Damaged / Destroyed comps question

[Ratqueen]

Am I correct to think that destroyed components can only be repaired by Space Yards, and not by Repair Bays?

I found the following information on a SE4 web site:

"I love the emergency propulsion mixed with a repair unit. 16 pods and 2 repair units creates a scout that can travel 90 squares a turn!"

Well, that got me all confused, since there can only be one Emergency Propulsion component per vehicle, right? So, I designed 2 different Scout ships: 1 with an Emergency Component and a Repair Bay, and one with an Emergency Resupply Pod and a Repair Bay. When I used the emergency components on both ships, the Repair Bays on the ships didn't repair anything (and when I brought other Repair ships to them, they didn't fix anything either.) I had to bring a Space Yard ship to them to repair them... Does that make sense?

Also, can a ship equipped with a Repair Bay repair its own damaged components, and one with a Space Yard repair its own damaged/destroyed components?

I would appreciate if someone could clarify all that for me.

Thanks.
