I assume that the wings bend and a lot of lifiting power gets lost. Try to Analyse the under water situation by using a GoPro or such. Great video. Love to see part 2
That was my thought as well. Given how thin they are, when put under the load of a full person they probably just deform to the point that there is no lift
When I've seen commercial foils, they were VERY stiff - all solid CF and resin. I think the 3D print / wrap approach is not rigid enough Maybe 3d print a new one with room for a truss rod?
Great project ! Your main wing looks quite small, I do kitefoiling and the typical front wings are around 800cm2. Then the wingfoilers use bigger wings like 1000 to 1800cm2. I think you should try at least a 1000cm2 front wing with a 300cm2 rear wing for it to lift you over ;)
I always look forward to your videos. You're not afraid to show the development process and the failures along the way. Keep up the great work and you'll hit a million subs before you know it!
The foil sticking into the bottom of the board was hilarious! I think you need much much bigger wings. Also wings with a lower aspect ratio will make them stronger and more stable at lower speeds. Look at winging boards for inspiration.
Not necessarily, since the plastic box was above the foil mast, it was preventing him from getting his weight back, also higher aspect wings are usually better at everything that isnt carving + yaw
I really like your video style and how you show your mistakes and your trial and error, and you have great dedication. Edit: Is it possible to put jets on and have water cooling run trough the foil in to the board?
What I like about this video is you present even the fails as a fabricator and designer myself I have come up with all kinds of ideas that in theory should work but it takes me forever to perfect and get them working the way they are intended so kudos to you for providing the video footage because people need to understand the amount of work it takes to get a CustomDesign working correctly
You probably could have gotten it to work but you have the battery components blocking you from standing over the foils. My suggestion, for simplicity, is to add a footstop behind the battery and controller compartment. That way you can balance your weight over the foil. I don't think you have quite enough power to stand in front of the foil at this point. Maybe not even standing over it but worth a shot. Good luck. Can't wait to see your next steps and future projects.
That’s what I was thinking. What would happen if he left the foil as in bud shifted the weight back. One foot behind the electronics box and one in front.
Most commonly the center of mass should be directly above the front wing. Now the back foot is roughly above the front wing. It really seems that there is some lift coming from the foil. Just try to stand like Charles suggested and the board/foil should rise from the water. If not, then you check the angle/size of your front wing. Nice work, keep going!
so in windfoiling you usually mount a bigger wing if there are just lightwind conditions. Once you mounted the wing and probably rigged a bigger sail you might wanna pump the board out of the water. What do we learn? Mount a bigger wing and pump.
Love the creative ways of putting on the wetsuit. I've been following all the jet-boards with great interest. Hopefully I can make one of my own one day. As an old guy who is 65, I can relate to issues getting it up. You're young and will definitely get it up the next time. The idea of using 3-d printed parts as a shape to fiberglass over is brilliant and should be real useful.
Like this guy, no messing about. 1:06 into the video and the board is half built. Other channels will still be padding out the intro/greetings for 2 minutes. the missing satisfying moment tho
I love how you just iterate past things that don't work the first time. The little editing cuts are hilarious. Since I have no skills I can only suggest some Velcro in the electronics enclosure to keep things from sliding around. Oh and maybe a gasket for the lid. Keep creating!
I have also a foil but electric and i think that you just need a bigger motor or bigger wing, is just not enough lift, if he leaned back more it would lift but the wing would stall immediately i have like 30h on a electric foil so i know a little bit
@@henryknowacki3554Yeah I agree stall or un-natural flight angle on the front wing could also happen instead of flight. Definitely more speed could help too no matter wing surface area. However, these are all things worth trying but stance would be an easy test before tedious fabrication.
As a foiler myself all you need to do is move the mast forward which will create more lift. And only a small movement which be very effective. You'll also want to adjust this setting quite a bit so make it adjustable. Great effort by the way, love it 👍
I tried basically the same project last year except I thought the board building from xps would be too time consuming so I just bought a cheap board from my local decathlon. Also did some research and found Ray Velinga' s videos explaining the hydrofoil calculations. he also has a book its a great read, it would help you a lot. One other difference between your design and mine is that I used two aluminium box section to strengthen the 1 m long spar, İt works great. now Im building a much stronger v2 cause the first one broke on the board-spar joint while testing.(on sea with me on it while my dad was pulling me with a boat. which was terrifying to say the least)
big 3d prints like that really need some kind of extra strength, either box or threaded rod tightened down a bit like re-bar in concrete - I find thinking of 3d prints like concrete is good for the design process
@@trif55 Very nice analogy. When talking about pla I pretty much always use concrete as an example, cuz pla is stronger on compression then tension especially if the print lines are perpendicular to the force. Also its stronger than some materials like abs but not as flexible.
