Estes-Cox History 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 USPS has classified rocket motors as hazardous materials; consequently, they must be shipped Parcel Post Ground. You need to allow a minimum of 7-10 days for delivery. In rare instances, surface delivery may take longer.
