RX8 Platform.

Based on its ultra-successful predecessor, XRAY proudly presents the new RX8E. The new electric kit incorporates the latest improvements and refinements of the RX8 platform developed by the team and race-proven in high-competition races around the world.

Concept.

The RX8E is a typical XRAY: premium, professional, high-competition for the most demanding racers, developed with attention to the smallest details, and backed by premium service & support… a luxury masterpiece.

RX8E Compatibility.

With attention to the smallest details and a mandate to simplify servicing of the car, the all-new RX8E features cross-platform compatibility to ensure you can use the same car platform for both nitro and electric powered version making it either RX8 or RX8E. Most of the parts between RX8 and RX8E are fully compatible.

Chassis.

The new chassis is updated for the narrowed rear suspension configuration. The rear bulkheads are mounted 8.4mm closer together. The rear arm mounts move the inner pivot pins 2.5mm closer together, which combined with the bulkhead placement generates more rear traction and improves the stability of the car.

The chassis also features a unique, innovative front flex adjustment using a removable aluminum brace.

The chassis is narrower to increase chassis flex and generate more traction and steering. The narrower chassis also prevents chassis rub during cornering to help eliminate the feel of the car ‘stopping‘ in mid-corner.

Adjustable weight positions on both sides of the chassis offer quick & easy weight balance adjustment.

Chassis.

The chassis features cut-outs for the bulkheads, arm mounts, radio plate mounts, and front layshaft holder for perfect fitment and to ensure that these parts will always mount into the same precise position.

The outer edges of the chassis have been beveled and screw holes have been countersunk to provide a smooth lower surface with maximum clearance during cornering.

The lightweight chassis is CNC-machined from 5mm premium Swiss 7075 T6 aluminum, strategically machined in low-stress areas to make it as light as possible without affecting strength or rigidity.

Bulkheads.

The aluminum bulkheads provide optimal stiffness & flex for better steering characteristics, even with hard spec tires.

The super-lightweight Swiss 7075 T6 aluminum bulkheads have a very clean and lightweight design to give the lowest weight and CG, and still allow quick access to the driveline components for reduced maintenance downtime. 

Rear Bulkheads.

All-new rear bulkheads have been redesigned to fit the new composite bushings for the anti-roll bar bearings that eliminate the wear of the bulkhead. The rear bulkheads are an integral part of the rear suspension Multi-Flex™ system that offers the choice of different flex adjustments.

The rear bulkheads are CNC-machined from premium Swiss 7075 T6 aluminum to provide the lightest & strongest framework for the car.

Front Bulkheads.

All-new front bulkheads have been redesigned to fit the new composite bushings for the anti-roll bar bearings that eliminate the wear of the bulkhead.

All-new graphite upper arm holders feature new positions for the eccentric bushings that position the upper pins 2.5mm narrower to work with the new rear lower arm mount position.

The rear upper arm holders are machined from strong 3.5mm graphite material for optimal flex of the rear suspension. Both front & rear mounts are attached to the rear upper bulkhead clamps.

Shock Towers.

The rear shock tower was redesigned to mount to the new rear narrower bulkheads and to compliment the updated suspension geometry.

Both front & rear shock towers have updated shock mounting positions. The towers are made from thick 3mm graphite material for maximum durability.

Front Wire Anti-roll Bars.

All-new front wire anti-roll bar was redesigned to work with the new adjustable system that allows easier adjustment of the bar as well as remove any excess play from the system.

The RX8E includes both wire & blade-style front anti-roll bars for freedom of choice based on track conditions.

The wire anti-roll bar is used to increase steering response on small, technical tracks. The wire bar is mounted to the bulkheads from the outside to allow quick & easy changes and adjustment. The wire bar turns in ball-bearings for maximum precision and freedom of movement. Anti-roll bar height can be adjusted quickly & easily.

Rear Anti-roll Bars.

All-new rear wire anti-roll bar was redesigned to work with the new adjustable system which allows easier adjustment of the bar and reduces play.

The rear 2.8mm anti-roll bar helps to reduce rear chassis roll. The roll bar turns in ball-bearings for maximum precision and freedom of movement. For fine tuning, optional wires of different thickness are available. Anti-roll bar height is adjustable via a screw… quick & easy.

Axles & Outdrives.

The all-new rear solid axle shaft and lightweight composite pulley were redesigned to fit the new narrow positions of the rear bulkheads. All outdrives are manufactured from HUDY Spring Steel™ and are specially ground for maximum precision. All pulleys have self-cleaning holes to reduce buildup.

The front 1-way and rear solid axle are small and light, ensuring super-low rotating mass and lowest CG. The super-lightweight front 1-way bearing is inserted directly in the axle, and the axle body is machined from Swiss 7075 T6 aluminum.

Pivot Balls.

The all-new rear pivot balls were lengthened to work with the new lower rear arm mounts to still achieve the desired vehicle width.

The RX8E pivot ball suspension contains precision pivot balls that are specially hardened to better withstand harsh crashes and extend their lifespan. A total of eight (8) pivot balls are included and are captured by strong M10 composite nuts to minimize weight and give smooth suspension movement.

Standard pivot balls are made from steel for maximum durability and lifespan. For those who are focused on minimizing unsprung weight, optional lightweight aluminum and titanium pivot balls are available.

Shock Springs.

