Apparently people using the large stabilizer and 84 wing are using the short fuselage. Have not tried it myself

Loving the big Infinity 84cm wing in C position with 48cm rear wing
Cranks upwind in 10 knots and huge fun powering S-turns cross/down-wind.

Angled the large rear wing with a washer to get a little extra lift.
Balance now seems perfect, at least in today's 8-12 knots - I think it will keep the nose up when riding waves too.
Got to fill that gap - it's a weed trap.


I reckon Slingshot have nailed the 3 wings - Infinity 84 & 76 and Time Code 68 are all equally awesome

It is confusing - the large 48cm rear wing is designed to mount on the bottom of the fuselage.

I don't think it would lift well if you had the wing tips pointing up like the smaller 42cm rear wing.

Mounting the rear wings as recommended ensures that the more curved wing surface faces down.

Tried the washer in the stabiliser as shown by azymuth
definitely gave more lift in 8 to 10
still not enough so will try 2 washers
checked a friend's 84 cm sup/ surf foil today
shim is slightly thicker
fuselage is much shorter
when in position c is about 2 cm further back than my switch fuse
keen to try both
will post results

I ordered a short fuselage for mine. Yet to try it though

Has anyone else with the 84 had trouble getting the front bolt of the two big bolts to screw in firmly? I had about 8 sessions on mine when I noticed that it wasn't tightening properly into the mast cap, I thought the issue was that the threads on the mast cap were stripped but when I threaded the bolt without the fuselage it threaded fine. I ended up taking a slightly longer bolt that came with my H2 wing and it threads fine, but sticks out of the bottom of the wing by about 2mm. It's more secure now than it ever was, but it's weird this started happening. BTW, the mast cap that came with my Infinity appears to be glued in place, and is not perfectly flush with the wing in fact it's angled forwards slightly which I would have thought if anything, would make this less likely to happen.

I am stoked with this wing I had it out in gusts to 28mph the other day with a 5.8 as the wind came up out of nowhere and it was still pretty well behaved all things considered.

Tried the extra washer in the stabiliser today in 8 to 11 knots
wow gets up early but still a bit too much back foot required
it would be brilliant for learning as so easy to control.
I will borrow a friend 's short fuselage and see how that goes next

Hi CAN17,

The mast cap on mine appears to be glued solidly into place, unlike the H2 where it is a separate plate. I have never seen any wobbling whatsoever with my wing, it is rock solid. Last night I put 20km on the wing with the slightly longer bolt from my H2 and it was perfectly fine. I'm now getting comfortable enough to really carve this wing on the swells downwind and it is so much, I am very pleased with this setup.

I think a lot of the drilling the extra hole came from SUP foiling were guys were running the mast in the A position and it seemed to wobble and create slop in the wing slot. Drilling the extra hole still is a good idea in my mind but you only get one chance to get it right, someone needs to come up with a template to lay on the wing so it becomes a sure thing.Oh and while they are at it make one for the 76.

I agree the 4th drilled hole that azymuth did might help in this case. A template would be a good as kdog said. But would probably throw out the warrenty.

I'm sure many have seen this video already. But it is Wyatt explaining the different infinity wings.


I found it interested when he was talking about how the wings create more down force the faster you go causing you to lean further back (like windsurfing). It helps you to not overfoil. Has anyone found this idea true? As it is contrary to what many find when foiling overpowered and having to lean forward more & pressure on the front foot.

I got the same experience with the 84. When using it the first time and accelerating in a gust, i prepared for getting lifted, but the wing just stayed settled. Amazing feature on the Infinity Wings.

I use the 84 with a short fuselage and the small rearwing, 70cm mast. Quite reactive but still manageable pitch control. Amazing manouverability, turns on a dime. Also easy to ride over chop since it reacts instantly on pitch adjustments.
But i'm foiling since 2016, maybe the reactivity is a little too demanding for a beginner.

I have had one session on the 84 with small fuselage and large stabilizer. One thing I did like was being able to recover overfoiling and prevent breaching much more easily. I was thinking at the time that slightly longer fuselage might be better, but perhaps with more sessions I will get comfortable with it.

However, I am kind of wondering if it is better to just stick with one foil (prob the 76) and adjust sail size according to wind speed. switching between different foil set ups seems like a vastly bigger change than rigging up or down.

I have both the long and short fuselage. I started with the short and liked it fine. For windfoiling I now only use the long one. I find it stabilizes the flight a bit and I can be a bit slower making height adjustments. It is just a bit more relaxed for me. I do not see any downside at this time. I use the 84 into quite strong wind although I keep meaning to try the 76 in windier conditions. I think this is because I am not interested in speed but rather just cruising with the least power and playing on swells.

Well I took the plunge and had 2 extra holes drilled and countersunk into my 78 cm switch fuse. From memory they are 50.92 mm apart from each other and the rear C hole. Don't take that as gospel. I had an engineering shop measure it properly and do the drilling. (Thanks Mark and Gordon at MWF Engineering at Thorneside)
.


I now have new positions D (one bolt in the rear C hole and one in the new hole)

Position "E" both bolts in the new holes but switch the fuse so the wing is in the B direction



And position "F" bolts in both holes and wing in C direction. I think this is unlikely to be used.




I have tried out the new position "D" with the 84 cm wing. Better lift and do not need the washers in the stabiliser anymore This would be an ideal position for a beginner on my board. I can get planing get both feet in the straps and a bit of a push on the back foot and up she comes nice and steady. It is still back foot dominate to fly but nowhere near the pressure of before. Controlling height is easy and no concerns with breaching. I can almost gybe and keep flying.

The front wing wing is between the front and rear straps but the centre of the wing is still rear of centre of the straps.

I am keen to try position E next.

Moved the 84 wing an inch further forward than C position (C+) without drilling more holes in the fuselage, by utilizing the mast plug holes.
Tapped the holes out and inserted helicoils to take 6mm hex bolts.
I wanted to use bigger bolts anyway as I was always rounding the original 4mm hex bolts.


Removed the washer from the rear wing. Filled the mast plug void in the wing with poly car filler.


The lift of the 84 wing seems about right now.
Allowing for the acceleration down swells which increases the lift to a point where I need all my weight on my front foot - I don't think I'd want the wing any further forward.


The adjustability of the Slingshot fuselage system is awesome to customize to your weight, sailing style and conditions

Tried the same set up today. Seems to be the goods when the wind held out.
