IDS does nothing for drift launch... I drift launch 75% of the time. Best way:
1) attach your leash to the pump loop on the TE
2) fly the kite on it's back holding the TE/leash, as you wish
3) you can let go of the kite and let it fly on it's back at the end of the leash
4) walk across the wind as you in wind your lines
5) once unwinded, flip the kite over on the LE, the lines are behind it in a big loop, some twisting but no loops or tangles.
6) undo your leash,hold the kite,
7) lift each side of the LE so you see the whole bridle on each side, all the way, there should be no twisting or anything, this is life and death importance.
once ready, send the kite by turning the LE downwind, the wind will keep half of the canopy down and it will push the other wingtip.. . You can help it by walking in the wind to shorten the drift.. You can pull a rear line to pull the kite so it sits deep in the window.
9) do a standard launch.
Some folks put water on the canopy but it gets blown away and sometimes the kite tilts back and shoots up. ALWAYS attach your leash so the kite will flag out if QR is activated and be ready to ditch the kite... Just in case.
