EST1503 1/2A3-2T Mini Engine HAZ

Single-use solid propellant mini rocket engines engineered for lightweight model rocket launches with consistent ignition and predictable performance. These 13 mm diameter motors deliver a modest total impulse with a short thrust phase and a timed delay before recovery deployment to support controlled ascents and safe descent profiles in beginner-level rockets. Packs include all primary ignition components for straightforward prep and flight.

• Compact 13 mm diameter motor body tailored to lightweight rocket airframes and mini kits.

• Total impulse calibrated at approximately 1.25 N-sec for balanced lift without overpowering small builds.

• Peak thrust around 8.3 N over a brief ~0.30 s thrust window fosters smooth lift-off.

• Built-in 2 s delay allows rocket to coast toward apogee before activation of recovery charge.

• Standard length near 1.75″ and lightweight construction supports predictable performance curve.

• Includes ignition starters and plugs sized for secure contact and reliable engine firing.

• NAR certification verifies consistent burn behavior and reliable flight characteristics for educational and hobby launches.
