"A3-4T"

gregvasiloff

Works most of the time. I have had a few of these CATO in the past. They are very fragile and tend to CATO if dropped before flying.

"A3-4T 'Mini' Rocket Motor, Great little motor for light weight rockets"

champfluff

Have been using these A3-4T 'Mini' series rocket motors, for decades without any complaints, for small, light weight rockets. Wish Estes would bring back the Upper Stage release for this impulse class rocket motor A3-6T, it doesn't seem logical, now that it's discontinued. 'Mini' Booster, 'Mini' Single Stage, but no real 'Mini' Upper Stage, with a long delay, that way mini rockets can reach apogee without damaging their recovery systems.

We used these motors with our ranger outpost, they worked great.

Great all-around mini-engine. A good combination of power and versatility.
