Know Your Kite -
Adjusting Your Bridle , by:
Todd Little Almost all bridles are adjustable and should be tuned before each flight to suit the wind conditions present at the time. The movement of the line attachment (tow) point alters the angle of attack, or the way the kite presents itself in the wind.
When you move the tow point towards the top of the kite, it presents less of the face of the kite to the wind, allowing the kite to “float” on light winds. You’ll find that this adjustment lets the kite fly high overhead and, should the wind pick up a little, overfly (fly over your head into the wind!)
Moving the tow point lower, toward the bottom of the kite, will make the kite present more sail area to the wind. This will make the kite fly lower unless the wind is stronger to apply more energy to “push” the kite up. Of course this will also make the kite pull much more strongly, so watch out! Moving the point too far towards the bottom of the kite will stop the kite from leaving the ground all together.
Most modern kites have bridles made to be adjusted. Usually this is a simple ring which can be slid up and down the line and often the manufacturer marks a spot where the tow point should be in average wind conditions. But be aware that many store bought kites can have a mark on the bridle which is obviously ment to make the kite fly like a two ton dump truck and to frustrate potential kite enthusiasts. This is most often true with the less expensive sport kites – the kind found at Walmart
When testing/tuning a kite/stack I will sometimes attach a ring to ease in adjusting the tow point
Hope this helps getting the kites to fly close together
