I wonder how it compares with my current favorite of my own creations from January 2024. The S1 is very slightly higher aspect than mine and I have some different foil sections going down to the tips of mine. This foil and my foil are uncannily similar in plan view. It's not my fastest foil but it turns incredibly tightly and has a great low stall speed. I'll have to keep an eye out for new Armstrong riders with the S1 and try a swap to compare the ride. I don't see any magical anti breaching going on with mine but seeing as I recently made my own 850mm carbon fibre mast after being stuck on a 750 for a couple of months, I have a really nice 100mm safety zone for breaching now. In around 18 sessions on mine(1320 sqcm, 850 span), the worst I've had was to suck a pocket of air over the top surface, rode it down and then the increased speed and decreased loading ditched the air pocket and I rode up again. My older bigger foils I used to feel when the foil was close to breaching but when I did my 2022 second batch of designs, those ones dropped that warning but had incredible stall resilience. My 2024 batch, I've refined to increase speed a lot but still maintain some of my anti-stall technology. Armstrong are doing it now on at least one of their wing series (They call it Tip-twist from a USA design contributor) but there's no evidence of them doing it on their Step 1 wing so they are probably still debating whether to introduce it to their other wings. Almost all manufacturers will do it in the future, It started with Triton after I linked the aeroplane tech on kiteforums, then I think GoFoil with their mould ends chop and weld back at different angles, I find the design aspect really fun. People forget that a foil's volume displaces that much water and water's inertia is massively different than air. I suspect a lot of the computer fluid dynamic modelling people run is missing some really important points or we'd have hit more advanced wing shapes years ago.
The S1 1550 is quite a bit different to the HS1550 as it was developed this year and the HS 1550 was developed about 4 years ago. They have learned a lot since then. Key differences with the S1 are lower speed lift and lower stall speed. Better breach recovery. Auto leveling and it is hard to get the S1 to come out of the water when it is close to the surface. More stable and better tracking. Top speed is similar. HS1550 will turn better.
@@kippywylie That's exactly what I have started with and quickly dropped the CF 300 stab in favor of the HA 195. I'm now jibing very consistently but as a lighter rider 148 lbs when the wind gets over 16 kts I feel like a smaller 1550 would be better. I plan to keep my 1850 as a light wind weapon but have started looking at either the 1550 or new HA 780.
@@luksterp6049 I'm also 148 pounds and I purchased a 232 stab with a 60 cm fuselage. I'm intrigued by the MA 1250..... Or something smaller? Getting ahead of myself because I still need to get wet. Traveling now
Teasing that new Mid Length Armstrong board 👀
Also teasing that cwc v4 😊

Hi. Can you compare S1 2450 with CF 2400? Witch one is easier?
What Foil Size do you recommend for a beginner with a weight of 70 Kg? The 1550 or the 1850 from the S1 series? Thx
For a beginner, we are recommending the S1 1850 for a lot of riders. Will get you on foil easier and will be more stable than the 1550.
How does the S1 1550 compare with the HS 1550 V2 ...? Earlier lift but top end slower ?
Good question. After 10 years of kite foiling I've purchased a 2nd hand HS1850 for my starter winging foil.

Unrelated question but really like the look of the board you are riding. What is it and in what size please?
Matt, what board are you riding?
Prototype of a board that comes out next month. 🤫🤐
