It's just 2 bolts Scotty both the plate and Tuttle have male inserts that slide into the mast , very clever and solid as no flex or movement . Axis have a similar set up.

Oh no! Just as I was looking at the 2019 Slingshot Infinity, along comes this foil! And at a great price too.
Should be a great foil like Piros has said.
So now what do I do?
Hopefully someone will compare both for me to make the decision.
At this stage cheaper for me to get the Slingshot wing as it will fit my original H4 fuselarge.
But if this one excels might be worth saving the extra $400 for a whole new foil.
Hopefully the NP foil fittings will hold up. In my view it looks strong enough as it is bolted into the wing recess having the wing under the fuselarge to take up the forces.
Hey Piros! I need a comparison! Lol.

Seajuice after a year of testing everything this is the one . By far the fastest and smoothest in turns . The wings are super light and strong with a slightly higher aspect design , this is what is giving it its speed and glide. The extra width in the mast actually lets you lay on it in the turn and helps with stability paddling around. It's just a comfortable easy foil to ride. As I said in my previous post ignore Colas comments the connection points are super strong and the windfoil guys have put it through it paces for well over a year on metre long mast

nice review Piros, keep them coming as I'm starting to get a foil itch

So before you go passing dud judgements on other foils and post on a public forum , ride it or at least hold it .

I can say it because the 1st generation Gong foil (Hellvator) had basically the same fitting, and it worked fine also for Gong kitefoils for 3+ years (and other brands for longer). But with surf foils, this is not the same story, the wings are wider, with more leverage. So the 2nd generation went for a Go Foil-like fitting. The difference is night and day. You are talking of a leverage ratio of around 40/1 on the wings to the threads... forces are huge. Plus it levers against one corner of the fuz, whereas a GoFoil-like spread the forces against the 4 corners of the fuz/wing junction, and at the very least 10 times more length.

You can make these foils tight, but it needs applying a lot of torque to the screws, and some thread lock because as soon as the vibrations (something happening more with surf/SUP foils) make it slightly unscrew, it is back to the beach.

I is just a warning to my fellow customers, based on first hand experience and basic physics.

Anyways............?? What size does the large wing equate to Piros? Somewhere between the IWA and 200 by the look?
something halfway between the 280 and 200 be awesome for dwindling.

Pretty close to the IWA & Axis 920 Scotty.

There you go folks another in depth review & warning from a person that's never seen the foil.

Axis and Naish are two of the best surf foils out there and they seem to be doing alright? The forces are only enormous if you are running massive wings and even then it doesn't really matter, most of it is overengineered anyways. The pocket and fitment of the fuz to the wing are what takes the torsional force and with the foil below the fuz the bolts aren't doing much most of the time and even when they are it's in tension which bolts are supposed to do. The NP foil has titanium bolts if youre so worried about this?

Where do you get these numbers from? "40/1" sounds like you pulled that one out of your ass and I apologise if you didn't.
Take your gong ambassador bull**** somewhere else if all your gonna do is advertise

Simple. The wing is a lever:

basically, the tip of the wing is M2, the bolt is the fulcrum (blue triangle), and the contact to the fuz edge is M1.
I was speaking of b/a: b is the wing span (40cm), and a is the distance from the bolt hole edge to the fuz edge, 1cm I guess from the pics.

Note that an advantage of these directly-bolted-on systems is that they allow changing the angle of attack via washers, especially useful for the stab.

And if you actually read my post, I was praising Go Foil for coming up with its design on the 1st generation. And thus saying that Gong didnt get it right.

I apologise profusely as my statement didn't have enough legitimacy behind it to be posted to the internet without further research.

Thanks heaps Piros! I will get the large one as soon as possible. Just have to find a shop that is closest to Wollongong NSW that has them already in stock & low shipping fees. Hate having to wait more than a fortnight for delivery.
Understand what Colas says. More strength in fuselarge going into wing. But a good design with tight fittings lessens the chances of breakage like Piros has confirmed.
But more of a concern for breakage in my view are forces from totally different angles like a side on hit from a wave that is capable of bending a mast.
But hey. Just have to be careful with all foils.Time will tell.

Here is a couple of clips of the foil. We even have been dock starting with it which is pretty amazing for a wing that size . It's so incredibly efficient.

I'm loving my JP 7 x 28 board. Shed loads better than my converted Hokua

Got one on order. Thanks to my missus. Lol!?????????????

Took me a while to find the wing sizes in metric, so here they are for anyone interested.
Large 1612cm2
Medium 1225cm2
Small 1032cm2

I lined them up for a shot today , only just got the medium it's a nice ,right in between a Kai & IWA . My small hasn't arrived yet but I might not get it as the medium & Large will cover my bases.

