I know it's crazy. And I only used one third of the power that the motor is capable of. I tried out 12S and got to 25km/h but after a few seconds the voltage of the batteries was too low and the cables got hot. I think that a dual motor setup would be the best way to go so the controller doesn't need to be so expensive.
EXACTLY...KEEP IT SIMPLE STUPID....better to ride briefly on a nice simple design than having something on the drawing board for five eyars like that efoil idiot
Build remote in the oar... waterproof battery box completely maybe paint the box .... you will be onto a great mini power board ... although find stronger batteries.....
You should design a small rudder to steer with. Also all that techno-gizmo stuff and yet you still hand pump it up? They do make electric air pumps for this purpose.
This is radical! I want to try this but with my own (self made) board! At first when I saw you putting the small propeller on I thought “oh this isn’t going to go anywhere”, then you scooted around the pond a dozen times lololol
At first I had a 70mm propeller and it was too slow :) I was not sure if the fin attachment point is strong enough. But I can hold my weight and won't rip off. I'm still waiting for new batteries but for the next video there will be some improvements and I will record the speed on GPS.
Wow, very awesome. It's faster than most trolling motors. W/ bigger battery, it'll travel further. Cool way 2 bring a boat, an inflatable board. Thx 4 sharing on Utube.
I’d rather see a jet pump drive rather than an open propeller. If the motor controller fails or locks up to full power and somebody falls off a really bad accident might result with an open propeller.
Awesome video my man! I'm about to just fiberglass in an outboard mount and front lanyard eye onto a board and give that a shot. The way I figure it, having a lanyard to hold like a ski rope in one hand and the the tiller handle (actually the handle extension) in the other, I should be able to keep balance and effect turning better by simply turning the engine a few degrees.
as someone who is used to getting towed behind boats and the dangers involved with being in water in proximity to a turning prop, i really suggest you should try to switch to an impeller design. a metal prop this big is quite dangerous and per design you are close to it in the water. don't get hurt!
If it hasn't been said yet, you should attach your remote control to the end of the paddle, but so you can use either hand to control it or steer. Fun idea though! Makes me want one for my kayak! :)
Good job buddy ! Always fun to build stuff out of hobby parts ! My 17 pound model electric boat has a single 8400w brushless motor . You could get really crafty installing model boat stuff on almost anything.
I actually saw a video a few years back where a guy regrew his finger using stem cell powder. Still wouldn't feel good to lose it in the first place tho 😅
That thing hauls! Not sure how long the batteries last, but it goes fast in the meantime. The speed controllers will shut down the motor if the battery voltage is below a set point to protect the batteries from damage.
The theoretical maxium of my setup with the 222Wh LiPo batterie is 3 minutes of full throttle. There is room for improvement with bigger Li-Ion batteries :)
Brilliant, well done! Would you consider a spot/mechanism that would allow you the lock in the paddle in a vertical position so you have something to hold on to while standing? If the paddle could then be easily removed you would have a way home if battery dies or any malfunction.
Would like to know what parts you used and where to find them. I would think that if you incorporated the remote into a ski handle and rope attached to the board it might prove helpful. Also, buy a can of CorrosionX. It waterproofs everything. Check the ad on their website. They fly a helicopter out of a pail of water. I want to convert my old windsurfer board. thanks jim
I love this project, really cool! That 94mm prop is really big and will have massive drag. Considering this motor is 700kv, maybe a smaller prop with a greater pitch will allow the motor to spin faster and more efficiently. Increasing the cell count will do wonders also. Your motor can run on 18s, if I am not mistaken. As an old rule of thumb, a prop for submerged drive will have a diameter similar to the diameter of the motor, which in this case is 56mm. However, this motor is VERY powerful, so go for something like 70 - 75mm. The 56114 is also available in a 350kv version, which would be an even better option for this application. The 350kv version can take 130 volts, but requires a lot less current. Just a few thoughts...
Hey man you are correct and its cool to see somebody with alot of knowledge summing all these details in one single comments! My question for you is can I measure amp draw with clamp ammeter on 1 of the 3 phase wires of the motor? My ammeter is AC only, can't measure current draw coming from the battery. Thanks!
