Why is it that on most planes i have seen , and i am not saying by any means i have seen them all , is the vertical stabalizer and rudder set up so that when it is operated , as well as giving side to side thrust . it also gives a degree of down thrust due to the pivot angle . which has the effect of bringing the tail up and the nose down , is it not possible to get rid of the angle on the rudder so that the aircraft will in effect spin on a flat plane , if i wanted to bring the nose up or down i would use the elevator , or am i missing something . i never fly with rudder anyway , only ailerons and elevator , thats how i was taught since day one , the rudder ripped of my plane once in mid flight due to bad hinges and was just flapping by the control link but it made no difference to me.... anyway , why are rudders set up this way ...
