R/C Hydrofoil with Sonar Pt.1 - Build 

The triboluminescent x-rays were very cool 👍 I’d love to see someone do a video on this phenomenon

To be fair, for how many projects you do and have made, surprisingly few have caught on fire!

Maybe you could design a simple RC rescue vessel to push your stranded experimental boats back to shore ? Something small enough to bring along with you without it being a hurdle. And simple and proven enough so it doesn't require a second rescue vessel to rescue your rescue vessel in case of an accident !

Lovely, Saturday lunch time in the UK, not eaten yet, so will enjoy to watch this with my lunch.

“You could even see it from the Google earth satellite view for awhile.” I don’t know why, but that feels like a hell of an accomplishment. I’d probably have had that image printed out and framed for shits and giggles...

Filler primer makes short work of fdm ridges. Much less time than sanding the ridges smooth.

Can't wait to see you build an autonomous submarine.

People like you are why I can't understand why some huge companies employ thousands of people in research and development. They seem to be less productive. Amazing as always. Epic skills.

This guy is working at a high level in, fiber glass, carbon fiber, wood, foam, 3D printing. Then, add RC on top on that.

As a retired submarine sonar tech of 17 years I love this, I have always been fascinated by hydrofoil craft

This is when a fire engine boat would come in handy, you could control it to put the fire out, then use a mini harpoon (that you attached beforehand) to tug it back in.

Amazing work my dude, anybody can tell that you deeply enjoy these projects and we do as well because of it! Kudos

"I used my 3D printer bed as a curing oven" Yup, we've all been there 😂

You're hands down the most entertaining RC channel on the platform, imo. Good at explaining without lingering

@7:53 Always love your videos and all the awesome projects you do, Had an ESC do the same thing while on my plane was not a fun time haha. Keep up the great videos!!!

I been operating snowcat for 7 years im just now hearing about this project.. im hella pumped!! Definitely subscribed!

Congratulations on your success with the snocat! I love seeing people succeed in endeavors like that. Also, what a neat idea for a boat! Can't wait to see what you do with it.

God damn I love your videos. That triboluminescence is absolutely insane. It's so much brighter than I've ever seen before.

Fire! Was literally dreaming about a design this past weekend after seeing that electric hydrofoil

Yessss hydrofoil episode! Finally! The more I see you post the more I like your ideas. Keep it up, man!

You've really stepped up your fabrication, great work 👍

You make the most quality TV. So enjoyable!

Still not sure how this channel isn't at 1 mil subscribers with all this awesome content.

Above my level of experience and expertise! Must say this is super cool and the difference between a racer like myself and a real engineer. I have no desire to do this but I still enjoy the video

Excellent. Love the colour scheme . Waiting for the sails tho. That will be FUN

Your videomaking is top level 🙏👍. Looking forward to the next 😃

It's great that you keep doing interesting things. I look forward to continuing.

I just love how properly you do everything :-)

At the Boeing museum in Seattle, there is a boat called the Little Squirt. I think you would find its hydrofoil and propulsion inspiring for this project. Loved the video and I can't wait to see more! 👍👍👍

Another great video, looking forward to the next one. Thanks.

very cool, an extra touch with the old videos.

That was awesome and funny to watch run on the water, lol. Look forward to part 2.

Most RU-vid I just put on in the background while I'm doing stuff, but I watch your videos like there is going to be a test.

this project is sick, cant wait for part 2

Amazing to watch you work

Loving the build! Next time you go out to the water to test, you should bring a fishing rod. Would be handy for retrieving stuck boats lol

Daniel and a new project on a dreary Saturday morning... Perfect. Where's my lighter? ô¿ô

Hydrofoils!! The autonomous boat family is almost complete now :))

Awesome project and awesome video!

wow those unpeeling lights were really cool!

I can't wait to see your Mars copter.

I'm excited for part 2!

pretty exciting project, cant wait to see what next

I love when you design boats!

The results seemed pretty good looking to me

The heck??! No ship fire sea shanty? Nice to see footage from the good old days though!

I recognize that beach! I launched my kayak from there a few months ago!

I really like hydrofoil ships. In childhood i saw them running back and forth on Volga. "Rocket", "Meteor", "Typhoon", "Arrow" and more and more... We had a massive River ships park a long time ago. Sadly, now all we have is a metal scrap. And two-three ships in St. Petersburg.

Would have liked one of those special songs at the moment of the fire :) Great video as always.

