Your proficiency in having ideas and being able to put in the effort to make them and document everything for KZread is admirable

They are extremely difficult to ride. Especially if you don't already know how to surf/skate/wakeboard/etc.. One thing you seem to have mastered is safetly falling off. You often see surfers 'wipe out' and it looks totally random, but there is often some serious last second movements to aviod injury. Keep it up. Feels amazing once you get good.

I am proficient at Wing foiling, and i feel sometimes already knowing how to surf or wakeboard can be a hindrance in initial progression (those sports relay a lot on back foot pressure). On the are there hand skiing and powder which Riley is an expert, can be a real help. I came from snowboarding to foiling and being able to be efficient on the pitch control on deeper conditions translate almost 1:1 to foiling. Keep the good work @rctestflight this would be my favorite upload yet. Foiling rules

Do any of you know of any channels this good? Seriously. This is the only must watch channel for me.

to pump foil you need to see-saw your feet: every motion is front-foot-first. Imagine each foot is in a different car of a rollercoaster, they're following the same path through the arc, but at different times. or it's like skate boarding over a bump.

This channel is the nerdiest and most fun, of nearly all of KZread.

By far my favourite uploader! Well done mate! I always love seeing how you troubleshoot and then overcome said problem with real outside the box thinking. Great job 👏👏👏👍👍

That was very cool. The shots of the foil underwater were really neat. I like how you kept pushing and trying different things to get to this result. Looking forward to your summer board riding. 👍🏻

So happy to see bigger channels getting into this! Efoiling/hydrofoil pumping is so fun.

Gotta be one of the coolest things I've seen in a while. I can't wait to see the home-grown e foil board - I've been wanting to make my own

Try to attach a rudder and some ailerons to the foil and use waterproof servos and a flight controller to help stable the foil.

More drag would be created by underwater control surfaces. propulsion maybe, but for some reason I think axis control above water would be more efficient.

Another triumph! So amazing, I'm so happy you are able to share these videos.❤

Amazing video. Really stoked to see what you do next with it.

Great project, great video! Your persistence is inspiring 😀

Having tried a e-foilboard for the first time this year, and as a lover of all things R/C this is a 10/10 video! Bravo!

It looks like it behaves more like a bicycle. If you want to turn, yaw as you found out will cause an adverse roll the other way. However, to keep the board stable in the turn the stem needs to be leaned over such that the force remains directly down through the stem. So... to turn left, yaw right, allow the board to "fall" in the direction of turn (left) and then steer (left) into it to stop the roll. If you watch the boarders when doing a tight turn they are leaned over and to get out of the roll they kick the board to yaw it INTO the roll. Just like a "push steer" on a bike.

@ChaFairchild

You're right, except it lacks any of the automatic correction you get from the front fork of a bike. That's what makes it so difficult to master, it's not helping you by self stabilizing.

@@chrisblake4198 Also lacks the gyroscopic effects on stability and control. It does gain the water surface/plain tension though. I wonder if there was a way to implement the "trailing" effect of the front fork "rake angle". Would it be as simple as a smaller hydrofoil out in front like a rudder? Mounted in such a way that it will naturally migrate towards "understeer" such as the rake on a motorcycle or "easy rider" bicycle. Something I only learnt recently, but professional race bikes have almost zero rake. I was a mountain bike guy and have ridden straight forked bikes, but never directly down forks. Some pro racing bikes have nearly vertical forks and only a small curve out at the bottom. They are known to be incredibly responsive, incredibly low drag but also incredible unstable. Not wise to ride them "no handed!"

one person. bags of talent. great attitude. rc skillz.

For inspiration you can look to foiling boats and catamarans. In terms of independence between speed and pitch/height you should probably be vectoring the thrust depending on how high the board is using a rotating engine mount. This would increase efficiency. In terms of making it work for a human though, adding engines onto the foil instead of props in the air would be the superior method. Ideally the batteries should be a part of the board i think. Though cooling would probably become a problem as the board in flight doesn't contact the water. The ESCs would probably be cooled the easiest if they were on the foil somehow. With you on top of it you dont need to think about controls at all. You changing your center of mass would be controlling the board. Also tweaking the distance between the foils, their location relative to the center of the board and their size has a large impact on how the board behaves. This is something you didn't include in the video, and that probably could have made your pitch problems easier to solve. Also depending on how big, heavy and fast your human carrying board ends up being, you might want to look at foil designs for kitefoiling or windfoiling as the speeds there are higher and in windsurfing the weight is way higher as well. Oh and get yourself a impact vest. It makes a world of difference when falling at high speeds. Though they aren't as good floatation devices in my experience.

As an RC enthusiast and someone who rode an e-foil for the firs time last year, I am incredibly impressed by this video. Extremely fascinating. Keep it up!

