2016 All-new Features.
- New chassis
- New aluminum 2-speed bulkheads
- New aluminum front upper clamps
- New engine mount Multi-Flex
- New front suspension Multi-Flex
- New rear suspension Multi-Flex
- New steering block aluminum extensions
The NT1 chassis has been re-designed to fit the new 2-speed layshaft rear bulkheads inside the chassis, for better and more precise placement. Extra 2 holes for new motor mounts were added for improved chassis flex.
The chassis gives improved performance in corners and provides great stability. Overall, the chassis is very narrow to increase chassis flex and generate more traction and steering. The narrow chassis also prevents chassis contact during cornering, and helps to eliminate the car ‘stopping‘ in mid-corner.
The new, lightweight chassis is CNC-machined from premium Swiss 7075 T6 aluminum and is strategically machined in low-stress areas to make it as light as possible without adversely affecting strength or rigidity.
The area under the engine features air-flow cut-outs for extra cooling airflow. The outer edges of the chassis have been beveled and screw holes have been countersunk to create a smooth lower surface.
The new 2-speed layshaft rear bulkheads were re-designed to fit inside of the chassis, for better and more precise placement. These new bulkheads are an integral part of the chassis Multi-Flex system that offers the choice of 3 different flex adjustments.
The bulkheads are CNC-machined from premium Swiss 7075 T6 aluminum to ensure the lightest & strongest support framework for the 2-speed layshaft.
Front Upper Clamps.
The front aluminum upper clamps were re-designed for improved flex adjustment of the front suspension. With the new design, the upper clamps can be connected with the aluminum upper arm holder to reinforce the front suspension and give improved steering characteristics.
The super-lightweight upper clamps have a very clean and lightweight design to create the lowest weight and CG, making the NT1 easy to service and retaining easy access to all parts.
The front upper clamps are CNC-machined from premium Swiss 7075 T6 aluminum to provide the lightest & strongest support framework for the car.
The new engine mounts are now part of the Multi-Flex system that allows chassis flex adjustment to suit particular track conditions.
Inner mounting positions – softer chassis flex, generates more traction, recommended for low-traction tracks or with use of spec tires.
Outer mounting positions – stiffer chassis flex, generates less traction, recommended for high-traction tracks or with use with tires with additive.
Rear Suspension Multi-Flex.
The all-new rear suspension design features Multi-Flex quick adjustment to easily adapt the handling of the car to particular track conditions and tires used. There are 3 different flex characteristics to choose from.
Front Suspension Multi-Flex.
Similar to the new rear suspension, the front suspension also now features the unique Multi-Flex system that allows you to easily adapt the car to particular track conditions and tires used. There are 3 different flex characteristics to choose from.
Steering Block Extensions.
The new extensions for steering blocks are made from aluminum for increased durability and unmatched lifespan. The aluminum extensions have the same well-proven geometry including the same Ackermann positions.
The extensions are CNC-machined from premium Swiss 7075 T6 aluminum, and are black anodized. The extensions mount to the steering blocks and feature 3 different Ackermann positions. Bump steer can be easily changed by adding or removing shims.
The main frame and backbone of the car consists of high-precision aluminum bulkheads and aluminum suspension holders that are mounted to the aluminum chassis.
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 with maximum flex characteristics to increase the traction.
The bulkheads are anodized in a distinctive orange color. XRAY’s legendary attention to detail is noticeable in all the precisely chamfered edges. Color may vary slightly between products.
When it comes to setting new standards in the RC industry, XRAY is always leading the pack in bringing new and innovative engineering ideas and solutions, raising the bar and quickly becoming a new market standard for others to follow.
XRAY’s innovative Multi-Flex Technology (MFT) was originally designed for 1/10 electric touring cars, and has resulted in some of the most significant milestones in touring car development in the past several years. This innovation not only received numerous awards and honors, but it has proven to be a distinct competitive advantage at racetracks worldwide… helping XRAY dominate races everywhere from local to national events.
The NT1 was the first nitro touring car featuring the Multi-Flex system. With the optional Multi-Flex 1-piece engine mounting system, flex can be easily adjusted for various racing conditions or to complement different driving styles.
Premium & Exclusive Materials.
The NT1 is luxury model racing car and as such features only the finest, most premium materials: premium woven graphite – exclusive top-secret HUDY Spring Steel – high grade Swiss 7075 T6 – high-tensile heat-treated steel and aircraft aluminum – and XRAY’s self-developed and formulated composite compounds. All is premium and unique on the NT1.
