Obviously, when I use my rudder it turns.
Not that obvious. Why does it turn? Because the motion of the rudder causes the plane to yaw, which in turn makes it bank (because the wings have dihedral), and then the lift makes the -plane turn. You'd get a really weird turn using just rudder if you didn't have dihedral.
''Stick and Rudder'' is indeed a terrific book.
Roger bof'em!
This one flies real funny!
