The xxx 4 is def suited to those sweeping dirt/clay tracks, but as many have found out, its difficult to get just right on British astro and grass, the X5 was a much better refinement of the already amazing xx4, either way Losi will need to not follow the same path as the 22 by 'thinking' they have designed a car that is ready for British tracks, and actually create a new 4wd that is. If they do make a new model let's hope its as good as the xx4...takes my breath everytime I drive mine
