Hi guys,

I have just received the sweetest looking Foil I have seen so far: a 2400 Armstrong Foil for Wingfoiling. I am now thinking about getting a smaller one to go with my Exocet Freefoil 132. Right now I am using a Slingshot Foil with Infinity 76 and I am very happy. None the less, the foil is limited and the build quality of the aluminium foil is nowhere near a carbon-foil. As I am 95kg and mainly foiling due to our low-wind area, a carbon foil is on the list.

Is there anyone who has some first-hand experience with the Armstrong foils on a windsurfer? The goal would be a 1550 with the 70cm fuselage and a 95cm mast.

Best regards,

David

Does Armstrong have a windsurf fuselage?

short fuselages are not great for windsurfing. Carbon looks cool, but unless super stiff, nothing gained. I saw the tech sheet for Slingshots new carbon mast. They claim its the stiffest mast in the industry. Pretty tech

Do you recall any of these specs?

Was there any spec on the thickness or the width of the mast?

This is a big deal on the longer masts. ( Drag while turning, craving )

In my personal opinion SlingShot has a way of hyping things up without much technical information. This is why I ask as I have seen very little as far as tech sheets on any of their products.

Thanks for answering,

sure, carbon is not the answer to all the questions. But the aluminium parts are pretty limited. The Slingshot foil is not only heavy, the connection between the mast and the fuselage is a pretty poor design. The fuselage-mast connection of the Armstrong foil is a pretty clever thing. The longest fuselage they offer is 70cm, where the long Slingshot fuselage is 60cm, so I can't see the problem here first hand.

Slingshots long fuse is 71cm. With the infinity 76 wing the distance between the two wings from tip to tip is 100cm. Which is a good size for freeriding, I definitely wouldn't want anything shorter than that. For larger sails and racing longer definitely helps.

tip to tip? What is the standard way of measuring a fuselage? Depends more on how the winds are mounted surely? Leading edge to leading edge from front to back would be useful. Unless you do an approximation to centre of lift (1/3rd back?) to allow for low profile front wings

With the front wing attached to the fuse its 100cm. Sorry for the confusion. Found the specs in the windsurf mag.
www.google.ca/url?sa=t&source=web&rct=j&url=https://www.windsurf.co.uk/test/slingshot-hoverglide-fwind-wizard-125-2019-test-review/&ved=2ahUKEwjJx6KGxqnlAhX9IDQIHScEBagQFjAFegQIAhAB&usg=AOvVaw0BuarHl1c-D2DLCQ8UmOuu

I agree there should be some consistancy/clarity with how manufacturers tell people the fuseledge length. They should say total length of fuse with wings mounted, of course this changes with different wings and depending on brands. But it seems most just tell you the length of the fuse without wings attached when you buy a foil.

Hi,

if I got it right, the long fuselage is even 78cm, so it is 8cm longer than the Armstrong one. But the fuselage length ist not the only possibility to tweak the stability of the foil. Another thing is that different profiles/airfoils and aspect-ratio have a big impact on the performance, so a given length of a fuselage is only a number.

Really no one that has tried an Armstrong foil in a windsurfer?

G'day,

I just found a windfall dedicated fuselage from Armstrong foils, which is not listed on their website, but at realwatersports.com. The TCW80 is 80cm long and moves the front-wing forward by 2 or 3 inch I guess.

Awhile back I had a chat with Army Armstrong about his foils for wind foiling and he said he'd need to test the position of the wing and fuselage. That was awhile ago and I'm not sure if anything has moved forward on the wind foiling front since then?

Hi StevO,

well I just received the windfoil-fuselage from Armstrong. I will give it a shot with the big 2400 wing in light winds. If that is any good, I will order a HS1550 foil.

How did you make out with the Armstrong foil setup? My son has some for kiting and loves it. If it works well for windfoiling it might make sense to build out foils and bits in the same system. Thanks

super shovel shark killer

I was also wondering about the Armstrong Foil for windsurfing. I currently have a Naish WS1 which is about 1200cm and seems too small for our super light winds and boat chop on US East Coast. I would be curious to hear how that 1600 Armstrong is, otherwise I might go for the Slingshot 76 or 84. Board is Naish Hover. Thanks for any insight

Effective measurement for fuze length would be COE to COE.

