This is my first forum post and my intent is to gain some wisdom from people who have been doing this way longer than I have and hopefully avoid learning some lessons the hard way. This build is my L2 rocket that I plan to fly on 19 Dec 2020 and is also a test bed for an eventually minimum diameter L3 build that I plan for next year. After losing my first L2 attempt rocket (never deployed and never found it due to not having GPS…) I wanted to build on what I learned and be sure to have GPS capability.
