Chief Engineer, XRAY

Since the release of the first T1 in 2000, XRAY has become synonymous with quality, workmanship, performance, and luxury in the RC world. With countless victories and titles from all around the world — including 30x US National Champion, International Indoor Champion ’05-’06-’07-’08-’09, US Snowbird Champion ’04-’05-’06-’07-’08-’09-‘10, 3x European Junior Champion and over 200+ national titles around the world — XRAY touring cars have become the world’s most favorite touring car as voted in the Reader’s Choice Awards and more than 12x Car of the Year Awards. Over the years, XRAY’s Engineering Department has continued its ongoing development, bringing with it a fresh new version of its touring car platform, always superseding and improving upon its predecessors.

The new T3 platform is the next evolution of XRAY’s highly-successful touring car platform which had its roots in the T1 (introduced in 2000) and the T2 platform (introduced in 2005). With the latest advancements in electronics, motors and especially batteries (bringing the new standard of LiPo batteries), the T3 has been purposely designed as a new modern platform optimized to incorporate and accommodate these new developing standards.

The T3 packs in all of the latest parts and products supporting the car’s high-performance nature to gain a distinct edge in the highly-competitive spectrum of foam- and rubber-tire racing.

The new T3’11 was designed to work seamlessly with new technology and therefore is specifically designed for high-performance LiPo batteries. Everything around the car was optimized and specially designed for the best balance of the car using the LiPo batteries.

The new double steering system is ALL NEW for XRAY electric touring cars. The double steering system is supported by 6 ball bearings and runs on aluminum stands. Ackermann is easily adjusted by inserting shims between the steering plate and steering rods. The new steering system features a lower mounting position for steering linkage which makes the car handle easier going into corners. Handling is easily adjusted for more aggression by inserting a shim between the steering block and steering rods.

The smart top desk and double steering system design allows the servo to be placed in a horizontal orientation along the chassis. This allows for a more centered placement of electronics in the car, along with having the servo saver in the center of the chassis.

The T3’11 features a unique servo saver position ; in the absolute center of the chassis. The servo saver consists of 3 springs which makes the servo saver strong enough to prevent extreme steering deflection from impacts, while at the same time being flexible enough to prevent servo damage in hard crashes. The servo saver has interchangable bushings to fit most popular servos on the market.

The T3’11 steering is independent of chassis flex due to the fixed mounting of the alu stands, which are independent from chassis flex. This creates flex-free steering which is always very precise and keeps the car under total control all the time.

To increase the stiffness of the car, additional (included) alu stands can be mounted between the steering stands and the top deck. This makes the car stiffer and results in less turn-in steering, while at the same time makes the car easier to drive in high-grip conditions.

The top deck has been completely redesigned to fit the new LiPo chassis design and the new dual steering system. The shape of the top deck has been specifically designed to achieve maximum steering, traction, and cornering speed. The top deck is machined from high-grade 2.0mm graphite and features XRAY Multi-Flex Technology™ adjustment positions. An optional belt tensioner can be mounted to the top deck.

With the current trend of high development in the electric motor and battery industries, the drivetrain has been optimized to work efficiently with all most popular motors — stock, modified, and brushless. As such the T3 comes with 38T diff pulleys and large 20T center layshaft pulleys.

T3 constant velocity drives (CVDs) are exclusively manufactured from special world-renowned, top-secret, self-developed HUDY Spring Steel™. The T3 drive shafts are the world‘s tiniest yet most durable drive shafts used in electric touring cars.

The drive shafts are strategically lightened – see the hollow end of the dog bone – to guarantee the lowest possible weight without compromising strength or durability. These specially-lightened drive shafts can only be manufactured from special HUDY Spring Steel™ which was developed for extreme racing conditions. The drive shafts have been additionally hand-ground for maximum precision and to provide true rotation and unbinding drivetrain operation.

Rotating mass is one of the most significant influences on the performance of an RC racecar. The T3’11 features a unique lightweight composite XRAY Front Solid Axle. The Front Solid Axle has a very stiff structure and ultra-light weight that was achieved by molding the entire solid axle from XRAY’s own self-formulated composite material.

