History The inaugural 1:8 IC Track World Championship was held in 1977. Early editions were primarily dominated by American & British manufacturers, reflecting the origins of competitive radio-controlled car racing.

During the late 1980s and 1990s, European drivers and manufacturers became increasingly competitive. Italian driver Lamberto Collari emerged as a dominant figure in the category, winning multiple world titles between 1989 and 2009.RC racing historical results databases.
