Xray T4 - 2013 Specs 1:10 Luxury Electric Touring Car Kit #300019

This is the XRAY T4, 2013 EU Rubber-Spec Competition 1/10 Scale Electric Touring Car Kit. For almost a full year the XRAY Research and Development team has been designing and refining the T4 chassis. In total, 5 completely different prototype chassis were made and tested all around the world on a variety of surfaces and condition during that time. Whether it was carpet or asphalt, indoor or outdoor, hot or cold conditions, thousands and thousands of laps were run and countless amounts of data was recorded, evaluated and compared.

Of those prototypes, only the best ideas and parts were chosen to be incorporated into the final prototype. This prototype was then hard-core tested for several months by XRAY team drivers all around the world. The drivers all returned with the same results, feedback and conclusion: "This is the best performing, most innovative XRAY touring car that I have ever tested or driven."

With a clear vision and mission in mind, the research team set out to accomplish five main design improvements on the T4:

  • Lowered Platform
  • Improved Chassis Flex
  • Increased Traction
  • Improved Steering Characteristics
  • Improved Weight Balance

Details:

  • Chassis: The T4 features a redesigned chassis specifically designed for all kinds of track conditions. The 2.2mm thick chassis is CNC-machined from premium-grade graphite material and provides maximum traction under low traction conditions while maintaining stability and forgiveness under high traction conditions. Weight distribution and balance characteristics have been enhanced. Due to the increase in LiPo capacity resulting in additional weight and heavier duty electronics to handle the increased power of modern brushless systems, the chassis was designed to allow the weight to move as close as possible to the chassis centerline in order to maintain balance. In addition, the bulkhead mounting holes were narrowed by 6mm to make the mounting points as narrow as possible for more traction and better balance. The front and rear portions of the chassis were strategically redesigned to provide maximum steering and traction. The chassis is an ultra-narrow 94mm wide and features pre-drilled holes for options such as: chassis weights, graphite motor guard and battery strap.

  • Top Deck: The top deck has been redesigned for the narrow bulkheads. The shape of the rear portion of the top deck has been specifically designed to achieve maximum traction and in corner steering. The top deck is machined from premium-grade 2.0mm graphite. An optional belt tensioner can be mounted to the top deck.

  • Super Low Profile (SLP) Shocks: T4 shock absorbers were completely redesigned and re-engineered. Everything is updated and the shocks are aluminum. The SLP shocks were developed to lower the CG of the car to the absolute maximum in order to improve stability. With the SLP shocks the T4 stays flatter, making it easier to drive in chicanes and more resistant to traction roll, letting you carry more speed through high traction sweepers. SLP shocks feature redesigned shock caps, shock collars, pistons, as well as all redesigned composite parts. The shocks also feature bladders and foam inserts for smoother shock operation. Shock rods have been especially hardened to ensure long life and maximum strength. Updated pistons were also designed and produced. The set of pistons include 3 and 4 hole pistons with 1.0, 1.1, and 1.2mm diameter holes. The pistons are molded using special methods and composites to ensure extreme roundness, while maintaining maximum stiffness and durability. The Super Low Profile shocks are almost 8mm shorter compared to the shocks on the T3. The shock bodies are CNC-machined from premium Swiss 7075 T6 aluminum and hardened to ensure maximum life. The shocks consist of a shortened shock body but with a larger diameter to retain the same volume of oil as the previous, longer T3 shocks.

  • Super Short Shock Springs (4S): The 4S springs have been specifically designed to complement the SLP shocks and are 5mm shorter than previous XRAY springs. The T4 comes equipped with C2.7 linear springs in the front to provide maximum stability and steering and C2.3-2.6 progressive springs in the rear to provide maximum traction and cornering speed. The main advantage and benefit of progressive springs is that as the car initially enters the corner they work like a C2.3 spring to provide maximum traction. At the same time, when the chassis begins to roll, in the middle of the corner, the spring rate progressively increases until it works like a C2.6 which allows the car to maintain maximum cornering speed. The 4S springs, like all the other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.

  • Shock Tower: To maximize the effect of the SLP shocks, both front and rear shock towers were completely redesigned and lowered by 15mm to help move the CG as low as possible. Machined from premium-grade 3.0mm graphite, the shock towers are smaller, lighter, more compact and after vigorous testing, have been race-tuned to increase on-power steering.

