I am not going fast at all, but I am going faster with the 1125 than the 1250/1550/1850. I'm just above the 30 kph.

In my experience the higher the aspect ratio the less surface area you need to make the foil work.




Depends on what you mean by "making the foil work" and your power source to lift the foil. I get that everyone is super excited about a new foil and direction for Armstrong but facts are stubborn things.

Despite people's individual reports, the fact remains that higher AR (for a given SA) means higher stall speed. May not matter if you have a wave pushing you but for winging, going up on AR requires more wind/wing (for a given SA) to achieve lift off.

For those who like to repeat the canard that SA does not matter for high aspect foils, sorry but the laws of physics have not been canceled.



i think there are aspects of foil performance that can't be captured based on two specs like AR and SA. There is also the practical application/sensation of foiling w/ all these other inefficiencies. but I've had different foils from different foil brands that have similar outlines and specs that ride completely differently with different wind/speed ranges. the two ~AR10 foils I've used have been surprisingly easy to get going and both had glide unexperienced with other foils I've used.

For my W1000, I don't know if there's a huge difference in takeoff ability b/w the 790, 950, and 1000, but I would have to do side by side by side test. My Fanatic 1750 and 1500 get going earlier and more easily (at least I believe this to be the case).

I was expecting the SAB W950 and Fanatic HA 1500 to perform similarly, but they are totally different and both very nice.

Geez that foil can glide!
Rode it today again in about 20 kts.
Feels like I had about double the time through each gybe to complete the transition...
Felt like it needs more attention than the other HS foils though - it rewards "good form" so to speak...
It's a cracker...

Any updates from HA1125 riders? How does it compare with HS1550V2? What setup? fuse 50 or 60, tail V200 or 232 or 212??

Ok, it looks tasty

Agree with this. Not so good in waves bigger than waist high or turning when going fast.

I've been supping mine for a while now and at 102kg i am loving it. Fast with heaps of glide. Turns plenty good enough for me. handles waves over head high easy

I haven't felt overpowered yet it just goes faster and I haven't found the top end speed yet.

it carries enough speed and glide to cross a trough and ride a new swell in front with barely a pump

It easily glides on tiny bumps when up
to speedRiding it with the std 232 tail plus1 shim 50 fuse
its an absolute gem. only thing I'm not too keen on is the knife point shape -makes me nervous and I don't want to fall on it!

I gave the 1125 it's maiden voyage today! 100cm mast / 70 cm fuse / 13" kdmaui tail / +1 shim 4M wing in 14-20mph wing with flat water transitioning to thigh high river bumps in 80 feet of water. A+ barrel nut worked just fine with the 70 fuse.

My A+ 60 fuse didn't arrive (sold my old 60) and my 50 fuse wouldn't fit at the beach, but luckily I had packed my 70. I hadn't ridden the 70 fuse in over a year.

This foil is awesome. Finally seeing the light when de-powering into a wind bump and not feeling like I was on the verge of loosing speed quickly if I didn't take the perfect line. Even with the mega-mast burying the foil deep, I was connecting my longest downwind glides yet. I hated the 70 fuse though.

Made probably 80% of gybes compared to 98% on the 1250. Made my two toeside tack attempts (touched down on one).

I didn't get to push the speed too much as the flat water area had lighter wind and the longer fuse had me less confident. Upwind performance was unreal.

The stall speed looks around 7-9 mph based on gps. Launch speed is very similar in the 6-7 mph range. Definitely pumped to get on foil more than I have in a long while and I certainly worked out the soreness from yesterday's COVID vaccine! Really needed a strong gust while moving forward to get up. My mast positioning, strap location, and tail shim choice were probably not helping. Will need some dialing in (also going to experiment with baseplate shimming to help with back leg fatigue).

I will check back in after I get out on the 60 or 50 fuse with the new tail wing.

First time on a HA wing and I was kinda nervous feeling it out. It was really pretty easy and straight forward however. Gybing and turning required good form (no lazyness on the first session). I only had to jump off once on a cutback on a bump one where things felt sideslippy or weird in some way.

Initial thoughts: this will be my go-to river/ocean bump riding foil and down-winger foil, as well as summer flat surf pump wing. It also felt like it wanted to jump as it flew upwind!


