With a total impulse of 10.00 N-sec and a thrust duration of 1.85 seconds, this 18 mm engine is engineered to provide a longer, sustained push off the launch pad—making it a strong match for mid-weight rockets and high-drag designs.\u003c\/p\u003e\n\u003cp\u003eThe 3-second delay ensures timely recovery system deployment, which is especially important for rockets with a max lift weight of up to 8.0 oz. That shorter delay window minimizes coast time and helps deploy parachutes earlier in the flight arc, leading to safer, more predictable landings—perfect for designs that don't benefit from long coasts or for flying in variable wind conditions.\u003c\/p\u003e\n\u003cp\u003eEach pack contains 3 C5-3 engines, 4 starters, and 4 starter plugs, giving you everything you need to prep for multiple launches. Just add your recovery wadding, launch pad, and controller, and you’re ready for a high-thrust experience backed by Estes’ consistent engine quality and safety.\u003c\/p\u003e\n\u003cp\u003eWhether you're testing new rocket configurations or simply want tighter control over recovery timing, the C5-3 engine offers a reliable balance of power and performance. It’s a go-to choice for intermediate rocketeers looking to expand their engine lineup with something both powerful and precise.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCompatible Rockets\u003c\/strong\u003e\u003cbr\u003eSolo\u003cbr\u003eNASA SLS\u003cbr\u003eSpaceX Falcon 9\u003cbr\u003eRoto Rocket\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv data-core-is=\"block\" class=\"ecom-block ecom-core core__block elmspace ecom-935yj497y5t short-description\"\u003e\n\u003cdiv class=\"ecom-element ecom-product-single ecom-product-single__description\"\u003e\n\u003cdiv class=\"ecom-product-single__description-wrapper\"\u003e\n\u003cdiv data-show-type=\"full\" class=\"ecom-product-single__description-container\"\u003e\n\u003cdiv class=\"ecom-product-single__description--paragraph\"\u003e\n\u003cdiv class=\"ecom-html-des\"\u003e\n\u003cp\u003e\u003cstrong\u003eATTENTION:\u003c\/strong\u003e\u003cspan\u003e \u003cem\u003eEstes Industries, LLC and Echo Six LLC requires all purchasers and users of Estes® Model Rocket Engines to adhere strictly to all applicable local, state, and federal laws, regulations, and safety standards.
