So this will happen I turn on SAS after flying a super light, long distance glider plane completely straight and horizontal. The wings are slightly curved dihedral, which provides some balancing. They're also mounted above the center of mass to take advatage of additional balancing advantage from the keel effect. SAS doesn't care, it starts gently turning the rudder elevon more and more to the right. Also I chose elevons for tail wings to save mass. It shouldn't make it particularly manoeuvrable, but this is a glider so manoeuvrability should not be an issue. Either way, elevons are not a great choice for lift purposes, but I think the wing placement relative to center of mass should compensate for the lack of that. Either way, I don't think it should affect my vector in SAS. So what is going on here? What could I do to fix it?
