The Estes E16-8 is a 29 mm model rocket engine designed for larger single-stage rockets and compatible upper-stage applications. Its sustained thrust and eight-second delay make it well suited for rockets weighing up to 14.0 ounces or 396 grams that benefit from an extended coast period before recovery system deployment.

Each package includes two E16-8 engines, two starters, and four starter plugs, providing the essential ignition components needed for multiple launches with compatible model rocket equipment.

The E16-8 delivers a total impulse of 33.68 N-sec with a maximum thrust of 26.44 Newtons or 5.9 pounds. Its thrust duration is approximately 2.09 seconds, followed by an eight-second delay before ejection. This combination provides a strong boost and long coast time for compatible rockets designed for higher-altitude flight profiles.

Each engine measures approximately 4.5 inches or 11.4 centimeters long and has a 29 mm diameter. The engine weighs approximately 2.99 ounces or 84.8 grams and contains approximately 1.41 ounces or 40.0 grams of propellant.

The E16-8 is a practical choice for compatible larger rockets and suitable upper-stage applications that require a longer delay before recovery deployment. Its performance characteristics make it suitable for experienced hobbyists pursuing high-altitude flights and advanced model rocket projects. Always verify the rocket manufacturer's recommended engine configuration before use.
