I think the more bottom rudder you give in a turn, the more the

The rudder is intended to control adverse yaw, not to turn the
airplane. Banking the airplane turns it. Some airplanes, the "idiot-
proof" ones, sometimes need no rudder at all in a turn.

Actually, I beg to differ. Banking rotates the airplane about its
longitudinal axis. Yawing rotates about its vertical axis. Neither of
these causes the airplane to change heading. It is the aerodynamic
forces that streamlines the airplane with the relative wind is what
makes it turn (ie weather vaning).

For comparison, think of the space shuttle banking or yawing in orbit.
This does not change its heading because there is no streamlining
effect.





Also because there's no lift under the wings!

You can happily do a flat turn in a lot of airplanes. Wings level and
stomp on the rudder and around it will come. Some will even do it faster
with the outboard wing down a bit. I sued to do this in supercubs and
citabrias when towing so's i could enter the pattern at some insane
speed on base and then scrub it off base to final
