DIY Electric Hydrofoil Part 14 - Updates and Ocean Test

[@MaxMakerChannel]

So can you share some build tips and details with us ?

[@laurentjobart9297]

Good to see you back, was getting worried that some shark tried to bite the foil. Hope to ser you soon on new vids

[@thisourventures]

After watching your video and saw how versatile your Element are, I ending buying one. And the funny thing is that it is the same color as yours. Out of 15 owned vehicle that I had, this is the best! I finally found the right vehicle that fits my lifestyle.

[@pacificmeister]

RoPower haha that's awesome. Glad to hear. Best car in my car history as well. And mine pops up and sleeps two people on top. It's also 4x4 which is great for driving to our remote kite spots in Mexico.

[@juliansjames]

Thanks for continuing to share your efforts. Really inspiring!

[@juliangoulding]

Good to see anouther vid! What's the next project!!!???

[@CS-ys8jl]

Nice work 👍 looks like fun...

[@KayakDIY]

In your design build you reference the battery box. You said no glue sticks to that material. Possibly 3M VHB would work for your needs. I use it on kayaks to secure mounts.

[@pacificmeister]

If that's the tape with the red peel off, I am using that. Sticks everywhere. Best tape ever. Thx.

[@_a.z]

Brilliant! This is the sport of the future!!

[@LSUtiger607]

Can you provide any notes about the waterproofing of the housing? Any leaks? What worked? What didn't?

[@TeamEdgeGames]

How much would you charge if we had you make us one?? They're so cool!

[@pacificmeister]

Haha. What will the Edge Game with it look like?

[@TeamEdgeGames]

I don't know, but we could do something awesome! We could do a race or make some obstacle course for the nearby lake

[@pacificmeister]

sounds fun. let's discuss. pm me.

[@TeamEdgeGames]

pacificmeister what is your email? If you want to email us, our email is [e-mail]

[@IevgenZhalnin]

Hi. i'm interested in your project too and wondering how much it's gonna cost me if you build one for me? [e-mail]

[@MaxMakerChannel]

How do you cool the ESC? The aluminium plate is out of the water.

[@pacificmeister]

If you look closely at the videos you see the back gets hit with a thin water spray while foiling. But it's also good to land and cool once in a while.

[@MaxMakerChannel]

Thanks. I was curious if that was enough. Did you consider adding some sponge or cloth to keep it wet? I wand to put my motor into the board itself to make gearing easier. But then cooling is an issue.

[@pacificmeister]

Probably not enough for very long rides. Needs more testing. Noise could be annoying with motor in board. It's beautiful to fly over he ocean almost silently :)

[@tomvandernoll1455]

Can you give a view details about the motors(maybe a link) to the motor you had the most succes with.

[@pacificmeister]

Tom Vandernoll - I recommend efoil.builders, lots of discussion on motors. My build is here, check the list of materials for links to the parts: efoil.builders/t/pacificmeister-build-info-and-cad-sources/21

[@philippeprouff6794]

Hello it is with great joy that I am your adventure and a big congratulations for your work. I would like to ask you a small question, I also have a project with an electric thruster , I got a PARKER PV40TN reducer but it does not connect to my motor in 0.39 "(10mm) because the PARKER reducer is in 0.37 "(9.5 mm), can a drill bit be passed through the reducer? thanks in advance

[@pacificmeister]

I know the pain. No idea why Parker makes the input 9,5mm. Looks like 3/8inch in and the out is 10mm... what solved my problem was buying this kit: Parker MV40-007 Mounting Kit. It comes with an adapter from my 8mm motor shaft to the Parker. Not sure what's best is for you with a 10mm shaft. I probably would try to grind the motor shaft down rather than drilling the Parker. Never tried but maybe it works when you power up the motor and hold a file to it. Good luck.

[@philippeprouff6794]

thank you for your answer, or can I get the parker kit if I go with a motor in 8 mm?

[@pacificmeister]

Yes that worked well for me. Or get a german Neugart PLE40 which is available with 8mm input and fits snug on my 8mm Motor. My current setup.

