What were the origional PNF and TWF slopers.

I was looking at the "How will I know it's you???" thread and noticed a photo with an old R&R Nova in it.

Well, that got me thinking - What were the first pointy nose and twisty wing slopers?

First pointy nose sloper I can think of was the Nova. No clue as to what was the first twisty type sloper. Photos if you've got 'em.

I'd like to make a special mention that we wouldn't have the acronym PNF if it weren't for Brian Laird (TFLG), who claimed a few years ago that the Northern California slopers had a Pointy Nose Fetish. From there, we have since developed the TWF acronym to help define our twisty-wing-obsessed brethren.

Just wanted to get some history in here and throw a shout out to TFLG for one of his many contributions to the world of sloping.

Sitar special - yep - pointy!
And the reason was - not to be fast (as people thought), but to land on/into snow covered alpine slopes - just dork it into the snow! (or so I'm told - I've found it also works with a fairly pointy Sagitta Project Two & long grass or soft mud (!)
Twisty wing - Sailplanes international "Axle" (?) in the late 1970s ?

Earliest European TWF's I remember where the AXEL (French 100") and the SI AXLE (60" I think) from about 1980.

VS Sailplanes TWF

I first saw Ken Stuhr's VS line of TWF at Eagle butte during the '89 Nats held in Tri-Cities, Wa. They had been around for a while, and he was selling kits there at the slope. I bought a bunch of stuff and still have some squirrelled away for later.

There was also an all-molded 55" wingeron plane called the GP 100 that was really sweet. I got to meet the designer, I don't recall his name. He had some sort of machined hardware to make his wings twist.

Interesting to note is that the rere Kestrel would never have been if Tom Feldvebel would have been able to obtain a Rotor kit to build. Tom wanted a TWF really bad, and missed the boat on VS's production lifecycle. So, he designed the Kestrel, a T-tailed pitcheron.

The Sailplanes International Axle was one of the first TWF planes I was aware of. The design dates back to the late 70's. Also, Jerry Bridgeman's Snipe was available in the early 80's. There was German design that Wilshire Model Center carried in the mid 80's called the "Spiral". The CR and VS designs all came much later.

I think the Axle was one of the first if not the first TWF, unless someone knows of an earlier design.

I remember the GP Ultra from the World Soaring Jamboree in 93(?) or 94(?). The fellow's name was George, probably George P. Why didn't you buy one doc? I wanted one so bad but had no money...

I did own a German wingeron around 1973. Can't remember what it was called, but it had 2-meter span, balsa-sheeted styrofoam wing, a fiberglass fuse, full-flying stab, and rudder.

Makes me wonder what kind of servos you used in 1978 to articulate 160" wings