That’s insane that the satelite snapped a photo right when you were testing

These videos are something else man, good fuckin shit Daniel

So cool.man love your vids and instructional voice overs!🧾

Fantastic work again! Are your foils the effective/efficient size for the weight of your craft and the drag of the wetted surface? What are you using to calculate the measurements? Do you plan to address the wracking and instability of the rudder foil?

Pls post more! I love watching your videos! its super entertaining!!

Nice! I tried making a foiling sailing boat (Americas Cup AC75) I used an arduino an ultrasonic sensor and an IMU. I couldn't get to tuning PIDs because I struggled making the cant arms light and strong without any slop. Maybe I'll get back to the project!

A lot of smaller hydrofoil sailboats use a simple physical mechanism to control "flying" height. Like a float on a lever connected to the hydrofoil control. When the boat gets high enough out of the water, the lever drops and pulls the hydrofoil down, stopping the boat from rising anymore. It's a nice feedback mechanism that makes for easy control. You could also do something similar with a sensor connected to the lever, and/or a lever that physically overrides the height control at the upper limit?

Great job as usual. Of course looking forward to more music. :)

great work like always!!

Using your 3D printer as a curing oven is genius! Your upload rate is very impressive. Where do you find the time in the day make so much good content? (Asking for a friend)

When I was a kid, my dad and his RC friends were into boats for a bit. My dad had an RC racing boat that would die in the middle of the water when it ran out of fuel. So he had a cheap Walmart RC wave boat with a length of rope tied to the back and a fishing bobbler on the end of the rope and he’d use the Walmart boat to loop around the racing boat, snag the rope on the rudder, and tow the racing boat back to shore. Some of the other guys had a fishing pole with tennis ball tied to the end of the line so they could cast out over the boat and hopefully snag the tennis ball on the boat as they reeled in and they could pull their boat to shore. Maybe bring some nylon rope with a tennis ball with you for these boat experiments so you don’t have to wait for it to float back to shore or get wet swimming out to it, assuming it’s in range... Or use a drone to drop the line over the boat then pull it to shore

This is such an awesome channel

For 3D-printing the foil, it will be *much smoother* out of the box if you print it vertically (standing up), with a brim enabled in your slicer to keep it from falling during printing. 😄👍

I love your videos it always makes me happy when I see them

great project and more to come!!

Dude, use at least PET-G for your functional parts! PLA will soften in you car on a warm day. Since you've got an enclosed 3D printer, you can use ABS, or even Polycarbonate, though those will be more challenging to print correctly. Awesome work as always!

Wow that's some of the brightest triboluminescence I've seen

Great video can’t wait to see the next one 👍

Aha, brilliant. Everything I consider you actually do. Don't let some big corporation buy your incredible skill for buttons!

When that thing lit on fire, I was hoping a new sea shanty was going to kick in.

Nice work!

Galaxy Funfetti, ah a man of culture!

Damn, that Triboluminescence is so bright!

Damn, Daniel is moving up in this world.

Keep up the great work bro

Some very cool building techniques with CNC and 3d_print equipment. Daniel is really upping his project experimenting abilities. Do all 3 wings need to pivot? Like a flying wings elevons, think only the front two would be enough. Having the 3rd rear pivot is likely making pitch control much more complex and sensitive. The tip over roll effect is likely being caused by cross control condition of aileron and ruder action, where the boat ends up with sideslip motion relative to water vs forward.

just a little tip. use heavier hulls for more velocity speed, add a skip to the bottom of each hull, and a fine grill infront of the propeller to catch anny debris and to break up waterdroplets... alldo if you want controlling to be easier use rotary dials so you can lock the ailerons and elevator at certain angles so you dont have to wobble around 50 individual controlls! allso you could call up a friend to help stear it... its a lot easier with dual piloting

i would use a single hull instead of 3. makes for easier weight placement. i would also make the foils shorter so that the top height becomes lower

Amazing! 10 billions dollars revenue is quite impressive for the snowcat!

This is great, very well done (:

If you wind up building a second one, I would redesign the tilting mechanism for the foils so that the foils pivot at the top of the vertical part. You could probably drastically reduce the size of the vertical part of the foils, and make the transition area much smoother, which would reduce your drag by a good bit. The downside is that control forces will probably be way higher, as the servo will now have to work against a big lever.

You've got some cool tools and ideas. Wish I was your neighbor😜

very cool, this could be a super efficient long range boat.

