Ready for a few tips about adjustment of the towing point? Some might call it the tow point. This is where the flying line attaches to the kite's bridle. All single line kites, whether shop-bought or home-made, have one or more lines, keels or a combination of these which are attached directly to the kite.
However simple or complex, there's just one point where the flying line attaches. In most cases, you can slide or otherwise adjust this point towards the nose or the tail of the kite.
A sliding knot can be used, but you might have noticed that some retail kites use a
small ring or clip for the same purpose. If you're buying a kite, it might be worth giving this some attention before leaving the shop.
For the rest of this page, I just refer to 'the knot'.
This can also mean 'the ring' or 'the clip'. OK?
On our MBK kites, a
small length of line is attached to the rest of the bridle with the Prusik knot. Adjusting the towing point is as simple as sliding
the knot one way or the other, and then locking it. Using a fingernail helps, if the knot is
a bit tight to slide in the unlocked state.
Perhaps there's simply not enough wind for flying a kite. This is likely to be the case if you can't feel the kite pulling on the line. Just wait for better conditions, and go out when there's more wind! Alternatively, you could attempt to re-live your childhood and excitedly scamper across the field, towing the kite up as you go...
Perhaps you can feel
the kite pulling, and it moves left or right but just doesn't climb no
matter what you do. That is the symptom of a towing point set too far
back. Just shift it forward towards the nose of the kite a little, and
try again. Keep adjusting by a small amount until the kite willingly
climbs into the air. Learning how to fly a kite has a lot to do with
understanding this adjustment.
What if the kite takes off, but then just wants to loop around and dive into the ground?
Let's assume you're not trying to fly immediately downwind of your house or some other huge obstacle! Looping is usually caused by trying to fly when the wind is too strong for the kite. The first thing to try in windy weather is to shift the towing point forward a little. This reduces the pressure on the kite and might be enough to keep it in the air.
Be aware that shifting the knot way too far forward in almost any kind of wind will make the kite unstable! Lots of quick little loops and no satisfaction.
If you have shifted the knot several times without any success, it's time to add a tail. Or, if the kite already has a tail, add some more! Keep adding tail until the kite stays in the air, or you run out of tail material. If the kite is still misbehaving, pack up and wait for a less windy day!
However, if you are having some success at this point, you might even be able to shift the knot back a fraction. This will make the kite fly even higher.
one more comment here. If you made it yourself, but the kite just won't
fly straight despite perfect weather conditions, there is something
else wrong. Try this page to find the answers.
What if the kite takes off and climbs, but then doesn't get very high?
In this case it sounds like there is enough wind, but the towing point has been left too far forward. Perhaps the last time it flew, it was adjusted for very windy weather! No problem, just shift the knot back towards the tail a bit at a time until you are happy with how the kite is flying. Make small adjustments, or you could end up with the kite not flying at all!
shifting the knot doesn't help, then the wind is just not
strong enough to carry the kite to its maximum height. The tiny amount
of lift it is generating is equal to the weight of the flying line plus
the weight of the kite. It's a delicate tug-of-war between the kite and
the line. The weight of the line does add up, as you let more and more of it out.
Although this is something that you can't adjust in a hurry, it's worth noting in case you ever make a complete bridle from scratch. Either for a retail kite or for one of your own...
There is an ideal bridle length for any individual kite. That is, the distance from the sail to the tow point in flight.
If this distance is too short, flight can be less smooth, with the nose of the kite bobbing up and down in response to turbulence or changes in wind speed.
If this distance is too long, the kite will fly very smoothly, but will tend to gain and lose large amounts of height in response to wind speed variations. When the breeze drops, your kite will quickly start to tail-slide earthwards! Also, a kite on a long bridle will be a little harder to launch in light winds.
I find the happy medium for most of my kites is a length comparable to
the width of the kite, or a little more. Experiment until you find what
your own preference is. The original Dowel Sode had an overly long
bridle but it was kind of fun to fly it like that!
I hope these tips on how to adjust the tow point prove useful for you!
