I have a question that is a bit random... I noticed that one of the stability derivatives was slightly off regardless of the velocity or altitude. (Zq I think) Anyway it is not much of a problem... I don't actually think that anything is wrong with my aircraft. It is extraordinarily maneuverable and stable. However, It made me wonder if configuring the control surfaces actually changes the way that longitudinal stability derivatives are calculated. I suspect the problem with my aircraft arises from the overzealous canards in the front of the aircraft. Will limiting the angle of the control surfaces change the way the stability derivatives are calculated?
