I modified the .cfg files for the storage containers so they hold more rocket parts, so i didnt have to have as many containers. However it made my ship weigh so much that i cant get it off the ground. So i was wondering if anybody knows how to change the mass of the adjustable "rocket parts", not the container, so that when i fill the container, it doesnt weigh so much. I have looked and looked, but i have yet to find out how.
