This engine is designed for impressive altitude and high-performance launches, making it a favorite among seasoned rocketeers and hobbyists pushing the limits of what their rockets can do. With its extended 3.45-second thrust duration and robust 29 mm diameter casing, the F15-8 is ideal for rockets that need a sustained boost phase. The 8-second delay gives your rocket time to coast and stabilize after burnout, ensuring smoother deployments and potentially higher peak altitudes. It’s particularly well-suited for heavier or drag-intensive models that require a longer burn and post-thrust coasting phase before recovery activation. Made with high-quality composite propellant, the F15-8 delivers 49.61 N-sec\u003c\/p\u003e\u003ch3\u003eProduct details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 10042\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeartland item number:\u003c\/strong\u003e EST10042\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eUse only as directed by Estes and follow all package safety, age, launch-site, and supervision requirements.\u003c\/p\u003e","brand":"Estes","offers":[{"title":"Default Title","offer_id":53046643130680,"sku":"EST10042","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/6049\/2625\/files\/010042-F15-8-Model-Rocket-Engines.png?v=1790553191","url":"https:\/\/munclemikes.com\/products\/estes-f15-8-engines-29-mm-10042","provider":"Muncle Mikes","version":"1.0","type":"link"}
