tracks, we recommend using the front composite brace only. For high-traction and hard-packed tracks, both the front brace and reinforcing alu stand are recommended to make the front suspension extra stiff.

Rear Braces
The longer rear chassis brace included in the kit increases stiffness in the longitudinal direction and gives the car more side flex. An optional rear short chassis brace provides more longitudinal flex and reduced side flex. The smart design of the car allows both long & short braces to be mounted at the same time which makes the rear of the car very stiff and is suitable for extremely large jumps to protect the chassis from deformation on landing.

Center Differential Access
Access to the XB8E center differential is quickly and easily accomplished by removing four screws from the upper differential plate. The lower center diff mount is sized appropriately to allow the use of the optional spur gears, while keeping the mass as low as possible.

Anti-Roll Bars
Anti-roll bars are manufactured from spring steel material and are included to stabilize the car at both front and rear. The roll bars are easily mounted to the diff cases and can be adjusted through the adjustable linkages. Both front and rear anti-roll bars have a thickness of 2.4mm. Anti-roll bar wires of different thickness are optionally available for fine-tuning your setup.
