Thanks for your ideas.

So does real planes. The basic of a turn is to balance the aileron and elevator to achieve a turn of required radius without loosing or gaining altitude. Most plane also tend to "push out the nose" in a (so called) un-coordinated turn. This is where the rudder comes in; By applying a little rudder into the turn, the plane will turn more "cleanly".

On my EasyStar, I have programmed a 30% mix from aileron into the rudder. That is, when I apply full aileron, the rudder moves only a little.

In real planes you often also increase the power a bit when entering the turn. This help maintain constant airspeed and - to some extend - prevents loosing altitude. Furthermore, you normally don't select a bank angle of more than 30 degrees if you are approaching or departing at low speed, as the wing lift is decreased. This prevents stalls.
