modern power kites have become safer and

more versatile largely due to D power

systems this tutorial explains all of

the D power systems on a modern power

kite the ability to power or D power

your kite while flying it is actually

its ability to change angle compared to

the airflow known as angle of attack if

your kite lines up with the airflow it

will barely deflect it and won't pull

you as much if the kite has a larger

angle of attack then the wind is

deflected and the kite pulls harder it

is important to note however that if the

angle of attack is too great you start

to lose power too much angle of attack

makes the kite fly sluggishly around the

wind window and can even cause the kite

to fly backwards known as back stalling

the largest and quickest control over

your kites angle comes from the bar when

the bar is pulled in the steering lines

tents increasing the kites angle of

attack when the bars out the steering

lines loosen reducing the kites angle

and power

this is why students are trained to push

the bar away when confused or out of


many students unfortunately begin with

the opposite instinct

since panic makes you want to grip on

the bar as well as the bar you can

adjust the kites angle using the D power

strap basically this system works by

adjusting the length of the center lines


when you shorten the center lines the

steering lines loosen giving less power

when you extend the center lines the

steering lines tense which can increase

the power you feel from the kite the D

power strap isn't designed to give

on-the-go adjustments like the bar but

it is helpful for trimming your setup

for example here the kite er is leaning

forward to reach the bar this is

spoiling their upwind stance shortening

the D power rope means the bar can sit

closer as you ride on some designs you

may find your D power strap below the

bar or you may even have two separate

taps but this still works on the same

principle the power tap will extend the

centre lines the D power tab will

shorten the centre lines the final way

to alter the angle of the kite is by

using the different connection points

that join your lines to the kite

typically you will find three knots to

choose from when connecting your

steering lines to the kite attaching to

the first not slightly extends the

steering lines for less power

attaching to the third knot or last not

slightly shortens the steering lines for

more power


there could also be multiple connection

points to choose from on the

centerline's in this case the first knot

extends the center lines for more power

the last knot shortens the center lines

but less power

most kites are designed to work well on

the middle settings although it can be

hard for beginners to notice if their

setup and rigging are optimal generally

speaking when the bar is pulled in

straight the steering line should become

tense but the kite shouldn't stall or

steer when the bar is pushed out the

steering line should become slack it is

common for people to make rigging

mistakes in light wind because the wind

is light they decide to set up the kite

for the most power these settings give

the most angle of attack possible

however too much angle-of-attack slows

the kite as you try to maneuver it and

in light wind make the kite liable to

back stall using some D power however

helps the leading-edge fly forward

quickly the clack can then be steered

deeper into the wind window to build

power in strong wind it may help a

little to rig for less power

before you launch but bear in mind this

doesn't make a huge difference in strong

wind full D power will not allow you to

use a kite that is too big for the wind



I hope this tutorial helps you