Great video and project. It was impressive to see you riding one and controlling the other, talk about multitasking. So many of your projects inspire me but I don't have your natural abilities, so I watch.

My favorite of all your videos. 🎉 The high quality camera work is always stunning.

You should consider heading up to Lake Ballinger. There is a local group of pump foilers that frequently ride at the boat ramp there. They have skills, knowledge and the best pump foil gear available. It's a great crew that I got to foil with while on vacation one day last summer.

There are so good - always enjoy your content dude! Please keep creating more!

You guys are just geniuses🏆 I love nearly all your content and it is very cool interesting and exciting to follow all your amazing projects! Thanks 🙏🏻

Cool lesson in center of gravity in relation to your thrust. Looking forward to your future projects!

You're a genius happy to watch your endeavors. I find your videos are the only ones I can watch all the way through and not bounce. So much crap out there. Rc-er here just been out because of health and monetary issues associated with that. Keep it up!

Very satisfying video! You've got a great work ethic on top of everything else.

Loved this! The FPV hobby has its own mad scientist 🧑‍🔬

Thank you! This is just what I needed today.

You are really a great engineer 👍🏼 love your content

Very cool! I like how much the foil resembles a DLG.

Control surfaces on the back of the main spar? Like an upper and a lower rudder for better control of which way it wants to twist during maneuvers? Cool stuff!

Nice work! I always enjoy your videos. 😎

Genious Daniel! Your brain is admirable! Keep posting please!

Love Ya Man!!! Awesome Video! Awesome quality production!!! Awesome Team!

Awesome project! I was watching the roll control part and said outloud, move it back to the tail. I only know that from years of riding foils that the back foot controls the roll. Haha! It would be really cool to use that rig to test foils with. Then we could get much more controlled data on foil setups. Right now it's all about the way foils "feel" and very little standards to measure complete foil performance in the real world. How cool would it be to make a rc rig that would pump a foil! Imagine the data we could get from that! As always, thanks for the great content!

Real good fun. Grit determination positive outcome. Thanks rc.

Excellent video as always!

i love seeing your projects. so cool.

This is similar to my senior design project in school. Look up "UF Unmanned Foil" on KZread, we added control surfaces to the tail wing and modeled it as a delta-wing in the controller. It was great to see your take on an unmanned hydrofoil! Always hoped I'd see someone try the active weight shifting method.

combine brilliance and enthusiasm and you get this channel!

I watched your videos and recently moved to Washington State Seattle, immediately recognized nature and realized that now I can one day see your inventions on the water or in the sky

Long time Kite / wing / surf foiler here, from my experience I think you should try using more counter steering with the props in the front. It should have been possible to get it working with just the weight shifter over the center of gravity and 3 props at the front for differential steering and speed+ height control. The sideways props to help the weight shifter are a genius hotfix but shouldn't be necessary. When you initiate a turn, you can do it by the roll axis, i.e the weight shifter, and by rudder; the differntial motors. But like a bicycle, if you want to initiate a left turn, you (mostly subconsciously) turn the handlebars slightly to the right for a short moment, which makes the bike ride to the right under your body, which makes it easier to "fall" into the left leaning for the left turn. There are nice videos about counter steering with bicycles, showing that you need the ability to steer right to initiate a left turn. Like "The counter intuitive physics of turning a bike" by minute physics. Same goes here with the foil board, and its the same for initiating a turn or getting out of a turn. If the board is leaning to the left alot and you want to get it back to level, you should steer right with the weight shifter, but left with the rudder; the differential steering with the props. In the video it looks like you tried getting the board level again by both steering the weight and the differential thrust to the same direction, or at least kept the heading straight while steering max with the weight shifter, which didn't help and didn't worked. Please try it out, as it is something you can try without rebuilding, just tempering with the steering programming, or try it manually. Would be interesting to see if this is enough to stop using the sideway props to help the weight shifter. They just look like unnecessary overkill to me, lol. Ah, yeah, in your demonstration at 5:21 you clearly showed mapping left weight shift together with the right prop turning on; which is basically rudder left. So you basically try to steer it like a car and force the balance, when you should use counter steering to balance and steer it like a bike.

You are so far above what I’ll ever do, but I love watching it! KZread is good for that! I still love your homemade planes from years ago.

I applaud your ingenuity and out of the box approach to problem solving. I’m wondering whether due to the density of water, if rather than controlling the movement with propellers above the board, if real time micro adjustments to the underwater foil’s angle of attack, based on height above the water would be a more elegant and efficient way to control the movement. I’d be delighted to collaborate.

Love this channel... You never know what's next.

Well done you!! ❤ I wager you could rig control surfaces on the foils themselves. E-foiling - wing foiling. wind foiling - kite foiling, will all become accessible to millions. You are a hero.

