A3-6T Engines

Experience better sight lines and a calmer recovery with the Estes A3-6T mini rocket engine. This 13mm motor is tuned to deliver a short, energetic boost followed by a six second delay, so your model reaches its highest point and then pauses before the recovery system activates. The result is a cleaner, more dramatic flight that is easy to track from the ground.

What makes the A3-6T stand out is its consistency. Estes engines are manufactured and tested to provide repeatable thrust curves and predictable delay times, which means fewer surprises on launch day and more confidence when flying with friends or family. That steady performance helps new flyers learn timing and recovery and gives experienced hobbyists the reliability they need to plan flights precisely.

On the pad the A3-6T feels familiar and safe: a crisp ignition, a confident boost, and a gentle coast that showcases both altitude and stability. It is an excellent choice for lightweight rockets and small payload lofts where visibility and controlled recovery matter. Use it with many of our mini-friendly kits to get the most out of your neighborhood launches or club meetups.

Each retail pack includes four A3-6T engines and the simple accessories you need to get flying. If you want predictable, fun flights that are easy to track and recover, the A3-6T is a dependable mini motor to add to your launch bag.
