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.
best regards,

David

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.
BR,

David

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.
