Rear POD:Features Overview
New 2-piece rear pod concept is positioned above the one-piece chassis. The new configuration is more adjustable with improved tweak resistance. The new pod plate is used to set droop, pod angle adjustment and supports the side springs. All-new rear spring location creates more forward traction and lowers CG.
Bulkheads:
New lightweight aluminum bulkheads help lower CG as part of the new POD assembly, with the left side bulkhead adding a cooling fan mounting provision.
Rear Assembly:
The rear carbon fiber side spring brace utilizes composite inserts pressed into the plate at the hardware attachment points for easier assembly and maintenance.
Center Shock:
All-new center shock provides exceptional bump handling, low maintenance, and helps lower CG. The spring-free design significantly reduces weights and the 1-hole piston configuration ensures consistent handling over bumps.
Dampening:
All-new rear POD spring replaces the center shock spring, improving forward traction while offering increased adjustability and lower CG. A versatile soft rear spring is included in the kit.
POD Mounting System:
All-new lowered center pivot holder controls POD movement and roll center adjustment. A small diameter pivot ball allows for the lower roll center options and the new forward center pivot position provides maximum adjustability.
Lower Suspension Arm:
The carbon fiber front lower suspension arm plate is re-designed to match the new chassis and improved geometry.
Kingpins:
All-new hollow front kingpins improve lubrication of the front suspension. The kingpins are nickel coated for even smoother dampening action.
Steering Blocks:
All-new aluminum steering blocks have special factory pre-pressed Teflon inserts for minimal friction and smoother dampening. All-new Ackermann positions improve steering characteristics.
Side Braces:
All-new thinner side braces purposely designed to accommodate the new chassis profile for enhanced chassis stiffness. The narrow width saves weight and creates more space for electronics.
Side Link Mounting System:
The narrower and lighter side link stand and M2.5 screws reduce the weight. The side link stand features a 2-pin design for more rigidity and increased tweak resistance.
Snap Lock Bushings:
All-new super smart XRAY Snap Lock Bushings replace locknuts and aluminum bushings. The 14 super small bushings reduce weight and stay securely held in place after installation for easy chassis assembly and maintenance.
Battery Holder:
All-new forward battery position and backstop provide more consistent handling and improved cornering speed.
Bumper Holder:
New carbon fiber front bumper holder aligns with the new chassis shape and provides maximum protection in crashes and perfect body shell support. The IFMAR & EFRA legal size ensures maximum aero efficiency and has a perfect fit with the 3D printed bumper.
Rear Hubs:
All-new narrower and lightweight rear wheel hubs have significantly reduced rotating weight, provide more secure installation on the rear axle and improve track width adjustability.
Rear Axle:
The ultra-lightweight steel solid axle is shorter to accommodate narrower wheel hubs. The solid axle ensures exceptional drivability and throttle response. The hollow solid axle is extremely light and durable, with a steel material that minimizes flex and makes the car more predictable to drive.
3D Printed Bumper:
The 3D printed rubber bumper improves body shell support for more aerodynamic efficiency. 3D printed material doesn't fold or break and improves front grip by allowing more airflow under the body.
Side Spring Retainers:
The side spring retainers, made from a steel material, feature a precise and consistent side dampening action.
Side Brace Flex Settings:
Side Braces allow multiple flex adjustments to adjust the flex to the particular track conditions.
Front Suspension Flex Settings:
The Tweak-Free front suspension features a front brace system for a fast steering response and high cornering speed.
Rear Ride Height:
The alu bulkheads allow for very quick & easy ride height adjustment using eccentric axle holder bushings. The axle height is adjustable in 0.25mm increments over a 2.5mm range for ride height fine tuning.
Servo Holders:
The ultra-low CG servo mounting system places the servo directly on the chassis to improve the steering response, and with adjustable grooves in the chassis to place both small and micro size servos into the absolute center of the chassis
Servo Position:
Unique & innovative fully-adjustable servo mount allows easy adjustment of the servo position. The servo is attached to independent mounts that are mounted using a groove in the chassis. Depending on the size of your servo, you can easily install and adjust the servo and its position to the center of the chassis.
Front Wheelbase:
The X12 chassis features XRAY self-developed front wheelbase adjustment possibility. The chassis has two positions for front suspension mounting; the whole front suspension can be easily moved by 2mm frontwards or rearwards.
Front Ride Height:
The front suspension uses ride height adjustment shims for very quick, precise, and hassle-free ride height adjustment depending on track conditions. The set of 0.2, 0.4, and 0.6mm ride height adjustment shims are included for fine tuning.
Side Tubes:
Lateral damping side tubes provide ultra-smooth side damping, making the car easier to drive and easier to work on. The outer aluminum tube and inner Delrin tube operate ultra-smoothly.
Servo Saver:
The XRAY servo saver has become the industry-standard saver and remains unchanged and is included. Several linkage mounting positions are offered to make the steering linkage adjustment easier. The servo saver consists of 4 springs which makes the servo saver strong enough to provide the precise steering racers demand, while still being flexible enough to prevent servo damage in hard crashes. The servo saver has interchangeable bushings to fit most popular servos.
Spur Gear:
Precision-molded spur gears are made from XRAY's exclusive composite material, ensuring true running, super-quiet operation, and robustness for handling powerful motors. A range of optional spur gears for fine tuning is available.
Differentials:
XRAY offers various differential alternatives for maximum set-up adjustments for particular track conditions. The standard Solid Axle can be exchanged for optional Gear Diff which provides more neutral handling and is suggested for medium to high traction conditions. The Solid Axle can be also exchanged for optional Ball Diff which makes the car more forgiving and is suggested for low traction conditions.
Gear Differential:
The optional XRAY self-designed, revolutionary, super-smooth gear diff is a direct replacement for the ball-differential.
Body Posts:
Robust body posts with fully-adjustable body holders; optional super-fine +1 or +2mm body backstops available optionally for even more super-fine body height adjustment.
Weight Balance:
The layout of the electronics and position of individual sections of the car were designed with optimum weight distribution and balance in mind.
Pivot Balls:
High-precision, HUDY Spring Steel upper pivot balls and composite lower pivot balls ensure smooth & precise movement of the front suspension.
Fully Adjustable:
Fully adjustable front camber, caster, toe, droop, front wheelbase and Ackermann; front offset & rear track-width; bump steer; front & rear ride height; front & rear springs; rear shock damping & spring; pod damping and droop; pod weight balance; battery position; servo position and chassis tweak.- Specs
