I usually scuttle my frigate factory/cap ship factory once I have a good chokepoint in my possesion and place my frigate/capital structure there. But then again, I'm a noob And it definetly isn't a bad tech to get for vasari if you intend on scuttling things.

If you were playing a game without Quickstart and Faster Resources, it might give you an edge to get a couple extra frigates out or an extra lab up.  Part of the advantage is you free up a slot on the HW so you can do something like jump straight to 3 weapon labs and Illuminators as Advent, or maybe 2 Civic labs, 1 Weapon labs for Corvettes + colonization techs, etc.  -- you get the idea.  And this is assuming you don't plan on building more capships anytime soon.  It is really personal preference, but the advantage is not that big with Quickstart and Faster resources, and of course some people have strategies where they plan to build a 2nd capship relatively quickly.

You do not need to upgrade planet logistics early on when cash income is lowest

As to answer, this is the wrong question. Better question: won't you find yourself at a disadantage when you don't have an extra frigate factory when enemy is raining corvettes or other such ships down on you?

Greg gave the further reasoning: "You do not need to upgrade planet logistics early on when cash income is lowest."

So, the capital factory is scuttled to make room for other stuff, without costing you the logistics upgrade resources.

For me, I *always* scuttle the capital factory, unless I forget, as happens more often than I would like to admit. In eco slot, I want the 4 logistics slot for a civ research center. In fighting spot, I want the 4 logistics slots for a frigate factory.

If I end up surviving long enough in a competitive game to have enough resources to justify a second capital ship, then I will have enough resources for a new capital ship factory. The location of which will be closer to the front line than my capital planet.

Seen so many regulars open with 1 civ lab 1 mil lab as TEC without scuttling capital factory.
Getting stomped in less then 5 minutes because they're going civ tech and they got 1 factory because no logistic slot for 2nd. Getting stomped coz they can only field less then half of the numbers of corvettes their opponent is fielding.

Scuttle cap fac, stick to 2 factories and avoid getting civ labs untill you can do a successfull rush.

Is there a strategy for scuttling your capital planet?

I've done that a couple of times

I've accidentally killed myself in the dev.exe that way, as I had instant build times on, and apparently that means instant scuttle times too. No chance to undo it.

HEHE

Yeah me too

Sometimes I even won after that .... so I guess it has to work
