E12-6 Standard Engines for Model Rockets (3) (EST10030)

The Estes E12-6 is a high-thrust 24 mm model rocket engine designed for mid- to large-sized rockets that require strong acceleration and a longer coast period before recovery deployment. Its six-second delay makes it well suited for heavier, efficient models that continue climbing after engine burnout.

Each package includes two E12-6 engines, two starters, and four starter plugs. This provides the essential engine and ignition components needed for two launches with compatible model rocket equipment.

The E12-6 delivers a total impulse of 29.50 N-sec with a maximum thrust of 29.60 Newtons or 6.7 pounds. Its thrust duration is approximately 2.70 seconds, followed by a six-second delay before ejection. The engine is rated for rockets with a maximum lift weight of 14.0 ounces or 397 grams.

Each engine measures approximately 3.8 inches or 9.7 centimeters long and has a 24 mm diameter. The engine weighs approximately 2.23 ounces or 63.2 grams and contains approximately 1.3 ounces or 36.9 grams of propellant.

The E12-6 is a practical choice for experienced rocketeers flying compatible mid- to large-sized models that benefit from strong thrust and an extended coast time. Its performance characteristics make it suitable for higher-altitude flights and larger rocket designs, including compatible advanced models. Always verify the rocket manufacturer's recommended engine configuration before use.
