Starship Expansion Project (SEP) is a mod being developed by me, Kari, and our amazing team. Our project aims to bring our intepretation of the Starship vehicle by SpaceX into Kerbal Space Program. While a lot of the design choices are based on the actual vehicle sitting on Boca Chica, creative freedom is used to expand our mod even further.

- Grid Fins can cause big roll oscillations if actuating with the engines, make sure to disable them on ignition
- If you're experiencing wobbly grid fins, reduce the authority limiter (inconsistent)
- Stock staging readings reads only part of cluster thrust data. Use KER or MJ instead
