Its actually a benefit not a hinderance to have to use rudder to turn. It's what makes a helicopter a helicopter and not a airplane. Its what allows you to fly sideways and backwards. If the tail followed around all the time, it would just be a airplane with a rotory wing.

Learn "Rudder"

Its an important part of flying...and if you also fly airplanes....you find your airplane flying gets better too, not to mention you have to know how to use rudder to do 3D flying. Its not just something nice to learn....its a necessity.

The best practice is figure 8's. Fly them slowly and tightly, fly them fast and large...mix it up. The more you practice these the better you will get. Figure 8's have everything needed for learning helicopters. Right and left hand turns, nose in, and forward flight. Practice flying them slowly, maintain altitude, and keep the speed at a constant speed.