So many of these kind of projects on youtube are flexing by making it look easy and like ti worked first time. It's so great to see the iterative process. As for what I'd recommend: A bigger front wing will mean more lift, at the cost of a lower top speed. Looks like you're right on the edge of breaking free.
you can check out actual foils for windsurfing boards to see how they do it(shape and size). i'd recommend windsurfing ones because those carry the most amount of weight(bigger board and a heavy rigg so a lot of weight)
I built my own hydrofoil through Clearwater foils and things I noticed with that is once you make it out of the water you lose all you surface tension/drag meaning you can go slower once you break free. Also make the wing thicker for more lift…
Great work mate! A couple of thoughts: 1. The lift created by the hydrofoil is proportional to the size of the wing and the angle of attack of the wing. See if you can design a few different airfoil sizes and add a method to adjust the angle of attack and test them. 2. You may need to make the connection between the board and mast stronger. When the board is out of the water your entire weight will need to be supported by that joint. Consider doing a test on land where you attach the mast to something solid and then stand on the board. If it doesn't break, you're good.
A couple other comments point to the biggest issue with your wing and not generating enough lift. In layman's terms, with a higher aspect wing (wider in width and narrower in height), more speed is required to generate equal lift, than that of a stubbier style wing. When you pick up speed you can clearly see the board trying hard, but there is just not enough surface area to make it for the max speed you can get up to. When you go to a higher aspect wing, you will increase your drag significantly, but the trade off is you will able to be get the board up an foiling! Foiling SUP downwind setups which are popular would be a solid place to start given the length and weight of your board, or some of the larger efoils, like getfoil! Great video as always my man!
I'm a windsurfer from Germany. I'm pretty shure, that you need a bigger front wing. (maybe out of carbon)? You are really fast, so fast enough to get up. Also your Board is really long. The Foil Boards in Windsurfing are a lot shorter and wider. Then the board ist also pushing more water down. And maybe you need to shape your nose a little more like a windsurfboard. But so far, great job. Be careful, if you're getting it and the Board ist lifting it will be very unstable. And if its lifting to much, the foil will get out of the water und dann you will crash very hard.
Yes, to improve your receiver from getting wet is to put it in the balloon and Some silicone and some zip ties keep the water from getting into your receiver
check the flexibility of the wings, i suspect that they are bending giving you a different lift capacity than what it has been modelled for. Also a taller mast will give you easier lift, så perhaps the wing you have is modelled for no flex and tall mast, so you will need more power through speed to get equivalent lift. you can also make some cutouts at the back of the board reducing the trailing edge and thereby drag. Last thing, you might be able to get it to lift with some "pumping" but then you might just break parts. Great build though! and great storytelling of the challenges!
Awesome idea and nice to see how far you already got with this. I did laugh a bit at that first design, still surprised the wing itself didnt break even in the second design. I think the wing is deforming from all the upward force it is receiving, you may need a slightly stiffer wing even. Edit: ah i’m not the first person who noticed. 😅
Laughing out loud when the fuselage drove itself into the board! haha I find that when using a store bought e-foil sometimes you have to place your foot on top of the mast in order to make it lift. this is exactly where your electronics box is...
As a profesional foil windsurfer here are some advices. You need bigger wings, you need to make wings out of carbon fiber, you need to redesign the wings coz these ones suck. Try more aerodynamic fuselage. And play with the angles of the wings
Great build! Way to persevere. One thing which you might know, is that adding extra wall thickness when slicing has a much larger effect on strength and stiffness of 3D printed parts vs adding infill. It's why hollow structures can be very strong while reducing weight. Love what you are doing. I watch it with my kids. Best regards.
I've really got to admire your persistence and your dedication and getting the job done and how quickly you can change your wetsuit laughing good job good job great video it works need done on the design but you know that kudos
Great stuff. Couple of suggestions. It's all weight shift when controling the foil. So stand above the front wing. Do quick rocking from front pressure to rear pressure and back to front foot pressure to get flying. Much easier to do on a shorter board and with a flat deck. One foot either side of mast is essential.
