If your kite flies backwards into the power zone or towards the ground on a regular basis, normally the back lines are too short. This can be corrected by making the back lines (flying lines) longer. Sometimes the kite becomes a back stall, if it lost the air stream. If the kite stalls, it is advices to sheet out the bar, meaning pushing the bar away from you, to depower the kite, making the front lines shorter, or the back lines longer. If sheeting out does not help, you can also pull on the front lines, preferable at the adjuster, quickly, and see if the kites does fly normal again. Be careful, since if the kite stalls and flies backwards into the power zone, it can get the air stream again quickly, and being in the center of the powerzone, it will move quickly to the wind window, creating a lot of power.
