No, I didn't adjust servo's at all. I will look to see how to do that.
Thanks for your help.
I should have mentioned that very little yaw trim adjustment is needed to keep the nose heading. I rarely need more than 1 or 2 clicks either direction, depending on battery level.
Also, when I spin right, even slowly, it looks like it is wanting to slide backwards too, so the spin looks like a large orbiting pirouette with the tail falling towards the inside. If I try to even this movement out, it will stop yawing right altogether. Something seems wrong, just not sure what. Sometimes, the thing will yaw right properly or eventually speed up. Weird.
