I think we should not spam forum with new topic.
We can continue here, when we have working hoovercraft with stabilization I can delete all those posts, and you can then edit your first post and share blueprints (if you want).
As to that pendumum thing, I tried a lot of solutions when i tried to make space ships AI. I needed to teach AI how to stop ship where it wants, it was hard. I gave up, and cheated with linear damping.
So maybe now i am ready to tackle this stuff again.
