Two is better than one with this Tandem-X Launch Set! This duo features two extreme, high-performance rockets and a powerful beast of a launch system. Designed with plastic fins, the beginner rocket Amazon stands at 30 inches tall and can be built in an hour. Launching from an Estes standard model 18 mm rocket engine C6-5, this giant can reach heights over 600 ft. Crossfire ISX, on the other hand, is an Intermediate-level rocket that features a totally streamlined shape with aerodynamic fins and nose cone. At 15.6 inches tall and launched with Estes 18mm rocket engine C6-7, the Crossfire ISX reaches cloud busting heights of 1,150 feet. A 12-inch recovery parachute glides gently in mid-air and returns the Crossfire back to earth to launch again and again. Both bullets of this Estes Tandem-X Launch Set take off from the sturdy Porta-Pad II Launch Pad by push button command from the Electron Beam controller.
