Very easy way to go about it, and, in the long run, exactly what I plan on doing. However, in order to make sure the part only uses xenon I need to write modules for both xenon fuel and a part that uses only xenon fuel. Besides, knowing how to do these things makes way for greater possibilities; entire scientific spirit and all of that jazzimo. If I knew where the other modules were, that would make my opus dei, because that would be a simple copy, edit, paste job. I\'ll take anything at this point.