Outdrives are fully exchangeable which allows very easy and comfortable servicing, while the unique drive shaft connection — eliminating the former drive shaft blades — enables direct power transfer to the axle and eliminates play between the drive shaft and outdrives, improving steering precision and increasing overall steering.

The T3‘11 features a high-competition, super-smooth Aluminum Ball Differential. Manufactured from the premium Swiss 7075 T6 and additionally hard anodized to increase the lifespan of the outdrives. The differential is externally adjustable and comes factory pre-assembled.

XRAY’s innovative and smart Labyrinth Dust Cover™ diff protection system has been carried over from previous T1/T2 platforms where it has been very successfully used for many years. The special internal labyrinth design of the diff covers prevents dirt, debris, and carpet fibers from getting into the differential, thus reducing servicing and ensuring long life.

The XRAY Aluminum Ball Differential features carbide balls and a high-quality carbide thrust-bearing for ultra-smooth running.

Ultra-lightweight bulkheads were designed to get maximum traction, steering, and balance. All bulkhead parts are CNC-machined from premium Swiss 7075 T6 aluminum and are strategically machined to provide the lightest possible support framework for the car. Thanks to the ultra-low platform it was possible to create the smallest, and lightest bulkheads ever. The bulkheads are anodized in a distinctive orange color. (Note: Color may vary slightly between products.) XRAY’s legendary attention to detail is noticeable in all the precisely chamfered edges.

XRAY’s attention to detail and perfection is evident with their TQM (Total Quality Management) approach. Not only are all bulkheads inspected during the production process, but they are also mounted to the chassis to verify that the car’s “backbone” has been perfectly manufactured. So when you open the box, you will see and appreciate the beauty.

The motor mount is connected to the chassis on the centerline for better balance and tweak.

The rear bulkheads feature a split design, allowing the rear suspension to be mounted to separate bulkheads while the center layshaft sits on its own, super-narrow bulkheads which are positioned maximum to the center of the chassis. The split design of the bulkheads also enables super-easy access to front and rear differentials and the middle layshaft.

Integrated Belt Tension Adjustment

As with previous XRAY cars, both front and rear bulkheads feature integrated belt-tension adjustment through the use of 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.

One of the more legendary and certainly one of the most innovative set-up features in touring car designs in the last few years is without a doubt the invention and introduction of XRAY Multi-Flex Technology™ which was brought forward into the T3 platform. This smart system allows the setting of different flex characteristics for different track conditions. This extremely effective set-up feature has been updated for the T3 platform to allow for easier flex adjustments by using the multiple positions on the top deck only. No matter whether you drive on asphalt or carpet thanks to Multi-Flex Technology™ you can set the flex – soft, soft-medium, medium-stiff, stiff – or anywhere in between to best suit your track conditions.

The middle layshaft is strategically positioned towards the center of the chassis on separate, super-narrow middle layshaft bulkheads positioned along the chassis centerline. The middle drive pulleys are positioned along side of the main spur gear and as such the drivetrain energy is transmitted from the motor through the centrally-positioned spur gear to both middle layshaft pulleys… ensuring maximum balance of the car.

The T3’11 includes standard 1.4mm front and 1.2mm rear anti-roll bars. The anti-roll bars are mounted with the included composite holders to the front and rear bulkheads, and are easily mounted to the integrated anti-roll bar mounts on the suspension arms.

For easy recognition the anti-roll bar has laser-engraved stripes (representing each thickness) for easy and instant recognition. Optional anti-roll bars are available for super-fine and precise anti-roll bar adjustment.

XRAY’s self-developed Quick Roll-Centers™ make setup quick & easy. The front and rear shock towers feature pre-set optimized roll center positions. Using the eccentric aluminum roll center holders you can easily choose one of 4 quick roll-center positions on the front and rear shock towers. Easy, smart, quick.

The T3 platform features new longer XRAY Quick Roll Center™ mounts which allow for mounting longer upper camber links, resulting in higher stability and more precise handling.
