Only the first three lines concern you here, leave the others untouched.
In the example given, you need to adjust the vertical position, e.g.:
point.0= 1.000, 82.930, 0.000, -9.350, 1181.102, 0.000, 3.349, 78.000, 0.500, 2.500, 0.500, 15.000, 15.000, 0.000, 0.000, 0.000
point.1= 1.000, -3.341, -12.000, -11.383, 1574.803, 1.000, 2.188, 0.000, 1.072, 2.500, 0.498, 17.000, 17.000, 2.000, 0.000, 0.000
point.2= 1.000, -3.341, 12.000, -11.383, 1574.803, 2.000, 2.188, 0.000, 1.072, 2.500, 0.498, 17.000, 17.000, 3.000, 0.000, 0.000
These will be different for every aircraft, those figures are the distance between the defined centre-line of the aircraft and the ground. It sounds like you need to reduce the figures in your aircraft (not this example!) by a couple of feet - start there and fine tune. Re-load the aircraft after saving each change.
Only when you have that perfect, you may need to finely adjust the following:
static_pitch =
static_cg_height =
Getting this right takes patience, but the results are satisfying.
