from tension on the lines and leading edge of kite facing up-right,...... thumbs up, step back, lower your hands, hold the handles softer and closer together too. Relax, this is fun, breath, learn the cartwheel technique first so you can roll-over from inverted.
only four moves are possible,.. 1 both thumbs @ nose= forward (NOT up),
2 both thumbs @kite=reverse (NOT down)
3, one thumb @nose =clockwise rotation (not a left turn!)
4, other thumb @nose=counter-clockwise rotation (not right turn)
So the kite doesn't go up and down, and it can't go left or right, the controls are minor influence to major impact at the kite. Try softer,... and add in some body position movements and your feet don't have to be stationary either!
you'll love the quads because they can fly anywhere anytime any conditions,... you just gotta want it bad enough!
