Welcome to the GWTW Forum.
Guests (non-registered users) can view the forum but are unable to post.  If you don't have anything to say then why would you bother to register?
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".

There are actually 6 blue positions shown.
1 for the humerus
2 for the radius/ulna
1 for metacarpal 4
2 for the wing finger (one is fully folded in hyperextension and points back toward the shoulder)

The blue positions just illustrate range of motion of the articulations (some are terrestrial and have nothing to do with flight).

You can raise the head level if you use the swan-like neck positioning (which I would)

The animals landed in a near vertical position, took a couple of stutter steps with their hind limbs as they were folding their wings into terrestrial position, then dropped their front legs on the ground and walked away quadrupedally.

Thanks Bill  Smiley  Need to let the new kite smell wear off for the testers then see what they really think about the kite.  That feedback will help determine next steps.

Are the Carolinas ready for this?  Should I spare them the weather trauma and just keep it?

JimC,

Have the top and side outline of the Qsp drafted in AutoCad for an 8 foot and 4 foot version.  Time to figure out the framing, then refine the plans to make templates.  Will build the 4 foot version first as my construction and flight test bed.  Need to load the top view silhouette into my program to find the neutral point.  Regarding the legs, what angle should they be with respect to the center line of the neck/body?  This was not illustrated in the side view.

I have a question on the drawing you suggested to use.  Why does the right wing tip have two positions, with the blue one more forward?  Also with the nose (head) at a slight downward angle, ground landings will be interesting, so this glider kite version of the Qsp will be a fly and catch.

Later,

Doug

Sitting on the beach in the van tonight I have the following friends with me.  All old school except Lam's.

Elixir
Bad Boy SUL
Tekken mid vent
Peter Powell three stack
Alien
Rev 1.5 B std & mid

Flew the B std over a palm tree & crashed on the other side with the 65' lines draped across the top.  Got lucky & recovered them.  Walking around flying in the dark has it's hazards.  Next I flew the yellow Tekken for about an hour in the dark, great fun for a SHBKF.

Ara said it best! "Wow really nice kite and nice flying and nice video!"

So ...what is the deal with the Enigma? Is it going to be available for sale? Open source builder's plans? ...or what?   Tongue

Hi Tom,
1)  For the fun of it
2)  I have access to the original fossils and also keep casts of some of those fossils at home
3)  I have already built a 3-D articulated, photorealistic flying model.  That model even had 'fur' on the torso and 'mucus' draining from the corner of the eyes and nose.  Looked real till you touched it and noticed the skin was cold.

JimC,
 I have been following this thread as I am sure a lot of people are. I was wondering did you want to build a kite that is for lack of better description 2D? or are you looking to build one that is 3D? If you were thinking of going 3D have you thought about building the skeleton using 3D printing? There are several processes you could use.
There is SLS which uses powdered Nylon as the material. FDM uses several materials ABS, Polycarb. and Ultem.
You could also go with SLA which uses many different resins.

 What you would need though is a 3D rendering of all of the bones in SLA. file format. You could then scale that to any size you like to produce your model. From there you could skin the model in something that would simulate the skin. By picking the appropriate material to try and get as close to the weight of the Pterosaurs.

 Tihis is just my 2 cents worth. I find this subject very stimulating. Please keep us all posted.

Tom

JimC,

Surprised by your viewpoint.  From what can be made public, it's my opinion that NASA and DARPA are on the forefront of interesting developments, which results in advancements in materials and technologies that we can use to advance our respective fields of fly surrogates.  Since I canít tie my flying line to a living Raptor and encourage it to do what I would like in the air, I guess I will just have to use what mankind can provide as materials, as a surrogate for the living creature.  Works just fine for me.  Grin

As stated in the past, best of luck with your endeavors,

Doug
