As a result of a lot of trail and error I can ( proudly  Wink ) announce the new B'zar 2011. Key word for this model is broadseaming. By adding a little sailcloth to the theoretical seam you become a sail with an internal camber. In order to spread this camber in a logical way into the sail I had to rework the panel-layout.

The idea is to add some volume in the section right under the leading edge from nose to lower apa connector. This volume is locked into the seam and can not be reduced by to much tension at the wingtip for example.

There is also a curved seam in the middle of the sail at the spine. Not only from center T to the tail, that is generally known in most of the available plans but also from center T to the nose. This seam follows a natural swanneck(?)shape a spine tends to take if a kite is set up. This avoids that volumes determined by the broadseaming would be influenced by the deformation of the spine.

At last, I added some volume in a seam going from the inner standoff to the center T. Normally the sail is always very tight in this section, you usually see a wrinkle there. By adding some cloth in the seam you keep a curved shape of the sail in stead of a flat one.

I will come with some foto's soon.

This is what i've been waiting for. I've hold my urge to build the 2010 version and wait for the 2011 version after i've heard that you are working on it. Can't wait for the pictures and maybe a video of it. With all the add ons, the wingspan of the kite is still the same or roughly gonna be alittle wider??

Incorporating a couple of the idea's I've had rolling around in my head, I'll be anxious to see how you've done it since I haven't figured out or prototyped any of them yet.

Please pass on your thoughts of the benifits of these modifications, do you think they widened the wind range? Helped or worsed edge handling, precision, any of the tricks etc? Really looking forward to your flight opinions.

The first picture gives an idea about the panel lay-out, the seam starting at the nose has the extra cloth, and the seam starting above the center T going to the inner standoff also.
The second and third picture illustrate the curve of the spine wich is integrated in the central seam.

Before releasing a plan I just have to do some minor corrections coming out of the last tests. I think I will manage this in the days to come. The final version can be found soon on "tweelijners.be"

Some info about frame:
LE: P200 upper and lower
US: 6 mm pultruded
LS: Black Diamond Nitro Strong
Spine: P2X

Weight: 25 grams in tail

Bridle: Tri-axis turbobridle

About the flying: I hope a video will be available soon. Maybe this sunday or next week.
I find it difficult to discribe the flying but all I can say is that it tracks very well it can fly very sharp corners it flies in no less than 5 km / u, up to 20 km / u
Trick rating:
rotational moves, 540's axel etc: +++
lazy suzans: single or multi: ++++
Tazz machines: ++++
Backspin: also cascades: +++
Comete: ++ goes in a turtle while cometing if not good executed
Yoyo: +++
Slide and stall: ++++
JL: +++


In my opinion it is the most trickable precisionkite I know

wingspan is 2.35 m almost the same as the 2010 model. The extra sailcloth adds volume to the kite between fixed points so it doesn't effect the overall size

Sweet! Do you have those pictures uploaded to any other site where we could see a larger size so we could zoom in on some details? The GWTW pic post feature is great to have but the size limit doesn't allow much detail. Interested in the nose area, construction and the results of that added fabric. If I ever get a chance to build something soon this is moving to the top of the list right after a glider type SLK.

I am excited for this new bzar. I am pleased with the look of the new sail layout, and I fully intend on making this kite as soon as your plan is available. (was actually going to start another 2010 version build, but like the new layout so much that I'm going to wait for the new plans.). Thanks Werner for posting your plans for the public.  I love that I can build these exceptional kites for myself. It's so satisfying to fly something made by my own hand that out performs many of my purchased kites.
