· Lead time for kites can be short (2 to 5 weeks), but it's often longer (6 to 12 weeks or more), depending on the number and sizes of kites already on order plus, a chaos factor. Since the situation can change over the course of a single day, lead time is well-nigh unpredictable.
· We make kites only after receipt of payment; not in response to telephone requests alone.
· LIMIT: Two kites per order.
· We do not do free repairs or supply free replacement parts, and we don't re-build kites made by other people even if it is claimed they were made by us—worn out, UV damaged, rotted, oxidized, shredded, severely stretched or otherwise mis-shapen kites cannot be repaired.

Please remember to supply a contact phone number for all deliveries outside the UK

Flying Line

Choose the right line for the the kite!

The line is an integral part of the kite+line system.

Line is chosen on the basis of both the size of the kite and the wind it flies in. You need light line for small kites and heavier line for big ones, and for any given size you need light line for light wind and heavy line for strong wind.

Rough guide to choosing flying line

For light wind, use a breaking strain (in pounds) of 2 to 3.5 times the square footage of the kite (rounded to the nearest square foot).

5 or 6 times the wing area is "normal," while for stronger winds use 8 times or more.


50-55lb for Little Bears & Whirlwinds in light winds
55-88lb for Clippers in light winds and Whirlwinds & Wildcards in light-to-medium winds
88-110lb for R7 & M7
110-125lb for Wildcards in breezier weather, and anything from
125-200lb (or more) for Troopers

At the Round Pond in Kensington Gardens most flyers used 80lb line regardless—just in case a kite got stuck in a tree, where lighter lines could break with the tugging. With 80lb line they'd more than likely get the kite back (though not necessarily undamaged).

Typical flying line: braided polyester. It has low stretch (less than 4%) which gives good responsiveness. It's reasonably priced, though price varies with quality. It's made for fishing and therefore readily available. Go for uncoated line, or a non-sticky coating. Waxed line can stick to itself on reels, requiring you to pull the line off by hand in light breezes.

The cheapest lines are twisted nylon and monofilament nylon. I still use some old twisted nylon on one reel. Although initially it's a little too stretchy, it's durable and really good for tying knots. Monofilament, also commonly used for angling, is relatively inexpensive, and because it's so smooth gives good flying angles. However tempting, it should be avoided for serious kite flying. While safe to use when brand new, it can part suddenly without warning after it's been used a few times. All it takes is one little innocuous kink to weaken it at a point, creating a stress concentration. You probably won't notice anything until it's too late.

Top of the food chain are the so-called "high tech" lines. These are aramid and coramid fiber lines with sensational strength for their thickness. They go by a variety of trade names. A line that looks like dental floss can have a breaking strain of nearly 200 pounds. Low weight and minimal drag mean high flights and stupendous flying angles, and with almost zero stretch kites flown on them are super-responsive. They do not come cheap, and there are a couple of other downsides to them in addition to cost.

One is that they can be downright dangerous, especially on big kites that pull hard. Think: cheese cutter. They have been known to cut the metal frame of a baby's pram. They've sliced through gloves, skin and tendons. And some can cut through themselves wherever there are knots, which is the reason for sleeving. My now fairly old 50lb Kevlar® line had to be sleeved, which put me off high tech lines for over a decade, but it has never failed. Now, there are "superbraids" with a hard coating applied to the outer fibers, meaning they no longer need sleeving at knots. (Sleeving kits are available from line suppliers for any line that needs it. Alternatively, one can make do with a darning needle or length of thin wire folded back on itself, and some braided nylon utility cord with the inner fibers pulled out.)

Superbraids can be surprisingly difficult to cut intentionally. Special tools are sold for the job, though one can manage without them. Field repairs could be tedious not only because of the difficult cutting and trimming, but also because the stickiness of the hard coating makes many normal knots awkward, if not almost impossible, to snug up neatly and properly. Still, many flyers feel the gain in performance is worth the effort. I have two reels loaded with these lines. In light winds they are astonishing, and in strong winds their minimal drag allows kites to climb to significantly steeper angles than they could with ordinary line. 1,000 feet of 80lb twisted nylon has about 4 square feet of surface area and significant weight. The equivalent superbraid is much thinner and lighter, and can seemingly double a kite's performance. For strong winds heavier lines with a higher breaking strain than necessary can be used for an extra margin of safety and still allow the extra flying angle.

An assortment of lines is essential for flying in a wide range of winds.

The force the wind exerts varies with the square of the wind speed. With light line you'll get the steepest flying angle and the best possible performance in light winds and thermals, while heavier lines give more steadiness and stability in breezier conditions.

For example, consider line 1/16th of an inch in diameter. 1,000 feet adds up to over 5 square feet of surface area, which equals a fair bit of drag in addition to its shear weight. Modern, super-thin, high-tech aramid or coramid line makes a very significant difference in light winds. The reverse is true for strong winds. Extra-heavy line helps to counter-balance the pull, and the line's inertia and drag help keep everything steady, leaving the kite more manageable.

So, having a selection of lines is most useful, but if you have only one reel, the trick is to have kites for different winds that all require the particular line you've got. In practice, especially if all one's kites are within a particular size range, 2 or 3 lines cover most situations.

Line care and attention

Kite lines can break suddenly and unexpectedly. Sometimes it can take no more than a quick jerk or tug from a thermal, or a burst of turbulence. Sometimes there's an almost invisible weak spot on the line, or some small cut or wear. The line may even be brand new. As the Scouts say, "Be prepared."

