Well, I could not resist. The self-launching threads inspired me to ask and to be honest, I am struggling sometimes self-landing my kite in moderate to strong winds.
Here is my technique and please "refine" where possible:
* Kite is at 11 or 1
* Pull depower trim strap (or line) all the way. Full depower kite as much as possible, but still stay hooked to it

* Lower kite along edge of wind-window to 10 or 2 and here comes the tricky bit,
* Quickly pull (or yank) centre line (left line if landing on your left, right line if landing on your right)
* Leading edge should be "dipped" down so that the wind lowers the kite quickly to parking position.
* Wing tip of kite should not touch the ground (or not directly vertical, the leading edge should be the thing that touches the ground first - ideally).
* Kite should be parked
* Progress to unhook and go from there
Yeah so the quick action bit trying to "dip the leading edge" down into the wind is the bit that I sometimes nail and other times I have to quickly let go of all lines and re-attempt self landing.
Any tips on how to refine those steps?
