I took out my 84 wing in bigger waves than I probably should have. My session ended when I couldn't steer the foil properly on my last wave ... when I checked the wing, it was super loose and wobbly. The bolts had backed off maybe 3-4 turns. I was stoked to just get in without losing the foil. First time that's happened.

Next session I brought an allen key out, in case of needing to tighten them up again. After a few waves, I noticed some play/wobble in the wing, but when I checked it, the bolts were still tight. Inspecting it on the beach, the slot that the mast fits in seems to have widened by maybe 1mm, so the wing cannot tighten up solid in the slot. I confirmed it wasn't the mast by attaching a different wing, solid as a rock.

As a temporary repair, I put a piece of duct tape on either side of the mast, could just barely slide it into the slot, and it seems to be pretty solid. But that kind of half-a**ed duct tape repair is known as "Bojack" around here....is there a more elegant and permanent solution?

Anyone else experience this problem? Suggestions on fixes? EG could maybe attempt to add a layer of fibreglass to the inside of the wing's slot, but that looks to be a challenging repair to do well.

Aluminum insulation tape from Bunning's. It's basically a roll of self adhesive metal shims.
But obviously take it back to where you got it from?

I had a slingshot setup a while back. It was bad for that.

If it backs off during a sesh and you get involved in the shallows the lack of a recess in the fuse allows the the mast bolts to bend/potentially rip out of the mast base.

That happened to me and I lost my setup.

I'd advise the non permanent loctite and maybe a little bojack tape.

Thanks to you both.

I am not considering seeking a warranty return, as I doubt warranty covers this use scenario (though if Slingshot is reading this and offers, well, wouldn't refuse)

Aluminum insulation tape: pretty sure I know the stuff you mean, I have some I've used for dryer vents. (need the Canadian equivalent to Bunning's ;-)

Loctite: problem with loctite is I am using tefgel to avoid corrosion from dissimilar metals. However, I may give this a go, if the bolt issue continues -- as well as bringing an allen key out with me. Super mega sucks that you lost your setup!!! That gives me a sick feeling ... this dumb (but awesome) sport is already more expensive than I am comfortable with, that would be a gut punch with a crotch kick thrown in.

Keep us posted, I just got the same wing for windfoiling. It fit on pretty snug and I hope it stays that way.

Yes it was an expensive experience! In hindsight I would've gone a different route, but the new wings are nice and I liked the 76 I tried. The old wing construction was a bit of a joke....just so heavy, it would act as a perfect anchor in the impact zone.

i ended up on Gofoil and I'm happy with that!

With regards to tefgel and galvanic corrosion in foils...the threat is a bit overstated. More of an issue if the rig lives full time in water, as water is required for the process to really do it's thing. It is possible of course and you should break them down once in a while to clean but loctite more than likely will present a barrier between the face of the 2 metals anyway. Jerking the threads out of the fuse is a bigger worry unless you want to spend your sessions flipping you rig and tightening up!

I have a cheap Al foil that I treated by injecting plain old silicone sealant into. That worked great at holding the thread and stopping corrosion....bonus is that it blanked the chambers inside the mast reducing degradation of the inside of the mast over time too.

I got my mast and base plate used cheap because the prior owner welded them with seized bolts. So, overstated to a point maybe, until it's not! :-)
Less of an issue on my sup foil though, as I have to detach the fuselage after every use anyway. I got a kickass sprinter van to hold all my toys, and now this massive wing is too big to fit, LOL. But on my kite foil, I leave it attached months at a time ... so have to remember to detach and grease it up every once in a while.

Good tip on the loctite, will give it a go.

And congrats on graduating to the gofoil, those are sweet rigs indeed.

