Estes Industries was founded in 1958 in Denver, Colorado. Vern Estes developed a machine that mass-produced solid propellant model rocket engines. This invention gave people a consistent and reliable way to launch model rockets. Later, the company branched out into the mass production of balsa nose cones and adapters for model rockets. Estes began selling model rockets by mail in 1960. The company was moved in 1961 to a 77-acre tract of land on the outskirts of Penrose, Colorado. Rapid growth followed and soon Penrose became known as the “Model Rocket Capital of the World”. Estes Industries has grown to be the leading manufacturer of model rocket kits, engines and accessories in the world. COX joined the Estes family of products in 1996.
