I find this to be true on most of my warbirds. A few months ago I actually started to use the rudder to coordinate my turns using an Ares Gamma 370 Pro. The Gamma tended to drag the tail when banking so Istarted using rudder and the dragging tail stopped dragging! I then bought a Parkzone Albatross D.Va. I'm glad Istarted using rudder to coordinate turns because the Albatross almost requires that you use rudder to turn her. Iwould say that learning to use rudder for takeoffs and landings is a must. It is just an added benefit for coordinating turns. Use it. Idon't like to mix though. All my rudder use is manual.
