Team Xray XB8E 2017 Edition

Team Xray XB8E 2017 EditionBased on the ultra successful XB8 nitro buggy platform, Team Xray proudly presents the 2017 spec XB8E which incorporates the latest improvements and refinements gathered by the team, race-proven in the highest competition races around the world. Updates include large volume differentials with improved gears and lightweight machined outdrives, new graphite material servo saver, improved steering geometry, longer rear suspension arms, composite front upper deck, and much more. Check out the full details and see the pictures of the new XB8E 2017 below.

Gear Differential
The all-new, high-volume Team Xray XB8E 2017 differentials were redesigned to increase diff reliability and performance. Differentials feature higher oil volume capacity cases, and all-new larger internal gears with more teeth for improved differential moment. The larger volume of the differential and the shape of the gear teeth reduce oil overheating. To increase reliability, diff pins have a new, stronger design. The new differentials give increased traction and reliability, especially in long runs.

Internal Diff Gears
All-new Xray XB8E 2017 internal diff gears were created to increase differential reliability and reduce diff oil overheating. The new 20T and 10T gears have a larger size and a greater number of teeth to ensure more precise fitment and engagement. Pressed-steel differential bevel and satellite gears are heat-treated and machined for superior precision and smooth operation.

Diff Outdrives
Updated XB8E 2017 diff outdrives were created to accommodate the new stronger diff pins. The front longer diff outdrive adapters ensure that the drive shafts will not fall out in extreme crashes at full steering lock. To reduce rotating weight, the super-lightweight diff outdrives are machined from HUDY Spring Steel™ which allows unnecessary material to be removed to further reduce weight without affecting durability. The inner portions of the outdrives are additionally hand-ground for maximum precision and fitment into the diff case. All outdrives are hardened using HUDY’s own special hardening process for extended lifespan and reliability.

Steering Blocks
New XB8E trailing-axle steering blocks offer a significant handling improvement in all track conditions, making the car easier to drive and giving increased forward traction. The smart design of the steering block allows one steering block to be used either on left or right side for easy servicing. All-new steering plates change the front suspension geometry and thus change steering characteristics as well. The new updated geometry results into more linear and precise steering, making the XB8E more predictable and easier to drive.

Steering System
To increase servo saver reliability, especially in dusty conditions, the all-new XB8E 2017 servo saver is moulded from new graphite material which 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 Swiss 7075 T6 aluminum steering plate. Ackermann is easily adjusted by quickly & easily changing steering link mounting positions on the steering plate. Bump steer is easily adjusted by inserting shims between the steering plate and steering linkage.

Upper Deck
The front upper deck is now made of molded composite material to improve flex which results in increased traction and improved steering characteristics.

Suspension Arms
All-new longer rear arms make the car easier to drive in most track conditions. The new rear arms also give flex to help generate more traction and give better handling. All-new, narrower front lower arms move the arms more frontwards, resulting in improved weight balance. XB8E suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry, and materials used… these are all part of the concepts and details that are thoroughly reviewed to create optimum suspension arms. The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough for extreme durability. The exclusive composite mixtures used for suspension arms offer a perfect balance between reliability & performance.

I.S.S. Suspension Holders
To accommodate the longer rear suspension arms, narrower aluminum suspension holders are used. The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.) which allows for quick & 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.

Weight Balance
An all-new, improved weight balance was created by moving the XB8E 2017 front lower suspension arms more frontwards. This new weight balance makes the car easier to drive, increases predictability, makes the car extremely resistant in rough parts of the tracks, and gives great handling in jumps and fast parts of the track.

Side Guard Braces
All-new optional side guard braces allow for very efficient and easy chassis flex adjustment to adjust the handling of the car to different track conditions. By adding the graphite braces, the entire chassis is reinforced and stiffer flex will improve handling in high-traction conditions.

Chassis
The XB8E chassis is CNC-machined from 3mm high-quality Swiss 7075 T6 aluminum, strategically machined, and then anodized to make it as light as possible without affecting strength or rigidity. Non-essential material below the engine, fuel tank, and differential was removed to allow for the lowest possible center of gravity and appropriate chassis flex. The rear of the chassis is wider to increase stability, and the front is narrower to improve steering. The short chassis has weight balance frontwards (including motor, electronics, batteries, and center diff).

Side Guards
Side guards incorporates a larger bottom radius to make the car more stable on rough tracks. The radius on the side guards increases the car’s longitudinal flex. The side guards are moulded from a special composite mixture for increased flex that helps generate more traction. The tough composite side guards protect the car from side impacts. The side guards perfectly fit the chassis and seal against dirt.

Chassis Braces
Front and rear XB8E chassis braces have a significant influence on chassis stiffness and flex, and as such have great impact on handling under different grip conditions. The rear brace has a direct mounting to the rear bulkhead instead to the rear shock tower. The mounting to the bulkhead eliminates transfer of vibrations and energy from the suspension via shock towers. This helps to improve landings and generates more off-power traction. The rear brace is moulded from a medium-stiff composite mixture for better flex & rigidity, and allows the mounting of optional graphite inserts to reinforce the chassis brace to make it even stiffer (suitable for high-traction conditions).

