In my grand knowledgable experience(0.8 hrs on two TIF's) I was told to lead with the rudder. The CFI I'm about to start training with went as far as showing me a 'hands off' turn, as a demonstration, where he rolled the wings with rudders secondary effect, conducted a balanced turn, then rolled out with rudder. I know this isn't the way to turn but showed the power and importance of the rudder. Also, isn't the secondary effect of the elevator to change the airspeed? Or is that not classed as 'secondary effect'
