My initial progress was slow (I was learning on a taildragger), hampered by airsickness (esp during stalling) & inability to judge flare height.
Change of instructor: the new chap got me to line up but instead of opening the throttle the following exchange took place:
'Look ahead, note where the horizon intersects the cowling.'
'Okay.'
'Memorise that image. Now, look down a bit, note how high you are above the ground.'
'Okay.'
'Memorise that image.'
'Okay.'
'Right, now fly a standard circuit and don't let the aircraft touch down till the horizon's in the right place and the height is the same as now.'
It worked. I soloed a few circuits later. The aircraft was a taildragger but the same principle applies on a trike. Just get your instructor to demo the landing attitude and then memorise it.
Stay with it! You'll get there!
