The Sky Twister has a brilliant black and lime-green design! Launch it over 650 feet and watch the helicopter nose cone spin its way to the ground as the body tube floats gracefully down with a parachute. The helicopter nose cone along with the vibrant design make this one heck of a rocket. Easy to build no matter what your experience level! Have this rocket on the launch pad in just hours and enjoy countless launches! Estes model rocketry is recommended for ages 10 and up with adult supervision for those under 12.
