high power scratch build

So I attempted my L1 cert flight back in January, but it didn't go that well. Here's a link to my flight report thread if you're interested: https://www.rocketryforum.com/threads/tis-but-a-scratch.177191/ . But I am back in the saddle with my next rocket, the little brother to Genesis, Genesis...

So I am rebuilding my Genesis rocket to re-attempt my L.1 cert. I want to try to add a tracker to start getting familiar with the tech. I saw that the transmitter was 6.5 inches by itself, but one of the changes I'm making to the design is going with a 6 inch coupler instead of a 9 inch. I know...

Hi everyone, I just wanted to get people's opinions/tips on a "little" project that my college rocketry team is working on. Intended to test our manufacturing capabilities in hopes that the lessons learned can be applied to our much larger competition multi-stage rocket, this project is...