Low CG Platform.
Thanks to the very intelligent design concept and engineering, all parts are positioned ultra-low to create a very low CG resulting in super-stable and precise handling.
Front Multi-Flex adjustment via radio plate bushing in the servo saver area is a very useful feature. When the bushing is used, the fixed setting is activated; when the bushing is removed, the screw is directly mounted on the servo saver post and the whole front suspension has increased flex. The fixed setting is recommended when there is sufficient in-corner steering. To increase the in-corner steering, the flex setting can be easily adjusted.
The radio plate is an integral part of Multi-Flex setting, and allows for very quick & easy flex adjustment. Bushings on the back of the radio plate allow it to be attached to the mounts either rigidly or with an allowance for flex. The ‘rigidly fixed’ setting is recommended for high-traction conditions. The ‘flex’ setting is recommended for low-traction tracks to generate more traction.
The muffler mount is not attached to the radio plate any more, so that eliminates the negative influence of flex. With this design, the radio plate flexes equally to both sides which improves consistency and, as it allows more flex in the front, also provides more in-corner steering.
Fuel Tank Mounting.
The 75cc fuel tank with hypertonic tank lid and internal stone-type filter is positioned in the center of the car, and features a unique low-profile design to allow the fuel tank to sit as low as possible. The fuel tank is mounted with rummber grommets and O-ring with a special screw to reduce vibration. With extra space around the fuel tank in the radio plate, the fuel tank has greater movement in all directions which improves fuel pickup and scavenging as fuel is used up.
The fuel tank is molded from a special composite mixture which guarantees it to be extremely strong and robust. The fuel tank is glued together using a special self-developed robotic system that ensures maximum accuracy and precision in pre-heating and gluing.
The receiver battery pack is located beneath the fuel tank to help create a low CG. Using the optional micro-size receiver battery pack allows the fuel tank to be lowered by another 3mm, creating an ultra-low nitro touring platform.
The battery holder allows to fit the most common LiPo or LiFe batteries. The receiver battery pack can be easily removed from below the fuel tank by a quick access composite cover at the bottom of the chassis.
Optional graphite cover contains a special CNC-machined pocket in which to place the batteries, allowing the batteries to sit as low as possible. The main feature of the graphite cover is its integrated Multi-Flex Technology functionality to additionally reinforce the chassis in the vertical plane.
Compact lightweight radio case features a clean design and layout. The radio case is attached to the side of the radio plate and will fit any standard-size receiver and optional switch with water-resistant rubber cover.
Rear Upper Clamps.
The rear upper clamps hold the rear shock tower as well as the graphite roll-center bridge. For extra roll center adjustment, the graphite roll-center bridge can be removed and the rear linkage can be mounted directly to the upper clamps to improve cornering speed and steering in high-traction conditions.
The super-lightweight upper clamps have a very clean and lightweight design to create the lowest weight and CG, making the NT1 easy to service and retaining easy access to all parts.
The rear upper clamps are CNC-machined from premium Swiss 7075 T6 aluminum to provide the lightest & strongest support framework for the car.
The roll-center bridge features 6 roll center positions for the rear upper linkage (identical to previous versions). Machined from premium-grade 2.5mm graphite, the bridge is small and lightweight.
Rear Stiffener Link.
The rear stiffener link was designed to enhance the flex characteristics around the engine area. The link can be mounted on the right side 2-speed bulkhead and right-side composite radio plate mount. The link provides optimized flex characteristics and can be easily removed when extra steering needed. An optional graphite stiffener can be used to eliminate flex for high-traction tracks.
Machined from premium-grade 2.5mm (front) and 3.0mm (rear) graphite, the shock towers are small & lightweight. The well-proven shock mounting positions remain unchanged.
The shocks provide maximum traction and steering characteristics, and optimized up & down travel. Long shock bodies accommodate the long shock shafts, and pistons are made from special white Delrin material with optimized hole number and sizes. Shock rods have been specifically hardened to ensure long life and maximum strength.
The set of pistons include 2 and 3-hole pistons with 1.0, 1.1, and 1.2mm diameter holes. The pistons are molded using special methods from Delrin material to ensure extreme roundness, while maintaining maximum stiffness and durability.
