I think the flying vehicle will become useful later on. Once they introduce missions where we have to build and explore inside a nearby crater or something like recover a lost lander. From the looks of it, the flying vehicle will be handy to transport objects across different types of terrain.
Back to the topic of Building.
I have been able to build a simple base with one airlock with no problem on Mars. But When I tried a bigger one with 2 airlocks.... the pressure in side the base is around 1kpa, way too much than outside. Anyone has any ideas or have encountered the same issue?
