A3-2t Model Rocket Engines 4pk

The Estes A3-2T is a 13mm mini model rocket engine designed for lightweight rockets that need a reliable 2 second delay to ejection. This 4-pack provides smooth boost and consistent performance for beginner and intermediate flyers, making it ideal for backyard launches and rockets like the Mini Goblin, Star Hopper, Firestreak, and similar small models. The A3-2T delivers 2.5 N-sec total impulse with a brief 0.60 second thrust duration, lifting rockets up to 2.0 oz to modest altitudes before the timed delay deploys the recovery system at apogee.
