XRAY have introduced the 2020 version of the XB8 1/8th Nitro Buggy kit that Ty Tessmann drove to set overall TQ at the 1/8 World Championship 2018 and finished in the 2nd Place position. This newhe new XB8 which incorporates the latest improvements and refinements gathered by the team, race-proven in the highest competition races around the world.
All-new chassis was refined and extended by 4mm to improve stability and handling characteristics. The longer chassis provides more wheelbase choices to maximize performance in every track condition.
The XB8 chassis fits both SOFT and HARD composite radio boxes without chassis modification.
The included HARD radio box increases chassis rigidity and handling consistency. The harder material also retains its stiffness in very high temperature conditions.
The optional SOFT radio box can increase traction as it allows more chassis flex.
The chassis is CNC-machined from 3mm high-quality Swiss 7075 T6 aluminum; strategically machined in low-stress areas and then anodized to make it as light as possible without affecting strength or rigidity.
The all-new front shock tower was redesigned to increase the set-up choices using the shock position adjustment. The new front shock tower features two rows of shock positions.
HIGHER shock mounting holes: Increased traction, recommended for low-traction and rough conditions
LOWER shock mounting holes: Increased stability, recommended for high-traction tracks
All-new longer central rear driveshaft to match the longer chassis.
CV drive shafts are now included for both the front and rear suspension to assist with increased traction and for easier maintenance and servicing. The front steering block ball-bearings are updated to accommodate the CV axles.
All XB8 drive shafts are manufactured from world-renowned HUDY Spring Steel™, resulting in some of the world‘s thinnest yet most durable drive shafts used in off-road cars. All drive shafts and outdrives are hardened with a proprietary hardening process to provide unsurpassed lifespan & reliability.
The central larger & stronger outdrives feature protective rubber boots, thick 3mm pins, and protective locking rings.
Both front and rear differentials are now identical for easier maintenance and servicing.
The Large Volume diffs feature higher capacity cases, stronger diff pins, and large internal gears with more teeth for improved differential action, consistency and overall reliability. The larger volume of the differential and the shape of the gear teeth help reduce oil overheating.
The high-torque clutch features a new lightweight flywheel. The flywheel was redesigned with reduced mass for quicker engine response and clutch engagement.
The high-torque clutch provides smooth, continuous power transfer from the engine to the driveline. With the included Hard springs, the clutch engages higher in the RPM range, resulting in more controllable power during acceleration while still maintaining good engine response and performance on jumps.
The Swiss 7075 T6 clutch shoes are small, lightweight, and designed for engagement during the entire travel of the shoe. The shoes are less sensitive to wear and results in improved lifespan.
The smaller diameter allows the flywheel to be more protected after landing large jumps, so there is a reduced chance of accidental engine stoppages.
The extra-tough flywheel nut is machined from Hudy Spring Steel™.
The clutch is equipped with hard clutch springs; optional soft and medium springs are also available.
The optional 4-shoe clutch features smaller, lighter internal parts, and the design allows for more balanced clutch bell engagement compared to a traditional 3-shoe design.
The 4-shoe design allows the use of multiple combinations of different shoe hardness and spring tensions for clutch engagement tuning, and even allows for mixed combinations of shoes and springs which gives ultra-fine engagement choices. There are 4 different hardness of shoes and 3 different hardness of springs available. Changing the clutch configuration is very easy thanks to the special assembly screws that hold the shoe and spring.
SOFT clutch setting generates the highest amount of traction and engages earliest.
MEDIUM clutch setting allows more clutch slippage and engages later.
HARD clutch setting engages latest and provides more revs to engine.
Diff Gears & Drivetrain Ratio.
To improve the acceleration of the XB8, the 48T spur gear is included in the kit.
Differential main gears are manufactured from HUDY Gear Steel on a precision manual gear machine. This material was specially formulated and developed for use in gears. All gears are hardened to provide the longest possible lifespan.
A wide range of different gears — spur gear, clutchbell, crown gear — is available for perfect set-up and tailoring to particular racing conditions.
Clutchbells are available in sizes of 12T, 13T, 14T, and 15T.
Spur gears are available in a range of 46T, 47T, and 48T.
To improve the braking efficiency and to ensure constant braking characteristics, the ultra-efficient pre-glued brake pads are now included in the XB8 kit. The center upper plate was redesigned to clear the larger 48T spur gear now included in the kit.
The XB8 features a well-proven, high-performance braking system that is strong, precise, and dependable to make slowing and stopping almost effortless. Coupled with the car’s balanced load distribution, the extraordinary control imparted by the braking system gives you complete confidence as you pitch the car into corners.
The laser-cut, precision flat-ground steel brake disk allows for fade-free braking in conjunction with the special high-grip brake pads installed on the laser-cut brake plates. The brake disk is small, slim, and very light. The precision hand-grinding allows true, wobble-free rotation. Brake inputs are transferred precisely to the brakes thanks to the rigid, high-precision machined brake cams. Both brake disk and brake pads are specially heat-treated for maximum lifespan.
The XB8 shocks were improved with updated shock bodies redesigned to fit the new composite lower shims for improved shock shaft movement.
The shock caps feature 4 bleed holes for easier building and more precise rebound control. The longer shock shafts allow more suspension travel. Multiple shock membrane choices are available to tune the suspension to a wide variety of track conditions.
Oversized big-bore shocks featuring 16.2mm I.D. shock bodies are externally threaded with an adjustable collar for quick & easy spring preload adjustment. The shock bodies are hardcoated in a titanium color and feature a 1-piece alu shock cap.
To fully comprehend the set-up possibilities of the XB8, we highly recommend the HUDY Set-up Book which is loaded with over 50 pages of high-quality pictures and easy-to-understand RC car set-up explanations. The HUDY Set-up book will teach you many set-up tips & tricks to help improve your set-up skills, ultimately translating into improved racing performance with your XB8.