I was looking at 3D printed wings for a while and was worried about them breaking. Happy to see it works and now I know I can use a 3D printed one too.
That's badass, from that first video I saw of a Hawaiian guy riding an unpowered hydrofoil board-I instantly knew that eventually powered hydrofoil boards were going to be awesome. I even tried to get my friend who builds aftermarket high performance wave runners and jet skis to build a prototype. Awesome work on all that 3d printing and building, I look forward to the next one.
You definitely need a bigger wing. The wing you used is designed for kitefoiling. There the kite lifts you additionally so the kitefoilers can use smaller wings. Nice video and greetings from Germany
Nice work. Back foot should be placed directly above mast. So you need to be much further back. Maybe bigger foil. Stiffness of all parts it’s important too. Speed looks good.
Foiler here. You need a larger wing. Like 2x the size. The larger the wing the less speed you need to get flying. Double it and try again, also need the surfaces to be baby smooth. Nice work so far!
Keep up the good work. The mast the wing is mounted to may be flexing forward from the thrust pressure. You may need a brace going from the front side of the motor mount diagonally (45 degrees) up to the bottom of the surf board further up towards the middle of the board (front to back).
My suggestions: Place your center of gravity above your front wing. Cover all of your printed part with thick layers of carbon fiber, especially in mast connections . With glass you are way too flex. Seal better your battery box. Keep your speed controller as cool as you can. I'm really impressed that you get that fast with this setup. Looking forward for your follow-on video. Keep it up.good luck
Really i think you should do 2 major things to be able to fly properly: one is to make a bigger wingspan front and back wings, therefore creating way more lift. (you will be a little slower once you're up there, but won't make much of a difference.. youll still be fast as f) the second thing was quite obvious: to be able to put your feet further back on the board. this means you have to move the electronics somewhere else, or you could maybe dig down a bit deeper in the foam and put them there. (they'll still be under your feet, but just not in yr way anymore. and add some grip tape or wax! cool vid tho
Hey, nice video I would say try to increase the angle of attack of the front foil If that does not work scale up the foils a notch and then play around with the trim Just a guess but it is worth a shot
That’s awesome. I’m always waiting for another video of yours. Truly an inspiration to keep myself of the bed and start working on a project. Keep it coming💪🏽🙏🏽
Several ppl pointed out two main possible issues: bending of the foils and the box impeding you to stand back enough. First I'd check foils bending and the effect of your body position on the board, I'd go for "static dry tests": block the front foil on a support and back foil under a support, get on the board to see how foils bent in order to keep you up. No need to go "full scale" like airplane wings' stress test yet you'll get an idea of what's going on and hot to adjust. For the foils you might use some Carbon Fiber PLA for higher rigidity + spars. You could make the mast thinner as well with spars inside and reduce drag.
Great video! For your 3D printed foil, make it stronger by adding 2-3 layers of carbon fiber fabric/cloth or even fiberglass fabric/cloth (do not use fiberglass mat). Carbon fiber has way better mechanical properties (stiffness, rigidity, etc) . You can use an epoxy resin for that, the best resins for technical carbon parts are: epoxies and polyurethanes. Search online, you'll find a lot of details about this topic. Also, I am not an expert on hydrofoils but you probable need a bigger foil and more thrust on your motor/propeller. Good luck buddy!
I think it's the flexibility of the wings. When you get up to speed the wings bend up past the point were they would provide the lift required. It's similar to porpoising in F1 where the downforce applies itself to the car, then after a certain point it squeezes the car down too much and puts the car at an angle where you get lower downforce, only in your case you don't have ground effect so there's no shifting in lifting force that bounces you off the board. Could also be that you're not going fast enough, so if you're not able to go faster you should make larger (*and* more rigid) wings.
Looks like plenty of speed, general rule is start with back foot over the mast and fine tune from there. I tried standing way forward of a 2000 size foil and couldn't get it to lift in powerful waves.
you could also watercool the ESC by drilling a small hole or channel through the mast, the water pressure from moving forward will push the water to, then one outlet and you have water cooling. have done this on rc boats. Cool Project!!
🤣 amazing work! 3D printed parts for DIY projects are genius! I also printed the whole gears and motor mounts of my e-mountainboard (8085 motors with a peak power of about 8kW) with nylon materials and a normal A8 printer - worked also perfectly!!! Maybe nylon would be a better material for your wings (little bit more flexible but stronger) maybe make them bigger for more buoyancy.
