Frictionless Hydroplane With Aerodynamic Steering

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?

[@UglyFatOldMTB]

I came here to say that usually hydroplanes have a skid fin that sticks down from one of the sponsons

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!

[@UppfinnarAXEL]

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.

Hi Simon. Your hydroplane is a beautiful build and fast as a rocket, awsome job 👍👊

[@duderguy1571]

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.

[@SixOThree]

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.

[@4ntig3n]

Awesome video! This really makes me want to get into model building, boats.. planes.. anything with propellers xD

[@GrumpyIan]

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.

[@robambrose4199]

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.

[@conorstewart2214]

@@GrumpyIan if you are willing to tinker you can get a 3D printer pretty cheap too.

[@KarlMiller]

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.

[@BazilRat]

Fair play for taking the L, good show.

[@WetDoggo]

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

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.

[@phillipzx3754]

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.

[@sleeplessstu]

@@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.

[@jaknowwho]

[@jordantobins681]

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!

[@spaideri]

Drifting hydroplane is something cool I did not expect to see. It's awesome!

[@arturama8581]

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.

[@rondo122]

Another amazing video Simon, good content and fantastic shots and filming quality!

[@classekaka]

Great camerawork! You captured the feeling of speed perfectly.

[@wideyxyz2271]

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!

[@pietlopsa9164]

Great Job. These things are quite hard to get just right with cg and everything!

[@tuomassyrjaniemi]

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.

[@Simon-cw4ce]

I found this KZbin channel a while ago and your videos really impressed me. Great regards from Germany

[@ziggy979]

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

[@gizmobowen]

Excellent video. Very impressive boat and an entertaining lunch break.

[@gordslater]

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.

[@tordjarv3802]

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.

[@allenmoore9848]

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.

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.