Nice detailed initial impressions. Any more info with more experience?

Well I tried the 1125 for myself and was astounded at the glide and pump and surprisingly good carve. I have used a bunch of higher aspect foils from Lift and Axis and the 1125 is head and shoulders better than any of them. (in my experience and opinion.....calm down). Compared to the 1250, the 1125 has a noticeably higher stall speed and doesn't turn as well but it glides twice as far. Today was small but when you get on a thigh high wind swell and manage to keep the foil high, the 1125 just gets so much drive out of it, it almost feels like a motor kicks in. It must be the acceleration.

The biggest downside is the higher stall speed. I needed to go up one wing size. You also have to keep your speed up a bit during transitions but that adjustment was easy. I first used the V tail (no shim) and found it EXTREMELY pitch sensitive. The 232 was much better and didn't seem to give up much glide. That set up turned much better than expected and better than the Axis foils in the AR=7 range I have used.

70 kg rider, 20 mph avg winds. Ensis 4.5 wing, 75 L custom board, 85 cm mast and 60 cm A+ fuse.

I'm glad I'm not the only one who found it extremely pitch sensitive with the V200 tail!

With the 232 & +1 shim on the new A+ fuselage it handled great - for my intermediate level...

A lot of this will be personal preference but for people like me who need to grow into being comfortable with such a "technical" foil, no shim is the best starting point.

I found the 1125 and v200 with no shim on the A+ fuselage to be insanely twitchy!
but that's probably just me.

seems running the 1* shim has settled things down a bit.

having said that - I like the v200, +1 shim and HS1850 combo for light wind, the glide & pump is amazing.

I'd really, really love to see a larger surface area HA foil from Armie.hint.hint.

I was having the same twitchy experience riding prone on the 1125 , then I slide the mast to the back of the tracks as suggested by Sky Rama and yeehaa so much more control now it's amazing.I thought I would lose some pump but even that was better because I have so much more control. I was struggling with it ,but now I'm really enjoying what it can do , amazing pump speed and glide.1125/72/50/v200 +1 shim.

To me - too sensitive particularly in pitch and to a lesser extent in roll.
I can ride it but it takes a large amount of focus through transitions etc.
Again that's obviously my personal observation - I guess an expert rider looks for these handling characteristics to increase performance...?

So when you say pitch is it pitching upwards (hence you some adding + shims, and moving mast further back ? Because if she's dropping on you I'd say you'd want to go the other way and go more minus on the shims (although that doesn't seem possible at the moment with the A plus system).

1125/232/+1/60 fuselage : my ideal HA setup for winging...

For me the 1125/200 no shim was very twitchy in the sense that it was extremely pitch sensitive. Felt very much like I was riding my monofoil. I switched to the 232 no shim in the same session and all the pitch sensitivity went away. 60 cm A+ fuse.

The more I wing with the 1125, the more amazed I am at how good it is. I can carve it better than the 1250 and the glide and pump are orders of magnitude better than any other foil I have used. (Delta, Lift HA, Axis HA) I am mostly on 20-25 kt wind swell and it is effortless to pump forward to the next swell. I am a very mediocre pumper but just a few light taps with my front leg is all it takes.

Seems...from observation...hi aspect foils could use a slightly bigger stabilizer than recommended for ease of riding.
Seems...stab reco size is based on either expert wing foilers or racer windfoilers with long stabs and heavy sails.

I came to the same conclusion. Am playing around with various higher span stabilisers on the HA1125 to calm it down a bit for winging. FWIW Armstrong , Axis and Naish have the same bolt spacing in their stabs (35mm) so that opens up quite a few options. And the fact that they don't always mate so well with the front curve of the TTF doesn't seem to particularly matter at the lowish speeds we are doing , there's no appreciable downsides (vibration, noise or drag) as far as I can tell. The purists might disagree but that's what I have found out by just trying different options. I just use a long barrel nut and bolt combo to bolt through the fuse, mostly use the 0deg TTF and it all works fine. Note that I'm winging , not proning.

Was on the 1125 today with -2 shim (reverse the +1 & trim- Thanks Hilly), Used 60 A+ fuse with 232 tail. Winds were 18-25 knots, wind swell. Worked great, pumping is stellar. Better than 1250 for pumping, although the 1250 is easier to ride and surf
