Went out today with SS 84 in position "C", standard stab, 90 cm mast. Wind 10-12 knots, sail Ezzy Elite 6.8, board JP foil 155. My weight 88kg.
Perfectly balanced, two hours of unhurried bliss, not worrying about high speed injuries I often get on a race foil
It does feel quite a bit slower than 76, but I pushed it to 18 knots at times. Never breached out. For me position C seems perfect.

The 84 is phenomenal foil (76 is quick and 68 is a high wind maestro)...
foiled tonight in super flukey 8-18+ mph with a 5.0 (JP 135) and it fly's through holes like nothing else and I'm 92 kilos, have yet to foil anything else like it.
I'm looking to buy a JP 135 and a slingshot 76 do just for light wind stuff do they work ok together?
I'm 80 kilo and bin windsurfing 35 + years.

I have the setup mentioned. If your worried about how the slingshot deep tuttle head fits into the JP 135 don't be because it fits amazing. It is a match made in heaven
.
I've only had two runs on it. But can say it has much better lift, stability and a lower stall speed then my old foil( NP alu blue). And much more front foot weighted which I like . Just get the board in the air and it is not very difficult to keep it there. It's very forgiving and doesn't like to breach. Would like to give a better review when I get more TOW/TOF.

You could buy a smaller board - the Infinity 76 doesn't need that much width.
I'm really not getting on with the Infinity 84 as it so back footed even in the C position. The 76 and 65 wings are great on my Wizard 103 but the 84 is much harder to gybe because of all the back foot pressure. I've probably got 70% of my weight on the rear foot and if a gust hits I can't stop the board hitting the water.
I bought the wing to learn how to 360 but I get much closer on the Infinity 76.
After having trouble with the 42cm stabiliser I bought the large 48cm rear stabiliser hoping that would help. But it makes the balance even more back footed (yes, I do have it installed with the tips down). Does anyone know if there's a difference between the surf and windsurf shims?

wetndryboardsports.com/quickshop/index/view/path/foil_!_foil-parts_!_slingshot-hover-glide-rear-wing-shim-kite-wind-2020.html
I'm wondering if the surf shim puts the rear stabiliser at a different angle.
The next step is to drill some more holes in the fuselage as mention above to give me D and E positions.
That's weird Simon. Have you tried running your mast in the full rearward position? How about your footstraps further back? I have the 84 with a Wizard 125, I run it in c position with the mast foot typically fully aft or close to it and I have not had this problem. Perhaps a D position is the call as you suggest.

Take a look at your leading edge of your 48 stab. They had a few with a little too much sanding on the leading edge, which caused the leading edge to crack. The extra drag would hold you down even a lot of rear foot pressure and with the c position.

Good idea. I'll try the mast foot further back but I don't really want to change the footstrap positions as I often change wings. I like to be pretty front footed and the current footstrap positions give me that with the Infinity 76. With the Infinity 65 I'm really front footed - almost too much.

There's no crack in the leading edge of the 48 cm stab but it's very sharply defined unlike any other wing or stabiliser I've seen from Slingshot or Lokefoil. The one side of the leading edge is nicely rounded but the side nearest the fuse has a very hard edge - more like the trailing edge on most wings / stabs. Does yours look like that?

I believe the surf and windsurf shims are the same. Yes you don't want to be moving the straps when you change wings. I guess one suggestion would be to have the straps set up so the track is forward for the 76 and 65 and then move the track back for the 84. I had this issue on my freestyle 115, where I needed an unridable amount of back foot pressure to make the 99 work. One solution would have been to move my straps back and move where I position the foil mast (more backward) for the 76/65.
I got the 84cm front wing together with the 42cm rear wing. I am a total beginner to foiling. Is that not an ideal match then? I see several of you refer to using the 84cm front wing with the larger 48cm rear wing. What does that really make of difference? And is it worth the money for me to get the 48cm already to start out with then, if difference is significant?
I am a very experienced windsurfer down to small home built sinker boards at 70 liters.
A fairly lightweight at 70 kilos. Bought the Levitator 150 board and that slingshot infinity 84cm foil to get started foiling this year. (and still waiting to get out there and try it first time...). Expecting to use sails in 5-6 m2 sizes. Dont wont to use bigger sails than that, but hope still this will suffice to go flying in lightish wind conditions, all considering my low body weight and large foil wing.

Hi Cyber. I would say you made the right choice. The large rear stabilizer is primarily for surf and sup foil and is meant to be used on the short fuselage, which I would argue is no good for windsurfing.
However, some people use the larger rear stabilizer on the long fuse, and some windsurf with the short fuse. I have tried both and do not like either.

