This is the out of production and very hard to find Estes #2016 Explorer Aquarius Flying Model Rocket Kit. It is a concept for a galaxy class craft used in exploration of distant star systems and was last produced in 1994. The completed rocket is 23-inches (58cm) long, uses C12-3 motors (not included), and is Skill Level 4. NEW in a good condition shrink-wrapped box. The box has some creasing and buckling along the right panel from the tight shrink-wrap, and the shrink-wrap has a 2-inch tear at the top of of the front panel, but otherwise is in good condition.
