High Quality Content by WIKIPEDIA articles! XMODS are 1:28 scale electric radio-controlled cars. The cars' primary marketing focus is on customization, and they are available in a variety of body styles and types traditionally favored by tuners. Fall 2005 saw the introduction of a new model line dubbed "Evolution" which also features a line of trucks. The cars are distributed by RadioShack in the United States, by Hobby Products International (HPI Racing) in Japan and by Carson Modellsport in Europe. The original, generation one XMODS were released in fall, 2003, featuring semi-proportional steering and modular construction enabling parts to be swapped. Eleven body styles have been released. Hobby Products International continues to distribute the generation 1 car, though RadioShack has discontinued the line in the United States. For the U.S. models, each car comes with a mini-magazine, featuring write-ups on selected models and upgrade accessories.
