I must be doing something completely wrong, as I can't even get into Kerbin orbit with this.... I lift off fine, separate the SRB's, then things start to go wrong. If I dump the empty fuel tanks, I lose control and spin out. If I keep them on, I'm too heavy, and can't get high enough for orbit. Also, I can't turn 90 degs for gravity turn at any point, as I just don't have any control. Can you give some pointers on how to fly this big boy? Thanks!
