X-tra value = the Tandem-X two Rocket Launch Set. The Amazon is huge yet it’s from our beginner skill level! The Crossfire ISX soars to 1150 feet and both launch on standard Estes engines, and is a bit tougher to build!
LAUNCH SYSTEM INCLUDED.
Two is better than one! This exceptional rocket set features a pair of extreme, high performance rockets and a launch system.
The beginner level Amazon is as imposing as the name sounds. This giant stands almost 30 inches tall and is quick and easy to build! A black body tube, precolored plastic nose cone and fins and a tiger striped self-stick decals make building this rocket easy to do in about an hour. When flown on our standard engines, this huge rocket can reach heights over 650 feet.
The Crossfire ISX is an intermediate level kit that can easily be built in about a day. This rocket features a totally streamlined shape with aerodynamic fins and nose cone. It stands 15.6 inches tall. When launched with powerful Estes standard engines, this bullet can reach cloud busting heights up 1,150 feet. A preassembled 12 inch parachute returns the Crossfire back to earth to launch again and again.
LAUNCH SYSTEM includes Porta-Pad II Launch Pad and Electron Beam Launch Controller.
