The Estes Tandem-X Launch Set is a complete set that includes two exciting model rockets; the Crossfire ISX that streaks over 1,200 feet into the sky, and the Amazon that flies over 600 feet. The Amazon is a skill level E2X model that assembles in less than an hour, requires no painting, and is almost three feet tall. The Crossfire ISX is a skill level 1 model with laser-cut fins that is easy to build and simple to finish. Each high-flying rocket launches using Estes model rocket engines (not included) and is recovered using a 12-inch parachute (Crossfire ISX) or 18-inch parachute (Amazon). Includes two rockets, complete launch system, the Rocketeer’s guide to model rocketry, and flight supplies. Assembly requires glue, plastic model cement, and paint. Also requires Estes model rocket engines, Estes igniters and plugs, and Estes recovery wadding.
