Maybe this is what the first rocket ever launched looked like! But don’t let the Stone Age looks fool you. Underneath its rocky exterior is laser cut fins, a pre-shaped nose cone, and a sleek design that enables this rock to get over 540 feet (165 m) high. The Rock-it Stone Age Flyer™ is a Skill Level 1 kit that launches on Estes C11 or D engines. And the 18 inch (46 cm) pre-assembled parachute makes sure that it doesn’t come down like a rock. The Rock-it Stone Age Flyer™ is built using glue, modeling tools and paint – all sold separately. It includes great looking & easy to apply water transfer decals. Launches with a standard Estes Porta-Pad® II Launch Pad using a 3/16” (5 mm) Maxi™ Rod – both sold separately.
