Not quite--further postings in that thread (including a copied e-mail message from Dr. Z himself) indicate that he is in the process of re-negotiating a contract with the ammunition factory where he makes the Rapier motors. Also, the European Union has apparently classified Rapier motors as fireworks, which complicates the process of shipping them. Since they aren't explosive and are rather feeble as rockets go (they're like weakly self-propelled white-smoke flares), it should be possible to work out new shipping arrangements for them.

The glider in question is the NDC "Super Glider" . . . I had a couple of them and converted them to B/G's in the mid-1970's . . . Lost them to thermals.

Ah--thank you for posting this! (If the NDC Super Glider is no longer in production--although it's possible that some other company got the molds and is producing it under another name--3D printing would enable duplicate molds to be made; expanding foam would fill them, with small holes "venting" excess foam.) Also:

When we lived in the Blue Ridge Mountains of northern Georgia, a neighbor kid had one of those gliders. Its calm-air performance--we glided it downhill several hundred yards, through the "thinned" trees on our mountain, where a trail was located--was outstanding! I'm not surprised that you lost your boost-glider-converted ones to thermals.

Heartily agreed! I was thinking--if anyone here on YORF has an intact NDC Super Glider glider (or even a somewhat "nicked" one; with computers, "mirror images" of the "nicked" spots could be generated [using the 'un-nicked' opposite sides--or interpolation could be used if both spots were nicked], for 3D printing the molds), it should be possible to scan it with an optical contourometer, to generate high-fidelity 3D printed molds for them. (The optical contourometer is a pretty old device; even back in the 1950s, military jet pilots' helmets were custom-made to fit by scanning their heads with them [you can see this in the second and third images in the second row, *here*: https://www.google.com/search?sourc...0&bih=789&dpr=1 ], and modern, PC-compatible ones are now available, see: https://www.ebay.com/sch/i.html?_fr...w=contour+meter [I searched Ebay under the term, "object scanning contourometer"].)

I just found airfoil data . . .

Wow, this is my "thread that would not die" (neither shall I, once I have that single horn). Thank you for posting the NDC Super Glider photographs and wing airfoil section! (It is similar to what my father patiently sanded into his Estes Astron Falcon boost-glider's wings--just that slight "touch" of undercamber, which made a big difference; it would descend in 1/8th-mile circles, taking minutes to reach the ground!) Also:

The NDC Super Glider flew even better, with its thicker wing, elliptical dihedral wing (a radiused wing tip polyhedral, like that of the Eflite UMX Radian R/C motor glider: https://www.google.com/search?q=Efl...sclient=gws-wiz , might work equally well, while being easier to make), and below-the-chord-line leading edge. If you know of anyone in your area--or if there is anyone here on YORF--who does CNC machining of foam--or could 3D print molds for it, reproducing the NDC Super Glider in closed-cell foam, with the 1/4" dowel tail boom (and with a forward upper slot for an eject-able motor pod; its "Y-tail" [a pretty flat "V"-tail, with an underside vertical fin]) would be perfect for model rocket use, and:

Off the top of my head, I can't think of any really high-performance RTF boost-gliders (the RTF Cox Space Shuttle America's two parasite gliders flew much like the actual Space Shuttle Orbiters...but they looked sleek), and a "hand-toss-able *OR* rocket-launchable" NDC Super Glider would be a popular product. (Its rather hard-rubber nose could be made of the rubber-like "grades" of the Por-A-Kast or PolyTek resin, poured into a single-cavity RTV rubber mold--or a "multiple single cavity mold," to make ten or more at a time.)

I was going to o recommend R/CGroups of which I'm a long time member.
There is a plans business from the UK that presents free plans of most model aircraft.
You download them on your thumb device and bring it to a printing place.
I'll try to find it.
