I Losi is not getting the reults they wanted with the JRXS so know you are seeing them trying all kinds of mods to make it better able to compete with some of the other cars out. From watching a few friends wih this car it just don't seem to hold up as well as some other cars do. Might not be true for all but in my local area they do seem to break more than the Xrays and Corally car.