@@Eden_M I have never measured current using one those clamp meters, but it should be possible. Wattmeters are inexpensive and I find them useful. On my RC boats with submerged drive prop, I check the current draw with the boat held still to get an idea of what the motor is pulling and to make sure the whole package is not overloaded. Only then will I run the boat and experiment with slightly different diameter props and/or different pitch. All the while I keep a close eye on temperature of all components. I try to be methodical in my approach, for example taking notes for comparison later on. Stick with it Eden, and your project will succeed! Good luck!
Interesting. I think the 350kv motor will be better suited for 12S, but I will torture my 700kv motor untill it brakes. I tried a 70mm 4 bladed Propeller with 0,8*70mm Pitch (7008). It was with 6S and worked pretty good but I thought it was too slow so I made the video with the 9408 propeller. However I lost the propeller in the lake and now I'm waiting for a new 9412 propeller. Here you can see a thrust, power to RPM chart of the 7008 Propeller: ae01.alicdn.com/kf/HTB1GNXjTAPoK1RjSZKbq6x1IXXa0.jpg Here for the 7012 Propeller: ae01.alicdn.com/kf/HTB1I.pGTxnaK1RjSZFtq6zC2VXay.jpg Here for the 9408 Propeller: ae01.alicdn.com/kf/HTB1T.plTpzqK1RjSZFvq6AB7VXaL.jpg And here for the 9412 Propeller: ae01.alicdn.com/kf/HTB1yqlhTAzoK1RjSZFlq6yi4VXaY.jpg So with the new Propeller (9412) and 6S I hope its possible to tow a wakeboarder. Or on 12S to get as fast as possible, put some wings on it and 2x4kw of Air Propellors and motors and fly in ground effect...
@@EOLAND99 I ordered an rc wattmeter but I don't have it yet. I do have 2 clamp meter/ammeter, do you mean I have to use both meters simultaneously on two different phases of the motor?
Wow impressionnant. Tu n'a plus qu'à trouver un moyen de pouvoir faire tourner l'hélice avec la télécommande. Bravo y a de quoi bien s'amuser avec ça 👏👌😉
Gar nicht :D Im süßwasser hatte ich bisher gar keine probleme. einmal kam sand in den rotor rein und hat das kevlar ein bisschen zerkratzt, aber konnte ich mit mehr epoxy wieder reparieren.
are you planning to put the controls inside of the paddle? if not I strongly suggest that you do so many of these paddles are hollow in the shaft so you can throw all of your electronics in there.
Well done !! excelent video ... can you give us 1. how long the battery holds 2. did you buy all together as a kit or did you bild it by your self? 3. costs?
This thing looks Not Like a kit. He says that the Motor draws about 160 Amps and those batteries look like 8 or 10ah. Im guessing it could last 30 minutes or so on Full Power. As for cost, my guess would be 200-ish. At least those are the cost for those componets here in Germany .
So my 220Wh lipo and one motor with 3500W you can have a maximum of 4 min of full throttle in short bursts. I use my battery only for testing not for long duration. I'm hoping to find a more efficient propeller and the voltage needs to be increased, so the Amp draw is not over 100A for more efficency. In total I think a selfmade version with a good battery can be build with 700-1000€ with the board included. Difficult parts are the Propeller adapter and the motor mount on the fin.
@@batziii8745 6S 10Ah batterie => 220Wh / 3500W = 0,062 h = 4 min on full throttle 23km/h 220Wh / 800W =0,275 h = 16 min of medium throttle at about 15km/h
This is exactly what I was thinking when I bought mine ....it's a little zodiac lots of sold square inches of floatation a little electric motor would be nice ....an e sup board for just touring a bit without a lot of noise and huge launching deal in the bays in the ocean .
The cost for all materials will be under 700€ and if you know what to do you could build it in a few days. However it took me half a year and some failed attempts to figure out a working design. Right now I'm working on a new motor with a bigger propeller to see if it works better. So the best would be to sell a kit which you could attach to any inflatable SUP :) Stay tuned.
Despereaux Nice work!!!... Is it an out runner motor or in-runner? I suspect a cowling or a fairing around the front and back of the motor will help boost performance and improve flow over the propellor. More blades on your prop may also help as you have lots of torque with the Emotor, and blade area will give you more thrust. Perhaps going to 8s will help as you can lower your losses due to the lower current pull. I’m looking forward to your update!
