How We Began
Matthew Sullivan founded the company in the 1940s. Sullivan Products initially produced lines, handles and connectors for control line flying. Sullivan still make many of those products today. “Matty” soon achieved enough success to make model product manufacturing his sole occupation. He was very active in the business up until his death in 1980.
As Radio Control became practical, Sullivan pioneered electric Starters, plastic fuel and an improved control rod (Gold-N-Rod). Today, Sullivan is still the leading worldwide manufacturer of those product lines. The Sullivan family of products includes Harry Higley and Perfect Parts.
