Re: Electric Hydrofoil/E-Foil

@Hiorth: I´m thinking of using your propeller for my setup. Do you know what rpm you used it with when foiling? I´ve ordered a PLE040 5:1 but the manufacturing/delivery got delayed (everyone needs a gearbox for their DIY Efoil ;)) so I bought a used PLE040 but with 8:1. As I´m using a 290KV with 15S...

Re: Electric Hydrofoil/E-Foil

How far up from the fuselage do you guys set the motor? I suppose that this depends on the ducted propeller size but also it maybe easier to not have to far down. On kite hydrofoil we tilt the board when going upwind and therefore you need a long mast to get above the waves without getting the wingt...

Re: Electric Hydrofoil/E-Foil

Hi All, I had some success this weekend with my build. I was ripping around the bay for about 25 minutes and used up about half of my 12S 16Ah pack. I found it quite a bit harder to ride while trying to maintain throttle and balance, with all the force coming from the bottom of the mast. I eventual...

Re: Electric Hydrofoil/E-Foil

Does anyone here have knowledge in what type of lubrication to use in the planetary gearbox like Neugart or Parker when using them with hight input rpm? Should the gearbox be filled with oil? Does anyone here have experience in laminate carbonfiber/epoxy onto PLA? I would like to 3d print the mast ...

Re: Electric Hydrofoil/E-Foil

Printed with pla, infill varied slightly but most parts were printed at 70 percent. Sealed with epoxy resin. O rings and marine 5200 used between sections. Nice job! Seems like you also nailed it. Good looking foil. When you say "Sealed with epoxy" does that mean that you can not open it ...

Re: Electric Hydrofoil/E-Foil

I angled the rear wing of the foil, and the foil mast to make the foile fusalage more parallel to the board, It made huuge difference in riding experience! much easier now :) Also did a thrust test, with no rider: https://www.facebook.com/nikolai.hiorth/videos/10159559344945144/ Its amazing how muc...

Re: Electric Hydrofoil/E-Foil

So we have the board up and running, and it works nicely. Will post a detailed instruction with all cad files, part lists etc on Instructables.com this week, if anybody want some inspiration or propeller design that works you should check it out. Will post a link here, once it is up. We will start ...

Re: Electric Hydrofoil/E-Foil

What type/size of cables do you using from the ESC to the motor? I bought 10 AWG but when I received the TPPower motor I notice that they are much smaller. Could it be silver that reduce the need for wider diameter? According to the spec it could take 109 amps.

Re: Electric Hydrofoil/E-Foil

Will make my Onshape document (contains all 3d files etc) Public so that anyone can copy download and edit parts. Will also upload to grabcad, but will wait until I know it works (hopefully this weekend). This would be awesome, thanks in advance! I am especially interested in the prop and duct if t...