What's the cost looking like just for a wing? Eg if u got the full large kit but wanted the medium wing a little later?

Extra wings are $400 so really well priced.

Definitely well priced. Thinking of getting a medium as well some time next year.
Just wondering what size wave the large wing would be able to handle fairly comfortably for a person like me at 80 kg give or take 2kg. Average height 5ft 10". I would imagine up to waist, but hoping shoulder high as well due to its stability & rear wing changes & settings.
My Slingshot H4 seems to handle up to head high. But I am comfortable on waves at waist to shoulder high. The instability of the H4 on take off makes me miss a few rides. But goes alright at the upper end of its speed.
But at my local lake entrance most times the waves are small & week that makes lifting & riding the H4 very difficult.

Where can I get some more info on the dedicated JP foilsup(s)?

How light or heavy is the NP foil compared to the 2018 and 2019 Naish foils?

Camarillo
Here is a link to the boards
http://jp-australia.com/2019/sup/products/hard-boards/2019-foil/
The foils are a bit lighter than Naish 2017 but not as light as the carbon mast Naish 2018.

Seajuice:- On my Sup I'll ride the large front wing with small rear in head high surf no worries . I never had a medium just small & large when I was riding the protos . I mainly used the small on the prone in anything over 2 foot as the large has an instant lift on the take off. Now there's a medium I'll be swapping that around a bit more. I'd definitely go the medium large combo.

You probably mean :The foils are a bit lighter than Naish 2018 but not as light as the carbon mast Naish 2019
The 7'0 seems to be the right size for me 7'0x28 115 liter... I have never foiled and paddle on a SB H29 112 literypernut 7'2x28 105 liter....
How about combining the 7'0 JP foil with 2018 Naish surf foil? What size foil should I get to learn to foil?
Or should I get a bigger board to learn to supfoil, like the Naish Hover 120 7'6x30 120 liter or the JP FoilSlate 7'8x29 112 liter?

You'll grow out of the the Naish Hover pretty quick but yes better to learn on. You'll be fine on the NP 7-0 plenty of float and foil really makes boards a lot more stable . Re the Naish wing definitely go the XL really nice wing overall and good for learning as well , get the quick release plate as well that thing is the bomb .

Thanks Piros. Well I just got my foil delivered yesterday. Well boxed for delivery. I sprayed all bolts with white lithium grease & put it all together to make sure nothing missing. All good.
The only problem I had was the bolts to connect the foil to my board because of the aligning wedges for board tail rocker. So had to use my thinner 6mm bolts that I used for my Slingshot.
So today attached it to my board with the large tail wing.
Surf was head high & quite powerful high volume waves breaking over a sandbar out off a lake entrance.
First wave I caught the Neilpryde surged forward & then like hitting a powerband it lifted with so much force I couldn't get it down within that second & bucked me off! I was sure then that I couldn't possibly fly this foil in these waves.
Then on my second & last wave I called it quits after getting bucked off again whilst trying the whitewash. Just wasn't worth risking foil & board damage especially with the thinner bolts I thought. So I resided to use it in much smaller surf which I expected anyway.
This foil has much more lift than my H4 which I was hoping.
Anyway will have to wait for a smaller day & will attach the small tail wing & try that.
And in the mean time order or find some longer 8mm bolts at 30 & 40mm long. The thick end of my wedge is is just over 15mm thick.
Oh. Don't throw away your old wetsuits. The legs make good wing & mast covers. And you can use the arms for tail wing covers too.

M8 bolts....got my longer ones from bunnings-as I was using a chunky end plate/shiv also. Get those torx head variety (as many have recommended on here) . Only about $6 for heaps of them

Thanks heaps stevet73. I looked at Bunnings online & couldn't find any bolts so will have to go & check.

My local Bunnings didn't have what I needed as it's one of the smaller ones. As long as it's the big warehouse style store, they should have a good selection....

Thanks mate. Will check Shellharbour store first.

Hi Seajuce, would you mind measuring the total length of the foil edge to edge frontwing to rearwing?
I want to compare that to my Slingsshot FSUP. Thnx in advance.
Alex

Hi AlexF.
514mm from the back trailing edge of the main wing to the back trailing edge of the large tail wing. Measured along the edge of fuselarge & would be pretty much the same along the centreline of fuselarge.

519mm to outer tip edge of tailwing.

Yeah. stevet73. Bunnings has them as security screws. They have the little pin in the centre of the torx insert. Lucky the supplied wrench has a pin hole in the end to fit. So all good.

I should have bought my bolts 5mm shorter as they do hit bottom of tracks & dig in by about 2mm. But seems OK.

I can get away with using 4 bolts at 35mm all round for my 15mm thick wedge. So only the two front bolts dig in. Lucky its a solid HD track block & not a stick on mount.
