Hey, this is good or your first ship. If you look at any of mine you can see the C-5 egnine and copy or just study it. (P.S. Insted of putting credit on each save, I think its better to just make a save with all your copied materials and have a 'Credits-Page')
i don't know how to do that.
Also, engines are much more efficient when trust goes from left to right. I dont know why.
Engine produces no trust at all. Try to use C-5 based engine. It is looks cool and produces significant trust.