[@NicolaGrossenb876]

Hi Pacificmeister, war wiedermal toll eins deiner Videos zu sehen. Bin zur Zeit auch sehr im efoil projekt fieber, da ist es extrem wertvoll, solche Videos haben zu können. Bei deinem Resultat stellen sich mir folgende Fragen: wie lange surfst du mit 44Ah, respektive was ist dein Stromverbrauch, wenn du schön gas gibst? Und: Ist es wirklich so essentiell, eine 5:1 Übersetzung zu verwenden statt den Motor direkt auf den Propeller zu führen? Du machst das ja scheinbar weil du mehr Drehmoment erzielen möchtest, ist der Motor ohne 5:1 Übersetzung so träge? HABE DEN 56114 450KV gekauft mit einem Seashark 200A esc und werde mit eine 50Ah 48V Batterie zutun. Danke dir jetzt schon für die Rückmeldung, Grüsse aus der Schweiz.

[@poison66]

It's cold. I've made one, too. I can't find the right board. It's going on next year. I thought you were missing

[@pacificmeister]

赵海良 hey great! I just saw your videos. Sorry to see the broken board. Where are you based? Winter break? Lucky me all year testing here in LA :)

[@malyan77]

Hi. Great to see your progress! And in the begging you mentioned that You burned direct drive motor... Can you share your experience with this direct drive - what motor did you try and how did you managed to burn it. And did you manange to set your board on foil with this direct drive setup? We are now trying to make electrofoil with low KV outrunner motor for e-skateboard as direct drive. So may be we are on the wrong way...

[@pacificmeister]

Yeah that's what I tried. Good luck pulling the heat out through the stator mount. Much easier to cool inrunners where the coils are outside. Only way I can see this work is if you are running the outruners wet. Tried that too with a 60kv but not enough power. Maybe with 2. Corrosion was also an expected issue in salt water here, I didn't spend time to epoxy stator or replace bearing with nylon or ceramics. The ROV community has been experimenting here too. Worth looking further into it. Keep me posted on your experiments please. Good luck.

[@malyan77]

what power did You use? we are looking on alienpowersystem.com/shop/brushless-motors/alien-6374-outrunner-brushless-motor-60kv-3200w/ - as far as we calculated 3200 w at motor should be enough - or it is not? and can you give a link to rov community? as for cooling - there are options with watercooling but with higher KV - alienpowersystem.com/shop/brushless-motors/wc80100-outrunner-brushless-motor-180kv-7000w-watercooled/ - may be this is the way to solution...

[@malyan77]

By the way, guy from alienpowersystem.com sent my following mail: "Our new motor is been developed for these application. it is a 58mm inrunner, 110mm long, 8kw, kv from 50 to 100, power input from 12 to 18s. it will be made with watercooled version. Price will be roughly 150-160 GBP"

[@pacificmeister]

Nice! When is it available? Don't think we want an extra water cooling feature/sleeve around the inrunners though, makes it too thick. We have our own direct water cooling if it sits flush in the aluminum tube.

[@malyan77]

Yes, I think so too - that for inrunner there will be no need for additional watercooling. As for availability - they suggest that i should write them in 2-3 weeks. So hope, that it will be not too long...

[@MrAaroncrf]

@pacificmeister , Very cool project! In the board with the aluminum cooling plate, what ESC are you using and what kind of adhesive or thermostatic are you using to adhere the ESC to the cooling plate! Thank you in advance!!!

[@pacificmeister]

Still using the Seaking 130A ESC. ESC is bolted with an aluminum sleeve onto another aluminum plate, which is tapped and attached to bottom plate with 2 little screws covered with a little epoxy for sealing.

[@JRPW]

Those batteries are insane!!!

[@_a.z]

What's the motor pulling? Looks like batteries give about 1kW/H ??

[@chriswin1st]

OMGAWD OMGAWD OMGAWD!!!!!! this thing is amazing. i'm hoping it didn't come out costing $12k to build like the one selling online. It's also great that your son's involve in the process too. With my work load and if I start in Feb 2018 when my son will be born, my board will be ready when my son is about your son's age in the video =P

[@AntonioCheong]

Cool! But why not just use a PWM generator with a wire instead of a RC remote?

