One of the most popular sections of the GWTW Forum has long been the Swap Meet.  A great place to sell old, seldom flown kites or to get great deals on used (gently flown) kites.  Only registered users can see the Swap Meet section, let alone wheel and deal.  1000's (literally) of kites have changed hands thanks to the Swap Meet.
There are several more benefits to being a registered user, but you'll have to join our little community to find out all the "secrets".

Thanks, John, for posting.  I was wondering what would be new for 2016. 

I want one of those long skeleton kites with day of the dead faces from Premier . (Are those new kites?)

Nice one!

I added your picture to the Sixth Sense builds page

About the Sixth Sense UL: (and this is my personal opinion!)
After I flew the Sixth Sense STD Pro I liked it very much! I wanted the UL, so I build myself a nice matching UL Pro.
I did not like it at all...
It did not feel as the UL-version of the STD. It may be a nice UL, but just not the light version of the great STD.

It is very light. In the full 3PT-version it flies in the lightest breeze. It is very floaty.
Tricks are sloooow. For a Tazmachine you have to hit it quite exact. Falling in a backflip needs time. A Yoyo is only possible as Two-Pops (but very reliable).
Yeah, what ^he^ said.

The UL is very floaty and slow - it pitches well and so remains tricky - but not in a particularly fun way - at least not for me.

Perhaps it is just too light in full 3PT ? A slightly heavier framing mix might make it quick to trick and transition without impact its lower range too much ?

Back to the dualie project, I had plans printed this week at 4', 5', 6', 7', 8' (100%), 9',10', 11' scaling factors. The plans are aligned on the left wingtip. Am not sure which I will pursue first if at all. Each would be a unique effort as once you have a sail it takes time to find the right framing, bridle, standoff, and trim settings for a given kite.  The rules change as the size and scale change.

The little 4' micro is really cute and may just start with that. Could use a single 2pt LE and have a nice urban flyer for small spaces on short lines.  With a P2X frame it could be a high wind trickster. Maybe.

The 11' monster is the largest kite I could do with 44" tubes.

We'll see...





I look forward to the large ones!
I will probably be messaging you soon for a UL Enigma. Smiley

John,

Thank you for the complement.  My goal is to assist kite flyers in adjusting their glider kites to obtain the best performance.  Please don't be afraid to tinker.  As a recommendation, balance your Bird of Prey 48 upside down on your finger along the center spine, with the center spine parallel to the ground, and then measure this location from the nose of the sail (not the end cap).  This will give you a reference point to work from.  The balance point (Center of Gravity) that has worked for me and is indicate on the plans is 10 13/16 in. from the nose of the sail.  It would be my suggestion that you try some large vinyl end caps on the nose, cut to difference lengths, to fine tune the glide to your liking.  When you make a change to the nose weight, re-measure the balance point and write down its location, the associated nose weight that you used and your observations of the glide.  This information will assist you in dialing in the balance point that works the best for you.  Also, changing the weight of the flying line will change the glide and performance.  I prefer to fly my glider kites using Spectra line because itís lighter and has less drag than Dacron.  As your glider kite takes more line, this weight and drag of the line acts like additional nose weight.  Since the Bird of Prey glider kites have less pull on the flying line, as compared to a conventional shaped kite, you can use a lighter flying line.  You just need to be careful if you are flying around others that are using Dacron line.

Please note the Bird of Prey 48 made from PC-31 has about twice the sail loading of a Bird of Prey or Hawk made from 0.34 Cuben Fabric.  As the result of this additional sail loading, the stall speed and glide speed will be about twice as much.  The advantage of a high sail loading is that you can be more aggressive with this glider kite, because the weight will carry the glider kite through your maneuvers due to inertia.  I have a blast flying my Bird of Prey 48 is light winds, where I can use the wind and sail loading to my advantage and do climbing snap spins down the field.  For indoors, my go to glider kite is the Bird of Prey 36 made from Cuben Fabric.  I will be using the multi-panel/color version made from Cuben Fabric for this season because the slightly higher sail loading allows me to be a little more aggressive with my indoor routines.  Also the multi-panel/colors are easier to see for the audience and judges.

I am not sure where you are located, but for your information I have been requested by Archie Stewart and Steve Santos to present a clinic on trimming glider kites at the Kite Mania North 2016, which will be held in Dedham, MA on April 16 and 17, 2016.  The details of the event are in process, but my presentation will include an overview of aerodynamics as they apply to glider kites, then a hands-on session to allow kite fliers to see and feel how different configurations and trim settings change the performance of a glider kite.  I also will be available to help kite flyers perform trim adjustments on their glider kites.

Yours in kiting,

Doug

Nice work Brian  Cool  The attention to details makes all the difference.

I agree with the leech line also. Tight or loose, all kites should have them to control the TE and hold shape.

Yes more should post their build efforts.  Much to learn and share.  Thanks for posting.

I think you've build a very nice Sixth Sense Pro, not a nonstandard.
I never built a Sixth Sense without a leechline Smiley

The 5 grams you are missing in the Lower Leading Edges can be missed in some flatspins, or maybe the Yoyo. But I agree it won't make a big difference.

Sewing looks very nice!

Two things: the trailing edge needs some protection. It will wear through the spinnaker after enough flighthours. I always use an extra 2.5cm strip with a length of 30cm from the outer standoff to the tail. Yours will wear next to the inner-standoff after lots of Lazies, Multilazies and Yoyo-related tricks.
Do not fix it right now, it can life long enough. Just remember this for your next build.
I also don't like this: (green circles)

It is a perfect linecatcher like this! I also did it this way a few kites ago.  Cheesy Make it just point the other way, or rectangular (I do this).

Again: nice first build!
