I'm building a light probe with RCS. It's so light that the number of RCS ports has a noticeable effect on the mass listed in the vehicle assembly building. If I put lots of RCS ports on it, will it really have no impact on my delta V or my TWR? Is the mass listed in the vehicle assembly building unreliable for tiny craft with massless parts? Just to be clear, I'm using the stock "Place-Anywhere 7 Linear RCS Port". To spice this up a bit I'm attaching pics of the unfinished probe. As you can see, it has the 4-way RCS thruster blocks on it now. I think it would look better with the linear ports but I'd need more of them.
