Xray X4 ’24

Xray has just presented its latest 1:10 Electric Touring Car, the X4’24.  With factory drivers Bruno Coelho and Alexander Hagberg officially debuting the new car at the Monaco RC Race Of Champions at Luca in Italy this weekend, the kit features new suspension arms with relocated shock positions improve lower arm flex and reduce twist under load.  Inner shock locations improve weight distribution with the shocks closer to the vehicle midline.  Lower arms use under arm anti-roll bar mounting and reduce shock height by 4.5mm for ultra-low CG while the upper arms are shaped for clearance around the new shock position while maintaining proper suspension geometry and rigidity.  The front and rear shock holders use shims to adjust shock positions in finer increments with 3 different shock holder mounting options provide chassis flex alternatives to tune responsiveness and grip while active or fixed rear shock holder configurations provide two dampening alternatives in one mount.  A simplified shock absorber installation uses a fixed set screw to secure the threaded shock mount stud and prevent movement in the mount during maintenance.  The car gets front steering plates with improved Ackermann positions integrate with the new arms and shock positions.  Rear ARS plates move the link forward for improved rotation.  An improved ECS drive shaft case uses a C-clip to secure a new aluminium sleeve that captures the coupler pins without the use of set screws for improved reliability and easy assembly.  A narrower chassis design reduces cornering drag, while additional material in the central motor area improves durability and reduces chassis fatigue.  Updated chassis layout matches the new lower arms, shock holders and motor mount attachment points, while also moving the battery holder mounting points closer to the centreline to reduce chassis width 3mm centering pins and an additional forward motor mount attachment point improve durability and expand flex adjustments to provide improved stability on high grip black carpet tracks.  Additional motor mount clearance for ESC wiring allows cleaner electronics installation.  Bulkhead anti-roll bar locations are moved lower, along with a new ARS link position on the rear bulkheads, to match the improved suspension geometry.  Rear graphite body post holder improves durability and stability, and offers 8 adjustment steps for even more precise horizontal body mount positioning.
