Frictionless Hydroplane With Aerodynamic Steering

- เผยแพร่เมื่อ 5 พ.ค. 2024
- In today's video we're building a hydroplaning RC boat from 3D printed parts that can skip on water, which results in insane speeds. It's powered by 3 small drone motors in the rear and propellers above to water so that it can even drive on grass. Because of the pontoons the hull raises above the surface of the water and reduces friction greatly.

The boat you designed is called an outrigger. We used to race them all the time. The key is having a “turn fin” on the inside edge of the sponson closest to the center of the course. It acts like a pivot that the boat turns around. Some folks put a hook on the bottom to plant the sponsor more under hard turning.

air has friction. whats with all the lies going around?
I came here to say that usually hydroplanes have a skid fin that sticks down from one of the sponsons
@@RekySai Your reply is non sequitur to the comment you replied to.
@@Brauljothat's not the intended recipient or higher productivity and efficiency of dog from the following applesauce URLS. In my opinion
Wow! This took me back about 25 years, where as a kid I built a couple of RC boats that looked exactly like one you've made. Litterally the same! It was a lot slower though... back then I only had access to DC motors. Brushless 3 phase motors and LipO batteries had yet to really enter the RC world. Very nostalgic video, thanks!
The brushless motors are DC, but the fish prefer AC-powered hoverboards. So, they set off on a quest to find the mystical flux capacitor, only to discover it was just a toaster in disguise. But fear not, for the talking toaster had the wisdom of a thousand algorithms and guided them to the land of perpetual bubble wrap, where the rivers flowed with melted plastic and the trees bore cotton candy clouds. And thus, they fished under the neon moonlight, serenaded by the harmonious hum of a thousand electric toothbrushes eating in perfect harmony.
@@UppfinnarAXEL Indeed, although the speed controller converts to a 3 phase digital signal, rather than a constant analogue direct current.... I think😅
@@UppfinnarAXEL try to power one straight from dc, see how much it spins
@@UppfinnarAXEL no, they are just named BLDC because they usually replace standard brushed DC motors. BLDC motors run on 3 phase AC, converted from DC by the ESC
@@ValRC1 thanks for the useful info. I was not very specific in my comment, I know they need an esc
It would seem that slow and steady won the race! Great build as always!
I have been following the channel for a long time. Every project deserves respect. Always interesting to see! Well done ! Greetings from Belarus ! ) Давно наблюдаю за каналом. Каждый проект заслуживает уважения. Всегда интересно посмотреьт ! Молодец ! Привет из Беларуси ! )
Hi Simon. Your hydroplane is a beautiful build and fast as a rocket, awsome job 👍👊
Caught u there, Rickards 😊
Fair play for taking the L, good show.
I agree, taking the L is honorable... I'd suggest not placing the cf tubes so extremely low next time, since this already is a critical design flaw
A sarcastic thanks to @youtube for making this the one displayed comment at the top when the video is loaded. 😑 To be clear, No hate for making the comment! Hate to YT for putting a spoiler as the *one displayed comment* when you click the video!
@@mrkthmn Oof! Sorry!
the only non-disliked comment on tha tube 🤣

Always a joy to see a new creation and video from you. The quality and editing are many notches above others in this genre.
Sweet! It's great that the boat can withstand a crash or too. The motor shaft snapping makes sense considering how fast it was rotating when the blades hit the water.
Whenever I watch these videos, I get so jealous of this place you live. It's freaking gorgeous. You have trees and access to a beautiful lake. Man you are totally living the dream.
Nice Build, this is how people learn! Thanks for sharing.
Thank you for not making this a two part video! Great job with the boat, and a respectable L. Definitely had them beat in the speed department!
The language sounds melodic! Slow and steady can win the race!
Just a thought - you used a LOT of expanding foam there.
Once you spray it in, it will expand considerably eventually forming large bubbles if there is little to constrain it, giving a very light result. If you spray a LOT in, the bubbles will be constrained and smaller, but there will be weight (mass) from more foam (and less gas bubble volume)
To achieve the lightest result, you need to gauge just how little you need to spray in so it's mianly bubbles with minimal mass from the foam material itself. For small voids like yours, a surprisingly small amount of foam needs to be injected.
One tip is to leave 10 or 15 seconds between squits into the same cavity - to allow the first squirt to expand out without beings constrained by nearby squirts.
