Then it depends on the flying model of the heli-model if you can apply negative pitch.
normally - if you have negative pitch eneabled the middel position of the stick is neutral pitch, moving it forward increases pitch positive moving the stick backwars increases pitch negative.
The "throttle" is adjusted automatically...
you can e.g. adjust the flying model that way that your heli cant do negative pitch, so moving the stick 'below' middle doesnt do anything...
