More About Sullivan

The manufacturing plant and office is located in Baltimore, Maryland.  The plant is conveniently located near a major shipping port, rail, trucking routes, and the BWI airport.

How We Began

The company was founded by Matthew Sullivan in the 1940s. The company’s first products were lines, handles and connectors for control line flying. We still make many of those products today. A bricklayer by trade, “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, the company began to pioneered electric Starters, plastic fuel tanks 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.
