This is the XRAY RX8 1/8 On Road Competition Racing Car Kit. Born through a passion for performance and developed from a 37-year heritage of dedication to engineering ingenuity, the RX8 was crafted for one reason: to be the definitive representation of XRAY craftsmanship and sophisticated engineering. The quest for realizing this dream has involved the full range resources at XRAY’s disposal: concept & design, research & development in virtual and physical reality, as well as rigorous testing. Joining its brethren in the XRAY family, the RX8 is positioned to capture the hearts and minds of the racing world, and carry them into the Winner’s Circle.

In Depth Features:

  • Prestige, elegance, luxury: The RX8 is a sophisticated, professional, high-competition 1/8 on-road car and as such the entire design concept and materials used are fully race-oriented. The RX8 features easy access to all drivetrain parts allowing super-quick rebuilds and set-up changes, making it extremely easy to work on.
  • Lowest CG Platform: Thanks to intelligent design concept and engineering, all parts are positioned ultra-low to create the lowest-possible CG resulting in super-stable and precise handling.
  • Top Deck Flex Adjustment: Radio plate flex has a significant influence on the handling and performance of an 1/8 on-road car. The RX8 features smart and simple bushings to allow either fixed or flexible radio plate mounting.
  • XRAY Multi-Flex™ Chassis Adjustment: The smart design of the RX8 chassis allows for the mounting of additional weights or stiffeners for complete chassis adjustment. Whether you need to add weight or stiffen the front or rear, you have a choice of optional front/central/rear machined brass weights and front/central/rear graphite stiffeners. At the front of the car, both the brass weight and graphite insert can be mounted either fixed or flexible to avoid undesired stiffening effect.
  • Swiss 7075 T6 Aluminum Chassis: The lightweight chassis is CNC-machined from 5mm thick premium Swiss 7075 T6 aluminum and is strategically machined in low-stress areas to make it as light as possible without affecting strength or rigidity. All screw holes on the bottom of the chassis are countersunk, allowing for a very smooth chassis underside with no protruding screw heads. The area under the engine is solid without any openings to ensure maximum strength.
  • Radio Plate & Electronics: The radio plate is CNC-machined from 2.5mm graphite material and the design allows for the easy removal of the entire radio plate (with all electronics) for quick & easy servicing and cleaning.
  • Radio Box: The unique compact lightweight radio case features a clean design and layout. The radio case is attached to the side of the radio plate and will fit any standard-size receiver and an optional on/off switch with water-resistant rubber cover. The radio case features a smart quick-exchange port for quick & easy crystal exchange without the need to open the case. The quick-exchange port is protected and sealed with a rubber cover and when using silicone on the sides of the radio case, a complete water-resistant box is created.
  • Fuel Tank: The 125cc fuel tank with hypertonic tank lid and internal stone-type filter is positioned in the center of the car, and features a unique low-profile design to allow the fuel tank to sit as low as possible. Rubber mounting grommets help to reduce vibration. The special composite mixture used in the molded tank guarantees it to be extremely strong and robust. Gluing of the tank pieces is performed by a special self-developed robotic system that ensures maximum accuracy and precision in pre-heating and gluing.
