This is a little video to compare the WLToys 104001 to the 2018 version of the Xray XB4. The 104001 is a very close clone of the XRay, allowing the buyer to get the handling and adjustability of the XRay of a few years ago at a much lower price. There are, of course, quality and performance differences, but the "bones" of the WLToys car are based on a very high end machine.
Please note that while the slipper from the Xray may fit into the 104001 support, the drive cups are 11mm closer together than the 104001 spur. Meaning that you'd either need to find a way to extend the cups or use longer CVDs.
