Hey all, this will be my first post on TRF! I decided I wanted to go for my HPR certifications after building rockets with my school’s rocketry program this past semester. So, I bought myself a LOC 4” Black Brant X to certify L1 and L2 with. I figured going with the biggest kit I could find would allow for easy sight during recovery, room for development, and the ability to fly K’s later down the line. As a side note: I purchased my kit from Robert at Buyrocketmotors.com and had great customer service. Pricing was fair, same day shipping, and even though my kit was shipped without the motor tube (lol, still not sure why) Robert and LOC had the part shipped out the next morning. I’m hoping this will be somewhat of a build thread and somewhat of an advisory for my certification process. Happy to be here!
