It does work. You just have to find said loops

This does not work in more recent versions. There's no loop to make this on the grid.

What about this one, floating with no propellers?

I have 0 hex grids in view, they're all pentagons with a few octagons and one that creates a dodecagonal tile, how do you find hex grids

This is one with multiple sooooo, here ya go you can use it if your struggling

I used this but for some reason it didn't work, also my grid never has a hexagon or circle, only forms six pointed stars and triangles, is there something wrong with my grid?

Nice guide to begin. Although, it is worth noting that you do not need a perfect circle of hexagon to build a flying city. You just need to build a city "without support", which can be esily done by making a "line" flying city, and continue the lines until it circle on itself, and every support is gone.
It may take a while and result in a pretty big island, but it's kinda cool once it works :
