The Estes Cosmos Mariner is a 1:67 scale version of the sleek rocket plane from the X PRIZE Lone Star Space Access team. The Estes boost glider rocket spans over one foot in wingspan and 18 inches long and lifts off 250 feet into the air using a mighty Estes D engine. The glider returns in a gentle, soaring arc while the engine pod floats back to earth on a colorful, fully assembled 18 inch parachute. This is a Skill Level 2 kit and is built using glue, modeling tools and paint. After it's constructed and painted, simply apply the authentic decals and you have an accurate scale replica of an official Ansari X PRIZE spacecraft. Now it's your turn to Race Into Space and claim the $10 Million X PRIZE! Launches on Estes D size model rocket engines and recovers as a glider with the engine pod using 18 inch parachute.
