Title: Indoor Zen Glider Flight
Post by: GEB on September 22, 2009, 03:15 PM
At WSIKF this year Jim Cosca flew a small glider during indoor demonstrations that was built by Daryl Yeh. Does anyone have more information on this kite. YouTube has the video under "Indoor Zen Glider Flight". It was a great demonstration.

that kite appeared in online pix and videos last year....litsong has spoken to Daryl and he is reluctant to part with them very often......

that video does show the effect using a control rod can provide while flying a kite indoors!!!!!!!!!

Jim flew that thing at one of our recent indoor fun flies...and it is, to use the vernacular, "sick"!! Everbody went bonkers for that kite. It's truly awesome. We couldn't believe how well balanced and tuned it is.

Balanced and tuned it is. It looks faster in the video than it did in person. By comparison it made the Skate, which is a great slow gliding kite, look really fast. I want one !!!

Thanks for posting the video. The lighting in the gym makes the kite a little hard to see at times, but the end of the video shows the speed and balance clearly. Jim did an excellent job of flying it and picking just the right music for the kite. Very mellow, very Zen like.

So did any of you see it up close? Is it built like a fighter kite, or what? I've already tried my hand at building two imitations, but I'm not close to that amazingly slow flat glide. . .

BTW, John Baressi has posted a video of him flying a similarly capable glider-kite in early 2007. It's the second half of this YouTube video, starting around 5 minutes in (the first part is an indoor Rev): Adios Nonino (indoor kite flying) (http://www.youtube.com/watch?v=tjrwsKVkEls#normal) .

John's style is definitely NOT flying while sitting in a chair, but it looks to me as if the kite might do it.

I posted there asking John to share some general (or even specific! ;)) info about the kite. I might as well ask here, too -- tell us all about the glider-kite if you're willing, JB!!

i am going to guess that John is flying a Nelson Borelli fighter kite....
not available to purchase but as i understand it he does offer them as a workshop kite....

Correct on it being Borelli's kite... A "fighter floater", if you will.

VERY light (light trash bag material), it is truly a workshop kite, but flies so easily... You can pull it up overhead, let go on the line, and watch it lazily circle overhead as it very slowly comes down.

Anyone can fly one of these, it's not a finicky (for input) as a typical fighter. ;)

I made myself a Borelli Glider out of icarex some time back. Didn't thrill me indoors (probably due to my poor construction on my first attempt), but it's been a champ outdoors as a light wind kite. Here's a link to the plan. This is the only place I've ever been able to find it.

refer to following web
 
http://www.batoco.org/planos/2008/04/planobarriletegliderborreli.html (http://www.batoco.org/planos/2008/04/planobarriletegliderborreli.html)

Let Try for OD 0.5 ~ 0.8mm spar, 1.5mm is too heavey, The spars can get it from RC Aeroplane frame material, With 1.5mm spar the wing span need to be Larger or bigger, For 0.8mm spar with orcon sheet 0.5 Oz the wing span may need up to 54" or above then it will find the effect. The kite try it to be bridless and tie a swivel and Swivel weight can perform the balance of the kites.

The above is a zen indoor kite fly.

There's a PDF version of the plans and commentary, too, including full-size plans and templates. The page says it's "727 Mb", but it's only 727 KB.

There are also 3 videos on the site. In at least one of them, it's clear that the video-kite is not balanced to glide un-tended -- it stalls and dives a few times.

And in a bunch of the video the main attraction is the flier whipping the kite around and around on about 3' of line at high speed, to music.

I guess it's a personal taste thing, but that doesn't do anything for me, since I could do that with a lead weight at the end of a 3' line. . .

By my math, 0.5mm is around 0.02", which is very thin Carbon Fibre. I've been playing with 0.03" -- though it doesn't seem to flex enough for a ~24"W glider-kite. I "hinged" my current version by cracking the bow at the spine. Then I made a little dihedral by hot-bending a short piece of CF, and I taped it on top of the middle of the bow. So the kite never goes totally flat, and it is still semi-hinged at the spine -- i.e., it flexes more at the spine than along the 0.03" cross-bow. (I posted a few more details on Bruce Lambert's http://fighterkitecentral.com (http://fighterkitecentral.com) site.)

Mind you, 0.03" is still pretty flexy micro-carbon, but these super-slow glider-kites are obviously VERY flexible.

As siajauren indicates, there's a clear relationship between spar-flex and kite size.

I'm fascinated by the idea of using a swivel instead of a bridle. Mine has a simple 2-point bridle, like an Indian Fighter kite.

Hey Siajuaren:
how fast are you able to reel in and let out the line?
I have found that using any sort of spool does not work for me since it is not fast enough to my liking....

Zen fly is your emotional control fly, This fly is to train the kiters mentalities, otherwise the kite will damage cause by strong pull. The spar for this kites is 0.5 ~0.7mm.
Please be careful when fly this kite.
 
I just get this kite and started to learn flying it since last week, But fly it in my dining room in night time before sleep  :P

Does Daryl Yeh still sell the Zen Gliders?


Title: Re: Indoor Zen Glider Flight
Post by: thief on July 17, 2013, 06:32 AM
i would imagine that he does....he also makes and sells his "dream Bird".....his kites are NOT cheap at all......
There are some great xUL gliding kites out there for the grabbing.....