Hi sl55, you said you went out with : "SS 84 in position "C", standard stab, 90 cm mast. Wind 10-12 knots, sail Ezzy Elite 6.8, board JP foil 155. My weight 88kg.".
As my weight is 70kg, would then say I could do the same with a smaller sail, like just a 6 m2 sail?
Or is windfoiling not the same in this regard as traditional windsurfing?
Aka I take normally a sail 1 m2 smaller on the same day as my friends weighing 15-20 kg more than I do.
And do the position that you should put the fuselage of the SlingShot Infinity also depend on your weight, or is it all down to which board you use and the placement of your footstraps and the foil fin base underneath? I understand its like the front of the main foil wing should ideally be in the mid point between your two legs, for you to enable an equal (balanced) weight distribution between your two legs for when you fly?

No, Using a radius gauge I measured about a 1/32 inch radius. I wonder if your picture shows fine line due to the lighting?

It's not the lighting. When I first picked up the wing to check the leading edge I thought I was looking at the trailing edge!

It does look like a trailing edge but this is the leading edge. The trailing edge is much narrower as you would expect. I've never seen a leading edge like this.
Is your leading edge rounded without a well defined line?
Here's some pictures from a different angle:

My first generation Lok?foil (2016 Envol) had wings which looked like that, to be honest, back then I didnt really have much of a problem with it. The next gen Lok? wings which were more rounded were faster, but with the older wings I didnt have any cavitation or stuff like that. Don't think that is your problem although I'd still check whether its right ;).
I like the 48 stabilizer for the 84, it's a heck of a lot more stable when the wind gets gusty or picks up, really controls breaching for me. If you're doing well with the 42, don't rock the boat, but if you're breaching a lot in gusty conditions, you may want to look at the 48.

Good to know, I guess the large stabilizer resist the lift of the front wing.
You using the long fuse?
Hey guys,
Very interesting thread.
I bought the the NP RS:One foil back in 2018 (price was just unbeatable) and sailed about 6-7 times with it that summer, with my SB Formula 147 and a 7.3 2 cams sail (North S-type). Although I had some fun and did a couple of nice flights, in general, I had issues to stay up ; I just felt that the foil lacked of lift for the 10-12 knots range I was trying to sail in most of the time. I was surprised I could bring the board into planing without the foil even lifting the board at all ; If the wind was app. 15 knot ish, I could even windudsurf / plane normally (but a little bit slow due to the full foil and board drag)
So basically I needed to pump on the a plane. And then even pump further to lift (with max pressure on back foot) ... My conclusion is that this foil needs a lot of speed to get up, and it's not a light wind solution. 12 knots is seemed the minimum range, even when pumping. ( I weigh 170 lbs)
In the end, I felt like I lost about 2 knots (or maybe even 3) vs my formula setup and 9.8 sail.So I gave up.... and did mountain biking last summer.
But now I see that new/better wings came out on the market, in particular the Slingshot infinity 84, which has a very large surface area ( 2066 cm2). That's much more than my RS:One foil which has a surface of app 850 cm2 (rough guess since NP does not seem populate this spec) . This should make a huge difference. It looks like you guys have been trying the SS infinity 84 . How do you think it compares with the NP RS:One ? How many knots would I gain on the low end (with pumping).
At 170 Lbs, do you think could I get easily going in 10 knots ? Is a 7.3 sail m2 sail worth it, or 5.8 m2 would be enough ?
Do you think a formula board would work relatively well with this foil (i.e Wing in position C) ? The middle of the back foot strap aligned with the front screw of the tuttle box. So a little bit further forward than on the wizard 125 (for which the deep tuttle box seems direclty aligned with the back foot strap)
What about the the Infinity 99 ? Is it worth it for a relatively light guy ?
I am assuming that the inifnity 76 is a good option, but not the best for light wind. In any case, if could buy it later if this wing is much better for 15-20 knots.
There is also a used Horu Vini pro XLW foil available for sale in my area. How do you think it compares with the SS I84 for light wind ?
Thanks in advance for your advice,
Max.
See Cyber's chart and table for sail size and windrange.

I started on a Neil Pryde pinkie, and after researching on this forum, bought a i84/gamma 68 package. The i84 is so different to the pinkie. I have it in C position, normally with 7.0 Severne Foil Glide, I am 185lb.
It floats up on the foil before getting to planing speed, (sometimes need to slightly pump the foil), then accelerates. Much greater windrange than the pinkie, though is slower but that's fine for learning. I can get the i84 up in maybe 10-11 knots, and not yet a good pumper, it gets a bit breachy in winds above 18knots with the 7.0 sail.
Have only tried the gamma once in 18-25knots, was too lazy to change the fuse to B position, so it breached a lot when it gusted, but was much faster than i84.
I don't get many 18-25 days, when it does get that strong, am keen to try the gamma in B position and the pinkie again.
As you are lighter at 70kgs, maybe the i76 is better, would also try with 5.8 sail first.
Lots of reviews of both i76 and i84 on this forum.
Have fun.
@ Oscarddog : Do you have the I76 as well, or just the 84 ? I am looking for someone having both to make a comparison. According to Slingshot, the 84 covers 1 knot more on the low end.
170Lbs actually equals to 77kg... So I am afraid that the I76t is a little too small light wind.
Can you enjoy the 84 up to app. 20 knots of wind ? Or does it become a pain to ride beyond 15 knots ?
What do you think should be my next sail down after 5.8 ? Do you think I can go down to 4.7 , or is 5.2 relevant ?
Max.

