R/C Hydrofoil with Sonar Pt.1 - Build 

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

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

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

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 !

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.

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

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

“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.

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

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

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

@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!!!

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

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.

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

Hey Daniel, quick question - would a foil with a tube connection (or multiple) between a point on the mast and the laminar surface of the foil wing stabilise ? And would a two mast-three-foil setup not even stabilise in vertical and horizontal direction ?

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

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.

I can't wait to see your Mars copter.

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.

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

Galaxy Funfetti, ah a man of culture!

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

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! 👍👍👍

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!

These videos are something else man, good fuckin shit Daniel

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

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

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

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

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

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

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

You HAVE to make a boat with a sail!!

Yes, that 2011 footage was incredible

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)

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

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?

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

Damn, Daniel is moving up in this world.

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

very cool, an extra touch with the old videos.

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

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.

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

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

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. 😄👍

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

420% conversation rate. Blaze it!

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

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

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

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.

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

The google satellite view is priceless!

I'm so happy to be an early riser. And I just watched SpaceX launch. Nice.

Question: Why do you use airscrews for propulsion? Wouldn't it be better if you put the propeller underwater? (with chain drive or smth)

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.

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

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!

The results seemed pretty good looking to me

lol! Your old ground effect vehicle has joined the ranks of "spotted by satellite"

wow those unpeeling lights were really cool!

nice

Smooth-on has a product that you can brush onto 3D prints to make them smoother. You might still need to sand the edges, but it could help you save some time and effort.

Triboluminescence X-rays apparently our only generated when under vacuum. In atmosphere you are all good.

Probably the only guy that creates X-Rays while making an R/C boat xD

Damn, that Triboluminescence is so bright!

You should build a long range hydrofoil boat because I think it might be more efficient

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

pro tip for 3d printed finishing -- instead of just sanding, try using a blow torch to lightly melt the exterior (works best on solid bits), and then sand any small bumps or edges! gets rid of any discolored plastics, gives it a great shine, and will make the piece slightly stronger as the filament marks are now welded together a bit better! that, or try using a plastidip or thick/durable paint to fill in gaps easily

Alexander Graham Bell did a lot of research into hydrofoils in the early 1900s, cumulating with the HD-4 or Hydrodome number 4 which Bell designed and built at Beinn Bhreagh Labs in Nova Scotia, Canada. In 1919 it set a world marine speed record of 70.86 miles per hour (114.04 km/h).

Lol @8:26 those ducks passing by like "check out this fuckin' guy."

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

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

I love when you design boats!

It's interesting how you have to make your fins smooth yet fish and sharks have pointy teeth like scales that allow them to go faster using their turbulence. Wonder if a sharkskin inspired material would work even better.

I think you should definitely do more explaining about the "luminescent x-ray" I've never seen anything like that, that was crazy.

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.

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

Just an idea, instead of gluing 3D prints together i melt them together with a soldering iron, it's a much stronger bond, way less messy, but sometimes can require some extra design steps to hide the seams if necessary.

Take a fishing rod with you next time, saved me more than once when I had a nitro boat

I find it stunning that these types of DIY-build channels went from using nothing but styrofoam, wooden sticks and underpowered motors to using 3D-printers, fibre glass and carbon fibre in just a few years

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

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

waiting eagerly for part 2

Note to self, things catch on fire. 😋👍

I can almost smell the epoxy lol. this brings back memories of building my plywood sailing dinghy

this project is sick, cant wait for part 2

I just love how properly you do everything :-)

How bout this idea. You have the skills to make this happen.

Project idea: Build a RC boat of some kind to retrieve your other water based projects if they happen to catch fire or run out of battery.

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.

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.

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!

My thought is that you need to put the propulsion underwater so you can run the motor and craft at a slower more controlled speed. Also, to maintain a constant height, I think you need some kind of height sensor under the craft so that the wings need to know what angle to adjust to vs running just on top of the water. Otherwise it's a neat video and concept. Love your manufacturing process with all the parts.

Awesome project and awesome video!

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

Simply for the google fun fact it's a like here. Still amazing men, keep going !
