My largest ship, the Interstellar 1, requires both to get off the ground. If I added any more solids the extra weight would break the ship apart. The purpose of such a large ship is to get into space with as much extra fuel as possible. So far I've managed to get her into orbit with 5 tanks of fuel left. Better results are probably possible with this ship, but ol' Jeb had to start body-building just to handle the stick in the first few stages. Not to thread-jack too much, but what is the best way for picking up lots of speed with all this leftover fuel? An elliptical orbit with a burn of some sort at the nearest point?