  • Aluminum Bulkheads: To accommodate the ultra-low design of the T4 platform with centralized weight placement, all the bulkheads were completely redesigned. These small and light bulkheads are positioned more to the chassis centerline to provide maximum traction, steering and balance. All bulkhead parts are CNC-machined from premium Swiss 7075 T6 aluminum and have been designed to provide the lightest and strongest possible support framework for the car. All 4 differential bulkheads now share a common design in order to reduce spare parts requirements and increase parts compatibility. The left and right layshaft bulkheads also share a common design and are interchangeable with one another. 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.

  • Motor Mount: The redesigned motor mount has been isolated from the layshaft bulkhead in order to eliminate unwanted tweak. The motor mount is fixed to the bulkhead by two screws and to the chassis via M3 nut providing the tweak free platform. Thanks to this unique design the motor mount has been moved 3mm closer to the chassis centerline, which increases stability and improve balance of the car. The motor mount is CNC-machined from premium Swiss 7075 T6 aluminum.

  • Upper Bulkhead Clamps: To coincide with the super narrow bulkheads, the upper bulkhead clamps were also redesigned. With 3 different roll center mounting positions, adjusting the roll center of the chassis is quick and easy. The clamp height has been reduced by 2mm compared to the previous platform, which adds additional flexibility for roll center adjustments by allowing you to add or remove shims under the ball studs. In order to keep the same well-proven roll center geometry the roll center positions have been moved outside to offset the narrow bulkhead design.

  • Suspension Mounts: The front and rear suspension holders are CNC-machined from premium Swiss 7075 T6 and are fully independent from the bulkheads and mounted directly to the chassis which increases traction and makes the car easier to drive. The front one piece holder has been updated to allow easier access to the steering rack to simplify Ackermann adjustment. The reinforced rear aluminum lower suspension holders are mounted to the chassis with two screws for extra strength and have been moved 0.75mm inboard to narrow the rear track width and provide more in corner steering.

  • Central Servo Mount: XRAY's own invented and designed central servo mount is now a standard in the T4. This style mount allows the servo to be mounted to the chassis without the servo coming into contact with the chassis plate. This design has been engineered to eliminate tweak and increase overall traction. The Swiss 7075 T6 main aluminum stand is positioned along the chassis centerline for perfectly balanced flex characteristics and holds the high-grade graphite servo plate suspended above the chassis.

  • Anti-Roll Bars: To accommodate the narrowed front and rear bulkheads, updated anti-roll bars were designed. Front 1.4mm and rear 1.2mm anti-roll bars are included in the kit, and a full line of optional anti-roll bars for super-fine tuning is available. For easy recognition the anti-roll bars have laser-engraved stripes (to indicate bar thickness) for easy and instant recognition. The anti-roll bars are mounted using the included composite holders on the front and rear bulkheads, and to the integrated anti-roll bar mounts on the suspension arms. The rear anti-roll bar mounting location was updated on the T4 and is now in a horizontal position for easier accessibility.

  • Rear Uprights: To improve the stability of the car and to increase cornering speed of the T4 the hard "H" rear uprights are included. The rear uprights feature 0° toe to ensure stability and prevent suspension geometry changes in hard crashes. There are two different roll center positions on the rear uprights, and more roll center positions can be easily adjusted by adding shims between the upright and the turnbuckle ball joint. The rear uprights feature small but robust 5x10x4mm ball-bearings to minimize un-sprung weight. The rear uprights are available in two different material formulations that were specifically blended for particular racing conditions. Also available in medium "M" hardness as an option. 1-hole uprights were developed as an optional fine-tuning part to compliment the standard 2-hole uprights for high-traction tracks where more roll of the car is desired. These 1-hole uprights provide an additional option versus the standard 2-hole upright when the outer hole does not allow enough roll, and the inner hole creates too much roll.

  • XRAY Gear Differential: The T4 gear differential increases on-power steering which is needed on nearly all types of tracks, and is ideal for both carpet and asphalt tracks. The gear differential includes a composite case and cover with pulley. Differential gears are made from tough composite material, precision-molded composite gears combined with light aluminum drive shafts, which create a lighter and super-smooth gear differential. Another key advantage of the gear differential is that it is maintenance-free. When the differential is correctly built, there is no need for maintenance for a very long time… no need for frequent oil changes, and no leakage due to the superior sealing system.

  • Suspension Holders: The T4 uses the same smart suspension holders as the T3 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 T4 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.
