Reviews : Estes B6-6 Model Rocket Engines (3)

I was concerned about losing some of my rockets due to field size, wind, and parachute drift. I bought and used some to experiment. The recovery ejection delay is consistent and noticeably longer. The delay is so long some of my heavier rockets seriously plummeted to earth before the parachute popped, thought they were gonners. I actually had one parachute rip due to the speed it was coming down at when the parachute came out. I recommend these for small rockets that you really want to shoot high but do not want drifting a mile away, like those that use streamer recovery.

If you want your rocket 100 feet off the ground before ejection this is the engine to get. But I tried this on one of my rockets and the rocket smashed into the ground before the ejection charge blew. Broke my fin and smashed my nosecone.

I prefer this engine for my small to mid size 2 stage rockets as i am not into pure altitude - i like to see the apogee deployment of the chute. I highly recommend these for spectator launches, everyone hets to see all the action.

Great for lightweight rockets (2 ounces). Send your rockets high with enough of an ejection delay to bring them closer to the ground for easier recovery.

Everything arrived just as expected. My grandson and I will enjoy this project, and the time spent together using it
