Ideal for backyard launches or small-field use, this engine delivers a dependable lift-off experience for smaller, beginner rockets. Each pack includes four motors, four igniters, and four starter plugs, ready for multiple launches right out of the box. Offering a total impulse of 1.25 N‑s, peak thrust of approximately 8.3 N (1.9 lb), and a short thrust duration of 0.30 s, the 1\/2A3‑2T provides a quick and spirited liftoff without overtaxing lightweight models. Following burnout, a 2-second delay gives your rocket time to coast to apogee before deploying its recovery system, minimizing stress on both rocket and engine. Compact yet powerful, this 13 mm engine measures 1.75″ in length, weighs just 0.23 oz (6.5 g), and contains 0.07 o\u003c\/p\u003e\u003ch3\u003eProduct details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 10011\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeartland item number:\u003c\/strong\u003e EST10011\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":53046642180408,"sku":"EST10011","price":13.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0021\/6049\/2625\/files\/010011-1-2-A3-2T-Bag.png?v=1790553156","url":"https:\/\/munclemikes.com\/es\/products\/estes-1-2a3-2t-engines-10011","provider":"Muncle Mikes","version":"1.0","type":"link"}
