My issue keeping me ground... ME! It is definitely not the kite. So I have the basic hover, up/down and left/right. I can reverse fly the kite and land. And I can launch from both orientations. AND... I can manage my lines! I just haven't mastered the nose down orientation. I either panic and drive the kite into the ground or I actually get it stopped and then drive it into the ground. What's happening is this... When the kite stops and then starts to rise, I over control the kite to stop the motion up and end up driving it into the ground. Just lacking practice... I also noticed that when I rotate the kite to a nose down orientation, I actually rotate my hands with the kite. Yeah! Anyway, its really hard to apply the brakes when your hands are rotated. So to combat that, I try to keep my elbows in my side or gut. Its odd....never did that with my 2 line kites.
Note the orientation of my hands in the photo... bad form!