This is *super cool* I had no idea they sold such powerful motors for RC boats. I like the way you adapted it to your SUP. What kind of run time can you get on your 10A lipo batteries? I think one or two of these motors would be sufficient to power a small dinghy. *ideas are brewing*
Hey man nice build clean and simple and it looked wicked fast. I think you will be happy with 12s cause your amp draw will go way down. What size prop did you use? It needs to be inside a mortar nozzle to increase efficiency and also to protect the rider and anyone in the water from the prop. My first build had a prop and no killswitch and I have the scars to remind me of it. I use only jet pumps now as props make me very nervous. However I plan on building an e foil soon so your set up looks like it will work well fir an e foil you were planing as soon as you hit the throttle Nice job congrats on a successful build Cheers Frankie
Thanks :) I used a prop with a 70mm diameter but during a second test it unscrewed itself while braking and sunk to the bottom of the lake. So i ordered an 188mm diameter propeller since i'm not worried about the motor overheating. The pitch is higher but i hope it will work anyways without too much cavitation. I think a mortar will add quite some drag and my goal is to reach speeds over 50km/h. If i have a good working motor propeller combination i want to put is on a hydrofoil too :)
Despereaux Well that sucks losing your prop. Next time drill a hole through the prop shaft in front of the nut and put a cotter pin through it. So 180 mm from 70mm big jump ....you looked like you were going. Pretty quick in this video 180 will either fly or shake itself to bits. But hey it’s worth it if it flies🤙🏼 probably too much prop for a hydrofoil though. If you want a great cheap hydrofoil kit check out clear water hydrofoils he has a wood black kit with mast,board mount, fuselage, and the front and rear wings for $139 usd I believe. You have to glass it all up and it’s a lot of fiberglass work but pretty cheap and since you will be modifying any foil you buy why not do all your wiring etc and them glass it into the mast etc . If you don’t want to do a lot of glass work he sells a foil that has an aluminum mast and fuselage and composite wing and foil and I think that’s about $550 usd so not too bad. I got one of the wood blank kits. As soon as I have finished the double pumper twin jet powered board I’m currently building then the hudrofoil is my next build. I should be testing the double pumper this weekend and I’ll post a video after the test food or bad lol. Looking forward to seeing your 50kmh board. Good luck Btw what inflatable board are you using. It’s very wide and short I like it🤙🏼 Cheers frankie
Great and simple applied engineering! How did you fix the prop to the motor? Such large motor must be 8mm or so, how did you fix a shaft with dog drive there? Also isn't that ruining the bearings in the longterm?
Thank you :D yes I kept it very simple. So the propeller is fixed to a steel rod with a screw glued in the 10mm steel rod. Then the rod just slides over the 10mm motor shaft and secured by one small screw. So yes the bearings are getting ruined because of the high axial load and i can wiggle the shaft now 1mm back and forth. So an axial bearing will be defininitly needed in the future.
Congratulations Christian! Excellent! I'm fabricating my own electric surf board and I would like to know if you can recommend me a kit for it (battery + motor + controller + propeller). Thanks in advance!
This would be awesome on the bottom of a kayak
I want one for my Oru Kayak! Definitely 👍
Faster on a paddleboard but you'd be the quickest guy to the spot(not including boats and jetskis)
Where se you a kayak?
I’m actually impressed with that speed!
18km/h :)
On a wakeboard and you in business

Best example I have seen of simple elegant applied engineering. Thanks for posting and for listing the parts.
If you could integrate the controls into the paddle, you could use that for balance if it was a long double handed kayak paddle
Spends many hours designing an electric propulsion system for sup, manually inflates sup.
All you need is a foil board and a water proof controller. That's a really fun looking project!
Really love the simplicity of the implementation. Motor instead of fin, very nice!
EXACTLY...KEEP IT SIMPLE STUPID....better to ride briefly on a nice simple design than having something on the drawing board for five eyars like that efoil idiot
That's a wicked start to a build! Second model should have a remote built into that paddle, would help tons.
Thanks :D
Definitily. I thought something like a thumb throttle for ebikes on the paddle would be confortable.
Get your weight further forward on the board so it sits a little flatter in the water and I think there will be less drag and even more speed.
I've been building FPV drones for years now and just started learning how to SUP. Looks like this could be a way for my hobbies to converge...
