For the OP I’ve been back in the hobby a few years now, and as mentioned previously check out Chris Michaelson’s blog. I had to get my building skills back into shape, and researched his blog extensively. I am just now working on an Estes Saturn V. I only get to a launch a couple times a year, so a major part of the hobby is building. I also realized that I’m really slow at it, several months for a build sometimes.
