Building a modified LOC IV kit for the goal of Level 1 certification. I’ll build this with the intent of flying conservatively, including ejection deployment of the chute. The fins on this rocket have been an area of conern for many others, so I’m also going to swap these out with my own laser-cut fins.
LOC IV rocket kit as received.
What’s in the kit:
I’ll begin by weighing each item and updating my Open Rocket simulation accordingly. The file I’m starting with was imported from a RockSim file provided by LOC Precision.
