    Electric Hydrofoil/E-Foil

    Thats really good! I'd love to see the internal design. Have you used a large thread from the mast mount to casing?

    I have the Yep 120A. I haven't used it in the water yet, but it should be fine with sufficient cooling.

    Was it quite cost effective or expensive? Did you just glue the joint between the housing and the mast mount again?

    The V2 is looking fantastic! Did you do the machining and anodizing or did you get it done elsewhere?

    The PLE 40 can take a maximum input RPM of 18000. I have the one designed for the Torqeedo 1003 outboard motor. I'd imagine its designed around an input max of 18000 as well, but its pretty solid so should be able to handle higher than that as well.

    I am using the grease that is already in my Neugart. After all it was designed for an outboard motor so should work. As for carbon - PLA, I have never done it, but would approach it as follows: - lightly sand PLA - coat with a layer of epoxy and let dry. - lightly sand layer of epoxy to prepare...

    - I also saw the rear wing was put on upside down, however you should be able to take the wing and shim off and then put it the other side. - Slingshot is manufactured in the east, so it wouldn't surprise me if one of those guys are the actual manufacturers. But I would think it would be one...

    Very interested to see what this looks like. No 4 looks like slingshots H1 SUP Pump wing. Should be a perfect match for an Efoil. Did you order via Alibaba or via email?

    Electric Hydrofoil/E-Foil

    It is, they just put 1cm of plastic into the hollow parts. I just drilled into the plastic, put a screw in, and then pulled it out. You can run 2 wires down each hole. I think its a bit heavier than the Liquid Force mast, but that doesn't really bother me much.

    The Slingshot hoverglide mast and fuselage are a very good price. I have the mast and baseplate and will be getting the fuselage when its in stock

    I'm taking a chance on the HK YEP120 Marine version. It's cheap and I wont be pulling more than 100A so it should be adequate. I'm also going to try get away without water cooling and instead use a heatsink.

    What material did you print with? What infill did you use? How did you seal the 3D printed material?

    I did say that it would ;)

    Ride that thing!!!! Looks fantastic!

    That's a very good price! You'll have enough torque with that easily!

    How much current did you pull with 8 cells?

    Electric Hydrofoil/E-Foil

    Well done! So awesome! I have found someone that's going to help me with a CNC so I will have my aluminium version soon. Super happy 8S works as I have 10mAH 8s just waiting for mine to be done!

    Looking great! Nylon is rather terrible to bond with anything! Are you not worried it might come loose?

    Electric Hydrofoil/E-Foil

    With a foil, the more weight you shift further from the foil makes it harder to control. Having extra weight in the board is very different from having extra body weight as you have less control over it. The advantage of having the extra weight down at the foil works much like a yacht centre...

    Electric Hydrofoil/E-Foil

    Frustration... I spent 2 and a half hours last night trying to fight my way through aluminium bar on a mini lathe in order to get my spacers done for the motor/gearbox. After that time I was left with almost the same aluminium bar! Time to find a large lathe or someone that can machine the parts...

    I used a seal calculator where you type in the dimensions and o-ring material and then then it says whether its in spec or not.

    Electric Hydrofoil/E-Foil

    I printed some test parts (without screws) and lowered the unit 1.5m under water. Then left it for 1hr 30mins and pulled it out. Didn't take a huge amount of water, but enough to cause trouble. But I agree with the not using seals on 3D printed parts. I will hopefully be cutting the new parts on...

    Electric Hydrofoil/E-Foil

    I want to urge all of those building to maybe do a waterproof test with the motor unit. I found that mine was not sealing properly and as a result it has potentially saved me a considerable amount of money! If water gets in and even if the motor doesn't go, your bearings will definitely corrode...

    Its much easier just to pull out the plastic inserts in the slingshot mast! I took a small drill bit and made a pilot hole. Then put a screw in and pull out with pliers. Each hole fits 2 wires.

    Electric Hydrofoil/E-Foil

    I don't think this is an issue, I think it is more a case of the board design that has been used thus far. I just think the angles of the foil with relation to the board allows the nose of the board to point to high into the air. I have a slalom board that I am converting into mine and what I...