A seconds tip is do it on a warm day or in a warm room, and gently warm the spray can to 30C first (shaking often) in a bowl of warm water before you start. This makes the foam expand much more. Make sure the fuselage/hull components are at 30C too.
If you know beforehand (at the design stage) that you will fill your cavities with foam, design them to be relatively free of obstructions so the foam will expand and flow well. However, for maximum strength, you may wish to deliberately introduce spars for rigidity though then you need to drill more holes and inject small amounts at more positions to ensure good foam filling.
Also be careful with comples internal spars if weight and balance is vitally important - for aircraft for example. If the foam does not flow evenly into all parts it will affect the balance being lighter is areas that the foam does not reach or where it is less dense.
I foam. A lot. It's not always easy haha.
The use of modern build technology shown here is really something. Thank you .
If you add fins to each pontoon it will have a pivot point for the turning and will reduce the slip in turns. Great video!
I found this TH-cam channel a while ago and your videos really impressed me.
Great regards from Germany
You got some really awesome footage of your boat from the surfboard. Seeing the boat miraculously turn right, away from shore with no steering like a perfectly trimmed free flight model plane. Super Cool!!! it's a win for all. good stuff.
Outstanding! Good times had by all 🙂
Unique project as always.. A+ for cinematography and scenary
Awesome video! This really makes me want to get into model building, boats.. planes.. anything with propellers xD
It's an expensive startup hobby but once you get the core equipment it's not too bad. Plus also getting, or finding someone or place that'll let you use a 3d printer adds extra fun to the hobby.
Rubberband powered planes are cheap to make. Check out in the indoor f1d planes that can fly for an hour on one strip of rubber. You don't even need propellers though as loads of gliders you can make from free plans online. I want to make a radio controlled discus launch glider, that you throw into the air. once you get a transmitter/ controller, you can make loads of other models cheaply that all work with it.
@@GrumpyIan if you are willing to tinker you can get a 3D printer pretty cheap too.
Here from Lake Washington, home of the iconic hydroplane races of Seattle, I might make one suggestion to your speedy craft. If you want the boat to carry more weight (ie a camera mount near the center of gravity) you might try covering your carbon tubes with an aerodynamic wing to give the hull more lift. This is how the unlimited class hydros carry their big turbines.
I lived in Bothell back in the 80s and watched many races on Lake Wasjington. The transition from the Rolls Merlins to the turbines was a bit sad but cool in their own way.
@@phillipzx3754 I completely agree. It was a sad day when the Merlins fell silent. They were no longer the “Thunder Boats” of old. With all the other activities of Seafair the hydro races just aren’t what they used to be. Everyone even knew the names of all the drivers when I was a kid.
Impressive! How did you choose the shape and dimensions of the hull? Could you give more details into this please?
What to do next: make it able to take a ramp and jump, go even faster and with a camera onboard!
What an epic transition. We see you building a hydroplane and testing on the grass. Next we see trials you conduct with varied responses. I knew when you added a rudder, you were going in the wrong direction. The drag and principles of physics on the hull changed. A purist hydroplane which has been used in the swampland of Florida is a tried and true form of transportation. When we see the next part of your video, you are surfing on an electric surfboard playing in the water with the boat!,
!!!!! Epicenas. I am inspired fully today by this. Will get to work now on boat and electric board today. Thank you for the inspiration i needed. Btw, beautiful nature to explore your inventions. Germany? Z
Fantastic!
Serious editing and lots of content. No waiting till the end to get nice info. Great video
Nice upgrade to the rudder! That RC boat is super fast! Thanks for the video share!
I enjoyed watching you solve the problems as they came up.
A fun video.
Hahaha, the classic story of the tortoise and the hare. Love it, awesome boat and video. Always love your work.
Perfect design to have some extendo wings! Go-go gadget!
Awesome project and insane speed 🔥 Love it! To increase steering efficiency you could add tiny vertical fins to side hulls inner wall low end. They would be in water to add side force and reduce front end sideslip.
This was way cooler than i thought it'd be
Great camerawork! You captured the feeling of speed perfectly.
Great Job. These things are quite hard to get just right with cg and everything!
I love that powered surfboard!!
Great content dude. Thanks and Blessings.
Perfect model!
