[@bAc0nBoY755]

Definitely would like to see you keep improving this board

[@theroburrito]

From the drone world (not sure how applicable to water), flat edged bullnose propellers are used with ducts to minimize the gap between the duct and propeller to improve efficiency. But when used without a duct, they have much worse efficiency than a standard propeller - but more thrust because of the larger area. You should collab with rctestflight! He's been testing 3d printed propeller designs for his autonomous boat.

[@russellzauner]

If he's gonna use a naked prop then 100% should be chasing down toroid designs to remove cavitation and turbulence, which increases efficiency. It is very much worth it to try at least one toroid design before switching over to jets 😀

[@sc0or]

Each motor has its own ideal prop. Because of a watt/torque/volt/rpm curve

[@jamesdouglaswhite]

Great suggestion to collaborate with rctestflight!

[@T3chpat]

As several people have pointed out, @RCTestFlight is awsome on custom props and seems like a real chill guy, would love to see you doing a colab! Stay cool Edwin!

[@PlaneAwesome]

I love your palpable excitement at seeing your first self-designed part come to life on the printer! A 3D printer is honestly one of the best investments you can make for prototyping and experimenting like this. Fantastic video! You definitely inspire me to get a cheap e-foil and start tinkering myself.

[@Cherokeeseeker]

A thing you might try to help with drag or stability on your hydrofoil, adding 'vortex generators' might help. These are small ridges or bumps that create tiny swirls in the water, keeping the flow attached to the foil longer and reducing drag. This can lead to a smoother and more stable ride. It’s a technique used in aviation and racing that could potentially enhance your hydrofoil's performance. Might help.

[@bashr52]

Just a few printing tips. You shouldn't need any support for a cone, each layer should print on the last which makes its own support. I would also suggest you use ABS for strength and UV stability. PLA will break down in sunlight and is more brittle than ABS.

[@friedclutch97]

I was thinking the same thing about the support. PETG would also be good here.

[@GingerNinja1]

It's awesome watching ppl realize how much potential they have & the great thing is... this is only the beginning! I say keep going until you can't take it any further with this board. 🏄‍♂️

[@TB12710]

Wow, you switched out one part that you made with your 3D print and now you’re getting almost 15 miles at 23+ mph. Now it’s time to improve your wing. Do that and you might hit 18-20 miles efficiency at 27 to 30+ mph. You made your board so much better, congrats to you.

[@Crunch_dGH]

Now sell your IP (& advice) to the maker!

[@thesustainabilitysoonerchannel]

Great start! Take it from someone whose done hydrodynamics and prop work for numerous marine manufacturers and world champion race boats. Perfect your foil and all the running gear in front of the prop first. Save the prop optimization until last. Also, only change one element at a time. Otherwise, you'll be chasing your tail. Just found your channel and subscribed...looking fwd to seeing your progress. Keep going on this one until your optimization is complete. You'll master both your project and your 3D printer. Plus, what you learn aid you on whatever project you choose next...

[@criticalevent]

I was surprised how well that prop worked considering it's squared off to work with the shroud. If you haven't seen his channel already, @rctestflight has done a lot of research on 3D printed props.

[@bretts7085]

Great Vid Edwin, yea continue to take this further ide be interested to see how much better you can make it. 👍

[@alanpaone]

I guess it depends, but you've got the 3d printer already. Personally, I love to mix one hobby with another. As long as you're enjoying the mods, and the time you're spending tinkering with your board isn't taking away from the time you'd spending riding it, it can be really rewarding. I say ride it until you can't fix it anymore.

Reading other comments, it looks like the majority would like to see you continue to mod it as best you can and share that journey. I mean, like GHP it's the journey of the thing that is interesting. Personally, I'm the one guy that wants you to hop on the top of the line, completely sorted e foil and enjoy miles of smiles with it. I want to watch you push the envelope with a better design that already exists but I get it, it's probably boring content compared to the improvement process with what you have. Either way it's good stuff man. Fun video and I applaud all your effort to make el cheapo fly. Looking forward to the next update of your e foil journey. Cheers.

You could try hanging a weight under the middle of your printer/plant table, if you don't want to get a new table. ;) Thanks for the update! If it's worth it for YOU, it'd be cool to see what you can come up with to make the ultimate upgraded cheapest efoil. Maybe get (or rent) an off-the-shelf nice-one first to get another baseline for upgrade comparisons.

Keep going with what you have. The improvements/enhancements that you make that work for you will show you what to look for if you decide on a new board as well as improving many skills. New subscriber here.

[@fluiditynz]

I design my own foils and I wingsurf. You should streamline your motor more, use socket head cap screws for smaller head diameter. Try to get a smooth flow off the motor to the hub and consider a cone behind the prop. The motor is pretty large diameter providing a lot of it's own drag. Surfaces under water are important, try wet sanding to 1000 grit, a water jet should slick on the surface with no beading. For silicon sealant, ensure you use neutral cure, regular one emits acetic acid on cure and can wreck electronics. The sealed from manufacture parts are probably polyester resin, it shrinks over time as it's solvent evaporates.

[@AlexNichiporchik]

[@ryandoyle4344]

Magnets may not be the issue, it's could be the cord length. That cord type tends to stretch over time, if so it may drag on occasions, and might just need to shorten it a bit.

