It took me a while, but I made this ship hull only. No interior yet since Frontier Developments hasn't made Space Legs yet hehe.

The actual ship is 152.4 x 61.8 x 31 m in dimensions. Assuming 1 block = 1 m, then my proportions are off, oh well.
Current proportions are 160 x 63 x 34 blocks.

I actually have two versions of this; one with landing gear deployed on the ground and one without landing gear but with hardpoints deployed.
