try the attached scenario,
some tips that might help with your final approach:
-if you have a joystick or joypad (i'm using my ps3 controller :blush

use the holdspeed
pro400specNN autopilot while landing to train your landings
-know you ship, deploying the landing gear will make you loose speed faster, don't get surprised if your nose starts dropping
-use only your elevons during landing
-be aggressive, pull up as late as you can (set trim to max to help you recover faster)
-don't panic when your alignment to the runway goes a bit out of the window, you have to be careful especially using the numpad not roll more than a few degrees
-try some acrobatics with a light DGIV (~20 tonnes) and use only elevons + trim
