First off, let me apologize if I'm just misunderstanding something fundamental. I am on only my first game of GalCiv2, though I can't find anything about this in the wiki or forums.
I'm playing with a custom race, but I don't think I have any speed related modifications.
I have 2 of the default design "scout" ships, as well as one of my own "fast scout" ships. The default ones have no engines on them, mine has one hyperdrive plus engine.
One of my "scout" ships has a movement speed of 3, but the other has a movement speed of 2. My "fast scout" has a movement speed of 4. Wherever I build a new "scout", it has a movement speed of only 1, and the "fast scout" has a movement speed of 2.
After reading the wiki page about speed, the 1 and 2 speed seem to make sense. What I don't understand is why the earlier ships I built have higher movement speeds. I don't have any starbases, and I didn't take any racial bonuses to speed.
Can someone explain this to me, or point me to a forum post or wiki page that explains it?