Finding a way to seamlessly combine the remote control and the oar would be a great upgrade
So much faster than other electric fins on the market- boost fin and blue ray- you will smash crowd funding
This video is getting recomended for a lot of people😂😂
Wow this is so good. The fastest easiest e- Prop setup on RUclips.
This dude's my hero!
You are one smart cookie. Loved this video. I would have laughed a bunch if you wired them in series.
Good stuff. How about modifying the paddle to have the transmitter inside the handle. Would be easier to control. & only one object to hold on to.
Wow 😳 thats amazing dude. I can’t imagine how fast it goes 👏
Awesome. Can you share a manual or guidence how to build such engine step by step?

Hey man nice build clean and simple and it looked wicked fast. I think you will be happy with 12s cause your amp draw will go way down. What size prop did you use? It needs to be inside a mortar nozzle to increase efficiency and also to protect the rider and anyone in the water from the prop.
My first build had a prop and no killswitch and I have the scars to remind me of it. I use only jet pumps now as props make me very nervous. However I plan on building an e foil soon so your set up looks like it will work well fir an e foil you were planing as soon as you hit the throttle
Nice job congrats on a successful build
Cheers Frankie
Thanks :)
I used a prop with a 70mm diameter but during a second test it unscrewed itself while braking and sunk to the bottom of the lake. So i ordered an 188mm diameter propeller since i'm not worried about the motor overheating. The pitch is higher but i hope it will work anyways without too much cavitation.
I think a mortar will add quite some drag and my goal is to reach speeds over 50km/h. If i have a good working motor propeller combination i want to put is on a hydrofoil too :)
Despereaux
Well that sucks losing your prop. Next time drill a hole through the prop shaft in front of the nut and put a cotter pin through it.
So 180 mm from 70mm big jump ....you looked like you were going. Pretty quick in this video 180 will either fly or shake itself to bits. But hey it’s worth it if it flies🤙🏼 probably too much prop for a hydrofoil though. If you want a great cheap hydrofoil kit check out clear water hydrofoils he has a wood black kit with mast,board mount, fuselage, and the front and rear wings for $139 usd I believe. You have to glass it all up and it’s a lot of fiberglass work but pretty cheap and since you will be modifying any foil you buy why not do all your wiring etc and them glass it into the mast etc . If you don’t want to do a lot of glass work he sells a foil that has an aluminum mast and fuselage and composite wing and foil and I think that’s about $550 usd so not too bad.
I got one of the wood blank kits. As soon as I have finished the double pumper twin jet powered board I’m currently building then the hudrofoil is my next build. I should be testing the double pumper this weekend and I’ll post a video after the test food or bad lol.
Looking forward to seeing your 50kmh board. Good luck
Btw what inflatable board are you using. It’s very wide and short I like it🤙🏼
Cheers frankie
Would work better on a smaller board then Add some foot straps so you can control the board standing up. Very cool 😎
Great and simple applied engineering! How did you fix the prop to the motor? Such large motor must be 8mm or so, how did you fix a shaft with dog drive there? Also isn't that ruining the bearings in the longterm?
Thank you :D yes I kept it very simple. So the propeller is fixed to a steel rod with a screw glued in the 10mm steel rod. Then the rod just slides over the 10mm motor shaft and secured by one small screw. So yes the bearings are getting ruined because of the high axial load and i can wiggle the shaft now 1mm back and forth. So an axial bearing will be defininitly needed in the future.
this is very very empressive!
Congratulations Christian! Excellent!
I'm fabricating my own electric surf board and I would like to know if you can recommend me a kit for it (battery + motor + controller + propeller).
Thanks in advance!
Sounds like some german engineering right there 🇩🇪🇩🇪
Wow that thing is frigging awesome 👏
What motor is that?! What about battery "range"?... Great job!! 🙂👊
Parts are in the Description :)
The battery range with 200Wh would be about 2km at best.
That's friggin awesome 😎👍
Get a foil under the board for more speed!
Pretty wild ... kids got talent!
Should integrate remote control on the paddle
I definitly will do that :)
good afternoon, congratulations on the project. how long does the battery last on average?,
Looks real fun, keep going could earn you some money 💰
Cool proof of concept
I was thinking of maybe a 200W paddle wheel for a kayak.
For longer battery life rather than high speed.
propellers are way more efficient then paddle wheels. If range is your priority then use a trolling motor and Lithium-Ion batteries :)
