How do I delete base parts?

[Quello]

I've started building a base, but my contructor isn't working even though I have a small generator and a small fuel tank with fuel in it. So I wondered if they have to all be right next to each other for the contructor to work?
I also want to expand my base wall territories. So wondered how I can delete/remove objects I've placed.
Thanks.

Is the power turned on in your base?
Press Y to toggle base power while standing anywhere inside.
Also check the top right of the constructor screen to make sure that is switched on.

The constructor etc can be anywhere in your base, that doesn't matter.

With the first part of your question already answered, let me turn to the seccond:

You can remove blocks with the Repair & Remove tool. You can learn it it the tech tree under tools. I think at level 3.

Ok cool thanks.
Now to my next problem. How do you add power to the hover craft? It's the basic model that you make via the blueprints and factory.
It seems to have an o2 storage, a cargo storage and a contructor built in. Tried putting some fuel into the cargo, that didn't work.

you need a fuel storage container, there should be two types, one for CV/BA the other for HV/SV. Put your fuel paks in there once you build one.

if i remember right, the fuel tank was on top...

Ah yeah, on the top, thanks :)