[@Hobbies4Hire]

Great job on the video Edwin! Thanks for making it. Now throw a toroidal propeller on there and see what difference that makes to your efficiency.

Good stuff Bro !!! You should finish this one, there is more to improve for sure, showing how you fix the stability issues is worth the time. The 3D printer is really interesting as well.

[@marielarebelo9194]

That underwater shot looks awesome

[@markjennings2315]

Shrouds or ducts around ‘propellers’ are there not for propulsion but for a secondary purpose ( such as safety or directional flow) so are Always going to cause a loss of efficiency compared to an un-shrouded prop. As for stability, drag is proportional to stability

[@lsdave]

Cool channel, new subscriber here... Pro tip on working with silicone: Use an ice cube to smooth over. Silicone obviously doesn't stick to melting ice, and water doesn't affect/mess-with silicone (wet or dry).

[@tappan48]

The original set up requires the flat prop blades because they're designed to work with the shroud, but that shroud needs improvement, perhaps carbon fiber and a more defined airfoil shape? Print a prop for it...

[@SilvaDreams]

Yeah it works like a ducted fan (like a fan for a computer case for the computer guys) but that shroud was big, bulky and I'm guessing made of some cheap cast metal so it was a virtual lead weight and not very optimized (likely a copy of something cheap from 40 years ago)

[@deathdrop3235]

I would like to see a prop design competition for your sub's with a leader board in the back ground. Who can make the best designed prop that will provide both speed and stability for the board.

[@penguiin12]

edwin, the "shroud" from the prop is actually a nozzle and like others have mentioned you dont wanna delete the nozzle without changing the propeller geometry with it

Thanks for the project, You did all the things i have wanted to do but i didnt have the time and money to do. Great i can rest easy that its already been done. Really fun video, well done. I can see E-foiling becoming popular like kayaking. PS. What do you think about putting a sliding chair on it. lower center of gravity and less squirrely maybe. Control would be joystick/handles on your sides and sliding chair back and forth and leaning. I am into distance not short jaunts. Thanks again.

Yeah, use a better prop and a more progressive taper on the cone. The cone can be pretty thin and it can be taped on with vinyl tape carefully. I put vinyl tape over the screws on my F4 and it is so silent. Of course I'm using the sail for power. I reassemble my foil every time because I'm in saltwater

The prop guard on these are designed to lower the bow so thats why you have to push down to ride level now, also they create thrust so i am thinking you could print a new lighter guard with a smaller tolerance between the prop to get more thrust and better performance.

[@kschroppe]

Square blades create two points of cavitation as a submarine sonar tech I can tell you as when you go to a similar prop to the gold one you will gain power as you reduce cavitation. Also there is a new prop design out in the world that is way more efficient look into the Sharrow prop design to make a better setup good luck I hope you read this.

[@GaragenHaus-o5u]

I think the holes below your new white chaulk is just screwholes for the bulky stock cone end and if the motor is sealed than that seal should be more inside. I would like to see you combine your new end cone and the stock one into one optimized part.

[@hansklein8024]

Thank you for this follow-up video! If you take off the prop guard, you should really wear al least shoes. I always wear light diver's shoes and also a Long John suit. And in a few occasions it was good I had them. For stability I'd say you could start with bringing your back foot more forward. Your weight should be equally distributed to both feet when flying level. From the footage it looks as if your rear foot was way too far back. So my recommendation is to first play with your position on the board. There are mount kits that will vary either the angle of the wing to the fuselage or the angle of the mast to the board. But I would try that only if your board really doesn't fly at all or has a very hard time to do so. Concerning the prop I'd really be interesed in how you'll do that. In an ideal world all the components of all the boards would just fit. Just like it is in wind surfing. In the old days there was a huge number of fin and mast mounts and now there are at least some standards. Maybe this will happen when more people get into this sport, so thank you again for promoting it.

[@DrSpoon69]

As others have said, ask rctestflight if he can give pointers regarding the prop. I'm jealous that you started your modeling/3D printing with a X1 though 😂. Look forward to seeing how far you can max out the board!

[@fallingwater]

I *think* you could avoid all the supports if you simply printed that model upside down. It takes a while designing stuff before you get into the mindset of designing supports out of your prints as aggressively as possible, but it *really* helps once you decide to graduate from PLA to PETG and it always saves a bunch of material.

[@petercornish9903]

I would very much like to see how you re-angle the foil to raise the board nose, and see how much better the performance is with a prop with proper tips for use without a duct.

[@longboarderanonymous5718]

Yes keep modding the Ali E foil.. Now I want to get one.

[@TheSharkGirls]

To change the pitch of your aerofoil you can perhaps try what the guys at Veem are doing with propellers. They make props with plastic inserts which change the pitch and also for these revolutionary Sharrow props. Perhaps you mightn't need to make a new wing, just add a slot and a piece of plastic.

[@berniedmj1]

Instead of using a GoPro, perhaps trying the insta360 x4 action camera? Place it anywhere, push record & go without making an effort to always try to be in front of the regular camera to capture what you’re doing. Because we all know when something crazy happens, it happens behind the camera. With the insta360 camera, you won’t miss a thing (unless you didn’t push record or forgot to charge the battery).