The reason I'm waiting for some Neil Pryde wings masts etc.
Time to update after 3rd summer on hoverglideslingshot
Great product at the time and price point excellent
Learned to foil on H5 then H2 kiting
Got a H4 after supfoiling start with H2 but found it to slow compared and am loving the h2 with mast behind the wing
Gonna keep kiting H5 for now as I tamed it by fairing the underwing concave to FLAT and now I can drop into large waves safely on 850 mast
There are flex and wear issues that you need to be able to manage
Easy if your handy and have the tools
Appreciate the experience but can't wait for new gear
Will sell 2 cheap setups to help others

After the o- rings on the stab hot tip the next one for me was to epoxy a fuselage into the H2 wing to finish with the hole wear
If you have mast to fuse flex, this movement is obviously bad and could lead to greater problems
Get a grinder or curved file and create a concave in the bottom of the mast cunningly so tightened New bolts can pinch the edge of the mast all around to the fuselage

Also to ensure a stronger mast fuse join i bought a thread tapper modified to go deeper up into bottom holes
Then longer stainless bolts with a good cranking up
Easy as bro and choice for long time

I've had a few Slingshot foil setups now, including the 84 infinity. Used for WindFoil and Sup Foil.
Firstly I always mounted the mast behind the 84 wing direct to fuselage with the M8 CSK bolts, this never seemed to be a problem in coming loose. I also used the aluminium mast cap in the front wing, having stripped several of the older plastic/brass ones. This lets you crank the M8 bolts tight. Also the M6 CSK at the back of the wing must be tight, and check for wear in the hole, as it can cause front wing to wobble. One option to really lock the front wing on to the Slingshot fuselage I have seen is to drill another countersunk hole in front of the three existing bolts on the underside of the wing (leading edge side). There is a spare threaded hole in the front of the ali fuselage you can bolt a M6 thread into. This then gives you four fixings to clamp the front wing tight. Otherwise try the ali tape option first and see how it goes..
Happy foiling!!

Just to be clear here. You are going to cover damage to foils caused by surf? Including people bailing in the impact zone and associated damage?

When I read through the warranty policy, it seemed too very closely resemble the industry standard warranty of workmanship and materials.

Above (from your quote) it could be taken that you are also covering consumers against damage caused by the surf too?

Is this correct?

JB

ps. not stiring shyte, just clarifying.

Thanks 7 Nation. I'll keep an eye on it, see if the shims and various suggestions work right, and if not perhaps consider it.
This is one of those tough ones, as I feel like I pushed it beyond its normal limits, in bigger surf than it's designed for. But on the other hand, the flaw it has now results from its design, with the mast sticking into the slot and that connector facing massive and repeated side to side forces. How many uses is that connection designed to withstand, in reasonable limits? Could the connection be improved and would a discussion with SS be useful in confirming this need? (eg a bolt could be placed horizontally through it, would the added strength be worth the extra weight?) Dunno!

Btw, I am in Canada ... I just join in this australian forum because it's the best one around.

Anyone notice sling shot 2018 gear on sale but they have bumped up the rrp price? Case in point, 2018 h4 is 'on sale' at $1300 and the rrp listed as $1700. I bought mine for $1350 a year ago and that was rrp at the time. Am I way off or has slingshot doing a dodgy?

If I'm wrong, sincere apologies. If not, don't think that will encourage my loyalty to them....

Looks like the rrp for the "new" construction wings on the old heavy ones.

Hi Juandesooka.
I have the old H4 set up but havent really checked the mast & wing connections. But I believe the issue you are talking about isnt really the elongated hole of the wing that the mast fits through but would be the main hole of the wing that the fuselarge fits into may be too big making a sloppy fit. That is, I would put the fuselarge into the hole of the wing & without bolts connected is it a sloppy fit, can the wing be wobbled? Compare it with your other wings.
If so then maybe an internal shim or whatever may have to be put inside the hole of the wing or maybe Slingshot's newer fuselarges could be slightly thicker?
If not . Then it probably & most likely is your old mast threaded holes.
If the bolts are tight then they may be too long & hitting the bottom of the mast threaded holes or the bottom of the holes could be blocked or burred or have corrosion NOT enabling the bolts to tighten down far enough to clamp the new wing down tight. Don't forget. The old & new wings may be different thicknesses at the holes.
In this case your options would be to get slightly shorter main bolts or re tap the threads further into the mast if possible. You may have to drill the holes a little further. reason for this is that the bolts & mast have been used on the old wings so the bolts have only tightened down a set distance leaving the ends of the threaded holes to maybe corrode or burr over time.
So this may be the reason that the bolts came loose in the first place as it is the under side head of the bolts that have to clamp down & bite into the wing. That's why spring washers were invented to bite between the mating surfaces in high vibration parts to stop bolts loosening.
Your bolt heads may have only touched the wing as they couldn't be screwed down far enough to bite in.
Hope you know what I mean.

