Let's say a helicopter wants to move forward. To do so, cyclic pitch is applied to the blades 90 degrees off which applies a torque on the blades to tilt the craft forward. Once the helicopter is tilted there is now lift upwards and lift forward. But why doesn't the helicopter just keep tilting forward, doing flips?
My first thought was that the pilot only applies the torque until they are satisfied with the tilt angle then returns to normal control. But this can't be the case since in many videos I've seen the swash plate remains tilted throughout the entirety of the movement. I can't think of another way that the helicopter could remain at the desired forward angle and not just flip repeatedly.
