| Chassis |
|
The NT1 chassis has been completetely redesigned to work with the new aluminum suspension flex system. The area under the rear suspension is stiffer for improved stability. The aluminum rear-front 1-piece suspension holder is inserted into the chassis for better centering. The cutouts under the arm area allows the use of the lower roll-center position without arm modification.
The chassis is 2mm longer to allow adjustment of the rear wheelbase, which allows the arms to be moved rearward for improved traction.
The new 2-speed layshaft rear bulkheads fit inside the chassis for better and more precise placement and alignment. An extra third attachment point on the layshaft rear bulkheds allows even greater reinforcement of the layshaft area.

The new chassis has a larger opening under the front suspension area for better forward traction and improved steering characteristics.
The engine area of the chassis has been redesigned as well. The matching opening for the flywheel opening has been added to the other side of the chassis for equal flex. Unneeded cooling cutouts under the engine area has been removed, giving better reinforcement in the engine area.
The redesigned chassis offer improved performance in corners and provides superior stability. The chassis is 2mm narrower overall to increase chassis flex and generate more traction and steering. The narrower chassis also prevents chassis contact during cornering, and helps to eliminate the car â stoppingâ in mid-corner.

| Aluminum Backbone. |
|
The main backbone of the car consists of high-precision, high-strenghth aluminum bulkheads and aluminum suspension holders 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. XRAYâ™s legendary attention to detail is noticeable in all the precisely chamfered edges. (Color may vary slightly between products.)

|
| 2-Speed Bulkheads |
|
The new 2-speed layshaft rear bulkheads were redesigned to fit inside of the chassis for better and more precise placement. The bulkheads have an extra mounting position ⓠ3 screws instead of 2 ⓠfor even greater reinforcement of the rear layshaft area and improved on-power stability. The new bulkheads are an integral part of the chassis Multi-Flex™ system that offers the choice of different flex adjustments.
The new 2-speed layshaft rear bulkheads allow lower mounting of the 2-speed shaft to decrease the CG of the rotating parts.

| Radio Plate |
|
A new radio plate design allows mounting of the plate on the new equidistant, aligned aluminum radio plate mounts for more equal chassis flex characteristics.
The front part of the radio plate was redesigned for improved in-corner steering, as well as improved flex of the front suspension for better forward traction.
Front Multi-Flex™ adjustment via the radio plate bushing in the servo saver area is a very useful feature. When the bushing is installed, 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.

| Rear Suspension Multi-Flex™. |
|
The 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 2 different flex characteristics to choose from:
⢠SOFT ⓠGraphite brace is not used. This allows flex in the rear suspension and generates more rear traction. Recommended for low traction tracks, or races with spec hard or large tires.
⢠STIFF - Graphite brace is connected to the 2-speed bulkheads. This setting reduces flex in the rear suspension and improves out-of-corner steering and rotation, but also slightly decreases rear traction. Recommended for medium-high-traction tracks, or when tires with additive are used.

| Rear Graphite Stiffener |
|
The redesigned rear stiffener made from 2mm graphite material works with the new aluminum radio plate mounts. The graphite stiffener replaces the previous link for increased stability.
The rear graphite stiffener was designed to enhance the flex characteristics around the engine area. The brace is mounted on the right side between the 2-speed bulkhead and the adjacent aluminum radio plate mount. The graphite stiffener provides optimized flex characteristics and can be easily removed when extra steering needed. An optional rear stiffener link is available to offer an in-between stiffness setting.

| Suspension Arms |
|
New front upper arms are made from softer material for improved in-corner steering and better forward traction.
The NT1 suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry of suspension points and materials used⦠these are all the concepts and details that had to be thoroughly reviewed to create optimal suspension arms.
The exclusive composite mixture used for suspension arms is a perfect balance between reliability and performance. The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough to provide extreme durability.
