The Legend Reborn
XRAY has long been viewed as the highest-quality touring car available since it entered the RC car scene in 2000. Now with a long and distinguished history of racing achievements and groundbreaking, award-winning innovations, XRAY is proud to offer the T3 … A top-quality “no-compromise” engineering marvel designed to put you in the winners circle.

Revolution, evolution, optimization… those are the key terms that describe the T1 and T2 platforms brought in the last decade to the racing world and the new T3 carries forward all the heritage and racing pedigree to again raise the standard ever higher. XRAY Research & Development along with the Factory Team devoted themselves to extensive testing, all in the effort to bring the consumer the latest evolution: The new T3 platform.

With fast-paced rule changes in the electric touring car class, the main focus of the T3 was to design the car for brushless motors and especially for LiPo technology… to take on what the world can offer and outperform all others under any racing conditions or rules. Take your pick — asphalt, carpet, rubber or foam tires, NiMH or high-performance LiPo batteries, cutting-edge brushed or brushless motors — the T3 can handle them all and still dominate the competition in the process. No extras needed… just a desire to win.

Pure design. Pure racing. Pure adrenaline.

LiPo Ready
The new T3 was designed to work seamlessly with new technology and therefore is designed for high-performance LiPo batteries. However, NiMH batteries users need not despair as the T3 may be used with NiMH batteries as well.

XRAY Alternative Driveline Configuration™
The XRAY Alternative Driveline Configuration™ is unique design that allows you to quickly & easily flip over the front and rear differentials and transmission belt positions. This allows you to move the electronics and batteries more to the centerline or outside of the car as necessary for the different alternative configurations of electronics weight balance.

NiMH batteries are heavier than LiPo batteries and therefore should be placed more toward the car centerline with electronics placed more outward. In this case the front belt should be placed on the left side and the rear belt on the right side to allow the batteries to be placed more towards the car centerline.

LiPo batteries are lighter and therefore should be placed more toward the outside of the car with the electronics placed toward the car centerline. In this case the front belt should be placed on the right side and the rear belt on the left side, to allow the electronics to be placed more towards the car centerline.

With this smart methodology, only 30g of additional weight (depending on electronics used) is required to balance the left and right sides equally.

Drivetrain
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 — with all types of batteries used for racing. As such the T3 comes with 38T diff pulleys and large 20T center layshaft pulleys.

The drivetrain features optimized diffs specifically used for foam and rubber spec racing. For rubber-tire racing the Front Solid Axle is used, while for foam-tire racing an adjustable ball differential is used at both front and rear.

T2 compatibility
The T3 platform is based on highly-popular T2 platform, and so the majority of spare parts and option parts are fully compatible. As such, in most cases XRAY drivers can use most of their T2 spare parts on the new T3 platform.

Ultra-lightweight Aluminum Bulkheads
The aluminum bulkheads are all new on the T3 platform. Ultra-lightweight bulkheads were designed to get better traction, steering, and balance. Bulkheads are 2mm higher to allow LiPo batteries to fit perfectly into the car. 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.

Motor Mount Bulkhead
The motor mount was redesigned to move the motor 3mm toward the car centerline for better balance, and is connected to the chassis on the centerline for better balance and tweak.

Elongated Multi-Flex Top Deck
The new elongated 1-piece top deck mount is a unique design in itself, using new composite middle shaft bearing holders to allow the top deck mount to be mounted independently from the central bulkheads. This helps to separate and elongate the flex points between the front and rear bulkheads, thus resulting in increased traction.

 Suspension Holders
The T3 uses the same smart suspension holders as the T2 platform. The aluminum inserts in the composite holders guarantee that geometry and setup will not change and will be retained even after hard crashes.

There are 3 different suspension composite holders that enable easy roll center setup. The standard suspension holder gives a 0mm roll center, while two eccentric suspension holders raise or lower the roll center by 0.75mm.

The independent suspension holders of the T3 allow for even more precise roll center adjustment. The suspension holders — which are mounted on separate bulkheads — may be shimmed outward from the bulkheads (using 0.1–0.5mm shims) for precise roll center positioning.

The smart XRAY geometry uses variable-thickness shims between the bulkheads and suspension holders to enable easy rear toe-in adjustment. However, you can easily remove the shims which will narrow the suspension, and then add wheel offset shims to reclaim track-width.

Steering Blocks
The new modified steering blocks allow for more angling which increases steering and cornering speed. The small and tough steering blocks each feature two Ackermann positions. The front steering blocks also feature small but robust 5x10 ball-bearings to minimize unsprung weight.

The steering blocks are available in two different hardness’s, which are optimized for particular racing conditions. The EU Edition includes medium hardness (M) steering blocks specially optimized for rubber-tire racing, while the US Edition includes hard hardness (H) steering blocks that are well proven to provide a solid and stiff suspension for foam-tire racing.