Brilliant!! As a foiler I appreciate the effort put into learning to fly. Come up with a jet propulsion system that is affordable like foil drive and look out !

This is a great project. What’s funny is that by the time it was stable, you basically made a drone that probably could have flown without the hydrofoil! I’ve been learning to wake foil in boat wake, and these foils are definitely not stable. The yaw/roll coupling is very weird. Makes me wonder why no one has made a foil with dihedral in the wing?

Like some other commenters have pointed out, a foil board has roll control via countersteer. However, my understanding of the dynamics of foil boarding suggest a unicycle a closer analog than a bicycle. Probably even closer would be a foiling windsurfer because of your aerodynamic roll control. You successfully created a vehicle with a very unique set of lift/thrust/stability interactions. Your projects are so interesting and admirable!!

Ideas into action- new transportation from this well done

Always a pleasure 💪🏻

This is the best video you've done in a long time absolutely outstanding👍👍👍👍👍

Dude you are so much fun. The perfect bridge between the divergent and the almost-divergent.

Every one of your videos is crazy and awesome!!

Excellent work!!!

You did a lot of good work to get to a working prototype. One thing to consider, foils are designed with anhedral to make the setup maneuverable. A foil with dihedral would increase stability.

One of your best contraptions. 👍👍

That thing is so cool. Hydrofoils are just great.

I think one of the reasons you were getting so much roll/yaw coupling because the two props you were using for yaw and forward thrust were tilted up. Whenever a motor applied yaw force it was providing part of it's force upwards, creating roll. Separating the yaw and forward thrust motors would allow you to angle your thrust motors up and your yaw motors forwards, removing their influence on roll.

Social media definitely makes that stuff look easy. I mean I can ride almost any board with ease but that’s from like a decade and a half of riding them lol. Pure muscle memory at this point. 100% bust my ass all the time, but now with the added adult fear of dying! Social media is just the highlights. Love the brave bottle quad! Used to fly over water and have to hunt for info on waterproofing and safety with my FPV quads. As shown you can get some neat footage if you’re prepared to dive and man had no fear immediate send!

I absolutely cannot do electrical engineering, or wiring for that matter, but I thoroughly enjoy seeing the outcome of someone that uses their knowledge. I ended up being a carpenter because it was what I enjoyed problem solving, and I can see that here. Bravo! P.S. I fell in love with carpentry in Snoqualmie. I learned my love of the craft on the very lakefronts you test on. It was 2007-ish, so long ago.....

Totally tubular. Love it 😀

Thats super cool. As someone who does a lot of foiling, it's cool to see how someone would go about controlling one electronically.

well done. good engineering 👍

man you keep coming up with great idea's.

Great project and video! I could have sworn you were going to use the weight shift for pitch control. Can’t wait to see what’s next!

Ah, can't wait for more RC adventures as the weather warms up.

I love your work and this is my favorite episode.

Really clever solutions! I'm amazed the level of effort you put into your projects. In this case though, I think perhaps you should to change your design paradigm. Maybe try a gyroscope.

What a great project. 👍 Try a high aspect ratio wing for pump foiling 😃

This is freaking awesome

I love this channel so much, so interesting

It's crazy how smooth it flys, would be intresting to see if a scaled up version of this could survive larger waves. if so, I could see it being used for filming

this channel is just fantastic love all you curious bastards cheers

Very cool, you could also build the equivalent to controllable ailerons and rudder to the foil itself leaving the board clean and ridable. You would need a drone type controller to aim for level etc.

As always Daniel, you never cease to amaze. I love your content, it’s always really cool. There’s only one problem that I find. I have no idea what language you are speaking (that’s code for I don’t understand the technical aspects of your builds).

The idea of making a drone with a foil board is a good one. You will achieve much better results with the propulsion behind, and underwater, like jet skis have.

Love watching these vids

Love the idea without even watching the full video

Great problem solving

Well done!

that was pretty amazing actually

That is so neat!! Well done! Did you get funny looks from people passing by? I have an e foil board and i use it in places here in Australia where they simply have not seen one before!! Having a foil board that flys without someone on it must be a first too!!!

Very entertaining. Thank you.

I love your crazy projects. 😂👌🏼

When you were riding one board and controlling the other board it reminded me of the mini-game in Fusion Frenzy where the players control their character with one thumbstick and a little bomb with the other thumb stick. You try to run your bomb into other characters while avoiding their bombs. It's freaking hard.

Lake Union and Lake Washington? I enjoyed your approach to the problems. Great work! It worked!

Board is good for pumpfoil, in the shots you got the balance and start right but you didn't generate enough front foot pressure. Just in case you wanna try this again. Thanks for sharing this very interesting project.

rcfleshlight I'm always so hyped when you upload! great video
