Freighters and engines
I think I know the answer to this but is there any ongoing benefit to building freighters with faster engines? Faster than hyper/ion drive (1 pc/wk)? I realize faster freighters could get you to the initial destination quicker for establishing the trade route (the only benefit I can think of) but after that it is always 1 pc/wk, right? Faster freighters won't be able to outrun attackers or anything like that?
