Here are a few ships to help get you started:
canon fodder
a small ship with a big cannon! (actually it's a regular cannon, just ignore that, it's a ship all the same!)
HI MUM!
A light-weight ship with lot's of agility! enjoy having it dodge your every bullet (or laser, or anything that does damage...)
Micro-falcon
this ship was designed for a micro-star wars ship post, and It looks very simaler to the real thing!
absolutely minimum sized ship design
I kid you not, this is probably the smallest ship that can still function. it is a bare minimum, and aside from removing a thruster, there is little you can do to make it any smaller!
basic ship
a good starting point is this ship. it functions correctly, and has crew to spare! might need a bit of shuffling to get it to maximum efficiency, but you get the general idea.
BIG GUN!
a not so little ship, with a BIG gun (this time im serious, it has a big gun!)
