Okay so I bought a bunch of pre-fabricated Estes parts that I'm planning on turning into a two stage rocket. I understand how to build one and what they are etc. but I was wondering how to add a recovery device to the booster stage. In the first one, a black powder charge will deploy the parachute but how would I add a feature like this in a booster stage without an ejection charge? I was planning on probably using a streamer or parachute for the booster just so I can retrieve it but was just confusing myself on how I would actually attempt it for my first time. Any help is greatly appreciated!
