STAR WARS SHIP QUESTION: I am helping my son build a Pine Wood Derby Car and he wants to design like a Star? - ship derby car

I'm working on my son to help build Pinewood Derby car and want it like a spaceship from Star Wars design. I'm not very handy, but can happen. What is the lightest boat on a piece of wood? The demsions up to 7 "(length) x 2-15/16" (W) x 3 1 / 16 cm (height). Ideas, help and photos would be greatly appreciated. I wish it were in a position to more color, when I've finished carving. He is 6 years and is a good painter. Thank you in advance.
