I just downloaded this game so I'm brand new, but it constantly rolls to the right for me.

Thats a bug, sometimes it works sometimes, it turns that was really annoying when building the ship :(

This thing is fun. Will it work in survival? I noticed that the blueprint doesn't include the X wings?...

The problem is that the projector block only shows the largest grid of a blueprint, so that means supergrid builds are limited to their biggest part. But the Ship will work very good without the wings, because the wings does not contain any vital system. You can also make yourself a blueprint of each wing (just remove the rotors) and then put them in one of your projectors and build them. If you have a manipulator craft you can fly the wings to their correct position and dock connect the rotor heads on the wings with the rotors on the ship. If you do so good luck and BEWARE OF CLANG! I hope that helped.
