     Please take a minute and read these instructions for:
             The NPW9b Buzzard Vnose 2003-10-22

* Please note that while the default 'Buzzard One' profile
uses the standard NPW9b building and bridling method (as
described at Jean-Pierres site http://freedom2000.free.fr), the
Buzzard Vnose has a different bridling at the nose. This
results in less distorsion of the sail, especially when going
fast against the wind, and permits the use of a more wing-like
profile. The result is a kite with higher performance.
The Buzzard Vnose profile has:
- more controllable pull, mainly due to a very high top speed
- a larger flying window
- a more agressive flying style with better acceleration

* The Vnose modification (which in summary consist of
shortening A1 by T*1.5 and replacing two T-lines with Extra
lines in the length of T*3.3) that is described below is necessary
for all 'Vnose' profiles to fly, but it does not necessarily enhance
all NPW9b profiles.

* It is not necessary to cut and sew the nose part of the A
(centre) panel. There is very little stress on the T lines,
especially so with the Extra line bridling. Sew only the B and C
wing panels to the full length (including nose) A panel
including a reinforcement cord in all 4 seams and at the
perimeter, as described by J-P. Then sew a reinforcement cord
across the underside of the A panel, at the nose borderline
where the T's will be attached.

* Please make sure you are using version 2.1.2 or higher of
J-P's NPW calculator - then all measurements will be correctly
displayed. When sewing the 5 darts on the nose, be very careful
to keep the width at the specified K value. To keep the sum of
these 5 K's exactly right (this is important for the final
shape of the nose), my suggestion is to make preliminary darts,
then measure the "top" of the nose (which should be equal to
the width B of the centre panel) and the "bottom" of the nose
carefully to see which total K value (the amount of shortening)
that the 5 darts have made _before_ sewing them permanently.

* Finish the sail as described by J-P, cut and tie all bridles
to the sail except A1. Attach only the five middle T lines, do
_not_ use the first and last T lines that attach to the corners
of the nose! These are replaced by the Extra line described
below.

* Fit the Extra bridle line between the corner of the nose and
where the side dart is folded (in other words: from where
bridle A1 normally is attached to a point M-N/2 along the
leading edge towards point B1). This line should have the
length T*3.3.

* Tie bridle A1 around this Extra line with a bridle knot.
This knot should be able to slide on the Extra line so that A1
can find its optimal position by itself. Do not worry if the
knot later becomes very tight - the sliding is only needed for
the first flight.

* In order to compensate for the length of the Extra line, bridle
A1 has been shortened by T*1.5 in the profile. To see the actual
profile of the Buzzard Vnose in the JPG NPW calculator, add
T*1.5 to A1 by typing in value 162.50 at box A1 with A=138
cm. To correctly scale the size of the kite, keep the correct A1
value of 153.50 for A=138 cm, change the A (height) value to
the size you want and then manually calculate the Extra line as
T*3.3.

* The only bridle that in my experience may need some
fine-tuning is A1. Making it slightly longer makes the nose
more stable while making it shorter increases the powerful
wing-properties of the kite. Too short A1 makes the nose prone
to collapsing - make small adjustments (no more than 0.5 cm at
a time) until the nose is in balance. The older tuning tips
for the 'Buzzard One' does NOT work on the Buzzard Vnose.

* If using the cascade type of bridling, please note that the
default secondary bridles B5 and B6 are quite short compared
to the primaries. This can be seen in the air as a slight
compression of the distance B5-B6 and also B3-B4. Therefore,
try to round the primary lengths _down_ after scaling the kite,
by changing the values in the primary boxes to a nice and
even number.

* If you are the fast-building type, anxious to get in the air
as soon as possible, please note that certain details are more
important than others to get exactly right. These are: The 5
nose darts and T-lines, bridles A1, B1-B6, brakes and the
Extra line at the nose.

* All bridle lengths have been carefully tuned on kites made
of low stretch rip-stop fabrics (such as Chikara, Shikarex,
Icarex) and bridle lines of spectra (primaries) and dacron
(secondaries). Any combination of these or similar materials
should therefore result in a high performing kite.
If you are using more stretchy fabrics or lines, various
bridle lengths might need tuning for optimum performance.
