Whether you are a faithful follower of the goings on at NASA, such as tracking the progress of the insight Mars lander — or a diehard Roddenberry fan, boldly going wherever you go, you're sure to love this Rocket. The Explorer Aquarius is a skill level 4 kit that features a custom jig for perfect alignment assembly. Launched with an Estes d12-5 engine (not included), The Explorer Aquarius can fly higher than 700 feet! You'll want to proudly display this show piece when it's not on the launch pad, so we've included a removable plastic display engine nozzle for the complete effect. Challenge your modeling dexterity with this uniquely designed craft.
