Hmm...I seem to be doing something wrong with this badboy.
Is there some thrust finangling required to keep it stable, does the RCS need to be active on the ascent?
I'm trying to fly her with a service module, EDO pod as well as an additional Operations Module. Cancelling a space station and trying to bring some stuff and 8 Kerbals home. But I can't seem to keep her stable.
The initial roll alone is extremely "wobbly" and tends to drag her off vector, which causes the SAS to go madhouse with the gimbaling. And at around 8-9k altitude, she flips on her back and out of control, even with full input to correct.
