The Estes E12-0 is a 24mm booster-stage rocket engine engineered for dependable, high-thrust performance in two-stage flights. With a peak thrust of 31.3 N (7.0 lbs) and a 2.6 second burn, the E12-0 supplies the surge your second-stage motor needs for clean separation and strong initial climb. Its compact 3.8 inch length and proven propellant formulation make it a favorite for modelers who want repeatable results without complicated setup.
What sets the E12-0 apart is how it balances power and practicality. This engine was designed for straightforward use by hobbyists - it pairs seamlessly with any compatible 24mm sustainer motor to create satisfying two-stage flights. The combination of predictable thrust curve and no delay (time-delay none) means you get an immediate booster impulse when you need it most, making staging timing simpler to manage and reducing the variables that can complicate multi-stage launches.
Each package contains 2 E12-0 engines, 2 igniters, and 4 igniter plugs so you have the essentials to prepare multiple launches and spare hardware for quick turnaround between flights. The E12-0's total impulse of 28.80 N-s, propellant weight of 36.9 g, and lightweight construction (2.05 oz / 58.1 g per engine) are optimized for rockets that weigh less than 16.0 oz (454 g) including engines - the ideal choice for many 24mm two-stage kits and custom builds.
Whether you're rounding out a weekend of flying with friends or dialing in staging performance for your competition model, the E12-0 is an easy, dependable way to add a true booster stage to your rockets. Always follow Estes safety guidelines and the motor instructions printed on the package - proper engine installation, launch system compatibility, and field safety practices are essential for safe, repeatable flights.
