Yeah, this is hellif you want to do something "more useful" than subjects in school (exept: math, physics, and foreign languages)
btw. I think i have an idea, but when i think more about it, it becomes more "difficult": our ship is 1 model with pivot in center (i guess), if we could add an 1px large ball (with its own pivot) about 2 inches under ship and make them full group... ok, that's stupid idea XD
