EST1614 C6-5 Standard Engine (3)

Three 18 mm standard class rocket motors designed to provide dependable mid-power flights for model rockets weighing less than 4 ounces including engine weight. Each motor delivers a total impulse around 10 N-s and sustained thrust that launches rockets to moderate altitudes while maintaining stable flight characteristics. Built-in delay of about 5 seconds between thrust and ejection gives rockets time to coast toward apogee before deploying recovery systems such as parachutes or streamers. Pack includes complete launch hardware with igniters and plugs for multiple launches and is widely used in educational, club, and recreational rocketry when following recommended safety practices.
