HI!
I’ve got a slight issue in the flight model of my aircraft. No matter what I try, it rolls off to the right when flying in a straight path. Hell, I’ve even stripped it of its wings and it falls slightly to the right. To this point I had thought it was a weight issue, but even if I screw the center of weight to the left, it rolls right. Recently I’ve been screwing around with drag values in order to balance out the issue. Still rolls right.
search "auto roll simpleplanes" and there should be something.
P.S. I have also determined it not to be a airfoil issue.
