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.
The servo holders feature an additional hole to fit micro servos such as Sanwa SRG-HR, HS and PGS-HR, while the standard positions still accommodate the standard 1/12 servo dimensions.
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.
The long wheelbase is the same wheelbase as previous X12 cars, and is recommended for larger tracks or tracks with longer sweepers. A long wheelbase works well at low-to-medium traction tracks when more stability is desired. Also better suited to the Open Modified classes to make the car smoother and less twitchy.
The short wheelbase allows the car to rotate better in the middle of the corner to maintain cornering speed. Recommended for tight, technical tracks or tracks with numerous hairpin corners. The short wheelbase works well at medium-to-high traction tracks where a lot of steering is needed. Also better suited to the Stock and blinky classes.
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.
Gear Differential.
The optional XRAY self-designed, revolutionary, super-smooth gear diff is a direct replacement for the ball-differential.
Using the optional gear differential makes the car more stable and easier to drive, especially in high-traction conditions. The gear diff increases on-power steering which is needed on almost all types of tracks. A “must have” for every racer.
The complete gear differential set includes a composite case and cover, precision-molded internal satellite gears made from special XRAY-developed composite material, all ensuring long lifespan and super-smooth efficient operation. A super-strong hollow steel shaft ensures maximum reliability and strength.
The advantage of the gear diff is that it is maintenance-free. When the diff 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 a superior sealing system.
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.
The steering servo is located in a lay-down position for lowest CG at the chassis center, and the layout of the chassis allows the batteries to be placed either cross or inline.
Depending on battery configuration, the ESC and receiver can be placed in various positions for ideal weight transfer and balance.
