Estes 1/4A3-3T Engines #10010 is an Estes model rocket engine for powered model-rocket flight and launch-day use.

The Estes 1/4A3-3T engine is a compact single stage engine designed specifically for lightweight model rockets. This 4 pack gives hobbyists a convenient bundle that includes everything needed to power four quick flights, including engines, starters, and starter plugs, all in one purchase. What makes these mini engines great is their consistency. The 1/4A3-3T is engineered to produce steady, repeatable thrust so each flight behaves the way you expect. That reliability is ideal for new flyers learning the basics, for group events where predictable performance matters, and for experienced builders who want a small engine with dependable results. Despite its small size, this engine delivers real performance with a total impulse of 0.625 N-sec and a 3 second delay for reliable deployment timing. The short burn and low weight make it perfect for delicate airframes and foam or balsa builds wher
