Hey guys. I just installed Ferram Aerospace, and I'm not quite sure what I'm doing. I learned pretty quickly that it hates ASAS, but that a stable plane flies just fine without it. The question is, what makes a stable plane? I looked at some of the pre-made designs and saw that the CoL should be above and behind the CoM, but that alone doesn't seem to do the trick. Any and all tips are much appreciated.