[@pacificmeister]

Yes totally possible if you don't mind the wire

[@RodParmenter]

Have you considered a larger front wing?

[@pacificmeister]

Yes. And smaller ones too for higher speeds. I'd like to change wings based on conditions and mood in future. Big wing for wave days, high aspect wing for riding to work fast.

[@RodParmenter]

thanks for the reply- I'm using a GoFoil Maliko in the Columbia River with wind swell. vimeo.com/231143905. I don't have a motor yet!

[@lightmeupsigns5363]

Hello pacificmeister great videos May I ask you did you end up settling on the SSS 56104/500KV Brushless Motor and 7:1 inline gearbox ? or do you have a different setup now using a bigger brushless motor direct drive? Also is the impeller your using approximately 120mm DIA or larger ? Your help would be really appreciate mate ! cheers steve

[@pacificmeister]

My current gearbox is 5:1 with a 123mm (good guess) prop. I am about to release all sources and details. Stay tuned.

[@LowCostCncRetrofits]

pacificmeister thanks for the info mate one last question are you still using the same 500kv black motor ? Cheers

[@pacificmeister]

Yes still using my first original SSS 56104 500kv

[@lightmeupsigns5363]

Thankyou !

[@CarkeekW]

When getting up always put your front foot down first as it stops the board popping onto the foil prematurely.

[@superjaykramer]

Are they lithium ion or polymer batteries?

[@pacificmeister]

Lithium Polymer - see all build details and CAD sources here: efoil.builders/t/pacificmeister-build-info-and-cad-sources/21

[@DIYElectricHydrofoil]

We are testing a direct drive setup this weekend, www.DIY-Electric-Hydrofoil.com should be interesting and we haven't seen anyone with a setup this yet (80mm 4 blade Kort Nozzle), hoping it may work well.

[@vincentbraillard26]

DIY Electric Hydrofoil hello. Yes me. I'm use a direct drive to. If you give me your email i can send some picture. I'm a litlle bit afraid because everybody burn his motor. Can you give me your feedback after test on my email. [e-mail] Thank you very much

[@odessalive8230]

hi, how to made waterproof motor shaft hole ?

[@sylvainmassicotte5877]

Even if the power control box it is a seal one ,all connection should be grease d with diėlectric grease ,sold at NAPA car part store,to keep and encreased the conductivity

[@bruceschneider4928]

Have you considered coating the controller in Plasti-Dip? That would free you from the zip-lock baggie while keeping the controller waterproof. The stuff is cheap enough that if you need to access the controller, you can peel off the Plasti-Dip, then recoat it.

[@faitron2]

Great project! TIP= Dont discharge your lipo under 3.6v per cell. If you put 3.3v it will reduce the lifespan.

[@pacificmeister]

Right 3.3 is low, will bump it up. Thx

[@sabyx5]

3.75 better for lipos, expand its life. ( I fly rc planes..)

[@auleefor]

Hmm, not quite accurate like this. Lithium cells don't like being empty or fully charged. Store them at 3.85 Volts makes them happy. Charge only before using them. And don't run them down below 3.3 Volts, especially under high current draw conditions. If you switch them immediately off reaching 3.3 Volts you'll observe the voltage goes back to nearly 3.6 Volts which is considered not harmful. Anyway because of the chemical constitution of high C rate Lithium cells, outgassing still occurs over time and 500 charge cycles are not quite real. They loose capacity over time very fast and stay around 80% for most of the time till they get worse again at the end of their life.

[@donaro]

how long can it run?

[@xenofonlive]

how Watts needed under load?

[@Bantiegames]

haha i love this video, its me linus!!!

[@JeremieTronet]

Awesome !!!!

[@sylvainbaffard7433]

J'adore ce top merci quand en France

[@jonathanhutsler763]

Kleiner Tipp für die RC Steuerung wasserdicht zu machen einfach ein Ballon als Hülle nehmen ;)

[@DIYElectricHydrofoil]

Yes, excited to try 80mm prop. As for balloon, it would mess with the remote trigger, if that is what you are saying to use it on?

