Building on the winning heritage from the multi-champion Xti and Xti Altered Ego cars, the new CRC Xti WC is now available to order. The new CRC Xti WC “World Champion” edition features a new chassis and front sub frame (U-plate) as well as minor geometry tweaks to make this latest machine the best chassis for both modified and spec class racing. The same car Marc Rheinard drove to a dominant World Championships is now available to the public.
The new Xti-WC features a new front sub frame using 6 attachment points rather than 4. The “double decker” design coupled with the increased mounting positions results in the most rigid and stiff 1/12th chassis on the market. However, the user can remove 1 set of mounting points to adjust the front flex of the chassis adding to the flexibility of the design. Xti and Xti Altered Ego owners can easily upgrade their cars to the new WC spec.
CRC’s lower front A-arm has molded in lugs that locate the arm in the U-plate. The arm literally “snaps” into place. This firm locking method keeps the suspension straight, rigid and true through all the forces and bumping that take place in a fast paced 1/12th race. The past method of using countersunk screw heads to mount the front suspension members can lead to chassis warping and twisting after repeated encounters into the barriers. With the U-plate, a flat bottomed button head screw pulls the locating lug into the flat carbon fiber, resulting in a stiff, solid and true mounting platform. In addition, modern high performance 1/12th race cars now develop high lateral forces and use very small tire diameters to maximize grip. With the arm bolted into a sub frame that sits on the chassis, the U-plate design uses less spacing to raise the arm resulting in less flex and more consistency. Unlike other designs with tall aluminum bulkheads, the arm is mounted closer to its base plate. With the Xti WC, optional small colored mylar spacers allow the racers to adjust for tire wear and allow precision ride-height adjustment. While these adjusters cover a range of competition tire sizes, for those racers that use very large tires, optional parts are available to allow you to adjust ride height even when using larger diameter front tires.
The WC is extremely adjustable and features both inline and transverse battery positions. In the transverse orientation, the battery position is widely adjustable forward and rearward. In the “front-to-back” or inline position, the new Xti WC carries over the symmetrical battery position from the Xti. Only CRC puts the fuel tank (battery) in the center of the chassis, keeping even balance despite changes in battery weights.
Not only are all CRC products tested by top professional racers, but each week at our CRC club/test track our products are used by club racers and general hobbyists. With new inexperienced racers building and using the car, this allows the CRC staff to evaluate many facets of the product; the ease of building, understanding of the assembly manual and basic setups as well as any durability issues once the product hits the track. With this feedback, we address any issues that cause the new racers problems or confusion. After hearing some of the feedback, we beefed up the chassis in key stress points. There is extra material around the front body post holes to help relieve issues when drivers have board meetings without the bumper installed. Also material has been added around the link holes to strengthen these stressed areas.
In this day and age of big batteries with a lot of runtime, the importance of the race-ready weight of the car is sometimes forgotten or dismissed. In stock-spec style racing, lightweight equals fast lap times as It takes energy to both accelerate and turn a heavier car. The Xti-WC is the lightest competition 1/12th scale available weighing in under the weight minimum with competition electronics. As with all CRC designs, the Xti WC will get you at or near the IFMAR/ROAR weight minimums to give the performance advantage needed to win.
The new CRC Xti WC from Calandra Racing Concepts is a razor sharp weapon ready to win at any level. The design is based from CRC’s long heritage of championship winning road racing cars. Designed and built by the engineers and racing staff at CRC, your new Xti-WC is created by experienced racers from the conception of the design right through to production, packaging and support. Like all CRC products, the WC is used weekly by local racers at CRC’s test track. This insures that the parts have been proven by top professionals, weekly club racers and general hobbyists, covering all facets of the product; performance, ease of use and durability. The Xti platform is a proven winner on the biggest racing stages, winning on EVERY stage; the IFMAR World Championships, the Japanese Nationals, the European Nationals, the ROAR Nationals, the IIC in Vegas, the AOC in Japan, and the Snowbirds in Florida. The product is supported throughout North America with CRC’s extensive domestic distribution through Horizon Hobby Distributors, our vast dealer network and direct from the factory. Worldwide, CRC’s international distribution and support centers in Europe and Asia insure that parts and support is easy and convenient to obtain.
