I really like the design. That being said, I'm not having much luck with it. Everytime I try to launch the core, it all goes haywire once I start my gravity turn. I've gotten the propulsion unit into orbit, but the core does not like me. I've tried locking gimbals, throttling down, all I could think of, but once I get in to my gravity turn, I lose all control of the core. Am I missing something simple that will make me feel stupid? Or any suggestions? Thanks.
