"In the world of the small, agile, and super-fast 1/12 pan cars, winners are separated from the rest of the pack sometimes by only fractions of a second. With simpler designs compared to larger touring cars, attention to detail is paramount.
The new XRAY XII may at first glance seem like a simple and traditional design, but that's where the similarities end. The XRAY XII achieves a state of perfection by focusing on well thought-out refinements to create a car that is easy to drive, work on, and adjust.
Top-quality materials such as self-developed composite mixtures, HUDY Spring Steel™, premium Swiss 7075 T6 aluminum and highest-grade graphite are the signature of XRAY and the XII has them in abundance. Designed in virtual reality using the world's most sophisticated CAD tools, and manufactured using the world's best machining and molding machinery, the XII achieves a level of premium perfection in all details that is second to none. All parts are purpose-designed and manufactured by XRAY, so all parts fit and work perfectly together.
In a world where overly-complicated designs hinder rather than enhance, the XII stands alone and ahead as the best performing out-of-the-box racer.
See it. Feel it. Drive it."
- Dipl. Eng. Juraj Hudy, Chief Engineer, XRAY
XRAY XII Main Features:
All-new XII
XRAY's new XII 1:12 pan car is the logical evolution of a conventional and proven design, with authentic 100% self-developed XRAY parts, designed and manufactured parts by XRAY in Europe. Specially designed and optimized for brushless and brushed motors, the high-competition design focuses on ultra-low weight, resulting in super-lightweight construction.
When it comes to the details and perfection, XRAY sets the standard and is unbeatable. The XII is nothing less than artistic craftsmanship.
Conventional and proven 1/12 platform
Starting with a conventional yet proven 1:12 platform, legendary RC designer and XRAY's award-winning Chief Designer Ing. Hudy Juraj made simple yet smart changes to all aspects of the car... incorporating well thought-out details and unmatched precision of all small details.
Brushless optimized
The XII has a weight balance that is optimized when using brushless motors, though brushed motors are easily accommodated in the rear pod with a bit of shimming to compensate for their lighter weight.
Chassis
CNC-machined chassis is custom-manufactured from 2.0 mm high-grade graphite material with a specially-designed compound for carpet racing and asphalt racing. For extra-high grip carpet tracks, an optional stiff chassis will be available. Chassis layout is optimally designed to provide proper stiffness for excellent handling, while being flexible enough to generate best grip and traction. The super-narrow T-bar system chassis design and layout centralizes all weight along the centerline.
Narrow Chassis Design
Super-narrow chassis design and layout with all weight centralized along the centerline.
Front Chassis Protection
Composite front chassis protectors provide protection where the car needs it most... in the front corners of chassis where damage may occur from racing impacts.
Adjustable Body Posts
Robust body posts with fully-adjustable body holders; optional super fine +1 or +2 mm body backstops available optionally for even more super-fine body height adjustment.
Premium Composite Parts
All composite parts are manufactured by XRAY using premium self-developed composite mixtures which guarantee appropriate flex of the suspension parts, while being hard enough to withstand hard impacts.