Battery Plate
The battery plate design allows to install the plate either frontwards or rearwards thus to position the batteries either frontwards or rearwards with a significant influence on the weight balance adjustment. The battery plate itself has sufficient space to move slightly the battery pack more rearwards or frontwards. The rear of the plate has a dedicated area for a speed controller placement. The Velcro strips are included for comfortable battery mounting.

Electronics Weight Balance
To adjust the weight balance the heavy battery pack can be easily moved either frontwards or rearwards. FRONT = More weight in front = Less rear traction REAR = Less weight in front = More rear traction

Suspension Concept
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 & 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 and applied extensive knowledge of suspension geometry & stiffness, all of which has been carefully considered while designing suspension parts. The ultra-lightweight suspension parts are molded from special composite materials that make the parts very light, yet very durable to withstand the rigors of high-performance racing.

Front Upper Arms
Moulded from a softer composite mixture, the front upper arm has increased flex in all directions to generate more traction. This also improves handling on rough or destroyed tracks. Caster is easily adjusted using caster clips that are inserted either in front or behind the front upper arms.

Rear Uprights
The XB8E 1-piece rear upright features geometry that allows it to generate more traction and better absorb bumps. The smart design allows the same upright to be used on both left & right sides. The upright allows adjustment of the upper roll center by 3 different positions, and lower roll center by 2 different positions. The lower suspension pin on which the rear upright sits features 2 shims for wheelbase adjustment.

Pivot Balls
To reduce weight and lower the CG, all-new XB8E 2017 front upper pivot balls are combined with steel threaded part for maximum strength. The aluminum ball is machined from premium Swiss 7075 T6 and additionally hardcoated for extended lifespan.

Bulkheads
The all-new diff bulkheads were reinforced, updated, and redesigned to accommodate the repositioned Ackermann and to fit the rear brace mounting holder. 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.

Drivetrain
The XB8E is a conventional shaft-driven 4WD off-road car featuring: Front & rear gear differentials with adjustable oil viscosity, featuring 46T crown gears and 14T pinion gears Central differential with adjustable oil viscosity, featuring 46T spur gear Front & rear universal drive shafts, and central CVD drive shafts

Diff Gears & Drivetrain Ratio
Differential main gears are manufactured from HUDY Gear Steel on a precision manual gear machine. This material was specially formulated and developed for use in gears. All gears are hardened to provide the longest possible lifespan. A wide range of different gears — spur gears and pinion gears — are available for perfect set-up and tailoring to particular racing conditions. All drive shafts are manufactured from world-renowned HUDY Spring Steel™, resulting in some of the world‘s thinnest yet most durable drive shafts used in off-road cars. All drive shafts and outdrives are hardened with a proprietary hardening process to provide unsurpassed lifespan & reliability. The central larger & stronger outdrives feature protective rubber boots, thick 3mm pins, and protective locking rings.

Turnbuckles
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, making them very well suited for the steering system and rear upright linkages.

Wheel Hubs
Ultra-lightweight 17mm wheel hex drive hubs are CNC-machined from Swiss 7075 T6 black-coated aluminum. The alu hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting.

Center Diff. Access
Access to the center differential is quickly and easily accomplished by removing eight screws. 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.

Radio Plate
The XB8E 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 motor mount machined from Swiss 7075 T6 and is 2mm wider compared to older version for improved durability.

Anti-Roll Bars
Anti-roll bars used to stabilize the car are manufactured from spring steel material. The front & rear roll bars are easily mounted to the diff cases, and can be adjusted through adjustable linkages. Anti-roll bar wires of different thickness are optionally available for fine-tuning your set-up.

Shock Towers
Aluminum towers are CNC-machined from premium Swiss 7075 T6 and then additionally black coated. The stiffer alu shock towers give better performance at high-traction tracks. Optional graphite shock towers offer more flex to generate more traction, and are recommended for low-traction tracks.

Shocks
Oversized big-bore shocks feature 16.2mm I.D. shock bodies which are externally threaded for use 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. 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 use. The lower shock assembly ensures very free movement of the shock rod 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 & easy. Thick, robust shock shafts will handle all abusive racing conditions and big jumps. The 3.5mm thick shock shafts are precisely machined from special high-tensile steel, and afterwards are ground to a super-smooth finish to ensure smooth movement.

Shock Springs
XB8E shock springs offer a mix of progressive & linear characteristics. XB8 springs are slightly progressive, but under more compression change characteristics to become more linear. This gives excellent feeling & feedback of the car in all different track conditions. 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. Ultra-precise shock pistons feature 6-, 8- and 10-hole options. The big-bore pistons are molded from tough, well-proven Delrin® material to provide 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 four shocks.

Body
The XB8E body has the desired aerodynamics, downforce, and side stability that ensures proper landing of the car, and with high rear downforce making the XB8E racing body unbeatable in performance design. Produced from high-quality, premium Lexan™ material. The XB8E body comes from the XB8 platform.

Wing
The stylish and effective rear wing was designed to provide the appropriate amount of downforce and generate required stability for the car. Made from a strong special composite mixture, the wing was designed to survive severe abusive and extreme crashes while keeping its shape. Rear wing holders are made from a special composite mixture to withstand abuse and crashes, and feature several different wing mounting positions.
