I have not found any really good alternate bodies for the xo-1. the only ones that are remotely close from my research is the FG modelsport touring car they are a 400mm wheelbase and right at 300mm wide they consider them 1/5 scale though. Now I am not 100% on this it may be from an older model, but they still offer parts for the older models. Some of you have suggested the 1/7 ofna body has anyone actually tried this body yet? I found the specs for it and it seems to be short wheelbase on it is 365mm and width is 290mm from what I have found. Does anyone else have any other suggestions or first hand knowledge of what fits with some or little or no modification?
