I believe we can represent that in a couple different ways:

1) As a "racial" ability
2) As a different type of Component drive limited to races with Gravitic drives or such.
3) Adding a list of ships to the VehicleSize.txt file with racial specific requirements. (I want to use this Last way to represent the Drazi Super Heavy Fighters and Vree Ultra Light Fighters.)

I guess the main root of the question is: Do we want bigger ships to need to take up more space for engines?
