A3-2T Engines

The Estes A3-2T mini engine offers reliable performance for small, lightweight model rockets commonly used in classroom and youth programs. With a total impulse of 2.50 N sec and a 2 second delay, this 13mm motor delivers a clean boost followed by a short, well timed coast before recovery deployment. The modest thrust profile makes it appropriate for entry level rockets and structured launch days where controlled altitude is important.

In educational environments, consistency matters. The A3-2T is manufactured to tight quality standards to ensure dependable ignition and repeatable flight results. This reliability supports lesson plans focused on Newton’s Laws of Motion, force and acceleration, and data collection activities such as altitude tracking and flight comparison studies.

The 2 second delay is especially effective for very light rockets, allowing students to observe the transition from powered ascent to coasting flight before recovery begins. When matched correctly to approved 13mm rocket kits, this engine helps create safe, confidence building launch experiences for students in upper elementary through middle school programs.

Each package includes four A3-2T engines, four starters, and four mini starter plugs, providing multiple launch opportunities for classroom groups or small teams. As with all model rocket motors, adult supervision and adherence to the Model Rocket Safety Code are required during storage, preparation, and launch activities.