Timothy Pastore's comment hit the nail on the head. The turn fin is key to making it bite on a turn. Mine is made from a blade cut down from a small kitchen knife. It is placed a bit ahead of the physical CG of the boat. I can turn at full throttle and it is perfect. You will not need an air rudder. I also mounted it with a bolt so if it where to hit a solid object it will swing back preventing the sponson from having the transom ripped out of it. As for getting it on the plane, I will hold my boat at the front from the side with the nose tilted up slightly. In other words my arm is extended away from my body to hold the nose, I am standing broadside to the hull. If you stand rearward you risk getting chopped by the prop. Rev the prop to about 30-40% throttle a gentle push and swing your arm out of the way. It is on the plane instantly. Hand to transmitter, then adjust your speed to suit. I have had it work every time, just took a bit of practice to get the right technique. Loved the video BTW, thanks for sharing.
Blown away that the crash didn't destroy the boat... nice one!
Thanks!
Häftigaste bygget! Vilken speed! Grym video
What fun life you have creating these kind of vehicles. And handy to have this lake near-by, winter,summer, its all good
the hydroplaner looks very cool simple enough and fast. good job
Drifting hydroplane is something cool I did not expect to see. It's awesome!
I never do it otherwise. Using a turn fin makes it get stuck in waterplants. I do use a rudder, but it lifts from the water as the boat starts to plane.
Really amazing results for what it is. Great job.
Wooosh that's fast. Looks cool too. I love the air/water rudder. Id love to see it go over a water ramp and get some air!
Good job. Great evolution in your design that resulted in a very fast boat.
You sir.. are a true engineer..
Excellent video. Very impressive boat and an entertaining lunch break.
totally awesome. loved it!
I feel like rctestflight could make a great addition to this collab.
loved the build man! Cant wait to watch the next video Simon!!
Love to see you uploaded a new video! I’m sure it will be great! 👍
That’s awesome , great job . Insanely fast.
DOH hitting a stationary object. Nice build 2x👍
Amazing work!
Love Simon's playground ... 👍
The drag from the motor support is huge. Square edges everywhere.
Scary fast boat. But that surf board is still by far the coolest thing I've ever seen!
Another amazing video Simon, good content and fantastic shots and filming quality!
It's always a pleasure see your creations! 🔥
Very fun toys there, Simon. Good job on that.
Always enjoy seeing your uploads, gives me inspiration to build my own projects 🤟
Nice collaboration 👍🏻
you may not have won the boat race, you certainly won most awsome hydroplane speed built. This is so amazing!
I built and operated just about everything radio control. Old and broke now. Never finished my last project. A boat design very similar to this. I found a masters thiesis on the design and function of a neutral lift highspeed . I believe you can set a world speed record with this sponson !
Regarding expanding insulation foam: If you use the "Door & Window" one it doesn't exert as large an expanding force as other foams.
Your videos are always so high quality ....love it
Great job
WELL DONE
Extremely cool!
Awesome job and beautiful design!
slow and steady wins the race!
I would like to see a ground effects vehicle. That would be quite a challenge but I have confidence in you!
That was excellent, Jolly Good Show!
More footage so cool
Good one..always enjoying your videos. Keep up the good work.thanks man
It looks beautiful there
Solid engineering!
One of the very few channels I literally stop everything to go watch.
This was fun! Next build: Airboat, or any type of airplane that can land on water.
Impressive work, I really like how you show your experimentations with different designs. From the perspective of a physicist that only have experience designing vehicles in KSP it looks like your thrustvector is ofsetted from the center of gravity such that the force from the engines would press the nose down in to the water (and thus increase the friction). Maybe you could get to even higher speeds by lowering the engines closer to the central line? Could at least be worth trying.
thanks wonderful
Awesome work. As I assume you may know this is really a variation on the Bluebird hydroplane, which was a 1950's concept. There's a lot you could do on the aero for your air fin, and combine that with a smaller water rudder to achieve better performance.
That is a really beautiful lake.
impressive work! keep up the great videos. love it!
AWESOME!
Awesome job.
This moment 7:20 is the best moment all your videos could be you doing this.
AMAZING!!!
such a beautiful story
Yes! A new video.
Well done.
Sweet design and build. Sweet editing too.
Slow and steady wins the race
What a cool build, looks plenty fast !
Amazing work, dude! Brilliant boat!!! Well done! 😃
Stay safe there with your family! 🖖😊
What a beautiful lake!
Keep up the good work!
Awesome boat Simon! I’ve also built a hydroplane boat very similar to yours, but from fiberglass and using a EDF instead of a regular prop motor, it looks like you’re worked much better than mine though, great video!
Very nice!