[@jonathanhutsler763]

DIY Electric Hydrofoil Just use with the new Remote Control from Graupner Hot. ITS little and cheap. Good wishes from Germany

[@DIYElectricHydrofoil]

which one can you please send a link Jonathan

[@DIYElectricHydrofoil]

Hey thanks, interesting, Im looking at anotherone as well, may get one take it apart, dip all electronics into comformal coating and test it as waterproof, it should work, low voltage is safe, question is for how long? I have seen it done before and worked exceptionally well.

[@TheBlackicehunter]

excellent

[@elevateinflatablee-foilpro7455]

Hy pacifikmeister. If you want to get rid of the transport problem of the whole thing and for easier starts, try a bigger board..like a SUP. We invented an inflatable SUP with rigid Mast attachement. Check it out on www.elevate.rocks Btw. how many AMPS &Volst(Assume 50v ?) you need for lift of and how much if your flying. Would be interesting to evaluate efficiency as we use different propulsion (kind of impeller)

[@pacificmeister]

Very cool! I'll follow your progress. Not sure about "worlds first", Don has been building and riding inflatable versions of his Jetfoiler years ago :)

[@elevateinflatablee-foilpro7455]

Hey danke, hatten versucht Dich zu kontaktieren, aber leider ohne Erfolg;-) Wenn Du Zeit hast schick uns mal ne kurze mail oder über FB facebook.com/www.elevate.rocks

[@pacificmeister]

Alles klar, ich ping Euch

[@ivan.kucherenko]

It is great!!! How much does it cost now? Could you please update the List of materials? www.dropbox.com/s/d31ti8819uahmyv/List%20of%20Materials.xlsx?dl=0 or is this a complete different built?

[@tclark]

I have a list of materials that I've been keeping up-to-date in Google Sheets. Very similar here: goo.gl/xGZd7H - Follow along with my project at www.efoilbuild.com

[@pacificmeister]

Yes there are a few changes. Will update the list soon.

[@patrickmckowen2999]

Very nice Cheers

[@rasmusnygaard1870]

I think you will be better of with a more modern front wing. All the big companies are starting to make effective and easy driven wings in big sizes, so they can go super slow to. That old LF foil has sooo much drag, and I can see that you are struggling to keep it down. All that downforce you are providing is just wasted energy. For example take a look at Ketos XL front wing. It's a easy upgrade and will make a huge difference

[@pacificmeister]

Agree. I feel I could hit easily 30mph with that setup with a more efficient and faster wing. For now I am happy.

[@joannawie]

great!!

[@tclark]

Great to see the duct is back! Super cool. Following your build with slight modifications here: www.efoilbuild.com

[@pacificmeister]

I saw it. Very nice. Good luck with your build

awsome bro

[@rouijelhassan3168]

Welcom to serf marocco

[@darrensoong3829]

I am super impressed with what you have done! I bought a high priced Lift efoil and I love it but it does not compare to this DIY experience you have done. Also, what a great learning experience for your son! Congratulations to you! There is no way I could ever have done what you have done on my own. My efoil video is kzbin.info/www/bejne/n4vRi6inmcemf9U. But, I am humbled by what you have accomplished and wish you continued success!

[@DIYElectricHydrofoil]

Amazing and so glad you are back! I was worried something happened with that open prop... YIKES! You started the DIY revolution and by next summer the DIY community should have a couple awesome versions to build and its because of you paving the way PacificMeister! Did you talk with the guy (P R Gauvreau) offering his waterproof controller for 12S? I would love to get in touch with you both. [e-mail]

[@pacificmeister]

Thanks Chris! Are you foiling on yours yet?

[@DIYElectricHydrofoil]

We plan to get up this week, just waiting on another part, you know how it is, painfully slow for some parts :) Would mind sharing what worked and didnt work with your 500KV motor? direct drive burn it out? what were amps and prop sizes you tested with particular motor?

[@johns.1940]

Awesome!!!! Thanks for the inspiration!!! Lucky kid, you got a great dad!!!
