Get this clear SC. At some stage set up a reasonable rudder trim (about 4 I think it was). Leave the trim alone after that- now your legs take over completely. Lock your heels on the floor, and hold it. Make small movements in line with thrust on final approach, but you will be holding quite a lot of rudder pressure. As you push thrust on, press rudder, and vice versa, frequently checking control wheel for horizontal. When you go around, trim elevator forward, and slowly press on rudder as thrust increases- don't slam the pedal forward- it is a balanced process and it comes on quite slow. Rotate the aeroplane. Think about LNav and AA, then what you want to retract flap to and level off altitude. Watch out for that rudder trim again- big power changes- keep watching that damn wheel.
I managed to kid people I could fly a 737 for many years with that- it works!
