The Semroc Vega was released in 1969 as the fifth Semroc kit. Designed to be a large rocket, the Vega was inspired by the early Estes Big Bertha. Since the Vega was the fifth kit, it was named after the fifth brightest star. The Vega aslo was the forerunner to the Goliath. To cut down on inventory, the Vega was redesigned with slightly larger fins, the body tube was cut to provide a payload section and released as the Goliath. Since it was possible to build and fly the Goliath with a single engine, the Vega was only sold for one year. The Retro-Repo Vega was updated by using laser cut balsa fins and a Kevlar shock cord attachment. The original balsa nose cone and body tube were used. An engine hook was added to make engine replacement easy. A single 12″ parachute was provided.
