Early on, right after the '29 came out I pulled a set of templates off one so could transplant the new airfoil onto my '27. Lo and behold there was no meaningful difference. I wonder when the change mentioned was implemented.

ASW27 and V2 have a wing profile from mid 90's. ASG29 has basically modified tips, which naturally have to follow the original profile.

V3 has 2 decades more worth of aerodynamical knowledge in it's design. One can speculate how much has happened during last 20 years but at least there is a great chance that something has.

Performance increase from one generation to next tends to be small but noticeable, otherwise you wouldn't design and build new gliders. For SH, all it takes is glider buying pilots believe that it will be better than 29. There are lot of pilots who tend to stick with one factory product and they surely have jumped already in que for V3.

One thing that bothers me is (6ft5') the fact that SH still sticks with fuselage built for dwarfs in a age when average size of people is something else. Would you buy new 200k glider with too big fuselage, knowing that similar glider with too small fuselage is better? Other one is FES blades sticking in the wind. The system is great, but when aiming to world's podium it just isn't the way to go. Unless they manage to fair the blades in some way (should be doable).

I think another big 27 to 29 difference is the ability to fly at a higher wing loading.
And let me clarify about the "Boy Band" reasoning, I don't expect a dramatic jump in performance from the V3. Improvement just doesn't work this way at the top level of the sport. I highly suspect the V3 will be incrementally better that its predecessor in all areas (Climb, Cruise, Handling, Rigging, Etc.). For a top level racing pilot this could make a difference on the scoreboard and for most of the the sport level pilots (Like myself) we could care a less about making the 29 or the JS1 their bitch on race day.

True, the 29 is 10 years old. But it also has been dominant thru this moment. Remember, the JS-1 gang did enormous research as well to beat the 29. Result, almost even performance. The JS-1 looks beautiful and exotic...but it's hard to surpass the 29.

I think without a dramatically major technical breakthru, any V3 improvements will be almost impercievable (especially at amateur levels). Designing a glider (or a racing sailboat, car, etc) is all about making the right proportions of design compromise. Every change (even highly modeled changes in similators, etc) has the potential to be better, equal or worse! The V3 has gambled that leaning further towards run performance and therefore less towards climb performance (and probably weak weather, survival slow conditions).

A lot is riding on this new airfoil and until very recently, no real performance data exists...

No real manufacturing innovation has been introduced with the C3. Autoclaved pre-impregnated preg carbon for example.

The V3s world dominance is simply not a given...

I look forward to seeing it...but I really look forward to seeing it fly in a wide range of conditions (minus the hype). If it's unstoppable, great. But I am highly sceptical that it will be."dominant." It may be great in certain conditions... We shall see.

The V3 is going to be the best glider ever built and everyone who can even just barely afford one should buy one(or two.) Pilots need to stop trash talking new gliders, the more new gliders pilots buy the better the used market. I need pilots to buy V3s now so there are lots of cheap V3s in thirty years. Don't forget if you are ordering a V3 get a nice trailer too. lolz

If the new Ventus was a real leap why did they stick the wings on the a
fuselage and not the c fuselage?

Glad I've got my deposit down for DG's new LS12 :-)

I'm waiting for the glut of doggy old 29's that will be coming on the market. I'll be first in line to snap one up. Sell Schempp, sell!

I am at the convention....No V3!!!!!

"I am at the convention....No V3!!!!!"

Given the date of first flight, there was no way it was getting to the convention in that time frame. Not unless they were stumping up the cash to put it on a vodka burner.

Anything interesting to report from Christoph Wannemacher's presentation on "Design Philosophy for the New Ventus" e.g information on the aspect ratio, aerofoil, wing thickness, transition position, turbulators etc?
