Pacific Kites Express



Appearing for the first time at the Coupe du Mont Faucon 1984 were the first models of Express.
Since the Coupe du Mont Faucon where the Express appeared much faster than its competitors, André Chairou has "civilized" his prototype. The profile in the central part was thickened to improve the characteristics at low speed. The trailing edge of the extrados like that of the intrados were no longer scalloped but rectilinear and reinforced by a strip. To increase the roll rate, the surface of the marginal edges had been decreased.
The 28 pounds of the Express was further diminished by the use of a transversal in 62 * 0.9 which no longer required sleeve. When lifting the unit the core lugs will easily skew and bend the cables. 8 slats on the extrados, 5 in the intrados. The fiberglass sticks which form the marginal edges are very easy to assemble. The leading edge is not mylarized. The sail is bathbridge 4.2.
For reasons of stability, the intrados is connected to the extrados by a system of adjustable velcros. On the Express, by inflating the extrados to 80% moves the center of thrust towards the rear. This reduces the recall to neutral. The binding extrados intrados fights against this effect. Care must therefore be taken to ensure that the connecting hooks are always secured and their length is symmetrical for each wing. Those relieving the last lath of intrados to the extrados have an influence on the stability spiral. Too tense, they diminish it, too much, they increase it.
The stall is rarely symmetrical and is often followed by a quarter turn during recovery. This characteristic is found at landing. If the rounding is negotiated at the right time, no problem but if it is made too high, one wing or the other will collapse first. These characteristics almost disappear with a "soft" setting.
The Express "Dacron" was made in France by Pacific Wings.
