The Estes E12-4 engine is a strong-selling mid-power option that gives hobbyists the performance they’re looking for in their next launch. With a 24mm diameter and 30.00 N-sec of total impulse, this engine is ideal for customers moving up from smaller C and D engines into more advanced flights. Stocking the E12-4 ensures your shop can meet the demand for reliable, high-performance engines that appeal to both seasoned rocketeers and ambitious beginners.

Known for its consistency and quality, the E12-4 offers an exciting balance of thrust and flight control. Its 4-second delay is perfectly timed for a wide range of rockets, making it a versatile addition to your engine lineup. Customers appreciate the dependable ignition and smooth flight sequences that Estes engines are famous for, which means they’ll keep coming back to your store for more.

With a maximum lift weight of 17 ounces, this engine supports a broad selection of mid-size rockets. That versatility makes it a strong recommendation for hobby shop staff helping customers choose the right engine for their rockets. It’s also a great stepping stone for rocketeers eager to try larger engines without moving into high-power certifications, giving your store a product that bridges beginner and advanced flights.

Each E12-4 engine pack includes 2 engines, 2 starters, and 4 starter plugs, ensuring customers get everything they need for multiple launches.