Great video! It seems you need more lift from the hydrofil. You may try changing the hydorfoil form a classical wing-tail configuration to a wing-canard configuration. A wing-canard will provide more lift while ensuring stability. Other than that, increaseing speed, increasing the main wing area on the hydofoil or tilting the main hydrofoil wing so the angle of attack of the main wing will increase may lead to generating some extra lift. Hope to see your progress in the next video!
That's a high wing loading (per area). Tiny flaws in shape, surface and angle of attack get magnified making it easy to lose laminar. More cowbell (area) needed on the wing. Some good comments on balance as well. For your "watertight" boxes, at some point you may want to suck it up and buy a plastic tote and some grommets. I know you like huge 3d prints, but.... It's good to see you back to having fun with the videos. I hope you're feeling better and enjoy continuing to inspire.
This is good work. in my experience (I ride a windfoil) there are a few things that will happen to you :) As soon as you start to rise above the water, the foil mast will break, because, as I saw in the video, it is printed on a printer and the layers are located across the mast. Loads on a mast - lateral. Therefore, it is better to replace it with an aluminum profile (a mast for a kite) or make it from carbon fiber. You also have insufficient rigidity of the aircraft. It is also better not to be made of plastic. Alternatively, plastic can be laminated with carbon fiber or fiberglass. Well, the front fender needs more. about 1000 mm2. You don't have enough lifting power to rise above the water. But you are great. Good luck!
in your cuurent standing position u had to much leverage on the foil. to start foiling you need or the stand farther back or to take the foil forward, or go faster to get more lift. the farther forward u stand in relation to the foil u will have more leverage on it(less lift) so or stand farther back or go faster. im a doing windsurf with hydrofoil board (windfoil) so i know a lot about it from experience, if u want id love to help u with this project by sharing ideas. id actually love to see u foil with a home made setup !
I assume that the wings bend and a lot of lifiting power gets lost. Try to Analyse the under water situation by using a GoPro or such. Great video. Love to see part 2
Bump
That was my thought as well. Given how thin they are, when put under the load of a full person they probably just deform to the point that there is no lift
i thought so too
When I've seen commercial foils, they were VERY stiff - all solid CF and resin. I think the 3D print / wrap approach is not rigid enough Maybe 3d print a new one with room for a truss rod?
Or maybe good ideas from people that have created successful boards.
I just want to say that I love the humor laced throughout your builds as you run through the trial and error process.
The presenting and editing makes it such a joy to watch! Nice job Simon!
Chaotic Evil editing at it's finest

Correct. If his body weight is too far forward on the board, the foil will never lift him.
Yup you need your weight centered over the lifting wing. Can't believe he didn't consider that fact when building this.
@@capodad2u has to be a lil in front of quarter chord to maintain stability, But at his speeds the wing is too small, he needs more power

My gut feeling, is that the box is in the way, so he can't stand back any more. Something to consider for future designs I guess.
yeah he needs to be able to stand in such a way that his center of gravity is a fulcrum for the wing

Your speed is fast enough to go up, but your wing is too small. Really impressive to see that the 3D printed mast resists with your second prototype 👌
Either the wing is too small, or it flex too much under pressure. I would recommend a full carbon piece.
@@AlexLefevreArt it's both
I agree it is both.... but for sure the wing is to small and maybe the wrong shape for lift under load in the water.

@@moite2665 if the structure scales properly then sure. windsurf foils are the perfect size though so they'll definitely work
Your delivery of lines and editing is the best. Always makes me smile.
I built my own hydrofoil through Clearwater foils and things I noticed with that is once you make it out of the water you lose all you surface tension/drag meaning you can go slower once you break free. Also make the wing thicker for more lift…
Dude, I've watched you vids for the begining... and your voice has not just CRACKED... it has BROKEN IN HALF
Great work mate!
A couple of thoughts:
1. The lift created by the hydrofoil is proportional to the size of the wing and the angle of attack of the wing.
See if you can design a few different airfoil sizes and add a method to adjust the angle of attack and test them.
2. You may need to make the connection between the board and mast stronger. When the board is out of the water your entire weight will need to be supported by that joint.
Consider doing a test on land where you attach the mast to something solid and then stand on the board. If it doesn't break, you're good.
