Get your mini model rockets in the air with these popular rocket engines.

  • Engines come with igniters, plugs, and instructions
  • Compatible with: gnome, star hopper, and others
Model rocket engines use letters and numbers to describe their impulse, thrust, and ejection variables. The letter represents the total impulse, and each letter is double the one before it. 'A' engines deliver 2.5 N·s of impulse, while 'B' engines deliver 5.0 N·s, etc. The first number is the average thrust, and the second number is the time delay between powered flight and the ejection charge. A 'T' indicates a mini engine, with a diameter of 13 mm.

Thus, a 1/2A3-4T engine delivers a total impulse of 1.25 N·s, with an average thrust of 3 N. The total time of powered flight is less than 1 second. During the 4 second delay time, the rocket is a projectile traveling toward apogee. After the delay, the ejection charge engages the recovery system. In general, the higher the average thrust, the greater the acceleration of the rocket. Heavier rockets generally need more thrust.

Estes mini rocket engine packs come with igniters, plugs to hold the igniter in place, and instructions for new rocketeers. Bulk packs also include recovery wadding. Be sure to reference the Engine Chart and Impulse Graphs for detailed information about thrust, maximum lift weight, and duration.

Facts About California Proposition 65
Ward’s Science is committed to your safety and compliance with California’s Safe Drinking Water and Toxic Enforcement Act of 1986. As of August 30, 2018 the reporting requirements of this act, more commonly known as Proposition 65 changed. These changes require retailers who do business in the State of California to provide more robust and detailed labeling on items containing certain chemicals known to the State of California to be hazardous. In response, we have added new labels like the one shown below to many of our product packages and catalog descriptions. You may now see these labels on some products and packaging, even if you do not reside in the state of California. The safety and contents of our products have not changed. Our products continue to meet the highest safety standards for your classroom. For more information about California Proposition 65 and how it affects you, visit wardsci.com/prop65.
