I am playing career mode, so don't have access to much yet. I am trying to make a mun lander (made several in sandbox) but they always seem to veer off-course during launch, usually uncontrollable by around 30km. I have SAS on but no modules (not unlocked) & some winglets on the sides, but it is still impossible to control. Everything was built in symmetry mode, & it is not the same direction each time, it will just start tilting off somewhere, every launch for the last 30+ attempts I have made. Anyone know why?
