Have your friend release the kite and fly it stright up until it stops and hovers. Your friend and you should be aware of the dangers of moderen kite flying. The newer kite lines can cut you or someone else very easily. Do not fly with people in the path of your kite and kite lines. Do not fly near telophole poles or electrical lines.
Hand position is very importent.
Keep your hands close together and between you and the kite, and your elbows at your side. This should place your hands at waist level and in front of you. Modern stunt kites can create a lot of pulling power. If your hands are at your head level, you loose the advantage of body weight and position. Large gusts will pull you off balance and you can lose control of your new kite.
