Foiling NY's review of the 1300 is up, (obviously done last October), with some interesting conclusions. Faster than expected but low speed performance is not quite up to that of the 1150. The only wing thus far that is kept aloft by the second wake of the jetski (in the comments).

I appreciate the effort he takes in controlling the variables and presenting the information.

Agreed Jim,
I like his methodology. I can go back through past tests and compare. That little white buoy is always in the same place. And we weigh about the same. I think he's good enough at it now to show fairly small differences in gear.

The only variable I see is the amount of time he might spend on a setup really dialing it in before testing.

I never wanted for better performance last summer than my 1010/390 setup. I may try a 420 tail but don't see myself going black. Couldn't live with the increased stall speed and don't have any use for speeds over 20mph. 99% of my time riding waves downwind I'm going 6-15mph. If I was downwind racing I'd be much more interested but I'm in no hurry  :)

Where did the 5% come from?

Educated guess :)
The specs indicate the 1050 'should' out glide the 1010 (same stab). Properly loaded the 980 'should' out glide all three. I'm thinking 150# rider would be optimum, been through all this in paragliding. L/D should stay the same regardless of loading but doesn't work that way in the real world.

The vid shows the 1010 and 1050 to have identical glide distance in use.

I'm sure the 1150 will out glide the 1010 by a little at my loading. In this case it appears L/D may have increased on paper but I'm not seeing that in this video.

Hey Axis, if only it was possible to try this stuff before buying :)

Oh I haven't outgrown the "available" equipment. I'm just annoyed at the $2k gear currently in my garage and am not about to spend $2k per setup on new gear because it's 10% better.

If we're defining performance as purely lift/drag, we're only seeing increases of less than 5% over last years gear and that number will continue to shrink. Improved technique has the potential for far greater gains (at least in my case).
Foiling NY guy tested the A 1050, I didn't see any real world improvement and he's still preferring the 1150.

Did the measurements on the Gong Veloce XL and 430 V tail as per Admins method.

Front wing is set at .58, rear at 1.53 for a 2.11 dif

The L is probably a better comparison for size to something like the 980 but the XL is what I have.

Front wing 17mm thick, rear 6mm, volume 1.35L, area is 1520cm2 span 94cm
The large is like 15mm, rear 6mm, volume 0.95L, area is 1214cm2 (both projected but they're practically flat)

So these things are super thin and low volume as well as being trimmed pretty flat. Unfortunately I can only speculate how they work. I like the sort of mid-aspect ratio though. Think it will turn well and be pretty forgiving.

We are beta testers.

That's exactly what Airtime said  :)


My Ensis also exploded,before even touching the water.The version with windows, they lowered the inflation pressures after that.

Armstrong had to recall a run of AWings, they were self destroying too.

We are guinea pigs, although i expect this third gen gear to be much more reliable from all manufacturers.

I would expect better from this generation as well but I won't be the beta tester of new Gong wings again. A really good company would do what Armstrong and (more indirectly) Ensis did, acknowledge there was an issue. Sure, the wing was cheaper but after repairs it was significantly more than if I'd just bought a name brand from a dealer at full retail, plus I had the two lost days and swims. I don't wish those on anybody.

Next post will surely be from Colas defending the brand...

I'm perfectly happy with the vast majority of stuff I've purchased from Gong, even the 5m Pulse actually worked perfectly well.
With as many people as I've seen though having exactly the same issue, I'm guessing there was an issue...

Thanks Admin, I am going to try this in the near future with the new Gong stuff I haven't been able to even try yet. At least I can spend some quality time with it  ;D

Interesting stuff Admin, thanks! Haven't the tools to measure this.

Double Dacron to stop the exploding gong wings?  ;D

The original pulse also had double dacron somewhere in the LE. Having had a close look at the inside of the LE on both sides of my 5M (due to both sides exploding), it also may just have been where the LE meets the strut.

Mine exploded at the seam where the batten met the LE on both sides (two separate incidents). There was a reinforcing material along the seams which also tore. Someone here I think suggested a dull needle could be the culprit, tearing fabric fibers instead of piercing cleanly. Airtime reinforced it, I assume the new owner is happy enough. Wing worked well enough when it was inflated and it's always good to brush up on your self rescue technique  ::)

They 'look' a bit better than the last series, simpler at least.

Still curious if anyone happens to have their 980 in the same room as their dial calipers (assuming the calipers will reach that far back)...

What's the max thickness of the 980 foil section?

I'm at the back of the line (89/100) in this nifty site:

...I'm behind 19400 other folks in Hood River county (Isn't the population more like 14000ish?  :o )

It's a beautiful piece of kit Admin, it took some doing to not buy your 76mm (80's my minimum). I'll probably buy an 86cm eventually but because I have a carbon fetish, not so much for reduced drag. Interestingly enough, the Axis 96cm carbon mast pees off the trailing edge roughly the same amount as the alu version(s). Can't say how that correlates with drag but logic dictates... 
Here it is after polishing off a few liters of German pilsner  ;D

What about masts that pee like a fire hose, sucking water half way up the shaft, while other masts are silent with zero peeing.

Drag?

It "appears" to be worse when the mast angle to the water is more acute on the TE but it's there pretty much all the time on the Axis alu masts. This guy maxes out at about 12mph though. Started looking around and I see it on most brands, can't be a good thing. Here's a good view of it starting at about 1:22

I like Bill's "all the streamlining of a rooftop TV antenna being dragged through the water" analogy though  ;D

So do any of you industry guys have any idea when the 1050 will be available?

Diese neuen Wings sind speziell fr die Black Line Fuselage:
High Performance Speed Wings
Front Wing 1050 - HPS - Carbon 1050mm x 170mm / High Aspect (Dwight says 1460 cm2)
Front Wing 980 - HPS - Carbon 980mm x 160mm / High Aspect
Front Wing 930 - HPS - Carbon 930mm x 155mm / High Aspect
Front Wing 880 - HPS - Carbon 880mm x 150mm / High Aspect
Front Wing 700 - HPS - Carbon 700mm x 160mm / High Aspect
