After assembling the kite, you’ll see two marks on the kite bridle and an adjustable bridle slide. One of the marks will be black and the other red. Moving the bridle slide up toward the kite will shorten the bridle, allowing less wind to get under the kite. Moving the bridle slide away from the kite will lengthen the bridle, allowing more wind to get under the kite. On days with moderate to heavy wind, you should move the slide towards the kite so it will catch less wind and fly at a good height. On light-wind days, it’s important to adjust the slide down to lengthen the bridle. This will allow more wind to pick up the kite so that it flies at the desired height. You might need to make several adjustments during any given day depending on varying wind conditions.