The RX8E comes equipped with C7.5 front springs to provide maximum stability and steering, and C5.6 rear springs to provide maximum traction & cornering speed. 

The RX8E springs, like all the other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics

Belt Tensioner.

The adjustable side-belt tensioner is captured on a graphite plate, mounted to the side of the radio plate mount. The smart design allows the side-belt tensioner to be easily adjusted, or easily removed for engine removal.

Integrated Belt Tensioning.

Rear upper clamps feature integrated belt-tension adjustment using adjustable bearing eccentric holders, eliminating the need for a separate belt tensioner. All ball-bearings turn in composite hubs to reduce friction and improve drivetrain efficiency. 

Drive Shafts.

The tiny drive shafts are manufactured from HUDY Spring Steel™, the most effective drive shaft material by the industry leader HUDY. Self-developed HUDY Spring Steel™ ensures the longest drive shaft life, maximum strength, and lowest weight.

The front of RX8E is driven by CVD driveshafts, while standard dogbones are used in the rear.

Hardened with a proprietary process, the drive shafts provide unbeatable lifetime and reliability.

Pulleys.

All pulleys are molded from a special composite mixture to ensure low-friction operation, efficient and strong tooth profiles, and long lifespan. Pulley covers feature self-cleaning holes.

PUR® Drive Belts.

The drivetrain is operated by PUR®-reinforced high-efficiency low-friction drive belts, which ensure that all power is properly and efficiently transferred to all drivetrain parts.

Spur Gears.

The small 2-speed allows the use of smaller spur gears from the well-proven NT1, allowing fast acceleration and low rotating mass.

The spur gears are made from graphite material for improved durability. The special graphite material is also very light which helps to decrease the weight of rotating parts for improved acceleration.

The spur gears are molded with a special technique allowing the gears to be absolutely true, thus improving the drivetrain efficiency. Each gear is stamped with a tooth number for easy identification.

Suspension Geometry.

The RX8E features the most advanced, race-engineered suspension geometry for nitro on-road car racing and is designed to provide responsive racing characteristics under all racing conditions.

Over the years XRAY has successfully gained and utilized extensive suspension geometry knowledge and self-developed suspension stiffness technology, which have been used with great success in electric & nitro cars, both on- and off-road. 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.

Integrated Suspension Settings™.

The design of the RX8E features I.S.S. (Integrated Suspension Settings™). All adjustment possibilities are completely integrated, allowing complete set-up changes without changing or replacing any parts. The use of square eccentric bushings in the front bulkheads, as well as in the rear bulkheads for upper & lower suspension, allows for complete geometry adjustment. Roll centers are adjustable in the standard upper & lower positions, as well as in inner and outer positions. High-tensile steel suspension pivot pins are polished for smooth suspension action.

Adjustable Axle Height.

Front steering block and rear uprights feature concentric and eccentric bushings which allow roll center adjustment as well as positive caster adjustment in front. The eccentric bushings in the rear upright also allow independent wheelbase adjustment. The height of front and rear axles can be easily adjusted with eccentric bushings.

Wheelbase & Weight Balance Adjustment.

Wheelbase can be easily adjusted using clips on the front suspension. Moving the arms towards the front or rear can also be used to fine-tune weight balance.

Offset Adjustment.

Wheel offset is easily adjustable by 0.5–2.5mm using included shims. This affects steering adjustment (when adjusted at the front) and also rear traction characteristics (when adjusted at the rear).

FRONT - Less offset at the front gives more in-corner steering and improved steering response. Recommended for small technical tracks.

More offset at the front gives more stability and makes the car easier to drive on large tracks or under high-grip conditions.

REAR - Less offset at the rear gives more in-corner steering, but less rear traction and stability. Therefore it is recommended to use less offset on small technical tracks or under high-traction conditions.

More offset at the rear makes the car more stable and improves cornering speed.

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 RX8E suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry of suspension points, and materials used… all these concepts and details have been thoroughly reviewed to create optimal suspension arms.

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 provide extreme durability.

Steering Blocks.

The tiny, tough steering blocks are molded from a special composite mixture for maximum strength. Thanks to perfect molding, bearings fit into the steering blocks without any extra play for maximum stability and steering.

The included 0° kingpin steering blocks allow the mounting of optional graphite aerodynamic disks which improve both low & high-speed steering, and improve stability in high-speed corners.

The steering block extension is mounted to the steering block, and features 3 different Ackermann positions. The kit includes 2mm bump steer shims for optimized bump steer characteristics; bump steer can be easily changed by adding or removing shims.

The extensions for steering blocks are made from Swiss 7075 T6 aluminum for increased durability and unmatched lifespan.

Rear Uprights.

The small, compact rear uprights are very strong due to the special composite mixture used. Thanks to perfect molding, bearings fit into the rear uprights without any extra play, giving maximum stability and handling.

The rear uprights allow mounting of optional graphite aerodynamic disks which improve, improve rear traction, and improve stability in high-speed corners.

The rear uprights feature two easily-adjustable upper roll center positions which are used for traction adjustment. The uprights also feature two body mount adjustment positions depending on the type of body used. Also included are shorter and longer pivot ball joints for optimum set-up adjustment.

Body Posts.

Front body posts are machined from premium Swiss 7075 T6 aluminum and are additionally lightened for minimal weight.
