The Estes A8-5 Engine offers strong peak thrust and a 5 second delay, making it perfect for lightweight rockets that benefit from longer coast times before recovery deployment. It supports launch weights up to 2.0 ounces and delivers smooth, high-altitude flights.

This standard 18 mm engine fits a wide range of Estes rockets and comes in a 3-pack with igniters and plugs. A reliable choice for students, educators, and hobbyists seeking performance and control in every launch.
