  • rcmart-blog-cover-Xray-New-Multi-Wheelbase-Aluminium-Chassis-For-XB4-2020

Xray had introduced new Multi Wheelbase Aluminium Chassis For XB4 2020 #361108. Machined from high-quality 2.5mm 7075-T6 aluminum and coming black anodized for surface protection the chassis allows to use two different wheelbase settings, a shorter one for increased car rotation in corners on high-grip tracks while the longer wheelbase setting, that shifts the rear bulkhead towards thew rear, increases stability in low-traction conditions. The chassis also features a strategically placed milled-out section to achieve the desired flex characteristics without harming overall stability.

Let’s check out it now!

Unique chassis with shorter and longer wheelbase integrated in one chassis. There are two different mounting positions for the center and rear diff assembly that allows choosing between a shorter and longer chassis alternative.

The shorter chassis setting makes the car to rotate better in corners and is recommended for high traction tracks.
The longer chassis setting makes the car more stable and is recommended for low traction tracks or bumpy Astro tracks.
The thicker and specially milled-out chassis was redesigned for XB4’20 to increase cornering speed and overall stability.
CNC-machined chassis made from 2.5mm high-quality Swiss 7075 T6 aluminum, strategically machined to make it as light as possible without affecting strength or rigidity and to achieve the desired flex characteristics. Black coated.
