A sport kite, also commonly
known as a stunt kite, is a kite that can be maneuvered in the air. A related kite
also controllable and used for recreation, but capable of generating a
significant amount of pull and used for providing movement is the Power kite
Developments in multi-line kites in recent
years has allowed forms of kite
flying to develop
into a sport.
Kitecompetitions have much in common with figure
skating, with competitors being judged on their performance incompulsory
figures as well as a
"ballet",
which involves artistic interpretation of music.
Performances are done as individuals, a pair of pilots, or as a team. Team
flying is typically the most spectacular, with up to eight pilots, their kites
flying within inches of each other and narrowly averting disaster, while
performing all manner of figures and formations in the air. Competitions are
held nationally and internationally under the auspices ofSport
Team and Competitive Kiting (STACK).
There is a bi-annual World
Championship which was
last held at Berck sur Mer, France in April 2014 and won for the third
consecutive time by British team 'The Scratch Bunnies'. They are the first ever
team to hold the title on three consecutive occasions.
In the United
States, the American Kitefliers Association (AKA)[1] is the umbrella organization for
sport kite contests. Competition winners from the various regions are invited
to the annual AKA convention for national championships.
In 1996 the
AKA, STACK, and All-Japanese Sport Kite Association (AJSKA) formed the
International Rule Book Committee (IRBC) to standardize rules and processes
.

Configuration
The most
common configuration for a sport kite is a roughly triangular "delta" shape, with two
lines for control. These kites are normally constructed from lightweightripstop
nylon or ripstop
polyester with spars
made from carbon fiber tubing. The flying lines are made from braidedultra-high-molecular-weight
polyethylene, which is light, does not stretch and stays slippery even
when wrapped many times.
To control
the kite, the pilot pulls on the right hand line to turn right, left line to
turn left, and so on. The pitch can sometimes be controlled by walking/running
forward or backwards, giving the lines different amounts of tension. Using a
combination of pulls and pushes (to give slack to the lines), complex tricks
and patterns can be flown. These range in difficulty from turns, loops and
landings, to maneuvers where the kite is flipped and turned end over end,
wrapping the lines or floating on its front or back. During diving maneuvers
sport kites may reach speeds of 60 mph, while in stall type maneuvers they
can remain nearly motionless. This type of stall allows for various other
acrobatic maneuvers to be performed.
Technology
Sport kites
can be designed to fly in a wide range of conditions. Most standard kites fly
best in winds from 3–9 miles per hour. High wind kites can be flown in very
strong winds of 30 mph or more. There are kites made from the lightest
materials that can be flown in the slightest breeze or even indoors. Novice or
first time fliers may have difficulty flying a dual line kite. For smooth and
consistent flying, a steady breeze is required, uninhibited by trees,
buildings, hills, or other tall objects which may block the wind.
A dual line
stunt kite can range from anywhere from $50 for a beginner kite, to over $300
for specialized competition kites made from high grade materials such ascarbon
fiber and Mylar.
Some high performance kites have optional tail weight attachments, which change
the flight characteristics of the kite, making some advanced maneuvers easier
or more dramatic.
Some pilots
also fly four-line (or "quad-line") kites, which are controlled with
a pair of handles, each with two lines attached to the top and bottom and
attached to the kite correspondingly. To control the kite, the pilot pulls on
the lower line to turn the kite in that direction. Skilled use of these handles
allows a quad-line kite to perform in ways that are difficult or impossible
with a dual-line kite. Unique quad line maneuvers include reverse flight, axis
spins, hovers, and side to side flight.
Other aspects
of sport kiting include power or traction kites, which can be used
to tow wheeled kite
buggies (kite
buggying) or surfboards (kite
surfing). Power kites vary in size from "trainers" which often
have dual lines and a small sail area, to large full size traction kites with
four lines, designed to pull people on kite
boards or vehicles.
Accessories
Many sport
kite pilots have a variety of line sets, in different lengths and strengths
(Measured in Lbs) to suit the wind conditions. Specialized kite bags are
designed to tote a collection of kites, along with line sets and repair
materials such astedlar tape (for fixing punctured sails) and
spare parts. Kite cases or bags also facilitate traveling with kites, some
designed to fit into the overhead
compartments on airplanes.
Other accessories include hand-held (digital) anemometers for accurate wind speed information
and LED lights that attach to the frame of
the kite to allow for night flying. Some manufacturers offer replacement spars
or spare components for their kites, for replacing damaged components after a
particularly unforgiving crash landing.
Types
There are
three main categories of sport kites:
Traditional
Sport Kites
Traditional
sport kites were most prevalent in the mid-90s and early 2000s. The kites were
built for precision, and were often fairly large and generated a decent amount
of pull. Such kites are considered "old school" today and they have
largely be replaced with more agile designs capable of pitch tricks.
Trick Kites
Trick kites
became popular after the early 2000s. The kites sacrificed some precision for
the ability to perform 3D acrobatic maneuvers. These kites have spawned a new
free-style type of flying where the flyer strings together tricks.
Quad-Line
Kites
Quad line
kites first hit the kiting scene in 1988 with the invention of the "Neos
Omega," later called the "Revolution 1." Quad line kites gained popularity
after sport kite team iQuad was formed in 2006. Revolution has dominated the
quad-line market, with only a few competing kites from manufacturers like Prism
and New Tech Kites. Quad line kites are noticeable by the way that they can
hover in space unlike any other sport kite. These kites can be extremely
precise.