I love the shed man that looks really cool
I'm amazed that the larger hydrofoil mast survived without being glassed. Great job on those new print settings! 👍

Your an inspiration mate. Keep it up.
After watching your videos, I am always willing to buy a 3D printer and start creating, but watching your videos is just too relaxing!
Perhaps changing the incidence on the wings could help? Also I think you're right that lighter (and maybe stiffer) wings would be necessary.
Yes, to improve your receiver from getting wet is to put it in the balloon and Some silicone and some zip ties keep the water from getting into your receiver

Honestly great that you were able to go that fast. Bigger wing and I bet it will rise
That's badass, from that first video I saw of a Hawaiian guy riding an unpowered hydrofoil board-I instantly knew that eventually powered hydrofoil boards were going to be awesome. I even tried to get my friend who builds aftermarket high performance wave runners and jet skis to build a prototype. Awesome work on all that 3d printing and building, I look forward to the next one.
You should make an underwater jetpack that goes on your back and propels you underwater.
You definitely need a bigger wing. The wing you used is designed for kitefoiling. There the kite lifts you additionally so the kitefoilers can use smaller wings. Nice video and greetings from Germany
ilmao
i love your videos i think people appreciate your success as well as your failures its good to know we are not alone,very entertaining
Nice work. Back foot should be placed directly above mast. So you need to be much further back. Maybe bigger foil. Stiffness of all parts it’s important too. Speed looks good.
amazing project! Well done, tough endurance to make it working !!!
I think it's all in your technique when switching into the wet suit. It's just not fast enough. Fortsätt göra fantastiska videor!
Foiler here. You need a larger wing. Like 2x the size. The larger the wing the less speed you need to get flying. Double it and try again, also need the surfaces to be baby smooth. Nice work so far!
Keep up the good work. The mast the wing is mounted to may be flexing forward from the thrust pressure. You may need a brace going from the front side of the motor mount diagonally (45 degrees) up to the bottom of the surf board further up towards the middle of the board (front to back).
My suggestions:
Place your center of gravity above your front wing.
Cover all of your printed part with thick layers of carbon fiber, especially in mast connections . With glass you are way too flex.
Seal better your battery box.
Keep your speed controller as cool as you can.
I'm really impressed that you get that fast with this setup.
Looking forward for your follow-on video.
Keep it up.good luck
Nicely done!! You are very skilled! I like that you are more humble than other RUclipsrs and don’t try to oversplain sh#t…
There's something so funny about you painting the board and idk why
Very entertaining video showing warts and all. Know you will keep trying till you get it. Thanks so much.
Really i think you should do 2 major things to be able to fly properly:
one is to make a bigger wingspan front and back wings, therefore creating way more lift. (you will be a little slower once you're up there, but won't make much of a difference.. youll still be fast as f)
the second thing was quite obvious: to be able to put your feet further back on the board. this means you have to move the electronics somewhere else, or you could maybe dig down a bit deeper in the foam and put them there. (they'll still be under your feet, but just not in yr way anymore.
and add some grip tape or wax!
cool vid tho
Hey, nice video
I would say try to increase the angle of attack of the front foil
If that does not work scale up the foils a notch and then play around with the trim
Just a guess but it is worth a shot
Respect on the determination and execution, hope to see more
That’s awesome. I’m always waiting for another video of yours. Truly an inspiration to keep myself of the bed and start working on a project. Keep it coming💪🏽🙏🏽
Several ppl pointed out two main possible issues: bending of the foils and the box impeding you to stand back enough.
First I'd check foils bending and the effect of your body position on the board, I'd go for "static dry tests": block the front foil on a support and back foil under a support, get on the board to see how foils bent in order to keep you up. No need to go "full scale" like airplane wings' stress test yet you'll get an idea of what's going on and hot to adjust.
For the foils you might use some Carbon Fiber PLA for higher rigidity + spars. You could make the mast thinner as well with spars inside and reduce drag.
wow i didn't expect that good first result with a 3D printed foil
Bigger front wing and back wing should do the trick! Bigger wings is more lift and less speed required to start foiling. Subbed, amazing project!
Make it double wing, biplane 🙃 Amazing designs and everything, as always! Cheers!