I just bought a SS Infinity 76 for use on my Naish Hover 122. I was using the WS1 and was pretty proficient on it. I've been foiling for not quite two years and I'm 140 LBS. The normal position fort this wing SS is position B, middle position on the fuselage. This is how I set it up and I put it all the way back in the track. I had to have my weight too far forward to use the foot-straps. I did not bring the bolts to the beach which would have allowed me to try position A, so I took off the front foot straps. I kept the back one's to use as a kind of stomp pad. After a little getting used to, I liked this set up very much. I think strapless is the way to go given my style of foiling, more downwind and swell riding orientation. Still, I could drive it upwind very comfortably without straps. This foil has much more lift and stability than the WS1. As I said, I was quite comfortable on the WS1, but the SS Infinity 76 was a game changer for me. It has a significantly longer fuselage and wing width. This makes the ride more stable but does not seem to hamper the turning ability at all. The ability to keep on foil at much slower speeds allows more room for error on jibes while still staying on foil. The ability to go slower also helps to stay in the sweet spot on the swell to avoid nosediving or foiling out. I'm not that into speed, but when I try to push the speed limit on the SS-76 I feel much more stable than on the WS1. It comes with a 90cm mast which also makes things easier than the standard 70cm mast for the WS1. I also have the 71cm mast for the SS which I've use in some of our shallower spots. I've been out about 10 times on everything from 2.8 to 4.7 conditions. The only downsize as far as I am concerned is the weight. A bit hard for this 67 year old body to carry to the water, but not a deal breaker. I don't know if setting in position A would you to use the foot straps on the Hover or if that positions changes the characteristics of the ride at all.

Also, I am very interested in any input from someone who has tried the Armstrong foils for windsurfing. I bet they'd be sweet. I'll be needing something lighter for my old age.

How was your experience with Armstrong foil for Windsurfing? I am heavy set and also considering to use CF2400 with 85 cm mast and short fuselage 60 cm. I was told that 70 cm becomes very difficult to turn since the foil is very big.

A foil is a foil.
The only thing you need to watch is to center the front wing's coe to between your feet.
Every foil works.

My experience was not the same in regards to foil. I had difficulty with earlier versions of a Slingshot foil but with infinity, I made much better progress. I also used LP foil that use tuttle box and compatible for foil ready boards but I did not have the same experience of ease like infinity. Therefore, I would appreciate comment from DB2 with his/her experience.

A balanced foil works.
Just because YOU cannot make it work doesn't mean someone else needs to follow your example.
Maybe your foil wasn't "balanced"?

A mate sold his Armstrong when the front wing started to wobble, there is no fix for a worn fuselage to wing connection.

70 cm fuselage is short, will be very sensitive to rider input with a 1100 cm2 wing but may be different with that huge 2400 cm2 wing, gotta love AFS wings, they are solid carbon, as is fuselage, so could repair if needed.

Hi guys - going back to this thread. I have the SS Infinity 76 and 84, and ride them on an SS 115 Freestyle. Curious about anyone using the Armstrong foils for wind, and any feedback. Looking for something lighter, stiffer, and with a better mechanical connection than the SS.

Mast apparently is stiff. Will accept all Moses surf wings (W1100, new 9500 and 7200). There will be windfoiling and wing foiling wings (fuselages) as well.

I had been using i84 and i99 but decided to get an Armstrong foil due to its reported very light weight and good performance on wingfoiling. I will be getting mine in a week and looking forward to testing. As far as my search, there is no youtube video for Armstrong foils to decide for windsurf foiling. I got a message from someone who had used CF2400 wing but he was not pleased with the drag and switched to HS1850 and very pleased with it. Therefore, I also purchased HS1850 with the 80 cm fuselage as that is recommended for windsurfing but I will also try for wingfoiling.
Since I am a heavy rider (220 lbs), I primarily use i99 and if HS1850 does not perform on light wind conditions, I may also get CF2400 despite the drag.

I finally received my 1850 Armstrong with 85 mast and 80 fuselage/HS232. I have been so far primarily using Slingshot 84 and 99 so far but I wanted a lighter carbon foil set-up for my levitator 160 lt. I was able go out today gusting 15-20 mph range and used Goya 6.3 m fringe X. My runs were similar to what I experienced with infinity foil and very satisfied with its performance. Since it is a medium aspect foil it felt a little faster than i99. Taking the screws on the track is not easy each time. I hope they find a some practical solution like Naish system. I am still not able to foil jibe so I could not comment on that. Since the surface area is in between i76 and i84, it will not perform like i99 for lifting on low wind days. I am considering to get CF2400/300 backwing so I could go out on 10-15 mph days since my weight is 220 lbs.

Here's one nice solution for having to put the track screws in and out. They're redesigned so the screws stay in the track and you just put the nuts on top of your foil track mount and tighten with a spanner.

AFAIK the Australian dealer is out of stock but you can get them sent from the US if you don't mind paying US $25 for air freight.

Just put two strips of closed cell soft foam in the bottom of the tracks, this holds the plates in position but allows them to be moved if required. Then it is just a matter of putting the foil on the board and installing the screws, no alignment needed.
