I don't know is it my rudder control or what (its in my stick Z and pretty hard to use), but it feels very difficult to even make clean 180-degrees turn. For some reason just slightest pull makes my A8 to "toss" it to opposite side when turning. For example, I start turning to right and woosh! the plane suddenly banks on left. I don't have many hours on this plane, but all tips are more than welcome.
