Here are the deck plans I did for the YV-666. I don't feel like entering into the debate on 62m on Wookieepedia vs. 41m in Star Wars Gamer issue no. 7, or whether it is silhouette 4 or 5. There have been other threads in that regard already. I scaled these pics for 41m and based them on SWG#7. Enjoy.

I think it's a cool ship, I especially like this kind of variant.

Wow, that's a ton of hard points!

Yah, it's absurd in that fashion, but it does look cool.

I can see it now...the pilot is forced to take extreme evasive action to climb upward causing the engine to pitch up just as the port-side gunner fires a shot with what looks like a turbolaser battery into the hull of their own ship...do shields apply in this scenario?

Given that bi planes had timing chains on their MGs during WW1 I'm willing to bet that's not a scenario that's likely to occur.

This is still a great resource for gameplay.
