are you talking about plans / blueprints for one… or something more like how to get up there to build it?
not really sure what you are asking for
for some examples you can check out the air ships at the Moebious Plaza and Aquatopia
here are 2 vids i’ve posted on my new thread that both show them / shows how to get to these locations
the air ships are fairly berried in the vids but the fist few mins of the Moebiuse Vid will show you how to get to them… and from there you can use the signs to find the ships
