Don't scoff, it' true! A hang glider meet in Kansas! Yessir, and a lot of fun it was, too. OK, so we don't have the high hills that al 1 you birdmen have over most of the country; but, believe me, that doesn't mean that you can't hold a successful meet. You can, when organized by some enthusiastic people, incorporate some variety into have roast fire, lot' of (not , course) and have the support great bunch of local and not-so-local fliers.

No. The cable used most kite manufacturers meets specifications . It is not a true stainless a corrosion resistant steel. If a cable is go·· let go it will give a warning sign such as a heavily spot, or, most a strand.

Why do some manufacturers use one Nico sleeve, others two? Which is stronger?

A single Nico sleeve is 100% as strong as the cable when properly If on too loose, it could If on too , it pinch the cable a.nd cause to break inside the Nico. A swaging tool that has been "miked" will make a I have worked with three manufacturers, and reasons. two Nico sleeves gave the "We sell kits. A homebuilder not swage a Nico sleeve enough so we two Ni cos. We want our shop to set an for the homebuilders, so we two Nico's on all our kites After the Nico correctly, there a loose end might catch their sail, clothing, or flesh on. of an inch between the two Nicos, we put on a second one to cover up the loose ends. Two Ni cos also ease people's fears about the kite falling apart on them. A custome:t' might buy a kite from us because he thinks that two Ni cos a:t'e stronger. Two N:icos might give a flier confidence in his kite."

The manufacturer with one Nico gave the following reasons: "One Nico is 100% as strong as the wire. We manufacture as safe and strong a kite as possible keeping it light and clean for quick handling in the and easy as·· sembly on the ground and yet as durable as possible to our customeTs' investment protected with a re·· value.

"We have run tests on Nicos and have found that most of the tension is taken out of the wire in the friction of the cable going around the thimble and the Nico is really just there to hold the cable around the thimble. We have only half the Nico, and we have swaged the Nico half as as the tool stops, and the cable still before Nico can be made to slip."

Customers have then asked why do all sailboats use double Nicos·t I am not sure all sailboats use double Nicos. around I got two different answers 1. To sail from .loose cable ends.

That saine the cable inside the Nico will rot from the (but they could not tell me how two Nicos to stop this phenomenon) . Every have personally had just one Nico on the control cables.

3. Whichis aircraft or marine stainless steel cable? Somebody aircraft is much tougher.

If the mil number is the same, the cable will be the same The only difference between aircraft and marine steel cable ML-C-S424 is that the aircraft cable is impregnated with grease so the individual strands will not wear out rubbing against each other around while the marine is clean cable for use tension.
