r/modelrockets is a subreddit with 3k members. The most common kinds of discussions are solution requests and advice requests, and the community frequently discusses rocket, launch, model, build, and estes.
First we build them, then we fly them...then we go looking for them. I know it's around here somewhere, I saw it land!
Mostly posts of builds and launches but any on topic content and questions is welcome.
