Xray have introduced the 2017 version of their highly successful T4 touring car platform. 86mm wide and cut from high-quality 2.2mm carbon fibre the chassis features pre-drilled mounting positions for the new chassis backbone, optional balance weights, a graphite motor guard and adjustable battery mounts. It also sports mirrored motor cut outs for the ultimate in symmetry.

Since the release of the first XRAY touring car in 1999, XRAY has been a driving force in the 1/10 electric touring car racing scene. Continuous development and evolution of the XRAY product line has led to ever-increasing performance.

2017 features:

– All-new chassis design

– All-new inline flex adjustment

– All-new servo mount system

– All-new floating steering system

– All-new Ackermann position

– All-new graphite arms

– All-new layshaft bulkhead

– All-new motor mount bulkhead

– All-new motor mount plate

– All-new bumper

– Improved traction

– Improved steering characteristics



Class: 1/10 electric touring car

Width: adjustable 189 mm

Length: 372 mm

Wheelbase: adjustable 256-260 mm

Weight: cca 481 g

Ready-to-run weight: cca 1377 g


Chassis: CNC machined 2.2 mm laminated carbon graphite

Shock towers: machined 3.0 mm laminated carbon graphite (front + rear) with multiple shock mounting and camber link roll center positions

Body: not included, uses 190 mm type

[b]Floating Steering System.[/b]

The all-new, unique floating servo holder is now standard in the T4’17. The floating steering system is disconnected from the chassis and works fully independently without affecting flex. This makes the car easier to drive in high-traction conditions, and chassis roll is reduced especially when driving through the curbs. The car also handles better on bumpy tracks.

In combination with #302570 Steering Plate, you can adjust 4 different flex characteristics. Using the graphite steering plate, chassis flex is medium; when using the steering plate with aluminum stand, flex becomes stiffer for more aggressive handling and increased steering.

[b]Graphite Arms.[/b]

The graphite suspension arms generate more overall traction, making the car easier to drive and increasing stability. It is no surprise that they have been long-term used by factory team drivers as well as regular customers in numerous different track conditions. The new T4’17 now includes graphite suspension arms as standard parts, providing the best available performance straight out of the box.

[b]Layshaft Bulkheads.[/b]

The all-new layshaft and motor mount bulkheads are now part of the Top Deck Flex adjustment. The new bulkheads are 1mm lower which allows better flex characteristics of the car as the top deck does not touch the bulkheads if screws are not used. If the screws on the layshaft bulkheads are used, shims are inserted between the bulkheads and top deck. This new system allows flex adjustment to help set up the car for any track conditions.

There are 3 different Top Deck Flex adjustment alternatives:

[b]Motor Mount.[/b]

The T4’17 motor mount plate has an all-new design and concept.

The new motor mount plate – which is part of the motor mount – features a new extra hole for In-Line Chassis Flex adjustment. The motor mount plate is connected to the chassis via an M3 nut and an extra countersunk screw that can be placed ahead of the nut if more reinforcement is needed. Additionally, the nut can be removed and 1 of 2 holes behind the nut can be used as extra flex adjustment options.

The motor mount bulkhead is connected to the chassis by 2 screws under the layshaft and the front mounting screw is now positioned more frontwards ahead of the motor. The front mounting screw is a button-head type which is more tweak-free compared to a countersunk screw.

[b]Top Deck.[/b]

The shape of the rear portion of the top deck has been specifically designed to achieve maximum traction and in-corner steering and the shape allows for easy access to the pinion.

The top deck is machined from premium-grade 2.0mm graphite. An optional belt tensioner can be mounted to the top deck.
