So I'm using this on 1.4.5, installed via CKAN. On the github page explaining stability derivitives it says if Xu is ever wrong, something is broken in my game and I have it display red occasionally at low speeds, IE runway takeoff. I find it pretty hard to make a plane fly stable at all, I can get them to fly but take off they sometimes just spin out on the runway and I know they are not just plain badly designed. Is something broken in my install?
