Xray | XB4 2020 1/10th 4WD Electric Buggy Kit – Improved Stability with Longer Chassis

///Xray | XB4 2020 1/10th 4WD Electric Buggy Kit – Improved Stability with Longer Chassis
  • rcmart-blog-cover-Xray-XB4-2020-1-10th-4WD-Electric-Buggy-Kit-Improved-Stability-with-Longer-Chassis

Xray had introduced the 2020 variant of their IFMAR World Championship winning XB4 1/10th 4WD electric buggy kit. The popular vehicle underwent some sort of a redesign for the new season with a longer chassis making for improved stability while a more narrow design in the bulkhead area allows the use of optional longer arms.

Let’s check out it now!

 The gearboxes also saw an update, making them more narrow to make way for the new narrow suspension mounts and thus updated arm positions. A rear gearbox raiser plate improved the gearbox’s position when running in high-bite track conditions and inside the bulkheads operate redesigned gear differentials with larger oil volume, resulting in more consistent performance over a run. Part of the new diff package are also separate new-module crown gears and composite diff covers for better serviceability and lower weight.

Also new in the driveline area are new module crown gears for more efficient operation as well as centre driveshafts with larger 2.5mm cross pins. New, longer front and rear outer driveshafts, an updated motor mount for easier pinion gear access as well as an all-new centre upper graphite brace and a shorter slipper assembly with a wider adjustment range round out the drivetrain package. Other features include new aluminium roll centre mounts on rear uprights with updated roll centre positions, a revised rear graphite shock tower can be mounted from both sides of the gearbox to fine-tune the shock setup weight balance, and reinforced servo saver stands make for improved steering precision while a new shape improves clearance. The kit is rounded out by an improved servo mount system to optimise steering consistency in high traction conditions. The kit has already shipped and should be available by the time you read this.