Great video! For your 3D printed foil, make it stronger by adding 2-3 layers of carbon fiber fabric/cloth or even fiberglass fabric/cloth (do not use fiberglass mat). Carbon fiber has way better mechanical properties (stiffness, rigidity, etc) . You can use an epoxy resin for that, the best resins for technical carbon parts are: epoxies and polyurethanes. Search online, you'll find a lot of details about this topic. Also, I am not an expert on hydrofoils but you probable need a bigger foil and more thrust on your motor/propeller. Good luck buddy!
What a cliffhanger, DO BIGGER WINGS!
Nice wet suit transitions!
I think it's the flexibility of the wings. When you get up to speed the wings bend up past the point were they would provide the lift required. It's similar to porpoising in F1 where the downforce applies itself to the car, then after a certain point it squeezes the car down too much and puts the car at an angle where you get lower downforce, only in your case you don't have ground effect so there's no shifting in lifting force that bounces you off the board.
Could also be that you're not going fast enough, so if you're not able to go faster you should make larger (*and* more rigid) wings.
Im hyped to see the new wings installed, nice project !
Looks like plenty of speed, general rule is start with back foot over the mast and fine tune from there. I tried standing way forward of a 2000 size foil and couldn't get it to lift in powerful waves.
You build it, we love it. I continue to dream harder. Great job.
Awesome man, you got some good speed up too! Can't wait to see the next iteration! :)
you could also watercool the ESC by drilling a small hole or channel through the mast, the water pressure from moving forward will push the water to, then one outlet and you have water cooling. have done this on rc boats. Cool Project!!
🤣 amazing work! 3D printed parts for DIY projects are genius! I also printed the whole gears and motor mounts of my e-mountainboard (8085 motors with a peak power of about 8kW) with nylon materials and a normal A8 printer - worked also perfectly!!! Maybe nylon would be a better material for your wings (little bit more flexible but stronger) maybe make them bigger for more buoyancy.
Great video! It seems you need more lift from the hydrofil. You may try changing the hydorfoil form a classical wing-tail configuration to a wing-canard configuration. A wing-canard will provide more lift while ensuring stability. Other than that, increaseing speed, increasing the main wing area on the hydofoil or tilting the main hydrofoil wing so the angle of attack of the main wing will increase may lead to generating some extra lift. Hope to see your progress in the next video!
That's a high wing loading (per area). Tiny flaws in shape, surface and angle of attack get magnified making it easy to lose laminar. More cowbell (area) needed on the wing. Some good comments on balance as well. For your "watertight" boxes, at some point you may want to suck it up and buy a plastic tote and some grommets. I know you like huge 3d prints, but....
It's good to see you back to having fun with the videos. I hope you're feeling better and enjoy continuing to inspire.
its cool to watch! Nice job Simon!!
Bigger wings will definitely help a lot and get more running time
This is good work. in my experience (I ride a windfoil) there are a few things that will happen to you :) As soon as you start to rise above the water, the foil mast will break, because, as I saw in the video, it is printed on a printer and the layers are located across the mast. Loads on a mast - lateral. Therefore, it is better to replace it with an aluminum profile (a mast for a kite) or make it from carbon fiber. You also have insufficient rigidity of the aircraft. It is also better not to be made of plastic. Alternatively, plastic can be laminated with carbon fiber or fiberglass. Well, the front fender needs more. about 1000 mm2. You don't have enough lifting power to rise above the water. But you are great. Good luck!
Add a little positive angle to your main foil like a thin washer under a grunt bolt or something like that?
Awesone to watch this video Simon! Nice editing as always :)
Your editing is fantastic. So much fun to watch and learn.
Sick! really looking forward to seeing that thing lift in the next video!
Love it ❤. Best part was the fuse sticking in board after mast broke off 😂
in your cuurent standing position u had to much leverage on the foil. to start foiling you need or the stand farther back or to take the foil forward, or go faster to get more lift. the farther forward u stand in relation to the foil u will have more leverage on it(less lift) so or stand farther back or go faster.
im a doing windsurf with hydrofoil board (windfoil) so i know a lot about it from experience, if u want id love to help u with this project by sharing ideas. id actually love to see u foil with a home made setup !
or get a bigger wing it will also create more lift
Nice work man. It will fly next time and your Cool Score will go off the chart :)
What an epic adventure! Honestly, I call this one a win
I do wingfoiling.
I Gues you need about 2000cm2 of surface area on the Frontwing and 350 in the backwing.
Great job man💪
