Good morning, following with the help of friend Randy, I decided to bet on the construction of this 7m NPW 21. I am not a professional seamstress and
I get a lot of broken lines and bad seams, but I can solve the problems. My space is not professional and everything is done in improvisation. I am
using a 70g resin umbrella nylon, I have already used it on a 3.9m NPW5 and I have been very successful in the construction. I hope this one also has
the same or better performance than the previous one.

Looking good so far... Randy - 2-11-2020 at 05:33 PM
Looks very promising. Very clever to use the umbrella resin.
In my experience the NPW-21 design doesn't usually need much bridle adjustment. Getting the the trailing edge tension lines correct is import to stop
the wing flutter. Instead of a tension line I have put darts in some of my kites. Please keep us posted.

Good Morning. I'm leaving the issue of the trailing edge lines to the end, I'm still thinking about how I'm going to do something that I can regulate,
but I don't know if I'll be able to do it. Regarding the brake adjustments, I really like to use the kitesurf bar, so I know that the stop lines need
a little more length to be able to stay connected together with the other halters, at least that happened with my NPW5, but it's a detail very simple
to solve. I intend to do the first test next Saturday.borokite - 6-11-2020 at 05:22 AM
Good Morning.
Yesterday was the day to finish the lines, now just finish the terminals and put them on the air. This one I want to use the brakes to give me more
security and I want to use the Z terminal system on the brakes. Would anyone have any other depower system with good security to refer me? I still
miss having the kiteboard kite system installed at NASA, where I push the bar to lose strength and pull the bar to gain pressure. In the Nasa kites
because the main lines are connected at the tip of the bar and the lines of the flange edge in the center, I lose that possibility. I don't know if I
managed to be clear

Wow! Nice work. My bridle bar is just a board with a tape measure and nail in it. As far as depower, no one has been able to come up with anything
as effective as a kitersurfing depower for NPW's. There are a few systems like the Born method, the crunch the nose. You already seem to know about
that.
I tried the method you put in the picture above. You get very little depower range (it is more like being on and off). The kite turns very quickly,
sometimes flutters in turns. It does make it possible to prevent backstalls by pulling on the center line (or pushing the bar). If you pull too
much the nose collapses.

Regarding the NASA Star depower, I already made a 3-point connection on the bar on my 3.9 kite and I really lost a lot of energy from the kite, but
the problem was that the central line ends up with a very big curvature and weighing on the Kite. Watching some videos, I noticed in some stars a
depower system connected in 3 points, but the line goes to a system that is next to the main lines, it seems that the central line continues with
pressure, ideal for the bar to be able to slide up and down firmly as in traditional kites. Would anyone know how to give me more details on how to do
this procedure correctly?

Really, traditional control seems to have a lot more pressure and kite control, these quick turns without pressure and these sudden falls in reverse
completely take the pressure off the lines.Randy - 6-11-2020 at 08:20 AM
I agree. I don't use it any more. borokite - 9-11-2020 at 05:06 AM
This weekend was the test of my NPW21, after several line adjustments I managed to put it on the air.
My observations about the kite were:
Lots of tractive force.
Wider flight window.
Low speed.
Lots of vibration at the tips.
The kite is much wider compared to the NPW5, which makes it have a lower AR.
I still need to make more precise adjustments, reduce the tension lines, maybe create some darts, but taking into account the bad wind quality with
variation and gusts coming from L and NE direction, I really liked the result. Soon new videos. I will be honest in saying that I was a little scared
by the pressure of the kite on the bar, thinking that there might be some problem with the bar breaking.
