Ork technology (teknalugy?) doesn't work in "non-Ork" ships. I'm planning on giving my crew an Ork Mekboy as opposed to a Tech-Priest Majoris, it will command a crew of fledgling engineers, possibly heretechs. I'm wondering if it would be out of line to give the ship a couple Ork Ship Upgrades, such as the Bigger Red Button and Grot Holes. Are there any hard and fast rules that constitute and "Ork ship"?
Mostly, it's just that so much of their stuff simply is because they're Orks, I often like to give them crap for being dumb as stumps, and about as accurate with a gun. Their ships aren't faster because of some amazing breakthrough they figured out in drives, but because most of them are so stupid they think a red paint job makes it go faster, and because enough Orks believe it, their gestalt psychic link makes it so. Sure, there are a few smart ones, but it's easy for me, and a bit fun, to just say "all Orks are stupid." The fact that I'm wrong fails to bother me, until their army pwns me it TTop, or if I ever play this, and an Ork kills me.
