Thanks for the shoutout! I'll add one more thing that Linear Motion Engines also convert *all* thrust in that axis to vectored thrust. That means that if you have adjustment thrusters or propellers pointing down and linear motion engines, everything will act like rotors. This is a big advantage because it means you can make your adjustment thrusters help with lift.
I'm actually planning on making a community guide about working with LMEs, because it's come up a couple times now. In the meantime, feel free to tech out my techs thread (here) to see other examples of LME airships, including some big ones.