Watch when winding line onto reels - make sure it goes on evenly and flat; nurture the habit of winding with a side-to-side action so you don't have to watch it constantly. The objective is to avoid a buildup of coils of line at the reel sides, which can roll off under tension. The line can then pull underneath and get severely stuck in what we call a "bird's nest."

Through normal use, kite lines eventually develop weak spots. Always keep an eye on your flying line as it goes out or comes in. Be on the lookout for frayed spots, cuts, pronounced kinks, surface abrasion - any damage that could weaken the line. Cut these out then-and-there and use a Blood Knot (or Double Grinner) to join the line. A small, sharp pocket knife (or scissors) comes in handy in the field, as does a cheap lighter for melting the raw ends of knots after trimming - in a pinch it could all be done with just a lighter. Replace worn out line before it breaks!

The first 10 or 15 yards of line at the swivel end is most likely to show signs of wear, and can be chopped off periodically, re-tying the swivel; this job is best done at home.

Never leave discarded sections of old flying line in the field.

A word about knots

Bear in mind that line won't be stronger than the weakest links, so it pays to learn a few good knots. Fishermen have an arsenal of excellent knots; for the rest of us a good knot book is a useful reference. Try to find one that indicates the relative strengths of the knots, and look for knots between 90 or 95 and 100% efficiency. Many common knots actually weaken the line, reducing its strength by as much as 50% or more.

HARDWARE: click on links for details
Swivels / Snap Swivels / Link Swivels
Snap swivels consist of a snap and a swivel. Many (though not all) ready-made snap swivels are sold with breaking strains based on the stronger of those two parts, not the weakest - usually a bulky swivel on a weaker snap. Now, with cheap, poorly-made copies made from inferior metals flooding the tackle market, you don't get breaking strains at all. Therefore I began making up my own, all suitable for kite flying.
  • Using swivels significantly stronger than the line gives a long and reliable service life.
  • Big snap links are easier to handle than small ones.
  • Kite flying swivels have to endure prolonged periods of heavy tension. Test-rated components made to very high standards from high quality metals are both strong and reliable, while poorly-made, base-metal copies made with inadequate quality control cannot be given breaking strains and can fail at surprisingly low loads. (My friend had a materials lab tensile testing machine for a few years. Ever since I first used it I have sought only swivels from trustworthy name brands.)

    Why (most) experienced kite flyers use swivels
  • Swivels with snap links make changing kites or line in the field quick and easy.
  • The line end will not be weakened by the wear-and-tear of frequent tying and untying.
  • Winding in the last few hundred feet of line without a swivel can be hampered by a tangled build-up of twists, especially if winding in by hand without the aid of a deep-sky reel.

Deep Sky Reel from Into the Wind - No Longer Made

Deep Sky Reels

No longer being made:

Deep Sky Reel from Into the Wind
Into the Wind in Boulder, Colorado, USA, supplied these deep sky reels until their maker sadly was no longer able to build them.

For many years it was the only proper "deep sky" reel I knew of available anywhere. Had I ever needed a new reel, it would have been one of these.

Some Reel Tips

It's always best to make sure everything is snug before using a reel for the first time, and to take a tool or two along just in case something works loose in the field - even if it's brand new. The central nut on the main axle and its counterpart out of sight inside the hand plate are the most likely candidates, but the nuts securing the knobs can work loose on a new reel, too, as was the case here.

Things can work loose on new reels of this type; it's worth taking one partially apart when it's new and re-assembling it to make sure everything is nice and snug before loading it up and putting it to work for the first time.Round Pond June 1952

It's just the right size and capacity. It's smooth, well balanced, and doesn't wobble when it spins. It's almost an exact replica of the reels Gabriel at the Round Pond in London's Kensington Gardens made in the 1950s, '60s and '70s, if not before. I still use three of his originals.

Hoop SpoolHoop Spools
8in/20cm diameter x 1½in/4cm wide

These plastic kite spools are the next best thing to proper deep-sky reels (see below). They're light, easy to carry and inexpensive. They hold plenty of line, and wind in a lot per turn. Letting line out with drag is easy, and the grip is comfortable for any length of time.

"Yo-yo" Spools (if you can find them) are similar to Hoop Spools, but asymmetrical: one of the side flanges is slanted outward so the line can literally fly off if they're turned sideways or left lying on the ground. They're especially good for letting line out fast.

Wind meters and other weather instruments

Kaindl Windtronic 2
This is a favorite of mine - it suits my local swirly conditions by virtue of being omnidirectional - it's also very sensitive
the instruction sheet says it floats, so I presume that means it's rainproof, too
May take some shopping around to find
My Windtronic 2 was on sale, but the omnidirectional Skywatch Meteos and Atmos can be also be recommended (for the same reason, although I don't see a Beaufort scale on the Atmos). A couple of websites list the Meteos as discontinued; nevertheless, there are still over 2,000 pages of references to them on Google
Andrew Jones (aka "Wilf"), co-inventer of the Flexifoil, made his own pocketable, hand-held, omnidirectional anemometer some time before 1970. It had three folding, lightweight cups that generated a current through a small electric motor used as a generator, and had a hand-drawn scale that had been calibrated in the wind tunnel at Cambridge University. I thought it was ingenious. Incidentally, small directional wind meters use a spinning propeller whose revolutions are counted by a photoelectric cell, which is also interesting.