Great job sir!

Daniel, looking forward to see what the FC can do. I considered using one myself for adjusting ride heigth of a hydrofoil boat (mine is ending up more like a SWATH, though). I got sidetracked by some 1:1 plane activity, but was experimenting with the BMP280 pressure sensor for ride height input (Ultrasonic sensors don't work well at small scale). Use one on a $5 break out board and feed the I2C to the FC. You may need to place it inside a special cavity with a flexible membrane. I hope you can figure out a clever and practical solution to this :)

There is a sailing boat called the mach 2 or moth (depending on who you ask) this uses a ‘wand’ to control the lift. The way this works is it skips across the water in front of the boat and the smaller the angle of the wand to the boat the more lift the foil creates.

O MY GOSH. I'm also planing on 3d printing à boat, to slaping on some electronics... Mate sooo awesome :DDDD

Great work! I am building a sailing hydrofoil boat on my channel and will convert it to L style foils as well so I am super interested in your design!

Sanding does work for 3d printing asthetic pieces. For something like this in the water; though, you really want to use an epoxy fairing compound to fill in the grooves, not break down the ridges.

Man, I love your boat projects so much! This was super cool, I'm sorry all the work you put into the fiberglass was undermined somewhat by your ESC catching on fire lol. Looking forward to future videos and projects, especially aquatic ones! P.S. an autonomous sailboat would be super dope, they make RC sailboats already but I feel like making ardupilot depend on a wind sensor and figure out tacking and stuff would be real neat. Alternatively, just deploying sails on the Banana Slug for help on the downwinds would be cool too. Love your work!

I think you could get a little passive stabilization by putting fixed foils on the verticals about half way up on the verticals. Give them only minimal angle so that leaving/entering the water doesn't create too abrupt of a change in lift/drag. That way the lift automatically gets reduced as soon as the fixed foils leave the water. Might also increase the max speed as smaller controlled foils could still lift it with the fixed ones out of the water at higher speeds.

You should make an rc snowplow! Maybe just add a plowing scoop on the front of the snow cat?

That is an awesome control problem! Next up, add sails! And make it a monohull. You'll be tackling the problems of current America's Cup "boats".

great project! But I must ask, why sand the 3d printed foil when you are going to fiberglass it anyway? Might as well sand after?

Im a professional in engineering with 69 years of experience and 420 patents in water technology.... I can tell you adding googlie eyes will make it alot more hydro dynamic

you just impress the shit outa me every single time. How do you just know to just do all this stuff

To retrieve my RC boat from the shore I used to carry a large fishing pole with a good spinner reel and one of those nerf footballs attached to the end. If you hit behind the boat on a reasonably straight line to where you are standing you could walk the necessary direction on the shore to get the line over the boat and just reel the football to the boat and bring it all in gently. You would not believe how far you can make that nerf dart go with a very hard cast. It made a good standard line cast look like an absolute joke. I thought the fire was pretty cool. At least you got it on video. You might want to look at micro-balloons to add to the epoxy to make a very light and easily sandable filler. We used it regularly building a Long EZ. You mix it about the consistency of peanut butter, so it spreads easily and doesn't sag when filling. The downside is it requires another curing cycle, obviously. And wear a mask when sanding fiberglass. When it gets in your lungs it NEVER goes away, and it is so sharp it reeks havoc when the lung expands and contracts. It's chemically inert, but so is asbestos, I think, so that doesn't help much. Very tiny strands of sanding 'dust' are quite easily kept aloft for long enough to breathe them. Enjoyed the vid. Nice work. It looks to me like you have WAY more travel than you need on those foils, BTW. Remember that wings operate very differently in air than foils in water, as you pointed out. I think a little pitch change goes a long way. I'm also a bit concerned that the bandwidth might be a bit too low, but time will tell. Great project, can't wait to see it all up and working.

While not what you intended, a vessel with enough power to rapidly alternate between tap dancing on the surface and plunging down to the normal level... it's sure a hilariously entertaining way to travel! A new theme park ride?

I think you could consider the passive foiling systems that both Aquila (36 foo) and Insetta (35 foot) use on their catamarans fully submerged. Admittedly neither lifts the hulls COMPLETELY out of the water, but they're far enough to get some serious speed and fuel efficiency boosts compared to non-foiling cats.

Yes, that 2011 footage was incredible

You HAVE to make a boat with a sail!!
