to be a true sandbox, we need to be able to make custom wheels using fuselages and such!
I think they need to refine the fuselage hitbox so when circular it can roll perfectly like the landing gear and resizeable wheels, while being able to attach mechanisms to it (For example: The Connecting and driving rods on wheels of Steam locomotives)
so we can say goodbye to trains where their wheels have to be inside of rails in railway map mods
And have realistic looking train wheels with flanges ontop of rails

And the new wheel rims are nice, but if i want to make a custom wheel rim that does roll, i think fuselages, if set to circular, should have Circular hitboxes so they again, can roll like normal wheels
