Yeah orbit was easy[Errorrrrr] *are you suggesting my genius design could be faulty in anyway? Note: The large main engine assisted by the SRB's are more than enough to achieve orbit.[Wait, I have miscalculated somehow. I think I added weight. It is no longer easy to achieve orbit!] **I did have one issue before, the struts were linked to the SRB's, so when the SRB's detached, they took the top part of the craft with it. True Kerbin engineering. I'm working on another Orbital rocket stage, come up against some stability problems, will fix them and continue!
