These companies (Radioshack, Carson, HPI) are all distributors in their respective countries. Radioshack has the US covered, Carson (although something got funny with the licensing and copyrights [now called X3200]) for Europe, and HPI for Asia. However, they are all manufactured in a plant in China, most likely by a manufacturer that changes between lines. The best quality Xmods were made by a different manufacturer than the worst quality ones (hey, take this into consideration: why do you think some Xmods had body kits, some had removable windows, etc.? Manufacturer switch that went along with worse or better paint quality.)

Anyway, Xmods are Radioshack Branded so they are a "Radioshack Product" in the US. I understand the profit issues with these as I used to have the price list as well but in reality what sells the cars is our demand coupled with the selection of body styles that walk-ins will buy. Upgrades are a niche.
