CRC released the "Xti' platform at the worlds event in 2012. Like many of past CRC designs, the Xti platform brought fresh, new ideas to the 1/12th car; true inline battery placement (the "i" in Xti) as well as transverse battery placement (the "t" in Xti). Also new, the Xti featured our super adjustable and convenient rear "Slider Pod" that makes setting rear ride height a breeze. Another new feature on the Xti platform was the front sub-frame known as the U-plate with reverse servo mounting option. The U-plate allows the CRC Pro-Strut front end to "key" into the sub-chassis, locking it straight and true. In addition, the double-deck design created by the U-plate adds a lot of rigidity to the front of the chassis. The new Xti-WC, uses 6 screws (bolts) to fasten the U-plate to the chassis (hence the proto name "6B - six bolt") whereas both the Xti and Xti-Altered Ego cars use 4 fastening points. The 2 new additional points are located wider, greatly stiffening the chassis. However, the car is designed to allow the user to remove those 2 fasteners, resulting in a more flexible front end when conditions warrant. The reverse servo mounting option allows for more room in the chassis for electronics and also enables the user to better balance the car.

In addition, we have added material to the chassis at the back of the new Xti-WC. The chassis now cradles the transverse mounted battery. We have also added more shock mounting positions going toward the front of the chassis. This allows the use of our optional shock extender and/or the optional extended top brace to bring more adjustments to the car. We have also added material around the front body post holes for those Xti owners that forgot to mount the front bumper and caused damage to the chassis after a hard frontal impact. (not an issue when using the CRC bumper). The Xti-WC has a series of small changes to make a a great car, even better. The while the "WC" is based off Altered Ego geometry, the new car has better performance, is more adjustable, more convenient and more durable.

The Xti-WC features multiple battery positions; inline and transverse. The transverse position features forward and rearward mounting positions. Back for stock racing, forward for faster modified motors.

We built the car with 2 mounts to "reserve" that space on the chassis in case we decided to install the optional extended top plate (3263) or the shock extender.

The man and the machine. CRC tires were found on 3 of the A-main finalists, Rheinard, Ishioka and X-ray driver Olly Jefferies.

Despite adding more material, the CRC Xti-WC remains the lightest on the market. At the Worlds event, while weighing our cars in technical inspection, we heard a number of times from the tech crew "must be a CRC car". When we asked why they said that, the crew commented on how the CRC chassis was the only car flirting with the IFMAR weight minimum of 730 grams. This all while using our stock steel screws on the bottom of the chassis and a full foam bumper.

Chassis: CRC “6B” prototype
Battery: Thunder Power G6 Pro Race 6800mAh 1S

ESC: Muchmore Fleta 1S
Radio: Sanwa M12
Servo: Sanwa SRG-HR
Body: PROTOform AMR-12
Tires: CRC Pro Cut Blue

The yet-unnamed new kit is virtually identical to CRC’s existing XTi “Altered Ego” car with two important changes. The center of the chassis is wider, which helps reduce flex, and the U-plate is now fastened to the chassis using two additional screws for a total of six - hence the working name “6B.”

Marc ran the “6B” in stock form as it will be sold to the public. In fact, the only part found on the car that won’t be included in the kit was the optional green shock spring. Marc used the kit-included 35 wt. shock oil and 10K damper oil. CRC was the first to use a chassis that could accommodate a transverse or inline battery on the same plate; Marc ran the transverse setup due to the low grip conditions.

CRC’s sliding rear pod is the only unit in its class that offers ride height adjustment without requiring any additional parts. Marc’s car was 3.5mm off the ground.

CRC’s 1/12-scale platform is the only chassis in its class on which the servo is reversed and bolted between the front suspension assemblies. Not only does the placement offer more room on the chassis but helps maintain the balance of the chassis.

Remarks – Marc Rheinard is running a prototype CRC chassis, nicknamed the 6B, because of the 6 bolts that mount the separate front plate, that holds the front geometry, to the main chassis. Also featuring a wider chassis than its predecessor the new front end system adds stiffness to the front of the car but it can also be used to adjust the car’s flex in this area through the use of less or more mounting screws. In terms of setup Marc has only made a change to softer side dampers and a stiffer centre spring to help give the car more traction. The 3-time TC World Champion is also running the new Fleta 1A speed from Muchmore but more details on that later.
