The model was the Centuri $KB-2 with a price of $1.50 and was sold from 1962 through 1964. In 1965, the Arcon was changed to a 1/6 sca;e ,pde; based pm tje ST-10 body tube and was released as Centuri #KC-1 at a price of $2.25. This kit is based on the later version. In 1971, the balsa nose cone was changed to plastic and the same year the Arcon was discontinued. The Arcon was a popular entry level semi scale model. The Arcon is updated with precision laser cut fins. The dimensions of the KC-1 version are maintained with a balsa nose cone. The original rubber shock cord is replaced with an elastic cord for longer life. The original method of attaching the shock cord has been replaced by a Kevlar cord for greater reliability. An engine hook is also added for ease of changing the engine.