Hey JB

Yeh our warranty covers manufacturer defects. If the product doesn't perform how it's intended too. IE. to surf waves, and breaks during normal surf conditions, then it should be covered by warranty..

Obvs if someone damages the foil on purpose; running it over with car, then no.

Not sure what's this has to do with anything in this post stevet73 ?

Good catch anyway.

Those 2018 H4 foils were supposed to be on sale for $999, just like the H2 foils. Price has been fixed now. Looks like it pulled the original pricing from the current model sku

Slingshot related thread. Thought it more polite to put here than draw attention with a new thread heading.

Your welcome....

@ stevet73:
Maybe we should further discuss prices here and keep this thread technical.

Didn't want to discuss prices. Just wanted to clarify a pricing error....which is now fixed up.....

Happy foiling!!

I've been very interested in the slingshot windfoil with the infinity 84 wing. I've never heard of this problem, until now. Since windfoilers use the mast in positions behind the wing only...would this mean your ok then. Since the OP had the mast above the wing.

I'm not too familiar with the slingshot fuse to wing mounting system...I assume that 2 of the 3 bolts thread threw the fuse and then into that mast cap and one just goes into the fuse...please correct me if I'm wrong. I Didn't realize there was a plastic w/bronze threaded mast cap (was this only on the 2018s)... I thought they were all aluminum.

I use the Infinity 84 for windfoiling and have not had any problems with the mast to fuselage connection and have not had the bolts come loose. The Infinity wings come with the aluminum insert not the plastic one. My older h4 wing had the the plastic one. I bolt the mast to the fuselage not through the wing. I did try it once but found in had much less lift that way for me.

Update on this.....slingshot USA warrantied it. Pretty stoked with the customer service! Thanks for suggesting it 7 nation.

surf today tomorrow! Now with the h2 / 84 combo I am ready for a whatever comes my way. Yew!

Great news. But I am wondering what was replaced & or fixed? And what was the actual cause?
Also wondering if the problems have arisen from adapting the 2019 wings with older parts.
Either way. Great to hear Slingshot warrantied the problem. After all it wasn't your intention to damage their product.
Good on them.
Have fun!

I also had IMMEDIATE and very satisfactory response from SLINGSHOT on a Infinity 76 Warranty claim...THANX SLINGSHOT!!
Took a few pictures and explained what happened and they didnt even blink...just sent out a new one.

By the way, the first wing that delammed felt a bit "wobby" with the fuse ...maybe like yours?? The new wing they sent me was MUCH tighter with the same fuse...actually, had to knock it in a bit with a rubber mallet (like GoFOIL users have to use)....

Been foiling for 3 years and Im TOTALLY STOKED on my new monster 76 wing...besides opening my horizons to pumping and carving tiny swell going downwind....I can get out and ride with a 10meter Airush Ultra in 10 to 11 knots...and i weigh 95 kilos wet with harness!....its a great product for the price...already paid for itself in amazing sunset sessions.....

and as an ADDED bonus (you get the Ginsing Steak knife absolutely free....) the thing is REALLY EASIER to use in SEAWEED infested caribbean waters than all the other foils ive ridden! I dont know if its the profile, the thickness, the fact that you can kite super slow or 22 knots, the fact that I can bring her all the way up to breach and just skim along the surface like a flat stone, without falling (which usually knocks the persistant clingy weeds off) or WHAT but the INFINITY is really turning out to be a session SAVER on those days when the Sargazo Slalom is threateniing to ruin the day.

Id love to hear any reviews from you guys who have ridden the Infinity back to back with the Ghost whisper 91 (Moses 633) as far as TOP END is concerned...that could maybe compare the "weed shedding" properties of each.

Good Winds!
