Hi Flying Spice.
I had a lot of problems getting the set up right on finals - a certain amount of a good approach is getting an "eye" for the correct approach.
As you probably realise by now (11 hours) every landing is different than the previous one because of flight path, wind direction, wind speed etc.
After about 15 hours of circuit bashing I was getting frustrated with my lack of progress and changed instructors - the new instructor gave 2 pieces of very good advise:
1) Set up the final approach so that the bottom of the windscreen is along the start of the runway, varying power and speed to maintain this picture.
2) At about 10/20 feet above runway change your gaze from the runway in front of propeller to the end of the runway,
.............................works every time for me!!
