slowcold submitted a new mod: Hakuri Starfighter Mark 2 - Updated for 1.3 - A small ship, for those bored of large ones Read more about this mod...
Note: I know modinfo files are no longer used. However, they don't cause problems and I did want to keep it in place to help credit the original author.
In terms of using ugrades to increase crew size and fuel capacity rather than having the max as soon as you complete the Erchius mission? That is easy enough done - I have the files already, since my species mod version does that. In terms of physically increasing the ship size on upgrades - no. It wouldn't be true to the spirit of the original ship mod (and my art ability would be overstrained!) to do so.