First, yes, the 76 and 84 will give you much more bottom end. I think your current foil is maybe 800-850cm2? These are 2-2.5 times that. In the meantime, I'm mystified that you are having so much trouble with it. If you are wanting to tweak it in the meantime, post where you have the mast base, boom height, foot straps, etc. If the board is planing, that foil should lift off at your weight, I'd think.
The Horue XLW is 979cm2. It's a very good lightwind option but the much bigger Slingshots will be easier to get off the water. The walk to and from the water on the other hand... The Horue is significantly lighter. The Horue LW is probably equivalent to your current wing. At 160, I could easily foil the XLW in 8-9 knots with a 7 something. The Slingshots are a more stable ride, though.
If the budget allows, the Moses 790 is similar (very similar) to the i76 but better quality, imho. It's also available as a Gaastra foil.
Hi
Thanks Paducah. Well the RS:one foil works, but it requires so much speed to lift.... In the meantime, read a few other post on the forum which said the same thing. In general, this foil lacks of lift (small wing) and is very back foot heavy. Not really a light wind option. And fuselage is on the short side.
So I will change for a Moses or a Slingshot.The big question is which wing(s) should I get.
The 790/I76 or the 873/I84... or both.
Any thoughts ?

I am not really qualified to give advice because I am still learning.... but I opted for the i99 and the i84, and I plan to buy the i76 too. I also have the SS FWind 1 (which I think is the 65 or 68?), but I've never used it. I think for beginners the i99 and i84 are valuable and useful. At least that's my feelings.
I probably use the i84 the most right now.

I have or had all 4 infinity wings. If you are a big dude I would get the 84 (unless you plan to get the 99 in the future). But if you are a regular dude, who knows how to pump the sail, I would recommend the 76 as it has the largest wind range of all the infinitys (IMHO). Yes you will miss some of the early planning of the 84, but this means you need to schlog a little further to the wind-line or wait a bit more for the wind to come up.
I personally don't feel the slight early foiling of the 84 offsets the loss of maximum speed relative to the 76, unless you live in a chronic lightwind area (meaning your smallest sail for windsurfing is 7.0), but If you want to push the light wind envelope you should probably get the 99 (99 and 76 is a great combo), but the 99 needs a board with tracks.
Hello,
perhaps I can give you some feedback, in 2018 I start windfoiling with the H5 position C and my falcon 148L with a combat 5,7 and was able to foil around 12-14kts with a big pumping and my 74kg. The combo need king of kick on the tail to tack off.
Winter 2018-2019 I get the I76 and with the same board and my S-type 7,8 I was foiling with 8-10kts foil in position C.
the big help is the falcon capacity to creat speed and a lot of volume in the back of the board. Only point to be aware of is this combo feel to power full for the foil and give the feeling of twisting the mast if I go to fast from reaching to upwind for example.
on side of this I started foiling with the wizard 105, that was another world but on light wind the pumping is more difficult with the short length with a super session 6,0 and I76 position B I foiling at 10-12kts.
to improve the low end I get end of last year the I84 and the rear wing 48.
I ride it once on the 105, 4,2 ice rear wing 42 and position B wind was just limit to get me water start really smooth but back foot feeling.
in January I try the I84 c position and rear wing 48 with the falcon and S-type 7,8. wind at start was around 8kts with some pumping I was able to foil but the balance was not the best as the mast plate was to forward using the 107cm slingshot reference. Due to the falcon fin box position I need to be at least 2cm more back to avoid the board to fly nose down and help the foil take off less kick on the tail to start the fly.
As soon I can get back on the water I really want to try the combo wizard 105 , I84 position C rear wing 49 and the supersession 6,0 that should get me flying around 10kts, for lower I need to get better to pump the board or go on the 125 to have extra length.
if you keep your formula I will start with the I76 in C position it will work better, my feeling is that the I84 will give you not that big plus on this kind of board and if the wind pick up a bit you will play a lot more on the I76 as board and sail will give you a lot of power and the I84 will not be the best to accept it.
the I84 is great on the 105 that allow to use really small sail for a smooth ride
