Thanks!  I've used Seattle fabrics for some nylons, webbing and velcro.  They don't have cuben ...

ZPacks also carries the very light Cuben in orange, as indicated in the following link.  I prefer the light grey from questoutfitters.

Back to my other kite construction projects, while we wait for a snowstorm in the northeast.

Have a happy and safe New Year’s evening.

The following drawing is the color layout for a 48 in. and 62 in. wing span version of my Bird of Prey swept forward wing single line glider kite.  Just couldn't resist making it look like a stealth fighter with USA colors.  The sail material will be PC31 and the frames will be small diameter hollow carbon tubes, which diameters will be selected during construction.  I have 0.08, 0.098 and 0.125 in. diameter carbon tubes to try out.  The plans are done for the 48 in. version.  I will finish the plans for the 62 in. version by the weekend.

This weekend I will start these two glider kites, along with my X-29 canard glider kite.  While waiting for the materials, I will sew together the stunt kite version of my Rapere.

Didn't get much kite building completed over the holiday break, because of enjoyable hours with my family.  My 23 year old son was home from LA for two weeks, where he is a musician (lead guitarist and backup singer) with the band Blondfire.  He also does session work for others in the LA area.  Also, we just held the Boy Scout Eagle Ceremony for my 18 year old son, who will be off to college this fall.  Great times in the Stout house hold.

Later,

Doug

The following provides a picture of the Bird of Prey with a 48 inch wing span.  Up is the direction of flight.  The kite weighs 32.5 grams and is framed with 0.08 inch carbon tubes for the wing spars and center spine, with 0.03 carbon rods for the tip battens.  The sail material is PC31.  I went with the color charcoal for the simulated canopy, which has outlined in white pin stripes.  Could make it a bit lighter if I used fewer colors, but it looks so cool in the air.  Still very light for it size, for a great outdoor zero/light wind glider.

The following provides an angled view of the Bird of Prey 48.  Waiting for the snow to stop up here in the northeast to take pictures while in flight.  In this picture, you can see the outline of the simulated canopy with white pin stripes.

Due to our lovely winter weather, I am almost done sewing the sail for the 62 inch wing span version.  Just need to finish sewing the balance of the reinforcements.  Should have it completed this week.

I flew the 48 inch version outside on Friday in the snow.  It looks really cool in the air.  Will try to take some in flight pictures when there is a fresh layer of snow covering all of the ice.

Later,

Doug

... and then there were three...

The attached picture shows the three sizes of my Bird of Prey.  Just finished the 62 inch wing span version, which is on the left.  The 24 inch wing span version is in the middle, while the 48 inch wing span version is on the right.  I hope to get the 62 in the air when the snow stops.  The 24 inch made from Cuben is still my favorite for ultra-light flying.  Thinking of building an ultra-light version of the 48 using Cuben.  They are very efficient gliders.

The attached picture is the larger Bird of Prey backlit with natural lighting.  It has a 62 inch wing span, 35 inches in length, with a project sail area of 867 square inches.  It weighs 57.9 grams balanced at my center of gravity starting point, which is on the mark with a sail loading of 0.339 grams/square inch of projected sail area.  Time to get this Bird some air time!
