C11-7 Model Rocket Engines, (2pk)

The Estes C11-7 engine delivers a solid mid-power performance for rockets weighing less than 4 ounces. With a strong boost, long delay, and reliable ejection timing, it's ideal for modelers looking to push their flights higher without stepping up to D-class engines.

Each pack includes two 24 mm engines, two starters, and four starter plugs-offering everything you need to prep for launch and explore new altitudes with confidence.
